Abstract: Techniques and mechanisms for determining a delivery of power by a programmable power supply. In an embodiment, controller circuitry of a platform receives an indication that a load of the platform is to transition to a particular operational mode. Based on a power requirement of the operational mode, the controller circuitry identifies a mode of voltage regulation which is to be provided with converter circuitry of the platform. The controller circuitry signals that a programmable power supply, which is coupled to the platform, is to output a supply voltage at a level which is based on an amount of power loss associated with the mode of voltage regulation. In another embodiment, the controller circuitry identifies the mode of voltage regulation based on an amount of charge which is currently stored by a battery of the platform.

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: A first apparatus is disclosed, including: a detection circuitry to detect a first voltage level of reference current received from a second apparatus, where the second apparatus is to provide the reference current at a second voltage level; and a controller to negotiate a power transmission agreement with the second apparatus for transmission of power from the second apparatus to the first apparatus, based at least in part on a difference between the first voltage level and the second voltage level.

Abstract: Techniques for battery retention are disclosed. In the illustrative embodiment, a thin polyurethane strap is used to hold a battery in place. The strap only requires a small amount of volume, allowing for a higher volume (and higher capacity) for the battery. In order to accommodate swelling, a computing device that has a battery held in place with such a strap can have an open area above the battery. The strap may have ridges to contact the battery and the component above the battery beyond the open area. If the battery swells, the ridges may be pressed down, accommodating the swelling battery.

Abstract: An apparatus is provided which includes: an input/output (I/O) port to be coupled to a device external to the apparatus; a battery having an output node; a voltage regulator to selectively supply power from the I/O port to the battery, to charge the battery; and a switch coupled between the I/O port and the output node, wherein the switch is to selectively allow flow of current from the device to the output node by bypassing the voltage regulator.

Abstract: Methods and apparatus to detect user-facing screens of multi-screen devices are disclosed. An example computing device includes a touch point analyzer to detect a number of touch points on at least one of a first touchscreen and a second touchscreen of a multi-screen device in response to a trigger event. The example computing device includes a screen selector to designate one of the first and second touchscreens as an active screen and the other of the first and second touchscreens as an unused screen based on the number of touch points.

Abstract: Embodiments are directed to notifying a user of a computing device in response to detectable events. A context assessment generates context indicia relating to usage of the computing device based on sensor data and content data of the computing device. An event descriptor assessment produces a master set of event descriptors based on the context indicia and on event descriptor selection criteria, with the event descriptors representing events monitorable by the computing device. An event descriptor relevance assessment is made to produce a smaller active subset of event descriptors containing events to be monitored by the computing device such that in response to detection of any of the events to be monitored a user notification is triggered.

Abstract: A method and apparatus converts a force applied to a touch screen of an electronic device into an electric charge capable of powering a logical circuit of the electronic device. In various embodiments, the touch screen comprises one or more piezoelectric transducer array layers that convert the force into electrical charges. The converted electrical charges may be collected in a capacitor array layer, which can be discharged in order to power logical circuits of the electronic device or to charge a battery of the electronic device.
