  • Patent number: 11867386
    Abstract: This document describes techniques directed to active thermal-control of a floodlight and associated floodlights. As described, an example floodlight includes a first heat-transfer subsystem that uses a fully enclosed heat sink to transfer heat from an array of LEDs to a first housing component of the floodlight. The floodlight further includes a second heat-transfer subsystem to transfer heat from one or more PSUs to a second housing component of the floodlight. Described techniques include using thermistors located throughout the floodlight to actively monitor a temperature profile within the floodlight and, if one or more operating-temperature thresholds are violated, reducing power consumption within the floodlight.

  • Patent number: 11832426
    Abstract: The present disclosure describes thermal mitigation for an electronic speaker device and associated systems and methods. The thermal mitigation includes monitoring several thermal zones to determine or estimate thermal conditions in corresponding parts of the electronic speaker device. The thermal zones may include a System-on-Chip (SoC) integrated circuit (IC) component, audio components including power-dissipating IC components, and a temperature of an exterior surface of a housing component of the electronic speaker device. To mitigate thermal runaway, different throttling schemes may be triggered based on the thermal zones exceeding certain thermal limits. The throttling schemes may include reducing the amount of power supplied to the SoC, reducing audio power of the audio components to a lower wattage, or manipulating SoC cores such as by disabling one or more of the cores or adjusting utilization of the SoC cores.

  • Patent number: 11812583
    Abstract: This document describes a passive thermal-control system that is integrated into a mesh network device. The passive thermal-control system, which may include a heat sink and multiple heat spreaders, is such that heat originating with integrated circuit devices of the mesh network device and a speaker module of the mesh network device may be transferred to other components of the mesh network device, such as a housing component of the mesh network device. The heat may then be dissipated to an external environment to maintain a desired thermal profile of the mesh network device.

  • 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.

  • Patent number: 11563893
    Abstract: A camera system includes a lens assembly and image processing electronics internal to the camera housing and thermally coupled to the battery assembly. The battery assembly is sensitive to low ambient temperatures and may become damaged if the temperature of the assembly becomes sufficiently low. The camera system comprises a thermal management system that dissipates heat from electronic components of the camera to increase or maintain the temperature of the battery assembly. The thermal management configures the electronic components in different modes to create a step-wise increase of the resistive heat generated in the camera system and thereby increase the temperature of the components in the camera system.
