Silly App Attracts Attention Based on Cable Show Popularity

A Carnegie Mellon University computer science student has created an application with a singular purpose: letting users “Hodor” their friends. Hodor, a well-known character on the HBO cable series Game of Thrones is capable of saying only his name. Tyler Hedrick a software engineer at the Medium social-networking site, created the Yo, Hodor app for iOS devices. The app lets users send an audio message of Hodor saying his name to recipients who have also signed up as participants. It is similar to, but not based on, Yo, a novelty app that texts the word “Yo” and that has attracted $1.5 million in investment. (PC Mag)(Gizmodo)(Tech Crunch)(iTunes Store)

Judge Awards Carnegie Mellon $1.54 Billion in Patent Infringement Case

A US federal judge has ordered Marvell Technology Group to pay Carnegie Mellon University (CMU) $1.54 billion for infringing two hard-drive patents that the school owns. This is 41 percent of the maximum $3.75 billion award the university sought. The jury originally awarded CMU $1.17 billion in December 2012 for damages and another $79.6 million awarded for alleged infringements the jury did not consider as they lacked recent financial information. The court rejected the triple damages the university sought as well as the university’s request that further sales of goods containing the infringing technologies be blocked. At issue are two US patents related to the accuracy with which circuits in a hard drive read data from a high-speed magnetic disk granted to the university in 2001 and 2002. Carnegie Mellon says that Marvell sold at least nine different circuit devices that incorporated the patented technology, ultimately selling billions of chips. CMU has not yet commented on the court ruling. Marvell said it plans to appeal, claiming the school’s patents were invalid. The company also contends the court’s damages assessment was wrong.

Judge Denies Marvell Request to Reduce Jury Award

A US federal judge has denied a request by Marvell Technology Group to cut $620 million of a $1.17 billion jury verdict against the company for patent infringement. This was reportedly the third greatest US patent-infringement penalty since 1995. A jury found that Marvell infringed on two Carnegie Mellon University (CMU) patents for technologies designed to improve the accuracy with which hard-drive circuits read data from high-speed magnetic disks. . The company asked the court to reduce the resulting penalty, saying the university “unreasonably delayed pursuing its claims for patent infringement,” according to Reuters. The CMU researchers developed their technology between 1995 and 1998, applied for patents in 1998, and received them in 2001 and 2002. Marvell worked on the technology that was the subject of the lawsuit between 2001 and 2003. CMU, which owns the patents, filed suit in March 2009, claiming at least nine of the company’s devices used the patents without licensing. The court found Marvell earned $10.34 billion in revenue and $5.05 billion in profit by using the university’s patents. US District Judge Nora Barry Fischer said Marvell willfully infringed the patents, making the $1.17 billion award potentially subject to being trebled by the court.

New Method Detects Software Bugs in Surgical Robots

Carnegie Mellon University and Johns Hopkins University researchers have developed methods for both reliably detecting software bugs and formally verifying software used by surgical robots. They used their methods to find a safety flaw that could potentially injure a patient in a control algorithm for a robot designed to assist in skull surgery. The scientists say their findings could potentially change how robotic surgical devices are evaluated to insure operational safety. Today, most systems rely on testing, which does not adequately cover all the potential circumstances to which a system might be exposed in the operating theater. The researchers are scheduled to present their work at the Hybrid Systems: Computation and Control conference in Philadelphia this week. (EurekAlert)(Carnegie Mellon University)

DARPA Creating Robotic Hands

DARPA, which is conducting numerous robotics-related projects designed to aid US soldiers in the field, has created a low-cost robotic hand. The latest work by its Autonomous Robotic Manipulation program is a step toward creating robots with dexterous hands. The agency designed its new device to cost $3,000. A robot was able to use the new hand to change a tire by itself. The new hands could be key to developing robots able to operate autonomously in the field on tasks such as finding and defusing improvised explosive devices or inspecting suspicious packages. DARPA is collaborating with researchers from iRobot, the US Sandia National Laboratory, the University of Southern California, Carnegie Mellon University, and NASA to create a robotic arm with multifingered hands.

Collaboration Tool Tracks Project Tasks

A Carnegie Mellon University (CMU) researcher has designed a tool that helps managers assign and track tasks in collaborative projects. The Pipeline tool makes it easier for project leaders to delegate and redistribute leadership responsibilities on collaborative projects and also streamline the project-development process. Kurt Luther, now a postdoctoral fellow at CMU’s Human-Computer Interaction Institute created the open-source tool while a doctoral student at Georgia Institute of Technology. He presented his research at the recent ACM Conference on Computer Supported Cooperative Work and Social Computing (CSCW 2013) in San Antonio, Texas. (PhysOrg)(Carnegie Mellon University)(Pipeline)

New Biometrics Technologies Measure the Human Gait

A newly created Carnegie Mellon University lab is working on technologies that could monitor or secure access to facilities such as nuclear power plants or military bases. The CMU Pedo-Biometrics Lab is working on gait-based biometrics. The system would work by incorporating a device into a subject’s insole to measure factors such as gait and foot pressure. It would then compare the stored measurements for authorized personnel to those of people trying to enter a secure facility. When the patterns don’t match, a wireless alarm sounds. The CMU researchers are working with Autonomous ID to develop a low cost, accurate system able to work across a range of body types. The technology could be useful in other settings, such as an application detecting gait changes that could signal the early stages of dementia.

Academic Researchers Create Bubble-Based Display

Scientists have developed what they claim is the world’s thinnest screen. They made the display from a soap bubble-like material on which they can project either flat or 3D images. The researchers—from the University of Tokyo, Carnegie Mellon University, and the University of Tsukuba—used ultrasonic sound waves emitted from speakers to alter the surface of a bubble made from colloidal materials, those in which one substance is microscopically dispersed evenly throughout another. The material is difficult to puncture and thus, users can interact directly with it. The concept is based on the dynamic bidirectional reflectance distribution function, which defines how light is reflected at an opaque surface. The researchers say multiple membrane-based screens could be used in combination, such as for museums or exhibitions because the novel, spherical displays would attract viewers. They will demonstrate their technology at SIGGRAPH 2012, to be held in Los Angeles 5 through 9 August. (PhysOrg)(SIGGRAPH 2012)
