Abstract: A fitness device including an exercise assembly is provided. The exercise assembly includes a first rotary motor and a linear motor. A user applies an exerted force to operate the exercise assembly according to different movement trajectories of multiple training movements, such that the exercise assembly is driven by the linear motor to move linearly along an axis, and is driven by the first rotary motor to rotate. The first rotary motor outputs a rotational resistive force in response to the rotation of the exercise assembly, the linear motor outputs a linear resistive force in response to the movement of the exercise assembly, and the rotational resistive force and the linear resistive force are combined to form an integrated resistive force. The exerted force is greater than the integrated resistive force.

Abstract: A smart ring includes an antenna chip and a metal ring used as an antenna, and the antenna chip is electrically connected to the metal ring to form an antenna circuit. The metal body of the smart ring is designed as a composition structure of the antenna circuit, that is, the antenna is integrated into the metal ring, the space for accommodating the antennas and the cost for additional physical antennas are saved, and the design flexibility and the competitiveness of the product are improved. Nickel-zinc ferrite is unnecessary, which can reduce the cost. The ring can keep the radiation characteristic of the circular antenna that is not susceptible to the interference from human body. The metal body of the ring is a metal structure, which can fulfill both of strength requirement and texture requirement of the structure, and at the same time has good antenna characteristics.

Abstract: A wireless transmission system comprises an antenna component, a wireless module including a processing unit and a power controlling unit, a tuner connected between the antenna component and the wireless module, and a sensor connected to the wireless module. The tuner is configured to adjust an output bad of the power controlling unit according to a received signal strength indication of the wireless transmission system being greater than a predetermined threshold value, such that multiple different load values are provided for the power controlling unit. The sensor is configured to detect and record a current consumption value corresponding to each load value. In response to the wireless module emitting signals via the antenna component, the processing unit selects the load value corresponding to the lowest of the current consumption values and applies the selected load value to the output load of the power controlling unit.

Abstract: An intelligent pillbox with volume detection includes an open-close structure, a first structure, an air pressure sensing module and a processor. The first structure is movably configured on the open-close structure, and moves in and out of the containing space of the open-close structure to generate a constant volume difference. The air pressure sensing module is configured in the containing space for measuring the multiple air pressure values in the airtight space. The intelligent pillbox with volume detection calculates the medicine volume by the constant volume differences and the air pressure change when the patient takes out the medicine from the medicine box. It not only can avoid the patient taking wrong medicine, but also can detect the number of remaining medicine and remind the patient to replenish the medicine in the medicine box.
