Walter Jennings (chemist). Walter Goodrich Jennings (March 2, 1922 – July 5, 2012) was an American chemist, educator and entrepreneur. He was co-founder of J&W Scientific, which became the world's largest supplier of fused silica columns; the company was purchased by Agilent Technologies in 2000.

He was born in Sioux City, Iowa and grew up in Glendale, California. From 1940 to 1942, Jennings worked on a survey crew for the Union Pacific Railroad. He served with the United States Army in Europe during World War II. With the aid of the GI Bill, Jennings enrolled at the University of California at Davis with the aim of earning a degree in dairy science. He earned a Bachelor, Masters and PhD, eventually becoming a professor emeritus. His interest in flavor chemistry led him to investigate technologies such as gas chromatography to help investigate the chemistry behind the flavor. This led to technological innovations in support of gas chromatography including the production of fused silica (glass) capillary columns for separation of chemical compounds through this specialized analytical chemistry technique. Jennings and a graduate student began manufacturing capillary columns for gas chromatography; originally operating out of a garage, they went on to  form a manufacturing company J & W Scientific based in Folsom, CA.

Jennings produced over 200 publications in his field and was also in demand as a lecturer. He was awarded a Humboldt Fellowship in 1973, the Founders Award in Gas Chromatography from the Beckman Foundation, the M.J.E. Golay Award, the Keene P. Dimick Award, and the A.J.P. Martin Gold Medal from the Chromatographic Society. In 2004, he received the ANACHEM Award. He also received the Lifetime Achievement Award in 2008 from LCGC (Liquid Chromatography-Gas Chromatography). Jennings was chairman of the American Chemical Society Flavor Chemistry and Chromatography and Separation Science subdivisions.

Jennings died at home at the age of 90.

Eric E. Hagedorn. Eric E. Hagedorn (August 21, 1896June 22, 1963) was an American politician and electrical engineer who served one term as a member of the Wisconsin State Assembly.  A Republican, he represented the city and town of Wauwatosa, Wisconsin, and northwestern Milwaukee County.

Early life and education
Born in Milwaukee, Wisconsin, Hagedorn graduated from Milwaukee Lutheran High School in 1912. He attended the Milwaukee School of Engineering from 1913 to 1915, and took a correspondence course in law.

Career

He served in the United States Navy and was commander of the 8th battalion at Great Lakes Naval Station for two and a half years.  Outside the Navy, he worked as an electrical engineer, working as superintendent of the Jung Electric Company, a sales manager for the Electrical Equipment Company, and manager and secretary of the Airforce Corporation.

He was elected Town Council President for the Town of Wauwatosa, and, in 1940, chose to challenge incumbent Republican Assemblyman Walter Nortman in the Republican primary.  Hagedorn won a stunning upset in the primary, but the Milwaukee County Republican Party disavowed the results, stating that Hagedorn was not a "bona fide Republican."  The County Party endorsed Nortman, who ran in the general election as an Independent Republican.  Hagedorn won the general election anyway, taking 47% of the vote in a four-candidate race.  Hagedorn ran for re-election in 1942, but was defeated in the Republican primary by Milton F. Burmaster.

During his one term in the Assembly, Hagedorn served on the Assembly Committee on Education and the Committee on Commerce and Manufactures.

Personal life 
Hagedorn died of cancer on June 22, 1963, at Park Falls, Wisconsin, where he had lived for eight years prior to his death. He was interred at Two Lakes Cemetery in the city of Phillips, Wisconsin, in Price County.

Check pilot. A check pilot (or check airman) is an aircraft pilot who performs an oversight, safety, and qualification role for commercial pilots undergoing evaluation. The role of the check pilot is to ensure that the flight crew member has met competency standards before the check airman releases the crew member from training and to ensure that those standards are maintained while the crew member remains in line service.

A check pilot is authorized to conduct the following:
Pilot proficiency or competency checks conducted as a qualification curriculum segment in the operator's approved training program, from either pilot seat in an aircraft, whether in flight, or in a simulator, as appropriate.
Flight instruction in the operator's approved training program, from either pilot seat in an aircraft in flight, or in a simulator, or both, as appropriate.
Supervision of the reestablishment of landing ability.
Special checks conducted as a qualification curriculum segment of the operator's approved training program, provided the check airman is qualified in the specific activity for which the special check is being conducted (such as Category II (CAT II) and Category III (CAT III) operations).
Certification of the satisfactory proficiency and knowledge of airmen after completion of a flight training curriculum segment or flight training module.
When authorized by the operator, ground instruction for airmen, and certification of the satisfactory completion by an airman of a ground training curriculum segment.

OVMS. The OVMS (Open Vehicle Monitoring System) allows a user to connect to the CAN bus in a vehicle so that the user can view and monitor several parameters of vehicle operation, such as state of battery charge for an electric vehicle. The system includes hardware (a board that connects to the vehicle), a server, and mobile device software. Early work on this system was done by enthusiasts of the Tesla Roadster; the system is also being adapted for use with the Nissan LEAF, Chevrolet Volt / Opel Ampera, Renault Twizy, Think City, Tazzari Zero, Mitsubishi i-MiEV and Kyburz and has a Generic OBDII module. OVMS has similarities to Nissan's proprietary CarWings system.

Nanophotonic coherent imager. Nanophotonic coherent imagers (NCI) are image sensors that determine both the appearance and distance of an imaged scene at each pixel. It uses an array of LIDARs (scanning laser beams) to gather this information about size and distance, using an optical concept called coherence (wherein waves of the same frequency align perfectly).

NCIs can capture 3D images of objects with sufficient accuracy to permit the creation of high resolution replicas using 3D printing technology.

The detection of both intensity and relative delay enables applications such as high-resolution 3D reflective and transmissive imaging as well as index contrast imaging.

Prototype 

An NCI using a 4×4 pixel grid of 16 grating couplers operates based on a modified time-domain frequency modulated continuous wave (FMCW) ranging scheme, where concurrent time-domain measurements of both period and the zero-crossing time of each electrical output of the nanophotonic chip allows the NCI to overcome the resolution limits of frequency domain detection. Each pixel on the chip is an independent interferometer that detects the phase and frequency of the signal in addition to the intensity. Each LIDAR pixel spanned only a few hundred microns such that the area fit in area of 300 microns square.

The prototype achieved 15 μm depth resolution and 50 μm lateral resolution (limited by the pixel spacing) at up to 0.5-meter range. It was capable of detecting a 1% equivalent refractive index contrast at 1 mm thickness.
