摘要： A system for identifying a characteristic of a printing media includes a light source module that has a light emitting diode (LED) and an aspheric lens and a light detection module that has a photodetector and an aspheric lens. The light source module and light detection module are oriented with respect to a printing media such that the focusing points of the respective aspheric lenses are located at a common position on the printing media. The system differentiates between printing media types by applying light to the surface of the printing media and measuring the light that is reflected from the surface.

摘要： An apparatus having a die, a carrier, and a plurality of shielding wires. The die has a top surface through which EMI is received. The carrier has a first surface on which the die is mounted by attaching the die to the first surface using a surface of the die other than the top surface. The carrier also includes a plurality of electrical traces, the die being connected to two of the traces. The shielding wires cross the top surface of the die and are connected to a shielding trace in the carrier. The shielding trace is held at a constant potential. The shielding wires are positioned such that the EMI received by the die is reduced below the level that would be received without the shielding wires. The die could include a light detector.

摘要： A remote control (RC) receiver device and an ambient light photosensor (ALPS) device are mounted on a single mounting device (e.g., printed circuit board) such that they are part of a single composite assembly. This reduces the amount of space that is needed in electronic devices that incorporate both RC receiver devices and ALPS devices. In addition, by implementing both devices in a single composite assembly, costs associated with manufacturing, assembly and shipping can be reduced. Because the RC receiver device and the ALPS device operate on light of different wavelengths, the composite assembly includes filtering mechanisms that prevent undesired wavelengths of light from impinging on the photodiode of the RC receiver device and on the photosensor of the ALPS device.

摘要： An optical proximity sensor is provided that comprises an infrared light emitter an infrared light detector, a first molded optically transmissive infrared light pass component disposed over and covering the light emitter and a second molded optically transmissive infrared light pass component disposed over and covering the light detector. Located in-between the light emitter and the first molded optically transmissive infrared light pass component, and the light detector and the second molded optically transmissive infrared light pass component is a substantially optically non-transmissive infrared light barrier component. The infrared light barrier component substantially attenuates or blocks the transmission of undesired direct, scattered or reflected light between the light emitter and the light detector, and thereby minimizes optical crosstalk and interference between the light emitter and the light detector.

摘要： A transceiver having a light source die, a photodetector die and a substrate is disclosed. The substrate has a first well in which the light source die is mounted and a second well in which the photodetector die is mounted. The substrate has a reflective surface which blocks light leaving the light source from reaching the photodetector unless the light is reflected by an object external to the transceiver. The reflecting surface of the second well in the substrate is shaped to concentrate light received from outside the transceiver onto the photodetector, and in one aspect of the invention it comprises a non-imaging optical element. The light source is powered by applying a potential between first and second contacts on the light source die. A signal is generated between first and second contacts on the photodetector die in response to illumination of the photodetector die.
