Abstract: A synchronous switch valve core with a voltage stabilizing function, comprising: a valve core housing (1), a valve core base (2), a flow regulating module, and a balancing hydraulic module. The flow regulating module is capable of cutting off a cold/hot water path before water enters a pressure balancing module, thus preventing high-temperature water from immersing the valve core, preventing the building of lime scale, protecting the valve core, and extending the service life; moreover, water flow can enter the pressure balancing module only after flowing through the flow regulating module, thus preventing the channeling of hot and cold, and obviating the need to install a check valve at a water intake elbow.

Abstract: A lock device may include a slider assembly including a first slider, a second slider movably coupled to the first slider, and a base having a planar portion with a top rail and a bottom rail that hold the slider assembly and allows the relative movement of the first slider relative to the second slider along the top and bottom rails in the base. The second slider can move relative to the first slider to different positions including a latch lock position, a latch unlock position, and a latch impending lock position. The lock device may also include a latch assembly attached to a chassis. The latch assembly including a latch element is configured to move to a first, a second, and a third heights from the top rail of the base corresponding to the latch lock position, the latch unlock position, and the latch impending lock position of the slider assembly, respectively.

Abstract: An apparatus provides a latch with a rotary dial and a leaf spring with teeth that extend from a frame into an engaging position. Inward axial movement of the dial causes the dial to deform the leaf spring and the teeth to extend into the engaging position. In the engaging position, the dial supports the teeth and resists forces that might otherwise cause the teeth to unlatch. In the engaging position, a catch in a track on the dial engages a pin of the frame to maintain the engaging position. From the engaging position, a rotation of the dial unseats the catch and allows the dial to move axially outward and the teeth to recede into the frame.

Abstract: A water flow rate automatic control module, relating to the field of thermostatic shower fittings. The water flow rate automatic control module comprising a base, a valve body, a thermosensitive assembly, a diaphragm, wherein a temperature sensing part senses the temperature of passing cold water in real time; when the temperature of cold water is too low, the mixed water flow rate is slowed down, and more hot water is supplied to a thermostatic valve core assembly for mixing; when the temperature of cold water is too high, the mixed water flow rate is increased, and more cold water is supplied to the thermostatic valve core assembly for mixing. Therefore, the mixed water temperature range of the thermostatic valve core assembly can be ensured, and the problem of temperature adjustment failure or beyond the temperature difference caused by matching the thermostatic shower with a gas water heater is solved.

Abstract: A latch includes a housing, a leaf spring, a tooth, and an actuator. Motion of the actuator against the leaf spring causes the leaf spring to deform and the tooth to extend from the housing to engage a keeper.

Abstract: A latch includes a pin held in a set position by a trigger. The trigger, when depressed, allows the pin to extend from a chassis and engage a rack, preventing the chassis from being removed from the rack. A handle allows the pin to be retracted, with a reset catch maintaining the pin in the retracted position. The trigger, when released, dislodges the reset catch and the pin returns to the set position maintained by the trigger.

Abstract: A latch includes a cam arm that follows a serpentine groove in the latch handle where curves of the groove create catch positions that define extended and retracted handle positions. In one of the handle positions, an arm of the handle abuts a toothed arm and urges the toothed arm to a latching position in which a tooth is extended. In the other handle position, the arm retracts from the toothed arm, allowing the tooth to retract.

Abstract: An expansion device is disclosed for including a plurality of modular devices within a pre-defined volume, such as the drive bay of a computing device. The expansion device may include a standardized bus connection and circuitry connecting to a controller chip, circuitry electrically coupling the controller chip to a plurality of modular devices, and a housing that houses the controller chip, connecting circuitry, and modular devices and that fits within the pre-defined volume.

Abstract: An apparatus for securing a cable access includes a first cable opening in a top plate of a server rack with a tray affixed to the interior side of the top plate and with a second cable opening that overlaps the first cable opening. A hatch element is movable in a space between the plate and tray to cover up the unneeded areas of the first and second cable openings after cables have been installed. A ratchet and pawl attached to the tray and hatch element cooperate to allow movement of the hatch element in a closing direction and resist movement of the hatch element in an opening direction, with a release element disengaging the ratchet and pawl to allow the hatch element to open.
