2010 Create the Future Design Contest Medical Category Winner

(Winner of an HP Workstation) IDEA Enhanced Pulse Oximetry Rodrigo Teixeira, Alton Reich, and Stephen MalinHuntsville, AL Stroke volume, or how much volume of blood the heart pumps with each beat, demonstrates the organ’s efficiency and health, but the performance is often measured invasively using a Swan-Ganz catheter or ultrasound echocardiography. IDEA Enhanced Pulse Oximetry technology, however, measures light absorption by blood as it pulses. By analyzing the light pulses’ shape and evolutions, the technology gathers information about the patient’s cardiovascular system, including stroke volume and cardiac output. The Intelligent Data Extraction Algorithm, or IDEATM, analyzes noisy pulse signals and interprets them in a real-time physiological context.

2010 Create the Future Design Contest Safety and Security Category Winner

(Winner of an HP Workstation) Digital Window Distributed Imaging Camera Ellen Cargill, Peter Jones, and Dennis PurcellBoston, MA Scallop Imaging’s seven-megapixel Digital Window D7-180 video surveillance camera streams and records in full-color high resolution throughout a 180° field of view. The standalone device acts as a potential alternative to a set of several traditional cameras, which have a smaller field of view and often use slower pan/tilt/zoom mechanisms to pinpoint a target.

2010 Create the Future Design Contest Transportation Category Winner

(Winner of an HP Workstation) Regenerative Braking Bike Front Wheel David Swain, Frank Maurer, Jason Moore, and Albert ShihAnn Arbor, MI With the push of a button and without any pedalling or external energy, a regenerative front wheel can bring a bicycle back to its previous speed after a rider has hit the brakes. Non-spinning hydraulics, which are located in the center of the wheel, store braking and hill energy for later release.

2010 Create the Future Design Contest Sustainable Technologies Category Winner

(Winner of an HP Workstation) Sustainable, Durable Bridges of the Future Ibrahim Al-KhattatTalacre, Wales, United Kingdom Alight, pre-stressed, segmented-arch (LPSA) bridge-building system uses a kit of compact parts that can be manufactured and transported, resulting in cost, energy, and capital investment savings. In addition to providing an alternative to heavier energy-consuming bridge materials like concrete and steel, the framework’s design flexibility helps to withstand natural disasters like earthquakes.

Laser Beam Profiling

What You Need to Know to Do It RightMost people working with lasers today are trying to do something with the light beam, either as the raw beam or, more commonly, modified with optics. Whether it is printing a label on a part, welding a precision joint or repairing a retina, it is important to understand the nature of the laser beam and its performance. Laser beam profiling provides the tools to characterize the laser and know precisely what the beam is doing at the point of the work and if the optics are having the desired effect. Lasers and laser applications come in many varieties, varying in power density, wavelength, depth-of-focus, beam size, pulse duration and myriad other parameters. It is this variety that makes lasers so useful for interacting with and manipulating many different materials and media. But, it is also this variety that adds complexity to the beam profiling process.
