Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A blockchain-based member tracking system, communicatively connected to multiple web servers and multiple user devices, comprises an advertising database, multiple advertising modules, a primary member database, and a blockchain module. The advertising modules are configured to run on the web servers and are configured for displaying the advertising data. When the user device connects to the web server, the blockchain module generates a set of the preference tags and a set of the point data, and associates them with the corresponding member data of the user device. When the user device connects to the web server, the advertising module selects the advertising data based on the corresponding member data and the preference tags. The preference tags are a form of non-fungible token data.

Abstract: The present disclosure is relates to a conductive film and a manufacturing method thereof. The conductive film includes a base layer, a TPU complex layer, a conductive layer and a TPU surface layer. The TPU complex layer includes a TPU heat-resistant layer and a TPU melting layer. The TPU heat-resistant layer is disposed on the TPU melting layer, and the TPU melting layer is disposed on the base layer. The conductive layer includes a conductive circuit disposed on the TPU heat-resistant layer. The TPU surface layer is disposed on the conductive layer. Utilizing the TPU complex layer, the conductive layer does not contact directly with the base layer to avoid breaking the conductive line of the conductive layer when the base layer is pulled. Therefore, the lifetime of the conductive film can be increased.

Abstract: A foldable electronic device includes a first body having an end and a first inclined surface, a second body having a second inclined surface, and a hinge module. The end includes an accommodating area. A virtual shaft line exists between sides of the first inclined surface and the second inclined surface that are closest to each other. The second body rotates relative to the first body through the virtual shaft line. The hinge module includes a first bracket adjacent to the first inclined surface, connected to the first body, and located in the accommodating area, a second bracket adjacent to the second inclined surface and connected to the second body, and a third bracket including a first end and a second end. The first bracket is connected to the first end through a first torsion assembly. The second bracket is connected to the second end through a second torsion assembly.

Abstract: A mouthguard includes a mouthguard body and a film structure. The mouthguard body includes a front part, a rear part and a bottom part. A trench is defined by the front part, the rear part and the bottom part collaboratively. The film structure includes a first surface and a second surface. A marked pattern is printed on the second surface. The second surface of the film structure is attached on an outer surface of the front part of the mouthguard body while the mouthguard body is produced by an injection molding process, so that ink or pigment of the marked pattern is confined between the mouthguard body and the film structure without being exposed to outside.

Abstract: The present invention relates to a sterilization device for a dental appliance, which is primarily assembled from an upper cover, a holding body and a base, wherein a load supporting portion is formed at one end of the holding body, and the load supporting portion is fitted with a bacteria removal member. Moreover, a power supply device is disposed between the holding body and the base. Accordingly, an object to be sterilized is placed in the load supporting portion, and an electrical connection is effected with the bacteria removal member by means of the power supply device, thereby causing the bacteria removal member to release ozone (O3) or ultra violet rays to carry out sterilization of the object to be sterilized and achieve bacteria removal effectiveness.
