Society News
The next IEEE Signal Processing Society meeting will be held in two locations on September 27th and 28th. The meeting on the 27th begins at 4:00pm at CSU in Ft. Collins. The meeting on the 28th begins at 6:00pm at Raytheon in Aurora.  The topic is Exact Particle Flow for Nonlinear Filters by Fred Daum.  For more information, to sign up, and to get directions, visit the IEEE SPS website.
Electric Vehicle Workshop
On September 25th, the IEEE will be presenting a workshop on electric vehicles at CU Boulder.  On display will be:
  • Tesla Sports Car
  • Boulder Electric Utility Van
  • Toyota; both a Prius Hybrid and a Prius Plugin
  • Hyek Chevrolet Hybrid
  • Honda Insight Plugin
  • Nissan

Li-ION Batteries On the Move

Lithium-ion batteries continue to improve in all respects: Capacity, charge rate, cost, and safety.

Safety has been a vexing issue, since failure of these types of batteries can be dangerous. This concern, as well as the cost, has been limiting the wide-spread adoption of this technology in electric vehicles. That is changing.

A promising trend is toward Lithium Titanate batteries. This technology has made great strides in resolving many of the issues common to other types of Li-ION batteries. They can be charged very quickly (at a rate of 50C for example). According to one manufacturer: In testing, a 35 kWh battery pack was charged in ten minutes. They also provide advantages in longer life with up to 25,000 deep cycles, higher power density than other nanostructured cells, wider operating temperatures, and most importantly, greater stability under electrical and mechanical stress (it is said that the cells cannot catch fire). Naturally, they are also more expensive.

The advances don't just apply to the automotive industry. If the trend continues, in the near future, we may be designing circuits powered by Li-ION clothing.
If you would like help developing a new product or if you find your project understaffed, CEPD can help you meet your deadlines. Our staff draws on years of diverse product design experience to provide creative and timely solutions for your product needs. Some of our specialties include:
  • DSP
  • Embedded Systems Hardware and Software
  • Data Acquisition
  • Wireless Sensor and Telemetry Systems (Zigbee, Cellular, VHF, Bluetooth, ANT+, etc.)
  • Control Systems
  • Programmable Logic: FPGA / CPLD / EPLD
  • Analog Circuit Design
  • Switching Power Supply Design
  • Battery charging (all chemistries)
  • PCB Design and Layout
  • Analysis and Documentation
Our goal is to provide cost effective and expedient design options for our clients. Our services range from an hour of consultation to large turn-key product development projects. We provide detailed proposals, accurate estimates and time schedules to help you manage each phase of the project. We can offer fixed cost or time and materials proposals to suit your specific needs. There is no cost to you for the initial proposal we create and the initial discussion required!
