Title: The Innovative Contributions of David B. Rank

Introduction

David B. Rank is a notable inventor based in Waukesha, WI (US). He has made significant contributions to the field of sensor technology, holding a total of 3 patents. His work primarily focuses on developing sensors that enhance safety and functionality in various applications.

Latest Patents

One of his latest inventions is the adaptable tip sensor. This device is designed to detect the angular tipping of an object relative to a selected frame of reference. The sensor features a case that defines a two-dimensional straight-sided V-groove, allowing a disk to roll within it. A sensing device detects whether the disk is present in the apex of the V-groove. If the object remains upright, the disk stays in place, and the sensor produces a first signal. However, if the object tips beyond a predetermined angle, the disk rolls out, triggering a different signal. Additionally, fluid within the case dampens spurious vibrations, while a labyrinth and air bubble enhance the desired rolling of the disk when tipping occurs.

Another significant invention is the rotational speed/tip sensor, which combines both a tip sensor and a speed sensor into a compact unit suitable for motorcycles. This sensor operates similarly to the adaptable tip sensor, detecting the presence of a disk in the V-groove apex. If the motorcycle tips over, the disk rolls out, activating the tip sensing device to open a circuit through the speed sensing device, ultimately shutting down the motorcycle engine. This innovative design uses only three wires to connect both sensors to the engine control.
