Abstract: A shredding assembly for tearing a plastic article, such as waste bottles into pieces or pellets. The shredding assembly includes rails that can be installed at a height and a shredder. The shredder includes a housing mounted on the rails and can slide from a stowed position to over one or more trash bins. The shredder includes two rollers mounted within the housing and a drive mechanism for counter-rotating the two rollers.

Abstract: Aspects of the subject disclosure may include, for example, a device that performs operations including receiving a request for a communication session, determining participants of the communication session, determining a location of each participant of the communication session, selecting a virtual media server from among a group of media servers according to a location that reduces a communication path among the participants for the communication session, instantiating the virtual media server at a start time of the communication session, grouping the participants of the communication session into end points, and relaying communication session data between the end points. Other embodiments are disclosed.

Abstract: A virtual reality system is described herein. The virtual reality system includes a cane controller and a computing system. The cane controller comprises a rod, a sensor, and a brake mechanism, wherein the sensor is configured to generate a signal that is indicative of position, direction of movement, and velocity of the rod, and wherein the brake mechanism is configured to apply a force to the rod. The computing system receives the signal, computes a position, direction of movement, and velocity of a virtual rod in a virtual space, and outputs a control signal to the brake mechanism based upon such computation. The brake mechanism applies the force to the rod in a direction and with a magnitude indicated in the control signal, thereby preventing the user from causing the virtual rod to penetrate a virtual barrier in the virtual space.

Abstract: Provided herein are compounds that exhibit activity as fungicides and are useful, for example, in methods for the control of fungal pathogens in plants and can be applied to said plants in a variety of ways.

Abstract: A powder delivery system for use in an additive manufacturing device includes a powder control valve configured to selectively divert at least a portion of an input fluid flow to a return line while a remainder of the input flow is delivered to a delivery nozzle. In some embodiments, the powder delivery valve may be modulated to alter the percentage of input flow diverted to the return line. Alternatively, the powder delivery valve may be either fully open or closed. In each embodiment, the powder delivery valve permits rapid changes in the amount of powder delivered to the nozzle.

Abstract: A disposable container for biologic materials comprising a sheet of flexible material with an access area integrally molded in the sheet. At least one port in the access area passes fluid into the container. The sheet is folded along the access area such that an upper part is adjacent a lower part, and the upper part is attached to the lower part. The method for making the container includes forming a sheet having an access area integrally molded in the sheet, folding the sheet along the access area, and joining the upper part to the lower part. The upper and lower sheets and the access area are injection-molded as a single, unitary piece. This process uses a mold having a central triangular prism and conforming upper and lower blocks.

Abstract: A method and apparatus for using a passive telephone monitor to control collaborative systems comprising one or more local computers connected to one or more remote computers, wherein an image displayed on the local computer is substantially simultaneously displayed on the remote computer.
