摘要:
A wire adapter in a Wireless Universal Serial Bus configuration includes endpoints bound to communication constructs for communicating with discrete identified endpoints of downstream devices. A Virtual Pipe system is provided for the wire adapter to manage the communications pathways between a host and a downstream device connected to the wire adapter. The system provides for establishing data pathways through previously unused endpoints in the wire adapter.

A panel display system having at least one source device coupled to a plurality of display units interconnected to form a larger display having any desired size and shape. Each display unit is a self-contained panel display having a video random access memory (VRAM) for storing image data, a controller for processing data signals to provide the image data to the VRAM, and an image display panel for displaying the image data. The self-contained panel displays substantially reduce the need for a separate driver card for each panel display, and substantially reduce the communications bandwidth between the source devices and the panel displays of the system. Means for interconnecting the display units include the use of data/control bus connectors and power line connectors, cables, network devices, local area networks, and/or wide area networks.

A method and apparatus are disclosed for providing persistent storage of Web resources. Uniform Resource Locators (“URLs”) that identify Web resources are augmented to include a time stamp. A web browser and a web server are disclosed that accommodate a time stamp parameter and allow a user to refer to any Web address with a precise target date. The disclosed Web browser can optionally include a mechanism to facilitate the specification of the desired date and time, or the user can manually append the time stamp to the URL indicated in the “Location” window of the browser. The persistent Web servers (i) receive URLs containing a time stamp, relative or variable time-stamp, (ii) extract the time stamp, (iii) retrieve the appropriate Web page(s) corresponding to the time-stamp, and (iv) return the appropriate page(s) or links to the client. Wildcard characters and date ranges can be used in the variable time-stamp to implement a variable time stamp when a user is not sure of the date for a specific web resource or wishes to specify more than one precise date and time. The persistent Web servers include a persistent archive for storing all of the versions of Web resources that will be persistently available to Web users.

A three-dimensional computer input device includes at least three elastic members which elastically support a movable object in a frame. A two-dimensional position detector is connected to one end of each of the elastic members. As the movable object is moved and/or rotated relative to the frame, the detectors collectively detect the motion and transmit the current position and/or rotational information to a computer which graphically displays the motion on a screen of the computer.

A system and method that identify the location of a wireless terminal. An illustrative embodiment of the present invention comprises a wireless communication system with a plurality of base stations. The system associates a location identification signal with each base station, such as an area code and an exchange of a telephone number in the geographic area of the base station. When a call is connected through a base station, the system modifies the caller-ID signal for the wireless terminal with the location identification signal of the base station. Thus, the system identifies the location of a wireless terminal.

Certified Wireless USB 1.0 (CWUSB) defines two different types of association: cable association and numeric association. In the numeric association, the CWUSB host and device use a specific protocol to exchange the security information. At final stage of this information exchange, both host and device need to display a number asking user's feedback. Once this is done, both host and device will be able to generate the connection key as the shared secret for the following secured communication. One problem of this numeric association method is that device needs to be able to display the numbers. For certain class of device that has capability to display an image, there is a natural way to add this function to them. A method for this class of devices is described. Another kind of association, which is not defined in the CWUSB 1.0, is manual association. User needs only to manually type in the Connection Key coming from the CWUSB device. There are many ways to delivery the key, but it is very easy for device that can display an image.
摘要:
Universal Serial Bus (USB) is a Master/Salve or Host/Device system in which there is only one host and one or more devices connected by cables to the host. To connect a USB device to a different host controller (say another PC), the user unplugs the USB cable and establishes the connection physically by plugging the cable into the new host controller interface. Certified Wireless USB (CWUSB), a logical extension to the USB, preserves the USB connection model, except that the link between the host and the device is now using a wireless technology. A wireless device is usually connected to only one wireless host at a given point of time, even though several wireless hosts may be co-located in the same physical neighborhood. The connection between the wireless host and device is initiated by the device. A device usually selects a wireless host from a stored set of known hosts that have established a trusted relationship with the device. If more than one wireless host is operating in the same neighborhood, there is no well known established procedure for the device to select a particular wireless host to establish a connection.
