Method For Communicating Between A Microprocessor And An Interface Circuit

US Patent:
5671375, Sep 23, 1997
Filed:
Dec 26, 1995
Appl. No.:
8/578763
Inventors:
Troy L. Stockstad - Phoenix AZ
Matthew F. Bacchi - Mesa AZ
Martin J. Brown - Scottsdale AZ
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
G06F 1300
US Classification:
395309
Abstract:
A protocol between a microprocessor (21) and an interface circuit (11). The interface circuit (11) transmits an enable signal (124) to the microprocessor (21). Upon receiving the enable signal (124), the microprocessor (21) transmits a set of pulses of a window signal (125) to the interface circuit (11), which in turn provides the microprocessor (21) with information concerning a circuit element (36) through a data signal (127). The microprocessor (21) initiates a command by transmitting a pulse of a command signal (126) to the interface circuit (11). The interface circuit (11) accepts and executes the command only if a predetermined chronological condition between the pulse of the command signal (126) and a corresponding pulse of the window signal (125) is satisfied. The microprocessor (21) identifies a malfunctioning interface circuit (11) by timing the enable signal (124) received from the interface circuit (11).

Flyback Power Supply Having A Vco Controlled Switching Rate

US Patent:
5390101, Feb 14, 1995
Filed:
Jan 4, 1994
Appl. No.:
8/177689
Inventors:
Martin J. Brown - Scottsdale AZ
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H02M 3335
US Classification:
363 20
Abstract:
A DC-DC current-mode controlled flyback switching power supply provides a high efficiency of operation throughout a wide range of input voltages. An error amplifier produces an error signal from the difference between a reference voltage and an output voltage feedback signal. The error signal controls a VCO that sets a latch to enable a power switch to store power in a flyback transformer. A comparator compares the error signal against a current sense feedback signal indicating the current flowing through the power switch. The comparator resets the latch and disables the power switch to transfer the stored energy in the flyback transformer to the output of the power supply. The extended input range of operation is achieved by varying the switching frequency of the DC-DC converter through the use of the VCO to accommodate varying input voltages and loading.

Device For Adhesively Holding Small Objects

US Patent:
4953902, Sep 4, 1990
Filed:
Sep 21, 1988
Appl. No.:
7/247403
Inventors:
Martin A. Brown - Fountain Hills AZ
International Classification:
A61C 300, B25J 1500
US Classification:
294 11
Abstract:
A porcelain veneer placement holder is provided for picking up a small porcelain veneer piece and placing it on a surface of a tooth. The holder includes an elongated handle having an end portion, a plunger fixedly connected to and cantilevered from the end portion, a hollow cylinder slidably mounted on the plunger and forming an open-ended variable-volume chamber containing an adhesive material. The adhesive material is extruded for making a small deposit at the top of the cylinder. The handle end portion has a peripheral wall cantilevered therefrom and is coaxial with the plunger along a plunger axis. The peripheral wall and the plunger form a cylindrical cavity therebetween, which receives the cylinder. The end portion and the plunger axis are disposed at an angle to the handle.
