A system and method of achieving ride control for a work vehicle that replaces a traditional accumulator with a ride control valve, a directional control valve and a fluid pressure source. The fluid pressure source may be a variable displacement hydraulic pump. The ride control valve is set to a first relief pressure that allows fluid to flow from the head end of a hydraulic cylinder when the loading on the cylinder, i.e., the pressure in the head end is equal to or greater than the first relief pressure. A work tool of the vehicle falls from a first position to a second position when fluid flows from the head end. The ride control valve is then reset to a second relief pressure, higher than the first relief pressure and sufficient to move the work tool toward the first position. Afterwards, the directional control valve is opened long enough to allow fluid from the fluid pressure source to enter the head end and move the work tool back to approximately the first position. The ride control valve may be dynamically adjusted.

A method for cleansing a desired skin surface, and a device therefor, can include a base to house a jar for the cleansing liquid, a jar for the removed liquid and debris, a pump to deliver the cleansing liquid to a wand applicator, and a pump to suction the cleansing liquid and debris removed from the desired skin surface. The two pumps can be driven by separate motors to allow a user to separately control the amount of liquid dispensed and the magnitude of the suction force applied. The device can also include an infusion enhancer that assists in the opening of the pores of the desired skin surface or by tightening the desired skin surface. The device can further include a self-cleaning tip that allows a cleaning solution to be immediately recycled through the system into the jar for the removed liquid and debris.

The present disclosure relates to a ladder-mountable storage device for storing and retractably deploying a flag. The flag can be displayed on the end of a ladder to warn onlookers. If used on the end of a ladder extending from a vehicle, the flag warns drivers to keep a safe distance, for example. The ladder-mountable storage device can also be attached to the top of ladders placed alongside buildings and other structures.
摘要:
A method, computer program product, and computer system for intelligently assigning a work task to an agent. From a database, the computer system retrieves information of a location of the work task and information of agent locations determined by a satellite navigation system. The computer system selects one or more candidate agents who are within a predetermined range of the location of the work task, based on the agent locations determined by the satellite navigation system. Retrieving network node data and location information of routers or repeaters in a network, the computer system determines locations of the one or more candidate agents. The computer system chooses a best available agent for the work task from the one or more candidate agents, based on the location of the work task and the locations of the one or more candidate agents.

A flow directing material includes a substrate. The substrate includes a first region that exudes fluid under a compressive or tensile load and a second region that imbibes fluid under the compressive or tensile load. The first region has a first porosity and a first permeability and the second region has a second porosity and a second permeability. The first permeability and the second permeability are about 10−13 m2 to 105 m2. The first porosity and the second porosity are about 0.3 to about 0.7. The first porosity and the second porosity are at least about 5% different.

A gauge mounting bracket for a snowmobile that allows hot gas in the engine compartment to circulate and escape through a plurality of side vent openings formed thereon. The mounting bracket allows the user to adjust the angular position of a speedometer or tachometer gauge on the dashboard of a snowmobile to accommodate riders who sit or stand while driving. The mounting bracket includes lower dashboard mounting surface and an upper gauge mounting surface. The lower dashboard mounting surface is flush mounted on the existing dashboard of a snowmobile while the upper gauge mounting surface is tilted upward and aligned 5 to 50 degrees from the dashboard mounting surface. During assembly, the mounting bracket is mounted over an existing or newly created hole in the dashboard that leads to the engine compartment. Heated air created in the compartment travels upward and rearward and then escapes through the vent openings.

An improved jack assembly for use with a trailer tongue of a towed vehicle. The jack assembly including telescoping height adjustment of the assembly, a pivot assembly for pivoting between a vertical and horizontal stowed position, and a clip for maintaining a handle assembly in a stowed position when not in use. The jack assembly also includes the use of bushings for the telescoping tubes to enhance the sliding movement between the tubes and aid in maintaining the axial alignment of the tubes thereby extending the life of the jack assembly. The pivot assembly further includes an attachment bracket that may be rotated to accommodate at least two different sizes of trailer tongues.

Systems and methods are disclosed for detecting the connection of a FireWire peer to a FireWire device. In one embodiment, a device may determine whether a peer connection is present based on peer detection circuit configured in each FireWire port of a FireWire device. When no peer is connected to a device, a peer connection in the circuit may be open, and a current path through the circuit may provide a low detect signal, indicating that no peer is connected. When a peer is connected to a detecting device, the current may pass through a resistance in the detected peer to provide a high detect signal, indicating that a peer is connected. In some embodiments, once a peer is detected, the FireWire system of the detecting device may be powered on, and the peer detection circuit may be powered off.

Techniques for graph data structure management. In one aspect, a data structure includes a plurality of nodes connected by edges. A node of the data structure includes a current set of variables for defining a state of the node and at least one last-in, first-out stack for storing pointers to prior sets of variables for the node. The state of the node may be saved by adding a pointer to at least one of the stacks at the node. The state of the node may be restored by removing the pointer from the stack and restoring the node variables to those indicated by the pointer. A first counter associated with a stack at the node may store a number of pending saves at the node, while a second counter may store a number of saves to be propagated to descendents of the node. A state of the data structure may be saved by traversing other nodes of the data structure and adding pointers or incrementing counters at the nodes.
