Preh GmbH

Technologies for efficiently delivering power to electric vehicles, encompassing fast charging, wireless charging, and smart grid integration, alongside vehicle-side control and management of the charging process.

Designing user interfaces and interaction methods specifically for mobile or wearable devices, enabling control of external systems, monitoring user states, or facilitating real-world transactions.

Mechanical, electromagnetic, or hydraulic systems used to physically operate the contacts of a switch or circuit breaker, focusing on the linkages, motors, coils, or fluid dynamics involved.

Electronic, hydraulic, or steer-by-wire systems that precisely control vehicle direction, often incorporating feedback loops, compensation, and adaptation for various driving conditions or vehicle types.

Techniques for combining multiple materials or layers, often with specialized surface treatments, coatings, or assembly methods, to create functional or aesthetically enhanced plastic articles, including consumer goods and encapsulated electronics.

Layered glass or film structures designed to optimize optical (e.g., light transmission, reflection, diffusion) and/or thermal (e.g., insulation, heat reflection/absorption) performance in windows, displays, and lighting applications.

Methods and components for optimizing the performance, efficiency, and control of electric motors, inverters, and power converters within electric vehicle and hybrid vehicle drivetrains.

Innovations in the materials, manufacturing, and assembly of vehicle body components to enhance rigidity, crashworthiness, and functional integration.

Safety features built into or around vehicle seats to protect occupants during various accident scenarios, including airbags, pre-crash positioning, and blast attenuation.

Technologies that enable automated or mobile device-controlled access to a vehicle, including keyless entry, remote functions, and power-assisted steps or pedals designed to facilitate easier ingress and egress.

Specialized digital and mixed-signal circuits for controlling and reading out quantum bits (qubits), including generating precise modulated RF signals and integrating with photonic components for quantum operations.
