摘要： A linear motor comprising a linearly-extensive stator (1) supporting a translator (2), the stator providing in operation a squeezing force across the translator in a direction approximately orthogonal to the line of the stator, and the translator either having along its movement direction a slightly tapered profile or being mounted on the stator by force-transmitting bearings (3) that when so squeezed deform to become slightly tapered, the effect being to produce a resultant force on the translator that is along the line of the stator. The utilisation of a resilient toroidal bearing member (103) fitted inside and co-axially with a tubular passageway (108) in an outer, sleeve-like bearing body (101) through which an inner bearing body (102) is free to slide. The inner body is then fitted through the toroid, all three components thus being co-axially aligned. The resultant bearing can be of extremely low mass, of very low cost, and with strong radial alignment (centering) force, very low resistance to axial motion, almost unlimited movement in the axial direction.

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： The invention relates to sonic steerable antennae and their use to achieve a variety of effects. The invention comprises 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, focus beam or a simulated origin. Further, “anti-sound” may be directed so as to create nulls (quiet spots) in an already existing sound field. The input signal replicas may also be modified in way which changes their amplitude or they may be filtered to provide the desired delaying. Reflective or resonant surfaces may be used to achieve a surround sound effect, a microphone may be located in front of an array of loudspeakers, beams of light may be used to identify the present focal position, a limiting device may be used to ensure that clipping or distortion is reduced when more than one input signal is output by the same device and the concept of beam directivity may be used to achieve input nulls or beams in a microphone made up of an array of input transducers. Further, sound field shaping information may be associated with an audio signal to be broadcast.

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： A directional microphone system includes an ultrasonic emitter and receiver. The emitter directs a beam of ultrasound at the audio source with sufficient intensity that non-linear air effects cause non-linear interactions between the ultrasonic sound and the source's sonic sound. Ultrasonic frequency-mired sounds are thereby generated and these are received by the ultrasonic receiver. Signal-processing is carried out on the received signals to strip out the audio signals. The emitter and receiver may be co-located and the emitted beam may be focussed at the location of the audio source. The receiver may also be directional acid focussable. The directional microphone system may be very small and yet highly directional at sonic including low audible frequencies.
