    摘要: An apparatus and method to implement a hybrid contention and polling protocol for a communications or computer network is disclosed. Various apparatus and method embodiments of the invention employ specific polls from a primary station for polling identified secondary stations of the network which may be in an active state, general polls to any of a plurality of secondary stations of the network which may be in an unresponsive state to initiate contention access to the network, and general polls for collision resolution in the event that a plurality of secondary stations may simultaneously contend for network access. Various embodiments may also include frequency channel allocation for transmission and reception of data and other information within the network. The various procedures and apparatus disclosed may also be used to apply various polling parameters to optimize network performance.

    摘要: A control station (8) is coupled to a plurality of tributary devices (20, 16, 18) by way of at least one high speed broadcast downstream data channel and more than one shared lower speed upstream data channels. The control station (8) broadcasts data to all the tributary devices (20, 16, 18) and selects a channel for a specific tributary device (20, 16, 18) to respond to a poll. After polling, the tributary device (20, 16, 18) changes the tributary device transmitter (42) to the frequency of the selected channel. The tributary device (20, 16, 18) either sends data to send to the control station (8) or sends a negative acknowledge to the control station (8). If a negative acknowledgment was transmitted, the control station (8) notifies the control station transmitter that the channel is idle.

    摘要: Apparatus and method for measuring ophthalmic formulation retention on the surface of an eye include dissolving a fluorescent macromolecule in an ophthalmic formulation to form a fluorescently labelled formulation; topically administering the fluorescently labelled formulation to an eye, said fluorescently labelled formulation forming a thin film on the eye surface. Apparatus is provided for illuminating the eye to cause fluorescence of the fluorescently labelled formulation as the fluorescently labelled formulation thin film is eliminated from the eye by normal blinking and lacrimation; and for measuring fluorescence from the thin film as a function of time.

    摘要: Frequency spectrum management provides for dynamic spectrum usage adjustment among applications on a shared medium. Dynamic resource management methods are applied to the problem of managing spectrum and matching application specific requirements to real-time spectrum characteristics so that more optimal use of the available spectrum may be made. At least a first spectrum agent is assigned to each of the plurality of different applications, for managing channels allocated to the application, and a spectrum manager allocates frequency channels to the plurality of different applications based on the following at least one of parameters of a frequency channel required to implement the application and predetermined requirements based on time of day demand changes for the application.
