摘要： Systems and methods are provided for a flexible and scalable operating system achieving a fast boot. A computing system is described that includes a reserved static object memory configured to store predefined static threads, and a secure kernel configured to be executed in a fast boot mode. The secure kernel further may be configured to chain the static threads to a secure kernel thread queue stored in a secure kernel work memory, and to create temporary threads in the secure kernel work memory during the fast boot mode. The computing system may include a main kernel configured to be initialized by creating dynamic threads in a main kernel work memory during the fast boot mode. The main kernel may be configured to chain the static threads to a main kernel thread queue, and to assume control of the static threads from the secure kernel.

摘要： A map display apparatus includes a map data memory which stores map data necessary for plotting a map of a predetermined region; a map display which reads map data out of the map data memory and plots a bird's-eye view display by projecting the map data read out from the map data memory onto a projection plane which makes a projection angle with a plane of the map data read out from the map data memory, the projection angle being greater than 0° and less than 90°, the bird's-eye view display including identifying marks which identify items in the bird's-eye view display; and an identifying mark overlap preventer which prevents identifying marks from overlapping one another in the bird's-eye view display.

摘要： In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale. Or, as a further alternative, an input of the projection angle is accepted, and the projection plane is determined on the basis of the projection angle and the position of the view point.

摘要： A keyless entry system employs a pocket-portable radio signal transmitter to be carried by a user and a controller mounted on a vehicle and associated with a vehicle device, such as a door lock mechanism, a trunk lid opener, a window regulator, a steering lock device and so forth, to be operated. Radio signal communication between the transmitter and the controller is performed by electromagnetic induction. According to the present invention, electromagnetic induction is caused between antennas in the transmitter and the controller. In order to provide wide communication area, at least the antenna of the controller serves as a transformer to generate higher loop current for generating sufficiently strong magnetic field therearound.

摘要： A method for detecting an encoded radio signal involves comparing the received signal amplitude with a predetermined threshold amplitude. The difference between the received signal-component amplitude and the noise-component amplitude is derived and used to adjust the threshold amplitude. By adjustng the threshold amplitude depending upon the difference between the signal-component amplitude and the noise-component amplitude, mis-detection which could occur otherwise when the reception amplitude of the noise component is relatively high or the reception amplitude of the signal component is relatively low can be successfully and satisfactorily avoided. In order to implement the foregoing process, an encoded radio signal detecting system comprises detecting means separately detecting the signal-component amplitude and the noise-component amplitude, arithmetic means for deriving the difference between the received signal-component amplitude and the noise-component amplitude and deriving a value proportional to the derived difference, which derived value serves as a threshold amplitude, and comparator means for comparing the received signal amplitude with the threshold amplitude, thereby detecting the presence or absence of encoded radio signals.
