Title: Method and apparatus for direction related interpolation
Inventor: BOIE WERNER
IPC: H04N5/44
Filed: 1993-03-01
Granted: 2001-08-21
Abstract: For Proscan conversion adjacent fields cannot be used to inter-polate moving objects because motion blur will be introduced then. The most simple solution is to insert the average of the two adjacent lines for each missing line. A technique superior to vertical averaging represents the DIAG3 algorithm, where ac-cording to the found minimum gradient the orientation of the in-terpolation filter is chosen. But in case of high diagonal frequencies interpolation errors will occur.      Therefore it is tested if the reconstructed pixel value exceeds or falls below the pixel values in the two adjacent lines of the input signal. If this happens, instead of one of the detected diagonal directions the vertical direction is taken, i.e. a ver-tical averaging is carried out.

Title: Atmospheric gas separation method
Inventor: KRISHNAMURTHY RAMACHANDRAN
IPC: F25J3/02
Filed: 1995-01-19
Granted: 1997-10-14
Abstract: A method of cryogenically separating a mixture of atmospheric gases within a distillation column system having at least one distillation column.  In accordance with the method, liquid and gaseous phases of the mixture of atmospheric gases to be separated are countercurrently passed through structured packing..  The column is operated with a pressure greater than 2 bars and with a vapor rate of the vapor phase that is less than a critical vapor rate at which the column floods and which varies with the liquid rate of the liquid phase. Minimum and critical vapor rates at which the column floods are set in accordance with experimentally derived data for maximum column utilization in terms of packing volume or column throughput.  Additionally, separation performance in terms of HETP increases with the increase in pressure so that a lower than prior art height of structured packing can be used to obtain a particular separation.

Title: Flexible potentiometer in a horn control system
Inventor: LANGFORD GORDON B
IPC: B60R21/2165
Filed: 1994-05-10
Granted: 1999-03-16
Abstract: A flexible potentiometer acts as a horn actuator in an automobile horn control system. In a preferred embodiment, the flexible potentiometer is adhered to a flexible substrate, which is in turn adhered to the inside surface of an air bag hub cover. The shape of the flexible potentiometer is chosen so that the automobile horn will sound when the driver presses against particular potions of the outside of the hub cover. The resistance of the flexible potentiometer changes as its shape changes as the user presses against the hub cover. A horn control circuit responds to extremely rapid changes in the resistance of the flexible potentiometer, but not to more gradual changes caused by, for example, temperature changes. Additional flexible potentiometers may be used to control other functions such as cruise control.
