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 method of manufacturing an electrolytic capacitor includes impregnating an electrolytic capacitor with a first electrolyte to form a first impregnated capacitor, aging the first impregnated capacitor using a first aging process to form a first aged capacitor, impregnating the first aged capacitor with a second electrolyte to form a second impregnated capacitor, the second electrolyte being different from the first electrolyte, aging the second impregnated capacitor using a final aging process to form a final aged capacitor, and impregnating the final aged capacitor with a third electrolyte.

Abstract: A method of manufacturing an aluminum electrolytic capacitor includes impregnating an aluminum electrolytic capacitor with a first electrolyte to form a first impregnated capacitor, aging the first impregnated capacitor using a first aging process to form a first aged capacitor, impregnating the first aged capacitor with a second electrolyte to form a second impregnated capacitor, the second electrolyte being different from the first electrolyte, aging the second impregnated capacitor using a final aging process to form a final aged capacitor, and impregnating the final aged capacitor with a third electrolyte.

Abstract: A chemical etch is performed on a sheet of material. An electrochemical etch is performed on the sheet of material after the chemical etch is performed on the sheet of material. A capacitor is fabricated such that an electrode included in the capacitor includes material from the sheet of material after the electrochemical etch was performed on the sheet of material. In some instances, the chemical etch included at least partially immersing the sheet of material in an etch bath that includes molybdenum. Additionally or alternately, the chemical etch can be performed for a period of time less than 60 s.

Abstract: A casement window operator, including: a first arm; a second arm, the first arm and the second arm each being rotatably mounted to the casement window operator and the first arm and the second arm each having a toothed peripheral portion for meshingly engaging a worm rotatably received in the casement window operator, such that rotation of the worm about its axis of rotation will cause the first arm and the second arm to rotate with respect to the casement window operator; and a damper located between the worm and a housing of the casement window operator, wherein the damper has a pair of anti-rotation features each being located about an exterior peripheral portion of the damper, the pair of anti-rotation features extending outwardly from the exterior peripheral portion of the damper and wherein the pair of anti-rotation features are configured to be received within a corresponding pair of openings of the housing of the casement window operator.

Abstract: A dispenser has a fastening mechanism having a fastened configuration that fastens a cover of the dispenser to a base of the dispenser, and an unfastened configuration that allows the cover to open from the base. The fastening mechanism has a locked state in which the fastening mechanism requires a key to move from the fastened configuration to the unfastened configuration and an unlocked state in which the fastening mechanism is movable from the fastened configuration to the unfastened configuration without the presence of the key. A release member is actuable by a button without the presence of the key to open the dispenser when the fastening mechanism is in the unlocked state, and the release member is actuable by the key to disengage the release member from the cooperating member when the fastening mechanism is in the locked state.

Abstract: A handle arrangement includes a handle transitionable between an undrawn configuration and a drawn configuration. A handle lever can be coupled to a rotational member and configured to rotate the rotational member as the handle is transitioned to the drawn configuration. The rotational member can be configured to actuate a cam lever. The cam lever can be configured to actuate a latch cam between a first position corresponding to the undrawn configuration of the handle and a second position corresponding to the drawn configuration of the handle. The latch cam can be configured such that transitioning the handle between the undrawn configuration and the drawn configuration causes the latch cam to transition from the first position to the second position. The latch cam can initially move in a direction away from the second position before arriving at the second position.
