Patent No. 7,554,961 Issued on June 30, Assigned to Canon Kabushiki Kaisha for Wireless Terminal Device (Japanese Inventor)

ALEXANDRIA, Va., July 7 -- Hidetada Nago, Kawasaki, Japan, has developed a wireless terminal device. The inventor was issued U.S. Patent No. 7,554,961 on June 30.

The patent has been assigned to Canon Kabushiki Kaisha, Tokyo.

According to the abstract released by the U.S. Patent & Trademark Office: "After a first wireless terminal device transitions to a Direct Link Protocol mode, the terminal device transmits an internet control message protocol (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."
