Patent EP-0840453-A2 (EP)
Inventor: BLAKE TERENCE G W
IPC: H03K19/003
Filed: 1997-10-28
Abstract: An output buffer includes a pair of P-channel transistors and two cascode pull-down N-channel transistors to drive an output node. The output pull-up transistor (Q6) has the gate thereof connected through a P-channel control transistor (Q5) to an input driving signal. The control signal is isolated from the output node by a shunt P-channel transistor (Q4) which only conducts during overvoltage conditions. During normal operation, the control transistor (Q5) is maintained in a conductive state to allow the gate of the output pull-up transistor (Q6) to be pulled high and low. During an overvoltage condition, the shunt P-channel transistor (Q4) connected between the output node and the control transistor is turned on to effectively turn off the control transistor. The output P-channel transistor (Q6) is protected from excess voltages across the gate oxide when initially coming out of the hiZ state with a logic high signal on the input. This is facilitated by pulling the gate thereof low to a voltage above ground and then pulling the gate fully to ground when the voltage on the output node falls to below the supply voltage. This is provided by a NAND gate structure (120,122,124,128) that disposes a limiting P-channel transistor (128) in series with the gate of the P-channel pull-up transistor (Q6) to prevent it from going to a full logic low level. When the voltage on the output is pulled down by the shunt P-channel transistor (Q4), this will then bypass the limiting P-channel transistor (128) in the NAND gate and pull the gate of the P-channel pull-up transistor (Q6) down to the full low logic level.

Abstract: A system (10) for virtually modeling a physical system having immovable and movable objects includes at least two video cameras (20-24, 62), each of the video cameras being configured to provide a sequence of images. An image processing system (60) extracts modulated infrared signals from the sequence of images to identify the spatial location of objects (55, 70, 75) using information obtained from both visible light images and infrared images. With this information, a virtual reality modeling system constructs a virtual reality model. Infrared pointers that direct modulated infrared spots having a unique identification against surfaces can be used for surveying, while active (50, 57) or passive (51) infrared tags can track movable objects for virtual reality modeling.

Abstract: In a distributed object application builder apparatus an object definition is filtered to
determine the information needed and provided by an object. The information needed is
represented by plugs, and the information provided by sockets. Each part (representing a
run-time instance of an object) in the builder has plugs and sockets that are interconnected
to other parts in order to define a distributed object application program. At run time, actual
instances of objects will be substituted for the parts. A method of determining the plugs of
an identified part begins by retrieving the interface (object definition) that corresponds to
the part. Once this interface has been retrieved, the plugs of the part may be identified by
determining the object-valued attributes of the retrieved interface, by determining the
operations from the retrieved interface that require one object-valued argument, and by
retrieving the factory argument list from the factory method for the object. Together, these
attributes and arguments constitute the plugs of the part. Sockets of a part may be
determined similarly, and include the attributes of the interface and the operations that
return an object-valued result. The plugs of a part may be determined based upon their
matching with a previously chosen socket. Similarly, it a plug is chosen first from a part,
this chosen plug may be matched with a socket of another part. Sockets may be determined
in a recursive manner using "tunneling". A distributed object application program may be
constructed by choosing a first part, filtering its interface to determine its plugs and
sockets, and then choosing and filtering the interface of a second part. Once plugs and
sockets have been determined, they may be connected in order to at least partially define a
distributed object application program. The filtering may take place within a visual
application builder using a graphical user interface to select and connect parts.

Abstract: This invention provides a fast framing device that
processes a stream of bytes and generates a signal for
every byte clock that indicates whether a selected
Asychronous Transfer mode cell boundary may be valid. The
fast framing device generates a Cyclical Redundancy Code
(CRC) corresponding to each byte from a input byte stream.
The generated CRC is processed by an XOR tree that
produces an output equivalent to processing the CRC code
through five cycles of an CRC generator. The result of
the XOR tree is exclusive with a hexidecimal number "AC"
or 0xAC. The result of the XOR tree and the XOR gate is
delayed by five cycles and then compared with the CRC
generated during the fifth byte clock. The compared
results indicates whether the prior five bytes may be a
valid ATM cell header.

Abstract: In accordance with the invention, a continuous chirped fiber Bragg grating is
made by fabricating a continuous chirped phase mask and using the mask to write a
Bragg grating on a parallel fiber. The chirped phase mask is made by exposing a
photoresist-coated mask substrate to two interfering beams: one a collimated beam and
the other a beam reflected from a continuous curved mirror. After etching, the resulting
phase mask can be used to write a chirped fiber grating having a continuously varying
grating period without physical modification of the fiber. The resulting fiber grating has
a widened bandwidth and uniform dispersive delay characteristics useful for dispersion
compensation in critical telecommunications applications.

Abstract: An optical transmission system allows for the
remote determination of the output power of each
carrier for each repeater. The optical
transmission system includes two terminals, an
optical path that transmits a plurality of optical
signals between the two terminals, and a plurality
of repeaters spaced along the optical path. At
least one of the terminals generates a first line
monitor signal and a second line monitor signal.
The second line monitor signal is delayed by a
round trip delay from the terminal to a repeater
at which the output power is desired to be
measured. The terminal then transmits the first
line monitor signal on the optical path. Each
repeater in the transmission system generates a
return line monitor signal in response to
receiving the first line monitor signal and
transmits the return line monitor signal on the
optical path.
