  • Publication number: 20250067954
    Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion used for connecting an optical element, a fixed portion, a first driving assembly used for driving the first movable portion to rotate relative to the fixed portion, and a guiding assembly having a first intermediate element. The first movable portion is movable relative to the fixed portion. The guiding assembly is used for applying a first stabilized force to the first movable portion for making the first intermediate element be in contact with the first movable portion or the fixed portion. The first movable portion is rotatable relative to the fixed portion.

  • Patent number: 12204163
    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.

  • Patent number: 12068092
    Abstract: A resistor structure includes a resistor body; and a first electrode structure disposed at and being in electric contact with a first end of the resistor body, and a second electrode structure disposed at and being in electric contact with a second end opposite to the first end of the resistor body. Each of the first electrode structure and the second electrode structure has at least one conductive protrusion. The at least one conductive protrusion of the first electrode structure and the at least one conductive protrusion of the second electrode structure both serve as voltage-sensing terminals for electric connection to an external voltage measurement device, or both serve as current-sensing terminals for electric connection to a current measurement device.

  • Patent number: 10438907
    Abstract: The present invention discloses a wireless package with a resilient connector for connecting a substrate to an antenna. The antenna is disposed directly on a top surface of a molding compound of the wireless package. The resilient connector has a lower terminal bonded to the substrate, a horizontal contact portion, and an oblique support portion integrally extending between the horizontal contact portion and the lower terminal. The horizontal contact portion has a flat top surface that is coplanar with the top surface of the molding compound and is in direct contact with the antenna such that the contact resistance distribution is concentrated and the production yield of the wireless package is improved.
