Title: Security hinge utilizing concealed radiative sensing to detect hinge position
Inventor: BUBLEWICZ LESZEK
IPC: E05D11/00
Filed: 1988-12-21
Granted: 1992-11-10
Abstract: ABSTRACT      A hinge construction for monitoring and detection of unauthorized opening of a door.  The apparatus comprises a radiative emitter and detector concealed within the body of the hinge knuckles so as to be in communication with each other when the hinge leaves, and therefore the door, are in a closed position.  This communication is permitted through an opening in a notched collar which is juxtaposed between the emitter and detector elements, the notch being aligned with the emitter and detector when the hinge is closed.   The opening of the hinge leaves rotates the collar to misalign the collar notch with the emitter and detector elements, thereby causing an electronics circuit module to form a change of state signal which may then be reported to  an external monitoring or alarm system.          Closing the hinge leaves to realign the notch with the emitter and detector elements will result in the sensing means being reset.

Title: Frequency selective video signal intraframe processor
Inventor: SMITH TERRENCE R
IPC: H04N11/24
Filed: 1989-05-18
Granted: 1992-05-19
Abstract: RCA 85,143 Abstract A widescreen television signal containing center panel information and time compressed side panel information in an overscan region is intraframe processed above a given frequency only with respect to the center panel information.  The intraframe processing apparatus includes a signal delay network with first and second 262H delay elements coupled between an input and an output of the delay network.  During a first field interval, signals from the delay input and from an intermediate point between the delay elements are subtractively combined to produce a difference term which is coupled to a signal path.  During a second field interval, signals from the delay output and from the intermediate point are subtractively combined to produce a difference term which is coupled to the signal path.  An intraframe processed output signal is produced by combining the difference terms from the signal path with a signal from the intermediate delay point.  A filter and an electronic gate in the signal path determine frequency selective intraframe processing of the center panel information alone.
