  • Publication number: 20070121967
    Abstract: A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallel to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB.

  • Patent number: 7002562
    Abstract: A display made from a display panel and a circuit board that are surface mounted to one another. The surface mount interconnections may be distributed across the display avoiding the need to situate the contacts around the periphery. Particularly, in large area displays made up of a plurality of abutting displays, making interconnections in the peripheral areas may be disadvantageous. The row and column contacts may be redundant to improve the yield and life time of the display. Contacts adjacent edges may be displaced into available space, spaced away from the edges.

  • Patent number: 6743069
    Abstract: An electronic device having an extensive narrow passageway may be effectively encapsulated by forming openings in one or more of the surfaces defining the encapsulation region. Encapsulation material may then be injected through these openings to fill a narrow, difficult to access region between two surfaces being encapsulated. In some cases, the encapsulant may be applied progressively, starting with a central port and applying the encapsulant in a radially expanding front through radially displaced ports.

  • Patent number: 6706556
    Abstract: A non-planar surface may be surface mounted to another surface using solder balls that may be modified to generate a planar surface for receiving the second surface. In one embodiment, the solder balls may be secured to an irregular surface and then scrapped to form a planar contacting surface. A second surface to be bonded to the first surface may then be attached to the planar contacting surface and the solder balls reflowed to create a surface mount.

  • Patent number: 6653009
    Abstract: Solid oxide fuel cells made by coating a slurry of an electrolyte having a limited amount of organic material onto a carrier tape, depositing a one or two layer electrode material on the tape sufficient to support the electrolyte layer, removing the tape, screen printing a second electrode layer on the exposed surface of the electrolyte layer, and firing the layers at a temperature of 1100-1300° C. The resultant fired fuel cell can be mounted on an interconnector comprising a base plate, grooves formed in one face of the base plate, a porous conductive ceramic contact layer between the base plate and an overlying blocking layer of a porous conductive layer to provide electrical contact between the base plate and the blocking layer, or an interconnector having a fired green tape stack having conductive via contacts and air and gas flow channels formed therein. A sealing glass bonds the overlying layers to the base plate.
