Title: Differential boxcar integrator with auto-zero function
Inventor: CHU CHING
IPC: H04B10/07
Filed: 1994-02-17
Abstract: ABSTRACT OF THE DISCLOSURE          A switched boxcar integrating circuit suitable for use with high speed data acquisition systems such as an Optical Domain Reflectometer. The boxcar integrator comprises a differential pre-amplifier stage, a sampling switch, and an integrator. The sampling switch couples the output of the pre-amplifier to the input of the integrator. The integrator includes non-inverting and inverting stages for producing a differential integrated signal. The switch samples the output of the pre-amplifier. The samples are integrated by the integrator once a sufficient number have been acquired. The sampling switch includes a switch controller to synchronize the operation of the switch with the received signals. The integrator also includes an offset compensator and a reset switch which are coupled to the integrator. The offset compensator and reset switch set the integrator to zero and also correct any offset error. A feature of the boxcar integrator according to the present invention is the variable integrator aperture which allows the response of the receiver stage in an OTDR to be matched to the characteristics of the transmit stage.

Title: Turbo oxidation system (tos) for "wet combusion" of cod-containing liquids and for cod-reduction by enzymes
Inventor: FONGEN SIGURD
IPC: C02F11/08
Filed: 1992-04-10
Abstract: The patent claims concern a method for a more efficient "wet combustion" of COD-containing effluents from industrial processes and municipal plants and for a more efficient COD-reduction by enzymes in aerobic and anaerobic biological cleaning processes and for same sorts of effluents. The method implies a strong increase of the reaction speed between added oxygen and the elements in the liquid to be oxidized through so-called "Turbo Oxidation", which implies that the liquid is submitted to strong movements and turbulence during several circulations within one or more liquid circuits during continuous addition of oxygen. By the same method, COD reduction by enzymes can also be made more effective. The single circuit is placed in connection to and communicates liquid-wise with a pressurized reaction tank, from where the developed reaction gases are continuously let out. Into the circuits and the attached reaction tank is continuously fed controlled quantities of the liquid to be oxidized together with proportionate quantities of oxygen or enzymes. Concurrently, the outlets of respectively oxidized liquid and evolved gases are controlled automatically.  Out-going, oxidized liquid can be heat exchanged against in-going liquid, and the hot gases from the reaction tank can be used for external, heating purposes.

Abstract: Improved Apparatus and Method for Water Heating Control Abstract A water heating system, including both a conventional water heater and an external heat source such as a heat pump, is controlled in accordance with the present invention. The water heater includes a water storage tank, an electrically resistive heating element located in the tank, and a tank-mounted thermostat which closes in response to a demand for water heating to allow electric current flow to the heating element and which opens when the demand for water heating has been satisfied, to interrupt the electric current flow to the heating element. The external heat pump includes a water pump for circulating the water between the storage tank and the heat pump, whereby water is heated by the heat pump and returned to the tank. A current sensor is provided for sensing the flow of electric current to the heating element and a temperature sensor is located external to the water storage tank for sensing the temperatureof the water entering the heat pump before the water is heated thereby. When the current sensor senses a flow of electric current to the heating element, thecurrent flow is interrupted so as to disable the heating element and the heat pump is enabled to provide the primary source of heating. The heat pump is operated until the temperature of the incoming water exceeds a predetermined set temperature. When this conditions occurs, the heat pump is deactivated and the heating element is enabled for a predetermined period to satisfy any additional water heating demand. The heating element is therefore used only to "boost" the water temperature to the desired temperature if the heat pump has not heated or is unable to heat the water to the required temperature.

Title: Conservation of water in operating evaporative coolers
Inventor: KOCIB SIDNEY ZDENEK
IPC: F25B19/00
Filed: 1994-06-17
Abstract: Cooling systems to reduce the dry-bulb temperature of ambient air by exchange of heat energy between air and water are popular for their low electric energy demand. In their operation, however, larger volumes of water have to be continuously drained to maintain the content of dissolved hard water minerals on a safe level. One method of this invention provides for reduced continuous discharge of process water, when specific chemical agent is employed, conserving thus precious drinking water. The other described method of invention, using another blend of chemicals, provides for manual, or for automatic operation of evaporative cooler, featured without continuous draining of circulating process water, and the volume of conserved water in this method is the largest possible. Selection of chemicals for best results in conserving water by these two methods is provided, and inexpensive, simple device for controlled introduction of chemical agent is also presented.

IPC: A61N1/39
Filed: 1995-03-27
Abstract: An atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion.          The defibrillator includes an electrode pair and a sense amplifier associated with the atria of the heart for sensing electrical activity of the heart during a plurality of cardiac cycles to provide a cardiac signal.  A detector is responsive to the cardiac signal for detecting cardiac events.  During each cardiac cycle of the plurality of cardiac cycles, a time for counting is established wherein each time for counting has a total duration less than the duration of its corresponding cardiac cycle.  A counter counts the cardiac events detected by the detector during the time for counting of the plurality of cardiac cycles to provide a cardiac event count.   A comparator compares the cardiac event count to a predetermined cardiac event count.  If the cardiac event count is greater than the predetermined cardiac event count, the atria are deemed to be in fibrillation and a cardiovertor applies cardioverting electrical energy to the atria to cardiovert the detected atrial fibrillation.
