  • Patent number: 11175593
    Abstract: An alignment sensor apparatus includes an illumination system, a first optical system, a second optical system, a detector system, and a processor. The illumination system is configured to transmit an illumination beam along an illumination path. The first optical system is configured to transmit the illumination beam toward a diffraction target on a substrate. The second optical system includes a first polarizing optic configured to separate and transmit an irradiance distribution. The detector system is configured to measure a center of gravity of the diffraction target based on the irradiance distribution outputted from a first polarization branch and a second polarization branch. The processor is configured to measure a shift in the center of gravity of the diffraction target caused by an asymmetry variation in the diffraction target and determine a sensor response function of the alignment sensor apparatus based on the center of gravity shift.

  • Patent number: 11177732
    Abstract: A component includes an adaptive estimator. A converter includes a switching rectifier connected to an LCL filter with a converter inductor, a capacitor, and grid inductor connected to a voltage source through a conductor with unknown inductance. Current of the converter inductor is input to the adaptive estimator which includes an ideal LCL filter model that generates, using a simple filter, a desired dynamic behavior of the converter and LCL filter and a disturbance compensator. An LCL steady-state (“SS”) compensation models a steady-state effect of the LCL filter and conductor. Output of the adaptive estimator is subtracted from output of the LCL SS compensation to form a disturbance estimate, which is summed with a feedback loop output of the converter to form a voltage control signal that controls switching of the switching rectifier. The voltage control signal is summed with the disturbance estimate and is input to the adaptive estimator.

  • Patent number: 11168535
    Abstract: A single-set anti-extrusion ring has a plurality of ring segments with a mating face on each end. Each mating face has a 3-dimensionally curved topology and the first mating face is a mirror image of the second mating face so the ring segments fit together to form and anti-extrusion ring without gaps in an unexpanded condition, and no straight path through the anti-extrusion ring in an expanded condition.

  • Patent number: 11168537
    Abstract: A fluid-pressure-set uphole end for a hybrid straddle packer has a multicomponent mandrel with a fixed piston and a multicomponent sliding sleeve with a sliding sleeve piston housing that houses the fixed piston. The multicomponent sliding sleeve reciprocates within a limited range on the multicomponent mandrel in response to fluid pressure pumped into a central passage of the multicomponent mandrel. An anti-set spring constantly resists relative movement between the multicomponent mandrel and the multicomponent sliding sleeve and returns the uphole end to a run-in condition when fluid pressure in the central passage is released.

  • Patent number: 11159169
    Abstract: Analog circuits are often non-linear, and the non-linearities can hurt performance. Designers would trade off power consumption to achieve better linearity. An efficient and effective calibration technique can address the non-linearities and reduce the overall power consumption. A dither signal injected to the analog circuit can be used to expose the non-linear behavior in the digital domain. To detect the non-linearities, a counting approach is applied to isolate non-linearities independent of the input distribution. The approach is superior to and different from other approaches in many ways.

  • Publication number: 20210321257
    Abstract: Multi-RAT UEs currently have 2 independent paths to authenticate with HSS (e.g., via the MME or the 3GPP AAA Server causing repeated authentication messages to HSS). The use of one unified authentication path between the UE and HSS for Small Cell and Wi-Fi authentication is described. First, a new 3GPP EPC-TWAN interworking architecture has the MME manage all the authentication requests from multi-RAT UEs. Second, new unified authentication procedures are added, which allow the ISWN-based multi-RAT UE to be authenticated directly with the HSS, irrespective of its current access network (TWAN or HeNB). Third, new fast re-authentication procedures for Inter-RAT handover scenarios are done. Finally, the needed extensions to the various standard protocol messages to execute the authentication procedures are described.

  • Publication number: 20210258976
    Abstract: A Service Capability Exposure Function can be added to the UE (U-SCEF). The U-SCEF may be part of the UE's operating system (OS) and expose API's to applications that allow these applications to schedule data plane communications such as periodic sensor measurements or a firmware download. The U-SCEF communicates with an EPC Interworking Service that resides in the mobile network operator's (S)Gi-LAN. The EPC Interworking Service serves as an interface between the U-SCEF and the service capabilities that are exposed by the MNO via the SCEF. The U-SCEF may provide the EPC Interworking Service with information about the UE's anticipated communication schedule and mobility status. The EPC Interworking Service uses the services that are exposed by the SCEF to determine the optimal times for the UE to communicate, an optimal mobility management configuration, etc.

  • Publication number: 20210243116
    Abstract: The present technology pertains to a group-based network policy using Segment Routing over an IPv6 dataplane (SRv6). After a source application sends a packet, an ingress node can receive the packet, and if the source node is capable, it can identify an application policy and apply it. The ingress node indicates that the policy has been applied by including policy bits in the packet encapsulation. When the packet is received by the egress node, it can determine whether the policy was already applied, and if so, the packet is forward to the destination application. If the egress node determines that the policy has not be applied the destination application can apply the policy. Both the ingress node and egress nodes can learn of source application groups, destination application groups, and applicable policies through communication with aspects of the segment routing fabric.

  • Publication number: 20210219132
    Abstract: Provisioning multiple artificial reality devices can be accomplished through network communications between a device distributor, an administration system, a provisioning device, and the artificial reality devices. The device distributor can provide, to the administration system, a list of artificial reality devices corresponding to a particular organization. A provisioning device can sign into an account on the administration system and receive the list. The provisioning device can then scan for wireless connectivity with the listed artificial reality devices and can make a wireless connection with any artificial reality devices that respond and that are on the list. The provisioning device can then send these devices credentials for a local WiFi network. The artificial reality devices can automatically, upon receipt of the credentials, connect to the administration system to obtain the software update and/or the configuration data.
