Abstract:
A mesh node of an infrastructure wireless local area network ‘WLAN’ is coupled to a battery which is coupled to a device that is able to harness energy from a source of renewable energy. Energy management of the mesh node includes conducting simulations of a system comprising the mesh node, the device, and the battery in its current state of charge, determining an admissible load for the mesh node from the simulations, and withholding communication services by the mesh node for one or more periods of time a cumulative duration of which is related to power consumption of the mesh node when handling the admissible load. The simulations involve meteorological data related to the source of renewable energy in the vicinity of the mesh node.
Abstract:
The present invention provides a cross linked polyolefin thermoset material, comprising maleic anhydride functionalized reactive polyolefin wax cross linked with a polyamine. The thermoset may be made by a method involving reaction of a maleic anhydride functionalized reactive polyolefin wax with a polyamine. The polyolefin may be polyethylene, polypropylene and their copolymers. The polyamine is a primary or secondary alkyl polyamines, alkyl ether polyamines, aryl polyamines. Polyols may be used instead of polyamines, for example alkyl polyols, alkyl ether polyols or aryl polyols.
Abstract:
A network support node which includes a local area network (LAN) interface and a cellular RF interface is provided. The LAN interface is configured to connect the network support node as a LAN node in a LAN. The cellular RF interface is configured to provide wireless communications over a wireless communication link with a base station of a cellular network, such that the network support node operates as a client end station with the base station. The network support node receives, from the LAN via the LAN interface, data of a communication session between a mobile communication device and another communication device. The network support node communicates with the mobile communication device, via the cellular RF interface over the wireless communication link with the base station, the data of the communication session.
Abstract:
A mobile robotic surgical system which includes a mobile surgical robot for use in a mobile or confined environment and a control station in communication with the mobile surgical robot over a network. The mobile surgical robot includes a controller for controlling operation of the mobile surgical robot, a communications subsystem for communicating with the control station over the network, robotic surgical instruments controllable by the control station over the network, a detector subsystem for determining spatial information relating to a surgical environment of the surgical robot, and a motion stabilizer subsystem for facilitating operation of the robotic surgical instruments while the mobile environment is in motion. The controller is configured to operate a local control loop between at least one of the subsystems and the robotic surgical instruments.
Abstract:
The present disclosure includes a method of determining the presence of a target in a sample comprising an allosteric DNAzyme; rolling circle amplification dependent on the activity of the allosteric DNAzyme in the presence of target and a detection system. The methods further comprise quantifying the amount of target in the sample by comparing the detection with a control. Also included herein are kits for practicing the methods described herein and methods of designing biosensor systems.
Abstract:
Methods and systems of controlling transmit power in a multi-user wireless communication system is provided, A transmit power, level for a transmitter is determined according to an algorithm based in communication theory, such as an iterative water-filling procedure, which takes into account an assumption of transmit behaviours of transmitters in the communication system. Actual transmit behaviours of transmitters in the communication system are monitored using a learning algorithm to determine whether any transmitters exhibit transmit behaviours which are not consistent with the assumption.
Abstract:
If a handoff by a mobile station currently associated with a particular access point is probable, then the particular access point sends an activation alert to one or more other access points. An access point receiving the activation alert that is in a low-power state enters a higher-power state. An access point receiving the activation alert that is in a higher-power state, remains in that higher-power state.
Abstract:
A wireless access point advertises data rates that it supports. A mobile station is permitted to communicate with the access point at one or more of the lower data rates only if the mobile station satisfies one or more conditions.
Abstract:
A method is presented for adapting the packet size for VoIP communications, determined on-the-fly by the total network delay inherent at the time of packet transmission. If network delays are small relative to the maximum permissible latency for VoIP communications, the payload size per packet may be increased to maximize efficiency for the transmitted call. Alternatively, if network delays are large, the payload size per packet may be decreased in order to assure that the perceived quality of the transmitted call is acceptable.
Abstract:
A wireless local area network includes multiple access points with overlapping coverage, and modes of different power consumption are available to the access points. It is assessed whether the traffic load of the network may be adequately supported using fewer access points in an active mode. If so, the traffic load is redistributed from certain active access points among the remaining access points in the active mode. The certain access points are switched into a mode of lower power consumption than the active mode. Similarly, it is assessed whether the traffic load of the network is adequately supported by the current number of access points in an active mode. If not, certain access points which are in a mode of lower power consumption are switched to the active mode. The traffic load is redistributed among the access points in the active mode including the certain access points.
