Abstract: A calibration and compensation technique for an electrical compass, called the circular error calibration and compensation technique; the electrical compass comprises of a driver, a bearing angle sensor, transverse-longitudinal signal processor, transverse-longitudinal analog/digital converter, a microprocessor, an output device; the bearing angle sensor consists of a shell, a magnetic sensor ring, a set of spiral drive coil wound around the shell, and two sets of transverse and longitudinal conduction coils perpendicular to each other and wound around the shell; the driver transmits the alternate current of multi-step squarewave to the drive coil of the bearing angle sensor to generate circular induction magnetic field; the said magnetic field synthesizes with the geomagnetic field inside the sensor ring to magnetize the magnetic material of the sensor ring; transverse-longitudinal conduction coils respectively produce a electromotive force; transverse-longitudinal signal processor respectively converts the aforesaid electromotive force signals into DC voltage signals directly proportional to the transverse and longitudinal magnetic field components; the transverse-longitudinal analog/digital converter respectively converts the DC voltage signals into digital signals; the microprocessor first filters the noise in the digital signals of the transverse and longitudinal magnetic fields with a filter, then compute the bearing angle following error compensation; the circular error compensation technique goes as follows: after the electric compass is mounted on the object and before it is used the first time, turn the object one round and the microprocessor records the transverse and longitudinal output signals, and finds out the maximum and minimum of each axis so as to compute the scale factor and bias values of the transverse and longitudinal output signals and record these values; when the electrical compass is used thereafter, the transverse and longitudinal output digital signals are normalized by the scale factor and their bias deducted before the bearing angle is calculated.

Title: Pattern recognition employing arbitrary segmentation and compound probabilistic evaluation
Inventor: BOKSER MINDY
IPC: G06F40/00
Filed: 1997-03-19
Granted: 1999-07-21
Abstract: A pattern recognition system classifies images of patterns in which the definition of individual features of the pattern may have become blurred. The images is segmented into pieces of arbitrary size and shape, and various combinations are examined to determine those which represent the most likely segmentation of the pattern into its individual features. These individual features are then classified, according to known techniques. Through the use of a second order Markov model, not all possible combinations of pieces need to be examined, to determine the best ones. Rather, the examination of various combinations is limited in accordance with previously determined information, to thereby render the process more efficient. By combining multiple, independently determined probabilities, the accuracy of the overall operation is enhanced.

Title: Method and apparatus for high efficiency reverse osmosis operation
Inventor: MUKHOPADHYAY DEBASISH
IPC: B01D61/12
Filed: 1997-08-11
Granted: 2000-09-11
Abstract: A process for treatment of water via membrane separation equipment. Hardness and non-hydroxide alkalinity are removed from feedwaters to very low levels, preferably by simultaneous removal in a weak acid cation ion exchange resin. Then, ionization of sparingly ionizable components in the feedwater is substantially accomplished by increasing the pH of the feedwater preferably up to about pH 10.5, or higher. In this manner, species such as silica become highly ionized, and (a) their rejection by the membrane separation process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Passage of weakly ionized species such as boron, silica, and TOC is reduced by a factor of ten or more. Recovery ratio of ninety percent (90%) or higher is achievable with most brackish feedwaters, while simultaneously achieving a substantial reduction in cleaning frequency. The method is particularly useful for the preparation of high purity water. Although the silica level in the reject water in this process is increased from the conventional range of approximately 150 ppm to a level of 450 ppm or better (thus increasing recovery rates), significantly improved levels of silica contamination in the ion-exchanged polished permeate are achieved. New Ultra Pure Water (UPW) systems utilizing this process will have thirty to fifty percent lower capital costs and at least twenty five percent lower operating costs compared to conventional UPW systems.

Title: Semiconductor die attaching apparatus having die pickup tool with plural contact parts for preventing electrostatic discharge
Inventor: JIN HO-TAE
IPC: H01L21/683
Filed: 1998-06-04
Granted: 2000-06-11
Abstract: A die pickup tool for semiconductor devices and a die attaching apparatus having the tool are disclosed. A semiconductor die which will be attached to a lead frame by the apparatus includes a passivation layer partially covering a top surface thereof. Therefore, chip pads and fuses on the top surface are exposed outwardly through the passivation layer, so that electrostatic discharge may occur in manufacture of the device. In order to solve the problem, the pickup tool includes a body and a vacuum line connected to the body. Also, the tool includes a plurality of contact parts, each of which extends outwardly from the body and has a vacuum hole connected to the vacuum line through the inside of the body. The contact parts standing apart from one another correspond to each divided section of the passivation layer. Therefore, the contact parts including the holes are out of contact with the exposed chip pads and fuses when a vacuum from the vacuum line is applied to the die through the hole. Such pluralization and separation of the contact parts make the contact area between the die and the tool limited within the scope of the passivation layer, thereby preventing the electrostatic discharge. Furthermore, die attaching apparatuses which have one or two pickup tool, a mount stage, and a bond stage or a head are also disclosed.

Granted: 2000-08-21
Abstract: To provide a cold-cathode tube lighting circuit which quickly and smoothly carries out lighting of a cold-cathode tube and prevents damage of a piezoelectric transformer as an inverter transformer in the lighting circuit, the lighting circuit is provided with a protection circuit for detecting a primary current of the piezoelectric transformer. The protection circuit stops operation of an oscillator for driving the piezoelectric transformer when the primary current is excessive. The protection circuit may be provided to detect excess of a secondary voltage of the piezoelectric transformer. When the cold-cathode tube is used as a backlight for a liquid crystal display driven by the use of a scanning frequency, a dimmer circuit is used for producing a dimmer signal with a dimmer frequency and a controlled duty ratio given by a manual selector for controlling start and stop of the oscillator according to a desired brightness of the backlight. The dimmer frequency is obtained from frequency division of the scanning frequency. The controlled duty ratio is also modified corresponding to the divided frequency.
