Abstract: The invention provides for a DC brush-arc furnace comprising a vessel 12 and first and second electrodes 16, 18. A first DC power supply 20 supplies power to the electrodes. A first conductor 26 extends parallel to the first electrode, so that a first current flows in a first direction through the first conductor and in a second opposite direction in the first electrode. A second conductor 28 extends parallel to the second electrode, so that the current flows in the first direction in the second electrode and in the second direction in the second conductor. An arc deflection compensation system 30 comprises a second DC power supply 32 and a compensation circuit 34 comprising a first compensation conductor 36 and a second compensation conductor 38. The second DC power supply causes a second current to flow through the first compensation conductor in the first direction and through the second compensation conductor in the second direction.

Abstract: Methods and systems for recommending at least one patient interface device from among a plurality of patient interface devices for a patient. The methods and systems monitor an initial stress response of the patient upon being exposed to each of the potential patient interface devices of the plurality and from such monitoring select a device or devices that produce lesser stress responses.

Abstract: A disclosed modular truck bed assembly includes two or more modular truck bed components configured to form a modular truck bed suitable for use with a bedless truck. The modular truck components may include two or more modular components that combine to form a multi-piece bed panel. The modular components that combine to form the multi-piece bed panel may include a center bed module attached between left and right wing bed modules. The center bed panel may be affixed to structural elements of the bedless while the wing bed modules may be attached to the center module. The center bed module may include a center bed panel, with or without a gooseneck hitch, and a center trail panel, without or without a trailer hitch. The assembly may include a vertically adjustable bulkhead positioned forward of the center bed panel and either side of the assembly may include a skirt.

Abstract: A measuring tape device may include a housing having an aperture, a reel assembly defining an axis, a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly, and a transverse aperture extending through the housing in a direction substantially parallel to the axis.

Abstract: A headache rack system for a truck includes a truck bed and a removable and vertically adjustable headache rack. The truck bed is adapted to be attached to a truck frame and includes a floor and a side panel connected to the floor. The side panel includes a first flange and a second flange. The removable headache rack includes a first side support, a second side support, a top support connected to an upper end of the first side support and an upper end of the second side support, and a panel connected to a lower end of the first side support and a lower end of the second side support. The first and second flanges, respectively, may extend beyond a leading edge of the floor and wrap around a portion of the front of the truck bed to define a slot configured for receiving the lower ends of the first and second side supports.
