Patent number: 5987375Abstract: A method and apparatus for selecting a destination in a vehicle navigation system are described. The vehicle navigation system includes a display and a selection control. A first destination is selected from a primary list of destinations in response to a selection signal generated by the selection control. The first destination is placed on a secondary list of destinations in response to its selection. The secondary list includes previously selected destinations from the primary list. For subsequent destination selections, the primary and secondary lists are presented on the display thereby facilitating selection of destinations from both the primary and secondary lists. A feature by which the system may search for a destination across categories is also described.Type: GrantFiled: October 7, 1996Date of Patent: November 16, 1999Assignee: Visteon Technologies, LLCInventor: Haruhisa Tamai

Patent number: 5912635Abstract: Method and apparatus for modifying an odometer reading in a vehicle navigation system to compensate for odometer errors. A first distance measurement is obtained from the odometer, and a second distance measurement is obtained from at least one other sensor. The difference between the first and second distance measurements is determined and an adjustment amount is generated in response thereto. A modification factor is then adjusted by the adjustment amount, the modification factor being for modifying the odometer reading. The odometer reading is then modified with the modification factor. A method and apparatus for selecting a pulse rate setting in a vehicle navigation system to correspond to a pulse rate associated with the odometer are also described. A first distance measurement is obtained from the odometer and a second distance measurement is obtained from at least one other sensor. The difference between the first and second distance measurements is then determined.Type: GrantFiled: December 17, 1997Date of Patent: June 15, 1999Assignee: Visteon Technologies, Inc.Inventors: Hidekazu Oshizawa, Toshikazu Sakakibara

Patent number: 5910177Abstract: A method and apparatus are provided for generating a route from a source location to a destination in a vehicle navigation system. Initially, the system generates a first partial route from the source location to the end of the first partial route. The system then determines whether a second maneuver is within a first distance from a first maneuver at the end of the first partial route. Where the second maneuver is within the first distance, the system increases the cost associated with the second maneuver. The system then generates a second partial route from the end of the first partial route to the destination, generation of the second partial route being based at least in part on the cost associated with the second maneuver.Type: GrantFiled: December 9, 1996Date of Patent: June 8, 1999Assignee: Visteon Technologies, LLCInventor: Gary Zuber

Patent number: 5909153Abstract: A modulator loop designed to operate in a frequency range of interest is described. The loop includes a loop output terminal and a switching stage, the output of which is coupled to the loop output terminal. The switching stage has a first delay associated therewith. The output of a modulator stage is coupled to the input of the switching stage. A first feedback path is coupled between the loop output terminal and the feedback input of the modulator stage. A feedback filter is coupled between the output of the modulator stage and the feedback input of the modulator stage which compensates for the first delay. The feedback filter is operable to transmit frequencies outside the frequency range of interest and attenuate frequencies in the frequency range of interest.Type: GrantFiled: February 5, 1998Date of Patent: June 1, 1999Assignee: Tripath Technology, Inc.Inventors: Cary L. Delano, Adya S. Tripathi

Patent number: 5904728Abstract: A method and apparatus are provided for providing route guidance to a user of a vehicle navigation system. A route is generated which corresponds to a plurality of maneuvers. A warning distance is determined from a particular geographic location associated with a particular maneuver, the warning distance being based in part on a variable parameter. A maneuver instruction corresponding to the particular maneuver is then provided at the warning distance from the particular geographic location. In some embodiments, where the particular maneuver corresponds to a first junction, and a second junction similar to the first junction is within the warning distance, the warning distance is adjusted to an adjusted warning distance.Type: GrantFiled: October 11, 1996Date of Patent: May 18, 1999Assignee: Visteon Technologies, LLCInventors: Haruhisa Tamai, Satish Pai

Patent number: 5902350Abstract: The present invention provides a method and apparatus for generating a maneuver indication for an intersection having a turn-lane connector which is consistent with what a driver sees and expects. According to one aspect of the invention, it provides a method for providing maneuver indications to a driver for an intersection having a turn-lane connector which includes the steps of (a) determining when the intersection includes a turn-lane connector, (b) determining whether it is appropriate to collapse the turn lane into the main portion of the intersection for the purposes of generating a maneuver indication, (c) collapsing the turn lane into the intersection when it is appropriate, (d) generating a maneuver indication for the collapsed intersection, and (e) outputting the maneuver indication to the user in time so that the driver may use the turn-lane connector if desired.Type: GrantFiled: October 30, 1996Date of Patent: May 11, 1999Assignee: Visteon Technologies, LLCInventors: Haruhisa Tamai, Simon Desai

Patent number: 5884097Abstract: A data structure and method are disclosed for transferring object attributes between platforms in a distributed computing environment. The method includes creating an application description file. The application description file includes a type ID and an object name. The type ID references a type information file. The application file includes an attribute data block and the attribute data block contains data for attributes that are included in the object. The attribute description file is transferred to a platform that includes the type information file and the type information file includes a memory offset map that determines a sequence of attribute data storage in the attribute data block. Thus, the object attributes are received by the platform and the type information file provides a memory offset map for individual attributes in the attribute description file.Type: GrantFiled: May 17, 1997Date of Patent: March 16, 1999Assignee: Intertop CorporationInventors: Shih-Gong Li, Yun-Yong Shen, Sing Ban Robert Tien, Tu-Hsin Tsai, Ching-Yun Yang

Patent number: 5801681Abstract: A method and apparatus for generating a control signal which corresponds to movement of an object in contact with a first surface are described. The apparatus includes a platen having the first surface. The platen is characterized by a critical angle beyond which light incident upon the first surface is not transmitted. A source of electromagnetic radiation emits electromagnetic radiation through the platen thereby illuminating the object. A detector having a plurality of sectors receives a portion of the electromagnetic radiation diffused by the object and transmitted through the platen beyond the critical angle. The sectors of the detector accumulate charge in response to the incident electromagnetic radiation. Conversion circuitry then converts the charge accumulated in the detector to the control signal, which in a specific embodiment is for controlling the movement of a pointer on a display.Type: GrantFiled: July 30, 1996Date of Patent: September 1, 1998Inventor: Michel Sayag
