Abstract: Methods, apparatus, and systems for multi-resolution processing for video classification. A plurality of video frames of a video are obtained and a resolution for classifying each video frame of the plurality of video frames is determined by analyzing each video frame using a policy network. Based on the determined resolution, each video frame having a determined resolution is rescaled and each rescaled video frame is routed to a classifier of a backbone network that corresponds to the determined resolution. Each rescaled video frame is classified using the corresponding classifier of the backbone network to obtain a plurality of classifications and the classifications are averaged to determine an action classification of the video.

Abstract: Techniques regarding star polymers with enhanced antimicrobial functionality are provided. For example, a polymer is provided that can comprise a core that can have a singlet oxygen generator and that can generate a singlet oxygen species upon irradiation with light. The polymer can also comprise a plurality of polycarbonate arms covalently bonded to the core. The plurality of polycarbonate arms can be degradable and can comprise a cation. Further, the plurality of polycarbonate arms can have antimicrobial functionality.

Abstract: An apparatus for holding a door is disclosed. The apparatus includes a body member configured to be coupled to a floor. Further, the apparatus includes a locking member movably coupled to the body member, and having an end that is configured to engage the door. Further still, the apparatus includes a stop arrangement coupled to the locking member and configured to hold the locking member in a predetermined position relative to the body member. The predetermined position associating with a predefined door position, such that the holding prevents the door from moving past a predefined door position when the locking member is engaged with the door.

Abstract: The invention relates to an apparatus for holding a door. The apparatus includes a door mounting plate configured to be mounted on the door. The door mounting plate is arranged to extend perpendicularly from the door and includes a door binding portion. The apparatus further includes a rigid body member arranged to be coupled to a floor and to extend perpendicularly from the floor wherein the body member is substantially immovable by a force exerted by the door. The apparatus additionally includes a locking member coupled to the body member. The locking member is disposed substantially perpendicular to the body member and has a locking member binding end configured to engage with the door binding portion.

Abstract: Methods and apparatus for generating a small, maneuverable stream of filtered fluid without benefit of a pump or electrical power are disclosed. According to one aspect of the present invention, a spray nozzle apparatus for dispensing a maneuverable stream of fluid, that originates from a fluid source at a first pressure includes an adapter assembly, a nozzle subassembly, and a flexible tubing. The adapter assembly is mechanically coupled to the fluid source, and is arranged to allow the fluid to flow from the fluid source through the adapter assembly. The nozzle subassembly dispenses the fluid at a second pressure, and includes a fluid intake end and a fluid dispensing end. The fluid dispensing end allows the fluid to flow therethrough in a small, stream-like configuration at the second pressure, and is in fluid communication with the adapter assembly. The flexible tubing allows the fluid to flow through, and is coupled to the fluid intake end of the nozzle subassembly.

Abstract: The present invention relates, in one embodiment, to an apparatus for holding a door. The apparatus includes a body member and a blocking member rotatably coupled to the body member. The coupling is such that when the body member is positioned vertically in front of the door, the blocking member is disposed in one of a first blocking position and a second blocking position. The blocking member, in the first blocking position, contacts the door to hold the door at a first predefined position. The apparatus, when the blocking member is in the second blocking position, contacts the door to hold the door at a second predefined position. The door is opened further in the second predefined position than in the first predefined position.
