A mobile internet of things (IoT) unit for cleaning grease vents, herein referred to as the unit, is disclosed. The unit is comprised of the following parts: a mobile platform with magnetic tracks; a mobile device software application (app); cleaning attachments such as power washers and lasers, sensors such as conductivity meters (to measure buildup), air temperature, velocity and pressure; recording devices such as digital still and streaming cameras; a microcontroller with wireless communications; onboard lighting and a rechargeable battery. Additional details regarding the unit are examined further in this disclosure.

An unmanned device for a marine environment comprises a location sensor configured to gather location data corresponding to the unmanned device; at least one propulsion system; a transmitter and memory including computer program code. The computer program code is configured to, when executed, cause the processor to cause the propulsion system to propel the unmanned device in a pattern along the body of water, cause the sonar transducer to emit the one or more sonar beams into the body of water, receive sonar return data corresponding to sonar returns, and generate a sonar image corresponding to the sonar return data. Further, the computer program code is configured to cause the processor to detect an object within the sonar image, assign a score to the object indicating the likelihood that the object is a desired object type, and send an alert to the remote electronics device upon assignment of the score.

A vehicle includes a frame, a drivetrain coupled to the frame, a base assembly coupled to the frame, and a lifting implement coupled to and supported on the base assembly. The lifting implement includes a platform, a cradle rotatably coupled to and supported on the platform so that the cradle, a scissor assembly coupled between the platform and the base assembly, and a lift actuator coupled between the base assembly and the scissor assembly. The lift actuator is configured to selectively raise the cradle relative to the base assembly. The lift actuator is a multi-stage telescoping actuator that includes a base stage, an intermediate stage, and an outer stage. The base stage is coupled to the base assembly, the outer stage is coupled to the scissor assembly, and the intermediate stage is arranged between the base stage and the outer stage.
