Abstract: Methods for automatic calibration of a braille interface. In embodiments, a user begins typing braille characters in 2×3 matrix into an interface without an initial calibration step. The implementing system detects the patterns of the keystrokes and determines the orientation and placement of the user's hands by comparing the keystrokes against known braille characters, identifying which row and column of the 2×3 matrix within which each finger is positioned. The interface is then calibrated based on the identified positions of the fingers within the 2×3 matrix. For touch interfaces, the surface area of each finger may also be used to enhance identification of fingers. Other embodiments may be described and/or claimed.

Abstract: A computing system having a high-performance battery pack (e.g., 3S, 4S battery packs) coupled to a voltage regulator and logic to control an input supply of the voltage regulator. The logic determines the context of usage of the computing device (or user attentiveness) and either dynamically bypasses the voltage regulator to provide the voltage from the high-performance battery pack directly to various components of the computing system, or dynamically engages devices of the voltage regulator to provide a lower supply voltage to the various components of the computing system.

Abstract: Described are mechanisms and methods to facilitate power saving in Type-C connectors. Some embodiments may comprise an interface to a Configuration Channel (CC) signal path and to a ground signal path of a Universal Serial Bus (USB) Type-C connector port, a first circuitry, and a second circuitry. The first circuitry may be operable to place toggled values on the CC signal path. The second circuitry may be operable to couple the ground signal path to a detection signal path. The placement of the toggled values on the CC signal path is enabled when the detection signal path carries a first value that corresponds with the USB Type-C connector port being connected to a USB Type-C device, and may be disabled when the detection signal path carries a second value that corresponds with the USB Type-C connector port not being connected to a USB Type-C device.

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 processor includes a transmitter to transmit, to a receiver, a differential pair of signals including a positive signal transmitted across a positive conductor and a negative signal transmitted across a negative conductor. A first programmable analog delay circuit is coupled to the positive conductor to provide a first delay to the positive signal and a second programmable analog delay circuit is coupled to the negative conductor to provide a second delay to the negative signal. A controller receives data based on a bit error rate (BER) of the differential pair of signals as measured by a bit error checker of the receiver. In response to determining the BER is less than a threshold BER, the controller stores a first delay value to program the first delay and store a second delay value to program the second delay.
