Abstract: Devices for mitigating or stopping noise or surface current on a display are provided. An electronic device including a display may include a display substrate, a mid-support plate that is adjacent to the display substrate, and a lower support plate that is adjacent to the mid-support plate. A space exists between the mid-support plate and the lower support plate. The mid-support plate includes one or more electromagnetic band gap (EBG) structures formed through the mid-support plate, one or more electromagnetic band gap structures mounted onto the mid-support plate, or both. The one or more electromagnetic band gap structures may mitigate or stop surface current flow across the display.

Abstract: An electrically activated lens filter with an electro-optic portion having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter include an electro-optic portion having one or more conductive plugs arranged around a center region such that an electric field within the electro-optic portion varies from a maximum at an outer rim to a minimum outside of the center region. The lens filter may include a plurality of front electrodes and rear electrodes accessible in an axial direction for electrically activating front and rear transparent conductive layers, respectively.

Abstract: A method and apparatus for memory calibration averaging is disclosed. In one embodiment, a memory subsystem includes a memory and a memory controller. The memory controller includes a calibration control circuit that periodically performs calibrations of the memory subsystem. Calibration may be performed for a delay applied to a data strobe used to synchronized transfers of data between the memory controller and the memory, and a reference voltage used to distinguish between a logic 0 and a logic 1 during memory reads. Following the performance of a calibration, the values of the delay and the reference voltage may be set based on an average of a most recent number of calibrations.
