US Patent:

20030074780, Apr 24, 2003

Filed:

May 16, 2001

Appl. No.:

09/859180

Inventors:

Robert Doran - Apex NC, US
Shawn Stephenson - Raleigh NC, US

Assignee:

Ericsson Inc.

International Classification:

H01R004/58

US Classification:

029/600000

Abstract:

A mobile terminal employs existing geometry such as a rear housing or shield box to carry a radiating element. This element is made of a flexible elastomer with a conductive filler. The element is applied by dispensing using a syringe type operation, where it would be squirted on the geometry or the part placed in a secondary injection mold tool. This tool would have the pattern as open volume in the steel that would allow the conductive elastomer to fill out the pattern and adhere to the part. The radiating element is flexible and conforming, simplifying the design by reducing additional carrying components, simplifying the tolerance chain and makes full use of the surface area.

Appl. No.:

8/895970

Bart Reier - Raleigh NC

Ericsson, Inc. - Research Triangle Park NC

International Classification:

H01H 1370

US Classification:

200343

Abstract:

An actuator button is mounted in a housing by a cantilevered beam fixedly attached to the intermediate portion of a torsion beam. The ends of the torsion beam are nonrotatably fixed with respect to the housing. The actuator button is maintained at a normal, spaced-apart position with respect to a switch positioned within the housing. Movement of the actuator toward the switch induces bending stress in the cantilevered beam and torsional stress in torsion beam. The actuator button arrangement permits direct, vertical insertion of the actuator button into the housing, does not require any secondary assembly operations, and has a unitary construction.

International Classification:

H04B 138

US Classification:

Abstract:

A sensor unit for an electronic device having a pivotable cover member includes a signal emitter, a signal receiver spaced from the signal emitter, and a baffle attached to the cover member and disposed in the space between the signal emitter and the signal receiver when the cover is in its closed position. A transmit window disposed between the signal emitter and the signal receiver is permeable to signals falling within a specified wavelength range, thereby ensuring the accuracy of the signal. When the sensor unit is applied to a cellular phone, for example, the phone can be automatically in an "off hook" or "on hook" condition automatically in accordance with whether the cover member is in its open position or closed position, and an operator need only perform a single operation to answer or terminate a call or to power up the phone.
