A mechanism including a first pair of races having a first pair of raceways and a first rolling element operable to roll between the first pair of raceways, wherein at least one of the first pair of raceways has a substantially variable curvature along at least a portion of a path of the first rolling element. A program product that determines a solution by adjusting the curvature of a first pair of raceways on opposite sides of a rolling element, at least one of the first pair of raceways having a substantially variable curvature along the contact points in the direction of the corresponding range of motion for the rolling element.

A cork screw bottle lock is used to secure a cork within a bottle and to facilitate removal of the cork from the bottle using a screw on/off mechanism. A cork screw bottle lock may include a retainer configured to secure a cork onto a bottle by a screw-on attachment of the retainer to the bottle. A method may include adding contents to a bottle and sealing the bottle using a cork secured to the bottle using a cork screw bottle lock.

A disclosed bottle opener includes a probe and a temperature sensor circuit coupled to the probe. The temperature sensor circuit is configured to measure a temperature of contents of a bottle. The bottle opener includes a corkscrew coupled to the body and configured to remove a stopper from the bottle. The bottle opener includes a communication circuit configured and arranged to wirelessly communicate with an external electronic device. The bottle opener includes a power circuit configured and arranged to supply power to the communication circuit, and the temperature sensor circuit.

A bottle cap opener can include a drive assembly having knuckle body having a rack gear, and a pinion coupled to the rack gear, where rotary movement of the rack gear can cause translation of the pinion. The bottle cap opener can also include a worm assembly coupled to the drive assembly, the worm assembly including a cork screw that is configured to remove a bottle cap; and a handle assembly having a handle, where the handle can be coupled to the knuckle body to rotatably move with the knuckle body about a first pivot axis and rotatably move relative to the knuckle body about a second pivot axis. Related methods are also provided.
