    摘要： A fastener for fastening pipes or electrical conduit can be installed with the optional use of nails or screws. The fastener includes sharp teeth or spikes which can be hammered into an external surface, such as wood or masonry. The teeth or spikes are positioned, oriented, and otherwise configured to best suit the intended application. Installation can be accomplished using only the fastener itself and force exceeding a minimal threshold.

    摘要： The invention provides a 2-stroke internal combustion engine comprising two opposed cylinders, each cylinder housing two opposed pistons and having at least one exhaust port and at least one intake port, and a crankshaft having asymmetrically arranged journals and scotch-yoke mechanisms for driving the journals from the pistons. The pistons in each cylinder operate to open its exhaust port or ports before its intake port or ports and to close its exhaust port or ports before its intake port or ports.

    摘要： Embodiments of the present invention include a system and method for implementing a presence system. According to an embodiment of the present invention, responsive to receiving a request for presence information associated with a presentity from a watcher, the presence system receives instructions indicating that an authorization instance other than the presentity shall be given an opportunity to change or verify an authorization rule associated with the request for presence information. As a consequence, the presence system notifies the authorization instance of the request for presence information, thereby enabling the authorization instance to change or verify the authorization rule. The presence system also makes a final decision on the authorization rule on the basis of the instructions and a notification indicating a change or verification of the authorization rule.
