Abstract: An exercise device with adjustable damping force has a main tube, an operating rod assembly slidably mounted on the main tube, an upper hole seat mounted on an upper end of the main tube and having multiple upper damping holes, a lower hole seat mounted on a lower end of the main tube and having multiple lower damping holes, at least one upper blocking element mounted on the upper hole seat, and at least one lower blocking element mounted on the lower hole seat. By adjusting an area where each upper damping hole is covered and an area where each lower damping hole is covered, the damping force provided by the exercise device as described can be adjusted according to different needs of users, and the exercise device is easy to carry and is versatile.

Abstract: A portable water bottle has a bottle body, a lid assembly detachably connected to an upper end of the bottle body, a filter mounted in the lid assembly, a base detachably connected to a lower end of the bottle body, a temperature control module mounted in the base, and a power module mounted in the base. Liquid stored in the bottle body can be filtered by the filter when being poured out of the bottle body, so as to allow a user can drink the liquid directly and immediately. Moreover, the temperature control module is capable of heating or cooling down the liquid in the bottle body, so as to provide the user with the liquid having the temperature that is suitable for ambient it temperature or physical conditions of the user.

Abstract: Provided is a simplified input device, having a display module connected with a processing module. When the processing module receives a confirming command produced by an input module, the processing module loads a selected symbol. When the selected symbol is a typographical symbol, the processing module displays the selected symbol on a position of an input cursor. When the selected symbol is an input cursor moving symbol, the processing module moves the position of the input cursor corresponding to the selected symbol. Therefore, a user types letters, and moves the input cursor to a position of a wrong letter to input another letter for quickly correcting the wrong letter. Further, a connecting module receives typographical symbol setting data to update the language of the typographical symbols. The language is not limited by a manufacturer of the simplified input device and enhanced convenience in use is provided.

Abstract: The present invention discloses a battery tester having high precision, which has a casing having an input device and two detecting wires, a microprocessor, a variable loading unit and a battery power status detecting unit. The microprocessor builds a strategic decision process therein to determine a proper resistance of a load for a battery according to the battery capacity, initial voltage and detection requirements having 1/N CCA and loading time. When the resistance of the load is determined, the microprocessor adjusts a resistance of the variable loading unit equal to the resistance of the load for the battery. Therefore, the battery tester does not use the load with the fixed resistance to detect batteries with different capacities and has accurate detecting results.
