Title: The Innovations of Erik Johnson
Introduction
Erik Johnson is a notable inventor based in Philadelphia, PA. He has made significant contributions to the field of hazard alarm technology, holding a total of 5 patents. His work focuses on enhancing the functionality and reliability of carbon monoxide alarms and other hazard detection systems.
Latest Patents
One of Erik's latest patents is for a carbon monoxide alarm supervision system. This innovation involves the supervision and testing of a carbon monoxide (CO) alarm using an application-specific integrated circuit (ASIC) and microcontroller. The design isolates an electrochemical CO sensor from its detection circuit, allowing for a voltage charge change. The CO sensor is then reconnected to the detection circuit, and over time, the voltage charge returns to an equilibrium state. This process enables a determination of whether the CO sensor and detection circuit are functioning properly based on voltage versus time results.
Another significant patent is for temporal horn pattern synchronization. This invention connects multiple hazard alarm devices located in diverse spatial positions through an input-output bus. An interconnect protocol allows non-originating alarm devices to synchronize their audible alert tone pulses with those from an originating alarm device during a local hazard alarm condition. This ensures that all audible alert tone pulses sound together, accommodating for signal contention and arbitration among the spatially diverse alarm devices.
Career Highlights
Throughout his career, Erik has worked with prominent companies such as Microchip Technology Inc. and Wheelock, Inc. His experience in these organizations has contributed to his expertise in developing innovative alarm systems.
