摘要： A strain wave motor comprises a flexible spline that is prevented from rotating, and a rotatable cylindrical spline. The splines have annular geared surfaces, and are placed coaxially so that the geared surfaces mesh on distortion of the flexible spine. The two geared surfaces have a different number of teeth. Plural shape memory alloy wires distort the flexible spline at different angular positions so as to cause the geared surfaces to mesh and are driven by drive currents having waveforms causing the geared surfaces to mesh at one or more angular locations that move progressively around the cylindrical spline. That drives rotation of the cylindrical spline.

摘要： A haptic assembly comprises a chassis, a mass movably supported on the chassis; and at least one SMA actuator wire arranged, on contraction, to move the mass relative to the chassis. SMA provides actuation with a relatively large force which provides an improved haptic effect. A trigger element releases a retention element holding the mass against a resilient element loaded by the SMA. Drive signal powers may be controlled using resistance-based closed-loop control to allow shaping of the haptic waveform. Alternatively, the degree of movement may be increased by using a drive signal having sufficient power during an initial period that the mass achieves a sufficient velocity to cause the SMA actuator wire to go slack. A secondary actuator arrangement may be mounted on said mass to additionally generate vibrational movement.

摘要： Characteristics of polarizable particles in a fluid are detected using an optical cavity comprising opposed optical reflectors containing the fluid. A particle is introduced through the fluid into the optical cavity. The particle may be transiently in the cavity or optically trapped. The optical cavity containing the particle is illuminated with light that excites resonance of an optical mode of the optical cavity that is affected by the particle. A measurement of a parameter of the excited resonance is derived, for example while tuning through the resonance. Repeated measurements may be used to derive a measure of a characteristic of the particle that is dependent on the motion of the particle in the optical cavity.

摘要： An elongate component such as a drill string of drill pipes connected by joint sections inside a bore is sensed using at least one set of electromagnetic coils, the coils within the set being arranged at different angular positions around the bore facing the bore. There may be at least two sets of coils separated along the axial direction of the bore. Electrical oscillations are generated in the coils to produce oscillating electromagnetic fields that interact with the contents of the bore. A parameter of the electrical oscillations generated in each coil is detected. The detected parameters may be used to derive both (1) a measure of the axial position along the bore, and (2) a measure of the lateral position. The detected parameters may be used to derive a measure of electromagnetic properties of the contents of the pipe in a region adjacent each coil, thereby imaging the contents of the pipe.

摘要： A camera assembly comprises a lens assembly (20) supported on a support structure (4), wherein the lens assembly includes an autofocus actuator arrangement (24) and the camera assembly includes an optical image stabilization assembly (40) arranged to move the lens assembly in a plane perpendicular to the optical axis. A flexible printed circuit tape (103) connected between the support structure (4) and the lens assembly (20) and providing an electrical connection to the autofocus actuator arrangement (24) is bent around a comer, thereby allowing the flexible printed circuit tape (103) to accommodate the motion of the lens assembly perpendicular to the optical axis. A crimp plate (62) connected to the lens assembly which crimps shape memory alloy wires (80) has features (63) extending out of the plane of the crimp plate for reducing flexibility. At least part of the optical image stabilzation assembly overlaps the lens assembly in the direction along the optical axis, thereby reducing the height of the camera assembly.

摘要： An optoelectronic device has a layered construction, comprising a base layer, a first conductive layer, a photoactive layer and a second conductive layer. Plural separation channels extending through the photoactive layer and the first conductive layer separate the photoactive layer into photoactive regions, and insulator material extends through the respective separation channels to the base layer. Between adjacent photoactive regions, electrical connectors extend inside the lateral extent of the insulator material between a surface of a second electrode that is in electrical contact with one photoactive region to an opposing surface of a first electrode that is in electrical contact with the other photoactive region. By forming the electrical connectors extend inside the lateral extent of the insulator material, the overall size of the connection is minimised.

摘要： A semiconductor detector device (10) comprises a layer of semiconductor material (12) for generating charge in response to an input event and an array of pixels (11) for collecting charge. Tracks (10 - 50; 01 - 05) are connected to the pixels to supply signals representing the collected charge to a reader circuit. The pixels are grouped into sets, all the pixels within a set being connected to the same track, the sets of pixels being interwoven so that so that any group of n adjacent pixels capable of collecting charge generated by a single input event is connected to a combination of n tracks that is unique to the group of pixels, where n has a value of one of 2, 3 or 4. This allows detection of position of the area of charge collection (22) on the basis of temporally coincident signals on a combination of at least n tracks.
