Abstract: One example method includes providing temporary access to a computing system and to providing temporary access as a service. The features of a temporary access can be defined by an entity and a user may be able to obtain a token that includes these features, which may be embedded in the token as claims. The user's access is then controlled in accordance with the embedded claims. The temporary access as a service can be federated. The token may include trust levels and tolerance limits. Further, aspects of the temporary access can be monitored and/or changed. Adjustments to trust levels can be automated or manually performed. Further trust for specific users can be gained or lost over time based on at least previous accesses.

Abstract: Described herein are embodiments directed to a particle repelling helmet having particle mitigation system that keeps dust particles from going into the interior of the helmet. The helmet comprises a face vent that provides an unobstructed pathway between an external environment and a wearer's eyes, nose and mouth. A spacer arrangement connected to an inner side of the helmet provides a channel between the wearer's head and the inner helmet side. A fan blows air through the helmet, across the wearer's head and out the face vent and head receiving opening in the bottom of the helmet. Electrodes disposed along the edge of the face vent produce an electrostatic barrier that spans the face vent thereby further preventing charged dust from going into the helmet. The helmet can also comprise an ionizer that generates ions, which charges neutral dust particles that can be blocked by the barrier.

The actuator member is coupled to the struts of the support structure and is configured to incrementally move the support structure between the radially compressed state and the radially expanded state and to automatically lock the support structure in a particular state. The leaflets are coupled to the commissure struts of the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve. The sealing material is coupled to the support structure and includes a plurality of commissure extensions that wrap around and are coupled to the commissure struts of the support structure.

Abstract: An improved bolt and bolt carrier with integral gas key having an extension nozzle threadedly secured and pinned to the gas key for use with a direct gas operated firearm is provided. The extension nozzle is designed to receive a portion of the host firearms gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pins annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end and an extractor recess. The extractor recess is constructed to accommodate an enlarged extractor claw while not undercutting the bolt lugs adjacent thereto. The extractor engages approximately 57% more of a seated ammunition cartridges rim as compared to some prior art AR15/M16 type extractors used with automatic firearms chambered in 6.8SPC. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

Abstract: Disclosed active reflector apparatus and methods that inhibit self-induced oscillation. One illustrative apparatus embodiment includes an amplifier and an adjustable phase shifter. The amplifier amplifies a receive signal to generate a transmit signal, the transmit signal causing interference with the receive signal. The adjustable phase shifter modifies the phase of the transmit signal relative to that of the receive signal to inhibit oscillation. A controller may periodically test a range of settings for the adjustable phase shifter to identify undesirable phase shifts prone to self-induced oscillation, and may maintain the phase shift setting at a value that inhibits oscillation.

Abstract: Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Some embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. The device comprises a capsule sized to be swallowed and pass through the intestinal tract. The capsule can include at least one guide tube, one or more tissue penetrating members positioned in the guide tube, a delivery member, an actuating mechanism and a release element. The release element degrades upon exposure to various conditions in the intestine so as to release and actuate the actuating mechanism. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.
