A protocol, method, and apparatus for managing network communications which are particularly well suited for ATM communications across a wireless medium. Contiguous time slots within a frame are allocated to each node having traffic to send. Each node is assured a nominal bandwidth, and excess bandwidth is distributed by demand. The allocation of excess bandwidth can be dependent upon the size of the buffer at each node, as well as the time-criticality of each message. Nodes communicate their requests for allocation by appending such control information to the first of their transmitted packets. The allocation, of each node's transmit and receive time slots, is transmitted to all the nodes at the beginning of each frame. Thereafter, each node need not participate on the network until their allocated time periods, thereby allowing portable devices to enter inactive states to conserve power. The network is operated in a connection mode; connections are established in a relatively non-interfering manner by the use of periodically occurring beacons. Inactive, unconnected, nodes need only monitor the network during these beacon periods, further allowing for power conservation.

A method for manufacturing a memory device, and a resulting device, is described using silicon oxide doped chalcogenide material. A first electrode having a contact surface; a body of phase change memory material in a polycrystalline state including a portion in contact with the contact surface of the first electrode, and a second electrode in contact with the body of phase change material are formed. The process includes melting and cooling the phase change memory material one or more times within an active region in the body of phase change material without disturbing the polycrystalline state outside the active region. A mesh of silicon oxide in the active region with at least one domain of chalcogenide material results. Also, the grain size of the phase change material in the polycrystalline state outside the active region is small, resulting in a more uniform structure.

The present invention concerns a crown for a timepiece comprising a disconnecting gear device for preventing damage to the components of the movement of the timepiece in which it is implemented. For this purpose, the crown is provided with a housing which houses a pipe, to which one end of a winding stem is connected, carrying at least one spring and a rigid ring secured to the crown and comprising notches adapted to cooperate with the spring. In common use, a rotation of the crown causes a rotation of the pipe and thus of the winding stem, via the rigid ring and the spring. Owing to the device according to the present invention, when the mechanical resistance to the rotation opposed by the winding stem, via the pipe, exceeds a predefined threshold, the spring is deformed and is no longer driven in rotation by the rigid ring. Consequently, the winding stem is no longer driven in rotation in such conditions.
