    Abstract: A battery pack includes a battery, a first temperature sensor configured to provide a first temperature value associated with a temperature of the battery, a heat source disposed proximate to the battery and configured to heat the battery, a second temperature sensor configured to provide a second temperature value associated with a temperature of the heat source, and a control board coupled to the first temperature sensor and the second temperature sensor, wherein the control board is configured to receive the first temperature value and the second temperature value. The control board is configured to compare the first temperature value and the second temperature value to determine a temperature gradient between the battery and the heat source and transmit an alert if the temperature gradient exceeds a first temperature gradient threshold.

    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.

    Abstract: This document describes a thermal-control system that is integrated into a media-streaming device. The thermal-control system includes a combination of heat spreaders and materials with high thermal-conductivity. The thermal-control system may spread, transfer, and dissipate energy from a thermal-loading condition effectuated upon the media-streaming device to concurrently maintain temperatures of multiple thermal zones on or within the media-streaming device at or below multiple respective prescribed temperature thresholds.

    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.

    Abstract: The present document describes a passive thermal-control structure for speakers and associated apparatuses and methods. The architecture of the passive thermal-control structure is such that heat is transferred from electronic subsystems of the electronic speaker device to the passive thermal-control structure, which acts as an internal, structural frame of the electronic speaker device and provides both thermal mitigation and structural stability. The passive thermal-control structure conducts heat from the electronic subsystems to a housing of the electronic speaker device. The housing of the electronic speaker device may dissipate the heat to the ambient environment to prevent thermal runaway of the electronic subsystems, and the internal frame mitigates the temperature of the housing from exceeding ergonomic temperature limits.
