Abstract: An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

Abstract: A method for accessing secured data stored in an eID card using combined MoC and MRZ technology is provided. The eID card receives from a card reader an extracted biological feature that is obtained by a biometric device extracting a biological feature of a user. When the extracted biological feature matches a pre-stored biometric template, the eID card permits the card reader to acquire a digital access code stored therein the content of which is identical to a printed MRZ code on the eID card. Upon receipt of the digital access code, the card reader establishes secured communication with the eID card to access the secured data that is stored in the eID card.

Abstract: A system adapted to interact with an electronic card includes a server and an electronic lock device. The electronic lock device is configured to switch between a locked state and an unlocked state.

Abstract: Aspects described herein disclose devices, systems, and methods for use in contexts such as minimally invasive surgery (MIS). Methods of use of radio frequency (RF) techniques for improved nerve detection in association with an ultrasound detection system are described. The methods include the use of RF echoes in the detection of tissue dependent features. The methods also include use of an RF classifier to reduce false positives. System dependent features are accounted for through use of a calibration spectrum or through non-parametric model estimation using machine learning.

Abstract: A receiver generates a stream of digital samples from an analog electrical signal that represents data conveyed to the receiver over a communication channel, where the stream of digital samples comprises current samples corresponding to a current timepoint, previous samples corresponding to a timepoint earlier than the current timepoint, and subsequent samples corresponding to a timepoint later than the current timepoint. The receiver generates previous, current, and subsequent phase offset signals based on the previous, current, and subsequent samples, respectively. The receiver uses the previous phase offset signal to adjust clock frequency and clock phase of the current samples, thereby resulting in current adjusted samples. The receiver adjusts clock phase of the current adjusted samples based on any one of the previous, current, and subsequent phase offset signals. In some examples, receiver adjusts the clock phase of the current adjusted samples based on the subsequent phase offset signal.

Abstract: A password input and identification system includes a one-button password input component and a controller. The one-button password input component generates a series of trigger signals in response to a series of triggers that correspond to a series of user-input digits. The controller determines a value of each of the user-input digits by counting a number of the trigger signal(s) that correspond(s) to the user-input digit to serve as the value of the user-input digit. The controller compares the user-input digits with the predetermined password after the input of the user-input digits is finished, and performs a predetermined action when the user-input digits match the predetermined password.
