  • Patent number: 7129818
    Abstract: In a method for determining whether a person is potentially unavailable for communication, sensors are provided at a location to obtain information regarding a state of availability for communication of a first person at the location. The information regarding potential unavailability of the first person for communication is presented to a second person. A system for determining whether a person is potentially unavailable for communication includes a data acquisition module that has sensor receiving ports and is configured to transmit signal data from the sensors over a network. An inferencing engine is configured to receive the signal data from the sensors over the network and to use the signal data to reach an inference regarding a person's presence and an inference regarding the person's potential unavailability for communication. A presence service presents the inferences to other persons over the network before such other persons attempt to communicate with the person.

  • Patent number: 6990546
    Abstract: A portable computer can be “hot” docked to one or more expansion devices, such as a drive wedge and a port replicator. As such, the expansion devices can be connected to and disconnected from the portable computer while portable computer is powered on and fully operational. The portable computer includes control logic that detects when an expansion device is connected to or disconnected from the portable computer and asserts an SMI or equivalent interrupt signal to the computer's CPU to initiate a sequence of events by which the computer determines whether an expansion device has been connected or disconnected. If the CPU determines that the expansion device has been connected to the computer, the CPU appropriately reconfigures itself to communicate with the expansion device. If the expansion device is disconnected, the CPU also appropriately reconfigures itself to preclude communications with the disconnected device.

  • Patent number: 6934737
    Abstract: One embodiment of the present invention provides a shared window into which a remote user can input commands from a remote computer system subject to access control. The system operates by receiving a command from the remote user on the remote computer system, wherein the command is directed toward the local computer system in order to operate the local computer system. If the command passes a filtering process, the system executes the command to a local operating system so that the command can operate on the local computer system. The system also displays the command on the shared window on the local computer system so that a local user can view the command. The system additionally allows the command to be displayed on a remote copy of the shared window on the remote computer system, so that the remote user can view the command. In one embodiment of the present invention, if the shared window is in an approval mode, the filtering process involves allowing the local user to approve the command.

  • Patent number: 6908148
    Abstract: A collapsible sunshade shelter encloses a child safety seat. A pair of side walls each have a side shade fabric attached to a frame perimeter and a top shade fabric between the frames. The frames each comprise a flexible tension member normally in a frame configuration but adapted for collapsing by twisting and folding into concentric smaller frames. A tie pulls in the front bottom edges while stretching out the top edges of the frames. Inwardly angled back extensions of the side frames are pushed inward by the vehicle seatback to push out the top front frame edges. A top frame may be inserted between the side panels to maintain the panels apart. A front shade panel may be attached by zippers or hook and loop fasteners. Loop-type fabric around the frames receive hook patches from the front panel to hold it open in any desired position.

  • Patent number: 6731308
    Abstract: The present invention provides methods and systems for providing distributed parties reciprocal information regarding each other's activities. For example, the method of the invention provides selected information regarding the availability of an intended recipient to engage in a communication session with an initiator, and reciprocally informs the intended recipient of the initiator's access to such information. Further, the method of the invention can provide a signal to an intended recipient to indicate an initiator's intention to establish a communication session. Further, the method of the invention provides a signal to each party to indicate whether a communication session has been established. In another aspect, the invention provides a method for informing the participants in a communication session of a party's intention to terminate its participation in the session.

  • Patent number: 6716823
    Abstract: Disclosed and claimed are methods of non-invasive genetic immunization in an animal and/or methods of inducing a systemic immune or therapeutic response in an animal, products therefrom and uses for the methods and products therefrom. The methods can include contacting skin of the animal with a vector in an amount effective to induce the systemic immune or therapeutic response in the animal. The vector can include and express an exogenous nucleic acid molecule encoding an epitope or gene product of interest. The systemic immune response can be to or from the epitope or gene product. The nucleic acid molecule can encode an epitope of interest and/or an antigen of interest and/or a nucleic acid molecule that stimulates and/or modulates an immunological response and/or stimulates and/or modulates expression, e.g., transcription and/or translation, such as transcription and/or translation of an endogenous and/or exogenous nucleic acid molecule; e.g.

  • Publication number: 20040039630
    Abstract: A system and method effectuates scheduling and initiating contact between people without sensitivity to time issues, and can ascertain when is the best time and most promising communications medium to use to reach another person to schedule time together or by which to initiate contact. A system and method also ascertains a person's expected activities. This provides effective and accurate information on general patterns that can be timely promulgated to all group members to help initiate contact without requiring simultaneous virtual presence to be effective. A system and method ascertain a person's activities, location, and corresponding rhythms and allows corresponding inferences regarding coordination, communication, and contact. An embodiment of the present invention thus provides to distributed co-workers some of the cues and advantages enjoyed in more traditional workplaces which facilitate such interaction therein.

  • Patent number: 6686933
    Abstract: A lightweight indicator provides an indication of divergence of views for a collaboratively used user interface element. The lightweight indicator identifies the magnitude of the divergence of views. The user interface may be, for example, a graphical widget, such as a mouse cursor or a scrollbar. The indicator is “lightweight” in that the indicator only subtly modifies the appearance of the user interface element. The indicator is also “lightweight” in that it provides an indication without incurring significant computational or memory overhead.

    Abstract: The present invention provides a method and apparatus for accessing related computer objects. In one embodiment, computer objects related to a user's current task by a metric are listed. In another embodiment, other users related to a user's current task by a metric are listed. In one embodiment, the metric used to determine whether a user is related to a computer object determines whether the user accessed the computer object. In another embodiment, the metric used to determine whether a user is related to a computer object determines whether the user is referenced in the computer object. In other embodiments, the metric used to determine whether a user is related to a computer object involves other measures of relatedness. In one embodiment, the metric used to determine whether a computer object is related to another computer object determines whether the computer objects have a related user in common.
