Abstract: An optical scanning system including a radiating source that outputs a light beam, a time varying beam reflector that reflects the light beam through a scan lens towards a transparent sample, a focusing lens configured to be irradiated by light scattered from the transparent sample, and a detector that is irradiated by the light scattered from the transparent sample. The detector outputs a signal that indicates an intensity of light measured by the detector. None of the light scattered from the transparent sample is blocked. The light scattered from the transparent sample is scattered from the top surface of the transparent sample, the bottom surface of the transparent sample, or any location in between the top surface of the transparent sample and the bottom surface of the transparent sample.

Abstract: Described herein are systems configured for inter-band carrier aggregation. Systems include a multiplexing circuit having a switching network and diplexers wherein the switching network is configured to share inductors between multiple paths of the multiplexing circuit. The filters can be designed so that when operated simultaneously (e.g., during multi-band operation) the same inductance can be used allowing the switching network to switch in a particular inductance into the path. The described systems can include an inductance that is coupled to an output port so that when operating in single-band mode, the different paths share the same inductance. Relative to other solutions, the described systems can improve performance (e.g., reduce insertion loss), reduce the number of components in the associated module, reduce manufacturing costs, and the like.

Abstract: An optical scanning system includes a radiating source capable of outputting a light beam, a time varying beam reflector that is configured to reflect the light beam through a scan lens towards a transparent sample at an incident angle that is not more than one degree greater or less than Brewster's angle of the transparent sample, and a focusing lens configured to be irradiated by light scattered from the transparent sample at an angle that is normal to the plane of incidence of the moving irradiated spot on the transparent sample. A first portion of the light beam is scattered from a first surface of the transparent sample and a second portion of the light beam is scattered from a second surface of the transparent sample. A spatial filter is configured to block the second portion of the light beam scattered from the second surface of the transparent sample.

Abstract: An optical scanning system includes a radiating source capable of outputting a light beam, a first time varying beam reflector that is configured to reflect the light beam through a scan lens towards a transparent sample at an incident angle that is not more than one degree greater or less than Brewster's angle of the transparent sample, and a second time varying beam reflector that is configured to reflect the light beam reflected from the transparent sample after passing through a de-scan lens onto a phase retardance detector. The output of the phase retardance detector is usable to determine if a defect is present on the transparent sample. The first time varying beam reflector causes a first phase retardance of the light beam and the second time varying beam reflector causes a second phase retardance of the reflected light beam in the opposite direction of the first phase retardance.

Abstract: A customer care system that uses machine learning to surface relevant information for resolving customer issues regarding cellular network service is provided. The system receives a set of incoming data that includes current information of a cellular network. The system applies the set of incoming data as input to a machine learning model to produce a set of predicted conclusions. The machine learning model is trained by using one or more sets of orthogonal datasets that includes historical information of the cellular network. The system maps the set of predicted conclusions to a remedial action and performs the remedial action to effectuate a change in the cellular network.

Abstract: Cellular networks regularly operate with trusted devices, which typically are trusted because of the integration of a SIM card therewith. Untrusted devices typically do not interface with a SIM card, and rely on user input through traditional user interfaces for authentication. Recently, the use of hands-free, always-on digital assistant devices have become more common. Such devices typically have only a voice user interface that may be used by a number of people in close proximity to the device. Particular problems arise in such a scenario when a user wants to access a secure service that requires user authentication. Such problems are addressed with multiple techniques described herein.

Abstract: A latch mechanism is provided that includes a housing, a cap, and at least one indicator. The cap may include a central axis and may be mounted for selective rotational movement relative to the housing about the central axis between a latched position and an unlatched position. The at least one indicator may be interposed between the cap and the housing, such that the cap is in covering relationship to at least a portion of the at least one indicator. The at least one indicator may also be mounted for radial movement outwardly from the central axis relative to the cap as the cap is rotated from the latched position to the unlatched position such that the cap is no longer in covering relationship to the portion of the at least one indicator.

Abstract: A three-dimensional (3D) microscope for patterned substrate measurement can include an objective lens, a reflected illuminator, a transmitted illuminator, a focusing adjustment device, an optical sensor, and a processor. The focusing adjustment device can automatically adjust the objective lens focus at a plurality of Z steps. The optical sensor can be capable of acquiring images at each of these Z steps. The processor can control the reflected illuminator, the transmitted illuminator, the focusing adjustment device, and the optical sensor. The processor can be configured to capture first and second images at multiple Z steps, the first image with the pattern using the reflected illuminator and the second image without the pattern using one of the reflected illuminator and the transmitted illuminator.
