摘要： A charge measurement circuit (20) includes a charge sensitive amplifier (40) which holds the input (42) at a constant voltage. A compensation circuit (72, 74, 76, 80) enables a current to be supplied to or drained from a charge supplying circuit (32). This current is selected such that any voltage mismatch between the output of the supplying circuit (32) and the input (42) of the measurement circuit (20) does not result in a charge flow which causes errors in the measured signal.

摘要： Audio signal reproduction apparatus, for example an in-car entertainment system comprises a number of audio signal sources (I-I to I-N) which are selected by means of a selector (2) and fed to an AGC circuit (4) before being applied to an amplifier (6) and loudspeaker (7). The AGC circuit (4) comprises an amplitude analyser (42) and a low pass filter (43) to produce an output signal (44) which controls the gain of an amplifier (41). The arrangement is such that the AGC circuit only causes a gain change when the audio signal lies outside a predetermined amplitude band for a given minimum time period. Thus only long "too loud" or "too soft" passages cause a gain change and transients pass through the arrangement without causing a gain change.
摘要翻译：音频信号再现装置，例如车载娱乐系统包括多个音频信号源（II至IN），它们通过选择器（2）选择并被馈送到AGC电路（4），然后被施加到一个放大器（6）和扬声器（7）。 AGC电路（4）包括幅度分析器（42）和低通滤波器（43），以产生控制放大器（41）的增益的输出信号（44）。这种布置使得当音频信号在给定的最小时间周期之前位于预定幅度频带之外时，AGC电路仅引起增益改变。因此，只有长时间的“太大”或“太软”通道会导致增益变化和瞬变通过安排而不会导致增益变化。

摘要： A flat panel display or image sensor or a data store or memory device, or other type of large area electronic device, particularly but not exclusively with thin-film circuitry, comprises an array of device elements (8) which are arranged in rows (N...) and columns (M...) with the device elements (8) in each pair of neighbouring columns (M, M+1) sharing a column conductor (11). The device elements (8) are coupled to their associated row conductor (21) via a first switching element (S1). In each pair (M, M+1) of neighbouring columns, the device elements (8) share a column conductor (11). In accordance with the present invention, each device element of a row (N) in one column (M) of each pair is coupled via a respective second switching element (S2) to one reference conductor (1), while each device element (8) of the same row (N) in the other column (M+1) of the pair is coupled via a respective second switching element (S2) to another reference conductor (2). The reference conductors (1 and 2) function as enabling lines, which extend throughout the array for selecting their respective device elements (8). The present invention permits the device elements (8) in pairs of neighbouring columns to share a column conductor (11), without the necessity for the device elements (8) to have opposite orientations, and without the need for the switching elements (S1, S2) to be of opposite conductivity types or to be driven with opposite polarity pulses. The switching elements (S1, S2) can be fabricated with less processing steps, as thin-film diodes. Furthermore, the device elements (8) may share both a column conductor (11) and a row conductor (21) so as to reduce the numbers of both column conductors and row conductors for the array. Thus, the device elements (8) may be organised in groups of four (10A, 10B, 10C, 10D) in pairs of neighbouring columns and rows, with four separate reference conductors (1, 2, 3, 4) extending throughout the array.

摘要： A multiplexer circuit comprises switches (26 or 260) each having a hold portion (120 or 1200) and driving portion (110 or 1100) for providing a hold voltage or a select voltage to an output (14). If all control inputs (28A or 280A) are at a first level, then the output has the select voltage, whereas if one input (28A) is at a second level, the output has the hold voltage. The switches (26) may be integrated onto the substrate of a diode-based array of electrical elements, for example image sensing pixels. In this case, the output (14) comprises a row conductor for a row of such pixels.

摘要： A light pen input system comprises a light sensing device (10) having a row and column array of light sensing elements (14) over which a light pen (12) is moved to write in information, e.g., for display on a display screen, the light beam emitted by the pen producing a light spot (20) on the array which covers, and is sensed by, a plurality of adjacent elements and which, with the beam directed perpendicularly to the array, is substantially non-circular in shape, having dimensions in two directions over the array which differ one another. Rotation of the pen around its axis is then detectable, providing additional functionality. An elongated light spot, e.g., elliptical, rectangular or triangular, provides further capabilities in enabling the width of a written stroke to be varied by twisting the pen.

摘要： An image sensor comprises an image capturing device (10) and a lens arrangement (20, 30, 40), positioned between an area to be imaged and the image capturing device (10). The lens arrangement includes at least one array (40) of spaced lens elements (42) for transmitting light from a portion of the area to be imaged to a portion of the device (10). Light emitting means (46), for example electroluminescent strips, are disposed in or over the spacing between the lens elements (42). This provides a compact optical focusing and illumination system. A colour imaging system may be provided using discrete coloured light sources.

摘要： An array of electrical elements is arranged in rows and columns, signals being read out from the column conductors. Each column has a multiplexer switch so that signals from a number of columns may be switched to a common output. Each multiplexer switch comprises a diode bridge (36-39) having an input (60) and an output (34). Current is supplied to the diode bridge through a supply diode (52) and drained from the bridge through a drain diode (54), for controlling the switching of the bridge. The all-diode switch may be integrated on the substrate of the array and has a substantially linear switching response.
