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.

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： Reflection of light from a surface is sensed by emitting light from a light emitting diode and focusing the light using an aspherical emitter lens to illuminate a reflecting surface. Light reflected by the reflecting surface is focused onto a photodetector using an aspherical collector lens. The light emitting diode is displaced from the optical axis of the aspherical emitter lens and the photodetector is displaced from the optical axis of the aspherical collector lens.

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.
