US Patent:

20030185171, Oct 2, 2003

Filed:

Mar 28, 2002

Appl. No.:

10/108620

Inventors:

Aaron Mullins - Hurst TX, US
John Ruppel - Keller TX, US

Assignee:

MOTOROLA, INC.

International Classification:

H04Q007/00

US Classification:

370/329000, 370/503000

Abstract:

An apparatus and method thereof for selectively transmitting a traffic channel signal or a beacon signal, the apparatus comprising in combination: a base band processor for providing a base band signal that selectively comprises one of traffic information and beacon information; a local oscillator (LO) source for providing a LO signal that is selected from one of a traffic LO signal and a beacon LO signal; a modulator, coupled to the LO signal, for converting the base band signal to a radio frequency (RF) signal; and an amplifier for amplifying the RF signal to provide a transmit signal that selectively corresponds to one of the traffic channel signal and the beacon signal.

Filed:

Aug 28, 1987

Appl. No.:

7/091150

Inventors:

Aaron B. Mullins - Hurst TX
Michael H. Bartlett - Fort Worth TX

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

B23K 3102
H05K 900

US Classification:

228179

Abstract:

An EMI/RFI shield (10) comprises a box like structure formed of a metal integral member having a plurality of apertures (16) formed therethrough. The apertures (16) are of a size appropriate to substantially pass infrared energy (22) and to substantially block EMI/RFI energy (26). When placed on a substrate (18), infrared energy (22) can be utilized to reflow solder a device (19) encapsulated by the shield (10) to the substrate (18).

Appl. No.:

7/768470

Inventors:

Andrew T. Morrison - Bedford TX
Aaron B. Mullins - Hurst TX

Assignee:

Motorola, Inc. - Shaumburg IL

International Classification:

H05K 702

US Classification:

361400

Abstract:

A circuit carrying substrate (108) accommodates circuit components (102) with different coefficients of expansion and contraction from that of the circuit carrying substrate (108). Beneath the components (102) a plurality of slots (104) are formed so as to minimize the effects of the differing coefficients of expansion and contraction.

US Patent:

Filed:

Sep 30, 1986

Appl. No.:

6/913206

Inventors:

Aaron B. Mullins - Hurst TX

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H05K 900

US Classification:

174 35R

Abstract:

Disclosed is an improved housing being comprised of a substrate and a cover that is plated to provide RF shielding. The substrate and cover are constructed of a like material to keep the coefficients of vibration approximately identical. Preferably, the substrate and cover material are ceramic thereby providing a rigid structure that minimizes vibration degradation.
