Abstract: The present invention pertains to a wireless audio-video doorbell monitoring system, wherein a portable monitoring device administrates a doorbell device and detective devices. After initiation, the monitoring device calls other nearby devices to form a wireless network via a wireless broadcasting way, and then the monitoring device administrates each device to perform the doorbell or detection function. Via the automatic setup and simple operating interface, the present invention enables a general family to be free from a complex operational procedure. In the present invention, the detective device can sense the image and sound of the monitored regions, which is sent to a display panel and a speaker of the monitoring device without a time lag.

Abstract: A massaging chair includes a base frame supported on a wheeled support, a back support pivoted about a pivot on a mounting frame the at bottom of the base frame, a crank lever controlled lock device controlled to lock the back support in any of a series of sloping positions, elastic members connected between the back support and the mounting frame. The elastic members are stretched when the back support is released from the lock device and turned backward. A retractable supporting bar is fastened to the back support by a lock screw, and a back rest on the back support is vertically pivoted to the retractable supporting bar. A plurality of brackets are horizontally pivoted to the back rest at different elevations to hold rotating massaging wheels.

Abstract: An exercising machine including a base frame having a seat at the top, a scissor grip unit bilaterally pivotally connected to the base frame for exercising the hands through a scissor's action, a leg exercising unit coupled to the base frame at the front for exercising the legs, a back rest pivotally connected to the base frame at the back, a first pair of springy members bilaterally connected between the scissor grip unit and the base frame to produce a resisting force against the scissor's action of the scissor grip unit, and a second springy members bilaterally connected between the base frame and the back rest to give a resisting force against the backward movement of the back rest.

Abstract: An indoor gymnastic apparatus comprising an oscillating rod fastened to a base frame behind a seat to hold a rear extension rod, two handlebars connected to said seat at two opposite sides, a rocker seat made on said rear extension rod at one side to hold rotary cylindrical cushions, said rotary cylindrical cushions being each covered with a covering having raised portions over the outside surface thereof, a flat back cushion made on said rear extension rod at an opposite side, a front extension rod connected to said base frame to hold a pair of pedals for pedaling by the legs, wherein said rear extension rod follows the user's back to alternatively oscillate back and forth permitting said cylindrical cushions to massage the user's back.
