  • Publication number: 20190054316
    Abstract: In certain embodiments novel sparse orthogonal collimators (SOCs) for use in radiotherapy are provided. In certain embodiments the SOCs comprise 2 layer 4 bank orthogonal collimators with 2-8 leaves in each of the 4 banks. Instead of using the limited heuristic approach to create jaw-only IMRT, a novel fluence map optimization method is provided based on wavelet decomposition and this method is used for IMRT. An algorithm to simplify the fluence maps with minimal and predictable dose quality compromise is also provided.

  • Publication number: 20170353245
    Abstract: Described are systems, devices, and techniques for extending wireless networks and associated systems, devices, and techniques for determination of optimal locations of a wireless range extender, such as by evalauating a quality of a wireless signal originating from a wireless gateway or access device and determining whether an alternative placement of a wireless range extender would result in improved quality. Also described are systems, devices, and techniques for automatically grouping multiple bands of a single wireless access device as well as systems, devices, and techniques that simplify connection of wireless devices to a wireless access device, such as by evaluating wireless messages transmitted on different bands to determine that the wireless messages originate from the same wireless access device.

  • Patent number: 9163811
    Abstract: An illumination module is provided that can be inserted into a receptacle that includes a wall and may be mounted on a support surface, such as a heat sink, and the illumination module include a cover and an LED assembly rotateably coupled to the cover. The LED assembly seats within the receptacle which causes terminals of the LED assembly to align with contacts on the receptacle. One of the cover and the receptacle can have a plurality of ramps and the other a plurality of shoulders. The cover can be rotated relative to the receptacle to cause the shoulders to slide relative to the ramps so as to direct the LED assembly into the receptacle. When the LED assembly is attached to the receptacle, the terminals on the LED assembly mate with the contacts on the receptacle.

  • Patent number: 9097405
    Abstract: A light module system includes a receptacle, which may be mounted on a support surface, such as a heat sink, and further includes a cover and an LED assembly rotatably coupled to the cover. The LED assembly seats within the receptacle which causes terminals of the LED assembly to align with contacts on the receptacle. One of the cover and the receptacle has a plurality of ramps and the other has a plurality of shoulders. The cover can be rotated relative to the receptacle to cause the shoulders to slide relative to the ramps so as to direct the LED assembly into the receptacle. When the LED assembly is attached to the receptacle, the terminals on the LED assembly mate with the contacts on the receptacle.

  • Patent number: 8974080
    Abstract: An illumination module is provided that can be inserted into a receptacle with a ramp that includes a wall and may be mounted on a support surface, such as a heat sink, and the illumination module include a cover and an LED assembly rotateably coupled to the cover. The LED assembly seats within the receptacle which causes terminals of the LED assembly to align with contacts on the receptacle. Circuitry is provided in the module that accepts an input voltage and converts the input to a desired driving output. The cover can be rotated relative to the receptacle so as to engage ramps so as to direct the LED assembly into the receptacle. When the LED assembly is attached to the receptacle, the terminals on the LED assembly mate with the contacts on the receptacle.

  • Patent number: 8820342
    Abstract: A device for controlling an actuator includes an input interface that receives a plurality of input signals including a setpoint command signal and a feedback signal. An output interface provides a drive signal to the actuator. First, second, and third redundant loop controllers processes the setpoint command signal and the feedback signal to generate respective actuator control signals. A primary controller compares the actuator control signals to determine whether at least two are substantially similar. The device outputs the drive signal to the actuator according to an actuator control signals that has been determined by the primary controller to be substantially similar to another. Any one of the redundant loop controllers is hot swappable with a replacement loop controller such that loop controller redundancy is operatively maintained by the device in controlling the actuator while one of the redundant loop controllers is hot swapped.

  • Patent number: 8650311
    Abstract: A smart network may include a smart network host device as well as one or more client devices configured to connect to the smart network. Each of the client devices may implement one or more services that the client device exposes to other devices connected to the smart network. A client device configured to connect to the smart network may implement one or more modules configured to facilitate connecting to the smart network, registering the client device or services running on the client device with the smart network, diagnosing issues with the client device or the smart network, and upgrading the firmware of the client device. The client device may be configured to perform the various operations with minimal input from an owner of the smart network.

  • Patent number: 8631471
    Abstract: A host device for a wireless network may be configured to implement at least two virtual access points for connecting client devices to the wireless network. A user virtual access point enables a client device to connect to the wireless network and transmit network traffic to other devices connected to the wireless network. In addition, a setup virtual access point provides an additional access point to connect to the wireless network when network credentials for the user virtual access point, such as a service set identifier (SSID) or a password, are changed by a user. When a client device cannot find the user virtual access point based on a stored SSID or password, the client device may be configured to automatically reconnect to the setup virtual access point to request a new SSID and network credentials for the user virtual access point.

  • Patent number: 8626921
    Abstract: A smart network may include a smart network host device as well as one or more client devices configured to connect to the smart network. Each of the client devices may implement one or more services that the client device exposes to other devices connected to the smart network. Each of the client devices includes network layer 2 and 3 attributes as well as network layer 7 application attributes. The application attributes are enumerated as named services, which each client device registers with the smart network host device. When a client device needs access to a named service, the smart network host device uses layer 2, 3, and 7 attributes associated with the client device to select a suitable server for providing the named service to the client device.
