Data Privacy Technique Discussed at IEEE Distinguished Lecture Series

If you’d like to send a private Valentine to that special someone this month, Spatial Digital Systems can help.

The Agoura Hills-based company has come up with a technique to embed your message within a separate, innocuous message to shield it from prying eyes. Donald Chang, Spatial Digital Systems’ CEO and President, demonstrated the technique before faculty and students at the IEEE Systems’ Council’s IEEE Distinguished Lecture Friday.

Called “digital enveloping,” the technique can be used to wrap a Microsoft Word document in an audio file or a real-time voice recording in an audio file. Sender and receiver would both know the technique was being used.

In Friday’s demo, the company used audio files of Chinese opera to envelop the actual message. “Like in the marketplace, there’s a lot of noise,” said Spatial Digital Senior Engineer Joe Lee. “You would not suspect there’s a message hiding inside.”

The technique could be useful for ensuring better privacy protection for data in the cloud. As the company describes it, digital enveloping relates to “transforming” an information data stream with a digital envelope stream concurrently into a multi-dimensional data structure via Wavefront multiplexing (WF muxing, K-muxing).

Top priorities are the appearance of the enveloped data and the reliability of the enclosed information data. The transformation is mathematically identical to the function of a beamforming network (BFN) for a multibeam phased array.

Spatial Digital Systems was formed in 2002 to develop smart antenna technologies for wireless communications. Chang is an expert on communications satellites, advanced satellite antennas, space-based microwave remote sensing instruments, especially in passive synthetic aperture radiometry. He has authored more than 40 technical papers, holds more than 100 U.S. patents, and has more than 50 U.S. patents pending on smart antennas, low cost spacecraft design, and satellite constellations for multimedia applications.

Chang was the recipient of Hughes’ Hyland Award in 2000 for key contributions in digital beam-forming technology. He holds a PhD and MSEE from Stanford University.

MAE Team Preps Remote-Controlled ‘Nutcracker Box’ for Its Stage Debut

Each year, Long Beach Ballet Artistic Director David Wilcox tries to add some new crowd pleaser to his production of “The Nutcracker”—be it a flying sleigh, a white stallion, on-stage pyrotechnics, or a tree growing before your eyes.

This year, for the company’s 35th annual production of the popular Christmas classic, the extra pizzazz will be supplied by a box created by a team of students led by Long Beach State Mechanical Engineering Associate Professor Chris Beyer.

But it’s not just any old box. This 7-foot cube is remote-controlled, produces clouds of steam, and is mechanized to let the Nutcracker prince pop from the top at just the right moment. Continue reading

Caltrans Testers Test Out New Construction Materials Program

They usually test construction materials. But this week, two dozen Caltrans and industry technicians from throughout the state were at Cal State Long Beach to test out a new program to increase quality and reduce delays on construction projects.

Supported by a $1.3 million interagency agreement with Caltrans, and implemented by CSULB, the Joint Training & Certification Program (JTCP) will deliver training and certification for materials testing technicians in the specialties of Hot-Mix Asphalt, Soils and Aggregates, and Portland Cement Concrete.

Asphalt for testingThis week’s two-day pilot class, a combination of seminar and lab, was intended to iron out any wrinkles before the first classes begin early next year. “I hope you have a great experience,” principal investigator Shadi Saadeh, a CSULB civil engineering associate professor, told the testers. “I really appreciate the time you’ve taken to offer your feedback.” Continue reading

Biomedical Engineering Department Takes Interdisciplinary Approach

The College of Engineering Thursday celebrated the launch of a new department in the fast-growing field of Biomedical Engineering.

With the introduction of the Bachelor of Science in Biomedical Engineering, CSULB becomes the only CSU in Southern California to offer a standalone degree in this area. Biomedical Engineering graduates will be able to apply their engineering, biology, bioinformatics, and biomechanical knowledge to create artificial organs, prostheses, medical instruments, healthcare management and delivery systems, and more.

“I’m really thankful to the committee that worked tirelessly to develop the curriculum,” said College of Engineering Dean Forouzan Golshani. Continue reading

MAE Department Salutes Its Alumni, Volunteers, and Graduates

CSULB Mechanical and Aerospace students on Monday gathered with faculty and advisors for a celebration before their graduation.

Xerox VP Arnold Hackett Named CECS Distinguished Alumni

Arnold Hackett was one of nine children raised by a single parent. He is now vice president of alliance and partnership management at Xerox.

The 2001 CSULB computer science graduate said he has Xerox to thank—and also CSULB. “They helped me become what I am today,” he told students at the CECS Department Graduation.

Hackett, who earned his master’s in computer science while working at Xerox, on Monday received the CECS Distinguished Alumni Award. He was also named the Alumni Association’s College of Engineering 2017 Distinguished Alumni Award.

Hackett said a degree in computing is very powerful. “You’ve been given the tools to create and innovate and make your dreams a reality,” he said. Continue reading

Students Show off Design Projects

Some teams had their Senior Design Projects ready to demonstrate hours in advance. But for others, Friday morning was crunch time.

CSULB students enrolled in the two-semester Senior Design Project class (MAE 471/472) have an opportunity to learn about design, manufacturing, collaboration and more.

This year, 128 students worked on 26 projects. The capstone course, taught by Associate Professor Christiane Beyer, emphasizes the theory and practice of modern design and manufacturing.

Focusing on concept design and embodiment design in the first semester, the course culminates in project implementation during the second semester.

The rigorous course teaches systematic design methods and tools combined with the application of CAD/CAE/CAM software and modern manufacturing tools.
