  • Patent number: 8058891
    Abstract: A delay lock loop circuit and its delay amount calibration method is disclosed. An initially set value of a counter is determined by a technique which replaces measurement of a delay amount, whereby a time required for calibration of a delay circuit can be reduced. One counter set value of a plurality of counter set values is loaded, a delay lock loop circuit is switched to a lock mode, and a sequence circuit of a cycle slip detection circuit is reset. Thereafter, a cycle slip detection signal output from the sequence circuit is read, and based on the reading, it is judged whether or not an output signal of a delay circuit causes cycle slip. If the cycle slip is caused, the counter set value is switched. If any cycle slip is not caused, the counter set value is locked, thereby terminating the process.

  • Patent number: 7960996
    Abstract: A variable delay circuit is designed to provided a wider range of delay time to a timing signal. The variable delay circuit includes a variable delay 50 which comprises a DA converter 51 which supplies current 51 based on delay setting data; a delay element 53 which imparts a delay amount Tpd to a prescribed signal and outputs the signal; and a bias circuit 52 which is connected such that the amount of current flown in the DA converter 51 and the amount of current flown in the delay element 53 become equal. The DA converter 51 allows the relationship between the delay setting data DATA and the current Id to be hyperbolic (inversely proportional). As a result, the relationship between the delay setting data DATA and the delay amount Tpd can be linearized, whereby the delay amount obtained by a single stage of the delay element can be increased.

  • Patent number: 7957898
    Abstract: A computational scheme for an INS which utilizes micro-electro mechanical systems (MEMS) sensors resolves issues of unnecessarily large computational burden and numerical instability which happen in using conventional methods using high-end inertial sensors. The first aspect is to omit computing Earth radii of curvatures that were used in a high-frequency application. The second aspect is to ignore the Earth rotation and the rotation of the local tangent plane with respect to Earth which are much smaller than noise and bias in the MEMS sensor output. The last aspect is to assume that the absolute amount of the platform pitch and roll angles is less than 90 degrees. According to the aspects noted above, the computational load will be one-fourth of the conventional method without degradation of accuracy.

  • Patent number: 7945383
    Abstract: A navigation system is able to find an optimum route to a destination even when a large non-digitized area exists between a starting point to the destination. The navigation system produces processing points based on a particular shape and size of the large non-digitized area and determines whether such processing points should be used for route search operations. When it is determined that the route search operation is effective, the navigation system performs A* algorithm search operations with respect to the start point, processing points and the destination and detects an optimum route to detour the large non-digitized area.

  • Patent number: 7925428
    Abstract: A method and apparatus for a navigation system efficiently stores the data associated with a calculated route to the destination in a backup memory by incorporating a direction coding method. The method and apparatus can be advantageously implemented in such a situation where the operation of the navigation system is terminated during the route guidance operation before reaching the destination. Since each direction code requires a small amount of data bit, an overall amount of data for the calculated route can be dramatically reduced and can be stored in a small memory space. When the navigation system is restarted, the calculated route will be reproduced based on the direction codes retrieved from the backup memory, thereby enabling to continue the route guidance operation to guide the user the destination.

  • Patent number: 7925438
    Abstract: A navigation system displays a route guidance list on a monitor screen in an intuitive and organized manner so that a user can easily understand information regarding the maneuvering locations and actions associated with the route to the destination. The route guidance list is structured in a layered manner so that the information regarding the maneuvering actions at the locations closer to the current user position will be prioritized. For example, in the route guidance list, the information regarding the immediate maneuvering location and action is more detailed, enlarged, and highlighted than the others. The navigation system displays the route guidance list in which the information regarding the maneuvering locations and actions will be dynamically changed in response to the changes of the current location of the user.
