One of his latest inventions is a hearing aid with a replaceable drying agent. This innovative device is designed to be worn in the ear and ear canal, featuring a replaceable container of desiccant material. The hearing aid includes a body that houses an electronic sound amplification circuit and a power source, such as a battery. The body is molded from plastic and custom-fitted to the user's ear. It also has at least one port that connects the interior of the body with the ear canal. The desiccant container is strategically mounted within the body to keep the ear canal moisture-free, thereby reducing irritation. This container is preferably associated with the battery, allowing both to be replaced simultaneously in a single operation.

Another significant invention by Clark is a device for selectively depressing a telephone switch. This device allows users to keep the flash button of a telephone handset depressed. It consists of a detachable member that engages with the handset, keeping the flash button pressed and the phone off the line. When the member is detached, the flash button is released, enabling phone calls. This device simplifies operation and eliminates the need to use the hook switch on the telephone cradle.
