Title: The Innovative Contributions of Jeffrey L. Sajna

Introduction

Jeffrey L. Sajna is a notable inventor based in St. Charles, IL (US). He has made significant contributions to the field of technology, particularly in sensor design and rotary inductive coupling. With a total of 3 patents to his name, his work reflects a commitment to enhancing signal response and efficiency in various applications.

Latest Patents

One of Sajna's latest patents is a sensor designed for increasing signal response time. This innovative sensor employs a resiliently deflectable member along with a pressure-sensitive signal element and a base member. The dampening effect of the elastic material provides a longer signal response time, allowing sufficient time for a system to react without the need for additional signal conditioning circuitry. The sensor is capable of sensing a selected path of movement for a moveable element and establishes a signal indicative thereof. Additionally, the limit sensor includes a resiliently deflectable member that activates the signal at a predetermined station along the preselected path of movement. An actuator receives the force from the moveable element and transfers it to the pressure-sensitive signal element. In the preferred embodiment, the resiliently deflectable member includes a leaf spring positioned between the actuator and the pressure-sensitive signal element.

Another significant patent by Sajna involves a rotary transformer that features a stator and rotor, each formed by winding a coil on a non-magnetic bobbin. This design is overmolded with magnetically permeable particulate material dispersed in a non-magnetic medium, which is preferably selected from thermoplastic, thermosetting plastic, and thermoplastic elastomer.
