摘要:
In one aspect, the present invention contemplates a strapping station that integrates with a machine for wrapping and clamping a strap around a load, particularly a palletized load. The strapping station includes a transfer conveyor and a compression conveyor that is supported to be lowered onto the upper surface of a load to apply pressure to or compress the load during the strapping operation. The compression conveyor is maintained in that position, continuously applying pressure to the load, even as the load is moved for the application of straps at different locations.

摘要:
An apparatus for dispensing a pallet sleeve beneath a load comprises a conveyor component including conveyor elements configured to convey the load thereon in a first direction, one or more stations spaced apart along the first direction and a mechanism for changing the relative vertical positions of the conveyor elements and the stations. The apparatus further includes a pallet sleeve dispenser adjacent the conveyor component and configured for storing pallet sleeves in spaced apart sections aligned with a corresponding station. A drive element associated with each of the stations is configured to engage a pallet sleeve to drive the pallet sleeve from the dispenser to the conveyor component in a second direction substantially perpendicular to the first direction. A retention mechanism is provided to support a stack of pallet sleeves above a lowermost sleeve being driven from the dispenser to the position underneath the load on the conveyor component.

A load moving apparatus is operable to move a load, such as a stack of sheet product, in a first and second direction on a staging area. The load moving apparatus includes a first conveyor, a second conveyor, and a translating device. The first conveyor defines the staging area and is configured to move a load in a first direction. The second conveyor is positioned within the staging area and is configured to move the load in a second direction different from the first direction. The translating device is configured to move vertically one of the first conveyor and the second conveyor relative to the other of the first conveyor and the second conveyor. The load moving apparatus can be used to build or break down loads entering the staging area.

摘要:
A varactor diode includes a contact layer having a first conductivity type, a voltage blocking layer having the first conductivity and a first net doping concentration on the contact layer, a blocking junction on the voltage blocking layer, and a plurality of discrete doped regions in the voltage blocking layer and spaced apart from the carrier injection junction. The plurality of discrete doped regions have the first conductivity type and a second net doping concentration that is higher than the first net doping concentration, and the plurality of discrete doped regions are configured to modulate the capacitance of the varactor diode as a depletion region of the varactor diode expands in response to a reverse bias voltage applied to the blocking junction. Related methods of forming a varactor diode are also disclosed.

A vehicle tracking system tracks the position of at least one vehicle and displays the tracked position. The system includes a plurality of beacons, at least one provided on each vehicle, configured to emit a corresponding identifying signal. A camera is configured to generate image data including region data based on a region in which the vehicles may be located, and beacon data based on the identifying signals corresponding to the beacons located in the region. A controller is configured to process the beacon data to generate position data based on a corresponding position of the beacons located in the region and to generate identification data, which corresponds to each of the identifying signals emitted by the beacons located in the region. Also, the controller outputs at least one of the image data, the position data, and the identification data to the monitor.
摘要:
A high electron mobility device and method of making is provided whereby a two-dimensional electron gas is formed at a hetero-junction or hetero-interface between different polytypes of a semiconductor material. The different crystal forms or polytypes of the semiconductor material having different electronic bandgaps are used to provide the bandgap necessary to form the two-dimensional electron gas.
