A mirror includes an electro-optic mirror subassembly, and a thin-profiled bezel attached around a perimeter of the electrochromic mirror subassembly. The electro-optic mirror subassembly is supported on a carrier by an adheringly bonded heater and foam tape in a laminar arrangement. The bezel may be bonded to an edge of the front surface of the front element of the electro-optic mirror subassembly, and/or may be bonded and/or interlockingly mechanically attached to an edge of the carrier. Alternatively, the bezel can be a strip of paint or thin coating material. The bezel can be molded in place, or can be pre-molded and elastically stretched to permit assembly. In one form, the bezel includes a laterally-extending fin that prevents seeing past the bezel into the inside of a mirror housing. In at least one embodiment, the assembly has no bezel or only a bezel on one edge.

A rearview assembly comprising a rearview element, a rearview element support assembly supporting the rearview element and a mount adjacent the housing. The mount is configured to connect the rearview assembly to a windshield. At least one of the rearview element support assembly and the mount comprises a crush bracket having at least two legs adapted to be compressed as a force strikes a front of the rearview element. The crush bracket can include at least one tab contacting a heat emitting component and/or an electrically conductive component of a circuit to provide a heat sink for the heat emitting component or a ground for the electrically conductive component, respectively.

A traffic system for alerting a driver of a vehicle to a traffic sign includes a sensor and a control unit. The sensor may be an image sensor and the control unit may comprise a graphic processing unit (GPU) to detect the optical flow of objects in the captured images so as to distinguish moving vehicles from non-moving objects. The speed of vehicles may be detected such that the system may (1) activate lights to warn a driver if he is traveling too fast or (2) display the speed to either the driver or a police officer. The system may also be implemented and used as a geographic border monitoring system.
摘要:
According to the present invention, a rearview mirror comprises a first substrate having a front surface and a rear surface, a reflective coating disposed on a surface of the first substrate, and an electronic circuit component secured to the rear surface of the first substrate. The mirror element may be an electrochromic mirror element comprising a transparent second substrate positioned in front of the first substrate. The electronic component secured to the rear surface may be a component of a drive circuit for the electrochromic mirror element. The rearview mirror element may further comprise electrically conductive tracings provided on the rear surface of the first substrate electrically coupled to the electrical component. The tracings may be used to electrically couple the drive circuit to the electrodes of the electrochromic mirror element. The tracings may be deposited on the rear surface using numerous methods including inkjet printing techniques.

A truss joist includes an upper chord, a lower chord and a series of links. The series of links connects the upper and lower chord and terminates in an end link which is attached to the lower chord and extends upwardly toward the terminal portion of the upper chord. An end bracket which partially surrounds the terminal portion of the upper chord includes a U-shaped channel which contacts the side and bottom surfaces of the upper chord. The U-shaped channel further comprises a pair of downwardly projecting legs for connectively receiving the flattened end portion of the end link. One embodiment of the end bracket lies directly upon the upper surface of a support member. Another embodiment is flush-mounted against the inner surface of the support member and has a horizontal flange which extends over the upper surface of the support member. Additional embodiments of the end bracket include adjustable bracket elements mounted below the U-shaped channel and on either side of the downwardly projecting legs. Since those adjustable end brackets are slidably connected to the end bracket, they allow the length of the truss joist to be adjusted. These adjustable bracket elements include flat end surfaces which permit them to be nailed to the inner surface of the support member and thereby assist in securing the end bracket to the support member.
摘要:
A system for automatically controlling continuously variable headlamps on a controlled vehicle includes an imaging system capable of determining lateral and elevational locations of headlamps from oncoming vehicles and tail lamps from leading vehicles. The system also includes a control unit that can acquire an image from in front of the controlled vehicle. The image covers a glare area including points at which drivers of oncoming and leading vehicles would perceive the headlamps to cause excessive glare. The image is processed to determine if at least one oncoming or leading vehicle is within the glare area. If at least one vehicle is within the glare area, the headlamp illumination range is reduced. Otherwise, the illumination range is set to full illumination range.
