Inventor: SHIN HELEN HAEKYUNG
IPC: G06T5/00
Filed: 2001-05-10
Abstract: A method and apparatus for multi-level color error diffusion employs semi- vector quantization. When operating on image data comprising three color separations, the method employs a vector quantization for the two separations with the most visually perceptive color output to generate a multi-level output pixel for each separation based on the sum and a difference of the input pixel values for the two separations. The method generates multilevel output pixels for the third color separation using scalar error diffusion.

Title: Direct digital frequency synthesizer and a hybrid frequency synthesizer combining a direct digital frequency synthesizer and a phase locked loop
Inventor: KHAN NASSERULLAH
IPC: G06F1/03
Filed: 2001-06-01
Abstract: A direct digital frequency synthesizer and a hybrid frequency synthesizer combining the direct digital frequency synthesizer and a phase locked loop is provided. The direct digital frequency synthesizer includes a phase accumulator that is configured to generate a discrete phase signal. Spurious phase modulation in the discrete phase signal is reduced by a noise shaper, and the output of the noise shaper is then used to address a phase-to-amplitude translator. The phase-to-amplitude translator generates a discrete waveform which is converted to a continuous waveform by a digital to analog converter. The hybrid frequency synthesizer uses a mixer to combine a reference frequency generated by a reference source and a DDFS output signal generated by a direct digital frequency synthesizer. The output from the mixer is then coupled to the input of a phase locked loop which multiplies the mixer output to generate the frequency synthesizer output.

IPC: G06F17/30

Abstract: The present invention is directed to an improved mapping system and code generation system. Embodiments of the present invention separate the mapping of data elements into two metalevels. The first metalevel maps between types of elements (e.g., string, int, float, varchar, etc.). This first metalevel mapping is associated with an object that contains a method (i.e., a function) which performs the conversion between the type of the element from a first data structure to the type of element in a second data structure. The second metalevel describes the actual mapping between the data elements at issue. Accordingly, the second metalevel results in an instance of the first metalevel object. Source code or scripts generated in accordance with this separation provide numerous advantages including improved flexibility, reduced storage space usage and others. The two metalevel modeling of the invention can be embodied in source code (or script) generators to generate more efficient source code (or scripts).

Title: A system for providing an integrated circuit with a unique identification
Inventor: LOFSTROM KEITH
IPC: H01L23/544
Filed: 2000-02-11
Abstract: An integrated circuit identification device (ICID) (38) to be incorporated into an integrated circuit (IC) (40) includes an array of electronic cells (46) in which the magnitude of an output signal of each cell is a function of randomly occurring parametric variations which vary from cell-to-cell. The ICID (38) also includes a circuit for measuring (50) the output of each cell and for producing output data having a value reflecting the particular combination of measured characteristics of all of the elements of the array (46). When we make the number of elements in the array (46) large enough, we insure that to a high degree of probability, the pattern of measured array cell characteristics for an ICID (38) embedded in any one IC (40) will be unique and distinguishable from such patterns measured by ICIDs (38) embedded in millions of other ICs (40). Thus the value of the output data produced by an ICID circuit (38) acts as a unique "fingerprint" for the IC  (40) in which it is installed, and can be used as a unique identification (ID) for that IC (40).

Title: Method and apparatus for aligning an optical device
Inventor: SATO AKIMITSU
IPC: G02B6/32
Filed: 2002-02-26
Abstract: A method of aligning a fiber collimator in a short time.      Light emitted from a collimator is reflected by a mirror.      Reflected light passes through the collimator, and is measured by a light intensity measuring device. Rotating bodies rotatably support the mirror about an X-axis and a Y-axis orthogonal to the optical axis. An aligner simultaneously drives the rotating bodies to scan an optimal angle for the mirror. With the mirror fixed at the optimal angle, the distance between a collimation lens of the collimator and the optical fiber is changed. Subsequently, the optimal angle of the mirror is again scanned.
Patent CA-2377800-A1 (CA)
Inventor: LEBRETON GREGORY T O
IPC: F04B49/02
Filed: 2002-03-13
Abstract: This invention is a device used to monitor the prime of chemical feed pumps for a variety of automated feed systems. This device is designed for, though not restricted to, use in chemical feed systems that automatically apply non-flammable chemicals to industrial systems such as boilers, cooling towers, or waster water treatment programs. A  sensor is placed inline with the chemical feed tubing which delivers chemical to the requiring process. This sensor detects the presence of a water based liquid and provides a "green light" signal to system operators when chemical is present within the chemical feed tubing. When the prime is broken within the chemical feed pump, air enters the tubing. Chemical then is no longer being pumped through the chemical feed system and the aforementioned sensor detects an absence of water based liquid. A light and/or audible alarm signals the system operators indicating that the chemical feed system is failing to deliver chemical to the requiring operation and the chemical feed pumps require re-priming.
