Abstract: ABSTRACT OF THE DISCLOSURE        A system for reducing noise in a color video signal includes a delay or storage device for storing a single television frame, and means for combining the signal stored in the storage device with the arriving video signal for producing an output video signal containing a fractional amplitude portion of the stored signal and a fractional amplitude portion of the arriving signal, the system being operative automatically to change the fractional amplitude portions of the two signals in complementary fashion as a function of the difference between stored and arriving video signals, which difference, signifying motion, is ascertained by pixel-by-pixel comparison of the stored and arriving video signals.  To prevent the system from incorrectly interpreting certain types of noise as motion, the chrominance component is removed from the stored and arriving video signals before they are compared.

Abstract: Abstract of the Disclosure A deicing and traction forming composition in which particles of clay are impregnated and coated with a salt, such as sodium chloride, calcium chloride, and/or ammonium chloride so that, when the particulate material is used to deice and form a traction surface, the salt immediately begins the ice melting action followed by a more gradual action form the release of the salt from the particles.  The particles are readily disintegratable under the pressure of foot and vehicle traffic to re-lease the absorbed salt and to form a traction surface on the ice.  A method is used in the production of the composition consisting of heating crushed clay to drive off the moisture and, after screening the particulate material to obtain a somewhat uniform particle size and while it is still at an elevated temperature, spraying the particles with a salt solution.  The salt solution is absorbed and adsorbed by the particles, and the moisture is quickly driven off by the heat from the particles, thus leaving a dried particulated mass which can easily be stored, packaged, shipped and used in particulate form.     1,

Abstract: Abstract of the Disclosure In a speech recognition system responsive to oral inputs or speech signals as input means for various machines including computers, there is described a recognition system in which the rejection standard, against which all speech recognition results are compared for accuracy, is variable accord-ing to the level of background noise, avoiding the problems of preset, fixed standards found in known systems.  Ambient noise levels are measured for intensity, and this measurement is used to control the rejection standard. A rejection unit, responsive to the rejection standard, rejects those input speech signals, recognized as such by a recognition unit, which do not exceed the threshold level of accuracy as determined by the rejection standard.

Title: Controlled current inverter and motor control system
Inventor: ESPELAGE PAUL M
IPC: H02P3/18
Filed: 1979-07-13
Granted: 1983-04-26
Abstract: ABSTRACT OF THE DISCLOSURE           A controlled current inverter system forms the basis of an a.c. motor drive system for furnishing the motor load with a variable frequency, variable magnitude a.c. current from an inverter which is supplied from a variable d.c. current source by way of a d.c. link including an inductor.  Torque is the control parameter employed in the system and the motor speed and torque are controlled through the control of motor flux and motor current, by maintaining a controlled ratio between the direct and quadrature motor currents, through separate control paths to the d.c. source and the inverter.  A third control path functioning on the difference between the desired and actual motor flux serves as a modifier to the main control paths to improve overall operation and control.  Means associated with the basic control paths provide for dynamic braking of the motor.
