摘要:
The invention features a volumetric display system including an optical relay, a motor, a support structure coupled to the motor, a projection screen disposed on the support structure, and a projection optic. During operation, the projection optic receives a light beam from the optical relay and projects the light beam onto the projection screen. Also, the motor rotates the support structure, the projection screen, and the projection optic about a rotation axis.

A drink-thru lid for a drinking cup including an annular mounting portion for sealingly engaging the drinking cup, wherein the annular mounting portion includes a downwardly extending annular skirt. The lid further includes a tear-back section extending from the annular skirt to a hinge portion located in a medial portion of the lid. The tear-back section includes a raised protrusion extending outwardly from an upper surface of the lid. A recess is further formed in a medial portion of the lid on the opposite side of the hinge portion from the raised protrusion, wherein the tear-back section may be torn away from the lid on its sides and pivoted about the hinge portion until the raised protrusion is received within the recess for holding said pivotal flap open. The raised protrusion and the recess are shaped such that the raised protrusion is frictionally engaged by the end walls of the recess. The recess further includes a straw slot formed therein, wherein the straw slot is defined by two sloping side walls extending from an upper surface of the lid and converging together at a frangible juncture formed in the deepest portion of the recess.

An apparatus for performing a work operation on sheet material includes a plurality of drive wheels for driving the sheet material in cooperation with a plurality of pinch rollers along a feed path. Each of the drive wheels includes a drive surface having a plurality of primary teeth and a plurality of secondary teeth. Each primary tooth includes a top surface and a plurality of primary contact points to engage the sheet material. Each secondary tooth includes either a secondary contact line or a secondary contact point that come into contact with the sheet material to provide additional driving force and to prevent the sheet material from being perforated by the primary teeth. The primary teeth and the secondary teeth of the drive wheels engage the sheet material to advance the sheet material along the feed path. The drive surface of the drive wheels of the present invention minimizes slippage of the sheet material in the drive apparatus without damaging the sheet material.

A method for implementing variable rate optional security measures in a wireless communications network, the communications network having a plurality of nodes for communication with mobile subscribers, includes the following steps. A capacity constraint of at least one node of the network is first determined. A load list is dynamically maintained for each node as a function of the capacity constraint, the load list indicating any overload states of the nodes. Lastly, at least one optional security measure is performed on the network as a function of the load list, wherein the at least one optional security measure is selected from a plurality of optional security procedures. An apparatus for implementing variable rate optional security measures in a wireless communications network is also disclosed.

A snap-in device for connecting a window pane with a window regulator by using at least one pair of elastically expanding jaws wherein one of the jaws has at least one snap-in element in the form of a hook or pin pointing in the direction of the window pane and is associated with a hole in the pane. An insert guide device serves to expand the jaws when inserting the window pane into the snap-in device. In the engaged state of the window pane, the circumference of the snap-in element fills out the hole in the pane at least over a part of the width of the snap-in element.

Furan-3-carbohydroxamates of the formula ##STR1## where R.sup.1 is alkyl, unsubstituted or substituted cycloalkyl or unsubstituted or substituted phenyl, R.sup.2 is methyl or ethyl, R.sup.3 and R.sup.4 independently of one another are each hydrogen, bromine, chlorine, unsubstituted or substituted alkyl, or --CH.sub.2 --COOR.sup.5, where R.sup.5 is unsubstituted or substituted alkyl, and Me is divalent nickel or cobalt, stabilize plastics against the action of light, oxygen and heat. The compounds (I) have only slight intrinsic color.
摘要:
A seal including a generally annular casing, a generally annular sealing element that is configured to seal with a relatively movable member, and an insert coupled with the sealing element and the casing. The insert substantially maintains a relative position of at least a portion of the casing and at least a portion of the sealing element.

A system and method are disclosed for building virtual content from within a virtual environment using virtual tools to build and modify the virtual content.
摘要:
Disclosed is a method, implemented in a visualization device, to assist a user in placing 3D objects. In certain embodiments the method includes displaying, on a display area of the visualization device, to a user, various virtual 3D objects overlaid on a real-world view of a 3D physical space. The method can further include a holding function, in which a first object, of the various virtual 3D objects, is displayed on the display area so that it appears to move through the 3D physical space in response to input from the user, which may be merely a change in the user's gaze direction. A second object is then identified as a target object for a snap function, based on the detected gaze of the user, the snap function being an operation that causes the first object to move to a location on a surface of the target object.

A reversible bracelet includes a series of open insert or panel holding frames, wherein each frame holds a two sided panel therein with each side of the panel including an ornamental design. Each frame may be rubber or silicon or similar materials and maybe i) generally “C” shaped in cross section to receive and retain one panel therein, or ii) includes a retaining bead received within a matching groove in the associated panel to receive and retain the panel therein. The panels may be press fit into the frame. Each frame/panel may be pivoted relative to the adjacent frame/panel to provide selective reversibility to the bracelet or the bracelet may be flipped in its entirety. The panels may be formed of two separate facing halves coupled together and may be designed by the user's themselves in an on-line panel creation system.
