Abstract: A fire suppression nozzle can include a first fluid channel configured to be in fluid communication with a first fluid having a first flow velocity and a second fluid channel configured to be in fluid communication with a second fluid having a second flow velocity. A mixer can be disposed between the first fluid channel and the second fluid channel such that the mixer is configured to induce streamwise vorticity in at least the first fluid exiting first fluid channel to cause mixing of the first fluid and the second fluid to reduce a flow speed of a mixture of the first fluid and the second fluid.

Abstract: A handheld computer device is configured to selectively receive a plurality of fluid output values from a paint sprayer and configured to operate in an accessible mode in which the handheld computer device is in a first location where wireless connectivity, via a continuous or near continuous communication path, to at least one of a network server or the paint sprayer is accessible or operate in an inaccessible mode in which the handheld computer device is in a second location out of range of the continuous or near continuous communication path to at least one of the network server or the paint sprayer.

Abstract: Methods and systems for treating a spinal joint with a facet joint replacement. The prosthesis can include a first component having a first articulating surface and a second component having a second articulating surface. The first component is attached to a superior articulating facet and the second component is attached to an inferior articulating facet. The first articulating surface and the second articulating surface articulate with each other and allow for multiple degrees of movement of the facet joint without fusing the joint.

Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

Abstract: An automatic bond redemption apparatus is provided that facilitates the processing and/or redemption of one or more U.S. Savings Bonds with little or no involvement from employees of a financial institution providing the service. Image data acquired from the savings bond is processed in order to determine bond information related to the nature of the bond, the bond information may be used to index one or more valuation databases in order to determine the value of the savings bond.

Abstract: By this invention, The Magnetic Field Power Converter, which we call “Magi”, is disclosed which extracts the potential energy inherent in the atomic structure of it's magnet(s) and transforms it into generated electricity and the kinetic energy and torque of a rotating, integral driveshaft. The “Magi” consists of a unique arrangement of permanent magnet(s) and air-solenoid/electromagnet(s), coupled with a standard automotive battery and unique design “Pulser” electro-mechanical device we have developed. Brief, timed, pulses of direct current, from the battery to the coils of the air-solenoid/electromagnet, thru the “Pulser”, energize the coils. The resulting electromagnetic field repells the permanent magnet causing it and the integral driveshaft it is mounted on to rotate and alternating current to be generated in the coils.

Abstract: This invention discloses a hardware manager and scheduler device which can be implemented within a distributed operating system. The scheduler replaces software synchronization and interaction with two unit-level hardware units that facilitate task scheduling. These units utilize global machine memory to manage scheduling queues using a simple algorithm. The "tasks" managed may be programs requiring execution by a processor, other shared system resources that must be cooperatively scheduled, or input/output queues through system peripheral connections. One unit manages tasks waiting to be executed while the other unit manages tasks which have been completed. Each unit reads and writes pointers to task control blocks stored in a shared memory into and from one or more circular memory queues stored separately in the shared memory. Each queue may correspond to a particular task priority and may be separately managed by the device of this invention.
