Title: A receiver, a frequency synthesis circuit and a charge pump
Inventor: KASPERKOVITZ WOLFDIETRICH G
IPC: H04B1/16
Filed: 1997-04-01
Granted: 1999-07-01
Abstract: A charge pump is proposed for supplying at its output a first current in response to an up-pulse and sinking a second current in response to a down-pulse, which charge pump comprises first means for converting the first control signal into the first current and second means for converting the second control signal into the second current, said first and second means comprising means for filtering the respective control signals. By providing this filtering the demands on the high frequency performance of current mirrors used in the charge pump are greatly reduced as the mirrors do not need to mirror current pulses but only filtered current pulses. This allows the use of relatively slow PNP current mirrors, even at pulse frequencies above the transition frequency of the PNP transistors.

Title: Superheated vapor dryer system
Inventor: CLARK ROBERT H
IPC: B08B3/04
Filed: 1997-08-15
Granted: 2000-12-01
Abstract: In a vapor drying system, solvents such as isopropyl alcohol (IPA) are boiled and condensed to provide a means of removing water and other contamination from process parts loaded into the equipment. The parts enter the apparatus via an automated lift assembly. Upon entering the vapor zone, solvent condenses on the parts and fixtures due to a temperature differential, displacing the contaminants. This condensate/contaminant waste stream gravity drains to a buffer tank below via a sloped, temperature-controlled drip tray. After vapor condensation on the parts ceases, drying is accomplished using superheated vapors formed in a stabilized zone generated by one or more offset boil sumps and separate vapor heat exchangers. Any liquid solvent remaining on the parts is flash-dried in the vapor zone, so that parts emerge clean and dry. The invention incorporates a computer-implemented PLC to control process parameters, cover mechanism, transport mechanism, safety features during operating, idle and standby conditions.

Title: Method and apparatus for determining the rate of received data in a variable rate communication system
Inventor: CHEN TAO
IPC: H04L7/08
Filed: 1997-10-14
Granted: 1999-07-01
Abstract: The apparatus and method are employed in a communications system has a transmitter and a receiver, where the receiver determines at which of several rates individual frames in a signal have been transmitted by the transmitter. For example, if the transmitter employs four transmission rates, the receiver decodes each frame of the received signal based on the four rates to produce four cyclic redundancy check (CRC) bits, four symbol error rate (SER) values and one or more Yamamoto check values. If only two of the CRC bits check, then the receiver compares to each other the SER values for those two rates to determine at which of the two rates a current frame was transmitted. If only one of the CRC bits check for a given rate, then the SER value for that rate is compared with a maximum SER threshold for that rate. Additionally, SER values for the other rates can be compared to minimum SER thresholds. Furthermore, the Yamamoto check values can be analyzed to determined whether looser or tighter minimum and maximum SER thresholds should be employed if the Yamamoto values check for the current rate, or do not check, respectively.

Title: Ordered structures in homogeneous magnetic fluid thin films and method of preparation
Inventor: HORNG HERNG-ER
IPC: H01L49/00
Filed: 1998-03-20
Granted: 2001-05-16
Abstract: Methods for preparing homogeneous magnetic fluid compositions capable of forming ordered one dimensional structures or two dimensional lattices in response to externally applied magnetic fields are disclosed. The compositions are prepared using improved co-precipitation methods in which the steps of the procedure have been tuned to reduce sample heterogeneity. Fe3O4 or MnFe2O4 particles are coated with a surfactant and dispersed in a continuous carrier phase to form these homogeneous magnetic fluid compositions. The ability of these compositions to generate ordered structures can be tested by holding a magnet near a thin film of the compositions and observing the formation of colors in the region near the magnet. Methods for controlling the characteristic spacing of the ordered structures formed by the composition also are disclosed. Relevant parameters include the thickness of the film, the strength and orientation of the externally applied magnetic field, the rate of change of field strength, the volume fraction of the magnetic particles dispersed in the continuous phase, and the temperature of the homogeneous magnetic fluid. The homogeneous magnetic fluid composition is useful for the manufacture of liquid crystal devices. The devices take advantage of the serendipitous fact that the spacings in the material are on the order of the wavelength of visible light. A variety of magnetic-optical devices can be constructed that use the ordered structures to diffract, reflect, and polarize light in a controlled and predictable manner. These devices include color displays, monochromatic light switches, and tunable wavelength filters.
