摘要： A drilling area network hub is located proximate to a drill rig and includes an uphole transceiver in bidirectional communication with a downhole transceiver by utilizing the drill string as an electrical conductor. Certain information is collected including rig-based and/or location information. At least one field report is generated based on the certain information to characterize at least one of an inground operation, an operational condition of the downhole transceiver, an operational condition of the uphole transceiver, and an operational condition of the drill rig. A drilling area network server receives the field report from the Internet at a remote location and can generate a custom report and/or recommended actions based on field data. Region specific parameters can be applied to the operation of a drilling system. The drilling area network hub can transfer data logs to the remote location according to assigned priorities.

The method also includes calculating a second error correction code corresponding to a second error profile and generating (112) a second FEC packet to produce the second error correction code. Further, the method includes transmitting a stream of data packets including the plurality of IP video data packets, the first FEC packet and the second FEC packet, to a re-generator (114) of an Internet Protocol video transport system, where an arbitrator of the re-generator identifies an error in the plurality of IP video data packets and selects one of a plurality of inverse FEC functions to correct the error.

摘要： A radio communications device (102) that has multiple receive antennas processes received data communications signals to select between space time coding and spatial multiplexing as a selected transmission technique from a base device (104) that has multiple transmit antennas. A channel throughput (402-412, 450-454) for each transmission technique is estimated based on signal to interference and noise ratios (502-512, 550-554) of signals being transmitted through a MIMO channel (140) as measured by a receiver (708). The transmission technique with the higher estimated throughput is determined. If spatial multiplexing is determined to have the higher estimated throughput and the throughput of each layer of the spatially multiplexed signal is greater than a threshold, spatial multiplexing is selected. Otherwise, space time coding is selected.

摘要： A wireless communication method and apparatus for detecting and decoding enhaiced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions (202) and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test (204). The WTRU then generates an acknowledgement (ACK) message or a non acknowledgement (NACK) message based on the detected H-ARQ indicator (206). A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

摘要： A method for ACK/NACK determination reliability for a communication device includes a first step of defining (602) a supplementary indicator of message acceptability. A next step includes sending (604) data from a communication device to a BTS on an uplink channel. A next step includes checking (606) the data to see if it was properly received. A next step includes providing (608, 612) the supplementary indicator of message acceptability to the communication device in addition to ACK/NACK information.

摘要： The system allows an apparatus, such as a game computer or a PDA, to establish communication between a local application and applications in at least one other apparatus. Active activation means (310) of apparatus (100) invites applications in the other apparatuses to join a selected application by using message sending means (200) to broadcast a frame, requesting the activation of the selected application. The active activation means (310) also determines a communication channel which coresponds to the application. Upon receiving the broadcast frame via message receiving means (210), passive activation means (340) in other apparatuses (101 e.a.) prepare for communication via the corresponding communication channel if a local application needs to be activated. The group of applications, which in this way has been formed, communicates by using group frames. The group frames comprise a channel field which identifies a communication channel. The formed group of applications uses the communication channel which corresponds to the selected application in apparatus (100).

摘要： An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station (Figure 6) to a receiving station (Figure 7). Each of the stations has a control counter (310) and (316) each of which toggles between a logic 0 and 1. The control counter for the transmitter (310) and the receiver (316) are phase locked so that all errors may be corrected. The receiver echoes each data bit back to the transmitter which compares the echoed data to the transmitted data. If there is a match (100), the transmission was successful. If there is no match, the data must be retransmitted. A retransmit control character RTXx is sent to indicate that the receiver should discard the previous character and prepare for a retransmission of the character having the error. Under the proper circumstances and if the counters are still phase locked, the receiver then discards the previously stored character and inverts the counter. If the receiver detects that it has received an erroneous character, such as one having multiple or no PPM pulses, the receiver will simply respond with the reject control character REJ. In such a case, the transmitter will respond with an RTXx which causes the receiver to discard the previously stored character and invert the counter.

摘要： In known remote-controlled electronic appliances for entertainment, the execution of a command is displayed on the appliance. The displays are sometimes difficult to read at distance. The aim of the invention is to provide the user with a visible display of essential information on the remote control unit itself. A sender arranged in the remotely controlled appliance comprises a control logic which transmits, cyclically and with intervening pauses, current operating and setting data of the appliance to the remote control unit, which is equipped with a receiver. These data can be read in a display field in the remote control unit. Application to remote-controlled electronic appliances for entertainment.
