Abstract: Measured position data (Px, Py, Pz) are combined with stored correction values (DB) describing the elastic bending behavior of a coordinate measuring machine in that parameters characterizing the bending behavior are determined for several positions of the probe of the machine within the measuring range (30) of the machine, the acceleration-dependent components of these parameters are determined and stored in the form of correction values (c11, c22) which describe the bending behavior of the coordinate measuring machine as a function of the position (Px, Py, Pz) of measuring slides (22, 23, 24), and at least of the acceleration (ax, ay, az) of the measuring slides introduced via the drives, the correction values being combined with measured position data (Px, Py, Pz) of the coordinate measuring machine in subsequent coordinate measurements on workpieces.

Abstract: An intelligent wall switch incorporates a passive infrared sensor and a pressure pulse-wave sensor. A microcontroller monitors the sensor signals generated by the infrared sensor and the pressure pulse-wave sensor and calculates a weighted sum of the signals generated by the sensors. If the weighted sum calculated by the microcontroller exceeds a preset threshold the intelligent wall switch generates a signal indicative of human presence.

Abstract: A method of rational drug design includes simulating polypeptides in a way that predicts the most probable secondary and/or tertiary structures of a polypeptide, e.g., an oligopeptide, without any presumptions as to the conformation of the underlying primary or secondary structure. The method involves computer simulation of the polypeptide, and more particularly simulating a real-size primary structure in an aqueous environment, shrinking the size of the polypeptide isobarically and isothermally, and expanding the simulated polypeptide to its real size in selected time periods. A useful set of tools, termed Balaji plots, energy conformational maps, and probability maps, assist in identifying those portions of the predicted peptide structure that are most flexible or most rigid. The rational design of novel compounds, useful as drugs, e.g., bioactive peptidomimetic compounds, and constrained analogs thereof, is thus made possible using the simulation methods and tools of the described invention.

Abstract: A plant with a gas turbine such as a combined cycle power plant of a gas turbine cycle and a steam turbine cycle is provided with a nitrogen oxide removal device for removing NO.sub.x by injecting ammonia to an exhaust gas of the gas turbine. The device reduces NO.sub.x concentration to a certain value or less before the exhaust gas is released to the air. An ammonia flow amount is rapidly controlled such that a mole ratio of ammonia to NO.sub.x coincides with a set mole ratio value. The mole ratio is calculated from a predicted NO.sub.x concentration at an inlet of the nitrogen oxide removal device predicted by calculating operation conditions of the gas turbine, an ammonia flow amount value, and an exhaust gas flow amount. The set mole ratio value is calculated from a deviation of a measured NO.sub.x concentration value at an outlet of the nitrogen oxide removal device and a set NO.sub.x concentration value, and an amount of water injected to a combustor.

Abstract: An energy management and building automation system including a local area network or home automation data bus such as the CEBus. Each load is connected to the bus via a control module which may contain a circuit breaker to disconnect the load from the mains upon command or upon occurrence of a power outage. Current monitoring control modules measure load current and power monitor modules monitor power consumed by selected loads, both modules transmitting bus messages indicating load status and status changes. A first microcomputer preferably is external to the customer premises, adjacent the electric utility power meter. A second microcomputer preferably is inside the customer premises. The two microcomputers communicate with each other and with the various modules via the network/data bus. The first microcomputer communicates with the utility company via any appropriate communications link.

Abstract: A voltage regulator controller of a step-type voltage regulator monitors its own power supply and saves the regulators operations count to a non-volatile memory, only when it is determined that a power failure is imminent. The controller counts the number of tap changes in the voltage regulator transformer by monitoring an "operations counter" signal from the regulator's tap changer mechanism. When a tap change is detected, the controller increments an electronically stored count value. The electronically stored count value is maintained exactly, even when the power to the device is lost. In order to determine whether a power failure is imminent, the controller monitors the AC supply voltage using a zero-crossing detector circuit. The zero crossing detector circuit produces transitions corresponding to transition in the AC power waveform. The zero crossing circuit stops producing transition when the AC voltage falls below a predetermined threshold.

