  • Patent number: 6665741
    Abstract: A portable computer includes a removable I/O device, where the removable I/O device is separate from a built-in cursor control device of the computer so that the computer stays functional without the removable I/O device. Consequently, if the presenter wants to return to the computer and use it directly, he does not have to place the removable I/O device back in the computer, which may disrupt the operating mode. Alternatively, the removable I/O device or both a receiver system and the removable I/O device may be designed to fit in one of PC card slots of the computer when not in use. This alternative enables the presenter to use an existing computer for presentations by simply plugging the receiver system and/or the removable I/O device in one of the computer's existing slots. The computer may further provide for automatic configuration of external video output or internal display modes once the removable I/O device is detached from the computer.

  • Patent number: 6643721
    Abstract: A computer user interface and method for its operation are disclosed. The interface uses a new architecture that allows it to adapt readily to the type of input device being used to operate the computer. The look and feel of the interface depends on which input device is selected as primary. Thus, when mouse/keyboard is the primary input device, the interface-controllable elements such as scrollbars, buttons, icons, menus, lists, and dialog boxes may appear as with a conventional GUI. When a different physical input device is primary, such as pen or speech recognition, the look and feel of these elements can change to be more appropriate for that device. This change is virtually transparent to the applications utilizing the user interface.

  • Patent number: 6539441
    Abstract: The present invention combines features of an executable process with the need for multiple application programs to share a single input device. The present invention provides an executable program implemented as a process that allows multiple applications to communicate with a single input device. This is achieved by loading the input device control executable program as a process. The executable program is a server thus allowing multiple application programs to interface with the same input device. The multi-instance input device control (MIIDC) executable program responds to each application program request as if the input device is open for the calling application program. Each application program is thus enabled to communicate with the input device instance without interrupting the operation of other application programs communicating with the input device. The input device instance keeps track of all the connections to it and multiplexes and resolves conflicting requests.

  • Publication number: 20020023183
    Abstract: A pointing device has a controllable selector for sending a version compatible signal and a newer functionality signal to a computer terminal. The pointing device has an operating unit which produces a signal which can be passed directly to the computer terminal, or can be modified with a new functionality, and then passed to the computer terminal. A controller in the pointing device monitors a protocol signal line to determine whether a version compatible signal or a new functionality signal is called for. The controller can activate a new functionality circuit and the selector to send the appropriate signal to the computer terminal. The controller can also monitor the protocol signal line in a power-on state, and execute a procedure to determine the functionality requested by the protocol signal line.

    Abstract: An integrated processing box performs processing commonly to a plurality of input devices, a plurality of output devices, or a plurality of storage devices. For example, the integrated processing box performs noise reduction processing on data received from an input device or a storage device or data supplied to an output device or the storage device. The integrated processing box also performs processing, for example, temporal/spatial processing or grayscale processing, variably to each type of input device, each type of output device, or each type of storage device. Accordingly, if the input device is, for example, a video camera, the video camera is formed only by a CCD, a sample-and-hold circuit for sampling and holding the output from the CCD, an AGC circuit for adjusting the gain of the output from the sample-and-hold circuit, and an A/D conversion circuit for converting the analog output of the AGC circuit into a digital output.

  • Patent number: 6317119
    Abstract: A method for determining a position of a joystick in data communication with a processor and having an initial state that includes steps of varying the initial state in response to a signal from the processor; returning the joystick to the initial state after a duration of time, with the duration of time being dependent upon the position amongst a plurality of positions. A plurality of poll operations of the joystick are executed to sense the returning step. Each of the polling operations results in a data signal being transferred from the joystick indicating the state of the same, with consecutive poll operations being separated by a predetermined segment of time, defining a first interval and consecutive data signals operations being separated by a time period, defining a second interval. The second interval is increased to be greater than the first interval, the duration of time is measured by determining a number of data signals received by the processor between the varying step and the returning step.

  • Patent number: 6307548
    Abstract: A reduced keyboard disambiguating system. The keyboard has twelve to sixteen keys, nine of them labeled with numerous letters and other symbols, and those nine plus one more are associated each with one of the ten digits. Textual entry keystrokes are ambiguous. The user strikes a delimiting “Select” key, or a key with an unambiguous character interpretation, at the end of each word, delimiting a keystroke sequence that could match any of a plurality of words associated with the same keystroke sequence. Each input keystroke sequence is processed with a complete vocabulary, and words which match the sequence of keystrokes are presented to the user in order of decreasing frequency of use. The vocabulary is stored in a special format that supports significant data compression without requiring additional processing. In addition, stems of longer words whose initial letters match the sequence of keystrokes are also presented to the user in order of decreasing frequency of use.

  • Patent number: 6304921
    Abstract: A microcontroller (12) provides the address bit and device data start bits for the first peripheral device (PD) in a string of PDs (20-24 or 30-34). Each PD includes a string of flipflops (72-86). If the complete address matches, then the first PD (20) shifts out the device data start bits for the next PD (22) in that string. The address bit for the next PD is provided by the pull-up or pull-down device (52) hard-wired on the SI of the next PD. The device data start bits for the next PD are provided by right-most flipflops of the previous PD. If the address bit and device data start bits match the contents of the device registers of next PD, then that next PD enables SYSCLK to shift out the contents of flipflops.

  • Patent number: 6282659
    Abstract: Information systems which provide access over a variety of devices (e.g. telephones, automated banking machines, computers) typically require that passcodes be numeric to allow entry on all device types. Alphabetic characters are associated with the numeric digits on both telephones and automated banking machines, allowing users to use mnemonic words to remember their numeric passcodes. Computer terminals do not have this association, creating user difficulties. The invention translates text entry on a computer keyboard into the equivalent numeric digits according to an appropriate mapping.
