  • Patent number: 11672070
    Abstract: A luminaire which provides illumination (in some cases, in a coordinated manner with other nodes of a lighting network) in an industrial environment is further configured to serve as a node of a wireless process control or industrial network, which may be a mesh and/or time-synchronized wireless network. Upon detecting a loss of mains power and/or other triggering condition, the luminaire node allocates an amount of available battery power to maintain the routing of process control messages, and allocates at least some of a remaining amount of available battery power (if any) for performing lighting activities such as driving illumination and/or lighting-related communications. The allocations for (e.g., the relative priorities of) support for process control and support for lighting activities may be based on an allocation configuration and/or based on instructions received from other components of the process control network and/or the lighting network, which may include user interface devices.

  • Patent number: 11658664
    Abstract: Asynchronous circuits implemented using threshold gate(s) and/or majority gate(s) (or minority gate(s)) are described. The new class of asynchronous circuits can operate at lower power supply levels (e.g., less than 1V on advanced technology nodes) because stack of devices between a supply node and ground are significantly reduced compared to traditional asynchronous circuits. The asynchronous circuits here result in area reduction (e.g., 3× reduction compared to traditional asynchronous circuits) and provide higher throughput/mm2 (e.g., 2× higher throughput compared to traditional asynchronous circuits). The threshold gate(s), majority/minority gate(s) can be implemented using capacitive input circuits. The capacitors can have linear dielectric or non-linear polar material as dielectric.

  • Patent number: 11658662
    Abstract: Methods, systems, and devices for leakage current reduction in electronic devices are described. Electronic devices may be susceptible to leakage currents when operating in a first mode, such as an inactive (e.g., a standby) mode. To mitigate leakage current, an electronic device may include transistors coupled in cascode configuration where a gate of a drain-side transistor in the cascode configuration is configured to be biased by an adjustable (e.g., a dynamic) control signal. When the transistors are inactive (e.g., “off”), the control signal may be adjusted to prevent leakage associated with the inactive transistors. Further, a source-side transistor in the cascode configuration may be configured to have a high threshold voltage (e.g., relative to the drain-side transistor).

  • Patent number: 11653428
    Abstract: The present invention relates to an intelligent power-saving LED light, which can maintain constant brightness and save energy by reducing the number of lighted LEDs of LED modules as outside temperature of a lighting device, such as a street light, having a plurality of LED modules gets lower.

    Abstract: A lighting arrangement such as a LED lamp comprises a light source and associated current driver, or a set of at least two parallel light sources and associated current drivers, supplied by a DC voltage from a voltage-regulated power converter. A feedback circuit provides a temperature-dependent control input to a control loop of the power converter, such that the DC voltage is adjusted in dependence on a sensed temperature. In this way, the voltage headroom required can be reduced, and efficiency gains are made.

  • Patent number: 11576238
    Abstract: This document describes systems and techniques that use a virtual temperature-sensor for active thermal-control of a lighting system having an array of LEDs. The system and techniques use a forward voltage across the array of LEDs as the virtual temperature-sensor, converting the forward voltage to a level that is detectable by an MCU of the lighting system. In response to determining that the forward voltage exceeds a threshold, the lighting system may reduce an amount of an electrical current provided to the array of LEDs to decrease the forward voltage and alleviate a thermal condition that may be detrimental to the array of LEDs, thereby maintaining luminance capabilities of the array of LEDs and prolonging life of the array of LEDs.
