The systems and methods described herein may help to provide for more convenient, efficient, and/or intuitive operation of a user-interface. An example computer-implemented method may involve: (i) providing a user-interface comprising an input region; (ii) receiving data indicating a touch input at the user-interface; (iii) determining an active-input-region setting based on (a) the touch input and (b) an active-input-region parameter; and (iv) defining an active input region on the user-interface based on at least the determined active-input-region setting, wherein the active input region is a portion of the input region.

A pneumatically operable fastener-driving tool and seal mechanism assembly, and a method of operating the same, comprises the use of a single, annular seal member, having a substantially V-shaped cross-sectional configuration, disposed within an annularly recessed portion of the fastener-driving tool piston in such a manner that the open region of the V-shaped annular seal member is disposed toward the relatively high-pressure upstream end portion of the fastener-driving tool cylinder, while, conversely, the closed region of the V-shaped annular seal member is disposed toward the relatively low-pressure downstream end portion of the pneumatic tool cylinder Accordingly, the relatively high-pressure air acts upon the radially outwardly flared lip portion of the annular seal member during a power stroke, while relatively low-pressure air acts upon the radially outwardly flared lip portion of the annular seal member during a return stroke, whereby only a single V-shaped annular seal member is required to achieve proper sealing performance characteristics throughout an operative cycle of the fastener-driving tool.

摘要:
An electronic system for integrating a user's moving image into a computer-generated pictorial environment, and allowing the user to interact with the environment and objects therein. The environment is rendered on a screen display in a manner that simulates three dimensions, including respect for occlusion relationships among the user and objects in the environment. The resulting image, which changes as the user gestures and interacts with the environment, is projected onto a large screen that the user faces. The environment includes a series of mobile entities, or "agents," which respond to one or more of the user's changing position, gestures and voice, exhibiting context-dependent behavior that appears semi-intelligent.

A follower mechanism of the bypass type comprises a follower body which is normally spring-biased in the forward direction so as to, in turn, normally bias a strip supply of nail-type fasteners in the forward direction toward a discharge path along which the leading one of the nail-type fasteners will he driven and discharged out from the fastener-driving tool. A follower claw is normally spring-biased, around the pivotal axis of a pivot pin mounted upon the follower body, to a position at which the follower claw can engage the trailing one of the nail-type fasteners so as to bias the supply strip of nail-type fasteners in the forward direction. A latch-hook is integrally provided upon the follower claw for engaging an undercut region of the fastener-driving tool magazine end cap in order to retain the entire follower mechanism at a rearwardly retracted position within the magazine assembly of the fastener-driving machine.

Attachments for a fastening tool are configured to position the fastening tool raceway for driving a fastener from the tool into a workpiece at a desired location. The attachments include work contact elements including a pair of surfaces for contact with two surfaces of the workpiece to properly position the tool raceway.

The invention involves a pressure fault device for indicating a threshold pressure or a threshold differential pressure. The present invention provides a cost effective way to determine where a pressure problem has occurred. The device includes a housing having at least one inlet aperture and an indicator aperture and having first and second bores in fluid communication respectively with one inlet aperture and the indicator aperture. The device further includes a magnetic piston which is biased in the first bore toward one inlet aperture and moveable a predetermined distance in another direction in the first bore in response to inlet threshold pressure. The device further includes a magnetic responder which is moveable toward the indicator aperture in the second bore in response to movement of the magnetic piston. The device further includes a latching plate in magnetic relationship to the magnetic responder when the piston moves the predetermined distance. An indicator is disposed in the second bore and partially extends through the indicator aperture. At a threshold pressure or differential pressure, the magnetic responder responds to movement of the magnetic piston and latches onto the latching plate, thrusting the indicator partially through the indicator aperture to indicate a threshold has been reached. The configuration of the magnetic piston and the magnetic responder prevents the magnetic responder from being dislodged from the latching plate, even when the threshold is removed and the magnetic piston returns to its initial position. The magnetic responder can be manually reset when the threshold pressure is removed.

Systems and methods for monitoring electromagnetic field power density are disclosed. The system includes a broadband antenna configured to convert a plurality of electromagnetic waves at a plurality of frequencies into a broadband signal. The system also includes a power adjustment system configured to passively selectively attenuate the broadband signal to provide a filtered output signal for a predetermined range of frequencies. The system further includes an output system configured provide an indicator to an end-user of the system if the filtered output signal exceeds a predetermined threshold level that characterizes a predetermined electromagnetic power density threshold.
