Abstract: A touch detection circuitry includes an analog-to-digital converter (ADC), a controller, and a packet generator. The ADC is arranged to convert touch signals of a touch panel from analog form into digital form. The controller is electrically connected to the ADC, and is configured to calculate at least one coordinate point and at least one touch size respectively corresponding to at least one touch event on the touch panel based on the touch signals. The packet generator is electrically connected to the controller, and is configured to encapsulate the at least one coordinate point and the at least one touch size into a touch data packet.

Abstract: A micro secure digital (SD) adapter, for adapting a micro SD card to an SD interface, the micro SD adapter comprising a micro SD slot, for disposing the micro SD card; a pin module, comprising a plurality of signal pins, a first ground pin, and a second ground pin; a plurality of connectors, for conducting the plurality of signal pins and the first ground pin to the micro SD card according to a pin configuration of the micro SD card when the micro SD card is disposed in the micro SD slot; and a conducting module, electrically connected between a terminal of a first connector corresponding to the first ground pin and the second ground pin.

Abstract: A memory device includes a control board and a conductive housing. In one embodiment, a circuit ground in the control board is electrically coupled to the conductive housing to make a common ground contact. In another embodiment, differential impedances at different locations of a conductor are controllably maintained within a specified range by adjusting width of the conductor and/or spacing between the adjacent conductors of a differential pair.
