Abstract: An apparatus installed on a host vehicle derives travel locus/condition information relating each of a plurality of reception positions on the vehicle to a corresponding reception condition (e.g., received signal strength), and updates the information at each of successive positions along a travel locus of the vehicle. The currently obtained information is compared with reference travel locus/condition information previously obtained by travel along a reference travel locus, in the same travel direction, by the host vehicle or similar vehicle. Degrees of similarity between the currently obtained information and the reference information are evaluated, and the results used to detect changes in position of the host vehicle along a direction at right angles to its advancement direction.

Abstract: A radio communication terminal comprises a data classification part, a data value unit price determination part, a transmission value unit price determination part, a transmission order control part, a resource allocation part and a transmission part. The data classification part acquires transmission data from a data supply source, classifies the transmission data by priority class based on a communication quality request, which is determined by types of the transmission data, and stores the transmission data in a priority buffer in correspondence to the priority class. The data value unit price determination part determines a data value unit price of the transmission data. The transmission value unit price determination part determines a transmission data value unit price based on the data value unit price. The transmission order control part assigns a transmission order to the transmission data having the transmission data value unit price higher than a predetermined transmission threshold value. The resource allocation part allocates a communication resource to the transmission data based on the transmission order. The transmission part transmits the transmission data by the communication resource allocated by the resource allocation part.

Abstract: A wireless positioning terminal includes a wireless receiver receiving reception signals from a wireless transmitter via multiple communication links. A multi-link-base reception informational item is determined by evaluating reception signals via the communication links. The multi-link-base reception informational item, which has a value varying with a position of the wireless positioning terminal, varies with the position differently from an informational item of a reception signal via one of the communication links. A base trajectory is stored which represents correspondence relation about points between (i) a position of the wireless positioning terminal and (ii) the multi-link-base reception informational item. A measured trajectory is generated which represents correspondence relation about points between (i) a calculated position variation and (ii) the multi-link-base reception informational item. A current position of the wireless positioning terminal is estimated based on a matching between the base trajectory and the measured trajectory.

Abstract: A message notification system includes a message transmitting apparatus and a message receiving apparatus. In the message transmitting apparatus, transmission data including an acquired message is generated and transmitted. In the message receiving apparatus, the transmission data is received. When the transmission data is received, the message receiving apparatus notifies a receiving-side user of the message in the transmission data. The message transmitting apparatus sets whether nor a receiving-side user is to be re-notified of the message in the transmission data, and sets a re-notification condition for re-notification of the message. When receiving the transmission data with the setting that re-notification is required, the message receiving apparatus stores the message in the transmission data in association with the re-notification condition of the message, determines whether or not the re-notification condition is met, and notifies the receiving-side user of the message which is determined that the re-notification condition is met.

Abstract: A target communication line defined as a congestion determination target and a client that transmits an ACK signal to a communication partner in a case where a signal is received from the communication partner are relayed to each other. It is determined whether a congestion occurs on a target communication line. A communication of the ACK signal is limited by a capture process that captures the signal communicated by the client in a case where determining that the congestion occurs on the target communication line.

Abstract: A terminal apparatus mounted on a movable body is provided to communicate with an external communication apparatus outside the movable body. The terminal apparatus includes an antenna, and a communicator device. The antenna includes a plurality of antenna elements to be arranged along a traveling direction of the movable body. The communicator device is configured to communicate with the external communication apparatus using a communicating antenna element that is at least one of the plurality of antenna elements. The communicating antenna element is selected from the plurality of antenna elements so as to belong to a specified region. The specified region is defined by propagation environment information of an electric wave propagation path of a signal transmitted to and received from the external communication apparatus.
