Title: Video identification card system
IPC: H04N11/04
Filed: 1988-12-16
Abstract: A video identification system for producing 
photo print identification cards having subject 
portrait, subject signature and subject related data in 
respective areas of the card as well as a data record 
including individual-specific data, an image of the 
subject, and an image of the signature of the subject. 
A personal computer controls the system to produce the 
identification card and the data record. The system 
includes a frame grabber which grabs a frame by only 
storing the 768 active video samples of each line of an 
NTSC signal for two consecutive fields. System 
operation may not be initiated without first having a 
supervisor unlock the personal computer and input a 
particular password. Further, each additional system 
operator must input their particular identification 
number into the personal computer whereby system 
security is maintained.

Title: Circuit for internal current limiting in a fast high side power switch
IPC: G05F3/24
Filed: 1990-06-14
Abstract: A current limiting circuit (200, 300, 400) for 
instantaneously limiting the peak current of a fast 
high side power switch (212) or power FET has a 
reference switch (213) or FET, a first comparator 
(218), a current source I CL , control circuitry (209), 
and a clamping circuit (238). The reference FET (213) 
is smaller than the power FET (212). The first 
comparator compares the voltage drop across the power 
FET (212) and compares it with the voltage drop across 
the reference FET (213) and produces a signal COMPOUT 
which initiates the turn-off of the power FET (212) if 
the voltage drop across the power FET (212), caused by 
a load current flowing through it, is greater than or 
equal to the reference FET voltage drop induced by I CL . 
The clamp circuit (238), having diodes (D₁, D₂) and a 
tracking current source I' CL , disconnects the FETS 
(212, 213) from the comparator (218) when they are OFF. 
The circuit (200, 300, 400) may also have a second 
comparator (250) which protects the power switch (212) 
from a short circuit condition in the circuit (200, 
300, 400).
