Wireless Swimming Pool Water Level System

View page
US Patent:
6568264, May 27, 2003
Filed:
Feb 23, 2001
Appl. No.:
09/792456
Inventors:
Charles E. Heger - Saratoga CA, 95070
International Classification:
G01F 2300
US Classification:
73304, 340618
Abstract:
A wireless (e. g. , radio) system and method for automatic water level maintenance of, e. g. , a swimming pool utilizing capacitive liquid level sensing. A reference electrode allows water level sensing independent of the water chemistry or temperature. Capacitive electrodes having areas larger than the reference electrode sense various liquid levels when the liquid covers an area of any sensing electrode equal to the area of the reference electrode. Averaging is incorporated to filter out effects of wind or other disturbances. Upon sensing a given condition, the transmitter transmits a sensed condition to a remote receiver for control of valves and pumps for changing the water level in the pool. The receiver includes safety timers for filling and emptying to protect against equipment failure or communications faults. User selectable identification allows identical such radio systems to operate within proximity to each other.

Apparatus And Method For Capacitive Level Sensor

View page
US Patent:
6922063, Jul 26, 2005
Filed:
Jul 11, 2003
Appl. No.:
10/618403
Inventors:
Charles E. Heger - Saratoga CA, US
Assignee:
Zircon Corporation - Campbell CA
International Classification:
G01R027/26
US Classification:
324658, 324660, 33291
Abstract:
A capacitive sensor including a pendulum for electronically determining an indication of angular offset and a capacitive leveling device having such a capacitive sensor for leveling an associated reference surface. The capacitive sensor detects a difference in capacitance of one or more capacitors on the pendulum and its housing, each capacitor having a first electrode movable apart from a second electrode as the housing tilts relative to the pendulum.

Sensor Auto-Recalibration

View page
US Patent:
6989662, Jan 24, 2006
Filed:
Apr 29, 2004
Appl. No.:
10/835654
Inventors:
Charles E. Heger - Saratoga CA, US
Lawrence F. Miller - Los Gatos CA, US
Assignee:
Zircon Corporation - Campbell CA
International Classification:
G01R 27/26
G01R 19/00
US Classification:
324 67, 324202
Abstract:
A sensor and method that detects a mis-calibration and automatically recalibrates itself without operator intervention. If the sensor determines that it was calibrated over an object such as a stud, the sensor may automatically update the calibration value with a new lower value without operator intervention. This process may repeat until the calibration value is set to a value that represents the wall covering alone without hidden objects behind it.

Modular Laser Layout System

View page
US Patent:
7181853, Feb 27, 2007
Filed:
Nov 4, 2003
Appl. No.:
10/701940
Inventors:
Charles E. Heger - Saratoga CA, US
Norman L. Krantz - San Jose CA, US
Lawrence F. Miller - Los Gatos CA, US
Charles J. Stauss - Los Gatos CA, US
Assignee:
Zircon Corporation - Campbell CA
International Classification:
G01C 15/00
US Classification:
33286, 33281
Abstract:
A light emitting module and a modular light emitting system with leveling capability. The system relates to light-based (e. g. lower-based) layout tools of the type used in the construction industry. More specifically, the system relates to a modular light emitting system for projection visible patterns, such as dots, lines, cross-lines and other patterns, on one or more distant surfaces for purposes of alignment, construction, verification and the like.

US Patent:
7318344, Jan 15, 2008
Filed:
Mar 21, 2003
Appl. No.:
10/394947
Inventors:
Charles E. Heger - Saratoga CA, US
Assignee:
Heger Research LLC - Saratoga CA
International Classification:
G01F 23/26
US Classification:
73304C, 73304 R, 340612

Ratiometric Ac Wire Tracer

View page
US Patent:
7671576, Mar 2, 2010
Filed:
Mar 3, 2009
Appl. No.:
12/397241
Inventors:
Charles E. Heger - Saratoga CA, US
Richard Halliday - San Jose CA, US
International Classification:
G01R 19/00
US Classification:
324 66, 324 67
Abstract:
An implementation of an apparatus and method for sensing electrical wiring, for example, hidden behind a surface such as a wall is provided. The apparatus and method use multiple sensor signals, which may measure electric fields or changes in a dielectric. Pairs of signals are combined and compared to a sensed reference signal. Multiple sensors help in determining a direction or gradient to electrical wiring. Combining or averaging sensed signal before comparing the combined signal to a reference single helps to make the detection of electrical wiring less dependent on the relative orientation between the sensor and the electrical wiring.

Power Cable Magnetic Field Sensor

US Patent:
7714567, May 11, 2010
Filed:
Jun 22, 2008
Appl. No.:
12/143804
Inventors:
Charles E. Heger - Saratoga CA, US
Assignee:
Heger Research LLC - Saratoga CA
International Classification:
G01R 1/20
US Classification:
324126, 324117 R
Abstract:
A method and apparatus to detect non-cancelled magnetic field produced when current flows through an electric conductor are provided. The sensor includes multiple coils, which allow the sensor to be arbitrarily oriented and attach to the outside of an electrical power cable. Arbitrary orientation provides for easy of field installation.

Method For Locating Energized Electric Conductor

View page
US Patent:
20010010460, Aug 2, 2001
Filed:
Apr 9, 2001
Appl. No.:
09/832244
Inventors:
Lawrence Miller - Los Gatos CA, US
Charles Heger - Saratoga CA, US
International Classification:
G01R019/00
G01V003/10
US Classification:
324/067000, 324/326000
Abstract:
A single-sensor measurement system for detection and location of an AC signal emanating from a concealed energized electric conductor. A calibration routine of a measurement process carried out by the instrument first determines the background signal level of the AC signal at an initial position of the instrument. A second AC signal level is measured at a second location. The second signal level is compared with the background signal level. A signal indicating the presence of the energized electric conductor is generated by the instrument when the comparison result is greater than or equal to a predetermined value. The instrument initially positioned directly over a concealed energized electric conductor is automatically re-calibrated when a decrease in the AC signal level of a predetermined amount is detected. The electric field sensor is directly printed on the inside bottom panel of the instrument case and over the raised portions formed on the inside bottom panel. Electrical contact is made between the electric field sensor and the associated circuitry on a PCB in the case when the instrument is assembled.
