Patent EP-0266756-A3 (EP)
IPC: H04N7/16
Filed: 1987-11-04
Abstract: Scrambling and descrambling systems utilizing 
jamming signals provide improved pictures with minimal 
distortion due to ghosts and artifacts. The television 
signal is combined with a jamming signal or signals 
located preferably in the vestigial sideband (VSB) of 
the modulated picture carrier and at about a null in the 
spectrum of the modulation of the picture carrier by the 
horizontal sync. The jamming signal or signals also 
preferably are placed between the harmonic components of 
the horizontal sync which define the horizontal sync 
spectrum and at frequencies which comply with 
governmental regulations respecting frequency locations 
of strong signals for CATV purposes. The jamming 
signals are generated by phase locking to the horizontal 
sync signals of the television signals or to a 
submultiple of the horizontal sync frequency. Artifacts 
are further reduced by preemphasis of the transmitted 
television signal in the sideband opposite to that in 
which the jamming signal or signals are located and 
spaced by an equal frequency increment for the location 
of the jamming signal energy. In order to extract the 
jamming signal, so as to descramble the television 
signal for reproduction in the subscriber's television 
receiver, a network including at least one surface 
acoustic wave (SAW) resonator device is embedded in an 
all-pass network which allows essentially lossless 
transmission of the television signal spectrum, except 
 
 
for the jamming signal energy and enables that energy to 
be located close to (e.g., approximately 228 KHz) from) 
the picture carrier in the VSB for enhanced security.

Title: A contacless technique for semiconductor wafer testing
IPC: G01R15/16
Filed: 1988-07-22
Abstract: A contactless technique for semiconductor wafer testing 
comprising:  
depositing charges on the top surface of an insulator layer 
over the wafer to create an inverted surface with a depletion 
region and thereby a field-induced junction therebelow in the 
wafer, with an accumulated guard ring on the semiconductor 
surface therearound. The technique further includes the step 
of changing the depth to which the depletion region extends 
below the inverted semiconductor wafer surface to create a 
surface potential transient, and the step of measuring a 
parameter of the resultant surface potential transient.  
     This technique may be utilized to make time retention and epi 
doping concentration measurements.  
     It is especially advantageous for reducing the effects of 
surface leakage on these measurements.  
     In a preferred embodiment, corona discharges are used to effect 
the charge deposition configuration. Either corona discharge or 
photon injection are used to change the depletion region depth.

Title: Computer input device using an orientation sensor
IPC: G06F3/033
Filed: 1988-10-14
Abstract: A hand-held device (10) for controlling cursor movement on a 
data terminal (16) having a display (18). An internal 
orientation sensor (25) provides an electrical signal that is 
related to the orientation of the device without it being 
adjacent to any fixed surface. The orientation sensor includes 
a hollow spherical housing (38) having at least one LED (68, 70) 
and one phototransistor (72,74) mounted opposingly in the inner 
wall (74), along an axis (80) extending through the center point 
of the housing (38). The housing (38) is half-filled with a 
transparent liquid (76) having a specified viscosity and index 
of refraction and half-filled with air (78). A light beam 
emitted from the LED is refracted upon passing through the 
boundary between the air (78) and the liquid (76). As the 
orientation sensor rotates with respect to the vertical axis 
(76), the changing refraction angle of the light beam causes the 
phototransistor (72, 74) to detect changing intensities of 
light, which are representative of the angle of rotation.
