Abstract: An augmented reality interactive rehabilitation system includes an augmented reality eyewear device, a holding seat, a haptic module and sensing modules. The holding seat has a first recess and a second recess smaller in cross section than the first recess. The haptic module is removably placeable into the holding seat, and has a first end to be received in the first recess and a second end to be received in the second recess. The sensing modules are informationally connected to the augmented reality eyewear device and disposed in the holding seat to detect whether the haptic module is placed in a correct position.

Abstract: An optical lens of the present disclosure assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, an optical filter and a sensor. The optical lens also has an axis. The first lens element, the fourth lens element and the sixth lens element have negative power. The second lens element, the third lens element and the fifth lens element have positive power.

Abstract: A camera lens with a single optical axis includes a first lens having a positive refractive power, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, and an image sensor are arranged in sequence from an object side to an image side, where an axial distance between the third lens and the fourth lens is CT34, an axial distance between the fourth lens and the fifth lens is CT45, and the following condition is satisfied: 8.3<CT34/CT45<15.7.

Abstract: A filtrating module has a reservoir and a plurality of nozzles. The reservoir has an inlet opening, an outlet opening, a plurality of partitions, and a plurality of chambers. The chambers are respectively formed between each two adjacent ones of the partitions. Lower parts of the chambers communicate with each other but upper parts of the chambers are isolated from each other. The nozzles are respectively mounted under the inlet opening of the reservoir and in the upper parts of the chambers. Openings of the nozzles face downward and are inclined toward the next chamber, but the nozzle in the last chamber is inclined toward the outlet opening. A filtrating device includes the filtrating modules connected to each other. Therefore, the working fluid can be jetted downward and inclined to the liquid level of the working fluid, and thus contaminants in air can be dissolved in the working fluid.
