Patent number: 8545396Abstract: A system and method for wirelessly transmitting a video image signal from an endoscopic camera to a receiver or control unit for storage and/or display on a video monitor. Use of a frame-specific, variable compression algorithm capable of progressively encoding a data stream provides for a better performing and higher quality wireless endoscopic camera system capable of generating images at varying resolutions. Use of a short-range, high-performance wireless technology, such as Ultrawideband (UWB), improves the performance capabilities of the system, while minimizing power consumption and extending battery life. Implementations of error correcting codes, as well as the use of multiple transmitting and receiving antennas, further improve the fidelity of the wireless communication.Type: GrantFiled: November 15, 2007Date of Patent: October 1, 2013Assignee: Stryker CorporationInventors: Reid Cover, Emmet McCarthy, Vasudev Nambakam

Patent number: 8372001Abstract: The present invention is directed to reliably prevent a trouble that a battery is loaded either in a state where a ribbon is entirely housed in a battery housing or without a ribbon by a simple method using a ribbon. Guide parts (83, 84) are provided on both side walls (57, 58) of a battery housing (53). A ribbon (81) is set so as to cross the battery housing (53) in a stretched state by the guide parts (83, 84) in a position where the battery can be taken out by drawing the ribbon (81). With the configuration, at the time of loading a battery, by making the ribbon (81) extend outside, the ribbon (81) is not entirely housed in the battery housing (53) or absence of the ribbon (81) in the battery housing (53) can be prevented. By making the battery front end face come into contact with the stretched ribbon (81) and inserting a battery, a normal loading state in which the ribbon (81) is pushed to the deepest place can be assured. The battery ejecting function with a simple ribbon (81) can be reliably displayed.Type: GrantFiled: January 20, 2006Date of Patent: February 12, 2013Assignee: Olympus Medical Systems Corp.Inventor: Toshimasa Akagi
