  • Patent number: 10690699
    Abstract: A holder for a current sensor having separable portions with inner surfaces forming an opening and opposing outer surfaces having a groove to accommodate a current sensing coil. The holder includes flexible members on the portions and extending toward the opening such that the flexible members can hold a power cable substantially centered within the opening and concentric with the current sensing coil. The portions are joined together with a hinge pivotally mounted between them at one end and a releasable clasp joining them together at another end, providing for ease of installation around the power cable by hand and without requiring tools or additional fasteners.

  • Publication number: 20190349727
    Abstract: A wireless sensor communication system for an enclosure includes a communication gateway and communication nodes within the enclosure. Each communication node includes a processor, a sensor, and a communication module. Each of the communication nodes is configured to wirelessly transmit information within the enclosure to another one of the communication nodes, and at least one of the communication nodes has an obstruction with the communication gateway impeding direct wireless communication with it. The communication nodes are configured to aggregate information received from obstructed communication nodes and wirelessly transmit the aggregated information. The aggregation of information for transmission provides for hopping communication to send sensor data or other information from the obstructed communication nodes to the communication gateway via other communication nodes.

  • Publication number: 20160225248
    Abstract: An underground data communication apparatus, system, and method are described. The data communication system includes a transceiver disposed on an entrance port to an underground vault or enclosure, where the transceiver includes a rugged housing, where at least a portion of the rugged housing extends above the surface of the entrance port. A monitoring device is disposed in the vault. The monitoring device can be a sensor that provides data related to a real-time condition within the vault. In addition, the data communication system includes a gateway unit that relays the data to the transceiver. The gateway/transceiver can take a combination of wireless and/or wired signals from the monitoring device which provides real-time data regarding environmental, component, and/or other electronic equipment conditions for those components/equipment disposed within the vault.

  • Patent number: 8072687
    Abstract: A front projection display device includes an optical engine including an illumination system, an imaging system, and projection optics. The projection optics include a first lens group of negative refractive power that has at least one aspheric surface. The projection optics output an image at a half field angle of at least 45°, where the image has substantially no distortion. For example, when the first lens group is placed at a distance of less than 1 meter from a viewing screen, the output image has a size of about 40 inches diagonal or greater, and requires substantially no keystone correction. In other aspects, the optical engine can be implemented in a wall-mounted projection system, a multimedia system, a compact integrated monitor system, and a portable projection unit.
