An exercise apparatus is disclosed which simulates a stair climber, and which determines the amount of user exercise by the speed of rotation of a flywheel. The speed of the flywheel is controlled to maintain the desired speed of stair climbing by a friction belt engaging the flywheel. A rotary electrical motor is moved in one direction to tighten the belt on the flywheel and in the opposite direction to loosen the belt on the flywheel. A slack sensor determines whether the motor has been moved ...

This machine cuts and profiles large panels, as plywood, hardboard or similar materials, on one side to provide a large panel having a flat back surface and a profiled front surface, said front surface characterized by a plurality of longitudinally extending, side by side, slightly inclined flat surfaces separated by approximately perpendicular ledges or shoulders of narrow width, thereby imparting to the panel the appearance of lap siding when applied to the exterior wall of a building. This ma...

A reflective device is provided. The reflective device includes a reflective layer and a first region which reflects light to form an image that simulates a change in tooth color of at least a portion of a viewer's tooth.

A target simulates the coincident infrared and microwave signatures of a rce being tracked by a missile whose systems are undergoing test.

A device for converting a container into a figure to simulate an interactive game with a player, comprising a headboard in the shape of the head of the figure, a clip affixed to the headboard for attaching the headboard to the container, wherein a portion of the clip extends below the headboard where the clip connects to the container, a sensor mounted to the extending portion of the clip for generating an electrical signal in response to impact from an object projected by the game player, and f...

A footwear accessory for use with a shoe includes a stocking-like structure having a lower foot portion and an upper ankle portion wherein the lower foot portion is made of a porous hosiery material and the upper ankle portion is made of a material which simulates a boot leg. According to a presently preferred embodiment of the invention, the upper ankle portion is made of a stretchable material, may have a glossy or non-glossy appearance, may be a solid color or a print, may be provided with di...

A teething aid and toy includes upper and lower sheets of a transparent plastic material sealed together along their edges to form an internal cavity between the upper and lower sheets. The internal cavity is in the form of a number of cells each having its long axis in the same plane as the plane of the teething aid. The cells are connected by narrow necks set inwardly from the edge seals which define a single flow path. The cells are filled with a transparent liquid. Decorative drawings and/or...

A method of controlling a robot for testing of a motorcar by the simulated driving thereof, as on a chassis dynamometer. The robot is capable of detecting shifted operating quantities of actuators of the robot to correct the detected shifted quantities, whereby surely achieving operations of pedals and the like of the motorcar by the actuators. In the case where the actuators of the robot are shifted in position during a test driving of the motorcar, these positional shifts are automatically sen...

The present disclosure provides a method and apparatus for using frequency domain data, such as S-parameters, in a time-based simulator. S-parameters are either input to the simulator, or are empirically measured, at selected frequencies. Preferably, the selected frequencies are related to one another by a logarithmic scale, providing for determination of a system transfer function which is accurate across a very wide range of frequencies, from near zero hertz, to frequencies on the order of a h...

An electric breast pump utilizes an electric motor to drive a piston vacuum pump to draw a negative pressure or suction up to 250 mm Hg at a flexible collapsible breast cup. The suction cycles between the set maximum and atmospheric under the control of a magnetic valve that is opened and closed by a vacuum sensor. The valve opens and closes a bypass to atmosphere. The speed of the electric motor can be selectively varied to increase the frequency of the suction cycles, which can vary between 20...
