Vehicle Solutions
Grayhill develops user interface devices and control components for vehicles and mobile machinery where reliability, ergonomics, and precise control are critical. The solutions are designed for seamless communication via CAN bus (J1939 and CANopen) and easy integration with onboard vehicle control systems.
With a strong focus on both functionality and user experience, Grayhill designs components that improve operator efficiency, reduce fatigue, and simplify installation for original equipment manufacturers (OEMs). The products are built for harsh environments and withstand vibration, dirt, moisture, and exposure to chemicals.
Typical applications
- Operator seats and armrest controls in construction and work vehicles
- Control panels and operator interfaces for agricultural and off-highway machinery
- Control systems for excavators, pavers, rollers, and specialty vehicles
Example solutions and products
- CAN bus keypads for reliable and flexible system control
- Rotary encoders (mechanical, optical, and Hall-effect) for accurate position feedback
- Joysticks and control handles for precise and ergonomic machine operation
- Displays for diagnostics and operational data
Grayhill offers both standard products and custom-engineered solutions, enabling fast development from prototype to full-scale production.
Healthcare solutions
In medical technology applications, precision, hygiene and reliability are crucial. With a deep understanding of how doctors, nurses, and technicians interact with medical equipment, Grayhill focuses on providing clear tactile and audible feedback, enabling confident and intuitive operation in critical situations.
The products are designed with sealed, smooth, and easy-to-clean surfaces, minimizing crevices where bacteria can grow. Carefully selected materials withstand frequent cleaning and exposure to harsh disinfectants commonly used in healthcare environments.
Typical applications
- Ultrasound and diagnostic imaging systems
- CT scanners and radiology equipment
- Patient transport and hospital bed systems
- Medical control panels and operator interfaces
Example solutions and products
- Rotary encoders and multifunction joysticks with precise haptic feedback
- Sealed keypads and button assemblies for long service life and high reliability
- Touchpads and displays optimized for medical use
- Complete front panels and HMI solutions, including electronics, firmware, and enclosures
Grayhill offers both standard components and custom-engineered HMI solutions, ranging from individual input devices to fully integrated control panels—designed to meet stringent requirements for safety, cleanliness, and usability.
Military solutions
Grayhill develops and manufactures rugged, operator-centric human-machine interface (HMI) components for military and defense applications, where reliability, precision, and situational control are critical. With over 80 years of experience, Grayhill is AS9100 Rev D certified, ITAR compliant, and designs products that meet MIL‑STD-810, MIL‑STD-461, and MIL‑STD-3009 standards.
Human-in-the-Loop for AI and Autonomous Systems
As AI and autonomous technologies reshape defense operations, the human operator remains essential—especially in mission-critical applications where control, oversight, and safety cannot be compromised. Grayhill applies Human-in-the-Loop (HITL) principles to its HMI components, ensuring operators maintain engagement, situational awareness, and accountability even in AI-enabled or semi-autonomous systems.
Typical applications
- Weapon sights, laser systems, and tactical communications
- Handheld soldier terminals and GPS devices
- Crew-served vehicles and unmanned robotic platforms
- AI-enabled or autonomous military systems requiring operator oversight
Example solutions and products
- Sealed rotary switches and mechanical/optical encoders with tactile feedback
- Rugged keypads, pushbuttons, and touch interfaces
- Custom enclosures and HMI panels designed for extreme environments
- NVIS-compliant backlighting for night vision operations
Grayhill’s HITL-focused interfaces combine robust hardware with intuitive, operator-friendly design, providing reliable control in high-stakes environments. From dismounted soldiers to vehicle-mounted systems, Grayhill delivers interfaces that balance autonomy with human judgment, ethical responsibility, and operational performance.
