Abstract: A personal display device for displaying virtual images to a wearer. The personal display device includes a frame having a right temple section, a left temple section, a right rear section, a left rear section, a right eye see-through section, and a left eye see-through section; a projection display device connected to the frame for projecting an image to the wearer; at least one waveguide stack module connected to the frame for propagating image-bearing light beams along a length of the at least one waveguide stack module, the at least one waveguide stack module being configured to receive the image from the projection display device and detected touch motions of the wearer sensed by the touchpad including sensing directions of the touch motions of the wearer.

Abstract: A folding knife assembly includes a blade system which is disposable between an open configuration and a closed configuration using a single hand. The blade system includes a fixed blade member and a movable blade member, wherein the fixed blade member and moveable blade member are cooperatively structured to operatively engage one another when the blade system is disposed in an open configuration. The folding knife assembly also includes a positioning system structured to facilitate disposition of the blade system between an open configuration and a closed configuration. A locking system is provided and is structured to operatively engage at least a portion of the positioning system to releasably secure the blade system in the open configuration, and to operatively disengage the positioning system to permit disposition of the blade system into a closed configuration.

Abstract: A screwless bow or rifle support for the attachment to objects in a hunting environment such as trees without the need for screws or other bore holes.

Abstract: A folding knife assembly includes a blade system which is disposable between an open configuration and a closed configuration using a single hand. The blade system includes a fixed blade portion and a movable blade portion, wherein the fixed blade portion and moveable blade portion are cooperatively structured to engage one another in an interlocked configuration when the blade system is disposed in an open configuration. The folding knife assembly also includes a positioning assembly structured to facilitate disposition of the blade system between an open configuration and a closed configuration. A locking assembly is provided and is structured to operatively engage at least a portion of the positioning assembly to releasably secure the blade system in the open configuration, and to operatively disengage the positioning assembly to permit disposition of the blade system into a closed configuration.

Abstract: In some implementations, a method for reducing material loss includes adding, to a downhole fluid circulated through a drill string, encapsulants encapsulating one or more activators. One or more parameters in a wellbore associated with a fault in operating conditions are determined. One or more energy waves in the downhole fluid configured to release the one or more activators from the encapsulants are emitted.

Abstract: One embodiment of folding knife using a mechanical linear slide action blade deployment system housed in a predetermined shaped cavity (28). Said slide action blade deployment system is comprised of a sliding member (1) made of a heat treated steel alloy and coated for low friction and high wear. Sliding member (1) is actuated by short linear thumb pressure on a sloped tab (5) located on top handle (2), thus transmitting sliding force from sliding member leading edge to blade opening pin (13) made of heat treated and coated for low friction and high wear attached to blade (3) axle at a predetermined location. This action causes blade top rotate out of handle to the locked open position. Thumb actuated sloped tab on top handle returns to starting position via a sloped tab return spring (16) housed in a cavity between inside top handle and top liner (11).

Abstract: A category topic includes a data incarnation and a sensory representation. The appearance of the sensory representation is adjusted upon changes to the content of the data incarnation. In a described implementation, a title of the category topic is used to create the sensory representation as displayed on a user interface (UI). In another described implementation, the data incarnation includes a source definition and a keyword definition that jointly specify information that is to be included in the content. In yet another described implementation, at least part of a category topic may be shared with a destination user.

Abstract: Methods and compositions for use in subterranean operations, and more particularly, additives comprising one or more silicates used to treat tar resident in a well bore, and methods of use, are provided. In one embodiment, the method comprises a method of treating tar resident in a well bore comprising providing a tar-treating additive comprising one or more silicates introducing the tar-treating additive into the well bore; and allowing the tar-treating additive to react with the tar resident in the well bore so as to at least partially reduce the adhesiveness of the tar.
