FlyOver Visual Map Technology the First 3D Aerial Imagery Map to Enrich Kenwood's New Car Navigation System

By Anonymous

SEVILLE, Spain--(BUSINESS WIRE)--Oct. 14, 2002--FlyOver Technologies, Inc. announced today that the company's Visual Map(TM) technology was implemented in Kenwood's latest release of a Hard Disk Drive-based Car Navigation System in Japan, enriching users with Aerial map "Sky Cruise View".

It is the first car navigation system where aerial imagery is implemented as a realistic 3D navigation map with all map attributes. Using the database of aerial imagery, "Sky Cruise View" can indicate the current car position and trace the car movement in real-time via an on board GPS. In addition the "Sky Cruise View" provides route guidance and Point of Interest placement. "Sky Cruise View" can be displayed on split screens, can change map scales and angle of view continuously, and can scroll or turn around freely. The same familiar digital maps user interface, feel and use are implemented in the new "Sky Cruise View". "Sky Cruise View" supports 13 major Japanese cities.

Isaac Levanon, Chairman and Chief Executive Officer of FlyOver, stated, "Kenwood's latest car navigation system is a vote of confidence in the commercializing value of FlyOver technology to enhance drivers' navigation experience. We overcame major technical barriers to provide smooth continues movements over the 3D image. It enables FlyOver to offer car navigation providers the benefit to integrate FlyOver technology without redesigning their hardware, hence reducing both cost and time to market."

MEMS motion tracker features gyroscopes and full navigation engine

By Anonymous

August 11, 2004 -- The IMT6000, manufactured by www.imego.com of Sweden, is the first ultra light INS device able to track motion for 10 seconds with positional accuracy, in x,y,z coordinates, of a few centimeters and angular accuracy surpassing 0.3 degrees. The IMT6000 can track velocity during 20 seconds of motion to within 0.01 m/s.

The system consists of a 60 gram IMU sensor head that collects, digitizes, stores and transmits all sensory data. A stand-by laptop receives the digital information via a BlueTooth link and computes all requested motion parameters, including positions and angles for all degrees of freedom. The complete motion event is captured and can be replayed in minute detail, with resolutions of several hundred samples per second.

The digital IMU sensor head builds on commercial micro machined gyros and accelerometers that are boosted with noise removal algorithms to reach noise levels of 0.005 deg/s/rootHz and 60ug/rootHz, throughout the generous measuring ranges of 3600 deg/s and 50 g. Another important parameter for motion tracking is the bias stability of the sensors. The IMT6000 is capable of stabilities down to 10 deg/hr and 100 ug. All sensors are sampled at 2.7 kHz and filtered in several stages to finally display information with 200Hz resolution.

www.imego.com
Imego is an independent contract research organization engaged in sensor system development as well as prototype production for industry. The company is specialized in micro-sensor systems within the fields of MEMS, biotechnology, magnetism and photonics.

Imego developed the IMT6000 and can customize this INS platform to a particular application as per customer’s specifications. Imego also develops and customizes sensor elements, sensor systems, and their packaging to satisfy further product requirements.

Applications
Imego’s motion trackers are currently primarily tuned to sports applications, focusing on explosive events that take on the order of a few seconds to complete. The IMT6000 measures, computes and displays all six motion parameters for all motion directions and all discrete time steps. The x,y,z accelerations, velocities, positions, angular accelerations, angular velocities, and angles then completely describe the motion and give the most accurate scientific description of the event that can be had.

Imego’s specialty is to take advantage of the general knowledge about a particular motion and customizing the device to limit the small errors inherent in fine grained motion tracking. For example, knowing that a race car always turns left on a track, we can tune the gyro scale factors accordingly, dramatically enhancing performance of the tracking. If the NASCAR circuit decided to switch directions one day, then that particular Imego motion tracker would have to be recalibrated. Another example is the understanding that almost all tennis players hold their racket nearly horizontal just before starting the serve motion. This kind of information can be exploited to determine specific sensor- and navigation parameters, which in the end improves navigation precision. Imego also uses advanced sensory calibration in a temperature controlled precision rate table, making it possible to compensate for non-linear behavior and temperature dependencies always present in MEMS sensors. The overall result is improved accuracy of all motion parameters, eclipsing tracking predictions based purely on manufacturer’s sensor specifications.

Beyond the world of sports, applications range from black boxes for industrial robots, precision positioning of film cameras, and accurate location of drill heads to computer animation and biomechanics. Basically, the IMT6000 can be applied whenever the problem entails measuring any motion parameter, while it at the same time is essential to use a sensor head that is small and light enough not to disturb the actual motion.

One prime example is Imego’s development of a light but accurate position measuring instrument, the GPS Shadow Explorer (GSE). Geodesic applications require a small and light instrument that quickly measures out a few unknown locations when not enough satellites are visible in the sky to use GPS. The GSE can then simply pinpoint the x,y,z coordinates, with the precision of a few centimeters, as long as each point can be reached within 25 seconds of walking from the known GPS coordinate.

Further Research and Development
In a research project, partly financed by SAAB Bofors Dynamics and SensoNor, Imego has developed a novel electronics platform, including a fully digital gyro ASIC, which boosts SensoNor’s low cost automotive gyroscope to good tactical grade performance. The combination of new ASIC and commercial gyro succeeded in resolving the rotation of the Earth, about 15?/hr, in late Q2 2004. This achievement further confirms Imego’s position as one of the world’s leading MEMS gyro research and prototyping companies. Less than a handful of research groups have previously been able to demonstrate this performance for silicon MEMS gyros before, and none for a low cost automotive gyro in commercial production.

Interad Introduces Modular HF Receiver System The Model 3100 sets new performance standards with: Phase Coherence No Local Oscillators High Dynamic Range 400 Mbps Firewire Output Connection

By Anonymous

Melfa, VA September 22 2003--

Benefits
By offering user-configurable features such as frequency coverage and antenna connections, Model 3100 addresses diverse needs and can meet the application requirements of a vast majority of Interad’s customers. The absence of local oscillators enables Model 3100 to achieve a minimum guaranteed dynamic range of 80 dB, with 90 db being most typical. These specifications are unheard of in the HF receiver market.

More Features
The system includes up to eight Digital Firewire modules. This module includes dual A/D converters and four IEEE-1394a Firewire transceivers for direct connection to Pentium PC, SUN, or other workstations for further signal processing and analysis.

The system also includes low-noise amplifiers with programmable gain to accommodate different antenna signal levels. It also includes digital downconverters to facilitate receiver
tuning to the desired frequency and recovery of the information signals. These baseband signals are available as I and Q complex data through the Firewire connections.

The Interad 3100 System clearly sets new performance standards in HF receivers and it does so at very competitive prices. This turnkey system is ready to be connected to antennas and workstations. It thus offers an integrated end-to-end approach to surveillance and monitoring of RF communications in the HF range. The system can interface with any standard workstation with a Firewire connection to perform analysis functions such as detection, spectrum analysis, or direction finding.

The Model 3100 is immediately available with U.S. delivery of 12–16 weeks ARO.
