Abstract: A capacitive touch sensing system for a capacitive touch panel uses analog circuitry to perform capacitive sensing and signal processing. The system operates over several time phases to charge and discharge a capacitive sensor of the touch panel and determine its capacitance. The system actively reconfigures and reuses circuit components over the several phases to minimize circuit size, complexity and power usage. The result is greatly reduced chip area by performing major signal processing functions in a small piece of analog circuitry. This reduces cost by combining the signal processing functions into a small, time-sequenced switched-capacitor analog circuit.

Abstract: The invention provides a receiver associated with a body, e.g., located inside or within close proximity to a body, configured to receive and decode a signal from an in vivo transmitter which located inside the body. Signal receivers of the invention provide for accurate signal decoding of a low-level signal, even in the presence of significant noise, using a small-scale chip, e.g., where the chip consumes very low power. Also provided are systems that include the receivers, as well as methods of using the same.

Abstract: There is provided a concurrent driving capacitive touch sensing device including a drive end, a capacitive sensing matrix and a detection end. The drive end simultaneously inputs encoded and modulated drive signals into a plurality of channels of the capacitive sensing matrix within each drive time slot of a frame. The detection end detects a detection matrix of the channels in the frame and decodes the detection matrix so as to generate a two-dimensional detection vector corresponding to each of the channels.

Abstract: A demodulator for frequency shift keyed carrier signals is described. A conditioned F.S.K. signal is simultaneously fed to a pair of rising edge triggered single shot voltage generators, such carrier signal being inverted prior to being fed to one of such single shots. The single shots are each triggered upon receipt of a cycle edge to initiate an output pulse having a duration falling between the time intervals distinctive of the cycles of the two possible carrier signal frequencies. The next rising edge received by each causes the respective single shots to retrigger, and latches the previous output of each into the first element of an associated serial memory device. The successive elements of each of the serial memory devices, store the state output signals of adjacent cycles of the carrier signal, with the states in one of such devices being one-half cycle apart from the states in the other.

Abstract: In an electronic communication system, having a central transmitting station and N remote receiving stations, the central station sends out a signal train consisting of a wide reset or synchronizing pulse (R) and a series of N narrower time-sequenced or time-slotted clock pulses (C). An intermediate width station selector pulse (S) in the signal train designates a call to a particular remote station. The receiving stations are equipped to recognize, acknowledge and respond to the signal train in the correct fashion if in the calling mode or in the polling mode of operation.
