Abstract

An improved capacitor is provided wherein the capacitor has an improved bond between the anode and anode wire. The anode comprises a pressed anode powder comprising a first density region and a second density region wherein the second density region has a higher density than the first density region. An anode wire extends into the second density region wherein the anode wire in the second density region is distorted by compression. This allows for better utilization of the metal powder surface area by allowing a lower bulk press density and lower sinter temperature while still achieving the necessary wire pull strength. In addition, this invention when utilized with deoxidation steps, results in sufficient wire pull strengths not possible otherwise.

Abstract

Electromechanical polymer (EMP) actuators are used to create haptic effects on a user interface deface, such as a keyboard. The keys of the keyboard may be embossed in a top layer to provide better key definition and to house the EMP actuator. Specifically, an EMP actuator is housed inside an embossed graphic layer that covers a key of the keyboard. Such a keyboard has a significant user interface value. For example, the embossed key provides the tactile effect of the presence of a key with edges, while allowing for the localized control of haptic vibrations. For such applications, an EMP transducer provides high strains, vibrations or both under control of an electric field. Furthermore, the EMP transducer can generate strong vibrations. When the frequency of the vibrations falls within the acoustic range, the EMP transducer can generate audible sound, thereby functioning as an audio speaker.

Abstract

An improved capacitor is provided wherein the capacitor has an improved bond between the anode and anode wire. The anode comprises a pressed anode powder comprising a first density region and a second density region wherein the second density region has a higher density than the first density region. An anode wire extends into the second density region wherein the anode wire in the second density region is distorted by compression. This allows for better utilization of the metal powder surface area by allowing a lower bulk press density and lower sinter temperature while still achieving the necessary wire pull strength. In addition, this invention when utilized with deoxidation steps, results in sufficient wire pull strengths not possible otherwise.

An MLCC with an identification mark consisting of non-active internal electrodes which can be used to determine chip orientation for mounting or reeling. This allows an MLCC with substantially similar width and thickness to be oriented with the electrodes in a preferred direction (either vertical or horizontal with respect to the board) that results in the minimum noise and vibration compared to other orientations. The presence of an identification mark can also allow for a means of preferentially orienting an MLCC which has an active area that is offset from the geometric center of the part.

Abstract

A catheter includes an electromechanical polymer (EMP) actuator disposed in a steerable tip at the distal end of the catheter. When activated, the EMP actuator deflects the steerable tip through an angle between 0 and 270 degrees, thus permitting the operator to steer the steerable tip through the vasculature. The steerable tip also has at least a first relatively stiff region and a second relatively flexible region, and the EMP actuator is provided next to the first relatively stiff region so that the steerable tip may toward the flexible region when activated. In one implementation, an external interface allows a user to select by name one of many sets of control signals, with each set of control signals being signals calibrated for configuring the catheter to mimic a known catheter.

Abstract

An improved capacitor and a method for forming an improved capacitor is detailed. The method comprises forming a tantalum anode from a tantalum powder with a powder charge of no more than 40,000 μC/g; forming a dielectric on the anode by anodization at a formation voltage of no more than 100 V; and forming a conductive polymeric cathode on the dielectric wherein the capacitor has a breakdown voltage higher than the formation voltage.

Abstract

A stacked MLCC capacitor is provided wherein the capacitor stack comprises multilayered ceramic capacitors wherein each multilayered ceramic capacitor comprises first electrodes and second electrodes in an alternating stack with a dielectric between each first electrode and each adjacent second electrode. The first electrodes terminate at a first side and the second electrodes second side. A first transient liquid phase sintering conductive layer is the first side and in electrical contact with each first electrode; and a second transient liquid phase sintering conductive layer is on the second side and in electrical contact with each second electrode.

Abstract

An electromechanical polymer (EMP) transducer may include (a) one or more EMP layers each having a first operating characteristic; and (b) one or more EMP layers each having a second operating characteristic different from the first operating characteristic. The EMP transducer may include at least two EMP layers that are activated independently, and one or more EMP layers being configured to be a sensing layer. The sensing layer may sensitive to one or both of the operating characteristics (e.g., temperature, strain, pressure and their respective rates of change). Other operating characteristic may include resin type, modulus, film thicknesses, degrees of deformations, operating temperature ranges, a stretching ratio of the EMP layers, metallization patterns of electrodes, arrangements of active and inactive EMP layers, arrangements of irradiated EMP layers, arrangements of EMP layers acting as sensors, and arrangements of inactive layers of various degrees of stiffness.
