Filed: 1990-09-05
Abstract: A technique for encrypting and decrypting information signals normally arranged as a succession of lines of active information, with each line having a line timing reference, such as color video information signals. Active video portion is time shifted with respect to the horizontal sync portion of the corresponding line using a predetermined slowly varying time shifting function. The time shifting information is conveyed to the decryption site by encoding the instantaneous value of the time shifting wave form for the beginning of each field in the vertical blanking portion of that field. To provide a reasonable maximum time shifting range, portions of the trailing edge of the active video in the preceding line and portions of the leading edge of the active video in the current line are discarded. During decryption, the original line timing and color burst signals are discarded and new signals are generated which are time displaced from the active video portion by the original amount before encryption.

Inventor: JORGENSEN INER M
IPC: F01P7/04
Filed: 1990-09-28
Abstract: A  circumferentially  supported  fan  assembly  for drawing cooling  air  through  a  radiator  of  a  vehicle  is described.     The   fan   includes   a   fan   ring   extending circumferentially around the periphery of the fan, the blades of the fan extending from a central region to the fan ring. The  entire  weight  of  the  fan  is  borne  by  a  fan  support assembly which extends around the periphery of the fan ring, outside the path of air flowing through the fan.  The fan is the rotor of an electrically driven motor.  A rotor flange of the fan ring extends transverse to the axis of the rotation of the fan, providing a greater torque advantage for the motor. An electrical control circuit selectively controls the speed of the fan to maintain the liquid temperature of the radiator below a selected threshold value.   As additional cooling is required,  the  electronic controller  gradually  and  smoothly increases the power drawn from the engine to turn the fan to increase  its  speed  towards  a  selected  speed.    The  air permeability of the fan when  freewheeling  is  significantly increased because no central shaft or support structure blocks the airflow through the fan.

IPC: G03B7/16
Filed: 1990-10-26
Abstract: An exposure control system for a photographic camera employing a scanning type shutter that includes a pair of cooperating shutter blade elements automatically compensates for exposure altering variations in shutter blade element speed that may occur from one exposure interval to another. The exposure control system includes an encoder to provide information on the actual position of the shutter blade elements as a function of time during an exposure cycle. The encoder generates a series of pulses representative of relative blade element position as the blades are moved during the exposure cycle.      The time between these pulses is measured and directly converted into a signal representative of shutter blade element speed or velocity. This shutter blade speed signal is then employed to alter the duration of an exposure interval to compensate for any shutter blade element speed variations.
