    摘要: A method, system and apparatus for detecting soft errors in non-dataflow circuits. In a preferred embodiment, input is received at a latch system. The latch system consists of two pairs of latches. The second pair of latches is parallel to the first pair of latches. Both pairs of latches capture the input. However, the second pair of latches captures the input later in time relative to the first pair of latches latch. The captured input is then transferred from the first latch in each pair of latches to the second latch in each pair of latches. A comparison is made of the input in the two second latches. If the input captured in the two second latches is not the same, then a message is sent to a recovery unit.

    摘要: A CAM system is disclosed in which compare data, for example an address translation request, is provided as input search data to a search line generator. The search line generator presents search line input data, through a buffer, to CAM and RAM array systems that include dynamically precharged and evaluated memory cells. Timing sequences in the CAM system are controlled by a series of individually triggered one shot pulse generators. The one shot pulse generators control the timing of CAM system activities, for example the precharge of CAM subsystems, so that these activities are staggered in time. This timing approach improves power consumption and evaluation time within the CAM system. By distributing precharging activities in time throughout the CAM cycle, current peaking during the CAM cycle is reduced. The CAM system latches results in an output latch that is controlled by a one shot pulse generator.

    摘要: A system and related method for generating a test signal with controllable amounts of signal jitter includes a pattern generator, a programmable arbitrary waveform generator (AWG) and a phase modulator. The pattern generator is configured to generate a data signal characterized by a given data pattern, bit rate and pattern length. A trigger signal representative of initial timing information associated with the data signal is provided to the AWG which subsequently generates a modulation signal with a frequency equal to the bit rate divided by the pattern length of the data signal. This modulation signal is provided to the phase modulator, along with a reference clock signal, and the phase modulator generates a modulated clock signal controlled by a phase modulation means (e.g., a controllable delay line) fed by the modulation signal. The resultant jittery clock signal is then provided to the pattern generator to adjust the timing of the data signal and to generate a signal representative of a data signal with data-dependent jitter characteristics. Additional inputs to the delay line of the pulse generator may include a random Gaussian noise signal for providing random jitter and a periodic signal for providing periodic jitter.

    摘要: The present invention provides a deflectable catheter-based system for assisting in the delivery of therapeutic agents, cellular materials and the like to one or more sites in a target body tissue. The system provides for one or more injections to a predetermined needle insertion depth with a single core needle that can be advanced and retracted from the tip of the catheter. The catheter assembly includes a handle subassembly having a mechanism for setting and limiting the depth of insertion of the needle, a slide for moving the injection needle between retracted and extended positions, a return spring for biasing the needle to the retracted position, and a modified pulley mechanism for compensating for catheter shaft compression when the catheter is deflected.

    摘要: Providing multiple line functionality using alternative network telephony is disclosed. A local telephone installation comprises a first local telephone equipment associated with a first local node, a second telephone equipment associated with a second local node, and local telephone wiring connected to the first and second local nodes. The local telephone installation is associated for purposes of the public switched telephone network (PSTN) with a single telephone line. A request from a calling party to establish a connection with the local telephone installation is received at a third local node. It is determined whether the calling party desires to establish a connection to (1) a first telephone extension associated with the first local node or (2) a second telephone extension associated with the second local node. A connection is established from the third local node to the desired extension over the local telephone wiring in a manner that does not affect the other extension.

    摘要: A communication system is provided which permits of communication between an deployed implantable medical device (IMD) and a large-scale powerful computer capable of manipulating complex nonlinear modeling of physiologic systems, and also capable of accounting for large amounts of historical data from a particular patient or a cohort group for improved modeling and predictive power, which may be expected to lead to improved patient outcomes. A deployed IMD may be polled by a routing instrument external to the host patient, and data may be received by wireless communication. This data may be transmitted to a central large-scale or other relatively powerful computer for processing according to an appropriate model. A treatment or instruction regimen, as well as appropriate firmware or software upgrades, may then be transmitted to the routing instrument for immediate or eventual loading into the IMD via wireless communication.

    摘要: Method and system for encrypting streamed data employing fast set-up single use keys and self-synchronization. A transmitting handset produces a bitstream of voice data containing the session key and encrypted by an encryption signal based upon the session key. A receiving handset decrypts the incoming bitstream using the encryption signal and recognizes the session key, thereby establishing synchronization. The session key is derived from a seed by applying a first function to the seed. Following the call, the session key is converted into a new seed by application of a second function and the new seed is stored for use in the next call.
