Introduction

Christiane Henno is an inventor based in Tübingen, Germany, whose patent work includes innovations in light sensing and image-sensor operation. She is associated with Robert Bosch and has 3 patents.

Latest Patents

**Phototransistor Light Sensor Having a Feedback Arrangement.** This invention describes a light sensor designed for greater sensitivity and faster response. It combines a phototransistor with a source-follower transistor that converts impedance, and a second transistor that provides feedback between the phototransistor’s main electrode and control electrode.

**Image Sensor and Method of Operating an Image Sensor.** This invention addresses image-sensor decay time and supports higher image repetition rates. After a light sensor element records a signal representing light intensity and is reset, its output is initialized to a level selected according to the earlier signal before the next measurement.

Career Highlights

Henno’s listed patent work focuses on improving the performance of electronic sensing systems. The two described inventions address complementary challenges: increasing a phototransistor’s sensitivity and response speed, and reducing image-sensor decay time.

Collaborations

Henno is associated with Robert Bosch. Her listed coworkers include Roger Bauer and Stephan Mettler.

Conclusion

Christiane Henno’s patent portfolio reflects work on practical improvements to phototransistors and image sensors, with an emphasis on sensitivity, response speed, and faster image capture.
