The present disclosure thus provides a magnetic sensing system that implements a magnetic multi-turn sensor and absolute angle sensor in conjunction with a rotating magnet for counting turns and providing rough angle position information, along with an incremental sensor system using a rotating disk that has a track formed from Archimedean spiral shaped structures to thereby provide a higher precision angle measurement. A magnetic sensing device comprising the multi-turn sensor and angle sensor is arranged in proximity to a magnet mounted to the end of a rotating shaft. The magnetic sensing device detects the rotating magnetic field to measure the number of turns and the absolute angle of the rotating shaft to a first level of resolution and precision. The rotating disk is also coupled to the rotating shaft and is formed from a magnetic material. The track is then formed in the magnetic disk such that a magnetic incremental sensor detects a periodically changing magnetic field as the disk rotates with the shaft. Starting from the angle measurement provide by the magnetic sensing device, the signal output by the incremental sensor can then be used to provide a higher resolution measurement of the angular position.

The present disclosure relates to a method of calculating an audio calibration profile for a three-dimensional space such as a room. The present disclosure achieves this by creating a model of the three-dimensional space using three-dimensional (3D) imaging techniques in conjunction with feedback from a sound recording device. The information gathered can be used by a digital signal processing (DSP) device to perform room equalisation. The information can also be used by beamforming audio sources to adjust beam characteristics to recreate the ideal spatial or surround sound experience at the user's location in the three-dimensional space.

Automatic ambient light cancellation for an optical front end. The present disclosure includes a coarse loop and fine loop in a feedback circuit configured to cancel out currents generated by detection of ambient light. An optical front end comprises a single-ended photo-diode connected to a transimpedance amplifier (TIA) followed by a buffer stage to generate differential output. A feedback loop controls a current digital to analog converter (iDAC) which is used to cancel out undesired current (e.g., from ambient light). This results in the TIA from saturating and maintain good signal quality with greater sensitivity.

Abrégé
Systems and methods for compensating a transmit signal for charge trapping effects of a power amplifier are provided. In certain embodiments, a non-linear filter is trained based on time aligning a first set of observations taken from digital transmit data prior to conversion to a radio frequency transmit signal, and a second set of observations taken from an output of a power amplifier that amplifies the radio frequency transmit signal. In certain implementations, the first set of observations and the second set of observations are obtained without decimation. Rather, decimation is provided after timing alignment. By implementing the DPD system in this manner, signal data is not lost by decimation and more accurate timing alignment between the sets of observations is achieved.

Impedance paths for integrated circuits having microelectromechanical systems (MEMS) switches that allow for electrical charge to bleed from circuit nodes to fixed electric potentials (e.g., ground) are described. Such paths are referred to herein as charge bleed circuits. The circuit nodes may be circuit locations where electrical charge may accumulate because there is no other path for the electrical charge to dissipate. In some embodiments, a charge bleed circuit includes a switchable device (e.g., a MEMS switch, a solid-state device switch, or a circuit including various solid-state device switches that, collectively, implement a device that can be switched on and off) that connects and disconnects the impedance path from a circuit node. This may allow the device to perform different types of measurements at desired performance levels.

The present disclosure relates to a field effect transistor (FET) structure. The FET structure has a substrate, an active region, a dielectric layer provided over a channel of the active region and a gate provided over the dielectric layer. The active region comprises a source, a drain and the channel provided between the source and the drain. The active region is surrounded by an isolation trench, such that width edges of the channel are directly adjacent to the isolation trench. Current paths run between the source and the drain, through the channel. The FET is configured such that current paths running proximal to the channel edges are reduced or weaker in comparison to a dominant current path running through a center of the channel. One or more of the channel, the dielectric layer or the substrate can be modified or adapted to provide the reduced and dominant current paths. In one example, the center of the channel away from the edges has a first doping concentration of a first conductivity type, and the sides of the channel along the channel edges have a second doping concentration of the first conductivity type, where the second doping concentration is greater than the first doping concentration. In another example, the dielectric layer is thicker over the sides of the channel and thinner over the center of the channel. In another example, regions of the substrate below the sides of the channel have a higher doping concentration than a region of the substrate below the center of the channel. In some examples, the FET structure has both the dielectric layer of different thicknesses and the different doping concentrations in the channel and/or the substrate.

