Abstract:
1. A method for providing communications between (1) a capacitor sensor touch screen device that includes a capacitor sensor touch screen that includes capacitor sensors and provides a display function and (2) a capacitor sensor device that includes one or more capacitor sensors that detect or sense, based on capacitive sensing and without providing a display function, signals transmitted from the capacitor sensor touch screen of the capacitor sensor touch screen device, comprising: placing the capacitor sensor device without a display function in proximity of, or in contact with, a body part of a user to be in capacitive coupling with the body part; operating the capacitor sensor touch screen device to (1) control the capacitor sensor touch screen to provide touch-based user interfacing between the user and the capacitor sensor touch screen device, and (2) operate the same capacitor sensor touch screen to sense a device-to-device communication signal from the capacitor sensor device without a display function to allow device-to-device signaling between the capacitor sensor touch screen device and the capacitor sensor device without a display function via capacitive coupling through the human body of the user; operating the capacitor sensor touch screen device to initiate a device-to-device connection initiation signal and to multiplex the device-to-device connection initiation signal in time with a touch screen signal that provides touch-based user interfacing between touching of the capacitor sensor touch screen by the user and the capacitor sensor touch screen device so as to direct the multiplexed signal to the capacitor sensor touch screen; operating the capacitor sensor touch screen to receive an acknowledgement to the device-to-device connection initiation signal in a device-to-device communication signal from the capacitor sensor device without a display function; when the acknowledgment is detected, operating the capacitor sensor touch screen device to send the capacitor sensor device without a display function an acknowledgment back signal that is multiplexed in time with a touch screen signal to the capacitor sensor touch screen; and subsequently operating the capacitor sensor touch screen device to use one or more time slots in a touch screen signal that are not used for touch-based user interfacing between touching of the capacitor sensor touch screen by the user and the capacitor sensor touch screen device to communicate with the capacitor sensor device without a display function.
