Abstract: A mobile air cleaning device for reducing air pollution emissions from a source by cleaning contaminated air is provided. The air cleaning device includes a tank to hold liquid, an extendable pipe to extend relative to the tank, an air filter to transmit air to the tank, a screen to filter pollution from the source, a pump to circulate liquid in the tank, and a liquid filter to filter pollution from the tank. The extendable pipe includes a fan to draw contaminated air through the extendable pipe to the tank where pollution emissions are captured in the liquid and clean air escapes though an air hole in the tank. A drone may deploy the air cleaning device to an elevation of the air pollution emissions. Advantageously, the air cleaning device militates against air pollution by cleaning contaminated air in a mobile and compact manner capable of reaching various elevations.

Abstract: The present invention relates to a rotating drivetrain assembly comprising a rotating central post in communication with an actuator. The assembly includes a main plate with a first plurality of apertures formed on one side of the central post, and a sprocket wheel with a second plurality of apertures formed on the opposite side of the central post. Two rotating studs are positioned on opposite ends of the central post, between the main plate and the sprocket wheel. This configuration allows for efficient power transmission and rotation of the drivetrain assembly, enabling smooth and reliable operation.

Abstract: A multicolored indicator part and cover part are attached to a truck brake slack adjuster and S cam shaft. Relative motion of the brake slack adjuster and the S cam shaft causes relative motion of the two parts to reveal the colors on the indicator part. Good, warning, and danger colors are provided in highly reflective surfaces seen in a walk around inspection of a truck.

Abstract: A modular communications, command, and control system with plug-and-play connectivity, utilizing configurable independent base stations and portable handsets that preferably have similar components and functionality so as to be interoperable. The system utilizes an open system interconnection architecture preferably having fully integrated layers permitting inter-operability with adaptive applications and inter/intra-linking with external appliances and/or apparatuses. Optionally, the system may be utilized to perform extended information handling/processing, networking, personal assistance, industrial, commercial, medical, military, and/or security functions.
