Title: Method and apparatus for spectroscopic measurement of the concentration of a gas
Inventor: TELL ROBERT
IPC: G01J3/433
Filed: 1990-01-05
Abstract: Abstract Method and apparatus for spectroscopic measurement of the concentration of a gas in a sample where you detect the intensity of light from a light source (1) passed through the sample (4) and through a reference cell (5) and gene-rates a signal which represents the concentration of the gas. A laser diode (1) constitutes the light source which is locked to the absorption line of the gas at known con-centration and pressure contained in a reference cell (5) The laser light with the properly selected wavelength is distributed via optical fibers (2,3,6) and/or glass prisms (19,20)  to the reference cell  (5)  and the sample  (4). Nongasrelated transmission variations in the measurement path or in the optics is automatically compensated for by a special laser modulation which generates a time multiplexed reference. The measurement can be performed in a measurement cell  incorporating  several  reflective  mirrors  (30)  to reflect the laser beam several times inside the measurement cell thereby increasing the effective length of the measure-ment path. The measurement can also be performed using an optical fiber designed so that the surrounding gas or fluid via the evanescent field effects the laser light so that the concentration of the substance in question in the surround-ing fluid or gas can be determined.

Patent CA-2034084-A1 (CA)
Inventor: WHITE LISA K
IPC: B64G1/34
Filed: 1991-01-11
Abstract: A method for East/West stationkeeping of a geostationary satellite maintains the osculating value of longitude from exceeding a specified deadband for a specified drift period between maneuvers. In the planning, the mean longitude, the mean drift rate and the mean eccentricity vector are calculated and then maneuvers are executed to maintain the values below a magnitude such that the osculating longitude will be within the specified deadband over a specified draft period. The target conditions are achieved through a plurality of maneuvers which initiate a period of free drift which lasts for a specified number of days. During the free-drift period, longitude remains within its deadband, and no additional maneuvers are needed or are performed. The method has the advantage that it can take into account limitations on thruster on-time by allowing far a generalized number of stationkeeping maneuvers.

Title: Aircraft radar altimeter with multiple target tracking capability
Inventor: HAGAR JAMES R
IPC: G01S13/935
Filed: 1991-08-27
Abstract: An aircraft radar altimeter includes a programmed microcontroller which permits effective simultaneous tracking of at least two targets such that, for example, both ground and obstacles on the ground can be simultaneously tracked, thus avoiding crashes when the aircraft is operating at very low altitudes. The microcontroller is operatively coupled to the radar transmitter and to the receiver so that information relating to a first target can be stored away while a search and track operation is run on a second target. The information concerning a detected second target is likewise stored away and the microcontroller permits alternate tracking of the two targets with the stored information being used as the basis for establishing an initial position for a target when tracking of that target is resumed.
