Abstract: A heater assembly designed for use with a vaporizer. The heater assembly including a housing with a heat exchanger. The heat exchanger extends from a first end to a second end. The heat exchanger defines at least one air flow path that extends through the heat exchanger from the first end to the second end. The housing is configured to retain a substance adjacent the second end for heating. A heating element extends around at least a portion of the air flow path with a portion of the heat exchanger positioned between the heating element and the air flow path. The heating element is configured to heat the heat exchanger, and the heat exchanger is configured to transfer heat from the heating element to air flowing through the air flow path from the first end to the second end. Alternatively, the heat exchanger heats as electric current flows through it.

Abstract: An improved transfer board adapted to facilitate the transfer of a person between a wheelchair and another surface, the transfer board having a rigid body member and a multilayer sliding surface member adhered to the upper surface of the body member, the multilayer sliding surface member having a hydrophilic upper contact layer, most preferably with a wetting contact angle of less than approximately 20 degrees.

Abstract: A multi-component pallet includes a first deck and a second deck. The first deck can be configured to be removably connected to the second deck in a first position for use in the load-bearing assembled state. The first deck can also be configured to be nested with the second deck when the pallet is in the unloaded, disassembled state. The first deck and the second deck can be configured such that the volume of the pallet in the load-bearing assembled state is greater than the volume of the first deck and the second deck when they are nested in the unloaded, disassembled state.
