Title: The Innovations of John J McSheffrey
Introduction
John J McSheffrey is a notable inventor based in Hingham, MA (US), recognized for his contributions to technology and engineering. With a total of 17 patents to his name, he has made significant advancements in power management systems and pressure monitoring technologies.
Latest Patents
One of his latest patents is a power management system for pressure monitoring. This innovative system includes a normally-open switch, an on/off circuit, a microprocessor, and at least one sensor to monitor a condition. The on/off circuit features an on/off control gate-controlled switch device, such as a PMOS device for system power. It also includes a flip/flop switch to activate and deactivate the on/off control PMOS device, along with a transition detection circuit connected to the normally-open switch. The system is powered by a single DC power source, which establishes a source voltage to power the on/off circuit and the normally-open switch. The transition detection circuit generates an 'on' signal when the user activates the normally-open switch, supplying this signal to the flip/flop switch to change it to an “on” state. While activated, the on/off control PMOS device enables system power from the power source to be provided to the sensor and the microprocessor. The microprocessor generates an “off” signal when the normally-open switch is activated for a selected period, supplying this signal to the flip/flop switch to deactivate the on/off control PMOS device, thereby disabling system power to the sensor and the microprocessor.
Career Highlights
Throughout his career, John has worked with various companies, including Mija Industries, Inc. and En-gauge, Inc. His work has significantly impacted the fields of power management and pressure monitoring.
