| 20120005180 | NAVIGATION DEVICE AND METHOD FOR PRESENTING ROAD INFORMATION USING AN ELECTRONIC MAP - A navigation device includes a display screen, a storage unit and a processing unit. The storage unit stores a map database. The map database includes electronic map data, and a plurality of road information each including a road name and a corresponding road speed-limit. The processing unit is operable to access a portion of the electronic map data in the map database, to access the road information corresponding to at least one road of the electronic map data accessed by the processing unit, to render the electronic map data accessed thereby so as to generate an electronic map image in which the at least one road of the electronic map data accessed by the processing unit has a visible indication that corresponds to the road speed-limit of the road information accessed by the processing unit, and to provide the electronic map image to the display screen for display. | 01-05-2012 |
| 20110153195 | Navigation device and alerting method thereof - The present invention discloses a navigation device and the alerting method thereof. The alerting method of the navigation device comprises (a) determining a current location and a destination and displaying corresponding map information; (b) planning possible routes by computing cost of each possible route, selecting the minimum cost route as the optimized route among the possible routes, regarding other possible routes having a relatively higher cost as deviation routes; (c) computing a turning cost for each deviation route, wherein the turning cost represents cost difference between each deviation route and the optimized route respectively in an upcoming intersection, on which the possible routes are branched; (d) at a prompter location issuing a voice guidance about how to follow the optimized route, wherein if the upcoming intersection has a turning cost greater than a warning threshold, then the upcoming intersection is a decision point, and additional alertness is issued before the upcoming intersection. | 06-23-2011 |
| 20100250536 | Method for integrating road names and points of interest in source data - The present invention is directed to a method for integrating road names recorded in a source data, particularly comprising steps of merging all interconnected segments having this road name into a user road group and merging these user road groups if they belongs to the same physical road entity. The present invention also relates to a method for integrating points of interest recorded in a source data, particularly comprising steps of, beginning from node with highest priority in the tree to the other nodes one at a time, finding nodes with same point of interest to redirect all child links of lower priority node to higher priority node among the same point of interest nodes and delete link between the same point of interest nodes; creating geometry relationship based on above new arrangement. | 09-30-2010 |
| 20100010734 | NAVIGATION DEVICE AND METHOD FOR CALCULATING AN ESTIMATED TOTAL TIME REQUIREMENT OF THE NAVIGATION-PLANNED ROUTE - A navigation device and a method for calculating estimated total time requirement of navigation-planned routes with enhanced prediction accuracy includes: a map database for pre-defining calculation parameter and properties of feasible road information and traffic signs along the routes; a configuration module for entering coordinates of indication points determined as a destination where a vehicle reaches; a route planning module for receiving satellite signals of global positioning system, searching the map database for the coordinate of the indication point determined as a departure place and defined by the satellite signals received by a satellite positioning system, and planning simulated routes between the indication point determined as the departure place and the indication point as the destination place; and a process module for calculating traveling time according to properties of the feasible road information of the planned simulated routes and total stopping time according to the calculation parameter and the number of traffic signs along the simulated routes, thus obtaining estimated total time requirement by adding up the traveling time and the total stopping time. | 01-14-2010 |
| 20090259398 | NAVIGATIONAL DIRECTION INDICATING DEVICE - A navigational direction-indicating device includes a Global Positioning System (GPS), a display unit, an activation control unit, a navigation software for generating a direction guidance instruction according to positioning signals received by the GPS, and a plurality of light emitting elements arranged proximate to the display unit. After the navigation software generates the direction guidance instruction, the activation control unit generates activation signals according to the direction guidance instruction and corresponding to the light emitting elements, respectively, so as for a corresponding one of the light emitting elements to emit light, thereby allowing a user to receive the guidance instruction efficiently. | 10-15-2009 |
| 20090256665 | VIBRATION-PROOF HOLDER APPLICABLE TO COMMUNICATION/NAVIGATION DEVICES FOR VEHICLE USE - A vibration-proof holder applicable to a communications/navigation device for vehicle use is provided, characterized by the use of a gap-detecting unit to detect position variations of the communications/navigation device, and an electromagnetic control unit to adjust magnetic intensity of magnetic bodies fixedly installed in the vehicle, wherein first and second magnetic bodies are limited to remain in the same track and to face one another with the same magnetic polar end thereof, such that the communications/navigation device can return to its initial position to achieve the vibration-proof effect. | 10-15-2009 |
| 20090248303 | POWER CONTROL SYSTEM AND METHOD FOR THE SAME - A power control system and method receives and filters a valid GPS signal received by a navigation device and outputs a corresponding performance parameter for the GPS signal, and upon determining that a power management signal is a power-off management signal, determines whether the performance parameter exceeds a predetermined first threshold. If the performance parameter exceeds the predetermined first threshold, a processing module is managed to send a GPS power-on signal that allows power to be provided to a GPS module in the navigation device. Alternatively, if the power management signal is not a power-off management signal, the performance parameter is determined whether it is smaller than a predetermined second threshold value. If the performance parameter is smaller, the processing module is managed to send sends a GPS power-off signal that allows the power provided to the GPS module to be cut off, thereby reducing power consumption of the navigation device. | 10-01-2009 |
| 20090072110 | APPARATUS FOR MOUNTING AN ELECTRONIC DEVICE - An apparatus for mounting an electronic device includes a cantilever rack, amounting seat, and a connecting device. The cantilever rack includes a support arm and a suction member. The mounting seat is adapted for mounting the electronic device. The connecting device includes a spherical pivot member disposed on the support arm, and a rotatable unit. The rotatable unit includes a holder disposed fixedly on the mounting seat, and a controlling member connected removably to the holder. The holder defines an engaging space for receiving the spherical pivot member. The controlling member is operable to switch the connecting device between a loose fitting state and a tight fitting state. | 03-19-2009 |
| 20090009624 | Automatic white balance control system, automatic white balance module, and method thereof - The present invention discloses an automatic white balance control system, an automatic white balance module, and a method thereof. The automatic white balance (AWB) control system calculates a distance value from a coordinate related to the image to a reference point in a color space coordinate system for each image. If the median or mean of the distance values is greater than a threshold value, an automatic white balance operation will be performed. The system dynamically adjusts the threshold value to prevent a blinking caused by the automatic white balance. The white balance module selects an image block of a higher image sharpness to perform a gain adjustment to prevent a monochromatic block from misjudging a white balance gain. | 01-08-2009 |
