Abstract: The present invention relates to an enhanced design of electric hair brush wherein the improvement is achieved by incorporating an assembly whereby the wavy pattern commonly known as “waves” is achieved in a much faster time as well as a more defined wavy pattern because of the specifications incorporated specifically to achieve the desired enhanced results intended by use of the electric hairbrush which is designed for this specific purpose.

Abstract: In an elliptical step exercise apparatus distance traveled can be approximated by determining the portion of the ellipse traversed by a foot pedal where the user applies force to the pedal. This portion can be considered equivalent to the amount of foot travel on a treadmill and modified as a function of speed to simulate the gait of a user at various speeds so as to provide an approximation of the distance traveled by a user as if he were running on a treadmill. This process can be further modified for use with an elliptical exercise apparatus where the stride length can be changed such that the simulated distance will be increased with increased stride length.

Abstract: A screening support frame for use with modular screening systems. The frame comprises an attachment bar and a plurality of housings. Each attachment bar comprises one or more notches. Each housing is adapted to be lockingly received by a notch of an attachment bar. Also, each housing is adapted to releasably receive one or more legs from one or more screen panels.

Abstract: In an elliptical step exercise apparatus a dynamic link mechanism can be used to vary the stride length of the machine. A control system can also be used to vary stride length as a function of various exercise and operating parameters such as speed and direction as well as varying stride length as a part of a preprogrammed exercise routine such as a hill or interval training program. In addition the control system can use measurements of stride length to optimize operation of the apparatus.

Abstract: In an elliptical step exercise apparatus where stride length can be varied the various user programs can take advantage of this feature to provide for an enhanced workout. A control system can be used to implement a preprogrammed exercise routine such as a hill program where stride is shortened as the user goes up a simulated hill and lengthened as the user goes down the hill. In an interval training program, stride length can be increased and decreased at periodic intervals. In a cross training program, stride length can be decreased when the user is pedaling backwards and increased when the user is pedaling forwards.
