Abstract: A 2-element, three voltage connection electronic energy meter is disclosed for measuring 3-phase electrical energy supplied by a 4-wire delta service without external potential transformers. The meter employs non-isolating voltagesensors for sensing the line voltages and includes and an automatic service type detector and isolation detector. The meter generates voltage and phase angle measurements for each of the two voltages sensed by the meter. The service type detector compares the phase angles to automatically determine the service type supplying the electrical energy to the meter. The isolation detector compares the two voltages to automatically determine whether or not the installation includes external potential transformers. If the service type is a 4-wire delta service and no external potential transformers are used at the installation for isolating the voltage signals, the meter doubles the voltage measured over the first of the two elements when generating power measurements.

Abstract: In a FLIR/laser based targeting and imaging system, the ability to recognize, detect, locate, and/or track targets in an area of interest is significantly improved by reducing the fixed and dynamic alignment errors between the IR LOS and the laser LOS. Fixed alignment errors between the IR LOS and the laser LOS. Fixed alignment errors are reduced with an improved internal boresight module (Fig. 10) and corresponding boresight method. Dynamic alignment errors are reduced with an opto-electric subsystem that employs a single pitch (405) bearing and a common pitch/yaw afocal (401) for both the laser energy and the IR energy. A segmented window (Fig. 17) in the system housing includes a circular EMI grid pattern (Fig. 19) which significantly reduces the amount of off-axis EMI entering the optical pathways, and improved signal processing techniques (Fig. 26) are employed to enhance the quality of the IR image after the image has been digitized.

Abstract: A method for determining a volume fraction of water moving in a predetermined direction along a highly inclined conduit. The method includes measuring a fractional volume of water occupying the conduit at a plurality of locations along the conduit. An oxygen activation velocity of the water flowing in the conduit is determined at a plurality of locations along the conduit. A counting rate of a gamma ray detector used to measure oxygen activation is normalized with respect to the measured fractional volume of water. The normalized count rates of the gamma ray detector are characterized with respect to a relative velocity between the water and the detector. The step of characterizing is performed in portions of the conduit which are sloped so that gravity acts on the water along the predetermined direction. A fraction of the characterized counting rate represented by the oxygen activation counting rates measured along the conduit is determined. The fraction represents the fractional volume of water moving in the predetermined direction.

Title: Rotatable inverter
Inventor: SUNG HAN-JUN
IPC: H02M7/60
Filed: 1999-01-07
Granted: 2000-10-10
Abstract: Disclosed is a rotatable inverter. The rotatable inverter comprises a rotatable inverting means for inverting a DC power source to an AC power source by means of a rotational force, and a transformer which receives the AC power source inverted by the rotatable inverting means and outputs a higher voltage. The rotatable inverting means comprises a motor generating the rotational force, a commutator driven by the motor and a plurality of brushes which are respectively contacted with the outer surface of the commutator. The commutator comprises a cylindrical body made of an insulating material, and conductive parts which are divided into an even-number by non-conductive parts, respectively, having a desired width. Further, it is preferable that the cooling fan is coupled to the motor along with the commutator. Therefore, the manufacturing cost is lowered, the attrition rate of the current is lowered, the energy lost by heat is decreased, the size of the microwave oven can be smaller, and the output frequency from the rotatable inverter can be controlled to be kept constant and the microwaves are also more stably radiated.

Granted: 2003-12-30
Abstract: An electronic article security system (10) monitors articles (12) sold by a retail store (16) to detect shrinkage. The articles (12) are tagged with RF-ID  security tags (22). Each security tag (22) has a unique or semi-unique serial number for identifying individual products. Transaction records (36) generated from point-of-sale terminals in the store are sent to a remote computer (38).  An interrogator (42) and surveillance camera (58) are positioned near the store exit. When an article (12) having the RF-ID security tag (22) is detected as passing through the store exit, the interrogator outputs a signal derived from the security tag (22). The output signal includes the security tag serial number. Also, the camera (58) takes an image of the person moving the tagged article through the exit. The interrogator output signal is sent to the remote computer (38). The remote computer (38) periodically compares the transaction records (36) with the interrogator output signals to detect any discrepancies therebetween. The discrepancies are investigated by viewing the captured video images near the time of the discrepancies.

Abstract: To correct for any source of non-linearity and noise introduced in the power amplification of a pulse modulated signal, a correction unit is applied in-between the pulse modulator and the switching power amplification stage. The correction unit is controlled to have a compensating effect, by introducing continuous delays on the individual pulse edges on the basis of error information provided by an error processing block. One preferred embodiment of the invention comprises: a Correction Unit with means to control the delays of the individual pulse edges as a function of a control input signal v e; a state feedback block A with compensation; a reference shaping block R to modify the pulsed reference v r; for optimized error estimation; a difference block to generate an error signal and a compensator C to shape this error. The invention makes it possible to implement practical digital to analog power conversion, with efficient compensation of any non-linearity and noise introduced in the switching power stage and filter, such that great efficiency, high performance and low system complexity is combined. Applications are direct digital to audio power conversion and improved general DC-DC or DC-AC power conversion systems controlled from the digital domain.

Granted: 2003-04-15
Abstract: A power control device for a CDMA communication system using different kinds of spreading codes. In the power control device for a base station device, a first channel generator generates a first channel signal by spreading first input data (DATA1) with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data (DATA2) with a quasi-orthogonal code. The second channel signal has a gain higher than that of the first channel signal. A first gain controller (17) controls power of the first channel signal and a second gain controller (18) controls power of the second channel signal. An adder (20) adds the first channel signal to the second channel signal, and a spreader (21) spreads a signal output from the adder with a pseudo-random noise (PN) code. The base station transmits a response request message to a mobile station via the second channel, and retransmits the response request message after increasing a transmission power of the second channel when a response message is not received from the mobile station.
