A body and a head of the adaptor include seats for receiving the seal core with the passageway oriented for delivering the tube through the adaptor by way of an opening in the head. The seal core is adjustably compressed by the seats to form an adjustable seal around the tube. The openings in the head and body of the adaptor for the tube are larger in diameter than the back of the tube, and can be removed completely from the tube over the back end of the tube.

Abstract: A sensor includes two thermal energy detectors thermally insulated from one another. The first detector is warmed or cooled by radiation between it and the object being measured. The second detector is warmed or cooled by exchange of thermal energy with a thermal reference source until the second detector reaches a temperature that is a predetermined ratio with that of the first detector. A control circuit which receives signals from the detectors that represent their temperatures, provides control for the thermal reference. A third detector measures the temperature of the thermal reference source and provides a signal representative of the temperature of the reference source. A processor receives the signal from the third detector and provides a signal indicative of the temperature of the object.

Abstract: A first heater is attached to a sensor capable of emitting thermal radiation toward an object to be sensed. Electrical energy provided to the heater, required to maintain the sensor at a predetermined temperature when it is radiating energy toward the object is monitored by a circuit which provides a signal that is indicative of the required energy. A second heater provides a baseline temperature for the sensor. For greater accuracy, two sensors are heated by a common baseline heater. One of the sensors is shielded from radiation toward the object and controls the baseline heater, the other sensor emits thermal radiation toward the object and has a heater for maintaining it at a predetermined temperature for providing the signal indicative of the required energy as described above.

Abstract: A sensor electrode is capacitively coupled to the environment. Electric charges carried by surrounding objects induce corresponding electric charges on the sensor electrode. A high input impedance circuit senses change in charge on the electrode and provides a first varying signal indicative of that change. A second circuit compares the first signal against a threshold level and provides a second signal indicative of the movement. A pair of sensors may be included to cancel out extraneous environmental chasrges. Difference between charges on each sensor electrode of the pair is compared in a circuit which provides signal indicative of the difference. The varying signal is compared against a threshold to provide a signal indicative of the movement.

Abstract: A miniature active infrared motion detector contains a self-heating temperature sensitive resistor, an electronic circuit to maintain temperature of that resistor at predetermined constant level which is higher than ambient temperature. The detector actively radiates thermal energy to environment and measures electric power required to generate that energy. This provides information about temperature variations in surrounding objects. The detector is also comprised of a focusing system, image distortion means and a threshold circuit. An optical system can be made of a curved Fresnel lens or curved mirror, such as parabolic, cylindrical, spherical, etc. which distributes thermal radiation over narrow or wide field of view, potentially up to 360.degree.. The method of detecting movements is based on the use of a warm sensor whose temperature is maintained constant and above ambient.
