  • Publication number: 20130314447
    Abstract: A calibration system may be provided for calibrating displays in electronic devices during manufacturing. The calibration system may include calibration computing equipment and a test chamber having a light sensor. The calibration computing equipment may be configured to operate the light sensor and the display to gather display intensity performance data for obtaining a display gamma model. The display intensity performance data may be gathered using a range of display control settings that will be used in performing color calibration operations for the display. The calibration computing equipment may be configured to operate the light sensor and the display to gather display color performance data for determining a display white point calibration. Display white point calibration data may be provided to the electronic device and stored in volatile or non-volatile memory in the device or may be permanently stored in circuitry associated with the display.

  • Publication number: 20130018624
    Abstract: During manufacturing, devices under test may be tested at test stations. Test cables may be used to couple the test stations to the devices under test. To ensure that cables have been assembled properly, a test system may be used to convey test data through the cables. Status indictors in the cables can be activated using the test data. The test system may include a test board for performing loop-back tests. During testing, test data may be transmitted through the cable to the test board. The test board may convert the test data from a first format such as a Universal Serial Bus format to a second format such as a Universal Asynchronous Receiver Transmitter format. Test signals that have been received by the test board may be sent back to the cable to direct the cable to activate the status indicators.

  • Publication number: 20120290246
    Abstract: A test system may include test stations for testing a device under test. The test stations may each include test equipment that may be connected to a device under test using a test cable. The test cable may include a status indicator to indicate when tests have been passed or have failed. A first connector at one end of the test cable may be coupled to the test equipment. A second connector at an opposing end of the test cable may be coupled to the device under test. Communications through the first connector may use a first communications protocol. Communications through a first set of contacts in the second connector may use the first communications protocol. Communications through a second set of contacts in the second connector may use a second communications protocol.

  • Patent number: 8194593
    Abstract: An embodiment is a technique to perform QoS. An interface between an upper layer and a lower layer in a multi-hop mesh network receives and transmits packets from and to a local node and a remote node. A classifier classifies the received packets into a plurality of packet types having different priority levels. A queue manager manages a plurality of buffers organized according to the packet types. The plurality of buffers stores the classified packets based on the packet types. A scheduler schedules distributing the packets from the plurality of buffers based on the priority levels according to a scheduling policy.

  • Publication number: 20110280156
    Abstract: An apparatus and method for a wireless home mesh network with a network topology visualizer is described. In one embodiment, the method may include collecting node topology information by a node of a wireless home mesh network, where the node topology information includes a list of neighbor nodes for the node. Thereafter, a communication socket is opened, and a node topology packet, including a lust of neighbor nodes, is transmitted in order to produce a global network topology map. Other embodiments are described and claimed.

  • Patent number: 7990897
    Abstract: An apparatus and method for a wireless home mesh network with a network topology visualizer is described. In one embodiment, the method may include displaying the network topology of a wireless home mesh network. The mobile nodes and stationary nodes of the wireless home mesh network may wirelessly communicate to share topology information regarding the wireless home mesh network. The topology information may include local connectivity information of a node, such as the direct neighbors of the node and the neighbors' neighbor information. In one embodiment, the local connectivity information is combined with the received node information to form an interactive global topology map of the wireless home mesh network to display for a user. In another embodiment, the combined topology information may be stored for offline processing. Other embodiments are described and claimed.

  • Publication number: 20100232370
    Abstract: An embodiment is a technique to perform network-based traffic recognition and packet classification. A port identifier in a transport layer header of a packet having a packet type associated with a priority level is extracted. The packet is transmitted from or to an application according to a network protocol in a multi-hop mesh network having a local node and a remote node. The packet is classified into the packet type using one of a pre-defined port list, a dynamic port table, and an application header of the application.
