Bombardier–Alstom HHP-8
The Bombardier–Alstom HHP-8 (High Horse Power 8000) is a type of twin-cab electric locomotive manufactured by a consortium of Bombardier Transportation and Alstom for use by Amtrak and the Maryland Area Regional Commuter system. The locomotive's electrical drive technology is directly derived from the SNCF BB 36000 manufactured by Alstom.
A small class size and reliability problems with correspondingly high per capita maintenance and replacement costs caused Amtrak to seek service replacements for its fifteen units at the same time as the older EMD AEM7s after only a decade in service.
Design
The locomotives have a 6 MJ crash energy absorbance structure; the carbody is stainless steel. The electrical traction system is directly derived from the system used on Alstom's BB 36000 Astride locomotives; this includes four 1.5MW three phase asynchronous traction motors powered by GTO based inverters, with one inverter per motor; the electric system also allows regenerative and rheostatic braking. The locomotives were designed for up to 217 km/h (135 mph) operation but are actually limited in service to FRA Tier 1 standards, operating up to 201 km/h (125 mph).

Hand Held Products
Hand Held Products was the world's largest manufacturer of linear and 2D handheld barcode scanners based on imaging technology. Its product range included rugged mobile computers, image kiosks, and barcode verification devices. Its range of data collection and communication products were designed for mobile, on-site, and transaction processing applications.
The company was created in a merger between the former Welch Allyn Data Collection, Inc. and Hand Held Products, Inc. in late 1999.
Welch Allyn Data Collection was formed in 1972 as a subsidiary of Welch Allyn, headquartered in Skaneateles Falls, New York, and by the 1990s was manufacturing a complete line of handheld bar code readers.
The original Hand Held Products company, established in 1981 in Charlotte, North Carolina, began life as a manufacturer of memory modules for Hewlett-Packard and Texas Instruments programmable calculators, but quickly came to the industry spotlight in 1983 thanks to an RFP hand-off by Hewett-Packard, as a package delivery company Federal Express selected their Micro-Wand portable data collection device to begin its first major proof of delivery system for package tracking.
