200946870 IX. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a navigation device, a method for use by the navigation device, and a system including a plurality of navigation devices. Illustrative embodiments of the present invention relate to portable navigation devices (so-called PNDs), and more particularly, include global positioning system (GPS) signal reception and processing functionality. More generally, other embodiments are directed to any type of processing device configured to execute navigation software to provide route planning functionality and preferably also provide navigation functionality. [Prior Art] A portable navigation device (PND) including GPS (Global Positioning System) signal receiving and processing functionality is well known and widely used as an in-vehicle or other vehicle navigation system. In general, modern PNDs include a processor, memory (at least one of volatile and non-volatile memory, and usually both) and map data stored in the memory. The processor cooperates with the memory to provide an execution environment in which a software operating system can be established and, in addition, often provides - or more - soft (four) money pND money can be controlled and provides various other functions. Generally, the steps of the device include allowing the user to interact with the device and controlling one or more input interfaces and one or more output interfaces of the device, and the information can be distributed by the one or more output interfaces. Illustrative examples of the interface include a visual display and a speaker for voice turn-off. Illustrative examples of input interfaces include one or more of the on/off 131162.doc 200946870 operations or other features used to control the device (if the device is built into the vehicle, the buttons may not be In the device, the β1 is on the head, and the 疋 can be on the steering wheel) and the slapstick used to detect the user's words. In a particularly preferred configuration, the output interface display can be configured as a touch-sensitive display (by touch-sensitive overlay or other) to additionally provide an input interface through which the user can operate by touch The device. This type of device will also be used as a sentence; ^ will include / or multiple physical connector interfaces, by means of the entity or the remote __ _

The splicer interface transmits power and conditional data signals to the device and receives power and conditional data signals from the sputum, +^ via the device; and, as the case may be, or a wireless transmitter ^, which allows communication over cellular telecommunications and other signal and data networks (eg, wi_Fi, Μ_Μ & GSM and similar networks). This type of PND device also includes a Gps antenna through which satellite broadcast signals including location data can be received and subsequently processed to determine the current location of the device. The PND device may also include an electronic gyroscope (gyr〇s(3)pe) and an accelerometer that generate the 彳§ number, which may be processed to determine the current angular and linear acceleration 'and' and combined with positional information derived from the GPS signal. Determining the speed and relative displacement of the device and thus the vehicle in which the device is mounted is generally 'these features are most commonly provided in the navigation system within the vehicle, but may also be provided in the PND device (if this is advantageous) ). The utility of such PNDs is primarily manifested in their ability to determine the route between the first location (typically, the departure or current location) and the second location (usually the destination). Such locations may be entered by the user of the device by a wide variety of different parties, 131162.doc 200946870, for example, by postal code, street name and house number, 弁益纱+) Nowhere else to store "Familiar" destinations (such as famous locations, municipal locations (such as stadiums or swimming pools) or other points of interest) and favorite destinations or destinations that have recently been visited. - Usually 'na (4) purely according to the map (four) to calculate the "best" or the best, the route software between the starting address, i and the destination address = best. or " Preferably, the route is determined based on predetermined criteria and the choice of the route along which the driver is guided by the θ n & or the most & route can be very complex and the selected route can take into account existing, predicted and Traffic and road information received dynamically and / or wirelessly, historical information about road speed and driver's own preferences for determining factors in road alternatives. (10) If the driver can specify a route, it should not include a car or a road. In addition, the device continuously monitors road and traffic conditions and provides or elects to change routes due to changing conditions on which the remaining travels will be made. An instant traffic monitoring system based on various technologies (e.g., mobile phone data exchange, stationary phase machine, GPS fleet tracking) is being used to identify traffic delays and feed information into the notification system. • This type of PND can normally be mounted on the instrument panel or sowing glass of the vehicle's but can also be formed as part or in fact of the carrier's onboard computer. Formed as part of the vehicle's own control system. The navigation device can also be part of a portable system, such as a PDA (portable digital assistant), a media player 2 mobile phone or the like, and in this case, the portable system: the functionality of the device is installed by software It is extended on the device to perform route calculations and navigation along the calculated route. 131162.doc 200946870 ❺

