Apparatus For Recording Vehicle Position
US Patent:
5721540, Feb 24, 1998
Filed:
Aug 16, 1996
Appl. No.:
8/698784
Inventors:
David M. Ellis - Warren VT
International Classification:
G06G 1123
US Classification:
340988
Abstract:
The apparatus for recording vehicle position is designed to provide the user with a system for recording date, time and vehicle position utilizing information available from a Global Positioning System receiver. The recorded information is called a position log. The position log, in the form of a data file, can be transferred to a computer and reviewed at a later time. The apparatus contains devices which detect attempts at altering the position log, making the position log certifiably authentic and usable in legal proceedings. The apparatus has a Global Positioning System receiver, a clock, a microprocessor and independent vehicle motion sensing capability. The apparatus connects to the Global Positioning System antenna and the vehicle battery. All parts of the apparatus are enclosed in a sealed container which prevents alteration of the position log by substituting simulated Global Positioning System data for the real data in the position log.
Gust Compensated Total Energy Variometers
US Patent:
2013019, Aug 1, 2013
Filed:
Jan 30, 2013
Appl. No.:
13/753689
Inventors:
David Miller Ellis - Warren VT, US
International Classification:
B64D 45/00
US Classification:
701 6
Abstract:
Rise and fall rates for a glider are determined based on the glider's angle of attack and speed. These rise and fall rates are used to compensate a variometer so that the impact of vertical airmass flow can be used to optimize glider soaring. Altitude measurements are used to determine the glider's potential energy while velocity is used to determine the glider's kinetic energy. Total energy compensation techniques are then used to correct error calculations in the variometer.
Pulsed Thermistor Sensor
US Patent:
7201049, Apr 10, 2007
Filed:
Oct 27, 2004
Appl. No.:
10/974494
Inventors:
David M. Ellis - Warren VT, US
Rajesh M. Nair - Nashua NH, US
Rajesh M. Nair - Nashua NH, US
Assignee:
Degree Controls, Inc. - Milford NH
International Classification:
G01F 1/68
US Classification:
7320425, 7320411, 7320423, 7386195
Abstract:
A thermistor is pulsed with energy, and a time constant of decay of temperature is calculated based on measured resistance of the thermistor over a number of known intervals. The time constant is representative of the mass air flow. The ambient air temperature may be found without waiting for the thermistor to reach the ambient air temperature.
