VersaLogic Launches 'Osprey' - Small Powerful Embedded Computer Based on Intel Bay Trail Processor

Press Release


Tualatin, OR – June 28, 2016 
 

VersaLogic Corp., the embedded industry's most trusted computer company, has announced Osprey - an extremely small, rugged, embedded computer. 


This next generation of the VersaLogic Embedded Processing Unit (EPU) format combines processor, memory, video, and system I/O into an extremely compact full function embedded computer. The computer has a footprint just slightly larger than a credit card.

The Osprey was engineered to meet the military, avionic, and medical industries' evolving requirements for smaller, lighter, and more powerful embedded systems. Roughly the size of a credit card and less than 1.1 inches (28mm) thick, the Osprey is a highly-integrated embedded computer. It combines the new 4th generation Intel® Atom™ "Bay Trail" processor, with newer system interfaces, in a form factor designed to withstand extreme temperature, impact, and vibration.

Osprey is available in single, dual, and quad core models. The single core is suitable for lower-cost, lower power systems, while the quad core is ideal for UAV video applications where both higher performance and small size are important.

"We are excited to offer another EPU model with increased I/O capabilities. Adding USB 3.0, an additional half-sized mini PCIe socket, a second Ethernet port, digital I/O, and an I2C port allow our customers to support their I/O needs in one small package," said Gary Harris, VersaLogic's Director of Technology.

The Osprey features an industrial temperature Intel Atom E38xx processor optimized for performance and power balance. Osprey provides compatibility with a broad range of x86 operating systems and application development tools for reduced cost and development time.

Powerful Video Processing

Intel's advanced Gen 7 HD graphics engine provides outstanding graphics performance and is capable of supporting two simultaneous 1080p video streams. On-board hardware acceleration is available for encode/decode of H.264, MVC, VP8, VC1/WMV9, and other standards. The graphics engine also supports DirectX 11, Open GL 4.0, full HD video playback, dual display support, and resolution up to 2560 x 1600 @ 60Hz. Osprey supports a Mini DisplayPort++ output as well as a single-channel LVDS display output.

High Performance I/O Capabilities

Osprey's I/O connectivity includes dual Gigabit Ethernet ports with network boot capability, one USB 3.0 and four USB 2.0 ports, I2C, eight digital I/O's, and two serial ports. A SATA 3 Gbits/s interface supports high-capacity rotating or solid-state drives. Full and half-sized Mini PCIe sockets, a microSD socket, and on-board eMMC (on some models) provide flexible solid-state drive (SSD) options. Systems can be enhanced by leveraging the Mini PCIe sockets with plug-in Wi-Fi modems, GPS receivers, MIL-STD-1553, Ethernet, Firewire, and other mini PCIe cards/modules.

Designed, Manufactured and Tested for Extreme Environments

Designed and tested for industrial temperature (-40° to +85°C) operation, the Osprey also meets MIL-STD-202G specs for impact and vibration.
Osprey's on-board power filtering adds an important layer of protection for glitches caused by dirty or unstable power sources. The wide input voltage range (8 to 17 volts) greatly simplifies system power supply requirements. It is fully compatible with automotive type (nominal 12V) power systems. Soldered-on RAM and fanless thermal solutions provide additional ruggedisation for use in harsh environments.

Long-term Availability

The Osprey is covered by VersaLogic's 5-year product warranty and 5+ year availability guarantee. VersaLogic's Life Extension programs typically keep products available for 10+ years. Customisation services to help customers create unique solutions are available for the Osprey, even in low OEM quantities. Customisation options include conformal coating, revision locks, custom labeling, customized testing and screening, and more.

Pricing and Availability

The Osprey (part number VL-EPU-3311) is now in stock. OEM quantity pricing starts at $709 for the single-core model with 2 GB RAM.

Automotive NVH Data Logging for Todays Vehicles

Author - Laura


The Ford Model A was the original car produced by Ford, and was first sold to Ernst Pfennig, a Chicago dentist on July 23, 1903. Only 1,750 Model As were made from 1903 through 1904, until it was replaced by the Ford Model C during 1904.

Ford Model A
The car came as a two-seater runabout or four-seater tonneau model with an option to add a top. The horizontal-mounted flat-2, situated amidships of the car, produced 8 hp (6 kW). A planetary transmission was fitted with two forward speeds and reverse, a Ford signature later seen on the Ford Model T. The car weighed 1,240 lb (562 kg) and could reach a top speed of 28 mph (45 km/h). It had a 72 inch (1.8 m) wheelbase and sold for a base price of US$750. Band brakes were used on the rear wheels.

Although Ford advertised the Model A as the "most reliable machine in the world", it suffered from many problems common to vehicles of the era, including overheating and slipping transmission bands. 



Cars today go through stringent tests in the development stage, before they even reach the market. 
United Electronic Industries (UEI)’s popular UEILogger Cube in conjunction with the DNA-AI-211 ICP/IEPE interface and the DNA-AI-208 or AI-224 strain gage interfaces have been used by a wide variety of customers in the study of vehicle NVH (Noise, Vibration and Harshness) characteristics.

The Cube is an ideal measurement platform for in-vehicle automobile NVH testing, being compact, rugged and running off any power supply between 9 and 36 VDC. This combination makes it easy to fit the cube in the boot, engine bay or underneath a seat. As well as logging the NVH data, the UEILogger can also acquire CAN data, allowing simply correlation between the vehicle dynamics (e.g., speed, RPM) and NVH.

All this is possible without writing any code as the UEILogger is programmed by a simple, intuitive Windows GUI.

Vehicle NVH Testing - Automotive April from Sarsen Technology!

Noise, vibration and harshness (NVH), also known as noise and vibration (NV) is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks.

There are many sources of noise in a vehicle, including the engine, driveline, tyre contact patch and road surface, brakes, and wind. Noise from cooling fans, or the HVAC, alternator, and other engine accessories is also fairly common.

There are three principal means of improving NVH:
  1. Reducing the source strength, as in making a noise source quieter with a muffler, or improving the balance of a rotating mechanism 
  2. Interrupting the noise or vibration path, with barriers (for noise) or isolators (for vibration) 
  3. Absorption of the noise or vibration energy, as for example with foam noise absorbers, or tuned vibration dampers.
Specific methods for improving NVH include the use of tuned mass dampers, sub-frames, balancing, modifying the stiffness or mass of structures, retuning exhausts and intakes, modifying the characteristics of elastomeric isolators, adding sound deadening or absorbing materials, or using active noise control. In some circumstances, substantial changes in vehicle architecture may be the only way to cure some problems cost effectively.

The UEI Cube is an ideal measurement platform for in-vehicle automobile NVH testing. The Cube is small, rugged and runs off any power supply between 9 and 36 VDC. This combination makes it easy to “bury” the cube in the car’s trunk, engine compartment or under a seat.

UEI’s popular UEILogger Cube in conjunction with the DNA-AI-211 ICP/IEPE interface and the DNA-AI-208 or AI-224 strain gage interfaces have been used by a wide variety of customers in the study of vehicle NVH (Noise, Vibration and Harshness) characteristics.


In addition to logging the NVH data, the UEILogger can also acquire CAN data, allowing simply correlation between the vehicle dynamics (e.g. speed, RPM) and NVH. All this is possible without righting any code as the UEILogger is programmed by a simple, intuitive Windows GUI.
