  • Patent number: 8757560
    Abstract: A cable retention device is disclosed. The device may be used to restrain electrical cables routed along a cable support structure. These support structures are used in both internal and external settings, and the structures provide some physical support and protection to the electrical cables. In some high-power settings, these cables run from substations or electrical generators to a point within a facility. The support structures typically used in these settings do not fully restrain the cables. External forces, such as those that may occur during short circuit conditions, may result in movement of the electrical cables, which can lead to damage. Cable retention devices, referred to at times as cleats or clamps, are needed to restrain the cables. The cable retention device disclosed herein simultaneously restrains the cables and secures the cables to the cable support structure.

  • Publication number: 20070091623
    Abstract: A plurality of networked luminaire managers, each collocated with a respective luminaire, monitor the status of their respective luminaires. The luminaire managers include transmitters for transmitting status information about their respective luminaires and third-party devices to a network server. The network server forwards the received status information from the networked luminaire managers to a computer of an owner/operator of the plurality of luminaires and/or a third-party user. The luminaire managers communicate with each other, whereby they form a network.

  • Publication number: 20070085702
    Abstract: A light management system having networked intelligent luminaire managers. A plurality of networked luminaire managers, each collocated with a respective luminaire, monitor the status of their respective luminaires. The luminaire managers include transmitters for transmitting status information about their respective luminaires such as, for example, a lamp out condition upon occurrence of such a lamp out condition, to a network server. The network server forwards the received status information from the networked luminaire managers to a computer of an owner/operator of the plurality of luminaires. The luminaire managers communicate with each other, whereby they form a network.

  • Patent number: 6533366
    Abstract: Hydraulic or electro-hydraulic braking systems which include at least one wheel braking device and micro-machined technology, such as microvalves, are described herein. The use of the microvalves helps to eliminate audible noise produced in the hydraulic systems as well as allows for reduced package size of the system. In particular, many of the braking systems described herein have Anti-lock Braking System (ABS) capabilities, and as such employ apply microvalves, dump microvalves and changeover microvalves. The microvalves may be digitally or proportionally controlled for selectively controlling the pressure supplied to the wheel brake cylinders.

  • Patent number: 6312061
    Abstract: A plurality of pressure sensors are carried in housing mounted upon a hydraulic control valve for an electro-hydraulic brake system. The pressure sensors are electrically connected to a signal conditioning circuit which also is mounted upon the hydraulic control valve. The signal conditioning circuit samples the sensors and mulitplexes the sensor signals into a single output signal.
