IBM thinks thin
The new "ultraportable" Think-Pad 570 is a deceptively simple looking machine with a sleek black UltraCarbon casing, a derivative of the same carbon-fiber composites used in sporting goods equipment. And under its hood: an arsenal of computer luxuries.
When I first took it out of the box, it was the same size as my Compaq docking station laptop. But after a little "contact" engineering, I suddenly had two machines. The two-in-one notebook separates into a core unit of 3+ lbs with a 12-inch screen, full-sized keyboard with TrackPoint, integrated modem, and a bevy of features. The IBM UltraBase comes complete with a DVD drive, floppy drive, and speakers.
The ThinkPad 570 is designed to be a full-featured lightweight notebook. Measuring 9 x 11 x 1 inch, it comes with a generous amount of memory and hard-drive space, and enough ports (USB, IR, modem, two Type II slots, standard assortment) to connect to everything but the kitchen sink. The modular UltraBase can house a variety of drives as well as an extra battery. The built-in speakers may not do justice to a DVD movie, but they have more than enough volume for standard computer sounds. The base is hot-attachable to the ThinkPad, and brings the total weight up to a reasonable 7+ lbs.
A notebook system with two distinctly different configurations and multiple variations on both is often hard to set up, but IBM's setup program allows full access to power management, drive, and display options from a single easy-to-use interface.

Industry-standard Ethernet and TCP/IP technology, available in DVT Series 600 SmartImage Sensors and ORMEC's ORION™ family of motion controllers, simplifies vision-guided motion interfaces. Vision-system variables are mapped to a selection of Modbus TCP registers in DVT's FrameWork development software, while motion variables are mapped to the corresponding registers in ORMEC's MotionBASIC program development software. With the controller programmed to open a Modbus TCP connection as a client during operation and the DVT 600 powered up as a Modbus TCP data server, the controller can poll these registers at any time for the most recent inspection data. Using Ethernet TCP/IP is reportedly faster (10 mega-bits/sec) than serial communications, eliminates extra code for parsing and converting ASCII strings, and makes it easier to interface the motion controller to multiple sensors.

Maxon's electronically commutated (EC series) brushless pancake motors use ball bearings and have no mechanical brushes to wear out. The design reportedly offers long motor life, good heat dissipation, and high-overload capability because the coils are outside the rotor. Weighing 88g (3.1 oz), the motor's diameter is 43 mm (1.69 inch) while the length of the motor body (excluding shaft) is 16.3 mm (0.64 inch). Continuous output power is 12W, while maximum speed is 10,000 rpm. Ambient temperature range is -40 to 85C (-40 to 185F). Using electronic commutation minimizes electrical noise. Hall effect sensors are optional.

These one-piece flexures have equal OD and identical material, but they can exhibit different performance with the change of a single attribute, such as coil thickness, ID, or number of coils. This change can produce different torque, angularity (bending), parallel misalignment, torsional stiffness, and compression spring rate. The material can also be varied, providing many design options.
