Abstract: Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away from the printed part, resulting in a part having surface cavities.

Abstract: Implantable medical devices have zones of high in vivo stability that are adjacent to zones of relatively low in vivo stability, so that when these medical devices are implanted into a host, the zones of low in vivo stability degrade first and allow the formation of independent segments of relatively intact high in vivo stability bands that are sufficiently small that they may pass from the host in a non-harmful manner.

Abstract: A physically unclonable function (PUF) includes an array of differential PUF bits arranged in rows and columns, wherein each differential bit is located at an intersection of a row and a column, and includes a first PUF cell coupled to a corresponding first bit line and first source line and a second PUF cell coupled to a corresponding second bit line and second source line. The PUF includes a source bias transistor coupled between each corresponding first source line and a first power supply terminal and between each corresponding second source line and the first power supply terminal, wherein a gate electrode of each of the source bias transistors is coupled to a second power supply terminal, and a corresponding set of margin transistors coupled in parallel with each source bias transistor, wherein a gate electrode of each margin transistor is coupled to receive a corresponding margin setting control signal.

Abstract: A data processing system and method for generating a digital code for use as a physically unclonable function (PUF) response is provided. The method includes activating a plurality of word lines for a read operation. A first bit line is coupled to a first input of a comparator during the read operation. A second bit line is coupled to a second input of the comparator during the read operation. A current is generated on each of the first and second bit lines. The currents on the first and second bit lines are converted to voltages. The voltage on the first bit line is compared to the voltage on the second bit line. A logic bit is output from the comparator as part of the digital code, a logic state of the logic bit is determined in response to the comparison. By selecting multiple word lines to determine a PUF response, noise immunity is improved.
