  • Patent number: 9281910
    Abstract: In a radio broadcast receiving apparatus and a broadcast frequency detection method, a frequency fm at which a reception strength (an S meter value) that is equal to or greater than a threshold value Th0 and is greater than reception strengths at frequencies (fm?1) and (fm+1) adjacent to the frequency fm by one step by X or more, is detected as a broadcast reception frequency that is a frequency at which a receivable broadcast is performed. The value of X is set so that it increases with the increase in the reception strength (S meter value) at the frequency fm. As a result, a frequency at which a broadcast is performed can be more accurately detected.

  • Patent number: 9263081
    Abstract: An optical pickup device is one in which a lens holder is held by a movable base by using a resilient wire. A restricting abutting portion is formed at a lower portion of the lens holder. When the lens holder moves excessively downward, the restricting abutting portion comes into contact with a stopper portion to restrict a downward movement of the lens holder, so that it is possible to prevent the lens holder from contacting a unit chassis. When the unit chassis is not mounted on the movable base, it is possible to prevent excessive flexing of the resilient wire caused when an opposing abutting portion of the lens holder comes into contact with the unit chassis.

  • Patent number: 9256779
    Abstract: A gesture recognition apparatus for recognizing a gesture of a predetermined operating body includes a storage unit, having stored therein, correspondence relationships between a plurality of coordinate ranges in relation to the operating body and to a plurality of operation target apparatuses, each of the plurality of coordinate ranges further corresponding to each operation target apparatus of the plurality of operation target apparatuses. An image capturing unit captures one or more images of the operating body, a coordinate detecting detects coordinates of the operating body based on the one or more captured images, and an operation target apparatus specifying unit selects an operation target apparatus corresponding to the detected coordinates of the operating body and the stored correspondence relationships. A gesture recognition processing unit recognizes a gesture associated with the operating body based on one or more captured images and corresponding to the selected operation target apparatus.

  • Patent number: 9214086
    Abstract: A wireless communication device for vehicle-to-vehicle communication includes a vehicle positioning module that uses sensors and detects a current position and a direction of the vehicle. In a map matching, pre-calculated route information and road network information based on the current position are retrieved from map data and a current link of the vehicle is identified and a potential signal pattern is determined regarding a position of next intersection and the road network information based on the current position, the direction of the vehicle and the current link. Based on the potential signal pattern, radio characteristics including a level of intensity, a frequency, and a direction are assigned. A transmitter produces a radio signal of the radio characteristics carrying the current position, the speed and the direction of the vehicle. An antenna module converts the radio signal from the transmitter into radio waves and radiates the radio waves.

  • Patent number: 9180814
    Abstract: A 3D object detecting device includes a driving-lane detecting unit that detects a driving lane of a vehicle; a 3D-object detecting unit that detects, by using pattern recognition technology, a type of 3D object with respect to images captured by side cameras; and a recognition-priority setting unit that varies and sets a recognition priority for the detected type of 3D object, based on the detected driving lane. In accordance with the driving lane of the vehicle, the recognition-priority setting unit sets the priority for pattern recognition lower for a type of 3D object that is less likely to exist in rear left and right sides of the vehicle, to thereby reduce the possibility that a 3D object that should not be regarded as a warning target is erroneously detected from the images as a warning subject.

  • Patent number: 9167395
    Abstract: An information processing system and an electronic message notification method for an information processing system automatically change an incoming account for which an electronic message reception notification is made. An information processing system includes an information terminal provided with a communication function and an in-vehicle device. The information terminal receives an electronic message from the exterior in a corresponding incoming account; configures an incoming account for making a notification of the reception of an electronic message; and when an electronic message has been received by the configured incoming account, notifies the in-vehicle device. The in-vehicle device determines whether or not an electronic message has been distributed to the information terminal from a specific partner; and, if so, changes the configuration of the configuration unit so that a notification that the electronic message has been received from the specific partner is made.

  • Patent number: 9157753
    Abstract: When a narrow-angle branch point PA at which a road branches at a narrow angle gets closer, routes from the narrow-angle branch point to all points a-c reachable by traveling for a distance L after passing of the narrow-angle branch point in a current traveling direction. When the narrow-angle branch point is passed, processing to calculate, as a matching degree of each route, a matching degree between each of the gradients G1-G3 of routes R1-R3, which are indicated by map data, and history Ang of an inclination angle of a vehicle is performed until a route with a matching degree equal to or higher than a predetermined threshold is generated or until a distance L is traveled after the passing of the narrow-angle branch point. When the route with the matching degree equal to or higher than the predetermined threshold is generated, a current position is calculated on the route.

  • Patent number: 9140574
    Abstract: A direction/distance mark is displayed on a map, wherein the direction/distance mark shows a direction line indicating a direction, with a reference point of a map screen being located in a center, a plurality of equidistant circles with the reference point being located in the center, and a distance from the reference point indicated by each equidistant circle. An instructed point on the screen that is touched by a user is detected as a point indicating a direction on the direction/distance mark and a distance from the reference point, and a map including the point is displayed. Accordingly, with one-touch, the currently displayed map can be scrolled to a desired map. Using the same direction/distance mark, it is also possible to display an equidistant range specifying map, a configured range specifying map, and a POI display map.

  • Patent number: 9098928
    Abstract: A vehicle-periphery-image-providing system may include an image-capturing unit, a viewpoint-change unit, an image-composition unit, an object-detection unit, a line-width-setting unit, and a line-selection unit. The image-capturing units, such as cameras, capture images outside a vehicle periphery and generate image-data items. The viewpoint-change unit generates a bird's-eye-view image for each image-data item based on the image-data item so that end portions of the real spaces corresponding to two adjacent bird's-eye-view images overlap each other. The image-composition unit generates a bird's-eye-view-composite image by combining the bird's-eye-view images according to a predetermined layout. The object-detection unit detects an object existing in the real space corresponding to a portion where the bird's-eye-view images of the bird's-eye-composite image are joined to each other. The line-width-setting unit sets the width of the line image corresponding to the joining portion.
