  • Patent number: 7756166
    Abstract: In a transmission system with a transmitter coupled to a receiver a main signal encoded according to a coding property is transmitted together with an auxiliary signal (AUX). In order to transmit the auxiliary signal without needing additional space in the transmission frame, the auxiliary signal is transmitted by changing the coding property according to a predetermined sequence. This is done by means of the sequencer. In the receiver, the decoding of the predetermined sequence is performed by a decoder.

  • Patent number: 7746915
    Abstract: A wireless network employs at least a base station (1 to 3) and a plurality of assigned terminals (4 to 14) for exchanging user data and control data. That base station (1 to 3) includes a device (21, 22) for correlating a signaling sequence transmitted by at least one terminal (4 to 14) to indicate the wish to use a contention channel and for detecting the pulse evolved from a received and correlated signaling sequence. After a signaling sequence has been detected, the base station (1 to 3) transmits a provision message over a contention channel to be utilized by the assigned terminals (4 to 14).

  • Patent number: 7721346
    Abstract: A technology is provided to improve tamper resistance in encrypting data to be secured and inputting/outputting the data between a recording device and a host device. When the recording device issues an input/output command to a storage device to input/output data to be secured, the recording device attaches an ID to the command to identify to which cryptographic input/output processing the command belongs. Upon reception of a sequence command, the storage device receives the command if its ID has been allocated and the command is verified to have been issued in the correct sequence. The sequence ID is used to identify a process system while appropriately managing the steps of executing commands.

  • Patent number: 7715858
    Abstract: A secondary station has a receiver capable of resolving signals received (504,510) as a plurality of multipath signals from a plurality of base stations during a soft handover process. In order to decode and act upon the received signals in a very short period of time, an initial subset of received multipath signals is processed (506) to provide an estimate of the action needing to be taken by the station, which action is then implemented by the station (508). Later arriving signals are processed separately (512) and used to update the estimate, as a result of which the action already taken may be corrected (514). Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification.

  • Patent number: 7685607
    Abstract: The invention provides an embedded processor architecture comprising a plurality of virtual processing units that each execute processes or threads (collectively, “threads”). One or more execution units, which are shared by the processing units, execute instructions from the threads. An event delivery mechanism delivers events—such as, by way of non-limiting example, hardware interrupts, software-initiated signaling events (“software events”) and memory events—to respective threads without execution of instructions. Each event can, per aspects of the invention, be processed by the respective thread without execution of instructions outside that thread. The threads need not be constrained to execute on the same respective processing units during the lives of those threads—though, in some embodiments, they can be so constrained. The execution units execute instructions from the threads without needing to know what threads those instructions are from.

  • Patent number: 7653912
    Abstract: The invention provides, in one aspect, a virtual processor that includes one or more virtual processing units. These virtual processing units execute on one or more processors, and each virtual processing unit executes one or more processes or threads (collectively, “threads”). While the threads may be constrained to executing throughout their respective lifetimes on the same virtual processing units, they need not be. An event delivery mechanism associates events with respective threads and notifies those threads when the events occur, regardless of which virtual processing unit and/or processor the threads happen to be executing on at the time. The invention provides, in other aspects, virtual and/or digital data processors with improved dataflow-based synchronization. A process or thread (collectively, again, “thread”) executing within such processor can execute a memory instruction (e.g.

  • Publication number: 20090223823
    Abstract: A method of separating a protein by gel electrophoresis, which comprises a staining step for bringing a protein-containing sample into contact with a staining liquid containing a staining agent, a surfactant and a buffer solution, and an electrophoresis step for subjecting the protein-containing sample after the staining step to gel electrophoresis. According to the present invention, using a staining liquid containing a surfactant such as SDS and the like, a protein-containing sample can be stained in a short time, and can develop color with high sensitivity. In addition, since an excess staining agent migrates earlier than protein by electrophoresis, a washing operation is not necessary. Furthermore, by staining, after the first dimension electrophoresis, with a staining liquid containing a surfactant such as SDS and the like, the second dimension electrophoresis can be performed immediately.
