Title: Innovative Mind: The Contributions of Heinz-Dietmar Karl
Introduction
Heinz-Dietmar Karl, an accomplished inventor from Barntrup, Germany, holds three patents that reflect his expertise in developing innovative technologies. His work primarily focuses on advancements in function generators and circuit protection, showcasing his ability to blend theoretical engineering principles with practical applications.
Latest Patents
One of his notable patents is titled "Deriving rotational rate and angular position with a function generator." This invention outlines a method for determining the angular position and rotational rate of a function generator by first amplitude modulating a carrier oscillation to produce sine and cosine signals. These signals are then fed to opposite stator windings, inducing an analog function-generator signal in the rotor winding. This analog signal is subsequently converted into a digital format, leading to the derivation of a digital rotation-rate signal, which is then numerically integrated to obtain an angular-position signal. Interestingly, this angular-position signal is utilized to modulate the carrier oscillation, creating a feedback loop that enhances the system's performance.
Another significant patent by Karl is a "Circuit for protecting a switching transistor." This invention protects a switching transistor connected between a direct current voltage source and an inductive load, featuring a voltage-limiting element that activates the transistor when the source voltage surpasses a predetermined limit. The design includes elements that produce a control signal upon exceeding this limit and a variable pulse-width modulator that reduces pulse width when the source voltage rises too high, ensuring the transistor operates safely under various conditions.
