A material handling vehicle guidance system comprises a first conductive member, a second conductive member, and an electrical current source. The second conductive member is electrically coupled to the first conductive member and extends parallel to the first conductive member to define a loop. The first conductive member and second conductive member are coupled to a shielded cable connector. The electrical current source supplies current to the first conductive member in a first direction and supplies current to the second conductive member in a second direction opposite the first direction to produce a narrowcast radio frequency signal detectable between the first conductive member and the second member.

Wire guidance and remote operation for material handling vehicles

Systems and methods for material handling vehicle simulation are provided. In one aspect, a material handling vehicle simulation system includes a material handling vehicle having a plurality of controls operable to manipulate the material handling vehicle to perform a desired operation, and a vehicle controller configured to selectively transition between a standard mode where the vehicle controller is configured to instruct the vehicle to perform standard operating tasks and a simulation mode. The material handling simulation system further includes a simulation kit having a simulation display, and a simulation controller in communication with the plurality of controls and the simulation display. When the vehicle controller is in the simulation mode, the simulation controller is configured to simulate operation of the material handling vehicle on the simulation display in response to manipulation of at least one of the plurality of controls.

Systems and methods for vehicle simulation

A lift truck includes systems and methods for improved vibration control. A corrective yaw input mechanism reduces or eliminates torsional vibration motion of the lift truck about the Z-axis. Some embodiments may include, alone or in combination, drive wheel control and load wheel control.

Vibration control systems and methods for industrial lift trucks

Disclosed is an apparatus for rapidly screening chemicals for their ability to sublime. The apparatus consists of a heated well plate, where the chemicals are deposited, and a cooled finger plate, holding fingers that penetrate each well. The two plates touch at only the perimeter in order to facilitate a vacuum seal and to reduce any thermal transfer.

Sublimation screening test and apparatus

An apparatus and method for stretching a carpet includes the application of a downwardly directed actuation force on a foot-operated pedal actuator to generate a horizontally directed carpet stretching force. An extension arrangement included either fixed length and/or adjustable length truss members is used to anchor the carpet stretching apparatus.

A method of shaping elongated composite structures of a resin matrix reinforced with randomly broken fibers oriented in transverse and non-transverse directions with respect to the longitudinal axis of the structure is implemented by a computer aided apparatus for forming the structure. The apparatus is provided with a heated fixed forming tool, a means for stretching the structure from each end and means associated with the forming tool for separately holding each formed component length of the structure in place against the forming tool. The formed structure is characterized by the particular orientation of the fibers in the transverse and non-transverse direction after the structure is formed.

A computer-aided method for predicting the layup of fiber-reinforced prepreg resin material for compression molding into three-dimensional shapes depends on the area relationships of the final thickness of the molded shape to the initial thickness of the prepreg material. A graphic display is generated incorporating the initial thickness needed at each location on the prepreg material to provide the desired final thickness of the three-dimensional shape with controlled fiber distribution throughout the shape.