Route planning and navigation functionality can also be provided by desktop or mobile computing resources that operate on appropriate software. For example, the Royal Automobile Club (rac) provides online route planning and navigation facilities at http://www.rac.co.uk, which allows users to enter the starting point and destination, so the user's pCm is connected to The server calculates the route (which can be specified by the user), generates a map, and generates a detailed set of navigation commands for directing the user from the selected starting point to the selected destination. The facility also provides pseudo-three-dimensional rendering and route preview functionality for the calculated route, the route preview functionally simulating the user traveling along the route, and thereby providing the user with a preview of the calculated route . In the PND environment, once the route is calculated, the user interacts with the navigation device to select the desired route from the list of suggested routes as appropriate. Depending on the situation, the user may intervene or direct the route selection process, such as by specifying certain routes, roads, locations, or criteria to be avoided for a particular journey. The route calculation aspect of the PND forms a major function, and navigation along this route is another major function. During the navigation along the calculated route, these pNDs often provide visual and/or voice commands for directing the user along the route to the end of the route, i.e., the desired destination. It is useful to follow the route of a selection to the end of the route (i.e., the desired destination). The PND also often displays map information on the screen during navigation, which is updated on the screen, so that the displayed map information represents the current location of the device and thus represents the current revenge of the user or user's vehicle. Set (if the device is being used for navigation within the vehicle). 131162.doc 200946870 The icon displayed on the screen is usually the current device location and is centered, and map information and other map features of the current and surrounding roads near the current device location are also being displayed. In addition, depending on the situation, the navigation information may be displayed in the status bar above or on one side of the displayed map information. Examples of the navigation information include the current road to be deviated from the user's need to select, the nature of the deviation. This property may be represented by a further graphical representation indicating a particular type of deviation (eg 'left turn or right turn'). guide

The navigation function also determines the content, duration, and timing of the voice commands that can be used to guide the user along the route. As you can see, simple instructions such as "(10) turn left and turn" require a lot of processing and analysis. As previously mentioned, the user's interaction with the device can be initiated by a touch screen, or otherwise by a steering column mounted remote control, by sound, or by any other suitable method. Another important function provided by the device is automatic route recalculation in the following cases: the user deviates from the previously calculated route during navigation (accidentally or intentionally); the immediate traffic condition indicates that the alternative route will be more advantageous and the device These conditions can be automatically recognized appropriately, or if the user actively causes the device to perform route recalculation for any reason. It is also known to allow the calculation of routes by user-defined criteria; for example, the user may prefer a scenic route calculated by the device, or may wish to avoid any roads that may occur, are expected to occur, or are currently occurring. The device software will then calculate the various routes and prefer the route along its route including the highest number of points of interest (known as p(1)), which are marked as (10) such as having a beautiful view' or using the indicator shirt on the road. 131162.doc 200946870 The stored information of the traffic conditions of the birth 'sort the calculated routes according to the possible blockage or the delay caused by the blockage. Other route calculations and navigation standards based on ρ〇ι and traffic information are also possible. ❹

Although the route calculation and navigation functions are important for the overall utility of the PND, it is possible to use the device purely for information display or, free-driving ", which only displays the map related to the current I-position's and has not yet The route is calculated and the device is currently not performing navigation. This operation is often applicable when the user is aware of the route along which the trip is to travel and does not require navigation assistance. Devices of the type described above (e.g., Model 720T manufactured and supplied by T〇mT〇m Internati〇nal®) provide a reliable means of enabling a user to navigate from one location to another. However, the theft or loss of such PNDs has become an added problem. Since the PND is small and easy to remove from the carrier, the loss or theft of the PND is common. One of the embodiments of the present invention is directed to at least alleviating one or more of the problems of the prior art. SUMMARY OF THE INVENTION To achieve this goal, a preferred embodiment of the present invention provides a navigation device (200) including a communication unit (270) for communicating with a server (3〇2). The communication unit (270) receives a signal from the server (3〇2) indicating that the navigation device (200) has been lost or stolen and outputs the nickname to the processor (210), the processor (2) 10) configured to affect subsequent actions of the navigation device in response to signals received from the communication unit (270). 