Abstract: Techniques relating to streaming video are disclosed. These techniques include identifying one or more streaming video sessions for one or more users based on a plurality of events relating to streaming video for the one or more users. The techniques further include storing data for the one or more streaming video sessions in an electronic database, based on the plurality of events, identifying a plurality of metadata relating to the events, and determining, based on a threshold value, a time to store at least a portion of the plurality of metadata in the electronic database, the time occurring after the storing the data for the one or more streaming video sessions. The techniques further include responding to a query for metrics relating to the one or more streaming video sessions by aggregating at least a portion of the stored data.

Abstract: A dual tire buffing apparatus includes a turntable having a first end and an opposite second end. The turntable is rotatable about a central axis between first and second positions. A first expandable hub is rotatably coupled to the turntable proximate the first end. The first expandable hub is configured to receive a first tire casing. A second expandable hub is rotatably coupled to the turntable proximate the second end. The second expandable hub is configured to receive a second tire casing. A rasp head is positioned to operatively engage the first tire casing on the first expandable hub when the turntable is in the first position to perform a buffing operation on the first tire casing, and to operatively engage the second tire casing on the second expandable hub when the turntable is in the second position to perform a buffing operation on the second tire casing.

Abstract: Systems and methods of buffing tire casings are provided. A tire buffing machine includes a tire hub assembly selectively rotating a mounted casing, a buffer configured to buff the casing, a tire belt detection apparatus having two or more sensors to detect a first belt depth of one or more belts at a first lateral position in a tire casing and a second belt depth of the one or more belts at a second lateral position within the tire casing, and an electronic controller. The controller determines the first belt depth and the second belt depth using a belt detection apparatus having two or more sensors of the belt detection apparatus and adjusts the operation of the buffer based on the first belt depth or the second belt depth.

Abstract: A vacuum insulated cabinet structure includes panels having sheet metal outer side walls and polymer inner side walls. The polymer inner side walls are heat-sealed to a layer of polymer material laminated to a flat sheet metal blank to form vacuum cavities. The blank is then bent along fold lines to form a cabinet structure.

Abstract: The present invention provides improved devices for removing energy and fluid from body fluid containing spaces and surfaces of a mammal, the devices including isolated air and water delivery systems configured to simultaneously deliver streams of dry air and liquid water to the nostrils of a patient, without allowing the streams to come into contact with one-another until it enters the patient's nostrils.

Abstract: Delivery landing pads for unmanned aerial vehicles (UAVs) are disclosed. A disclosed landing pad to support a UAV includes a landing surface, and a pressure sensor operatively coupled to the landing surface. The landing pad also includes a processor to determine a presence of the UAV on the landing pad and calculate a weight of a payload transported by the UAV based on a measurement of the pressure sensor to determine whether the payload has been delivered to the landing pad.

Abstract: A missile includes a rocket motor that has a flow deflector in an expansion region of the rocket motor's nozzle. The flow deflector diverts flow of combustion products away from a safe region that is aft of the missile. The safe region protects an operator of a launcher used to fire the missile, such as a shoulder-fired launcher, from harm caused by the combustion products. The flow deflector may be small enough such that it does not significantly adversely affect the performance of the rocket motor. The presence of the flow diverter may allow for the rocket motor to be started sooner in the flight of the missile, or at a distance closer to the operator, while still keeping the operator safe. The flow deflector and supporting structure, such as struts, may be additively manufactured with at least an aft part of the nozzle, as a continuous single-piece part.
