Patent number: 7701299Abstract: A low phase noise PLL synthesizer is described in which an initial tuning mechanism uses a conventional divider loop to lock a VCO to a desired output frequency. Once initial lock is achieved, the divider loop is switched out of the circuit in favor of a low phase noise mixer loop. The local oscillator signal for the mixer is derived from the same low phase noise source as the phase comparison frequency.Type: GrantFiled: September 5, 2008Date of Patent: April 20, 2010Assignee: Phase Matrix, Inc.Inventor: Oleksandr Chenakin

Publication number: 20100055149Abstract: A re-rollable membrane for wrapping around and protecting a cylindrical tissue having an injury site. The membrane includes a sheet of a porous matrix formed of cross-linked biopolymeric fibers. In one implementation, the sheet can be spirally rolled so that at least one portion overlaps another portion of the sheet and, upon absorption of a fluid, the overlapping portions adhere to each other closely so as to exclude penetration of cells. In another implementation, the sheet can be helically rolled to form a helix having a pitch of 2 mm to 40 mm and an inner diameter of 1 mm to 50 mm. Also disclosed are methods for making and using such re-rollable membranes.Type: ApplicationFiled: September 3, 2008Publication date: March 4, 2010Applicant: Collagen Matrix, Inc.Inventors: Shu-Tung Li, Debbie Yuen

Publication number: 20090179742Abstract: A tag detecting system for detecting a movement of a person or an object that mounts an RFID tag, a moving object detecting method, and an entrance/exit management system using the moving object detecting system are provided. The tag detecting system detects a specific person or object by restricting a detection area of the RFID tag to a narrow area. Since the moving object detecting method detects a piggyback, the entrance/exit system prevents the piggyback even if there are a number of persons passing through an entrance/exit gate almost at the same time.Type: ApplicationFiled: March 13, 2009Publication date: July 16, 2009Applicants: Hitachi, Ltd., Hitachi Engineering & Services Co., Ltd., MATRIX INC.Inventors: Masahiro Takeshima, Kazuo Tamura, Takeshi Kawahara

Patent number: 7246825Abstract: An erosion-indicating safety fitting having a fluid passage formed within for connection in-line with a pipe and a cage of interconnecting breach passages formed into the block and surrounding the fluid passage, particularly at areas having a predicted risk of erosion. A pressure gauge, connected to the breach passages, registers a change in pressure to equal that of the pressure in the fluid passage should the material between the fluid passage and one or more of the breach passages be eroded by the flow of particulate-laden fluid within the fluid passage. The fitting can then be changed before compromising the safety of personnel and the environment.Type: GrantFiled: September 29, 2004Date of Patent: July 24, 2007Assignee: Worldwide Matrix Inc.Inventor: Marcel Menard
