  • Patent number: 11942720
    Abstract: A dry mate cable connection includes a data cable. The data cable includes a plurality of electrical conductors and at least one electrically insulating outer layer surrounding each data conductor, whereby the data conductors are electrically insulated from one another. The cable includes a termination end. The outer layer of each conductor is physically in contact with an outer layer of an adjacent conductor, except at the termination end. The plurality of electrical conductors at the termination end are physically separated from one another by a single electrically insulating overmoulded cable termination housing. The housing is in contact with at least part of the electrically insulating layers of each of the electrical conductors.

  • Patent number: 11781774
    Abstract: The air flow of an HVAC system for a multi-story building B is controlled by optimizing the pressure setpoint at the return air plenum PL-1 used for removing or recirculate air from the building, by measuring a pressure differential between the building B air and atmosphere A air at a sensor location P-2, computing a desired pressure differential between the building B air and atmosphere A air, based upon a computed stack effect pressure that is expected to develop at the sensor location on the building for the current inside and outside air temperature in the absence of mechanical action, and controlling the return air fan and damper D-1 to pressurize the air in at the sensor location to produce the desired pressure differential between the building B air and atmosphere A air at the sensor P-2 location. Air pressure is also controlled between specific rooms and adjacent rooms by control of the conditioned air or return air paths connected thereto.

  • Patent number: 10891579
    Abstract: Provided are methods and apparatus that determine a benchmark of energy consumption for an energy system and utilize the determined benchmark in a variety of ways. Once determined, the determined benchmark may be compared to current energy consumption and current outdoor temperature to verify proper operation of the system and identify deviations in system operation. The benchmark may be used to determine the impact of an implemented change in the operation of the system. The determined benchmark may also be used to contract for a term in an agreement and to verify the satisfaction of a term in an agreement.

  • Patent number: 8810983
    Abstract: A system for protecting a load from a fault on a line comprising: a detection circuit monitoring the line; and a switch interposed between the line and the load; wherein the detection circuit triggers the switch to disconnect the load from the line when the fault is detected. The detection circuit may trigger the switch within one second of detecting the fault. The detection circuit may monitor the line voltage of the line and the fault may be detected when the line voltage exceeds 125% or 130% of the normal voltage. The load may be automatically reconnected to the line when the line voltage drops to within 5% or 10% of a normal voltage. The fault may be any one or more of an open-neutral, an over-voltage, an under-voltage, a phase loss, and an external trigger, such as an access sensor, a smoke sensor, and/or a heat sensor.

  • Patent number: 8300377
    Abstract: A transient voltage surge suppressor assembly comprising: a first energy absorbing device; a second energy absorbing device in parallel with the first device; and a voltage sense circuit configured to take the first device off-line when a voltage swell lasts for a duration. The first and second devices may be wired in parallel between a line and a neutral. The assembly may include a third energy absorbing device wired between the line and a ground, the third device also being configured to be taken off-line when the voltage swell lasts for the duration. The voltage sense circuit may be powered by a line voltage or a lower supply voltage. The first device may be more sensitive than the second device. For example, the first device may have a lower clamping voltage than the second device. The first device may be smaller and/or include fewer components than the second device.
