Abstract: This invention relates a laser vibrometer. A frequency modulated laser source (2, 3) generates a frequency modulated output, preferably a linear ramp, which is used for both the transmit beam and the local oscillator signal. Transmit (26) and receive optics (27) transmit the transmit beam towards a target and receive radiation returned therefrom. The local oscillator is mixed with the received beam and the mixed signal detected by a detector array (28). Before mixing with the received radiation however the local oscillator is delayed for a time substantially the same as the flight time of the radiation, preferably through a variable optical delay (32). Delaying the local oscillator signal in this way means that the received radiation was generated at nearly the same time as the local oscillator signal with which it was mixed and both received the same modulation.

Abstract: Systems and methods for communicating data from field devices to data acquisition systems. In at least some exemplary embodiments, a remote process or field controller may obtain data, and send the data to a data cache only if the data has changed from previously sent data. The data acquisition system may poll the data cache for data. Having the remote process controller send only data that has changed allows the communication channel between the data caching system and the remote process controller to have a bandwidth or throughput lower than what may be needed to support the polling of the data acquisition system.

Abstract: Determining a hierarchical structure, possibly for delivery to an asset management system. Some exemplary embodiments may be a method comprising receiving a message originated by a data acquisition system and destined for a remote process controller (the receiving by a message router), using content of the message to determine a hierarchical structure of a system between the data acquisition system and the remote process controller, forwarding the message by the message router, and passing information related to the hierarchical structure to an asset management system.

Abstract: A coherent laser radar (lidar) device is described. The device has a transmitter portion that comprises a single wavelength laser source, a conversion means (such as an electro-optic modulator) for producing a combined light beam that comprises at least two component light beams of discrete wavelength from the output of said single wavelength laser source, and transmit optics to direct the combined light beam to a remote target. Each component light beam of the combined light beam traverses the same optical path from the single wavelength laser source to the transmit optics. The device is used to make differential absorption measurements.

Abstract: A coherent differential absorption lidar (DIAL) device 2 comprises a transmit portion 4 for directing a combined light beam to a remote target and a receive portion 5 for receiving light returned from the remote target and for coherently mixing the received light with its associated local oscillator beam. The combined beam comprises at least two component light beams of discrete wavelengths. The device further comprises a signal correction means. The signal correction means comprising a means for extracting a portion of each component light beam from the transmit portion, a means for introducing a frequency difference 62 between each extracted component light beam and its associated local oscillator beam and a means for directing the extracted beam into the receive portion. This provides an additional correction signal thereby improving device performance.

Abstract: A lighting assembly 2 includes a ballast subassembly 4, fluorescent lamps 30 and connectors 50 for connecting the ends of two lamps forming an associated pair. The ballast subassembly 4 is connected to only one base of two lamps and the other ends are connected by commoning socket connectors 50 that are not attached to the ballast subassembly 4. The ballast subassembly 4 includes a power supply circuit 100 and a ballast circuit 102 that can energize two fluorescent lamps 30 with remote lamp bases 34 commoned. The ballast subassembly 4 is mounted on one end of the lighting subassembly, for example on one end of a troffer 80. No wires or other direct electrical connection are necessary with the other end of the lighting assembly 4, the lamps 30, or the troffer 80. The commoning connectors 50 can employ bus contacts 64 having integral cantilever terminals 74 extending from a central bus section 66.

Abstract: A stacked electrical connector 2 including right angle RJ-45 modular jacks 4 positioned in columns also includes LED's 38 positioned on the front mating face 18 of the connector 2. Internal passages 28 extend from the mating face 18 of the jack housing 18 and intersect channels 34 extending to the bottom pcb mounting face 22 where the connector 2 and jacks 4 are soldered to a printed circuit board. LED leads 42 are located in the passages 28 and contacts 44 are located in channels 34. Insulation displacement slots 48 at the top of the contacts 44 terminate the leads 42. The termination points are staggered and the leads 42 in a column are of different lengths so that contacts 44 of different lengths can engage corresponding leads 42. LED's 38 can thus be positioned beside mating openings 20 on the front of the connector 2 to provide status indications.

Abstract: A communications wiring system includes a communications network interface device for routing a plurality of source signals between respective ones of a plurality of types of electrical sources and a number of reconfigurable outlet assemblies. Each reconfigurable outlet assembly selectively establishes electrical connection with predetermined ones of the electrical sources, via a cable. The communications network interface device receives and splits the source signals into a predetermined number of subsignals which are routed to respective reconfigurable outlet assemblies. Each reconfigurable outlet assembly includes an outlet and a number of interchangeable electrical connectors, such as modular jacks, adapted to be removably mounted to the outlet for establishing electrical connection with a predetermined electrical source. In order to establish electrical connection with a different electrical source, a first electrical connector can be removed and a second electrical connector can be inserted therein.
