Publication number: 20150372357Abstract: A magnesium fuel cell with removable anodes and cathodes wherein the cathodes are enclosed in flat or curved frames or fixtures that are easily replaceable when damaged. The cathodes are designed to be particularly durable for heavy use. Multiple redundancies are incorporated that make the fuel cell less likely to fail and more suitable for use in places where other power sources are not available. The fuel cell is adapted for long use at low voltage levels and with a secondary battery with higher voltage that is continuously charged that in turn, can be used to charge other batteries.Type: ApplicationFiled: June 23, 2014Publication date: December 24, 2015Inventors: Ivan Theodore Kruglak, Mark Dansie, James Rodney, Hugh P.

Frequency modulated ballast with loosely coupled transformer for parallel gas discharge lamp control
Patent number: 6181066Abstract: A frequency dependent controller utilizes a loosely coupled transformer, adapted to change the operating characteristics of the transformer by varying its operating frequency in accordance with the requirements of a load to be supplied with power. The controller is particularly adapted for dimming and adjustably controlling a set of gas discharge lamps such as fluorescent lamps, connected in parallel such that failure of one lamp does not affect operation of the other lamps in the set.Type: GrantFiled: September 30, 1998Date of Patent: January 30, 2001Assignee: Power Circuit Innovations, Inc.Inventor: Hugh P. Adamson -
Patent number: 6094017Abstract: A dimmer ballast or output drive circuit and a drive method for a high intensity discharge lamp utilizes an overwound loosely coupled transformer having a turns ratio of preferably about one to one with a peaking capacitor across the secondary output terminals of the transformer and in parallel with the HID lamp arc electrodes. A control circuit provides a variable frequency drive voltage to the primary of the transformer. The frequency of the output voltage is adjustably controlled above the peak load power frequency. The load power and hence the light output of the lamp varies according to the frequency of the output voltage permitting a user to adjustably dim the high intensity discharge lamp.Type: GrantFiled: September 30, 1998Date of Patent: July 25, 2000Assignee: Power Circuit Innovations, Inc.Inventor: Hugh P.

Patent number: 4965572Abstract: A method for producing a warning of the existence of low-level wind shear and an aircraftborne system for performing the method utilizes measured values of airspeed and temperature, to determine a temperature based hazard factor relating to the existence of a wind shear threat to the aircraft and to issue a warning whenever the hazard factor exceeds a predetermined threshold level based upon the performance characteristics of the aircraft. Temperatures may be sensed locally, such as by a resistive temperature sensor or, remotely, such as by an infrarred temperature detector. Furthermore, in accordance with preferred embodiments, an inertial reactive wind shear detector is utilized as an integrated safety measure. Moreover, the threshold level may be varied depending on such factors as aircraft altitude.Type: GrantFiled: June 10, 1988Date of Patent: October 23, 1990Assignee: Turbulence Prediction SystemsInventor: Hugh P.

Patent number: 4728877Abstract: An electrochemical process and apparatus utilizing a positive and negative electrode. A current is periodically provided in a first direction between the electrodes through the electrolyte of the electrochemical process. The direction of the current is periodically reversed through the electrolyte to repolarize the electrodes, to at least decrease the electric double layer at the electrodes, and to exercise the electrolyte. The current is changed in response to voltage changes occuring across the electrodes caused by perturbations in the electrochemical process itself where the slope of the function representing the current change with respect to a voltage change caused by the perturbations is sufficiently large to enhance the repolarizing, the decreasing of the electric double layer and the exercizing of the electrolyte to thus effect improvement in the electrochemical process.Type: GrantFiled: June 10, 1986Date of Patent: March 1, 1988Assignee: Adaptive Instruments Corp.Inventor: Hugh P. Adamson

Patent number: 4427306Abstract: A radiometer apparatus is described that is particularly useful for detecting clear air turbulence by sensing infrared radiation. The radiometer includes optics for directing infrared radiation past a chopper, lens and infrared filter assembly to a radiation sensor which produces an analog output signal that is routed through an N-path filter unit and then demodulated and integrated by an averaging integrator to produce temperature indicative differences for determination of the presence of clear air turbulence in the area then being examined by the apparatus, the N-path unit and averaging intergrator providing a high signal to noise ratio. An automatic calibration unit is also provided to provide stability and reliability to the apparatus.Type: GrantFiled: August 4, 1980Date of Patent: January 24, 1984Assignee: University Patents, Inc.Inventor: Hugh P.

Patent number: 4342912Abstract: Apparatus is described for detecting air disturbances created by low level wind shear. The apparatus includes optics for directing infrared radiation towards a continuously rotating chopper wheel having a plurality of infrared filters which have effectively different distance sensitivities and therefrom to a radiation sensor which produces an analog output signal that is demodulated by a synchronous demodulator. The demodulated signal is then routed through a gated integrator to a selective multiplexing circuit which has a plurality of output channels and is controlled by an electronic detector connected with the chopper wheel. Each channel includes a low pass filter and the outputs therefrom are coupled to a signal processor which thus receives periodically updated information to provide a display indicative of sensed air disturbances due to low level wind shear.Type: GrantFiled: August 4, 1980Date of Patent: August 3, 1982Assignee: University Patents, Inc.Inventor: Hugh P.
