  • Patent number: 10586446
    Abstract: Disclosed is an identification system to improve safety on roads and allow for the driver or for the vehicle itself, if it is autonomous or semi-autonomous, to have readable and useful information about road signs, roadways, and adjacent roadway information. The disclosed identification system comprises a marker with marker communication information that can be read by a vehicle information system to provide information to the vehicle. Information that the marker communication information may convey would allow the vehicle information system to detect or recognize, or both detect and recognize critical road sign, roadway information, and adjacent roadway information. Then, the vehicle information system could respond to the information received from the marker communication information.
    Type: Grant

  • Patent number: 5734156
    Abstract: An optical device assembly includes a planar optical filter and a planar sensor having an optically active area. The optical filter and the sensor are joined together with a gap therebetween by a standoff structure extending between the optical filter and the sensor. The standoff structure is positioned at a location outside of the optically active area of the planar sensor. The standoff structure includes a standoff element, a first bonding element between the standoff and the filter, and a second bonding element between the standoff and the sensor. The two bonding elements each preferably comprise a cold-weldable indium bump. If the standoff structure, the filter, or the sensor is made of a material to which indium does not readily cold weld, a bonding pad of a material such as titanium/nickel can be inserted to facilitate the cold welding.

  • Patent number: 5689106
    Abstract: An optical device assembly includes a planar optical filter and a planar sensor having an optically active area. The optical filter and the sensor are joined together with a gap therebetween by a metallic bump extending between the optical filter and the sensor. The metallic bump, which is preferably indium, is positioned at a location outside of the optically active area of the planar sensor. The metallic bump is preferably formed by vapor depositing an indium subbump on the optical filter and another indium subbump on the planar sensor, in each case outside of their optically active areas, and thereafter pressing the two subbumps together to complete the bonding.
