The article focuses on the digital camera R707 from Hewlett-Packard Co. (HP). The company has a team that focuses specifically on the mechanical or industrial design and a second team that works on the electronics. What makes a design like this one especially tricky is that the mechanics play a key role in its operation, particularly with respect to the lens, which contains some precise moving parts. The camera's lens subsystem is designed by a lens manufacturer, which comes up with a custom design to meet the HP specs. That subsystem contains all the mechanisms to do zoom, focus and aperture. What's not included is the control system that runs the lens, which is embedded in the HP-authored firmware. That is part of what HP calls its "special sauce." The camera's internal memory features 32 Megabytes that are available to the user to store photos. That makes the camera usable, even if there's no memory card installed. On SD as the memory card of choice in the R707 there are so many formats available that it's a real challenge for both the company and the consumer.
