Abstract: A paint tray carrying device includes a box which has a front end that is open and an entrance extending through a top wall of the box which intersects the front end. In this way a paint tray can be inserted into the box having the paint tray in a horizontal orientation thereby inhibiting paint from spilling from the paint tray. Thus, the box and the paint tray inhibit the paint from being spilled on a crucially sensitive surface which is located near a painting work location. A gripping element is integrated into the top wall which can be gripped by a user for carrying the box and the paint tray. The gripping element is aligned with a center of gravity of the box to facilitate the box and the paint tray to be balanced on a horizontal plane when the user is carrying the box.

Abstract: This disclosure is directed to methods and systems for cryptographic asset generation using short range wireless communication. The methods and systems enable creation and distribution of cryptographic assets with proof of in-person contact over various wireless technologies, including but not limited to, NFC, low-energy Bluetooth, and others. This is achieved by passing a cryptographic asset template from a creator device to a collector device via NFC. The cryptographic asset template is passed to a server for confirmation and subsequently starts the process of minting a smart contract on a blockchain. The processes disclosed herein include cryptographic asset template creation, template distribution, template-to-cryptographic asset creation, and smart contract execution.

Abstract: A heat exchanger includes a sensor grid with sensor leads extending through tube restraints for heat exchange tubes in the heat exchanger. The tube restraint includes a body having a plurality of tube openings defined therein with each tube opening receiving one heat exchange tube of the set of heat exchange tubes therethrough. The body also includes a sensor lead opening defined therein to receive a sensor lead therethrough. Each tube opening has a larger dimension than the sensor lead opening. The sensor grid is installed during manufacture rather than in the field, allowing the sensor grid to be on outermost and inner sets of heat exchange tubes in the heat exchanger.

Abstract: Drones are engineered with sensors for use in insurance applications. After locating an object of interest, a drone performs an investigation by probing the object of interest. Sensors receive feedback from the object of interest. An electronic fingerprint of the drone is produced. Afterward, perils are computed based on the feedback and the fingerprint of the drone is used in insuring the object of interest. The act of probing includes thumping, drumming, or radiating ultrasound waves against the object of interest. The sensors can be turned off when they are within a geographic zone of prohibited operations.

Abstract: Styrene-free unsaturated polyester resin and vinyl ester resin compositions are provided which contain low amounts of hazardous air pollutants, good mechanical and physical properties, and good corrosion resistant characteristics. The resin systems are such that minimal or no component is leachable after completion of the curing process. The resins are suitable for repair of sewer pipes and potable water pipe systems as part of a cured-in-place pipe application. Additionally, the invention is suitable for relining of storage tanks. A process for the manufacture of these resin compositions is also provided.

Abstract: Determining a bit rate at which to deliver a packet stream over a network link. An origin device transmits over the network link unsolicited data packets to a destination device while contemporaneously transmitting over the network link a first packet stream encoded at an initial bit rate to the destination device. The origin device may be, but need not be, a content delivery network (CDN) edge node and the destination device may be, but need not be, a cable modem (CM). The origin device determines whether the network link supports delivering a second packet stream in lieu of the first packet stream encoded at a higher bit rate based, at least in part, on an amount of retransmission requests the origin device receives for packets in the first packet stream from the destination device.

Abstract: A device is described herein comprising a base unit including at least three transceivers, wherein the at least three transceivers are communicatively coupled with at least one processor of the base unit. The at least one processor and the at least three transceivers are configured to determine locations of a transceiver remote to the base unit, wherein the location determinations comprise a series of transceiver locations along a boundary path, wherein the series of location determinations define a boundary region. The at least one processor determines locations using information of communications between the transceiver and the at least three transceivers and the relative positioning of the at least three transceivers.

Abstract: A method for additively manufacturing a component includes receiving, via an additive manufacturing system, a geometry of the component and melting and fusing, via an energy beam of the additive manufacturing system, material layer by layer atop a build platform according to the geometry so as to build up a plurality of layers that form the component. The method also includes determining a surface area change from one of the plurality of layers to the next based on the geometry. Further, the method includes temporarily discontinuing melting and fusing of the material by the energy beam between building of one or more of the plurality of layers so as to provide a delay after building one or more of the plurality of layers when the surface area change is above a predetermined threshold. As such, the delay allows for one or more previously built layers to at least partially cool so as to eliminate and/or reduce build failures from occurring in the final component.
