    摘要: Example implementations relate to method and controller for secure management of a rack. The method includes generating a first unique identifier corresponding to a rack profile of the rack hosting rack devices including physical devices and logical devices, in accordance with a rack topology, wherein the rack profile is based on configuration of the rack devices and the rack topology. Further, the method includes receiving information corresponding to the rack profile of the rack from peripheral devices disposed in the rack, wherein the information is based on monitored condition of the rack devices and the rack topology. The method further includes generating a second unique identifier based on the information, and determining variation in the rack profile based on comparison of the first and second unique identifiers. Further, the method includes generating an alert signal in the rack, in response to determination of the variation in the rack profile.

    摘要: In accordance with some embodiments, a light detection and ranging (LiDAR) scanning system includes a light source. The light source is configured to transmit a pulse of light. The LiDAR scanning system also includes a beam steering apparatus configured to steer the pulse of light in at least one of vertically and horizontally along an optical path. The beam steering apparatus is further configured to concurrently collect scattered light generated based on the light pulse illuminating an object in the optical path. The scattered light is coaxial or substantially coaxial with the optical path. The LiDAR scanning system further includes a light converging apparatus configured to direct the collected scattered light to a focal point. The LiDAR scanning system further includes a light detector, which is situated substantially at the focal point. In some embodiments, the light detector can include an array of detectors or detector elements.

    摘要: A frequency tracking method for an ultrasonic electronic cigarette is provided. The method includes enabling start of working of an ultrasonic atomizer and selecting an oscillation frequency range of the ultrasonic atomizer as a frequency scan range according to the natural frequency characteristics of the ultrasonic atomizer. The method further includes selecting N frequency points within the frequency scan range and controlling the ultrasonic atomizer to work at the N frequency points. The method further includes finding out a maximum current value Imax and a minimum current value Imin of the ultrasonic atomizer when working at the N frequency points, and finding out a working frequency fimax corresponding to the maximum current value Imax. The method further includes controlling the ultrasonic atomizer to work at a frequency ftracking=fimax+Δf; and detecting the working current I of the ultrasonic atomizer.

    摘要: Interaction-based ecosystems are presented. Interaction analysis engine analyze media content to derive a set of media features. The engine can then identify one or more interaction objects (e.g., transactions, searches, game play, etc.) based on the set of media features. Relevant interaction objects can then be instantiated as persistent available or active points of interaction readily accessed by a consumer. The consumer need only capture a digital representation of the content via a user device, a smart phone for example. A second set of media features can be derived from the digital representation and the second set of media features can then be used to find the instantiated interactions.
