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 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.

摘要： A loudspeaker has a digital input signal port connected to a digital interpolator to increase the effective sampling rate whose output is fed to a signal delay and magnitude detector after which the short-term dynamic range of the input signal is possibly reduced before application of a unary encoder which encodes the digital input signal into a plurality of unary signals which are then differentially delayed and pulse shaped before application to a plurality of substantially identical acoustic transducers via transducer drivers whose average power drive levels may be controlled by signals derived from the magnitude detector and from a human operator to alter the sound volume produced.

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.
