  • Patent number: 10136493
    Abstract: A system monitors operational status of a lighting element. A lighting fixture processor instructs a lighting element to illuminate at a predetermined time, receives sensed light level information from the light sensing element, and transmits a message including information representing the sensed light level. A room controller can control some or all of these steps. A daylighting arrangement includes a room controller that instructs the lighting fixtures of a lighting group to illuminate their lighting elements at a predetermined time of day. Sensed light level information is obtained and transmitted to the room controller, which determines an initial daylighting target for the lighting fixture group based on an average of the sensed light level information. The room controller instructs the lighting fixtures to illuminate their respective lighting elements in accordance with the initial daylighting target.

  • Patent number: 10090841
    Abstract: A Josephson inverter gate circuit provides efficient implementation of polarity or logical inversion while eliminating the need for physically large high-efficiency magnetic transformers in the signal path. The circuit can consist of a half-twisted Josephson transmission line (JTL) or a JTL with an unshunted floating Josephson junction that produces two single flux quantum (SFQ) pulses when triggered by an SFQ input signal, which results in an output SFQ signal of reversed polarity. Implemented as a logical inverter, proper initialization of the circuit is accomplished within the signal inversion stage with flux biasing.
