  • Publication number: 20160182117
    Abstract: An apparatus for performing operations using low power, including control circuitry; a radio frequency (RF) circuit for receiving RF signals at one or more frequencies; an internal power source; and switching circuitry coupled between the control circuitry and the internal power source, the switching circuitry having a control terminal coupled to an output of the RF circuit.

  • Patent number: 9319093
    Abstract: An apparatus for shipping a device containing a circuit, including a bag sized for holding the device; and an antenna connected to the bag, the antenna having a first end for coupling to the circuit of the device when the device is in the bag so as to allow for radio frequency (RF) communication with the device while the device is in the bag. Separation of the device from the bag causes the antenna to be disconnected from the circuit of the device.

  • Publication number: 20150186694
    Abstract: A RFID based system, including an RFID tag to communicate with a reader and having a motion-based generator generating current upon the device being moved. When the object moves, the RFID tag is configured to transmit at least one signal to the reader using the current generated by the motion-based generator to indicate that the object is in use. The RFID tag may include an energy scavenging circuit such that the RFID tag is also capable of being interrogated by the reader and perform additional operations, independent of the motion-based generator.

  • Publication number: 20150173207
    Abstract: A method for forming a Z-directed component for insertion into a mounting hole in a printed circuit board according to one example includes filling a first cavity having a tapered surface with a body material. A first layer of a constraining material is provided on top of the first cavity and has a second cavity having a width that is smaller than the first cavity. The second cavity is filled with the body material. Successive layers of the constraining material are provided on top of the first layer of the constraining material. Cavities of the successive layers of the constraining material are selectively filled with at least the body material to form layers of the main body portion of the Z-directed component. The constraining material is dissipated to release the Z-directed component from the constraining material and the Z-directed component is fired.
