Abstract: A contactless encoder is disclosed. The encoder comprises a selector configured to select one of a plurality of states associated with the encoder. The encoder furthermore comprises an integrated circuit comprising a finite state machine configured to detect a currently selected state by the selector and generate an output signal corresponding to the detected currently selected state, wherein the currently selected state is detected based on a capacitive coupling between the selector and a portion of the encoder associated with the currently selected state.

Abstract: A capacitive coupling based sensor is disclosed. In some embodiments, a sensor comprises a transmitter and a receiver that are configured to be capacitively coupled when a coupling condition is satisfied as well as a circuit configured to determine whether a received signal that is received by the receiver matches a transmitted signal that is transmitted by the transmitter.

Abstract: Stored data elements are read from a first-in-first-out (FIFO) buffer memory in a pipelined fashion. A look-ahead fetching technique is utilized during a memory read cycle operation to advance (select) a subsequent data element in preparation for a next read command. Data read in advance is not output, however, until a subsequent read cycle corresponding to a next request for data in the buffer memory. A first data element written into the buffer memory is stored in an initial data register. Upon a first read request, the first data element is output from the initial data register. A first and a second memory array are provided for alternately storing successive ones of data elements written into the buffer memory. While a presently requested data element from the first array is being output, a memory cell in the second array, which contains the next data element to be requested, is selected and sensed, and the sensed value placed on an output line.
