摘要： A miniature camera lens actuation apparatus comprises a support structure, a camera lens element supported on the support structure by a suspension system; and an SMA actuator connected between the support structure and the movable element to drive movement of the camera lens element. The control circuit may include a drive circuit and a sensor circuit which have separate electrical connections to the SMA actuator to reduce the impact of the resistance of the electrical connections on the sensing. The control circuit may vary the drive signal in response to a temperature signal indicative of the ambient temperature. An endstop limits movement to prevent extension of the SMA actuator in its unheated state beyond a maximum length which is at or below the length corresponding the local maximum resistance of the resistance-length curve. Control of position is effected using resistance of the SMA actuator as a measure of position. The control employs a ‘ratcheting’ method to prevent a failure condition and an initial calibration step to derive a range of target resistance values. In manufacture, the position of a lens holder is adjusted relative to a carrier to provide focussing on the image sensor of an image of an object at a distance in the range from infinity to the hyperfocal distance when the SMA actuator is heated to a predetermined temperature greater than ambient temperature.

摘要： A miniature camera lens actuation apparatus provides an auto-macro function in which a camera lens element has two focus positions. In one type of apparatus, a shape memory alloy actuator arranged to drive movement of the camera lens element relative to a support structure against an end-stop arranged to limit the movement. The shape memory alloy actuator is connected to one of the movable element and the support structure by a compliant connector. This limits the stresses on the shape memory alloy actuator and therefore increases its lifetime. In another type of apparatus, the suspension system supporting the movable element on the support structure provides the movable element with two stable positions along the movement direction.

摘要： An equivalent to the spatial separation either side of a nominal median plane that is inherent in a bimorph (with one piezoelectric layer on one side, and the second on the other side of the plane) is attained by structurally shaping the cross-section of a simple, single piezoelectric layer (11) such that it has a multiplicity of piezoelectric portions arranged in two generally-planar groups one either side of a median plane, so that any dimension change undergone by a portion on one side of that plane will tend to bend the whole device in the opposite direction to the same sense dimension change undergone by a portion on the other side of that plane. The simple, single layer acts as though it were a bimorph if elongate and beam-like, bending along its length, one end moving up/down, or back/forth, relative to the other but with any need for an internal, electrode.

摘要： The present invention combines a head-tracking system, for example a camera system typically used for user head and eye tracking, with a plurality of loudspeakers to as to enhance the audio experience of the user. The location of the user can be used to alter the audio signal sent to the plurality of loudspeakers to improve such functions as surround sound. In addition, the camera system can be used, when combined with an array of loudspeakers that can produce tight beams of sound, to direct different sound beams at different users, with virtually no crosstalk so as to allow users to experience different media from the same audio system, and which is tolerant of changed user positions. In addition, the camera system can aid setting up the array for real surround sound delivery, which bounces sound beams off wall. Cross-talk cancellation can additionally be used. The sound beams may represent 2-D or 3-D sound sources in real time. Sound beam parameters are adjusted to provide the listener with in impression of the 2-D or 3-D position and movement of sound-producing entities of audio-visual programme material in real-time. The beam parameters used include beam-direction, beam focal length, frequency response and gain. Such a Sound Projector producing a real-time representation of 3-D sound sources can be used alone or in conjunction with a video display, a television, a personal computer or a games console.

摘要： A loudspeaker comprises a sound generating element mounted on a support structure, and two rotary actuators I mounted at opposing edges of the sound generating element. The actuators are operable to drive motion of the sound generating element relative to the support structure including a component of rotation. The loudspeaker produces a greater sound output than if driven at one edge only, and is particularly suitable for use in a portable electronic device such as a mobile telephone, in which case the support structure may be a portion of the casing of the, device and the sound generating element maybe a transparent panel covering a display device.

摘要： The invention generally relates to a method and apparatus for taking an input signal, replicating it a number of times and modifying each of the replicas before routing them to respective output transducers such that a desired sound field is created. This sound field may comprise a directed beam, focused beam or a simulated origin. In a first aspect, delays are added to sound channels to remove the effects of different travelling distances. In a second aspect, a delay is added to a video signal to account for the delays added to the sound channels. In a third aspect, different window functions are applied to each channel to give improved flexibility of use. In a fourth aspect, a smaller extent of transducers is used top output high frequencies than are used to output low frequencies. An array having a larger density of transducers near the center is also provided. In a fifth aspect, a line of elongate transducers is provided to give good directivity in a plane. In a sixth aspect, sound beams are focused in front or behind surfaces to give different beam widths and simulated origins. In a seventh aspect, a camera is used to indicate where sound is directed.
