Abstract: This invention provides transgenic plant cells with recombinant DNA for expression of proteins that are useful for imparting enhanced agronomic trait(s) to transgenic crop plants. This invention also provides transgenic plants and progeny seed comprising the transgenic plant cells where the plants are selected for having an enhanced trait selected from the group of traits consisting of enhanced water use efficiency, enhanced cold tolerance, increased yield, enhanced nitrogen use efficiency, enhanced seed protein and enhanced seed oil. Also disclosed are methods for manufacturing transgenic seed and plants with enhanced traits.

Abstract: A valve assembly connects into a drill string for opening and closing at least one inner passage within the drill string of the drill string. The valve assembly includes an annular valve assembly carried in an annular passage that moves between the open and closed positions in response to downward fluid pressure from the surface through the annular passage. The valve assembly also includes an inner valve assembly carried in an inner passage of the drill string. The inner valve assembly is a two-way valve that is actuated between open and closed positions by pressure pulses from the surface through the inner passage. The valve assembly can be used within coiled tubing.

Abstract: A valve assembly connects into a drill string for opening and closing a passage within the drill string. The valve assembly has an inner valve member for opening and closing an inner passage of the drill string. The valve member moves between the open and closed positions in response to axial movement of the drill string. Lifting the drill string causes the upper portion to move upward relative to the lower portion, bringing along with it the valve member, while the valve sleeve remains stationary with the lower portion, opening the valve. The valve assembly can include an annular valve assembly for opening and closing an annular passage located around the inner passage. The annular valve assembly is opened and closed by increasing the pressure in the annular passage above the annular valve assembly.

Abstract: Two types of contention channels are used to accommodate broadband packet data in a satellite communication network. A first contention channel is used by unsynchronized user terminals to access the system and request a traffic channel. The first contention channel is of a sufficient duration to accommodate a RACH message, as well as the timing uncertainty between user terminals within a given spot beam. A second contention channel is shorter in duration than the first contention channel, and is narrowband, so that more than one second contention channel may be transmitted within the bandwidth of the broadband traffic channels. The second contention channels are used by synchronized user terminals for transmitting packet RACH, or PRACH, messages. The more efficient nature of the PRACH channels accommodates the increased overhead associated with bursty packet data, without the capacity cost of the longer duration RACH channel.

Abstract: An approach for immediate channel assignment in a wireless communications system involves receiving a channel request message from a wireless transceiver, the channel request message including a dialed party number; forming an immediate assignment message including a channel assignment; transmitting the immediate assignment message to the wireless transceiver; and establishing a communications channel between the wireless transceiver and a called party by establishing a channel between the wireless transceiver and the called party.

Abstract: An approach for error flow control in a communications system involves receiving a plurality of frames of data; determining in said plurality of frames of data, two or more contiguous defective frames of data, the two or more contiguous defective frames of data being followed by at least one frame of data in said plurality of frames that is not defective; forming a group reject message indicative of a range of the two or more contiguous defective frames; transmitting the group reject message; and receiving replacement frames, the replacement frames corresponding to the two or more contiguous defective frames, wherein said at least one frame that is not defective is not received again in response to the group reject message.

Abstract: An approach for selecting an asynchronous paging interval involves selecting a set of possible paging schemes for one wireless system; selecting a paging interval for another wireless system that is asynchronous with the paging schemes selected for the one wireless system; determining, after some number of paging repetitions, the probability of collision between a first paging channel in the one wireless system, and a second paging channel in the other wireless system; reselecting the paging interval for the other wireless system, asynchronous with the paging schemes selected for the one wireless system, and repeating the determining of the probability, until after some number of page repetitions, the probability reaches a prescribed minimum; and reselecting the paging interval for the other wireless system, asynchronous with the paging schemes selected for the one wireless system, and repeating the determining of the probability, until the number of paging repetitions needed to reach the prescribed minimum i
