High security combination padlock with locking bar

By forming a combination padlock from heavy duty metal throughout with an enlarged, heavy duty locking bar or shackle being employed having a tamper-proof holding cavity for the terminating, locking end of the locking bar, an effective, easily produced, high security padlock is achieved which employs a combination system for fully operating the padlock. In addition, the combination padlock of the present invention incorporates tumbler or clutch wheel constructions which cooperate with the rotating dials to virtually eliminate any possibility that an unauthorized person would be capable of gaining access to the padlock by known combination lock picking techniques by forming each tumbler or clutch wheel with a plurality of radially extending fins formed thereon, with each of the fins being arcuately spaced from the adjacent fin in a non-symmetrical pattern. Furthermore, the padlock of the present invention incorporates a unique combination setting and re-setting assembly which employs a slider shaft incorporating a radially extending post, which must pass through a key-hold slot formed in the body or housing of the padlock for activating the combination setting or re-setting mode, and cooperates with a set screw member threadedly engaged with the housing or body of the padlock which controls the axial movement of the shaft.

Autostereoscopic display device

ActiveUS20110164036A1Reduction in intensity modulation depthReduce unevennessSteroscopic systems3D-image renderingImage formationDisplay device
An autostereoscopic display device comprising a view forming module in registration with an image forming means. The image forming means has an orthogonal array of display pixels spatially defined by an opaque matrix. The view forming module provides at least two optical functions, namely a view forming function and a brightness non-uniformity reducing function. The view forming function modifies the direction of outputs of the display pixels such that the outputs of groups of the display pixels are projected in respective different directions as a plurality of views. The view forming function is provided by an array of parallel lenticular lenses arranged across the view forming module and having a first pitch. The brightness non-uniformity reducing function spreads the outputs of the display pixels such that brightness non-uniformities caused by imaging of the opaque matrix are reduced. The brightness non-uniformity reducing function defines a second pitch across the view forming module less than the first pitch, and further defines an effective spreading angle in a plane perpendicular to axes of the view forming elements substantially equal to or less than the angle between adjacent views projected by the view forming function. The brightness non-uniformity reducing function is provided by an array of lenses or a diffuser. In the case of an array of lenses, these lenses may be integrated with the lenticular lenses providing the view forming function in the form of lenses having a polygonal cross section.
