Patent KR-20080076973-A (KR)
Title: Wireless communication method and wireless communication system
Inventor: DOI HIROSHI
IPC: H04L12/28
Filed: 2005-08-01
Abstract: A beacon slot position control part (205) of a wireless communication apparatus constituting a wireless network system determines whether there exists any unused beacon slot in a beacon period. If any unused beacon slot exists before the period in which to transmit the local beacon, then a mobile counter (206) starts to count predetermined super-frames. At a completion of the counting, the local beacon is transmitted by use of the foregoing unused beacon slot. In this way, since the unused beacon slot is now used, the wireless communication apparatus can exhibit an excellent communication efficiency and perform a wireless communication where wasteful power consumption is reduced, even when the number of wireless communication apparatuses entering the wireless network system dynamically varies.

Title: Method of making hernia patch and resulting product
Inventor: BROWN RODERICK B
IPC: A61F2/08
Filed: 2007-02-21
Abstract: A hernia patch comprising a frame made of a plurality of strands made from a shape memory alloy wound together as a cable and a prosthetic mesh material attached to the cable frame. The cable frame forms a loop of a predetermined shape when unconstrained. The cable frame cam is rolled or folded into a tight cylindrical shape and inserted into a small diameter trocar. When the hernia patch is ejected out of the trocar into the patient's abdominal cavity, the frame warms to the point where the alloy is in its austenite form so that it springs to a functional, predetermined configuration. Alternatively, the superelastic properties of the alloy cause the frame to return to the predetermined configuration. The frame is integral with the prosthetic mesh material so that it will not migrate and therefore will not need to be sutured or stapled in place.
