Abstract: Disclosed is a chain saw which includes chain saw chain tensioning and braking systems. Tensioning and braking are effected by the presence and control of longitudinal slits in an elongated support which provides a continuous chain channel guide in its outer circumference.

Abstract: In existing standards for packet data communication over enhanced cellular networks, for a subscriber having a static address, the network relies on the terminal to provide the static address. Consequently, the terminal needs to know (be programmed with) its own static address and typically the address of a home agent element of the network. To eliminate the attendant need to provision such address data in the mobile station, the static address is stored in a node of the network, and the network assigns that one address to the mobile station, every time when the subscriber requests packet data service, for example, using a mobile IP (MIP) type address assignment procedure. The address assignment operation may also provide the home agent address to the station.

Abstract: Improved billing accuracy in session-based communications is provided by separating session (or connection) billing from session processing. If two sessions (440, 442) on the same serving node are bridged, so the true stop time of the prior session (440) is not known, the stop time of the prior session is defined as a function of the last activity during (TALS1) that session. To accomplish this, the serving node detects and stores the time of last activity and the time of initiation for each connection and determines the billing time accordingly, regardless of the state of the inactivity timer (430) or whether sessions were bridged by the serving node.

Abstract: A chain saw which includes chain tensioning and braking systems. Tensioning and braking are caused by the presence and control of longitudinal and lateral slits in an elongated support which provides a continuous chain channel guide in its outer circumference.

Abstract: The inventive method is advantageously used in the manufacture of an article that comprises an opto-electronic device (e.g., LED or photodetector diode) that has a substantially planar radiation-emitting or receiving (first) surface region. The method comprises preliminarily positioning the end of a length of optical fiber relative to the first surface region, and causing radiation from a radiation source to be emitted from the fiber end so as to be incident substantially normally on the first surface region. A part of the radiation is reflected, collected by the fiber end, and transmitted to a power meter. The output of the power meter (or a quantity derived therefrom) is compared to a pre-determined measurement value and, if indicated by the comparison, the position of the fiber end is adjusted. A significant aspect of the invention is the existence of an easily measured relationship between the reflected power received by the power meter and the distance .DELTA.
