Abstract: In one embodiment, an apparatus includes a body. At least a portion of the body includes one or more instances of magnetic material. The apparatus includes a moveable element coupled to the body and separated by a distance in a first dimension from the portion of the body. The moveable element includes one or more instances of magnetic material, and is configured to move in at least a second dimension perpendicular to the first dimension while the distance between the moveable element and the portion of the body remains fixed by the apparatus. At least one instance of the magnetic material in the moveable element repels or attracts at least one instance of the magnetic material in the body.

Abstract: A corkscrew assembly includes a housing a worm screw assembly, a first gripper, and a second gripper. The housing defines (i) a first opening configured to receive a neck of a bottle, (ii) a second opening, and (iii) an interior space interposed between the first opening and the second opening. The housing includes a sidewall extending from the first opening to the second opening. The sidewall defines a first gripper passage and a second gripper passage. The interior space is interposed between the first gripper passage and the second gripper passage. The worm screw assembly is rotatable in relation to the housing and includes (i) a worm screw member having a pointed first end portion and a second opposite end portion and (ii) a drive member fixed in relation to the second opposite end portion.

Abstract: In one embodiment, a device includes a device body that includes a touch-sensitive display and a processor. The device also includes a band coupled to the device body and an optical sensor in or on the band. The optical sensor faces outward from the band and captures images. The processor communicates with the optical sensor to process captured images.

Abstract: In one embodiment, a wearable device includes a body that includes a touch-sensitive display. The wearable device includes a band coupled to the body and an optical sensor placed on or in the band so that an image of an object displayed on the touch-sensitive display is viewable while the object is also viewable without the wearable device blocking a view of the object.
