摘要： A system for providing an electrical steering assist for a materials handling vehicle includes a drive housing; a steerable wheel coupled to the drive housing; a steering arm pivotally mounted to the drive housing; a steer drive unit coupled to the steerable wheel; an input sensing device; and a controller. The steering arm is operatively configured to determine a steering direction of the steerable wheel. The input sensing device is arranged to detect a turning force applied to the steering arm by an operator, wherein the turning force is provided to change the angle of travel of the vehicle. The input sensing device includes a strain measuring assembly defining a strain sensitive region between the steering arm and the steer drive unit. The controller is operatively configured to control the steer drive unit to turn the steerable wheel based upon a signal from the input sensing device.

A piston is slidably carried in the tube on a piston rod. A coil is carried on the piston adjacent a first flow passageway in the piston to produce a magnetic field thereacross and a control valve is carried on the piston controlling fluid flow through a second flow passageway in the piston. The control valve is positioned at the distal end of the rod upstream of the first flow passageway.

摘要： A reusable and refillable insect bait container having insect base passageways to its interior bait reservoir, a removable top cap, and a lower ground engaging support stake member. The ground engaging stake member has upper protrusions that engage base notches to hold these two components together. The cap has a lower mating indent which engages a protruding member on the base to hold these components together in a snap fit relationship. When access to the base's reservoir is desired, the removable cap is pulled off by a tab and the bait needed inserted. Both the base and cap should be made of a flexible weather resistant material, such as rubber or soft plastic, to permit the firmer stake material and its protrusions to easily be inserted in a locking manner into the base.
