Title: Ola Martin Sallenhag and Mobile Terminal Interface Innovations.

Introduction

Ola Martin Sallenhag is an inventor associated with Lund, Sweden, and Telefonaktiebolaget LM Ericsson. His patent work includes a mobile terminal interface designed to detect a phone’s flip position and support accessory controls through existing signal connections.

Latest Patents

Sallenhag is credited with 1 patent. His patent, “Mobile Terminal Interface,” describes using the microphone’s power-supply circuit to determine whether a mobile phone’s flip portion is open or closed. The terminal can detect the circuit’s state by measuring current flow or a voltage drop across a supply resistor.

The invention also describes enabling an on-hook/off-hook button on a hands-free accessory without adding signal lines. A switch in the microphone signal line can create an interruption that the terminal detects as an off-hook condition. The interface is further designed to support digital or analog signaling with no increase in the number of pins or signal lines.

Career Highlights

Sallenhag’s documented patent contribution focuses on mobile-terminal circuitry and accessory interfaces. The design combines flip-position detection, hands-free call control, and flexible signaling within existing connections.

Collaborations

His listed coworkers include Heino Jean Wendelrup and Lars Engelin. The patent is associated with Telefonaktiebolaget LM Ericsson.

Conclusion

Ola Martin Sallenhag’s patent illustrates an approach to making mobile phones and accessories more capable by using existing circuitry and connections efficiently.
