  • Patent number: 7102541
    Abstract: A force feedback interface having isotonic and isometric control capability coupled to a host computer that displays a graphical environment such as a GUI. The interface includes a user manipulatable physical object movable in physical space, such as a mouse or puck. A sensor detects the object's movement and an actuator applies output force on the physical object. A mode selector selects isotonic and isometric control modes of the interface from an input device such as a physical button or from an interaction between graphical objects. Isotonic mode provides input to the host computer based on a position of the physical object and updates a position of a cursor, and force sensations can be applied to the physical object based on movement of the cursor. Isometric mode provides input to the host computer based on an input force applied by the user to the physical object, where the input force is determined from a sensed deviation of the physical object in space.

  • Patent number: 7099463
    Abstract: A method and an apparatus provide for determining whether a data terminal equipment (DTE) device represents a compatible device lacking an independent power supply and adapted to be powered using phantom power over a wired connection from a communications device such as a switch. A detection signal may be transmitted from the communications device to an identity network connected to the DTE. A response detection signal may be returned and checked in a receiver at the communications device. A switch may then be closed to provide phantom power if the result of the check indicates that the DTE is a compatible device adapted to receive phantom power. Compatible DTE device may include telephones, Voice over IP (VoIP, IP or Ethernet) telephones, network access devices, computers, and the like.

  • Patent number: 7098498
    Abstract: Hot-electron injection driven by hole impact ionization in the channel-to-drain junction of a p-channel MOSFET provides a new mechanism for writing a floating-gate memory. Various pFET floating-gate structures use a combination of this mechanism and electron tunneling to implement nonvolatile analog memory, nonvolatile digital memory, or on-line learning in silicon. The memory is nonvolatile because the devices use electrically isolated floating gates to store electronic charge. The devices enable on-line learning because the electron injection and tunneling mechanisms that write the memory can occur during normal device operation. The memory updates and learning are bidirectional because the injection and tunneling mechanisms add and remove electrons from the floating gate, respectively. Because the memory updates depend on both the stored memory and the pFETs terminal voltages, and because they are bidirectional, the devices can implement on-line learning functions.

  • Patent number: 7094991
    Abstract: A device is disclosed for warming tortillas and other foods. The device operates with a standard electric alternating current ranging from 110 to 120 volts in the US and 220v–240v in other countries. This appliance is to be used in homes or in businesses for the purpose of warming either corn or flour tortillas in quantities ranging from one up to six at a time. The electric current provides energy to heater elements located within the unit and thus provide the heat necessary to warm the tortillas placed on a plurality of circular loading trays. The loading trays are specially designed to lock-in-place in the open and closed positions and are designed to work with a vertical pivot tube which allows the loading trays a pivot-swivel action for efficiency in the loading and unloading of tortillas.

  • Patent number: 7096164
    Abstract: The automation of design and sale of electronic and mechanical components is accomplished by allowing a user to design a plan for their electronic and mechanical component needs using specialized software. The software utilizes predefined models of components to aid the user in designing a system where all the components are compatible, even in cases where the components are made by different manufacturers. This is accomplished by creating a model for each proposed piece of equipment in the system, the model having properties and rules, wherein the rules define conditions and actions. Then an object is created for each piece of equipment in the system. Selections for values for the properties are received for each of the pieces of equipment. Any rules that have as a condition the properties for which value selections are received are executed. Finally, testing may be undertaken to determine if a proposed configuration is valid by examining results of the rule execution.

  • Patent number: 7096418
    Abstract: A Web page cache that stores Web pages such that servers will be able to retrieve valid dynamic pages without going to a dynamic content server or origin Web server for the page every time a user requests that dynamic page. The dynamic content cache receives information that defines data upon which each dynamic page is dependent, such that when the value of any dependency data item changes, the associated dynamic page is marked as invalid or deleted. The dynamic page cache stores dependency data, receives change event information, and indicates when pages in the cache are invalidated or need to be refreshed.

    Abstract: This invention provides for an apparatus and method to isolate ports on layer 2 switches on the same VLAN to restrict traffic flow. The apparatus comprises a switch having said plurality of ports, each port configured as a protected port or a non-protected port. An address table memory stores an address table having a destination address and port number pair. A forwarding map generator generates a forwarding map which is responsive to a destination address of a data packet. The method for isolating ports on a layer 2 switch comprises configuring each of the ports on the layer 2 switch as a protected port or a non-protected port. A destination address on an data packet is matched with a physical address on said layer 2 switch and a forwarding map is generated for the data packet based upon the destination address on the data packet.

  • Patent number: 7095707
    Abstract: A system for bidirectional communication of digital data between a central unit and a remote unit wherein the need for tracking loops in the central unit has been eliminated. The central unit transmitter generates a master carrier and a master clock signal which are used to transmit downstream data to the remote units. The remote units recover the master carrier and master clock and synchronize local oscillators in each remote unit to these master carrier and master clock signals to generate reference carrier and clock signals for use by the remote unit receiver. These reference carrier and clock signals are also used by the remote unit transmitters to transmit upstream data to the central unit. The central unit receiver detects the phase difference between the reference carrier and clock signals from the remote units periodically and adjusts the phase of the master carrier and master clock signals for use by the central unit receiver to receive the upstream data.

  • Patent number: 7091950
    Abstract: A method and apparatus for providing force sensations in virtual environments includes a human/computer interface device and method used in conjunction with a host computer and which can provide feel sensations to a user of the device. A user manipulatable object physically contacted by a user, such as a joystick, stylus, pool cue, or other object, is movable in multiple degrees of freedom using a gimbal mechanism. A local microprocessor, separate from the host computer, enables communication with the host computer and receives commands from the host, decodes the commands, outputs actuator signals in accordance with commands, receives sensor signals, and reports data to the host in response to commands. Actuators generate feel sensations by providing a force on the user object in response to actuator signals from the local microprocessor, and sensors detect the motion of the user object and reports sensor signals to the local microprocessor.
