摘要:
A remote controlled locking system employing a holographic window display, particularly adapted for vehicle use. The system includes a remotely-operated transmitter for transmitting locking and unlocking signals, and a locking mechanism that is locked and unlocked in response to the transmitted signals. The locking mechanism outputs a status signal or status signals, corresponding to at least one of the locking and unlocking signals. Control electronics process the status signals from the locking mechanism to provide control signals that are coupled to first and second light emitting members, such as LED arrays. The light emitting members produce light output signals in response to the control signals. First and second prism couplers are attached to a surface of a window and are optically coupled to the first and second light emitting members. First and second hologram decals that comprise the holographic window display are attached to the surface of the window and are responsive to the light output signals. The first and second hologram decals respectively display first and second visible messages indicative of whether the locking mechanism is locked and unlocked. If only one status message is to be displayed, then the second set of components is not required, namely the second light emitting member, second input coupler, and second image hologram decal.
摘要:
A power distribution and communication system includes nodes connected by power lines and communication links. The system receives power from one or more power sources. Each node contains at least one power port, data port and load port. Associated with each power port and load port is a port monitor for measuring current flowing into or out of the port and the voltage difference between the port outlet and ground, which measurements are passed to a processing element. The processing element and monitor analyze measured values to detect fault conditions. Upon fault condition detection, the port is disabled by opening a switch, disconnecting the port from the system voltage. The processing element receives power directly from the power line, thus receiving power from a live power line even if the associated power port is disabled allowing the processing element to enable a disabled node following a failure.
