Abstract: An image conversion device includes: a lens module configured to allow passing of image light beams of an object, an optical waveguide element configured to transmit the image light beams to a light processing component, and an image sensor configured to convert the image light beams into digital image signals. By changing image capturing and image forming methods, higher image quality may be achieved and expanding flexibility may be maintained.

Abstract: An optical photographing lens 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 and a fifth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The second lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The third lens element has two surfaces being both aspheric. The fourth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof, wherein two surfaces thereof are aspheric. The fifth lens element has an image-side surface being convex in a paraxial region thereof, wherein two surfaces thereof are aspheric.

Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.

Abstract: A crushing apparatus includes a tank including a first aperture and a second aperture, a first blower around the first aperture, a grinder disposed within the tank, a separating device including a first hole connected to the second aperture, and a second hole, and a second blower disposed around the second hole.

Abstract: A fungus cultivation device includes at least one accommodating structure and a light-emitting diode module. The accommodating structure is disposed with a main body having an opening. The main body is internally disposed with an accommodating space for accommodating fungi strains and a light-permeable cover for covering the opening so as to seal the accommodating space. A plurality of light-emitting diodes of the light-emitting diode module irradiate the accommodating structure to supply a light source for the fungus inside the accommodating structure, thereby facilitating fungus growth.

Abstract: A cold/hot therapy device with temperature control includes a housing, a pump, a cooling chip, a cooling head, a cooling fin, and a bag. The pump, the cooling chip and the cooling head are fixedly arranged in the accommodating chamber of the housing. The cooling chip includes a cool-effecting surface and a cooling surface. The cooling head is adjacent to the cool-effecting surface, and includes a water inlet and a water outlet, where the water inlet communicates with the pump outlet. The cooling fin is fixedly arranged on the cooling surface of the cooling chip, and is positioned in the hollow passage of the housing. The bag includes an inlet tube and an outlet tube, where the inlet tube communicates with the water outlet of the cooling head, and the outlet tube communicates with the pump inlet. Accordingly, a cold or hot therapy function can be achieved.
