Abstract:
A street lighting fixture and street lamp used in street lighting containing an accelerometer that is used to detect and characterize acceleration events on a street lighting fixture. The accelerometer readings may be combined with GPS technology to determine a relocation of the street lighting fixture.
Abstract:
Systems and methods for communicating ultrasound probe location and image information are provided. One system includes an ultrasound device coupled with an ultrasound probe and configured to acquire ultrasound images of a subject. The ultrasound imaging system also includes at least one camera configured to acquire (i) scene information including ultrasound imagery of the ultrasound probe with the subject during an image scan and (ii) ancillary probe data. The ultrasound imaging system further includes a processor configured to receive the ultrasound images and the ancillary probe data and a multiplexing unit configured to receive (i) the ultrasound images and ancillary probe data from the processor and (ii) the scene information from the camera, wherein the multiplexing unit is further configured to associate in time the ultrasound images, ancillary probe data and scene information. The ultrasound imaging system additionally includes a communication device.
Abstract:
A system and method for a lighting control system to control street lighting fixtures using modified geometric harmonic modulation for communications over a powerline. At least some of the lighting fixtures have another communications capability that enables RF communications. The communications may by messages be sent to the lighting fixtures to read RF enabled meters.
Abstract:
Simple yet robust active optical connectors are provided comprising: (a) a first connecting module configured to be joined to a first fiber optic cable, the first connecting module being configured to receive a first transmission signal from a signal carrying fiber of the first fiber optic cable and to actively convert the first transmission signal into an optical connection signal; and (b) a second connecting module configured to be joined to a second fiber optic cable, the second connecting module being configured to receive the optical connection signal and to propagate a second transmission signal within a signal carrying fiber of the second fiber optic cable; wherein the first connecting module comprises at least one optical amplifier, and wherein the first and second connecting modules are configured to couple such that the optical connection signal is transmitted and received across a light transmissive interface.

Abstract:
A method and system for controlling and monitoring street lights using optical link signaling through free space which does not require an FCC license for operation. The optical link signaling is accomplished in the space between street lights by using LEDs for both area lighting and optical signaling. A Street lighting system luminaire comprises a structural member such as a pole, a lamp comprising one or more LEDs, and an optical receiver that receives optical signaling from one or more other luminaires in street lighting network. The modulator modulates the output of the lamp to launch data into the street lighting system for transport. The optical receiver and modulator enables strobing and flashing modes such as required to support emergency services.
Abstract:
A communication system includes an omnidirectional antenna to receive a wideband primary signal, a nulling antenna to receive a secondary signal and a controller. The nulling antenna is oriented to place a null in a direction of a desired communication signal and the controller subtracts a processed secondary signal from a processed wideband primary signal to produce a jamming cancelled signal.
