  • Patent number: 8446475
    Abstract: 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.

  • Publication number: 20130121515
    Abstract: 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.

  • Patent number: 8325941
    Abstract: 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.

  • Patent number: 8073320
    Abstract: 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.

  • Publication number: 20110129101
    Abstract: 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.

  • Publication number: 20090161880
    Abstract: 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.

  • Publication number: 20070223763
    Abstract: A loudspeaker comprises a region devoid of electroacoustic transducers and at least two groups of electroacoustic transducers at the periphery of the region. Each of the groups is configured to produce a different sound field representative of an audio signal and each of the groups comprise a different set of transducers. This allows a more compact loudspeaker to be provided because the transducers can be located around the periphery of a visual display screen. Sound quality is not compromised because groups of transducers forming a subset of the totality of transducers are used for each sound signal, thereby avoiding alias beams.

  • Publication number: 20070216796
    Abstract: A digital camera comprises an image sensor for capturing an image, a lens arrangement arranged to focus light onto the image sensor and providing a variable focus, and a memory for storing images captured by the image sensor. Focusing is achieved by a series of images having differing focus provided by the lens arrangement being captured by the image sensor and stored in the memory. Analysis of the images stored in the memory to determine the quality of the focus of the images is used to derive an in-focus image from the series of images. This avoids the complication of employing autofocusing control of the lens arrangement. Movement of the lens arrangement may be driven by movement of a button operable by a user which avoids the need for an actuator for the lens arrangement.

  • Publication number: 20070177860
    Abstract: A camera comprises an image sensor arranged to generate an image signal, and a lens arrangement, which focuses an image onto the image sensor, the focus being variable in accordance with a control signal applied thereto. In the case that a piezoelectric actuator experiencing hysteresis is used to drive movement of the lens arrangement to vary the focus of the image, autofocusing is achieved by applying a control signal to the piezoelectric actuator with a value at an extreme of a predetermined range and subsequently changing the control signal monotonically across the predetermined range to determine a position at which the focus quality is at an acceptable level. Thus, this position may be returned to despite the hysteresis.
