Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to pair devices to an in-body network. An example apparatus disclosed herein includes a device capability manager to identify remote sensors associated with a candidate medical device, an encryption engine to provide the candidate medical device with hashing instructions to be applied to input values from selected ones of the remote sensors, a measurement engine to acquire input values from local sensors corresponding to the selected ones of the available remote sensors during a measurement schedule, the encryption engine to apply the hashing instructions to the input values from the local sensors, and a pairing engine to authorize the candidate medical device when an encryption key associated with the remote sensors includes a threshold indication of parity with an encryption key associated with the local sensors.

Abstract: Authentication requirements for a user to access a processing system may be dynamically modified based on status information received from sensors coupled to the processing system. The processing system may receive a request for access to the processing system by the user. The processing system determines an authentication policy based at least in part on the status information, and presents authentication requirements to the user based at least in part on the authentication policy.

Abstract: An authentication system authenticates a device based on a detected trajectory of that device within a physical environment. The device includes a wireless transmitter that communicates with sensors distributed throughout the environment. As the device moves throughout the environment, the sensors send location information to an authentication system. The authentication system tracks the trajectory or dynamic location of the device and authenticates the device based on whether the observed trajectory of the device conforms with a predicted trajectory or behavior.

Abstract: A folding wing structure for a missile or other airframe comprises a supporting strut assembly including a leading strut and a trailing strut pivotally secured together at their common ends and pivotally mounted at spaced locations relative to the airframe at their opposite ends, the struts being moveable between a collapsed, storage position in which they are substantially colinear and an expanded, erect position in which they project radially out from the missile. A biassing device urges the struts into the erect position. A double walled, pocket-like wing member of flexible fabric material encloses the strut assembly and conforms substantially to the extended configuration of the struts, and a series of spaced, parallel reinforcing ribs extend chordwise across each wall of the wing member in its erect position between the leading and trailing struts.
