A head-mounted display device includes: a light guide prism in a polyhedron shape having a first optical surface facing a wearer side in a mounted state, and a third and a fourth optical surfaces each forming an acute interior angle with the first optical surface; a video display portion for emitting video light toward an incident portion on the first optical surface; and an eyepiece lens cemented to or integrally formed with an emitting portion on the first optical surface. Video light incident on the incident portion on the first optical surface is reflected by the third optical surface, the first optical surface and the fourth optical surface, and is emitted toward a pupil direction of the wearer on an optical axis of the eyepiece lens. The incident portion and the reflecting portion overlap each other in part while the emitting portion avoids overlapping with the reflecting portion.

A brassiere includes a pair of shoulder straps and a pair of cup members located generally below the shoulder straps. Each of the cup members includes an inner contact layer substantially completely covering the breast of a wearer, and an outer compression layer slidably disposed in covering relation to the inner contact layer. An adjustment and securing assembly is disposed between each outer compression layer and its corresponding shoulder strap. The adjustment and securing assembly, which may be provided as a hook-and loop fastener system, is adapted and constructed to adjustably secure the outer compression layer to the shoulder strap. Attachment of the outer compression layers to the shoulder straps lifts and compresses the breasts of the wearer to reduce the potential for inertial movement of the breasts both outwardly and downwardly.

A brassiere is dislosed including a pair of shoulder straps. A pair of cup members is located generally below the shoulder straps, each of the cups including an inner contact layer covering the breast of a wearer and a unitary outer compression layer slidably disposed in covering relation to the inner contact layer. The outer compression layer is substantially coextensive with the inner contact layer. An adjustment assembly is disposed between each outer compression layer and its corresponding shoulder strap. A securing assembly is adapted and constructed to adjustably secure the outer compression layer to the shoulder strap. Attachment of the outer compression layers to the shoulder straps lifts and compresses the breasts of the wearer to reduce the potential for inertial movement of the breasts. A method of reducing inertial movement a brassiere wearer's breasts is also disclosed. In a brassiere including a pair of cup members and a pair of shoulder straps, a downward force is exerted on the wearer's breasts sufficient to reduce upward inertial movement of the wearer's breasts. An upward force is simultaneously exerted over the entire frontal area of the wearer's breasts sufficient to reduce downward inertial movement of the wearer's breasts.

A stool includes a collapsible frame, a triangular seat and a back. The frame includes a bottom hub with three telescopingly adjustable legs and enlarged feet. A top hub is rotatably coupled to the bottom hub for 360 degree rotation, and includes three seat-supporting arms that extend from the top hub, and a pair of uprights that extend from two of the arms. The seat hook-attaches to loops on ends of the arms, and the back extends between the uprights. The legs and arms are pivoted to their respective hubs, but the pivots are slightly frictional so that the arms and legs remain in adjusted positions, with stops on the hubs stopping the legs and arms in their upwardly-pivoted use positions. The frictional pivots include lubricious plastic that facilitates quiet unfolding of the stool, which is important when hunting.

A cloth diaper is fitted, washable and reusable, and highly effective in reducing or preventing leaks. The diaper comprises fabric preferably on both the outermost surface and the inner most surface that is stretchable, soft, and has hydrophilic and wicking properties. The diaper comprises an inner absorbent layer(s) between said hydrophilic and wicking fabric layers. A preferred continuously-adjustable fastening system may be used to adapt the diaper to fit a wide range of sizes of infants and toddlers, for example, from birth up to four years old. The fastening system allows a large amount of the front side of the diaper to be folded inside the diaper, significantly changing the overall size of the diaper to accommodate small infants. Even with the large folded-in flap, soft, wicking fabric is maintained against the child's skin, and the fastener system portion that is also folded inward does not interfere with absorbency. The preferred “V-shaped” fastener extends far down on the front side of the diaper, most of the way to the “crotch” area of the diaper, and also has wings/extensions from the top ends of the arms of the “V”, thus, allowing fastening of the diaper all along the length of each of the arms of the “V” and also out along the transverse length of the wing/extensions.

An object of the present invention is to inhibit intergranular corrosion of a lead alloy by grain refining, and to prolong the life and improve the reliability of a lead battery using the alloy for a positive current collector in the battery. The intergranular corrosion of the lead alloy is inhibited by adding Sr to a Pb—Sn alloy to refine a cast structure and the recrystallized structure of a rolled material, and the hardness is improved by further adding Ca, Ba and Te. In addition, the rolled sheet of the lead alloy is used in the positive current collector of the lead storage battery.

The invention discloses a driving-and-braking-optimal-switching electric-automobile adaptive cruise control method. The driving-and-braking-optimal-switching electric-automobile adaptive cruise control method includes the following steps that ideal driving-and-braking torque and the driving-and-braking switching rule are calculated through an upper controller; the ideal driving-and-braking torque is distributed on four wheels through a lower controller. According to the driving-and-braking-optimal-switching electric-automobile adaptive cruise control method, the driving-and-braking-optimal-switching adaptive cruise control strategy is designed and converted into a real-time mixed-integer nonlinear programming proposition through the upper controller according to the current road environment and the driving requirements, the proposition is solved through the double-nesting solving algorithm based on the modified genetic algorithm, and the driving-and-braking switching rule and the corresponding driving/braking controlling torque are obtained. The torque is distributed by the lower controller to hub motors through vertical loads according to the ideal driving-and-braking torque calculated by the upper controller to allow wheels to harmoniously run. The number of actions of a driving actuator and a braking actuator is reduced, and the wheels tend to be in the best working state accordingly.
