Latest Patents

One of Ohta's latest inventions is a contactless power supply device designed for use with a handle and main body case. This device features a handle that can be attached and detached from a main body case, which partially covers an electric unit. The power transmission module protrudes from the main body case and includes a power transmission coil that is electrified based on the power supplied to the main body part. The handle houses a power reception module that faces the power transmission module when fixed to the main body case. This module has a power reception coil that receives power contactlessly via the power transmission coil. Additionally, a detection unit in the handle is driven by the power supplied through the power reception module and is designed to detect whether the handle is being gripped.

Another notable invention is a secondary coil module that receives electric power through a primary coil using a contactless power transfer technique. This module includes a core made of magnetic material, featuring a tubular portion and a bottom portion that closes one end of the tube. Inside the tubular portion, a storage battery is accommodated, which is charged by the power received via the primary coil. A coil winding is also disposed outside the core, adjacent to the bottom portion.
