Title: The Innovations of Thomas Joseph Karpus
Introduction
Thomas Joseph Karpus is a notable inventor based in Apex, NC (US). He holds a total of 7 patents that showcase his contributions to technology, particularly in the fields of LED drivers and battery charging systems. His innovative work has made significant impacts in the industry.
Latest Patents
One of Karpus's latest patents is titled "Automatic dropout prevention in LED drivers." This invention provides a system and method for preventing a dropout of an LED current. The system includes a voltage source, a first circuit, a second circuit, a controller, and at least one LED. The first circuit receives a reference voltage from the voltage source and set-point current data from the controller to produce a threshold voltage. This threshold voltage is then converted into an output current by the second circuit, which compares it to an output voltage corresponding to the output current. The controller uses this information to determine if a dropout has occurred and adjusts the set-point current data accordingly.
Another significant patent is the "Method and apparatus for battery charging based on battery capacity and charging source constraints." This invention sets the charging current based on the battery's capacity or the constraints of the charging source. The termination current is set according to the battery's capacity, allowing for accurate detection of when charging should terminate, even if the charging current is limited by the source.
Career Highlights
Throughout his career, Karpus has worked with prominent companies such as Ericsson GmbH and Semtech Corporation. His experience in these organizations has contributed to his expertise in developing innovative solutions in electronics and energy management.
