A step adjuster for an elliptical exercise device includes two assembly frames that are each pivotally connected with a sector gear and a movable sector disc for mutual movement. An eccentric portion of the sector gear and the movable sector disc are connected to crank blocks in slide grooves of the assembly frames by means of adjusting arms, and pedal cranks are respectively connected between the crank blocks and pedals. The sector gear has teeth engaging a worm gear of a hand crank, and moves to synchronously adjust the distance between the pedals and the connect rods.

A resistance control device for a training appliance includes a resist wheel fixed on the training appliance, and a magnet base adjustable in the distance between the resist wheel and having a plurality of magnets. A right end of the magnet base is pivotally connected to a fix base fixed with the training appliance, and a left end remaining free to move up and down and having a lateral rod. Further, an eccentric block is located at one side of the lateral rod, having a center shaft hole for fixing a shaft rotated by a drive source and a long curved slot for the lateral rod to fit in and move along. The distance between every point of the slot and the center shaft hole is decided by a calculation formula F=Ca.times.S all different. When the eccentric block is moved by the drive source, its moved distance causes the lateral rod also move for the related distance in the slot to rise or lower, altering the distance between the magnet base and the resist wheel so as to control resistance of the resist wheel against the magnet base. So this device is handy, saving time and labor, and adjusting resistance is precise.

Luggage having alarm device to protect against robbery, burglary and being inadvertently left behind comprises, inside the luggage, an alarm and shocker assembly that includes a siren and circuitry with a transformer to produce a high voltage. Bare electrical wires are spread around the inner wall of the luggage. A remote controller that is capable of dispatching a coded signal is used to activate the circuitry to produce a high voltage electric shock and/or sound an alarm to prevent the luggage from being carried away or stolen. The alarm assembly may further include a signal transmitting circuit and a receiving circuit and a buzzer may be added to the remote controller carried by the luggage owner. The effective distance can be preset for the response of a signal so that when the luggage is in a position beyond said preset distance, the alarm is triggered to warn that the luggage is being burglarized or is being inadvertently left behind.
