  • Patent number: 11522990
    Abstract: An in-vehicle navigation apparatus with a handsfree function establishes a Bluetooth communication link with a cellular phone. When receiving from the cellular phone outgoing call history data and incoming call history data, which were stored in the cellular phone before establishing the Bluetooth communication link, the in-vehicle navigation apparatus stores, in a work memory, the received outgoing call history data and the received incoming call history data, equally to, of the navigation apparatus itself, outgoing call history data and incoming call history data. An outgoing call operation then becomes possible using outgoing call history data and incoming call history data, which are stored in the work memory.

  • Patent number: 9026045
    Abstract: An in-vehicle apparatus selects, as a profile connection mode, one connection mode out of a first connection mode and a second connection mode, and performs profile connection using the selected one connection mode. The first connection mode is to transmit a profile connection request signal to a communication partner so as to start a connection procedure; the second connection mode is to wait for reception of a profile connection request signal from the communication partner for a predetermined time so as to start the connection procedure. When the profile connection using the selected one connection mode fails, a connection procedure using the other connection mode that was not selected previously is started. When the profile connection using the other connection mode is successful, upon occurrence of a next profile connection request, the other connection mode is selected as a profile connection mode.

  • Patent number: 8849204
    Abstract: A subject short-range wireless communication apparatus capable of simultaneously connecting multiple profiles with another short-range wireless communication apparatus acting as a connection counterpart is disclosed. The subject apparatus comprises: a communication disconnection detection device that, in cases where a first profile is connected between the subject apparatus and the another apparatus, detects whether or not the first profile is disconnected due to the subject apparatus' non-acceptance of a connection request of a second profile sent from the another apparatus; and a communication re-connection device that, in response to disconnection of the first profile detected by the communication disconnection detection device, re-connects the first profile with the another apparatus.

  • Patent number: 8700103
    Abstract: A vehicle terminal apparatus has a connection monitoring unit for monitoring a disconnection of a communication link between a wireless communication device and a portable terminal, considering an abnormal disconnection of the communication link as a link loss, considering a disconnection of the communication link by a disconnection process by the wireless communication device as a first disconnection, and considering a disconnection of the communication link by a disconnection process, by the portable terminal as a second disconnection; and a connection condition determination unit for determining a wireless connection condition of the wireless communication device based on a disconnection reason that accounts for a reason for disconnection and a pre-disconnection call condition that is a call condition of the portable terminal immediately before the disconnection when the disconnection of the communication link is detected by the connection monitoring unit.

  • Patent number: 8660546
    Abstract: An information processing apparatus includes a data storage portion that stores data records in which second data is associated with first data; a communicating portion that communicates with an external device; an updating portion that receives the data records from the external device and updates the data records; a screen controlling portion that displays one or more of the first data or the second data, and that receives a specifying operation specifying the first data; a determining portion that determines whether the information processing apparatus is in a state, in which control that uses the first data will be started in response to the screen controlling portion receiving the specifying operation; and a caching portion that caches the first data specified by the specifying operation separately from the data records stored in the data storage portion, when it is determined that the information processing apparatus is in the state.

  • Publication number: 20140018003
    Abstract: If a cellular phone with which a communication link is established is compliant with PBAP (Phone Book Access Profile), an in-vehicle navigation apparatus with a handsfree function stores and arranges, in a work memory device, phone book data transmitted automatically from the cellular phone. Thus, the newest phone book data can be made available. On the other hand, if the cellular phone is not compliant with PBAP, the in-vehicle navigation apparatus stores and arranges, in the work memory device, phone book data, which are presently stored in a storage memory device. Thus, if the presently stored phone book data, which are not newest, are desirable, they can be made available.

  • Patent number: 8620217
    Abstract: A short range wireless communication apparatus is disclosed. When multiple communication protocols including a first communication protocol and a second communication protocol are simultaneously connected between the short range wireless communication apparatus and another short range wireless communication apparatus, the short range wireless communication apparatus notifies the another short range wireless communication apparatus a second communication protocol connection request if the first communication protocol is disconnected in response to transmission of a first communication protocol disconnection request to the another short range wireless communication apparatus and then the second communication protocol is disconnected in response to transmission of a second communication protocol disconnection request from the another short range wireless communication apparatus.
