Introduction

Jeffrey L Johnson is an accomplished inventor based in Fletcher, NC (US). He has made significant contributions to the field of sensor technology, holding two patents that showcase his innovative approach to modular devices.

Latest Patents

His latest patents include a Modular Sensor Device and a Modular Switch Device. The Modular Sensor Device is designed to supply analog data signals from temperature or pressure sensing elements. It connects to a modular switch system through a D-shaped sensor port in the modular switch housing. This design allows manufacturers and users to modify the standard modular switch system by applying and removing selected sensor modules. The interconnection between the sensor module and the modular switch system includes specific leads that carry both analog data signals and serial digital information signals. Additionally, the sensor module substrate is equipped with an amplifier, a reference voltage circuit, and non-volatile memory that contains calibration data for standardizing output signals from the sensors.

The Modular Switch Device features a housing that encloses an interconnected control module, a display module, and a power module. Similar to the sensor device, it allows users to connect electrical wires and power to the internal assembly through an opening. Users can select between AC and DC switched output modules, as well as the presence or absence of a 4-20 milliampere output module by plugging and unplugging them from designated wells in the housing. This modularity enables both manufacturers and users to customize the device to meet specific needs.
