An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

A dust mitigating device is provided for use in debris handling. A dust mitigating device may comprise a rake having a head and a first axis, a collection head coupled to the rake, and an exit passage in fluid communication with the collection head. The collection head comprises a suction port and has a second axis. The collection head is configured to align with the head of a rake such that the second axis substantially parallel with the first axis and proximate the first axis. The exit passage is configured to couple to a negative pressure source.

A motorized lute includes a first plate having a first plurality of teeth and a second plate having a second plurality of teeth. The second plate is slidably coupled to the first plate. A motor assembly is configured to engage the second plate provide a lateral force to the second plate and cause horizontal oscillation of said second plate. Wheels are disposed on each side of the first and second plate. A lute pole is coupled to the first plate and includes a primary handle and actuator for controlling speed and power of the motor.
