Abstract

Far field devices typically rely on audio only for enabling user interaction and involve only audio processing. Adding a vision-based modality can greatly improve the user interface of far field devices to make them more natural to the user. For instance, users can look at the device to interact with it rather than having to repeatedly utter a wakeword. Vision can also be used to assist audio processing, such as to improve the beamformer. For instance, vision can be used for direction of arrival estimation. Combining vision and audio can greatly enhance the user interface and performance of far field devices.

Abstract

Digital isolators operable in multiple power modes are described. The digital isolators include a low power mode, in which some circuitry of the isolator operates in a lower power state than in other mode(s) of operation or may be deactivated, and in which data communication across the isolator is not permitted. The isolator may wake from the low power mode in response to a detected event or may periodically wake. Circuitry on one side of the isolator may dictate when and how the isolator wakes from a lower power mode.

Abstract

Techniques to improve the detection and mitigation of synchronous and asynchronous interference in radar signals. The corrupted received signals can be processed to reduce the effect of interference, while preserving existing targets. Various can use a two-step approach to (1) detect and mask the corrupted samples, and (2) recover the masked-out samples. The recovery step enforces sparsity of the existing targets and prevents target smearing, which is a common problem after interference mitigation. The sparsity enforcing recovery step can preserve small targets while successfully rejecting interference. The techniques do not require any prior knowledge of the parameters of the interfering radar.

Abstract

Apparatus and methods for shielded-gate trench power MOSFETs are disclosed herein. The power MOSFETs are fabricated using a self-aligned gate poly silicide to achieve low gate resistance. Accordingly, the power MOSFETs can be used in high speed applications operating with fast transistor switching speeds. Moreover, the self-aligned gate poly silicide processing can be achieved in relatively few processing steps, and thus can avoid the cost and/or complexity associated with conventional silicidation techniques for trench power MOSFETs. In particular, silicidation can include applying a silicide that is self-aligned to a gate oxide without an additional mask.

Abstract

Detection points may be first observed over multiple radar frames. The observed detection points, which form the tracklets, can be used to form a segmentation of the present radar frame by associating the tracklats to at least one object-track, which represents at least one object based on at least one feature-parameter. Segmentation results from tracking of detection points over multiple radar frames (viz. utilizing tracking information) which is used for associating detection points to objects (segmentation-by-tracking). A two-level tracking approach can be implemented, in which for a present radar frame, (new) detection points are associated to tracklets, which may be seen as a first level, and then the tracklets are associated to object-tracks, which may be seen as a second level.

Abstract

Battery monitoring techniques, which consume low amounts of power, are described herein. The battery monitoring techniques can be used when the host device (e.g., electric vehicle) is not operating, thus providing a time to use low power techniques. Measurement devices can measure system parameters when a host processor is off or in a low power mode using a heartbeat (HB) sequencing technique. Based on the HB message, the host processor can be alerted and awakened when a fault is detected.

Abstract

Several current sensing techniques are described that may be used to obtain an accurate current signal, which may help to achieve the best performance with a trans-inductor voltage regulator (TLVR) topology. The techniques may have the coupling effect from the secondary side included, so the current sensing signal is accurate for the regulation and other functions related to the current signal. The current sensing techniques may have more accurate gain and phase information in the middle frequency and high frequency ranges. The coupling effect from the secondary side may be well represented in the current sensing signal. The advantages of TLVR topology may be enhanced with accurate current information.

The geometry of the miniaturized design causes the signals reflected from the calibration device back to the ToF imager to have essentially the same time-of-flight. The design of the calibration device prevents the modulated emissions from leaking out to the environment.

Abstract

Aspects of the present disclosure include isolating a target scene object from multiple images of a time-of-flight (TOF) sensor. Multiple images from a TOF sensor can be transformed into multiple three-dimensional (3D) point clouds. In each of the multiple 3D point clouds, one or more large planes having a minimal threshold size can be identified. A common 3D point cloud can be generated by aligning rotated and translated point clouds corresponding to at least a portion of the multiple 3D point clouds. The common 3D point cloud can be rotated and translated to have one of one or more large planes identified as a ground plane within a common coordinate system of the common 3D point cloud, and a target object can be isolated.

Abstract

Aspects of the present disclosure include aligning multiple three-dimensional (3D) point clouds into a common 3D point cloud. A first subset of points within a first 3D point cloud generated from one time-of-flight (TOF) view can be associated with a second subset of points within a second 3D point cloud generated from another TOF view based on each point in the first subset of points having a threshold correspondence to a unique counterpart point in the second subset of points. The first subset of points and the second subset of points can be refined, and a relative rotation and translation between the first 3D point cloud and the second 3D point cloud can be determined. The first 3D point cloud and the second 3D point cloud can be aligned within a common coordinate system based on the relative rotation and translation.

Abstract

Device for improving an optical detecting smoke apparatus and implementing thereof. Apparatus and methods for detecting the presence of smoke in a small, long-lasting smoke detector are disclosed. Specifically, the present disclosure shows how to build one or more optimized blocking members in a smoke detector to augment signal to noise ratio. This is performed while keeping the reflections from the housing structure to a very low value while satisfying all the other peripheral needs of fast response to smoke and preventing ambient light. This allows very small measurements of light scattering of the smoke particles to be reliable in a device resistant to the negative effects of dust. In particular, geometrical optical elements, e.g., cap and optical deflection elements, are disclosed.

Abstract

Multiple transmit and receive channels in a communication transceiver may be dynamically configured using corresponding channel registers. In order to support fast frequency hopping, arbitrary sample rate change or profile switching, the present disclosure proposes a profile-based direct memory access (PDMA) that can be used to transfer data from a memory and program specific profile registers in a randomly accessed addressing manner. PDMAs can offload the system processor from reprogramming many system registers based on external or internal events in a multi channels communication system. Furthermore, a PDMA based DMA controller is proposed to configure the fast frequency hopping registers of the transceiver based on PDMA.
