I do not believe you are correct in attributing the invention of the safety lamp to Elisha Otis, it was Sir Humphry Davy who did that (hence the name the "Davy Lamp").
However, Elisha Otis was an inventive genius and his most famous invention is the safety device that prevents elevators from falling if the hoisting cable fails. (aka "Otis Lifts").
I have made a link for you to follow explaining what he did.

To use a Blue Point amp clamp, first, set the clamp to the appropriate mode for measuring either AC or DC current. Open the clamp and position it around a single conductor, ensuring it doesn't touch any other wires. Then, read the current measurement on the display. Always ensure that you're following safety protocols and the manufacturer's instructions for accurate and safe operation.
The author advises connecting the jumper cables in a specific order to ensure safety and effectiveness. First, attach one red clamp to the positive terminal of the dead battery, then the other red clamp to the positive terminal of the working battery. Next, connect one black clamp to the negative terminal of the working battery and finally attach the other black clamp to an unpainted metal surface on the dead vehicle. This method helps prevent sparks and potential damage to the vehicles.
He didn't invent anything he was a bacteriologist.
Jesus understood Elisha's healing of Naaman as prefiguring that He Himself would also be sent to other nations. The point of His reference to Elijah and Elisha is that they had been sent to Gentiles, not to Israelites-a hint of His own mission.
Measures current by magnetic field induced into the clamp. You need to clamp a single conductor. For example you couldn't just clamp a lamp cord since it has two conductors and the current is going in opposite directions and the fields cancel each other out.
clamp can be a noun - as a noun it means a device or tool to hold things egThe clamp holds the side together.Clamp can also be a verb - as a verb it means to use a clamp or some other tool to hold something down or together egI clamp the sides together before I nail them.
A clamp meter is an electrical measuring instrument used to measure current flowing through a conductor without needing to make direct contact or disconnect the circuit. It features jaws that clamp around the wire, allowing it to measure alternating current (AC) or direct current (DC) through magnetic induction. Clamp meters are commonly used by electricians and technicians for troubleshooting and monitoring electrical systems due to their convenience and safety. Additionally, many models also measure voltage, resistance, and other electrical parameters.

Rich Stachowski is known for inventing the "Guardian Angel," which is a safety device designed for motorcyclists. It uses a combination of sensors and lights to enhance visibility and alert other drivers, aiming to reduce accidents and increase rider safety. His invention focuses on improving communication between motorcyclists and other road users.

A utility clamp is spring-loaded open-jaw clamp that can be tightened down to hold something securely in place. They are commonly made with three prongs (two on one side and one on the other), or with two rounded prongs, with one on each side. They are commonly used to hold laboratory glassware, such as erlenmeyer flasks, distillation flasks, glass tubing, round bottom flasks, thermometers, etc. Utility clamps have a long rod attached to the clamping part that allows it's position to be carefully adjusted by using a clamp holder, which is described below.A clamp holder is used to secure an extension-type utility clamp to a support stand (or ring stand). Sometimes it's used to clamp a couple of support rods together, or to clamp an iron ring or other attachment to a metal bar.See the Web Links and Related Questions for more information and pictures of a utility clamp and a clamp holder.
