  • Lock-free first in, first out memory queue architecture
    Patent number: 10089038
    Abstract: First in, first out (FIFO) memory queue architecture enabling a plurality of writers and a single reader to use the queue without mutual exclusive locking. The FIFO queue is implemented using an array. A write counter value associated with the array provides a reservation value to each writer that is mutually exclusive of the value provided to every other writer. A read counter value associated with the array prevents writers from writing over data messages stored in the array that are yet to be read by the single reader.

  • Upstream parallel arc fault outlet protection method
    Patent number: 10084304
    Abstract: An arc fault circuit interrupter (AFCI) outlet is disclosed which detects and interrupts upstream parallel arc faults. The example AFCI outlet includes a switching element coupled between the line and neutral conductors at the outlet. The outlet also includes a voltage sensor and a current sensor. A parallel upstream arc fault is detected from a sensed voltage drop and no corresponding increase in current. On detecting the arc fault, the switching element is closed and current flows through the relatively lower resistance switching element interrupting power through the arc fault. The closed switching element results in an overcurrent condition causing an upstream conventional thermal-magnetic circuit breaker to trip.

  • Water resistant arc resistant outdoor switchgear air vent
    Patent number: 10079480
    Abstract: An arc resistant air vent for a switch gear cabinet comprises a plenum stacked with spaced corrugated plates, the plates being perforated by slots at the corrugation turning points. Air and water can enter through a front grille of the vent. Air is allowed to pass through to the cabinet while water entering the vent is returned through the perforations to a bottom wall of the plenum which drains at the grille. The plates are held in frangible connections to the side walls of the plenum and the slots produce an accordion hinge to allow a release and a folding of the plates together under the pressure of an arc blast in the switchgear cabinet to seal the grille.

  • THERMOSTATIC ACTUATOR FOR RADIATOR VALVE AND ZONED HEATING SYSTEM COMPRISING SAME
    Publication number: 20180259198
    Abstract: A thermostatic actuator for a radiator valve includes a thermostat mechanism configured to passively open the valve when an environmental temperature is less than a set point and to close the valve when the temperature is greater than the set point. A set point adjustment mechanism draws power from a power supply to selectively drive unitary movement of the thermostat mechanism to adjust the set point. Multiple actuators are used in a zoned radiant heating system in which a controller is operatively connected to the set point adjustment mechanism of each actuator to selectively transmit a control signal to actuate the set point adjustment mechanism to drive unitary movement of the respective thermostat mechanism to adjust the respective set point.
