Abstract: A method and system referred to as PALM (Patterning by Adhesive of Large Relief Three-Dimensional Microstructures) with large reliefs exceeding 1 ?m and being as large as 100 ?m. The microstructures can be either deterministic (such as microprisms), or random (such as diffusers), the first obtained by copying an original supermaster, and latter obtained by copying a laser speckle pattern. The master process entails copying a supermaster into the form of the microstructure constituting a pattern on the patterning cylinder (called a drum), to be then continuously multiplied in the PALM system, in a continuous roll-to-roll web process. The latter method, together with the related system, is the subject of this invention. The rolls continuously repeat the master pattern, copying by adhesive with large viscosity on acrylic (hybrid) as well as by a monolithic process. The monolithic process can be accomplished using temperature and pressure, or by UV-cured polymerization.

Abstract: An information carrier in a preferred embodiment is worn like a dog-tag and carries data such as medical information. The tag operates wirelessly, communicating with a nearby reader which interrogates the tag with a selected combination of RF signal frequencies. Extremely long term battery usage is achieved by connecting the battery in the tag only when the proper combination of RF signals, each at least at a minimum threshold power level, is received at the tag to produce a trigger voltage in activation logic to close a solid state switch. After a sequence of communications between the reader and the tag is then completed to transfer selected data from the memory, the battery is again disconnected to preserve battery energy for very long periods of time. The battery may be slowly recharged by ambient energy using a scavenging antenna array.

Abstract: A system and method that will improve QoS (Quality of Service) of wireless video transmission systems. This is done by “in-fly” monitoring of BER by periodically transmitting “test images”, which images are known to the RF-receiver (Rx). BER can be automatically computed, within a related BIT (Built-in-Test) procedure that is also the subject of this invention. This allows predictions of a proper increasing, or decreasing of bandwidth OVH-level, in order to compensate for a BER-change. BER computation is facilitated by distinguishing video frames based on whether they depict new spatial events or related temporal events. Another subject of this invention is a motion-based pre-ATR method that is an introduction to common ATR, or pattern recognition methods. Yet another subject of this invention is a process of implanting error correcting bits into a payload, in the form of imperceptible watermarks.

The quantum-imaging system can also function as a photon spectrometer and can be configured to measure photon energies with high energy resolution such as, for example, 1% of photon energy.
