- Flying robots made from cellophane?
- Researchers have discovered that ordinary cellulose is a piezoelectric and smart material that can flap when exposed to an electric field. ScienceNOW reports that electricity can give life to cellophane. When you put a very thin layer of gold on each side of cellophane, and that you apply electric current...

- Intelligent side-impact protection for cars
- European researchers have developed a car body that thinks intelligently and protects its occupants before a side-impact. These future cars will be equipped with radar sensors and cameras integrated in the doors. If another car is about to collide with your own vehicle, the system will detect it 200 milliseconds...

- Fuzzy Logic Control Based QoS Management in Wireless Sensor/Actuator Networks
- Wireless Sensor/Actuator Networks WSANs are emerging rapidly as a new generation of sensor networks. Despite intensive research in Wireless Sensor Networks WSNs, limited work has been found in the open literature in the field of WSANs. In particular, Quality-of-Service QoS management in WSANs remains an important issue yet to be...

- Western Digital 'GreenPower" drive halves power consumption
- The Western Digital "GreenPower" WD10EACS 1 terabyte hard drive is one the cheapest hard drives you can buy at this capacity ($300 including shipping) but it's also the most energy efficient. The drive has a technical specification of 4 watt idle which I measured fluctuating between...

- Wireless Sensor/Actuator Network Design for Mobile Control Applications
- Wireless Sensor/Actuator Networks WSANs are emerging as a new generation of sensor networks. Serving as the backbone of control applications, WSANs will enable an unprecedented degree of distributed and mobile control. However, the unreliability of wireless communications and the real-time requirements of control applications raise great challenges for WSAN design....

- That damned recessed iPhone headphone jack
- I don't know what Apple was thinking when they released the iPhone with a recessed headphone jack that prevents customers from using almost any set of earphones or earbuds that they already own. Surely someone mentioned this little fact in the beta testing? Focus groups? Oh yeah,...

- WD's surprising little drive
- IIRC, it was just 15 years ago that Maxtor shipped the first 1 GB, 3.5" drive. The usual things happened: database admins all swore it was "too big," techies said it cost too much, and regular users wondered if they could ever fill it up.DBA's still kvetch about disk size...

- Making sense of "mean time to failure" (MTTF)
- Last week researchers at Carnegie Mellon University published a paper which examined the real-world reliability of hard drives. It concluded that hard drive failure rate was much higher by a factor of about fifteen times higher than that expected based on mean time to failure MTTF information supplied by...

- Dual-Stage Servo Systems and Vibration Compensation in Computer Hard Disk Drives
- This paper discusses two mechatronic innovations in magnetic hard disk drive servo systems, which may have to be deployed in the near future, in order to sustain the continuing 60% annual increase in storage density of these devices. The first is the use of high bandwidth dual-stage actuator servo systems...

- Siemens' Process Safety Systems Deliver Modern Features on a Proven Platform
- Traditionally, safety protection refers to add-on components that protect personnel working in or near hazardous manufacturing processes from injury or death. Today, however, safety solutions go far beyond this notion. Today, manufacturers are looking for reduction in the cost of configuration, training, and support of their safety systems along with...

- Effects of Corner Frequency on Bandwidth and Resonance Amplitude in Designing PZT Thin-Film Actuators
- In the last decade, lead zirconate titanate oxide PZT thin-film actuators have received increasing attention because of their high frequency bandwidth, large actuation strength, fast response, and small size. The PZT film thickness is usually less than several microns as opposed to hundreds of microns for bulk PZT patches that...

- A Dual Actuator Logging Disk Architecture
- This paper presents a dual actuator logging disk architecture to minimize write access latencies. The paper reduces small synchronous write latency using the notion of logging writes, i.e. writing to free sectors near the current disk head location. However, the paper shows through simulations that logging writes by itself is...
