  • Patent number: 8331931
    Abstract: A method and system for registering wireless devices with a base unit that is configured to communicate wirelessly with multiple wireless devices. In one example, the wireless devices are cordless handsets of cordless telephone systems. When placed in a charging cradle, an unregistered handset displays a message indicating that the handset should be registered. A user provides local input to the base unit to activate a registration sequence. A three-way handshake is initiated at the base station, wherein a sequence of three wireless messages are passed between the base and unregistered handset. The handset displays a message indicating successful registration.

  • Patent number: 4492825
    Abstract: A transducer embodying the present invention is assembled on a discrete electrically conductive frame (100) that has been formed to provide both leads (120-140) and a backplate (110). An integrated circuit chip (200) is bonded to one of the leads, and a dielectric inner housing member (300) is molded about the backplate and the portion of the leads adjacent to it. The inner housing member encapsulates the chip, embraces the perimeter of the backplate, and provides a cylindrical opening (310) that extends on each side of the backplate. A conductive outer housing member (400) is subsequently molded about the perimeter of the inner housing member, and a spacer (500), electret diaphragm assembly (600), and conductive gasket (700) are sequentially positioned in the opening on one side of the backplate. Conductive front and back covers (800,900) are thereafter bonded to the outer housing to close the opening and to complete a conductive enclosure that provides electrostatic shielding for the transducer.
