摘要:
An approach is disclosed for a satellite terminal to utilize a lower transmit rate when transmission conditions do not permit the terminal to successfully transmit at a higher, preferred service rate. The terminal monitors retransmissions to determine whether transmission is possible at the higher rate. As an initial measure, the terminal first tries another inroute (or inroute group) at the preferred service rate before any attempt to switch to a lower service rate. If this other inroute group still poses a problem for successful transmission, the terminal switches to a lower service rate. The terminal remains at the lower service rate for a predetermined, configurable amount of time. This arrangement has particular applicability to a satellite network that provides data communication services.

A system for directing an antenna for transmission over a two-way satellite network is disclosed. A transceiver is coupled to the antenna; the transceiver transmits and receives signals over the two-way satellite network. A user terminal is coupled to the transceiver and executes an antenna pointing program. The program instructs a user to initially point the antenna to a beacon satellite using predefined pointing values based upon the location of the antenna. The program receives new antenna pointing parameters that are downloaded from a hub over a temporary channel that is established via the beacon satellite. The program displays the new antenna pointing parameters and instructs the user to selectively re-point the antenna based upon the downloaded new antenna pointing parameters.

An apparatus and method for using a bandwidth (BW) allocation in a Time Division Multiple Access (TDMA) network. The method includes filling a buffer having a buffer length with a demand-inducing stream data until either the demand-inducing stream data is exhausted or the buffer length equals the BW allocation, determining a leftover BW as the BW allocation minus the buffer length after the filling, composing a leftover buffer when demand-deferring stream data is present, where the leftover buffer includes a transmission header (TH) and a transmission data (TD) includes a portion of a demand-deferring stream data, and transmitting the buffer and the leftover buffer in a time slot associated with the BW allocation. In the method, a length of the TH plus a length of the TD is less than or equal to the leftover BW.

A system or container for delicate baked goods is provided from two mating parts: a top part including a plurality of domes and a bottom part formed with a plurality of wells. When the two parts are mated, the domes and wells cooperate to form cavities for the individual baked goods, each baked good being grasped or secured within each cavity by a press nip to insure that the delicate crown of the baked good is not damaged.
