Abstract: Representative implementations of devices and techniques provide an exemplary system and method for detection and surveillance of an infectious agent, and particularly an agent that is spread through respiratory aerosols. In an embodiment, the system and method include retrieving a face covering that contains oral and/or nasal, and/or skin secretions and/or skin flora on or within a material of the face covering, removing one or more samples of the material of the face covering that contains the secretions from the face covering, and depositing the one or more samples into a predetermined formulation.

Abstract: Various technologies described herein pertain to enforcing control flow integrity by adding instrumentation when source code is compiled or binary code is rewritten. An indirect call to a control transfer target (e.g., in the source code, in the binary code, etc.) can be identified. Moreover, the instrumentation can be inserted prior to the indirect call. The instrumentation can use a bit from a bitmap maintained by a runtime to verify whether the control transfer target is valid. When an executable image that includes the inserted instrumentation runs, execution can be terminated and/or other appropriate actions can be taken when the control transfer target is determined to be invalid; alternatively, execution can continue when the control transfer target is determined to be valid.

Abstract: An assembly formed by additive manufacturing comprises a top face sheet, a bottom face sheet, and a core structure between the top face sheet and the bottom face sheet, the core structure comprising a plurality of cells, wherein structural elements of the core structure defining the plurality of cells exhibit at least one electrical property in at least one direction varying from at least one electrical property in a second, different direction and at least one structural property in at least one direction varying from at least one structural property in a second, different direction, wherein at least a portion of the structural elements comprises a radar absorbing structure, the structural elements comprising a matrix material and at least one additive dispersed in or on the matrix material. Related radar absorbing structures and related methods of fabricating the radar absorbing structures are also disclosed.

Abstract: An exercise and rehabilitation apparatus for exercising an extremity of a user. The apparatus includes a flywheel having a first side and a second side with a channel in the first side. The channel has a top edge near a planer surface of the first side. A lever, such as a pedal or handle, is adjustable in position and combined with an adjustment member. The adjustment member is movable within the channel between first and second positions. However, the adjustment member cannot be removed from the channel through a slot along the top edge. A locking pin, biased in an extended position, is combined with the adjustment member and is movable between the extended position and a retracted position. The flywheel includes a plurality of openings adapted to receive the locking pin in the extended position in order to secure the adjustment member at a particular location within the channel.

Abstract: A block heater test system for testing continuity in a vehicle's block heater. The block heater test system plugs into the power cord of a block heater to test continuity for the purpose of making sure the block heater can be powered. The block heater test system relies on a battery. So, no other power source is needed; but alternate power sources can be used. An indicator light or audible tone indicates a fault in the block heater or indicates correct operation of the heater depending on the design. The small nature of block heater test system and the weather resistant housing allow for easy use during inclement weather.
