Eletronic Flight Instrument
US Patent:
2009029, Dec 3, 2009
Filed:
Jun 2, 2008
Appl. No.:
12/131817
Inventors:
David Robert Stubben - Cameron Park CA, US
Todd Keller Sprague - Placerville CA, US
Todd Keller Sprague - Placerville CA, US
International Classification:
G07C 5/00, G01P 15/00, G01P 5/14
US Classification:
340945, 340974, 340977, 340978, 340979, 73488
Abstract:
A flight instrument, having an electronic display, is configured to fit within a standard instrument mount and within an array of standard instrument mounts. The instrument has the ability to emulate any standard or other instrument. This instrument can share its installed optional sensors with other instances of itself that do not include the optional sensors by way of network interfaces. The instrument can contain emulation for all standard instruments and have a menu to select which to display.
Apparatus And Method For Crane Game Claw Control
US Patent:
6283475, Sep 4, 2001
Filed:
Oct 19, 1999
Appl. No.:
9/421186
Inventors:
David R. Stubben - Cameron Park CA
Assignee:
Smart Industries Corporation - Des Moines IA
International Classification:
A63F 924
US Classification:
273448
Abstract:
An improved claw control system for use in a coin operated crane game. In one embodiment, this system allows operation of the claw solenoid in a precise manner in which the DC claw current is digitally controlled. A microcomputer can be used to read a potentiometer setting via an analog to digital converter. The microcomputer outputs a command current to the solenoid via a digital to analog converter and a solenoid driver.
Portable Leveling Table
US Patent:
2009029, Dec 3, 2009
Filed:
Jun 2, 2008
Appl. No.:
12/131864
Inventors:
David Robert Stubben - Cameron Park CA, US
International Classification:
G01C 9/00
US Classification:
702154
Abstract:
An automatic table leveling system includes a linear accelerometer, a microcontroller, motor drivers, motors and lead screws. The microcontroller reads linear accelerometer sensor information which indicates the table top's attitude with respect to the gravity vector. Then the microcontroller sends signals to the motor drivers to cause the motors to drive the table legs up or down via a lead screw mechanism. The changed leg lengths adjust the attitude of the table top to make it level.