Sakr, Ahmed A.
Abrégé
New antenna designs for realizing circularly-polarized antennas with a wide scanning range are disclosed. The designs are based on arranging four sequentially fed antenna patches to be considered as a single antenna element, referred to as a "super-element," in the overall phased array. An example super-element includes relatively short transmission lines to provide excitations for the vertically and horizontally polarized fields, with the transmission lines for the vertically and horizontally polarized fields being perpendicular to one other. A parasitic transmission line may be placed around a part of each antenna patch of the super-element to serve as a coupler to further enforce the field vector direction for keeping the circular polarization. With such designs, an axial ratio below 3.6 dB for scanning angles of at least 75 degrees at 39.5 GHz may be achieved.

The present disclosure provides a device for initializing a multi-turn sensor that initializes the sensor almost instantaneously, thereby consuming very little energy. The initialisation device is provided in the form of a conductor that is placed a small distance above or below the sensor spiral, the conductor being configured so that it crosses at least two opposing corners of the spiral. A current is then applied to the conductor to generate a magnetic field in the corner sections of the spiral to nucleate domain walls. Once the domain walls have been nucleated, the external magnetic field will drive the pairs of domain walls away from each other towards the adjacent corners, changing the magnetic alignment of the tracks as they pass through. As such, the spiral can be initialised very quickly by applying a current to the conductor in the correct direction.

The present disclosure relates to a configurable output stage for a DAC channel. The output stage receives an analog output from a DAC and outputs a signal to an output terminal. The output stage is configurable between a voltage mode and a current mode. In the voltage mode, the output stage supplies the analog signal to the output terminal as a voltage signal. In the current mode, the output stage supplies the analog signal to the output signal as a current signal. The output stage can receive user input to select the desired mode. Consequently, an integrated circuit can be implemented with multiple DAC channels, each having the configurable output stage. A user can choose how many channels they want to operate in a voltage output mode, and how many channels they want to operate in a current output mode, depending on their individual requirements.

Abrégé
The present disclosure relates to an integrated circuit with at least a first channel and a second channel. Each channel includes at least a DAC. The integrated circuit also includes a number of circuit elements interconnected between the channels. The circuit elements can be changed between a short circuit state and an open circuit state. Normally, each channel will operate independently of one another, using only the circuit components in its respective channel. However, the circuit elements are arranged to allow a user to combine part of the second channel with the first channel to improve the functionality and performance of the first channel. In particular, a state of the circuit elements can be chosen to combine components of the second channel with the first channel. For example, components (e.g. a sub-stage) of the second channel can be connected in parallel with corresponding components (e.g. a corresponding sub-stage) of the first channel. This may reduce the number of available channels, since the second channel can no longer be used as an independent channel. However, the performance of the first channel is enhanced. The presence of the circuit elements allow an end user to decide whether to sacrifice channel count for performance enhancements. For example, the user can provide user input to the integrated circuit to select how the channels are interconnected. Moreover, the integrated circuit does not use additional redundant circuitry to improve the first channel, and rather takes components from the second channel. As such, the integrated circuit can have a reduced size.

The disclosure provides different time of flight, ToF, methods and systems for using two or more non-sinusoidal control signals to achieve modulated output light and/or image sensor control with reduced harmonic content. In particular, the two or more non-sinusoidal control signals have different relative phase offsets or duty cycle ratios such that a combined signal resulting from combing the two or more control signals has reduced harmonic content. By utilising non-sinusoidal signals and effectively making using of the combined signal for the output light and/or image sensor control, the system is more straightforward and lower cost to implement compared with systems that use sinusoidal control signals, whilst still maintaining accuracy of the system by minimising the harmonic noise normally associated with non-sinusoidal signals.

