    Abstract: An exoskeleton comprising a plurality of support structures, and a plurality of joint mechanisms each joint mechanism rotatably coupling at least two of the plurality of support structures. A sensor suite discrepancy detection system can be operable to interrogate the suite of sensors within the exoskeleton, and can comprise a plurality of sensor groups, each associated with a respective joint mechanism, and each comprising a plurality of sensors from a suite of sensors. A controller can be configured to recruit at least one substitute sensor from a first sensor group of based on an identified discrepancy between the sensor output data of at least two sensors within the first sensor group and a target sensor within the first sensor group, and to execute a remedial measure associated with a safety mode of the exoskeleton for safe operation of the exoskeleton.

    Abstract: An exoskeleton operable to prevent unsafe operation can comprise a plurality of joint mechanisms and a plurality of sensors comprising configured to generate sensor output data associated with at least two joint mechanisms. The exoskeleton can comprise a controller configured to receive the sensor output data; combine the sensor output data; and determine whether the combination of the sensor output data from the first and second sensors satisfies an error condition in relation to at least one defined criterion. The existence of an error condition can be indicative of an anomalous operating state of the exoskeleton, such as a malfunction or an (impending) anomalous kinematic movement. The controller can also combine command signals to be transmitted to two or more joint mechanisms to determine another anomalous operating state to prevent unsafe operation. Associated software and methods are provided.

    Abstract: A stiffening element to provide variable resistance to movement between a pair of members at a joint. The stiffening element comprises a filler with particles flowable in a bladder. A pressure source is coupled to the bladder to vary a pressure within the bladder and collapse the bladder. Collapsing the bladder varies a flow characteristic of the filler within the bladder, Varying the flow characteristics of the filler varies resistance of the bladder to movement of the bladder, and thus a pair of movable members and the joint.

    Abstract: A system for neutralization of a target aerial vehicle comprises one or more counter-attack unmanned aerial vehicles (UAVs) and an aerial vehicle capture countermeasure tethering the counter-attack UAV(s) to a structure or ground. The counter-attack UAV(s) are operable to capture and neutralize the target aerial vehicle with the aerial vehicle capture countermeasure (e.g., a net). The system can comprise an on-board aerial vehicle detection system, and/or an external aerial vehicle detection system each having at least one sensor configured to detect the target aerial vehicle while in flight. The counter-attack UAV(s) and the associated detection systems may be autonomously operated for detecting and neutralizing a target aerial vehicle. The aerial vehicle capture countermeasure can be moved from a stowed position to a deployed position in response to coordinated flight of the counter-attack UAV(s). Associated methods and systems are provided.

    Abstract: A technology is described for managing and securing a software version history for a device using a blockchain. An example method can include receiving device information for a device configured to receive software updates, where a device history for the device can be contained in a blockchain distributed among multiple network nodes. The device information can be validated against the device history contained in the blockchain to confirm an identity of the device, and a software update can be initiated for the device. An indication that the software update was installed on the device can be received and a block can be generated to include information for the software update installed on the device. The block can be sent to the network nodes configured to determine acceptance of the block and append the block to the blockchain when the block is accepted.

    Abstract: A robotic end-effector to provide magnetic and mechanical finger grip. The end-effector has one or more magnets coupled to a palm, each of the one or more magnets having a magnet face to magnetically attach to a ferromagnetic object. The magnet face(s) define(s) a magnetic engagement surface with the magnet and the palm disposed on a proximal side of the magnetic engagement surface. A finger is pivotally coupled to the palm to grip the ferromagnetic object or another object. The finger has a deployed configuration wherein the finger is disposed distally with respect to the magnetic engagement surface and opposes the palm or the magnet face to grip the ferromagnetic object or other object. The finger has a retracted configuration wherein the finger is disposed proximally with respect to the magnetic engagement surface along with the magnet and the palm, and wherein the magnetic face forms an outermost contact surface.
