Abstract: Evaporative humidifiers comprising: in vertical relationship and fluid communication with each other, a water inlet and a water reservoir downstream therefrom, positioned to receive water along a first fluid path; air inlet(s) and air outlet(s) in vertical relationship with the water inlet and/or reservoir, and a wick, downstream the water inlet, partially disposed in the reservoir to draw water therefrom to a wick portion in fluid communication with the air inlet(s) and the air outlet(s); and a motor-fan assembly downstream and in vertical relationship with the water inlet, upstream the reservoir. The reservoir and one or more of the air inlet(s) and the air outlet(s) generate an air current for drawing air, via the air inlet(s), from an external environment through the wick portion and move moistened air to the external environment via the air outlet(s) along a second fluid path at least partially separate from the first fluid path.

Abstract: The pet restraint system sheaths a restraint strap between an outer waterproof layer and an inner breathable fabric layer. These layers are oversized relative to the strap and do not extend the entire length of the strap. This arrangement is advantageously used in a pet collar structure, or a pet restraint harness. It has particular application for a dog collar or a dog restraint harness.
