Patent number: 6400995Abstract: A rodent control device generates a pulsating, interrupted electromagnetic field via one or more coil(s) and induces it onto the power line wiring in a building via core(s) linked to the coil(s). The rodent control device circuit is microprocessor controlled which allows automatic sensing of line voltage cycle rates and precise control of coil switching circuitry. The coil(s) are connected to the microprocessor to provide a coil monitoring signal via which the microprocessor detects abnormalities in the coil(s) such as shorts or open circuits. Upon detection of such an abnormality, the microprocessor shuts off control signals to the coil and to an LED indicator until a normal coil condition is sensed. The microprocessor also provides a timed rest signal for shutting down the device for, for example, 2 minutes out of every 6 minute period as a power saving feature.Type: GrantFiled: May 10, 1999Date of Patent: June 4, 2002Assignee: Global Instruments Ltd.Inventors: Charles R.

Patent number: 6389331Abstract: A facilities management system is subdivided into a plurality of subsystems. The performance of the system is monitored by producing data which denotes a plurality of operational parameters for each of the subsystems. From that data, a global performance index is derived for each subsystem, thus providing an indication of each subsystem's performance. The global performance indices are employed to produce a universal performance index for the entire facilities management system. This provides a hierarchy of data which enables an operator to quickly determine the overall performance of the facilities management system and each subsystem, and if warranted the operator can step through the data to identify malfunctioning components.Type: GrantFiled: March 11, 1999Date of Patent: May 14, 2002Assignee: Johnson Controls Technology CompanyInventors: Howard A.

Patent number: 6385500Abstract: The present invention relates to an improved servomechanism for regulating the spark gap in micro electrical discharge machining (micro-EDM). The present invention utilizes a hybrid two actuator servo system for positioning the micro-EDM electrode. The hybrid system comprises a fast, easily controllable, short stroke actuator (such as a piezoelectric actuator) for good instantaneous response, and a second, slower actuator for positioning the fast actuator and for providing the required long stroke. This allows the slower actuator to “feed” the electrode into the work-piece utilizing its long stroke, and the fast, short stroke actuator to respond quickly to instantaneous variations in the spark gap, such as short circuits.Type: GrantFiled: April 16, 1999Date of Patent: May 7, 2002Assignee: Cummins Engine Company, Inc.Inventors: Rajadasa R.

Patent number: 6385496Abstract: A generic process control routine for a process control system is written to include alias names and dynamic reference parameters. Before execution of a process control function on a particular unit of the process control system, an instance of the generic routine is created, in which the alias names are replaced by parameters defined in an alias resolution table for the particular unit. The controller then executes the instantiated version of the generic routine to control operation of the unit. The generic routine can have multiple algorithms associated therewith, wherein each of the algorithms is designed to control different units having somewhat different hardware, even though these different units perform essentially the same function within the process control system. The generic routine may also be used with multiple classes of hardware that perform different functions within the process control system.Type: GrantFiled: March 12, 1999Date of Patent: May 7, 2002Assignee: Fisher-Rosemount Systems, Inc.Inventors: William G. Irwin, Robert B. Havekost, Dennis L. Stevenson, David L. Deitz
