Abstract: A rivet structure includes a female rivet plate and a male rivet plate. The female rivet plate defines an elongated countersunk hole. A size of the countersunk hole increases from a first side of the female rivet plate to a second side of the female rivet plate. The male rivet plate includes a rivet including a shaft portion and two head portions. The shaft portion extends from the male rivet plate. The two head portions are respectively arranged on opposite sides of the shaft portion on a side of the shaft portion facing away from the male rivet plate. The two head portions extend through the countersunk hole from the first side of the female rivet plate to the second side of the female rivet plate. The two head portions are configured to be stamped by a stamping member to fill in the countersunk hole.

Abstract: An IC structure includes first and second gates, first and second source/drain regions, and an isolation region. The first and second gates each have a first portion extending along a first direction and a second portion extending along a second direction. The first source/drain regions are respectively on opposite sides of the first portion of the first gate. The second source/drain regions are respectively on opposite sides of the first portion of the second gate. The isolation region has a lower portion between a first one of the first source/drain regions and a first one of the second source/drain regions, and an upper portion partially overlapping with the second portion of first gate and the second portion of the second gate. A width of the lower portion is a less than a width of the upper portion.

Abstract: A reciprocating saw includes a casing, a clamping mechanism, a bracket, a first light-emitting piece, and a second light-emitting piece. The casing extends in a front-and-rear direction and forms an accommodation space. The clamping mechanism is disposed at least partially in the accommodation space and configured to clamp an operation accessory. The bracket is disposed at least partially on a front side of the clamping mechanism. The first light-emitting piece and the second light-emitting piece are disposed on a front side of the casing. The first light-emitting piece fits with the bracket and the operation accessory so that a cutting indicator line distributed in an extension direction of the operation accessory is formed. The second light-emitting piece fits with the bracket so that a cutting indicator region perpendicular to the cutting indicator line and extending in an up-and-down direction is formed.

Abstract: An IC structure includes first and second transistors, an isolation region and a first gate extension. The first transistor includes a first gate and first source/drain regions respectively on opposite sides of the first gate. The second transistor includes a second gate and second source/drain regions respectively on opposite sides of the second gate. The isolation region is laterally between the first and second transistors. A first one of the first source/drain regions has a first source/drain extension protruding from a first boundary of the isolation region, and a first one of the second source/drain regions has a second source/drain extension protruding from a second boundary of the isolation region. The first gate extension extends from the first gate to a position overlapping the isolation region.

Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing on an interior of the housing, and a bearing arranged between the spindle and the sleeve bushing and rotatably supporting the spindle. The bearing has an outer race. The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

Abstract: Provided is a method of compressing an occupancy map of a three-dimensional (3D) point cloud, and more specifically, a method of compressing an occupancy map of a point cloud in which an occupancy map image of a point cloud existing in a 3D space is compressed based on a compression quality or a patch-by-patch inspection method of the occupancy map image so that compression distortion is minimized when reconstructing the compressed occupancy map image so as to remarkably improve the quality of a reconstructed occupancy map image.

Abstract: A packaging structure is used for carrying at least one carried object. The packaging structure comprises a carrying unit and a covering member. The carrying unit includes a supporting plate, at least one first side plate connected to the edge of the supporting plate, and at least one combing member. The supporting plate has two opposite surfaces, and the first side plate is able to bend to one of the surfaces of the supporting plate, so that the carrying unit is able to present as an unfolded state or a folded state. The first side plate is stacked on the supporting plate when the carrying unit is in the folded state, and the combing member keeps the first side plate stacked on the supporting plate. The covering member is used for positioning the carried object on the carrying unit. The invention also provides a delivering device for clamping and positioning a plurality of the aforementioned packaging structures in an upright manner.

Abstract: A waterproof and air-permeable moist dressing which moisturizes and enhances color for aftercare of fresh tattoo. Therefore, the waterproof and air-permeable moist dressing can provide professional and medical repair, protection, isolation, and absorption of wound exudates and tattoo inks after tattooing to improve the aesthetical beauty of the tattoo.

Abstract: A first user associated with a structure (e.g., a home, a building, etc.) may authorize a second user to access the structure when the first user is not present. The second user may request to access the structure via a text message that includes an access code that was previously provided. The second user may be verified/authenticated based on the telephone number in which the text message was received, the access code, and/or an access schedule that indicates when the second user is authorized to access the structure. The second user may send a second text message indicating a desire to lock/unlock a structure entrance (e.g., a door) to the structure that contains a smart lock. Upon receiving the second text message, a service provider sends an instruction to the smart lock, causing the structure entrance to become locked/unlocked, and allowing the second user to access or secure the structure.
