  • Patent number: 12174449
    Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion, a fixed portion, a first driving assembly, and a plurality of second guiding members. The first movable portion is configured to connect an optical member. The optical member is used for adjusting a direction of a light from an incident direction to an outgoing direction. The first movable portion can move relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion. The second guiding members include a first ball, a second ball, and a third ball. The first ball, the second ball, and the third ball are disposed in a plane that is perpendicular to the incident direction.

  • Publication number: 20240297166
    Abstract: An integrated circuit package and a method of forming the same are provided. The method includes attaching an integrated circuit die to a first substrate. A dummy die is formed. The dummy die is attached to the first substrate adjacent the integrated circuit die. An encapsulant is formed over the first substrate and surrounding the dummy die and the integrated circuit die. The encapsulant, the dummy die and the integrated circuit die are planarized, a topmost surface of the encapsulant being substantially level with a topmost surface of the dummy die and a topmost surface of the integrated circuit die. An interior portion of the dummy die is removed. A remaining portion of the dummy die forms an annular structure.

  • Patent number: 12078863
    Abstract: An optical element driving mechanism is provided and includes a movable portion and a fixed portion. The movable portion includes a carrier for carrying an optical member with a first optical axis. The fixed portion has a top surface, a first side surface and a second side surface. The top surface extends in a direction that is parallel to the first optical axis. The first side surface and the second side surface extend in a direction that is not parallel to the first optical axis from the edge of the top surface and face different sides of the optical member. The shortest distance between the optical member and the first side surface is shorter than the shortest distance between the optical member and the second side surface. The optical element driving mechanism includes a noise-reducing structure configured to avoid a noise entering a photosensitive member.

  • 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: 12044844
    Abstract: An calibration kit includes a base, a combination of calibration parts, and a manipulation part. The combination of calibration parts is disposed on the base and includes a first calibration part and a second calibration part. The first calibration part has a first calibration surface. The second calibration part has a second calibration surface. The first calibration part and the second calibration part are relatively movable in a movement direction and are movable relative to the base. The manipulation part is movably or rotatably disposed on the base. The manipulation part is configured to be operable to drive the first calibration part and the second calibration part to move in the movement direction relative to the base, so that the combination of calibration parts forms a three-dimensional calibration surface configuration through the first calibration surface and the second calibration surface.
