Abstract: A portable heating or lighting unit may comprise a housing, a handle, a shield or grid, a source of electric energy, a rectifier, an electrical device adapted to use electrical energy from the source of electric energy, and a control system comprising control hardware and embedded software, where the control system may be adapted to automatically control the electric heating element. A source of electric energy may comprise a battery adapted to store energy and to output stored energy as electrical energy, a fuel cell, a thermoelectric component, or a plug adapted to draw electrical energy from a wall outlet or other source of electrical energy. A battery may be at least partially enclosed by the housing. A thermoelectric component may comprise a thermoelectric material or a thermoelectric generator. An electrical device may comprise a resistive heating element adapted to emit thermal energy.

Abstract: A crossbow may include a main beam; a compound bow assembly mounted to the main beam including a riser and a pair of bow limbs; and a trigger mechanism mounted to the main beam for use in holding a bowstring in a cocked position. The crossbow may include wheels at opposite ends of the bow that operatively receive the bowstring. The wheels may be separated by a wheel distance (WD) when the crossbow is in an un-cocked position. The crossbow may also have a power stroke distance (PD) and the ratio WD/PD may be less than 2.0. The crossbow may include a foot stirrup being integral with the riser, the foot stirrup beginning behind the pair of bow limbs and extending beyond the bow limbs.

Abstract: An organic foliage compactor for compacting organic foliage into a bale is disclosed. The compactor includes a compactor frame and a compacting tube coupled to the compactor frame. The compacting tube includes a first end, a second end and a housing that defines an interior passage extending between the first end and the second end through which the organic foliage is urged to compact the organic foliage. A feed tube to which the organic foliage is to be introduced is in communication with the compacting tube. A driver provides an urging force to be imparted on organic foliage introduced to the feed tube, and a platen is operatively coupled to the driver for urging organic foliage introduced to the feed tube into the compacting tube where it is compacted as the organic foliage progresses through the interior passage defined by the housing between the first end and the second end of the compacting tube as a substantially steady-state process.
