Abstract: Aspects of the disclosure relate to a radio frequency phase shifter. An example includes an amplification stage to produce an amplified voltage, the amplification stage having a first amplifier with a first input coupled to a first output of a hybrid coupler and a second amplifier with a complementary second input coupled to a complementary second output of the hybrid coupler. A vector modulation stage coupled to the amplification stage receives the amplified voltage and produces a modulated vector, the vector modulation stage has an in-phase section and a quadrature section to control the phase of the modulated vector in response to a phase control signal. A varactor coupled across the first input and the second input of the amplification stage adjusts the capacitance between the first input and the second input in response to a capacitance control signal.

Abstract: The present disclosure relates to processing operations configured for intelligent management of a synchronization interval usable to synchronize data for an application/service between local data storage and distributed data storage. A classification prediction for a synchronization interval may be generated that is used as prediction for modifying the synchronization interval when a plurality of computing devices, linked to one or more user accounts, are used to access content. For instance, a suggestion is made as to whether a synchronization interval should be made faster, slower or even remain unchanged when a user account is accessing content. This may occur based on analysis of contextual factors described herein, thereby enabling a synchronization prediction component to make a best possible prediction for setting a synchronization interval. Artificial intelligence processing may be trained to generate the classification prediction for a synchronization interval.

The force of the plunger assembly moving forward may disperse the tranquilizer fluid into the living body through at least one of the plurality of holes. The plunger stop can prevent the piston from exiting the tip.

Abstract: Technology is described herein for facilitating a user's interaction with a digital ink document. The technology internally represents the ink document using a data structure having a hierarchy of nodes. The nodes describe respective elements in the ink document. The technology leverages the data structure to identify a set of nodes that grows upon the user's repeated selection of a particular part of the ink document. At each stage of the selection, the technology highlights a set of elements in the ink document that correspond to the current set of identified nodes. According to another illustrative aspect, the technology produces the data structure by modifying an original data structure provided by a text analysis engine. The technology performs this task with the objective of accommodating structured interaction by the user with the ink document.

Abstract: System for customizing visual field (VF) tests uses a machine learning model (15) trained on retina images (12A, 12C, 12D), including optical coherence tomography (OCT), optical coherence tomography angiography (OCTA), fundus, and/or fluorescein angiography images. In operation, in preparation for administering a specific VF test (13) to a patient, a retina image of the patient is submitted to the present machine model, which responds by synthesizing a VF prediction for the patient. The synthesized VF may be used to optimize the specific VF test prior to administering it to the patient.

Abstract: A self-locking latch assembly for a two-piece container is provided. The latch assembly has a latch hook pivotably biased in a parallel orientation to the first piece of the two-piece container, while a keeper is connected though spaced apart from the surface of the second piece of the two-piece container. The two-piece container is adapted to move between an open and closed position by sliding an open end of the larger piece over an open end of a smaller piece. During this sliding action, toward the closed position, a tapered edge of the latch hook strikes the keeper and is urged upward until the tapered edge ends, whereby the biasing of the latch hook urges it to engage the keeper in a locked condition. To unlock the latch hook, one can pivot it to a nonparallel orientation and slide the two pieces apart.

The foregoing tissue products may have a sheet bulk greater than about 8.0 cc/g and a Stiffness Index less than about 15.0. In certain instances the tissue product and webs may be through-air dried and may be either creped or uncreped.
