    Abstract: A signal processing circuit with a pressure-sensitive sensor array includes a pressure-sensitive sensor array with M rows and N columns, and an excitation source adapted for outputting positive and negative excitation voltages, wherein: the positive output terminals of the sensing units at a same row of the pressure-sensitive sensor array are connected with each other and act as an output of the row; the negative output terminals of the sensing units at a same column of the pressure-sensitive sensor array are connected with each other and act as an output of the column; so that the whole pressure-sensitive sensor array has a positive excitation input end, a negative excitation input end, M row output signals and N column output signals. The signal processing circuit and method are capable of significantly decreasing an amount of output signal wires of the sensor, reducing connection areas, and improving reliability.

    Abstract: A robot includes a body and a bumper. The body is movable relative to a surface and includes a first portion of a sensor. The bumper is mounted on the body and movable relative to the body and includes a backing and a second portion of the sensor. The backing is movable relative to the body in response to a force applied to the bumper. The second portion of the sensor is attached to the backing and movable with the backing relative to the first portion of the sensor in response to a force applied to the bumper. The sensor is configured to output an electrical signal in response to a movement of the backing. The electrical signal is proportional to an amount of displacement of the second portion relative to the first portion.

    Abstract: A transducer structure including a carrier with an opening and a suspended structure mounted on the carrier which extends at least partially over the opening in the carrier is disclosed. The transducer structure may further include configuring the suspended structure to provide an electrostatic field between the suspended structure and the carrier by changing a distance between the suspended structure and the carrier. Alternatively, the suspended structure may be configured to change the distance between the suspended structure and the carrier in response to an electrostatic force provided between the suspended structure and the carrier.

    Abstract: A thermionic sensor is disclosed. The sensor includes a sensor housing at least partially defining an emission chamber in which at least a partial vacuum is maintained; a cathode disposed in the emission chamber; an anode disposed in the emission chamber and spaced apart from the cathode; and an electrically conductive layer disposed in the emission chamber facing the anode and cathode. The thermionic sensor is configured to output a detection signal when the anode and cathode are at substantially the same temperature.

    Abstract: The present invention is directed to an RFID device. The RFID device includes a brace affixed to an inductor or capacitor. The brace is constructed from a material structurally responsive to a predetermined stimulus, such that stimulus-responsive structural alterations to the brace structurally alters the inductor, capacitor, or other RFID subcomponent of the RFID circuit capable of generating a current alteration, which in turn alters the signal frequency of the RFID.
