    Abstract: Methods and apparatus for duty cycle adjuster optimization training algorithms to minimize jitter associated with DDR5 DRAM transmitters. Basic and Advanced Duty Cycle Adjuster (DCA) training algorithms are implemented to reduce duty cycle error and hence reduce phase mismatch translated jitter in the transmitter DQS signals. In accordance with aspects of the Basic DCA training algorithm, duty cycles for QCLK, IBQCLK, and QBCLK are adjusted by a memory controller that utilizes a DCA function implemented on a memory module (e.g., DDR5 SDRAM DIMM) to obtain a first set of optimized DCA code settings. The first set of optimized DCA code settings are then used as initial settings for the Advance DCA training algorithm to further optimize the DCA code settings for QCLK, IBQCLK, and QBCLK. A similar technical may be employed to reduce duty cycle error and jitter for DQ signals.

    Abstract: Systems, apparatuses and methods may provide for detecting an identifier communication from a writing implement and transitioning a previously modified interior page of an electronic notepad from a locked state to an unlocked state if the identifier communication corresponds to one or more stored identifiers. Moreover, a plurality of additional interior pages of the electronic notepad may be maintained in the locked state while the previously modified interior page is in the unlocked state.

    Abstract: Technologies for interfacing an input overlay device with a touch screen of a computing device are disclosed. A computing device includes a touch screen and at least one processor to execute instructions to: determine parameters associated with an input overlay device overlying the touch screen, the input overlay device separate from the computing device, the parameters to identify a first area of the touch screen and a second area of the touch screen different than the first area, the first area corresponding to an area of the touch screen covered by the input overlay device; detect a position of a touch on the touch screen; if the position of the touch is in the first area, determine an input for the computing device based on the position of the touch; and if the position of the touch is in the second area, ignore the touch.

    Abstract: Embodiments of the present disclosure provide for an apparatus for facilitating a connection with an external sensor module, in accordance with some embodiments. In one instance, the apparatus may include a processor and a sensor hub coupled with the processor, wherein the sensor hub may include a bus to provide a connection between the apparatus and the external sensor module. The apparatus may further include signal pattern generation circuitry coupled with the sensor hub to generate a signal pattern in response to a connection of the external sensor module to the apparatus via the bus or disconnect of the external sensor module from the bus, to indicate an insert or remove event to the apparatus, and facilitate the connection of the apparatus with the external sensor module. Other embodiments may be described and/or claimed.

    Abstract: Technologies for interfacing an input overlay device with a touch screen display of a compute device are disclosed. A compute device may detect that an input overlay device has been placed on top of its touch screen display. After detecting the input overlay device, the computing device determines one or more parameters for the input overlay device. The computing device may then detect an additional touch on the portion of the touch screen display currently covered by the input overlay device. The compute device can then determine an input of a user based on the position of the touch and the one or more parameters of the input overlay device.
