  • Patent number: 10190905
    Abstract: An optical sensor arrangement comprises an optical barrier which is placed between a light-emitting device and a photodetector. Herein the light-emitting device and the photodetector are arranged on a first plane and are covered by a cover. The photodetector exhibits an active zone. The optical barrier exhibits an extent along a first principal axis, which is pointing parallel to the line connecting the centers of the light-emitting device and the photodetector. Herein the extent is greater than a dimension of the active zone. The optical barrier is designed to block light emitted by the light-emitting device that otherwise would be reflected by the cover by means of specular reflection and would reach the photodetector. The optical barrier is designed to pass light emitted by the light-emitting device and scattered on or above an outer surface of the cover.

  • Patent number: 9528820
    Abstract: An optical proximity sensor often emits light, and detects the photons in the returned light signal. Because light can be reflected and scattered by cover glass and ink layer printed on the cover glass, optical crosstalk is a concern for the optical proximity sensors. In one embodiment, the present disclosure provides an optical proximity sensor including a linear polarizer to cover the photo detector, or a polarizer to cover the light emitting device, or two polarizers to cover both the photo detector and the light emitting device. The polarizer blocks the s-polarized light and only allows the p-polarized light to pass through. Because the scattered light is predominated by the s-polarization, the optical crosstalk may be reduced.

  • Publication number: 20060277129
    Abstract: In a system and method for obtaining financing to fund transaction settlements in a supply chain, the financing is obtained with a note, the proceeds of which are used to pay for purchase of one or more accounts receivable. The note is issued in one of the capital markets, and is secured by a substantially absolute obligation of only a single buyer to pay.

  • Patent number: 6842713
    Abstract: The present invention relates to a novel diagnostic radar data retrieval apparatus and method of using the same. One aspect of the present invention includes a portable unit that extracts and stores radar calibration data from radar specific hardware (via a 1553 communications bus) to a personal computer (PC) for diagnostic purposes. Another aspect of the present invention is a method wherein the calibration data stored in the RCCM device is downloaded to a computer, preferably a PC, with input and display software that receives the data from the RCCM device and processes the radar calibration data into tables for various types of analysis such as, but not limited to, troubleshooting purposes.
