Carlsbad is a rugged mobile tablet computer designed for police and emergency use. Carlsbad allows rich mobile data to be used over the Tetra radio network in the United Kingdom and Europe, going beyond text and audio transmission. A tablet computer, an antenna, a radio and input and output ports are enclosed in molded urethane plastic covers with an integrated rubber bumper. The screen measures 10.1 inches. Finger grooves and a nylon hand strap support comfortable use while walking, and the sculpted rear form fits the hand during long patrols.

- Production Technology
- The device integrates several internal components inside plastic covers: a tablet PC, antenna, radio, and io ports. Many of these are fully certified modules, allowing a more streamlined path to market since they don't need further certifications nor bespoke manufacture. Tetra Modem components were created specifically for this device. The plastic covers and buttons are rtv molded urethane plastic. The hand strap is nylon fabric.
- Design Challenge
- The creative challenge was creating a professional high-tech electronic device look, while maintaining fit-for-purpose functionality of a police or emergency device. Without care, the device could look overly functional and military. Carlsbad has a hand filling rear form, aided by a strap and side finger grips for comfortable in-hand use.
- Project Duration
- The project started in December 2010, in Bristol and Swindon, UK. The project was completed in April 2011 and went into limited production in June 2011.
- Operation Flow
- Carlsbad was designed for mobile, on-foot use. During a police patrol, the device would be used while walking and standing, while interacting with onscreen mobile data needs. It allows use of rich data, beyond what would be available on traditional text or audio Tetra radio transmission. In emergency situations, the device works on a government network, so it would not experience the same data overload issues as a public network.
- Research
- Carlsbad is the result of several previous tetra-tablet prototypes, created and evaluated in the field to allow the iteration into this device. Thin modern tablets were not durable enough, so additionally protective housing was added as rubber integrated into the form. Long use of a device carried in the hand was found to be uncomfortable, therefore forms were sculpted in clay to determine an ergonomic shape, then re-created in SolidWorks. To further increase positive grip, a hnad strap and finger grooves were incorporated in the form.
- Inspiration
- The Carlsbad tablet PC is the combination of 5 to 7 Tablet PCs aimed at the specific Market. The Carlsbad is a streamlined shape, made to feel comfortable in the hand and to not catch on clothing when in Mobile use. The integrated rubber bumper feature does not add bulky bumps nor give a military or power tool feel... rather it is a sleek form that presents as a high-end technological device. The overall form was created to fit comfortably in the hand while walking.