131162.doc •10- 200946870 In order to achieve this goal in a step-by-step manner, one of the presently preferred embodiments provides a method for use in a navigation device (200), the method comprising the steps of: self-feeding The device (3〇2) receives a notification indicating that the navigation device (2〇〇) has been lost or stolen; and affects the subsequent behavior of the navigation device (2〇0) in response to the notification. In order to achieve this goal further, the presently preferred embodiment provides a system comprising: a plurality of navigation devices (200); a server (302) ' communicatively coupled to the plurality of a navigation device; the system is characterized in that the server (3〇2) is configured to transmit a signal indicating that the navigation device (200) has been lost or stolen to the navigation device (2〇〇) In the selection, the selected navigation device (2〇〇) is configured to respond to an indication that the navigation device has been lost or stolen. The advantages of these embodiments are set forth below, and other details and features of each of these embodiments are defined in the accompanying separate items and elsewhere in the following embodiments. [Embodiment] A preferred embodiment of the present invention will now be described with specific reference to a PND. However, it should be borne in mind that the teachings of the present invention are not limited to pND, but in fact, the teachings of the present invention are generally applicable to any type of processing device configured to execute navigation software to provide route planning and navigation functionality. Therefore, it can be seen that 'in the context of the present application, the navigation device is intended to include, but is not limited to, any type of route planning and navigation device, regardless of whether the device is embodied as a PND, a navigation device built into the vehicle. It is actually embodied in the computing resources of the route planning and navigation software (such as desktop or portable type 131162.doc • 11 · 200946870 human computer (PC), mobile phone or portable digital assistant (pda)). It will also be apparent from the following that the teachings of the present invention are effective even when the user does not seek guidance on how to navigate from one point to another and only desires to have views and/or information about a given location. In such cases, the "destination" location selected by the user does not necessarily have a corresponding departure location. The user wishes to start navigation from the departure location, and therefore, should not be considered in this article, destination &quot The location or actual reference to the "destination" view means that the route is necessary, the travel to the "destination" must occur, or indeed the presence of the destination requires a corresponding departure Location indication. With the above conditions in mind, the figure illustrates an example view of a Global Positioning System (GPS) that can be used by a navigation device. These systems are known and used for a variety of purposes. In general, GPS is a satellite radio based navigation system that is capable of determining continuous position, speed, time and, in some cases, direction information for an unlimited number of users. The Gps 先前 previously known as navstar incorporates a plurality of satellites orbiting the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can transmit their position to any number of receiving units. • Implement a GPS system when the device is specially equipped to receive (4) data and start scanning for RF signals for GPS signals. After receiving a radio signal from a GPS satellite, the device determines the exact location of the satellite via one of a plurality of different conventional methods. In most cases, the device will continue to scan the signal until it has been transmitted by at least two different satellite signals (note that 'usually not only can use other triangulation techniques The position is determined by only two l31162.doc 12 200946870 signals). After performing a geometric triangulation, the receiver uses three known locations to determine its own two-dimensional position relative to the satellite. This determination can be made in a known manner. In addition, obtaining the fourth satellite signal will allow the receiving device to calculate its three-dimensional position in a known manner by the same geometric calculation. Location and speed data can be continuously updated in real time by an unlimited number of users. As shown in Figure 1, the GPS system is generally indicated by the reference numeral 1〇〇. A plurality of satellites 120 are in orbit around the earth 124. The track of each satellite is not necessarily synchronized with the orbits of other satellites 120, and is in fact likely to be different. The GPS receiver 14 is shown to receive spread-spectrum GPS satellite signals from various satellites 12〇. The spread spectrum satellite signal ι6〇 continuously transmitted from each satellite 120 utilizes a highly accurate frequency standard achieved by an extremely accurate atomic clock. Each satellite 120 transmits a data stream indicative of its particular satellite 120 as part of its data signal transmission. Those skilled in the relevant art will appreciate that the GPS receiver device 140 typically obtains a spread spectrum & 1 > 8 satellite signal 16 自 from at least three satellites 12 〇 for the GPS receiver device 140 to calculate its two dimensions by triangulation. position. The acquisition of an additional signal, which causes a signal 160 from a total of four satellites 12, permits the GPS receiver device 140 to calculate its three dimensional position in a known manner. 2 is an illustrative representation of an electronic component of a navigation device 200 in accordance with a preferred embodiment of the present invention in a block component format.
