Title: Systems and methods for extending the useful life of optical sensors
Inventor: COLVIN ARTHUR EARL JR
IPC: G01N21/64
Filed: 2005-04-25
Granted: 2014-08-19
Abstract: The present invention provides a method for increasing the lifetime of an optical sensor. In one aspect, the method includes the step of configuring the optical sensor so that the duty cycle of sensor's radiant source is less than 100% over a continuous period amount of time when the sensor is periodically obtaining data regarding an analyte. By operating the sensor according to the above inventive method, the indicator molecules of the optical sensor are not excited during the entire continuous period of time during which the sensor is needed to provide data regarding the presence or concentration of a substance.  Thus, the method increases the life of the indicator molecules.

Title: Method and system for coating internal surfaces of prefabricated process piping in the field
Inventor: BOARDMAN WILLIAM JOHN
IPC: C23C14/00
Filed: 2005-07-06
Granted: 2010-11-02
Abstract: The coating of internal surfaces of a workpiece is achieved by connecting a bias voltage (20 and 47) such that the workpiece functions as a cathode and by connecting an anode (22 and 24) at each opening of the workpiece. A source gas (16 and 18) is introduced at an entrance opening, while a vacuum source (32) is connected at an exit opening. Pressure within the workpiece is monitored (34) and the resulting pressure information is used for maintaining a condition that exhibits the hollow cathode effect. Optionally, a pre-cleaning (52) may be provided by introducing a hydrocarbon mixture and applying a negative bias to the workpiece, so as to sputter contaminants from the workpiece using argon gas (16). Argon gas may also be introduced during the coating processing to re-sputter the coating, thereby improving uniformity along the length of the workpiece. The coating may be a diamond-like carbon material having properties which are determined by controlling ion bombardment energy.

Title: A hydroelectric powerplant
Inventor: WILLIAM HERBERT LEHMAN
IPC: F03B3/04
Filed: 2004-01-21
Granted: 2012-09-04
Abstract: A powerplant for use in high head applications (dams) which allows marine animals (fish, otters, turtles, etc.) to swim safely from one side of the dam to the other. The turbine blades which take energy from the water to produce electricity have a large hole through their center. They are arranged one behind the other in such a way that the velocity of the water is decreased as it passes through each blade. The large holes through the center of the turbine blades and the decreasing of the water flow, while increasing the amount of energy produced, will allow marine life to easily swim back and forth through the dam.

Title: Burner flashback detection and system shutdown apparatus
Inventor: PEART JACOB A
IPC: F23K5/16
Filed: 2008-04-04
Granted: 2011-03-22
Abstract: A fuel-fired water heater is provided with a premixing type main burner and an associated pilot burner for igniting it. A specially designed protective system is operative to detect a flame flashback burning condition in the main burner and responsively shut down the water heater. In one embodiment thereof, the protective system uses main burner body heat to melt a portion of a fuel supply line connected to the pilot burner during a flame flashback condition in the main burner. Such melting responsively causes an associated fuel supply valve to close and terminate water heater operation. In a second protective system embodiment a normally closed pressure switch is opened, thereby shutting down the water heater, when the switch detects a pressure indicative of a flame flashback condition in the main burner.
