Trajectory representation in design and testing of a surgical robot
For kinetic sizing, the dynamic torque to be provided by a robotic system may be based off of, in part, a maximum acceleration. Rather than trying to extract maximum acceleration from many samples, a relationship of velocity to acceleration from repetitive user inputs relative to a non-surgical target in different situations (e.g., accurate, fast, or balance tracing of the target movement) is established. The velocity for any given situation may be used to estimate the acceleration from the relationship. Rather than using many trajectory samples from many users, a synthetic trajectory may be used. The synthetic trajectory may be fit to user data while maintaining high-coverage properties for direction of movement for any given pose of the robot. Alternatively, a virtual trajectory decoupled from time is used. The virtual trajectory samples the directions at any given pose in a global high-coverage manner, without specifically using a time-dependent sequence of poses. |

Then, the base station can allocate a much smaller region containing only those indicated sections, and the ready user devices can send their requests in that smaller region. The base station can then determine which user devices request access, provide them with grants, and receive their messages. By avoiding allocating scheduling-request resources to sections that have no waiting messages, the base station may save time and avoid wasting limited resources, according to some embodiments. |

Mesh communication network provision
A method of provisioning mesh communication networks is disclosed. The method involves simulating the performance of a proposed network design to ensure the proposed network design meets service level criteria before provisioning a network in accordance with the proposed network design. Such simulations are required to be comprehensive because highly improbable events can be sufficient to result in a mesh network not meeting the stringent performance criteria which such networks are required to meet. Known methods of provisioning rely on exhaustively listing the mesh network states which would adversely impact the service offered by a proposed network design as part of simulating the performance of the proposed network design—this is an error prone exercise since relevant network states can be missed. A simulation technique is proposed in which the network state after each event is represented by a weighted graph indicating a measure of path cost for each of the links in the mesh network. A graph searching algorithm is applied to seek a path across the graph, thereby systematically exploring paths over mesh network which could provide a suitable route for the service in the simulated network state represented in the graph. Networks are thus provisioned which meet stringent performance criteria without being over-engineered. |

Dynamically reconfiguring data plane of forwarding element to account for operating temperature
Some embodiments of the invention provide a network forwarding element that can be dynamically reconfigured to adjust its data message processing to stay within a desired operating temperature or power consumption range. In some embodiments, the network forwarding element includes (1) a data-plane forwarding circuit (“data plane”) to process data tuples associated with data messages received by the IC, and (2) a control-plane circuit (“control plane”) for configuring the data plane forwarding circuit. The data plane includes several data processing stages to process the data tuples. The data plane also includes an idle-signal injecting circuit that receives from the control plane configuration data that the control plane generates based on the IC's temperature. Based on the received configuration data, the idle-signal injecting circuit generates idle control signals for the data processing stages. Each stage that receives an idle control signal enters an idle state during which the majority of the components of that stage do not perform any operations, which reduces the power consumed and temperature generated by that stage during its idle state. |

System and method for measuring phase noise
A system and method are provided for measuring absolute phase noise of a test signal from a DUT using a reference source for generating an RF reference signal, a mixer for mixing the RF reference signal and an input signal, an adjustable DC voltage source for outputting a DC voltage, and a PLL for maintaining a 90 degree quadrature between the RF reference and input signals. The method includes mixing RF calibration signals and the RF reference signal to provide calibration phase signals, at least one of the RF calibration signals having one-tone AM modulation; monitoring modulation tone frequency of the one-tone AM modulation; adjusting the DC voltage output by the adjustable DC voltage source to minimize a voltage level of the tone frequency being monitored; mixing the test signal and the RF reference signal to provide a measurement phase signal for measuring absolute phase noise of the test signal. |
