Title: Potentiostated, three-electrode, solid  polymer electrolyte (spe) gas sensor having  highly invariant background current characteristics  with temperature during zero-air operation
Inventor: LACONTI ANTHONY B
IPC: G01N27/70
Filed: 1978-07-27
Granted: 1981-12-08
Abstract: ABSTRACT OF THE DISCLOSURE     A compact electrochemical gas sensing cell is described for detecting gases such as carbon monoxide, N02, alcohol vapors, etc. The cell is characterized by temperature stability during zero-air operation so that background current with no gas flow is eliminated or minimized. This cell utilizes a hydrated solid polymer electrolyte having reference, sensing and counter electrodes mounted on the surface thereof with one side of the membrane being flooded with distilled  water to provide self-humidifcation of the cell by water vapor transport across the membrane.  A po?entiostatic circuit is utilized to control the potenital on the sensing circuit and also to maintain a fixed potential difference between the reference and the sensing electrodes. In addition, the chemical, electrochemical, and thermal characteristics of the sensing and reference electrodes are matched so that the sensor is highly temperature invariant during zero-air oper-ation, by making the feference and sensing electrodes similar in s?cture, locating them closely together preferably on the same side of the membrane but outside of the current flux lines between sensing and counter electrodes. As a result, a small compact gas sensing device is made possible  which does not require temperature compensation for zero gas operation.

Title: Digital video effects system employing  a chroma-key tracking technique
Inventor: INABA MASAO
IPC: H04N9/75

Abstract: ABSTRACT OF THE DISCLOSURE         In a chroma-kev tracking system for compressing and inserting a second television picture into an area corresponding to a chroma-key frame located at a specified position in a first television picture, there is described a tracking system which compresses the second picture to have an aspect ratio correspond-ing to that of the chroma-key frame into which it is to be in-serted.  In known systems, the aspect ratio of the inserted picture is not varied to that of the chroma-key frame with the result of awkward-looking pictures from some camera angles.  In this invention, a key signal is produced representing the key frame and which is used for producing a position signal represent-ing the position of a circumscribed key frame.  From the position signal there is produced an imaginary frame position signal representing an imaginary-frame with the same aspect ratio as the first and second pictures.  A compressed second video signal representing the compressed second picture is produced from the second video signal and imaginary-frame position signal to be identical in size with the imaginary frame.  The first video signal and compressed second video signal are selectively gated in response to the key signal such that the compressed second picture is inserted into the chroma-key frame of the first pic-ture.

Abstract: ABSTRACT OF THE DISCLOSURE    The plastic non-conducting housing is provided with two pairs of terminals the inner ends of which serve as busses and fit in grooves in the interior, each pair being separated by an integral rib which is slightly higher than the busses so the associated spring loaded roller-like shorting bar mounted in the axially moveable carrier is held out of contact with the busses.  The molded housing is cored along the length of the rib where switching is desired.  There-fore, where the housing is cored there is no rib to prevent the shorting bar from completing the circuit between the busses.  When the shorting bar engages the busses the friction between the loading spring and the knurled central section of the roller is greater than the friction between the roller and the busses so the roller slides on the busses to obtain "wipe".  When the roller engages the rib the friction between the roller and rib is greater than between the roller and spring so the roller rolls and will present a new surface to the busses on the next operation.  The carrier is spring loaded to project out of the housing and is moved inwardly in response to the position of an external mechanism.
