Abstract: Disclosed herein are representative embodiments of generating representative motion information that can be used during processing of a video frame. In one exemplary embodiment disclosed herein, a reference frame comprising a group of blocks is processed, and motion information for the group of blocks is compressed at least by buffering representative motion-vector information and representative reference-frame index information for the group of blocks. The representative reference-frame index information comprises reference-frame index information of a representative block of the group of blocks, and the representative reference-frame index information represents reference-frame index information for the group of blocks during processing of a current frame.

Abstract: A sports helmet kit has a shell, attachable face guard, composite helmet liner, and fit pods to improve and customize the fit of the helmet to the wearer. The composite liner consists of a base liner and a selected group of fit elements, for example, fit pods, removably attached to the inner surface of the base liner (i.e., the surface of the base liner facing the wearer's head). The fit pods are selected from a set of fit pods having different properties, for example, different sizes, thicknesses, densities, and cross-sections. The selection of fit pods from the set may be aided by taking anatomical measurements of the wearer's head and analyzing the measurements with respect to the geometry of the helmet to produce a pressure map. The measurements may be taken by physical contact or by non-contact means. The fit pods may be selected to optimize a pressure map, and thus optimize the fit, for a given wearer of the helmet.

Abstract: More effective authentication protocols for provisioning electronic devices are provided. An approval signal responsive to a provisioning request may be transmitted in real-time, such as under four seconds in certain embodiments. An authentication score for the provisioning request may be calculated even after transmitting the approval signal. In certain embodiments, information gathered from the successful provisioning of a device can be used in the authentication scoring process. Authentication scores deemed to fall below a requisite threshold may be used to suspend the provisioned device, therefore, limit the ability for the device to utilize the account, however, without withdrawing the approval or granted digital token. Certain implementations may negate the need to transmit further approvals or confirmations following determining an authentication score met a threshold.

Abstract: A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

The hook is configured to attach to a cylindrical connector on the door. The base portion is configured to attach to the interior surface such that when connected the hook is at least partially hidden when viewed from an exterior of the litter container.

Abstract: An overfill-prevention valve system includes a testing mechanism, operable by a user from the inlet end of the drop tube, which can be used to verify proper valve function without actually filling the storage tank. The testing mechanism allows the user to actuate the valve manually using a test probe, such as by elevating a float to simulate a full storage tank. The testing mechanism may be located upstream of the valve to facilitate the testing operation without interfering with the valve body. The mechanism may further provide non-contact functionality, such as with magnetic actuators on either side of the drop tube wall, to eliminate a potential test mechanism leak points. The test probe used to actuate the test mechanism may be shaped to define a desired rotational position at the test location within the drop tube, ensuring proper rotational alignment of the magnetic actuators.

Abstract: Ultrasonic horns having improved longevity and simplified manufacturing approaches that can be more easily adapted to ultrasonic reactor chambers or batch processing containers. The ultrasonic horn designs increase the uniformity and intensity of acoustic energy radiated into a liquid medium and thus better correspond to the requirements of a particular sonochemical or sonomechanical process. The ultrasonic horns do not require a specific number of cylindrical sections and allow for various lengths and profiles of variable-diameter sections. The ultrasonic horns also reduce stress in the material of the ultrasonic horns and therefore extend longevity.

The manifold of the present disclosure provides channels that can be easily cleaned and allow for an increased flow performance.

Abstract: A status indicator for a capacitor may include first and second indicator plates, each respectively defining a first face and a second face visually distinct from the first face. The first face of each of the first and second indicator plates is displayed during nominal operation of the capacitor. The second face of only one of the first and second indicator plates is displayed in response to a partial failure of the capacitor. The second face of each of the first and second indicator plates is displayed in response to a complete failure of the capacitor. A system may include a capacitor, and the status indicator coupled to the capacitor. A method for visually indicating a status of a capacitor may include controlling, by a controller, first and second indicator plates to display selected faces indicating nominal operation, partial failure, or complete failure of the capacitor.

Abstract: A technique for tracking, for example, the temperature of one or more sample vials containing biological material stored in a low-temperature shipping vessel. Each sample vial has vial electronics that senses temperature and transmits temperature data to the reader head of a reader device, which has a controller that is not at the low temperature. In some implementations, the shipping vessel has a cap with a recess that houses the controller and a hollow plug that houses a cable that connects the controller to the reader head that is located in the vessel's cold interior sufficiently close to the sample vial to enable interaction with the vial electronics. In some implementations, the reader head transmits electrical power to the vial electronics. By tracking the temperature of individual sample vials rather than the temperature of the vessel interior, more-relevant temperature data is available.
