Abstract: An in-tank illumination system and method for a translucent tank with sensors configured to monitor conditions of the tank and material inside. The illumination system includes an illumination source that illuminates the tank interior and is visible outside; and a controller that determines tank conditions based on the sensor readings, and sends control signals to the illumination source. When the controller detects a tank condition, it sends control signals to the source to illuminate the tank to indicate the tank condition. The system can include a bracket connecting the source to the tank interior near the top. The controller and source can be on different vehicles. Different control signals can change colors, blink patterns, and other properties of the source to indicate different tank conditions. The tank conditions can have different priorities to select which to indicate. The severity or duration of tank conditions can also be indicated.

Abstract: A hand-held cleaning device that utilizes a low-power, low-torque motor coupled to an impeller for creating a vacuum. The device includes a contact head having a plurality of protrusions formed on its top surface. The contact head contacts the surface to be cleaned, for example, the coat of a pet. The protrusions are sized and spaced to avoid tangling or clumping of pet hair. The device includes a container for collecting hair and debris. The impeller includes ribs on a disk portion thereof for increasing the efficiency of the vacuum system.

Abstract: A tool for collecting waste in a bag, comprising an elongated shaft member, a ring member, and two clamps. The tool provides for the securing of a bag on the ring member such that no part of the ring member or the outside surface of the bag may come in contact with the waste to be collected. The tool utilizes an arcuate ring member and there is substantially no angle between the ring member and the elongated shaft member.
