Abstract: A storage rack for a plurality of water bottles, including: a plurality of shelves; a plurality of levelers each being configured to support the storage rack, each leveler of the plurality of levelers is operably coupled to one of a plurality of potentiometers that is located between the each leveler of the plurality of levelers and a portion of the storage rack, the plurality of potentiometers are operably coupled to a analog to digital converter that sums signals of the plurality of potentiometers and provides an indication of an amount of weight being supported by the storage rack, the amount of weight being associated with an amount of water bottles being supported by the storage rack.

Abstract: An electronic lock, including: a power storage device; and a means for providing power to the power storage device.

Abstract: A lock including: a retractable knob; and a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism retains the retractable knob in the retracted position until a motor of the knob release mechanism is actuated by an input provided to a keypad located on a surface of the lock.

Abstract: An electronic lock, including: a power storage device; and photovoltaic cells located on a surface of the electronic lock, the photovoltaic cells being electrically coupled to the power storage device in order to provide a charging current to the power storage device.

Abstract: A lock including: a retractable knob; and a knob release mechanism for retaining the retractable knob in a retracted position, the knob release mechanism retains the retractable knob in the retracted position until a motor of the knob release mechanism is actuated by an input provided to a keypad located on a surface of the lock.

Abstract: A lock, including: a retractable knob; and a knob release mechanism for retaining the retractable knob in a retracted position, wherein the knob release mechanism includes a damper with a gear that is slidably received within a set of grooves located in the retractable knob, and wherein the gear prevents rotation of the retractable knob unless it is in an extended position.

Abstract: A locking device and a method for unlocking the locking device are provided. The locking device includes a stationary plug having a first aperture extending therein configured to receive a key. The stationary plug further includes an outer surface, an inner surface defined by the first aperture, and at least a second aperture extending from the outer surface to the inner surface. The locking device further includes a housing having an outer wall disposed around at least a portion of the stationary plug. The outer wall has at least a third aperture extending therethrough. The locking device further includes a bolt member operably coupled to the outer wall of the housing. The locking device further includes a locking mechanism disposed in the third aperture of the housing and extending into the second aperture of the stationary plug. The locking mechanism is configured to allow rotation of the housing about the stationary plug when the key is inserted into the first aperture.

Abstract: A dynamic interaction and feedback system for simulating the accumulation of consequence to enhance interactive content comprises logic for determining an agent group at a state of the system (20), an active agent selection interface so that a participant may select an agent from the agent group to be a present active agent (22), active controls selection logic for selecting an active controls set related to the present active agent at the state of the system by which the participant may interact (24), and a feedback memory for recording the occurrence of feedback for the purpose of subsequent reference during operation of the system (26).
