摘要： A thermal imaging device includes detector pixels A, B, C provided by a pyroelectric layer 1 arranged between electrode structures 3 and 4. A photoconductive layer 7 is provided between the electrode structure 5 and a further electrode structure 9. The device also includes an illumination source 11 for illuminating the photoconductive layer 7 for enabling pyroelectric charge developed by the detector pixels A, B, C to be optically addressed via the electrode structure 9. Optical addressing of the detector pixels obviates the need for solid state switching connections to each pixel, providing an imaging device readily capable of large scale fabrication.

摘要： An infrared imaging arrangement using a chopping device for periodically blocking exposure of an array of detector elements responsive to infrared energy by using a plurality of individually-mounted cells. There is a non-reciprocating rotary mechanism used for moving the cells substantially orthogonal to the array in such a manner that constant orientation of the cells is maintained in order to expose the array to energy via the cells. Since the cells orientation is maintained, the shift of energy relative to the array increases the arrays ability to resolve spatially sources of energy. There is also an infrared blocking piece used for blocking the infrared energy from impinging on the array.

摘要： A thermal imaging device includes an array of pyroelectric detector elements, supported by an array of pillars, the pillars also being effective to enable the passage of electrical signals between the detector elements and an electrical signal processing means. Each pillar is separated from a respective detector electrode by an elongate electrically conductive strip. The device includes areas of infra-red absorbant material effective to conduct heat from non-electroded parts of the device into adjacent pyroelectric detector elements.

摘要： An infrared detector comprises an array of detector elements (2) of the type having a layer of pyroelectric material (4)sandwiched between upper and lower electrodes (6,8) and separated along each edge by separations (16). The electrical sheet resistance of the upper electrode array (6) is reduced by forming gold rims (24) on the edges of the electrodes (6) around the periphery of each separation (16).

摘要： Noise reduction circuitry for a communication apparatus can apply different noise reduction transfer functions, depending on whether a listening device is connected to the apparatus. If no listening device is connected, the noise reduction transfer function can be adapted for use with microphones (12) and speakers (28) that form an integral part of the communication apparatus, which may be a cellular telephone. If a listening device is connected, the noise reduction transfer function can be adapted for use with microphones (12) and speakers (28) that form a part of the listening device. This allows the noise reduction circuitry to provide improved noise reduction performance.

摘要： The invention provides a noise reduction control system for an ear-worn speaker-carrying device (“ESD”). The system is configured to sense ambient noise and to develop electrical signals which can be used to reduce the amount of said ambient noise audible to a wearer of the ESD. The system sets a plurality of predetermined and discrete noise reduction levels and automatically responds to at least one controlling event, outside the control of the wearer, to set the degree of noise reduction to one of those discrete levels. Typically, the system inverts and filters the electrical signals relating to ambient noise and feeds the inverted and filtered signals to the speaker of the ESD in time for the speaker to generate sounds capable of interfering destructively with the ambient noise.

摘要： A method of processing a single channel audio signal to provide an audio source signal having left and right channels corresponding to a sound source at a given direction in space, includes performing a binaural synthesis introducing a time delay between the channels corresponding to the inter-aural time difference for a signal coming from said given direction, and controlling the left ear signal magnitude and the right ear signal magnitude to be at respective values. These values are determined by choosing a position for the sound source relative to the position of the head of a listener in use, calculating the distance from the chosen position of the sound source to respective ears of the listener, and determining the corresponding left ear signal magnitude and right ear signal magnitude using the inverse square law dependence of sound intensity with distance to provide cues for perception of the distance of said sound source in use.

摘要： A gas sensitive device, for example a gas sensitive MISFET (FIGS. 1 to 3) has a gas-sensitive electrode (15) comprising a catalytically active metal (e.g. Pt or Pd) and a non-metallic material (e.g. SiO.sub.2) mixed with, or deposited at an exposed surface of, the metal to modify the catalytic activity of the metal. The electrode has an enhanced sensitivity to, and selectivity of, certain gases. The composite material is applicable to other gas-sensitive devices, e.g. an optical fibre gas sensor.