Abstract: The method is to detect a fault on a busbar and to specify the faulted point to a specific section of the busbar in order to provide a proper protection. If the fault has occurred, for instance, on a point P of a section between current transformer BCT- and a connecting point thereof to the busbar, or on a point Q of a busbar section between adjacent line outlets, the resulting fault current is expressed as a calculation sum of an output current of the current transformer BCT-. The foregoing current is zero in a normal condition, but in case of a fault, it reaches a definite value other than zero. Noticing this point, the fault current is computed for each section on the basis of the observable output current of the current transformer BCT-, and it is judged that if the foregoing current of a specific section exceeds a predetermined threshold, the fault has occurred on the above section.

Abstract: The present invention provides a constrained stochastic dynamical method for simulating the motion of a molecular system. The method simulates the motions of atoms within the molecular system by evaluating first order force expressions for all the atoms over a series of time steps. The force expressions include terms for frictional forces, non-covalently interatomic forces, thermal noise forces, and covalent constraining forces. Relatively long time steps can be used because the fast motions (such as vibrations associated with covalent bonds) are not explicitly considered. Rather, the fast molecular motions associated with covalent bonds are averaged around their equilibrium bond lengths and, in some cases, bond angles. This is implemented by introducing (1) thermal noise forces, and (2) constraining forces fixing the relative positions of some atoms based upon their covalent bonds.

Abstract: A device for quickly and accurately testing an electronic vehicle engine control module having a simulated signal generator for supplying simulated or "dummy" input signals to the module under test. These simulated signals correspond to signals normally generated by peripheral automotive components such as mass air flow sensors, throttle position sensors, oxygen sensors, and the like, in proper working order. A simulation program controls the simulated signal generator and causes the simulated signal generator to generate predetermined signals appropriate to the design of the module and specific to the simulated operating conditions under which the module is being tested. The simulation program also contains acceptable ranges of output values (that should be produced by a property operating module) corresponding to the simulated operating conditions defined by the simulation program.

Abstract: An unbounded marker for a swept-tuned analyzer is adjusted by an operator. The frequency of the unbounded marker can be controlled by the operator in three ways, namely, by turning a knob, by pressing UP and DOWN step keys, or by entering a frequency for the unbounded marker using a numeric key pad. The knob continuously adjusts the tune frequency of the analyzer when the unbounded marker reaches the upper or lower boundary of the frequency span. At the high end of the frequency span, the knob continuously re-tunes the start and stop frequencies higher in frequency. At the low end of the frequency span, the knob continuously re-tunes the start and stop frequencies lower in frequency. The unbounded marker remains at the edge of the trace. At the boundaries of the frequency span, the UP and DOWN step keys re-tune the analyzer by a step, the size of which is equal to the frequency span, and the unbounded marker is positioned at the edge of the trace. When the analyzer is fixed tuned to a given frequency, i.e.

Abstract: A method for determining a length, especially for determining an overlap length of a wound strip of material, is provided. In order to be able to automatically determine the overlap length it is suggested that the forward end of a strip of material applied to a winding drum is detected by a detector and, simultaneously, the corresponding angular position of the winding drum is measured. After the completion of the winding of the strip of material, its rearward end is detected by the detector and, simultaneously, the corresponding angular position of the winding drum is measured. Subsequently, a difference between the angular positions of the winding drum is used to determine the length of the strip of material.

Abstract: A small size apparatus for measuring and recording acceleration comprises an acceleration sensor, an A/D converter which converts the output signal of the acceleration sensor to a digital signal, a control element which processes the digital signal, a detachable external memory device which stores data of a change in acceleration and, a battery for supplying electric power to the sensor, the A/D converter, the control element and the external memory device. The small size apparatus is mounted on a moving body to be measured and the entire small size apparatus is driven by the battery. The correct attachment of the external memory device is detected by steps of writing data into a special address, reading the data out thereafter, and comparing the written data and read data. When the read data coincides with the written data, it is judged that the external memory device is correctly attached.

Abstract: An x-ray inspection machine particularly suited for use on an assembly line has a narrow footprint produced by mounting opposed x-ray tube and camera on independently movable stages locked together by way of a central computer rather than a physical member. The stages are aligned by using position sensors at home positions and a fiduciary mark on the part to be inspected. The independent motion of the stages permits a limited range of angled inspections to be obtained without additional angulation mechanisms.
