Abstract: A first data accessor acquires a lock associated with a critical section. The first data accessor initiates a help session associated with a first operation of the critical section. In the help session, a second data accessor (which has not acquired the first lock) performs one or more sub-operations of the first operation. The first data accessor releases the lock after at least the first operation has been completed.

Abstract: An electronic computing device for providing a response to an audio query where the response is determined to have a public safety impact. The electronic computing device includes a microphone and an electronic processor. The electronic processor is configured to receive audio data including a speech segment and determine a plurality of possible meanings of the speech segment. Each possible meaning is associated with a probability that the possible meaning is a correct meaning for the speech segment and a first possible meaning is associated with a first probability that is higher than a second probability associated with a second possible meaning. The electronic processor is also configured to determine public safety impact context information of the second possible meaning. The electronic processor is further configured to output a second response associated with the second possible meaning without first outputting a first response associated with the first possible meaning.

Abstract: A device and method for power source based device authentication is provided. The device comprises: a power interface configured to receive power from an external power source; a detector configured to detect a characteristic of the power received by the power interface; and a controller. When the characteristic of the power matches an authorized characteristic, the controller implements an authorization process to provide access to the device. When the characteristic of the power does not match the authorized characteristic, the controller implements a deny-authorization process to deny access to the device.
