EXPENDABLE LAUNCH VEHICLE VIDEO SYSTEM

Brierley, Scott, Lothringer, Roy 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Delta expendable launch vehicle has been flying onboard video cameras. The camera is an NTSC analog camera that directly modulates an FM transmitter. A standard FM deviation is used to maximize link performance while minimizing transmitted bandwidth. Pre-emphasis per CCIR recommendation 405 is used to improve the video signal-to-noise ratio. The camera and transmitter obtain power from either a separate battery or the vehicle power system. Lighting is provided by sunlight, or a light may be added when sunlight is unavailable. Multiple cameras are accommodated by either using multiple transmitters or by switching the individual cameras in flight. IRIG-B timing is used to correlate the video with other vehicle telemetry.

Synkroniserad insamling av videoström från flera analoga källor / Synchronized collection of video stream from multiple analog sources

Tägt, Daniel, Hansson, Jonny January 2013 (has links)
Arbetet bygger på att modernisera Saab AB:s kamerasystem med videoservrar. Systemet ska kunna samla in ett antal analoga videoströmmar och omvandla de till digitala. Kamerorna är utav bildformaten NTSC och PAL vilket innebär att de har olika bilduppdateringshastigheter. Det medför att en fördröjning kommer ske i PAL-strömmen. En programvara ska utvecklas för att ta in dessa strömmar, spara och synkronisera de.

Low-Variation 1 MHz Clock Generator,High Sensitivity Linear Voltage-to-Frequency Converter,and High-PSR Bias Circuit for NTSC SYNC Separation

Lee, Tzung-Je 13 July 2004 (has links)
This thesis includes three topics. The first topic is a low-variation 1 MHz clock generator. The second one is a high sensitivity linear voltage-to-frequency converter. The last one is a high-PSR bias circuit for NTSC SYNC separation. All of the circuits can be applied to related consumer electronic products. The low-variation 1 MHz clock generator includes a bias circuit which automatically compensates the drifting caused by temperature variations. Furthermore, the circuit contains neither BJTs nor diodes to reduce the area cost. The frequency variation is measured to be less than 2.55\% in the range of 0¢J~90¢J. The high sensitivity linear voltage-to-frequency converter is mainly constructed by a window comparator[11]. We analyze and improve the performance of accuracy to achieve both high accuracy and high sensitivity. The accuracy error is less than 1% and sensitivity is 84 KHz/V in the voltage range of 0.1V~0.8V. The high-PSR bias circuit for NTSC SYNC Separation is implemented by a bandgap reference which is controlled by a feedback loop to reduce the interference of the environment. The measurement variation of the bandgap reference is less than 1\% when the variation of power supply is 10\%. The sensitivity of the bandgap reference to temperature is measured to be 0.0006V/¢J.

Vlci v hořáku / Wolves in a Burner

Šprincl, Petr Unknown Date (has links)
My grandfather 's name is Adolf Šprincl . Over 12 years he was a professional coach hockey teams in France (with various interruptions from 1971 to 1994 ) , where he trained teams in Tours, Villard de Lans and Grenoble. The last named team is most associated with him. Les Loups de Brleurs - Wolves in the burner. My father's name is Milan Šprincl . From the age of 5 years he`s playing hockey. From the age of 18 years it played at a professional level in the Czech first league . The most important places in his life are hockey stadiums in Jihlava and Hodonin. Both stadiums stands on the site of a old cemetery in neighborhood there is a Baroque cemeterychapel. I tried to play hockey, but I failed. I continue in the family tradition of hockey and also the grandfather's work in Grenoble. Documentary film with elements of experimental manipulations and fiction passages will map to the development of French hockey and also the mystique associated with hockey . Attempts to reveal a seemingly random connections between hockey and sacred land for the rest of the dead. At the same time this film plans to close a series of films with the theme of my personal family history, to which I perceive in abstract forms. The film is shot on VHS camcoder. I shoot hockey stadiums (especially in Hodonin and Jihlava ) in which interests me as architectural monumentality of these sports , but also the context in which they are found (hockey arena on former cemeteries , etc. ) . The next part takes place in France , near Grenoble, where he focuses on the current state of French hockey (interviews with prominent personalities of French hockey - Jean Leblond / Vice President of the French hockey , Dany Grandor / former player Grenobelu - officer team, Stéphane Bailles / first hockey scout in France, Jean - Luc Dalaison / journalist Le Dauphiné and others) and link to my grandfather , who is one of the most important figures in the history of the hockey team Bruleurs Les Loups de Grenoble . Another important part is i work with historical documents ( articles in French and Czech press about his grandfather , his personal correspondence , notebooks with notes for training and game strategy , and also relics of his time in France) and a part takes place on the ice rink , where you will be using the other game lines and projections manipulated match in hockey (tells the legend of the mountain Vercors of wolves who ate people ) . Part of the film is the creation of costumes (especially hockey jerseys ) and props.