The present disclosure provides a linear actuator apparatus, magnetic sensor system and method of use for detecting a position of a component driven by a rotatable mechanism in a linear direction. A magnetic sensing device comprising both a multi-turn (MT) sensor and a single turn (ST) sensor is provided within the same semiconductor package and placed in the vicinity of the rotatable mechanism. A magnet is mounted on the rotatable mechanism, such that, as the mechanism rotates, a rotating magnetic field is generated. The MT sensor measures the number of turns of the rotating magnetic field, which is translated to the number of turns of the rotatable mechanism. The ST sensor measures the angle of the rotating magnetic field, which is translated to an angular position of the rotatable mechanism. As each turn of the rotatable mechanism will be translated to a specific amount of linear motion, the amount by which the rotational mechanism has turned is proportional to the distance travelled by the driven component, and thus indicative of the linear position. Therefore, by placing a magnet and the magnetic sensing device in relation to the rotatable mechanism, with the multi-turn sensor providing the number of turns and the angle sensor providing the precise angular position within each turn, the measured rotational position can be translated to a corresponding linear position of the element being moved linearly as a result of the rotation.

PHYSICAL UNCLONABLE FUNCTION CONFIGURATION AND READOUT

Inventeur(s)
Holland, William
Spalding, George
Hurwitz, Jonathan
Abrégé
The present disclosure relates to configuring at least one pair of devices in a physical unclonable function (PUF) apparatus and reading out at least one pair of devices for determining a persistent random PUF output. The pair of devices may be readout by measuring a physical difference between the devices/components caused by random manufacturing differences, which may then be used to determine a persistence random PUF output. Configuring the pair of devices includes measuring the random manufacturing difference and, based on that measurement, setting a readout condition for the pair of devices, which dictates aspects of the readout process that should be used for that pair of devices. Each time the pair of devices is readout in the future, it may be readout in accordance with the condition that was set at configuration.

Abrégé
Physical Unclonable Functions, PUFs, are hardware devices designed to generate a number that is random (i.e., two identical PUFs should produce randomly different numbers from each other) and persistent (i.e., a PUF should consistently generate the same number over time). Over time, aspects of the PUF hardware may change or drift, which may ultimately cause the generated number to change, and therefore no longer be persistent. Failure to generate a persistent number may cause difficulties for other devices that rely on the persistence of the number generated by the PUF, for example as part of a cryptographic process. The present disclosure relates to monitoring over time the physical characteristics of the PUF that are used to generate its number, and thereby keep track of its reliability to generate a random number that is persistent. By monitoring PUFs in this way, it may be possible to detect in advance a PUF that is at risk of generating a number that is no longer persistent, so that pre-emptive action may be taken before the PUF actually fails.

Abrégé
Sensors and methods for determining the state of charge of a battery are described. The state of charge is determined in some instances by applying a current perturbation having a frequency to the battery terminals, monitoring the response signal, and determining the phase of the response signal. The phase may be correlated to the state of charge of the battery, so that once the phase is determined, a determination of the state of charge of the battery may be made. In some situations, the state of charge may be used to determine the operating condition of a load connected to the battery. In some embodiments, the state of charge may be used to determine whether the battery is defective.

Aspects of the present application allow for measurement of a calibrated resistance for a resistive film in a sensing element, such that effects from contact resistance and background resistance drifts due to factors such as temperature, strain or aging can be reduced or eliminated. In some embodiments, by taking a plurality of two -terminal resistance measurements between various pairs of electrodes on a resistive film, a contact-resistance- independent resistance of a reference portion of the resistive film can be determined. Further, a contact-resistance-independent resistance of a sensing portion of the resistive film can be determined based on a plurality of two -terminal resistance measurements between pairs of electrodes. The resistance of the reference portion can be removed from the measured resistance of the sensing portion, such that variations in the reference portion resistance that are not caused by a sensed environmental condition may be compensated.

Described herein are techniques of characterizing electrical characteristics of a battery cell. The techniques employ a battery monitor coupled to a battery to measure voltage of the battery cell when it is in a recovery state after application of a stimulus (e.g., discharging or charging the battery). The measured voltage of the battery cell in the recovery state is then used to generate a characterization of the battery cell. The characterization may be used, for example, to match the battery cell with one or more similar battery cells to be coupled in a battery pack. In another example, the characterization may be used to verify authenticity of the battery cell.
