  • Patent number: 8416570
    Abstract: An open frame chassis has a top opening and a bottom opening permitting ambient airflow. A plurality of modules, each enclosing electrical components in thermal contact with a heat sink area of their corresponding module, can each be inserted in the chassis. Ambient air may flow from the bottom opening across the heat sink area of each module to the top opening to passively cool the modules and electrical components. Key pins guide the modules into place and prevent incorrect insertion of a different type of electrical module not corresponding to the electrical connection of the chassis for that slot. Guide pins on corners of the modules mate with guide holes in the chassis to secure the module to the chassis and decrease vibration. Both sides of the chassis have side openings through which the fins of the modules in the end slots of the chassis may be exposed.

  • Patent number: 8285211
    Abstract: Wireless personal area network (Zigbee, Bluetooth, UWB) and wireless identification technologies (Near Field Communication (NFC), Radio Frequency Identification (RFID)) are implemented in particular client server functions and communications. Connected with an Authentication Server, a wireless HUB authenticates user identification and provides the user with access to secure data communication with a wireless terminal such as a cellular phone or a PDA. A Location Server provides user locations via methods such as RSSI, TDOA, and GPS and sends location information to a Center Control Server and the Authentication Server. With location information, the Center Control Server initiates and optimizes secure information processes and coordinates the functions of servers and user terminals.

  • Patent number: 7974093
    Abstract: An open frame chassis has a top opening and a bottom opening permitting ambient air flow there through. A plurality of modules, each enclosing electrical components which are in thermal contact with a heat sink area of their corresponding module, and each of which can be inserted to an inserted position in the open frame chassis. When the modules are inserted into the open frame chassis, ambient air may flow from the bottom opening of the chassis across the heat sink area of each module to the top opening in order to passively cool the modules and the electrical components enclosed therein. The heat sink area has fins which are separated by a distance of 9 mm to 12 mm and have a height 10 mm to 20 mm. Key pins are associated with the electrical connectors of the chassis to guide the modules into place and prevent incorrect insertion of a different type of electrical module not corresponding to the electrical connection of the chassis for that slot.

  • Publication number: 20110081057
    Abstract: Digital Subtraction Angiography (DSA) is widely used in the diagnosis and treatment of coronary arterial diseases such as arterial stenosis. However, the application of DSA for the assessment of stenosis severity is limited by the high intraobserver and interobserver variabilities associated with the visual assessment of stenosis severity from a cineangiogram (e.g., a sequential series of images after injection of a contrast media). The advent of Quantitative coronary angiography (QCA) has significantly reduced this limitation.

  • Patent number: 7437127
    Abstract: A wireless coverage map of a wireless network is generated as a function of a location of at least one access point and a first signal data collected at a plurality of locations within the network. The first signal data includes a first signal strength of a wireless signal communicated between the at least one access point and a wireless device. A second signal data is received. The second signal data includes a second signal strength of a further wireless signal communicated between one of the at least one access point and a further wireless device. The existence of the predetermined wireless network coverage condition is determined as a function of the second signal data and the wireless coverage map.

  • Patent number: 7155239
    Abstract: A method for estimating a location of a wireless device in a wireless local network is provided. The method includes forming a first set comprised of the signal strength received from access points that the wireless device received a signal from and an indicator of no signal strength measured for access points that the wireless device did not receive a signal from. Next, a scan subset can be formed comprised of access points in the first set that has associated signal strength. Next, a cluster comprised of the calibration points can be formed based on the scan subset. A distance between the first set and each of the calibration point in the cluster can be calculated. Then, the smallest distance can be selected as the location estimate.
