Abstract: An optical mouse has an image sensor (12) providing image data via an ADC (14) to a correlation circuit (16) and a motion estimation circuit (18) to provide output signals representative of mouse motion. The output signals are disabled when the mouse is lifted away from the working surface. This is achieved by summing each frame, after filtering in a high-pass filter (22), in a summer (26) to provide a single value, and comparing this with a threshold. If the filtered and summed value exceeds the threshold, this indicates that the image contains in-focus objects, and thus that the mouse is on the working surface.

Abstract: A method of forming a sensor is provided, together with a sensor formed according to the method. Photoresist material is deposited on a surface of the sensor, and is then patterned and etched to form an array of microlens structures. The structures are spaced close together in a predetermined pattern, so that when a reflow process is performed, the structures melt and coalesce to form a barrier, which defines a region which is suitable for constraining or channelling the flow of reagent and analyte samples used in bio-optical sensors.

Abstract: A bio-optical sensor has a surface provided with an array of sensing pixels (10) and calibration pixels (12) which are arranged in an interleaved fashion. The pixels (10,12) may be interleaved 1:1, or may be arranged in interleaved blocks, a preferred block size being between 20 and 30 pixels.

Abstract: An optical pointing device is described in which the power consumption is minimised by introducing a variable frame rate controller. Frame rate can be varied through analogue means by way of varying the reference current or through digital means by varying the length of time between successive frames. The variable frame rate controller can accept input from various measurements such as velocity of the device or spatial frequency of the surface on which the device is situated.
