Publication number: 20040155844Abstract: Several driver circuits for energizing series arrays of LEDs are disclosed. The LED driver circuits incorporate programmable microcontrollers and switching regulators in circuits that permit precise control of current applied to the series array of LEDs. One driver circuit senses the condition of a SYNC line such that the light emission pattern of multiple LED light sources, each with a driver circuit connected to the SYNC line may be coordinated without need for a central controller. Another driver circuit applies an overdrive current to the LEDs for a first pre-determined time period, then ramps down the applied current to a sustainable level. A four channel driver circuit provides each channel with electronic switches arranged to simultaneously turn on and electrically connect a constant current source to an LED array, resulting in abrupt turn on and turn off of the LEDs.Type: ApplicationFiled: February 7, 2003Publication date: August 12, 2004Applicant: Whelen Engineering Company, Inc.Inventor: James L.

Patent number: 6774362Abstract: There is disclosed an analytical method capable of performing an analysis in electron microscopy by directing an electron beam at set analysis points wherein a reference image is displayed on a monitor and a user selects plural analysis points within the image. The specimen stage is returned to the approximate position where the reference image was obtained and a new image is obtained. At this time, the newly obtained image does not completely agree in position with the reference image due to accuracy of movement of the stage. The two images are supplied to a deviation amount calculator, which, in turn, compares the images and finds the amount of deviation of the newly obtained image from the reference image.Type: GrantFiled: September 27, 2002Date of Patent: August 10, 2004Assignees: JEOL Ltd., JEOL Engineering Co., Ltd.Inventors: Masumi Katagami, Miyuki Kaneyama

Patent number: 6775621Abstract: The present invention provides a hybridization detection method capable of quantitatively determining the degree of the hybridization between a sample biopolymer and a probe biopolymer. In the method, the amount of a fluorescently labeled probe immobilized on a substrate as a spot is quantitatively determined by determining the fluorescence emitted from a fluorescent material labeling the probe, and the amount of a fluorescently labeled sample hybridized to the probe is quantitatively determined by determining the fluorescence emitted from the fluorescent material labeling the sample. The difference between the amount of the probe and the amount of the sample is normalized with the amount of the probe. Based on the normalized value, the amount of the sample hybridized to the probe can be determined relative to the amount of the probe spotted on the substrate.Type: GrantFiled: December 13, 1999Date of Patent: August 10, 2004Assignee: Hitachi Software Engineering Co., Ltd.Inventors: Noriko Yurino, Kenji Yamamoto, Toshiaki Ito, Toshimasa Watanabe
