摘要： A method for operating an optical sensing device having a light source and a photodetector device with at least one photosensitive element. A surface portion is illuminated with radiation by the light source and the radiation reflected from the illuminated surface portion is detected with a photosensitive element. While said surface portion is being illuminated, an output signal of the photosensitive element over time is integrated, the output signal integration level is compared with a first integration reference level during integration; the integration step is interrupted if the output signal integration level has reached the first integration reference level, or the comparison step is repeated until a first integration period has elapsed if the output signal integration level has not reached the first integration reference level.

摘要： The optoelectronic module includes a photoreceptor circuit for picking up light from a light source by reflection on an external surface. The photoreceptor circuit and the light source circuit are mounted on a substrate, and contact pads of the circuits are electrically connected to pads of the substrate. The substrate pads are connected to conductive paths of the substrate. The flexible substrate includes a first portion on which the photoreceptor circuit and light source circuit are mounted and electrically connected, a second portion including electrical connection terminals and a connecting portion between the first portion and the second portion. This connecting portion connects some conductive paths of the first portion to the connection terminals of the second portion. The connecting portion allows the height and/or spacing of the second portion to be adjusted relative to the first portion when the module is mounted, particularly in a computer mouse.

摘要： The method of making an optoelectronic module (10, 20), which includes a first light source circuit (5) and a second photoreceptor circuit (6) for picking up light from the first light source circuit reflected on an external surface. A first moulding (20) with an encapsulation material is made on one part of a lead frame (10) having several conductive paths (12) and an external frame (11) connecting all of the conductive paths. A first light source circuit (5) is placed on one portion of a first conductive path (13) of the lead frame that is not covered by the first moulding. A second photoreceptor circuit (6) is placed on one portion of a second conductive path (14) of the lead frame not covered by the first moulding. A through opening (21) is also made in the first moulding (20) between the external frame (11) and the location of the first light source circuit (5) to give access to the first connecting path (13) and to a third connecting path (15) for the first light source circuit. The contact pads of the first and second circuits (5, 6) are connected by metal wires (25) to corresponding uncovered pads of certain connecting paths (12) of the lead frame (10). The first and third connecting paths (13, 15) are then cut through the through opening (21) of the first moulding (20) in order to insulate electrically the first light source circuit (5) from the external parts. The light source circuit is thus protected from any electrostatic discharge. A second moulding can then be made on the first moulding (20) in order to close the through opening and obtain first and second apertures on the first and second circuits (5, 6) for the passage of light.

摘要： The optoelectronic circuit includes a photoreceptor (1) made in a silicon semiconductor substrate (4), and a monomode VCSEL laser diode (2) made in a gallium arsenide substrate. The photoreceptor includes at least one photosensitive area with a pixel array for picking up light and an area with a control and processing unit for the signals supplied by the pixels. The laser diode is mounted and electrically connected directly on one part of the photoreceptor. The laser diode is connected by a conductive terminal (12) to a first contact pad (3) at the bottom of a cavity (13) made through a passivation layer (5) of the photoreceptor. An electrode (17) on the top of the diode is connected by a metal wire (15) to a second contact pad (3) of the photoreceptor. The photoreceptor controls the diode directly via the electrode and the conductive terminal to generate a laser beam (L).
