Abstract: Embodiments of a system, a machine-accessible storage medium, and a computer-implemented method are described in which operations are performed. The operations comprising receiving a plurality of image frames associated with a video of an endoscopy procedure, generating a probability estimate for one or more image frames included in the plurality of image frames, and identifying a transition in the video when the endoscopy procedure transitions from a first phase to a second phase based, at least in part, on the probability estimate for the one or more image frames. The probability estimate includes a first probability that one or more image frames are associated with a first phase of the endoscopy procedure.

Abstract: User authentication based on cognitive profiling. First, usage by a person of one or more computerized devices is automatically and continuously tracked. A cognitive profile of the person is automatically and continuously generated based on the tracked usage. Responsive to a request for authenticating an identity of the person, a cognitive question is automatically generated based on the cognitive profile, and is presented to a user professing to be the person. An answer to the cognitive question is received from the user. Finally, the identity of the person is automatically authenticated when the answer to the cognitive question is determined to be correct.

Abstract: Presented herein are devices, methods and software products for dynamically adjust a Transmitter Power Output (TPO) of a mobile wireless device's transmitter by computing a first geolocation of the mobile wireless device based on geolocation data received by the mobile wireless device, obtaining proximity attribute(s) of fixed location wireless access point(s) comprising at least a predefined second geolocation of the respective wireless access point, computing a minimal TPO value for the transmitter according to a distance between the first geolocation and the second geolocation of each wireless access point located within a transmission range of a transmitter of the mobile wireless device, selecting a preferred wireless access point requiring a lowest minimal TPO value and adjusting the TPO of the transmitter to the lowest minimal value. Wherein the minimal TPO value is sufficient for the respective wireless access point to reliably receive each message transmitted by the transmitter.
