Patent number: 6870489Abstract: A reusable mechanical fastening means for a vehicle monitoring system facilitates maintenance and repair of the system. A plurality of carrier sections are connected together by clips. The clips have release tabs to move prongs against a spring force, thereby making the clips manually detachable. Vehicle sensing probes have interference ridges which mate with probe openings in the carrier sections. The carrier sections have open bottoms, and the worker can overcome the locking force of the interference ridge by turning the carrier section over and pressing on the probe through the open bottom. The clips can be attached on multiple planes relative to the carrier sections, minimizing torsional play within the extended support train. The clips and carrier sections are also easily manufacturable.Type: GrantFiled: February 28, 2003Date of Patent: March 22, 2005Assignee: 3M Innovative Properties CompanyInventor: Eric R. Cybulski

Patent number: 6844814Abstract: Wireless sensor platforms (10), when deployed, can ascertain whether they can meaningfully participate in communications with more than one cluster (22, 23) of such devices. When true, such multi-cluster platforms can serve as bridge nodes to facilitate the passing of data collected from one cluster to or through another cluster. In a preferred embodiment, the platforms serving as bridge modes (24 and 25) utilize a communication schedule that imposes no greater work load than the load the platform would otherwise have served as an ordinary node, and preferably the workload is considerably reduced. This aids in ensuring that the portable power reserves of the bridge nodes will support bridge operations for at least as long as the clusters are otherwise functioning.Type: GrantFiled: November 12, 2002Date of Patent: January 18, 2005Assignee: Motorola, Inc.Inventors: Kwan Wu Chin, Raad Raad

Patent number: 6661698Abstract: The present invention generally relates to nonvolatile ferroelectric memory control devices, and more specifically, to a nonvolatile ferroelectric memory control device suitable for an embedded memory. In the nonvolatile ferroelectric memory control device of the present invention, a column address area is arranged in the least significant bit region. When a column address is accessed in the same row address, an address transition detecting signal is not generated. According to the present invention, an internal data register array is arranged and a repeated access address controls the data register array so that data stored in the register may be immediately outputted. Accordingly, the nonvolatile ferroelectric memory control device of the present invention can reduce power consumption when the FRAM is used as a program memory in a SOC (System on Chip) structure and extends life of FRAM by decreasing power stress applied to cells.Type: GrantFiled: December 30, 2002Date of Patent: December 9, 2003Assignee: Hynix Semiconductor Inc.Inventor: Hee Bok Kang

Patent number: 6654683Abstract: In an Interactive Real-Time Distributed Navigation system a method and system is disclosed for implementing a warm start/cold start option. Through selection of the warm start option, an interactive session for providing navigational directions to a user is more quickly established because a user's position is assumed not to be ambiguous. A method of the invention verifies this assumption. Through selection of the cold start option, the method of the invention seeks to remove ambiguity in a user's position before providing navigational directions. If, however, a user's position is not ambiguous, the method of the invention reverts to a warm start condition to immediately transmit navigational directions to the user.Type: GrantFiled: June 18, 2001Date of Patent: November 25, 2003Inventors: HaiPing Jin, Yi-Chung Chao, Longxue Li, Ruslan Adikovich Meshenberg, Kentaro Tokusei, Salman Dhanani

Patent number: 6646934Abstract: In the conventional column-side block redundancy for DRAM, competition for the replacing regions occurs unless a repair address of a large number of bits is stored in order to replace with a small replacement unit. According to one aspect of the invention, replacement decision is performed in order that a second replacement region can be made smaller than a first replacement and that the second replacement is given priority over the first replacement. Therefore, the first replacement can be controlled by a repair address of a small number of bits, thus making it possible to achieve a semiconductor device having a defect repair circuit with small area and high repair efficiency.Type: GrantFiled: December 20, 2002Date of Patent: November 11, 2003Assignee: Hitachi, Ltd.Inventor: Takeshi Sakata

Patent number: 6633811Abstract: The method for displaying speed variables in a motor vehicle includes automatically selecting and displaying one of a number of different possible speed scales on a speedometer according to the physical units for speed values employed at the current location of the vehicle. An acoustic and/or optical alarm signal is produced when the vehicle passes from one governmental region in which one set of physical units is used to another in which a different set is used. In addition, speed limits at the current location may be displayed on the speed scale itself by highlighting an appropriate scale mark or producing a scale mark of a different length or color. The current location may be obtained from an on-board GPS. The speed limits and physical units for speed values at the current location are retrieved from a data storage media according to that location. The speed limits may be updated by radio connection. Digital display devices for speed values with similar features are disclosed.Type: GrantFiled: October 19, 2000Date of Patent: October 14, 2003Assignee: Robert Bosch GmbHInventor: Richard Aumayer

Patent number: 6609064Abstract: A system provides the ability to collect and analyze data generated by a global positioning system to assist in monitoring and supervising a user of a vehicle. The system includes a GPS unit incorporated into a vehicle for periodically generating and recording information with regard to the position and velocity of the vehicle. The recorded information is periodically transferred to a remotely located computer via a wireless communications system, within which a grouping program is implemented. The grouping program is used to identify periods where the vehicle is in a stationary mode and periods where the vehicle is in a moving mode traveling from one location to another, based on the information provided by the GPS unit. The system generates a summary in map or report format. The results of the grouping program may be presented on map images representing the area within which the vehicle traveled. Symbols are drawn onto the map images corresponding to the locations of the stationary segments.Type: GrantFiled: August 31, 1999Date of Patent: August 19, 2003Assignee: Qwest Communications Int'l, Inc.Inventor: Vincil C.
