Abstract: A cylinder lock assembly includes a plug rotatable in a cylinder lock body. The plug includes chambers, each of which has a chamber depth axis. A plurality of thin, planar plug locking elements are received in the chambers. Each plug locking element has a key cut interface probe for interfacing with a key cut formed on a key. Each plug locking element is arranged to move along the chamber depth axis and does not rotate about the chamber depth axis. Each key cut interface probe has a predetermined orientation with respect to the chamber depth axis.

Abstract: A fingernail drill has a drill bit and a tip which is capable of drilling through a thickness of a fingernail. The tip extends longitudinally outwards from an abutment integrally formed with the drill bit, and the drill cannot drill past the abutment. The distance from the abutment to a distal end of the tip is such that the drill can drill through the thickness of the fingernail but cannot damage tissue under the fingernail. A kit is provided that includes the fingernail drill and a dispenser for dispensing a substance through a hole drilled by the fingernail drill.

Abstract: An article including a key comprising a key head that slides along a key shaft, said key head being affixable to said key shaft with a fastener.

Abstract: A key device including a shaft including a key-cut surface for forming inward key cuts thereon, a key head mounted on the shaft; and a fixed key pin protruding outwards from the key-cut surface.

Abstract: A padlock assembly includes two padlock halves fastened with at least one fastener, and a cylinder lock assembled with the padlock halves. A shackle has legs that are receivable in the padlock halves and lockable with the cylinder lock. The padlock halves are interlocked with the shackle such that even if the at least one fastener is removed, if the shackle is in a locked position with the cylinder lock, the two padlock halves cannot be separated from each other.

Abstract: A lock assembly including a cylinder lock including a plug and cam which are both rotatable about a longitudinal axis of the cylinder lock, and a latch and a rotatable deadbolt both operatively linked to the cam, wherein rotation of the cam about the longitudinal axis causes two actions: rotation of the deadbolt about a rotational axis different from the longitudinal axis to move the deadbolt to an unlocked position, and retraction of the latch to an unlatched position.

Abstract: A cylinder lock having a body and a modified cam, the cylinder lock being adapted for moving an external element arranged to engage the modified cam, so that the external element slides axially on the cylinder lock body. In a preferred embodiment, the inventive cylinder lock is designed to utilize a helical cam which engages a movable external element or slider, and this design is referred to as the HC cylinder lock. When operated by rotating the appropriate key within it, the movable external element can be moved in a linear fashion along the length of the HC cylinder lock thus converting rotational motion of the key to axial motion of the external element. The external element is arranged to engage an eccentric pin formed as part of a rotating bolt which rotates on an orthogonal axis to the cylinder plug in response to said sliding motion, for the function of locking or unlocking a device.
