| 144 | Passive Electro-Optical Tracker | US12709780 | 2010-02-22 | US20100278387A1 | 2010-11-04 | Ilya Agurok; Waqidi Falicoff; Roberto Alvarez |
| A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a speed estimate from their temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Three methods are given to determine the azimuth and range of a projectile, one for clear atmospheric conditions and two for nonhomogeneous atmospheric conditions. The first approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. The second calculates this angle using a different algorithm. The third uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate. | ||||||

| 154 | Optical tuft for flow separation detection | US09369472 | 1999-08-06 | US06380535B1 | 2002-04-30 | Todd G. Wetzel; Sandra F. Feldman |
| Disclosed are flow separation detectors and, more particularly feedback sensor arrangements adapted to provide for the measurement of surface aerodynamic flow phenomena, and especially with regard to aerodynamic flow separation which is encountered over a surface. In order to obviate or ameliorate the electrical energy requirements in the provision of feedback sensor arrangements, particularly such which are employed for a closed-loop control of aerodynamic flow separation; for instance, that on the wing of an aircraft wherein there can be encountered a breakdown of a boundary-layer flow which may adversely affect the performance of the aircraft, provided is a novel system of flow separation sensors which are based on fiber optics and which may be employed for separation feedback control. In particular, the sensors which are based on fiber optics may employ an optical tuft arrangement based on the thermal/fluidic principles of the electrical thermal tuft, but with the employing of fiber optics signal and energy transmission instead of electronics. To that effect, the light transmitted through the fiber optics is adapted to be converted into heat enabling a packet of heated fluid to be convected in the direction of a predominant aerodynamic flow, and to impact or contact one of the temperature sensors which are based on fiber optics at a small following time interval, so as to provide the required information concerning aerodynamic flow separation. | ||||||

| 158 | Cardiac blood flow sensor and method | US331416 | 1994-10-31 | US5520190A | 1996-05-28 | George J. Benedict; Timothy A. Fayram |
| A cardiac blood flow sensor includes a light source and a photodetector within a housing. The light source projects a beam through a fiber optic line having a first end optically connected to the housing and a distal tip positioned within the patient's heart. A ruby positioned at the distal tip is heated by the beam, and fluoresces for a period of time after illumination ceases. The period of time depends on the temperature of the ruby, so that the fluorescent light is transmitted back through the optic line to the photodetector. The signal generated by the photodetector may be analyzed to estimate the blood flow rate, due to the thermal effect of blood flowing past the heated ruby. The flow sensor may be contained in a common housing with a defibrillator that is implanted in a patient. The sensor may remain inactive until a tachycardia or rapid heart rate is detected, upon which the light source is activated. The cardiac condition is analyzed based on the detected heart rate and blood flow and, if needed, an appropriate therapy is delivered. | ||||||

Further, an improved temperature sensitive matching resistor is suitably used in the mass flow sensor, in which a plurality of temperature sensitive resistances having equal characteristics are integrated. | ||||||
