Abstract: Technologies are described for devices and methods to seal a diaphragm to a body exterior seal periphery. The methods may comprise rotating a handwheel of a bonnet assembly to move a load plate to apply a compression force to a top portion of a transition pressure ring. The top portion of the transition pressure ring may have a circular cross section. A bottom portion of the transition pressure ring may include a bead that may project out from a bottom surface of the bottom portion and may have a congruent shape and size as the body exterior seal periphery. The body exterior seal periphery may not be congruent to the circular cross section of the top portion. The compression force may press the bead against a diaphragm assembly and the diaphragm against the body exterior seal periphery, to seal the diaphragm to the body exterior seal periphery.

In an embodiment, the PDCCH may include PDCCH candidates from search space sets, associated with control resource sets (coresets), that are configured for repetition. The wireless device may also receive a transport block via the PDSCH, where the resource block (RB) numbering of the PDSCH starts from a lowest RB of a coreset with the lowest index among the coresets.

Abstract: A headset includes a tissue transducer on a carriage that translates along a temple portion of the headset. The carriage is configured to contact the helix root of a user's ear. The helix root provides a reference point, and when the carriage is contact with the helix root, the tissue transducer is configured to be located in a target area. By maintaining a fixed location of the tissue transducer relative to the helix root of the user's ear, the tissue transducer may be accurately positioned, even for users with different head shapes and sizes.

Abstract: A method to prepare cannabinol (CBN) from derived cannabidiol (CBD) is disclosed. The CBD can be derived from hemp and reacted with a halogen, leading to the cyclization and aromatization of CBD to CBN. The removal of halogen is improved via selective solvent exchange. CBN is isolated from the reaction mixture by use of orthogonal chromatography techniques to provide CBN of high purity.

The universal joint also includes one or more independent contact objects disposed between a contact surface of the first joint member and a contact surface of the second joint member. The universal joint also includes a load rod disposed in an axial channel between the first joint member and the second joint member.

Abstract: A switchable privacy display comprises a spatial light modulator (SLM), a first switchable liquid crystal (LC) retarder and first passive retarder between a first pair of polarisers and a second switchable LC retarder and second passive retarder between a second pair of polarisers. The first switchable LC retarder comprises two homeotropic alignment layers and the second switchable LC retarder comprises two homogeneous alignment layers. In privacy mode, on-axis light from the SLM is directed without loss, whereas off-axis light has reduced luminance to reduce visibility to off-axis snoopers. The display may achieve privacy operation in landscape and portrait orientations. Further, display reflectivity may be reduced for on-axis reflections of ambient light, while reflectivity may be increased for off-axis light to achieve increased visual security. In public mode, the LC retardance is adjusted so that off-axis luminance and reflectivity are unmodified.

Abstract: A compact action for a firearm including an upper receiver housing incorporating a barrel. A bolt and supporting carrier is positioned within the receiver housing so that the bolt is engaged to a rear receiver end of the barrel in a cartridge chambering position. Guide rods are supported within the housing above the barrel and extend in parallel to a rear located end plate. The carrier includes a carrier key supported by and displaceable along the guide rods between the barrel and a rearward bumper component. A gas tube extends from a forward located gas block overlaying a gas discharge aperture in the barrel to a gas key for actuating the carrier rearwardly following discharge of a ballistic from the barrel. A charging handle is manually displaceable along a slot in the housing for actuating an interior slider component, in turn actuating the carrier key to cycle the carrier and bolt.

Abstract: Aspects of the present disclosure relate to systems and methods for using content as navigation in an application. In one aspect, rendering of a first column including one or more content previews in a user interface to an application is initiated. Rendering of a second column including detail content corresponding to at least one of the one or more content previews in the user interface to the application is initiated. The one or more content previews and the detail content may be scrolled across the user interface when a moving input corresponding to a portion of the one or more content previews or a portion of the detail content is detected.

Abstract: A wide band gap semiconductor NAND based neutron detection system includes a semiconductor layer comprising a wide band gap material with a neutron absorber material in the wide band gap material, and the semiconductor layer is the only layer of the wide band gap semiconductor NAND based neutron detection system fabricated with the neutron absorber material.

Abstract: An example system disclosed herein includes an analyzer to determine a first priming characteristic of media at a first location based on first neuro-response data and determine a second priming characteristic of the media at the second location based on second neuro-response data. The example system includes a selector to select a third location in the media after the first location or a fourth location in the media after the second location as a candidate location for introduction of advertising material based on the first priming characteristic and the second priming characteristic. The selector is to select the third location when the first priming characteristic indicates increased receptivity to the advertising material at the first location relative to the second priming characteristic and select the fourth location when the second priming characteristic indicates increased receptivity to the advertising material at the second location relative to the first priming characteristic.

Abstract: A system for managing opening and closing a pocket door includes a spindle, an actuator, and brackets. The spindle extends along a longitudinal axis between first and second ends, and is configured to be coupled to the pocket door. The actuator is coupled to the spindle and is configured to cause the spindle to move axially along the longitudinal axis. The brackets are connected to the spindle at each end and are constrained from longitudinal motion relative to the spindle. The brackets are configured to affix the spindle to the pocket door. A bushing system couples each bracket to the spindle and is configured to dampen impact between the spindle and the brackets. For example, the bushing system may include lobed elements, made of a rubber material, that engage each other to transmit azimuthal forces. In some embodiments, another actuator is included to improve cycle life and redundancy.

Abstract: A wearable wireless device may be configured for control of a parameter of a load control device. The load control device may be responsive to a network device, for example, to provide fine tune adjustment of the parameter. The wearable wireless device may include a touch-responsive visual display for displaying feedback of the parameter of the load control device. The visual display may be configured to be actuated to receive a user input to adjust the parameter of the load control device. An actuation of the visual display of the wearable wireless device may adjust the parameter by a greater percentage than the fine tune adjustment provided by the network device.

Abstract: Described is a system for intelligent re-tiering of backup data stored on a cloud-based object storage. More specifically, the system may re-tier objects such that the system retains the ability to efficiently perform a full restore of backup data even when incremental backups are performed to a cloud-based object storage. To provide such a capability, the system may maintain a specialized metadata database that stores information indicating the backup time for each backup, and a list of objects required to perform a full restore to each of the backup times. Accordingly, when using a threshold time (e.g. expiry) to select object candidates for re-tiering, the system may leverage the metadata database to ensure that objects that may still need to be referenced are not unnecessarily moved to a lower storage tier.
