摘要:
At least one electrical contactor is provided that includes a fixed contact and a movable contact. The fixed contact includes a center leg and first and second arms that extend in opposite directions from the center leg. The movable contact associated with each fixed contact includes first and second blades positioned on opposite sides of the center leg. The first and second blades extend parallel to the center leg of the fixed contact such that when current flows through the electrical contactor, the current flow creates a force to push the first and second blades into the first and second arms of the fixed contact. The electrical contactor includes an actuating arrangement having a pair of cam members. The movement of the cam members causes pegs on each of the first and second blades to travel within the cam channel, thus opening and closing the contactor arrangement.

摘要:
A magnetic latching actuator operable to control the movement of at least a first contact and second contact between a closed position in which the contacts physically engage each other and an open position in which the contacts are spaced from each other. The magnetic latching actuator includes first and second stationary permanent magnets oriented such that the first magnetic field created by the first magnet and the second magnetic field created by the second magnet are in opposite directions. An actuation coil surrounds both the first and second magnets. Current is supplied to the actuation coil in a first direction to create a first magnetic field or a second direction to create a second actuation magnetic field opposite the first actuation magnetic field. A yoke is movable relative to the first and second magnets to cause the first and second contacts to move between the open and closed positions.

摘要:
The invention relates to a medicament-containing dispenser, such as an inhaler. The dispenser comprises an outlet for dispensing medicament, e.g. a mouthpiece or a nasal adaptor. The dispenser also comprises a display for presenting indicia to a user. The dispenser further comprises an outlet cover movable between a first position in which it covers the outlet and a second position in which the outlet is uncovered, wherein, when said outlet cover is in said first position, indicia is visible said display, and wherein, when said outlet cover is in said second position, indicia is out of sight to the user.
摘要:
A fluid consuming battery (10) is provided with a fluid regulating system (50) for regulating fluid entry into the battery. The battery (10) includes a fluid consuming cell (20) having a cell housing with fluid entry ports for the passage of a fluid into the cell housing. A first fluid consuming electrode and a second electrode are disposed within the cell housing. The fluid regulating system (50) includes a valve having a moving plate (66) disposed adjacent to a fixed plate (62). The moving plate and fixed plate both have fluid entry ports (68, 64) that align in an open valve position and are misaligned in a closed valve position. The fluid regulating system (50) also includes an actuator that may include one or more shape memory alloy (SMA) components (82a, 82b) for moving the moving plate (66) relative to the fixed plate (62) to open and close the valve.
