Abstract: The present disclosure relates generally to ceiling grids, for example, suitable for forming a suspended ceiling. The present disclosure relates more particularly to a support bar configured to extend across grid beams of a ceiling grid. The support bar includes a first hook configured to secure to a first grid beam of the ceiling grid and a second hook configured to secure to a second grid beam of the ceiling grid. A spanning member extends from the first hook to the second hook and is configured to support the weight of an element attached to the support bar.

Abstract: An air-breathing rocket engine in certain embodiments comprises an outer shell and an interior portion situated entirely within the front end of the outer shell. The interior portion includes a funnel-shaped intake and an annular primary combustion chamber between the inner front wall of the shell and the outer surface of the funnel-shaped intake. The intake has a central aperture that is in fluid communication with the throat and exhaust areas within the outer shell. A second circumferential gap is formed between the outer surface of the front inner wall and the inner surface of the front end of the outer shell and is in fluid communication with the throat and exhaust areas within the outer shell. One or more injector ports and one or more ignition ports are situated at the front end of the second circumferential gap.

Abstract: Methods and systems are described for robot transportation of objects into or out of a home automation system. One example may include determining, by a mobile robotic device, that an object is available to cross a boundary of the home automation system. The method may include deactivating at least a portion of the home automation system. The method also include retrieving, by the mobile robotic device, the object and transporting, by the mobile robotic device, the object across the boundary. The method further includes leaving, by the mobile robotic device, the object at a drop-off location. The method may also include reactivating at least the portion of the home automation system.

Abstract: A system for respiratory training including a housing, a respiratory air channel disposed within the housing, a sensor configured to detect a breathing indicator and transmit a breathing indicator signal, a haptic device disposed within the housing, a processor operatively coupled to the sensor and the haptic device, and a memory device operatively coupled to the processor. The memory device includes instructions that, when executed by the processor, cause the processor to receive the breathing indicator signal from the sensor; generate a breath determination based on the breathing indicator signal; and responsive to the breath determination, cause the haptic device to generate a vibration.

Abstract: Embodiments of the present invention relate to proactive computer simulation of portable product failures, and more specifically, to determining the likely cause of an outbreak of foodborne disease or other geographically distributed symptoms of a failure or contamination of a portable product. In one embodiment, a method of and computer program product for simulating portable product failures is provided. Data regarding the locations of consumers of a portable product within a geographic region is received from a data store. A probability density map is determined from the data, indicating where the portable product is likely to be consumed within the geographical region. For each of a plurality of simulated failures of the portable product, the locations of a plurality of simulated incidents arising from the simulated failure are determined.
