Abstract: A cleaning tool including a holding rod and a first tool assembly connected to the holding rod. The holding rod includes a first rod body, a second rod body pivotally connected to the first rod body, and a fixing structure disposed on either the first rod body or the second rod body and having an engaging portion. The other one of the first rod body and the second rod body not disposed with the fixing structure has an engaged portion correspondingly and detachably engaged with the engaging portion. When the engaging portion is engaged with the engaged portion, the first rod body is correspondingly connected to the second rod body to make the holding rod has a maximum length. When the engaging portion is disengaged from the engaged portion, the first rod body and the second rod body is controllably folded to each other, making the cleaning tool has a smaller volume.

Abstract: A drainage device includes a conduit extending from a bottom end toward a top end and a valve coupled to the conduit. The valve includes a first stop having an opening and an obstruction within the conduit. The obstruction, in a first configuration, may be spaced apart from the opening, enabling fluid to flow through the first stop and through the conduit. The obstruction, in a second configuration, may block the opening to prevent fluid flow through the first stop and through the conduit. The obstruction may move from the first configuration to the second configuration in response to (1) fluid pressure acting in a direction from the bottom end toward the top end of the conduit, or (2) when a fluid having a higher density than the obstruction is disposed within the valve.

Abstract: The present invention generally related to a maple sap lifter configuration and to a sap collection system making use of the sap lifter. The system includes a vacuum pump, a number of pipes, and the sap lifter. The sap lifter includes a body; an inlet for conveying sap towards the sap lifter; a first outlet for conveying the sap away from the sap lifter; and a pump operatively coupled to the pipes and adapted to pump the sap away from the body once a maximum level of sap is reached, and wherein the maximum level of sap is set to leave an air space in the body and in the pipes for maintaining the level of constant vacuum. The sap lifter and the pipes alternatively define a closed-circuit with no fluid communication with ambient air for maintaining the level of constant vacuum.

Abstract: An apparatus is provided for ensuring the proper orientation of an electronic device within a rack slot. A constraint is added to one of a pair of rail assemblies and a corresponding constraint is added to the rack, the pair of constraints cooperating to allow the pair of rail assemblies to be installed only in the proper sides of the rack. Mounting holes are provided on the device and inner rails of the rail assemblies that allow the inner rail assemblies to be installed only on the proper sides of the device. A key and key slot combination is then provided in an inner rail and a middle rail of one rail assembly with the combination preventing the inner rail from being fully inserted into the incorrect middle rail. Thus, the correct orientation of the device is ensured by the pair of rail assemblies, the spacing of mounting holes in the device, and the rack constraint.

Abstract: An elevator provides for lifting and disconnecting an electronic device from a chassis circuit board and the subsequent removal of the device from a chassis slot. A sliding element between the device and the slot includes tracks within which travel followers associated with the electronic device. Motion in a first direction the tracks causes the tracks to move with respect to the followers, raising the device away from the circuit board. In a fully raised position, the device is disconnected and may be removed from the slot. Motion in the opposite direction causes the relative motion between the track and follower to lower the device toward the circuit board. In a fully seated position, the device is connected to the circuit board.

Abstract: An apparatus is provided for the simultaneous transferring of multiple storage devices from a chassis to reduce service time and associated server temperature fluctuations. The storage transfer device may be mounted to a chassis with a multitude of electronic devices, e.g., a JBOD with HDDs, above the devices to be removed. The storage device may then be manipulated to mechanically unlatch the devices from the chassis and simultaneously attach the devices to the transfer device. The devices may then be disconnected and withdrawn from the chassis and pulled into the storage transfer device. The devices may be re-installed later using the storage device and the reverse process.

Abstract: Embodiments promote the maintenance of a designed flow of cooling air through a chassis during the servicing of one or more electronic components contained by the chassis. A top opening created by the removal of server chassis from a rack may be significantly reduced by internal lids that provide access to groups of components. Gaps created by the partial removal of groups of components may be significantly reduced by air dams attached to the components that inhibit the flow of air between the components. And the opening created by the removal of a circuit board may be significantly reduced by a flap configured to cover the opening upon removal of the circuit board. The various embodiments may be used individually or in combination to reduce openings in the chassis that may allow air to flow in paths that negatively affect the designed air flow.

Abstract: A configurable PCI card for connecting to a PCI interface is disclosed. The configurable PCI card comprises a bus interface disposed on a base card for communicatively connecting to a bus of a computing device. The configurable PCI card further comprises a bracket for physically securing the base card to the computing device. The configurable PCI card also comprises a wire layout disposed on the base card for replicating a plurality of different power and heat generation profiles that correspond to a plurality of different chipsets.

Abstract: An interlock system is provided that limits the ability of a user or seismic event to dislodge or partially remove more than one chassis from a rack at any one time. Thus, embodiments reduce the potential for the rack to be toppled by the weight of too many chassis extending from the rack at the same time. The interlock system includes a dynamic rail with locking blocks that move to engage hooks on the rear of the chassis. A trigger at each chassis slot is depressed with installation of a chassis. Upon the removal of any chassis, the associated trigger extends and causes the dynamic rail to be pulled down into a locking position in which the locking blocks engage the hooks on the remaining chassis, which prevents their removal.

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 carrier of an electronic device is provided with a soft stopper that may maintain the carrier at a service position within a chassis slot. As the carrier is inserted into the slot, at a determined point the soft stopper impinges upon a bumper. Further movement of the carrier into the slot requires the user to force the soft stopper to compress or flex and bypass the bumper. With the chassis slot vertically oriented the soft stopper may maintain the carrier and electronic device in service position, disconnected, while service is performed on a chassis circuit board.

Abstract: Systems and methods are described for controlling inrush current for a system comprising a plurality of metal-oxide-semiconductor field-effect transistors (MOSFETs). The system may include a control circuit coupled to parallel series of gate drivers, where each gate driver is coupled to a different MOSFET. An inrush current may be received during charging of a capacitor of the switch circuit. During a first period of a ramp time, the control circuit may cause the inrush current to pass through a first gate driver. During a second period of the ramp time, the control circuit may cause the inrush current to pass through a second gate driver. By using a control circuit to cause the inrush current to pass through each MOSFET, a gate-source threshold voltage for the MOSFETs may remain below safe operating areas (SOAs) for the different MOSFETs.
