Abstract: An RFID system comprises an array of antennas each configured to emit a plurality of beams in different directions. The beams of each pair of adjacent antennas are directed towards one another and overlap. A pair of adjacent antennas transmits simultaneously and the overlapping beams interfere to create an interference pattern. An RFID reader controls the relative phase and/or frequency of the beams to move the interference pattern to read an RFID tag within the moving pattern. As the chance of a RFID tag responding to an emitted beam generally increases with signal strength of the reader beam an area of constructive interference means that RFID tags in that region are more likely to respond to the signal. The system can cover a large proportion of the area below ceiling-mounted antennas, where cover generally means that RFID tags in that area will be successfully read.

Abstract: A method for performing segmentation on CT image data of a spine is provided. The method includes retrieving the CT image data of the spine, detecting an estimated position of at least four pedicle regions associated with a plurality of vertebras, determining a pose for each of at least two vertebrae. The method further includes performing a first segmentation process on the CT image data with a shape model to generate a first segmentation and performing a second segmentation process on the CT image data using a first neural network to generate a second segmentation of the at least two vertebrae. The method also includes mapping the shape model to the second segmentation, applying landmarks from the shape model to the second segmentation using the mapping, and overlaying a segmentation mask based on the second segmentation over the CT image data.

The techniques enable useful, practical approximations to the ideal modulating current to be determined.

Abstract: Systems for, and methods of, detecting an attack on an optical communication channel are presented. The techniques can include sending, from a sender to a receiver, and over the optical communication channel, an optical signal, where the optical signal includes a classical optical signal representing first information and a quantum optical signal representing second information. The techniques can include detecting, by the receiver, third information from at least a portion of the quantum optical signal and sending, by the receiver to the sender, the third information. The techniques can include determining, by the sender, an indication of an attack on the optical communication channel based on at least a portion of the second information and the third information. The techniques can include triggering an alarm based on the determining.

Abstract: A multi-factor user authentication framework using asymmetric key includes a host device, a user agent, a gesture system, and an authentication system. The multiple factors include a user credential as well as a user gesture that indicates that the user is present. The user interacts with the user agent via the host device in order to obtain access to something for which user authentication is needed. The authentication system maintains the user credentials, which are provided to authenticate the user in response to the authentication system determining that the user is present (which can be determined in different manners, such as using a personal identification number (PIN), biometric information regarding the user, geographic location of the gesture system, etc.). The user agent, gesture system, and authentication system can be implemented on the same device (e.g., the host device), or alternatively implemented across one or more different devices.

Abstract: A latch system includes an actuation module having first and second actuation mechanisms. The first actuation mechanism includes a first handle, a lock tab and an inner rod coupled together. The second actuation mechanism includes at least one second handle, a conversion block and an outer rod coupled together with the outer rod and the conversion block each having a slot. At least one latch module has a retractable latch. A control cable connects the conversion block and the latch module such that rotation of the conversion block in a first direction retracts the latch. A lock is operably engagable with the lock tab to selectively allow and prevent rotation of the inner rod. Rotation of the inner rod in the first direction rotates the conversion block. Rotation of the outer rod in the first direction rotates the conversion block without rotating the inner rod.

Abstract: A latch system includes an actuation module having first and second actuation mechanisms.

Abstract: A system for creating an account with an identity provider. The system receives a request to create an identity provider account with the identity provider for use in logging onto a third-party system. The system generates one or more display pages for providing an integrated-consent user experience. The integrated-consent user experience includes a display page for collecting both new-account information and scope-of-consent information whereby a user consents to share information with the third-party system. After the user provides the new-account information that includes user credentials for the identity provider account and consents to share account information of the identity provider account with the third-party system, the system creates the identity provider account for the user.

Abstract: A method and system for authenticating a user is provided. In some embodiments, a security system determines whether the time since the last authentication was successful is less than a recycle telephone number period (e.g., the minimum time before which a telephone number might be assigned to a new user). If the time is less than the recycle telephone number period, the security system performs a primary authentication of the user based on a telephone number received from the user. When the primary authentication is successful, the security system indicates that the user has been authenticated. When the time is not less than a recycle telephone number period, the security system performs a secondary authentication of the user. When the secondary authentication is successful, the security system indicates that the user has been authenticated.
