Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed that implement an off-screen indication of battery charge in mobile platforms. In an example, the apparatus includes a keyboard, an interface circuitry, and a processor circuitry. The example processor circuitry to instantiate remaining state of charge (RSOC) controller circuitry to detect a battery charge level display event on a mobile device, the mobile device in a pre-boot state. The example processor circuitry additionally to instantiate fuel gauge circuitry to determine a charge level of a battery of the mobile device and keyboard display circuitry to, after the battery charge level display event, cause a display of the charge level of the battery in the pre-boot state with ones of backlights of a second ones keys on the keyboard.

Abstract: A buck-boost converter having dual-folded bootstrap for driver metal oxide semiconductor (DrMOS) device that, in addition to the traditional bootstrap capacitors, include folded bootstrap capacitors that cross-couple inductor nodes to the two sets of DrMOS switches. The DrMOS switches can be n-type or p-type, and can be replaced with driver Gallium Nitride (DrGaN) devices.

Abstract: Techniques and mechanisms for improving an efficiency of power delivery resources. In one embodiment, switch circuitry is operated based on an indication from an integrated circuit (IC) die that circuitry of the IC die is ready to accommodate a low power state which disables a delivery of power to the IC die by a voltage regulator (VR). The switch circuitry is operated, based on a control signal is also used to disable said power delivery, to disable or otherwise prevent one or more conductive paths which are each between a respective two of a battery pack, a voltage regulator, or a battery charger. In another embodiment, the low power state enable a rail for circuitry which is to provide a real time clock signal to the IC die, but disables any other rails which power the IC die.

Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system having a heat exchanger configured to thermally regulate a supply air flow, where the heat exchanger includes a thermoelectric device, a first plurality of fins coupled to the thermoelectric device, and a second plurality of fins coupled to the thermoelectric device. The first plurality of fins extend into a supply air flow path of the supply air flow to transfer thermal energy between the thermoelectric device and the supply air flow and the second plurality of fins convectively transfer thermal energy between the thermoelectric device and a working fluid exterior the supply air flow path.

Abstract: A method for detection of a fault in a sensing cable within a saw detects potential failures in a sensing cable that is part of an object detection system in the saw. The method includes generating a predetermined excitation signal transmitted through a first conductor and a second conductor in the sensing cable, detecting a return signal from the first conductor and the second conductor in the sensing cable in response to the predetermined excitation signal, identifying a signal-to-noise ratio (SNR) of the return signal, and generating an output indicating a fault in the sensing cable in response to the SNR of the return signal being below a predetermined value.
