  • Patent number: 7145267
    Abstract: A switching circuit operative to switch between a first and second power source to an output is disclosed. The circuit comprises a MOSFET switch electrically connected to the first and second power sources and operative to provide power from either one of the power sources to the output. The circuit includes a RC network electrically connected to a gate of the MOSFET switch. The RC network is operative to delay switching between the first and second power sources such that the second power source has the opportunity to fully ramp-up in order to provide continuous power to the output. Accordingly, the second power source can fully provide power to the output when the power is switched from the first power source to the second power source.

  • Patent number: 7142507
    Abstract: The purpose of the present invention is to provide a datagram transfer network that can operate stably by avoiding a state of congestion collapse by utilizing information derived from evaluating the impact of datagrams on the operation of the network. To achieve this objective, the results of evaluation is expressed as a preference value related to datagrams, and are inserted in the header in each datagram so that the datagrams are processed by an approach other than the methods based on arrival sequence of datagrams, when derived to the destination indicated in the header. In this approach, datagrams are protocol is controlled by priority order derived from the preference value which reflects traffic information obtained by a traffic monitoring equipment.

  • Patent number: 7136045
    Abstract: A low-cost tactile feedback mouse device for providing haptic feedback to a user for enhancing interactions and manipulations in a graphical environment provided by a computer. The mouse device includes a sensor device able to detect the movement of the mouse in the planar workspace. An actuator is coupled to the housing of the mouse and applies an inertial force in a particular degree of freedom, preferably along an axis perpendicular to the planar workspace, where the inertial force is transmitted through the housing to the user. The actuator outputs the inertial force preferably by linearly moving an inertial mass along the Z-axis. The output force is correlated with interaction of a controlled graphical object, such as a cursor, with other graphical objects in a graphical environment displayed by the host computer. The inertial force can be a pulse, vibration, texture force, or other type of force.

  • Patent number: 7131073
    Abstract: A method and apparatus for providing a click surface in a graphical environment, such as a graphical user interface, implemented on a host computer for use with a force feedback interface device. A displayed cursor is controlled by a user-moveable user object, such as a mouse, of the interface device. A click surface is displayed with an associated graphical object, such as a graphical button or an edge of a window, icon, or other object. When the click surface is contacted by the cursor, a force is output opposing movement of the user object in a direction into the click surface and into the graphical object. When the user object has moved to or past a trigger position past the contact with the click surface, a command gesture signal is provided to the host computer indicating that the graphical object has been selected as if a physical input device on the user object, such as a button, has been activated by the user.

  • Patent number: 7123620
    Abstract: A global path identifier is assigned to each explicit route through a data communication network. The global path identifier is inserted into each packet as the packet enters a network and is used in selecting the next hop. When encountering a new selected path, an ingress router sends an explicit object to downstream nodes of the path to set up explicit routes by caching the next hop in an Explicit Forwarding Information Base (“EFIB”) table. Ingress routers maintain an Explicit Route Table (“ERT”) that tracks the global path identifier associated with each flow through the network. Multiple flows using the same path can be implemented by sharing the same global path identifier. In case of sudden network load changes, rerouting can be performed by changing the global path identifier associated with those flows that need to be rerouted and by then transmitting a new path object to downstream nodes.

  • Patent number: 7113166
    Abstract: A haptic feedback device including a fluid viscosity-controlled brake that outputs high forces to the device user at low cost while maintaining inherent safety. An interface device includes a manipulandum physically contacted by the user. A sensor senses a position of the manipulandum and outputs a sensor signal. The interface device also includes a brake including a field-controlled fluid having a viscosity that can be controlled by controlling an electric current in a coil, where a resistive force or drag on the manipulandum is controlled by controlling the fluid's viscosity. The fluid can be an electrorheological fluid controlled by an electric field or a magnetorheological fluid controlled by a magnetic field. In one preferred embodiment, the resistive force is controlled by adjusting a degree of contact of the brake with the manipulandum based on the fluid's viscosity. Disclosed embodiments include fishing devices, bicycle simulators, and control knobs.
