Abstract: An engine with expansion piston located on the end of a motion arm connected to the engine shaft. On the shaft, rotating compression pistons are mounted.  The distance between the two piston types allows for the production of great torque. The geometry of expansion chamber and compression chamber is concentric toroidal. A pressure chamber stores the air-fuel mixture coming from the compression chamber to the expansion chamber and is therefore interposed between the two. The timing of the two or more sliding ports attached to the compression chambers determines the compression volume, while the valves control the communication of the pressure chamber with the other chambers.

Abstract: Methods and apparatus for use by a mobile communication device in switching operation for communications from a wireless wide area network (WWAN) to a wireless local area network (WLAN) are disclosed. While providing operation for communications in the WWAN, the mobile device continually maintains visited-cell site history information, in its memory, indicative of one or more visited cell sites of the WWAN that served the mobile device over a moving time period, and continually monitors the site history information to identify whether it has been contained within a local geographic region over the moving time period. If it has, it is permitted to operate for communications with the WLAN. In response to such permission, the mobile device may enable its WLAN radio transceiver and select the WLAN for communications. The WLAN radio transceiver is, thus, enabled only when needed, which reduces power consumption and saves battery life in mobile device.
