Abstract: Unique methods and systems are introduced herein for the determination of unique spatial light modulator based optical signatures of intrinsic and extrinsic scattering surface markers. These techniques can be used to authenticate semiconductor components and systems at various stages during the manufacturing process by measuring and cross correlating the surface marker's unique optical signature. In addition, these techniques can be used with extrinsic surface markers which are added to existing hardware (e.g. containers, locks, doors, etc.). These markers can then be measured for their unique optical signatures, which can be stored and used at a later time for cross-correlation to authenticate the surface marker and verify the hardware's provenance.

Abstract: Methods and systems are provided for improving engine knock tolerance, in particular when rapidly ramping in LP-EGR from low levels of EGR. Until a desired LP-EGR rate is achieved, fuel may be delivered as a split injection with at least an intake stroke injection and a compression stroke injection to compensate for the transport delay in EGR filling the intake system. Subsequently, single fuel injection may be resumed.

Abstract: A weldment member for a gas turbine engine including a forward welding member and an aft welding member. The forward welding member has an annular shape with a forward welding face formed at one end. The forward welding face has a forward radiographic marking hole formed therein. The aft welding member has an annular shape with an aft welding face formed at one end. The aft welding face has an aft radiographic marking hole formed therein. The forward welding face is aligned with the aft welding face and the forward radiographic marking hole is angularly offset from the aft radiographic marking hole.

Abstract: A case is provided for a portable Radio Frequency (RF) communications device having an RF antenna. The case includes a base and a plurality of walls, extending from the base. The base and the plurality of walls have requisite dimensions to receive a portable Radio (RF) having an outer surface with a first portion and a second portion. First dielectric characteristics adjacent to the first portion having a relatively low effect on a frequency characteristic of an RF antenna arrangement and second dielectric characteristics adjacent to the second portion having a relatively high effect on the frequency characteristic of the RF antenna arrangement. When the communications device is disposed in the case, the case is adapted to cover part of the first portion of the communications device so as to cause a dielectric parameter adjacent a part of the first portion of the communications device to be relatively high, and a dielectric parameter adjacent the second portion to be relatively low.

Abstract: Embodiments of the systems described herein can implement one or more visitor tearing processes. Visitor tearing can include, among other things, one or more processes by which multiple visitors that may appear to be the same visitor may be separated into different visitor profiles due to the leveraging of one or more unique persistent identifiers.

The case has a base, dimensioned to fit a back of the RF communications device; and a plurality of walls, extending from the base and dimensioned to fit corresponding walls of the RF communications device. The case is configured to cover part of the first portion so as to cause a dielectric parameter adjacent a part of the first portion to be relatively high.

Abstract: Allowing an entity managed device to access a tenant associated with the e on a public cloud service while preventing the device from accessing one or more other tenants on the cloud service. A method includes, at the cloud service, obtaining policy from the entity with respect to tenant access. The method further includes, at the cloud service, receiving a request from the entity managed device to access a tenant at the cloud service. The method further includes granting or denying the access request based on the policy obtained from the entity.

Abstract: Automated device discovery of pairing-eligible devices for authenticating an unidentified user of a computing device is provided. When the user initiates a login on the computing device on which the user's identity is not known, an automated pairing-eligible device discovery authentication system interrogates a resource (e.g., subnetwork router, calendaring server) for identifying pairing-eligible devices that may be used as a second factor for authentication. A list of the pairing-eligible devices is presented to the user on the computing device. Upon selection of a pairing-eligible device to use as a second factor to verify the user's identity, the user's identity is determined, and a notification is sent to the selected pairing-eligible device for enabling the user to verify his/her identity using a second factor. Upon completion of an authentication challenge on the selected pairing-eligible device, authentication of the user is completed, and a signed token is sent to the computing device.

Abstract: Methods and systems are provided for improving combustion stability, in particular during transient operations such as tip-out to lower load conditions, when EGR is being purged. Until a desired LP-EGR rate is achieved, fuel may be delivered as a split injection with at least an intake stroke injection and a compression stroke injection. Subsequently, single fuel injection may be resumed.

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.
