Publication number: 20040239377Abstract: A multi-channel integrated circuit is provided in which each channel has an analog section and a digital section. Each channel of the readout chip employs low noise charge sensitive amplifier at its input followed by other circuitry such as shaper, pole-zero, peak hold, different comparators, buffers and digital control and readout. Each channel produces a self-trigger and a fast timing output. Channel-to-channel time differences are also recorded. Integrated circuit also provides a large dynamic range to facilitate large range of applications. The trigger threshold can be adjusted to provide energy discrimination. The chip has different, externally selectable, operational modes including a sparse readout mode in which only the channels which have received signals greater than a preselected threshold value are read out. The sparse readout mode results in increased data throughput, thus providing fast data acquisition capabilities.Type: ApplicationFiled: February 18, 2004Publication date: December 2, 2004Applicant: NOVA R & D, INC.Inventors: Tumay O.

Patent number: 6825293Abstract: Some properties such as dart impact strength, hexane extractables and resin stickiness of a polyethylene copolymer produced in a gas phase polymerization using a Ziegler-Natta catalyst are better controlled by regulating the ratio of aluminum from the co-catalyst to the polymer production rate. This enables one to improve properties such as dart impact strength and reduce hexane extractables by changing the amount of co-catalyst fed into the reactor.Type: GrantFiled: August 20, 2001Date of Patent: November 30, 2004Assignee: Nova Chemicals (International) S.A.Inventors: Shivendra Kumar Goyal, Timothy Walter Wiwchar, Victoria Ker, Mark Kelly

Patent number: 6815947Abstract: A method and system are presented for measuring in an electrically conductive film of a specific sample including data indicative of a free space response of an RF sensing coil unit to AC voltage applied to the RF sensing coil. The sensing coil is located proximate to the sample at a distance h substantially not exceeding 0.2 r wherein r is the coil radius; an AC voltage in a range from 100 MHz to a few GHz is applied to the sensing coil to cause generation of an eddy current passage through the conductive film; a response of the sensing coil to an effect of the electric current through the conductive film onto a magnetic field of the coil is detected and the measured data indicative of the response is generated. The thickness of the film is determined by utilizing the data indicative of the free space measurements to analyze the measured date. The method thus provides for measuring in conductive films with a sheet resistance Rs in a range from about 0.009 to about 2 Ohm/m2.Type: GrantFiled: June 12, 2003Date of Patent: November 9, 2004Assignee: Nova Measuring Instruments Ltd.Inventors: David Scheiner, Yoav Many, Rahamin Guliamov, Shahar Gov

Patent number: 6806114Abstract: A process for creating a broadly tunable Distributed Bragg Reflector (DBR) with a reduced recombination rate. According to the current invention, this may be achieved by creating electron confinement regions and hole confinement regions in the waveguide of the DBR. Preferably, this is achieved by engineering the band gaps of the DBR waveguide and cladding materials. Preferably, the materials selected for use in the DBR may be lattice matched. Alternately, two or more thin electron confinement regions and two or more thin hole confinement regions may be created to take advantage of strain compensation in thinner layers thereby broadening the choices of materials appropriate for use in creating a broadly tunable DBR. Alternately, graded materials and/or graded interfaces may be created according to alternate processes according to the current invention to provide effective electron and/or hole confinement regions in various DBR designs.Type: GrantFiled: November 7, 2001Date of Patent: October 19, 2004Assignee: Nova Crystals, Inc.Inventor: Yu-Hwa Lo

Patent number: 6806971Abstract: An optical system is presented for use in a measurement system for measuring in patterned structures, which is particularly useful controlling processing of the structure progressing on a production line. The system comprises an illuminator unit producing illuminating light to be directed to the structure to produce returned light, a detector unit comprising an imaging detector and a spectrophotometer detector, and a light directing assembly. The light directing assembly defines first and second optical paths for the light propagation. The optical elements accommodated in the first optical path affect the light to provide a relatively small measuring area of the structure's plane. The second optical path is located outside the first optical path, the light propagation through the second optical path providing a relatively large measuring area, as compared to that of the first optical path.Type: GrantFiled: May 28, 2002Date of Patent: October 19, 2004Assignee: Nova Measuring Instruments Ltd.Inventor: Moshe Finarov
