Abstract: A can cutting device that has a main body and a can support assembly coupled to the main body. The can support assembly has a shaft that extends along a longitudinal shaft axis, an eccentrically mounted mandrel that extends along a longitudinal mandrel axis parallel to the longitudinal shaft axis, and a cutter coupled to the main body having a cutting surface. The can is positionable in a mounted position such that the can is rotatable about a can axis of rotation, the cutting surface is positional to contact the portion of the can body supported by the mandrel at the cutting location, and when the cutting surface is in contact with the portion of the can body supported by the mandrel at the cutting location and the can is rotated about the can axis of rotation, the cutter cuts the portion of the can body at the cutting location.

Abstract: Various embodiments are described herein for systems and methods that can be used to operate a media transmission network. In at least one embodiment, the media transmission network comprises a plurality of media processing devices configured to receive and process media streams based on control data. The media transmission network also comprises a controller coupled to the plurality of media processing devices and configured to generate a control signal for some or all of the media processing devices in the network. The controller is configured to determine the timing at which to transmit the control signal to a respective media processing device in order for the instructions in the control signal to be executed at the same time as the media data is received. The controller determines the transmission timing of each control signal by determining the latencies and delays of the network and the devices, such as, for example, network latency, processing delay, and/or control delay.

Abstract: A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.

Abstract: Provided herein are methods for enhancing infection, growth, spread, or titer of an oncolytic RNA virus in a cancer or tumor cell; enhancing the oncolytic activity, cytokine-induced cell death activity, and/or cytotoxic activity of an oncolytic RNA virus in a cancer or tumor cell; upregulating cytokine response to, and/or enhancing the immunotherapeutic activity of an oncolytic RNA virus in a cancer or tumor cell; and/or treating a tumor or cancer in a subject in need thereof. Such methods employ a vanadium-containing compound, administered to the cancer or tumor cells before, after, or concurrently with infection of the cancer or tumor cells with the oncolytic RNA virus. Related compositions, uses, and kits therefor are also provided. Methods for producing RNA viruses, RNA virus-based cancer vaccines, and RNA virus-based cancer gene therapy vectors are also provided.

Abstract: A reluctance motor has salient teeth on both the stator and the rotor. The reluctance motor includes electrical coils that are usable to generate magnetic flux to drive rotation of the rotor. Concentrated coil windings are wound around each stator tooth. The electrical coils are arranged across all the stator teeth of the reluctance motor to enable the reluctance motor to be driven by alternating current. The electrical coils are arranged so that, when excited with alternating current, the number of magnetic half-poles is equal to the number of teeth on the rotor. The reluctance machine can operate using an inverter instead of an asymmetric bridge.

Abstract: A system and method for estimating steam quality for a steam generator is provided which involves obtaining raw measurement values for process variables of the steam generator from sensors coupled to the steam generator; receiving the raw measurement values and slow-rate steam quality samples in order to determine a steam quality estimate, using a measurement module to receive the raw measurement values and determine model input values and a robustness index; using an estimator module to determines a raw steam quality estimate using the model input values and a model that is selected from several models depending on reliability of some of the raw measurements; and using a corrector module to determine the steam quality estimate using the raw steam quality estimate, robustness index, and slow-rate steam quality samples. An output receives the steam quality estimate and can provide the steam quality estimate to another device.

Abstract: A hand vacuum includes a nozzle portion at a front end of the hand vacuum having a dirty air inlet. An air flow passage extends from the dirty air inlet to a clean air outlet in a main body rearward of the nozzle portion. The main body houses a suction motor in the air flow passage. First and second laterally spaced apart opposed arm members extend generally axially between the nozzle portion and the main body, and a volume is positioned between the nozzle portion, the main body and the opposed arm members. An air treatment member assembly comprising an air treatment member is removably downwardly from a position within the volume.
