Concurrent timed digital system design method and environment

The present invention relates to the design of an essentially digital system. As one example of digital systems, these may perform real-time transformations on time discrete digitized samples of analogue quantities. An example of such a system is a digital communication system. The transformations on the data can be specified in a programming language and executed on a processor such as a programmable processor or directly on application specific hardware. In accordance with the present invention the digital system is described as a set of threads in a description language. Alternative names for a thread are tasks and processes. The set of threads defines a representation or model of the digital system. In accordance with the present invention, the representation or model is preferably executable at each stage of the design independent of the current level of abstraction of that representation or model. With description language is meant a programming language. In accordance with the present invention each of the threads has a variable having an assignable value which represents the “local time” of said thread, i.e. a time associated only with that thread, which can be used for sequencing the processing of that thread with respect to other threads. With the word “local” is meant that the time is an attribute of the thread only. In accordance with the present invention a means is provided for the designer to assign a delay to each thread or operation within a thread, this delay representing for instance the processing time for the respective operation or thread on a processing engine, e.g. a computer. By this means, not only can the processing of threads be scheduled but also the designer may assign a value representative of an elapsed time for the processing of a thread or operation on a processing engine. In addition, the threads may be refined concurrently, while still keeping their local time so that after the refining process the new representation of the digital system is executable, i.e. the processing of the refined threads can be scheduled without divergence from the specification.

ActiveUS20090062813A1Improve surgeon performanceImprove medical performanceProgramme controlProgramme-controlled manipulatorManipulatorEngineering
A slave manipulator manipulates a medical device in response to operator manipulation of an input device through joint control systems. The stiffness and strength of the slave manipulator are adjustable according to criteria such as the mode of operation of the slave manipulator, the functional type of the medical device currently being held by the slave manipulator, and the current phase of a medical procedure being performed using the slave manipulator by changing corresponding parameters of the control system. For safety purposes, such changes are not made until it is determined that it can be done in a smooth manner without causing jerking of the medical device. Further, an excessive force warning may be provided to surgery staff when excessive forces are being commanded on the slave manipulator for more than a specified period of time.

Scheduling the dispatch of cells in multistage switches

A multiple phase cell dispatch scheme, in which each phase uses a simple and fair (e.g., round robin) arbitration methods, is described. VOQs of an input module and outgoing links of the input module are matched in a first phase. An outgoing link of an input module is matched with an outgoing link of a central module in a second phase. The arbiters become desynchronized under stable conditions which contributes to the switch's high throughput characteristic. Using this dispatch scheme, a scalable multiple-stage switch able to operate at high throughput, without needing to resort to speeding up the switching fabric and without needing to use buffers in the second stage, is possible. The cost of speed-up and the cell out-of-sequence problems that may occur when buffers are used in the second stage are therefore avoided.

Method and apparatus for measurement of neural response

A method for measuring a neural response to a stimulus. Measurement circuitry is settled prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.
