  • Patent number: 7554961
    Abstract: After a first wireless terminal device transitions to a Direct Link Protocol mode, the terminal device transmits an ICMP_echo_request signal directly to a second wireless terminal device and, upon receiving an ICMP_echo_reply signal from the second wireless terminal device within a fixed period of time, counts up the number of times there is a reply. If the ICMP_echo_reply signal is not received within a fixed period of time, then the first wireless terminal device counts up the number of non-replies. As a result, the first wireless terminal device can readily judge whether it is capable of communicating directly with the second wireless terminal device in the Direct Link Protocol mode.

  • Patent number: 7551841
    Abstract: The present invention provides a video camera which ensures that the user will recognize recording mode, thereby preventing the user from confusing a target recording medium. For that, the video camera 100 has a character information composition unit 3 which composites image data outputted by a signal processing unit 2 with predetermined information consisting of characters or pictographic characters to be recognized by the user during operation and outputs a resulting video signal, a liquid crystal monitor 4 which displays the video signal outputted by the character information composition unit 3, a magnetic tape recording unit 8, and a memory card recording unit 9. The predetermined information is target media information which indicates whether the image data outputted by the electronic camera unit 1 is to be recorded on the magnetic tape recording unit 8 or memory card recording unit 9. Immediately after start of recording, a system control unit 5 displays an animated icon which appears to rotate.
