Solution Overview
Problem
Monolithic sensors with two or three connection contacts are inflexible and cannot be adapted to new interface standards, protocols, or algorithms for digital signal processing, limiting their ability to compensate for external disturbance variables.
Innovation Solution
A monolithic sensor arrangement with a freely programmable digital processor, program memory, and data memory, utilizing two connection contacts for supply voltage and data transmission, and a third contact for high-speed output, along with an integrated interface to demodulate clock and data from the supply voltage, enabling flexible adaptation to new standards and protocols through software changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a monolithic sensor uses hard-wired digital signal processing components and permanently installed external interfaces, then the device structure is simple and manufacturing is easier, but the sensor cannot be flexibly adapted to new interface standards and protocols
Solution Approach 1:
The patent applies the dynamics principle by replacing static hard-wired digital signal processing components with a freely programmable digital processor that can be dynamically reconfigured through software. This allows the sensor to adapt to new interface standards and protocols without physical hardware changes, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The patent implements parameter changes by using software-based configuration instead of fixed hardware wiring. The digital processor can change its operational parameters, interface protocols, and processing algorithms through software updates, enabling flexible adaptation while maintaining a simple physical device structure.
2Adaptability or versatility
If a monolithic sensor uses hard-wired digital signal processing components, then the manufacturing process is simpler, but new algorithms for digital signal processing and compensation cannot be tested and implemented
Solution Approach 1:
The patent applies dynamics by replacing fixed hardware algorithms with software-based digital signal processing. This allows new algorithms to be developed, tested, and implemented through software updates without requiring complex manufacturing processes or hardware reconfiguration, thus maintaining manufacturing simplicity while enabling algorithmic flexibility.
Solution Approach 2:
The patent uses copying by implementing digital signal processing algorithms in software form rather than hard-wired hardware. This software copy can be replicated, modified, and updated independently of the physical manufacturing process, allowing new algorithms to be implemented without complicating manufacturing while maintaining ease of production.

AI summary
The arrangement has a sensor (S) e.g. hall sensor, arranged in a housing (G), and two or three connecting contacts (C0, C1) provided at the housing for contacting the sensor. A freely programmable digital processor (CPU), a program memory (MP) and a data memory (MD) for controlling and/or processing the functionalities and/or measuring data of the sensor are integrated in the housing. A supply voltage and a pulse are inducible through the connecting contact (C1). An integrated interface (I) converts the serial data (d) from the connecting contacts as parallel data on a bus (B). An independent claim is also included for a method for actuating a monolithic sensor arrangement.
