Abstract: An exercise balance trainer includes a hard board and a resilient ball body connected to the board. The ball body has a first curved wall with a first rim, a second curved wall with a second rim connected fixedly to the first rim so as to define an air-receiving chamber between the first and second curved walls, and an annular flange connected to the board and a junction of the first and second rims. The first and second rims have the same diameter. The first curved wall has a maximum height that is not greater than one-half of the diameter of the first rim. The second curved wall has a maximum height that is not greater than one-third of the diameter of the second rim.

Abstract: In a device for aerobic exercise, a resilient bladder body has a bottom wall disposed on a base frame, a curved surrounding wall connected to the bottom wall so as to define a fluid-receiving space therebetween, and a surrounding flange extending downwardly from the curved surrounding wall and disposed to surround the base frame. The bladder body defines a first axis that passes through a center of the bottom wall and along which the bottom wall has a width, and a second axis which passes through the center of the bottom wall and a top wall portion of the surrounding wall, which is transverse to the first axis and along which the curved surrounding wall has a maximum height less than the width of the bottom wall. The top wall portion has a rigidity greater than that of the surrounding wall portion and less than that of the bottom wall.

Abstract: A brightness difference ornamental screen with multi-function includes an ornamental layer, a light display member and a control device for controlling the light display member. The ornamental layer may be set up nearby the light display member. The light display member is connected to the control device. The ornamental layer may be a translucent pattern. The light display member is a light source. There are contents to be displayed behind the ornamental layer. The control device may be a key or a touch switch or an electronic switch to make the light source turn on/off. The ornamental screen has functions as an ornament, as well as displays contents behind the ornamental layer. The ornamental screen has dual-purpose and may utilize space sufficiently, while its structure is simple and purpose is widespread.

Abstract: A compliant body-pressing exerciser, which may constitute an inflatable, compliant structure, is adapted to be mounted to a seat or rigid frame, and includes a bowl-shaped lower member and a dome-shaped upper member formed respectively with upper and lower surrounding edge portions that engage each other and adapted to contact the ground and compliantly press against a user's body. A height of the upper member is larger than that of the lower member. Exercising assemblies that comprise elastic or bungee cords may be coupled to the frame.

Abstract: A compliant body-pressing exerciser is adapted to be detachably coupled to a seat frame, and includes a bowl-shaped lower member and a dome-shaped upper member formed respectively with upper and lower surrounding edge portions that engage each other and adapted to contact the ground and compliantly press against a user's body. A height of the upper member is larger than that of the lower member. A shortest one of radial distances measured from a central point to the lower surrounding edge portion is not less than the height of the upper member so as to lower the gravity center of the exerciser.

Abstract: An Adjustable Segmented Dual Function Mirror with video display (ASDFM) suitable for providing alternatively or simultaneously both a conventional reflected image and a video image under a wide range of ambient lighting condition is disclosed. The ASDFM comprises a two-dimensional connection of traditional mirror segments and dual function mirror segments. Each dual function mirror segment can be rotationally and adjustably connected to the rest of the ASDFM to achieve an optimal visually relevant image-to-ambient contrast for viewing. Alternatively, a position adjustable variable transmissivity screen, a controllable variable transmissivity film or a controllable variable reflectivity film can be included in a dual function mirror segment that is rigidly connected to the rest of the ASDFM for the same purpose. Numerous mechanical, fluid dynamical and electrical implementations are described.

Abstract: An adjustable dual function mirror includes a plate including a smooth surface and a video display device disposed in spaced relationship to the plate, the plate and video display device being rotatable about at least one axis.

Abstract: The present invention discloses a two way, rear view mirror suitable for providing alternatively or simultaneously both a conventional reflected image and a video image. A preferred two way mirror of the invention comprises a flat transparent plate coated with or glued with a reflective film mounted within a casing which provides supports for the mirror and a mounting space for at least one video display monitor with a built-in light source mounted in said casing and positioned directly behind said reflective film to receive and display image received from a variety of information sources.

Abstract: An improved network timer for use in a network node, preferably a reliable mode network employing IPX/SPX data packets on workstations or computer. A method and apparatus is disclosed for use by a workstation node whereby a plurality of data packet timers may be supported and set, triggered and deleted in a maximum of K operations or time increments, where K is a constant and not a function of N.
