Abstract: A method, non-transitory computer readable medium, and computing device that determines when a software failure associated with a virtual storage controller has occurred. At least a portion of a transaction log corresponding to the virtual storage controller is stored in a stable storage device, when the determining indicates that the software failure associated with the virtual storage controller has occurred. A determination is made when the virtual storage controller has rebooted. The at least a portion of the transaction log is retrieved from the stable storage device, when the determining indicates that the virtual storage controller has rebooted. Thereby, state can be preserved and transactions pending, but not yet committed to storage server devices, can be replayed and proceed with minimal or no impact on the client devices originating the transactions.

Abstract: Devices for separating a host fluid from a second fluid or particulate are disclosed. The devices include an acoustic chamber, a fluid outlet at a top end of the acoustic chamber, a concentrate outlet at a bottom end of the acoustic chamber, and an inlet on a first side end of the acoustic chamber. An ultrasonic transducer and reflector create a multi-dimensional acoustic standing wave in the acoustic chamber that traps and separates particulates (e.g. cells) from a host fluid. The host fluid is collected via the fluid outlet, and the particulates are collected via the concentrate outlet. The device is a large-scale device that is able to process liters/hour, and has a large interior volume.

Abstract: An apparatus is provided for implementation of back-end system for providing point-of-use toolkits. The apparatus may receive an assignment of work tasks assigned to a technician for manufacture of a tangible product. In response, the apparatus may compile a point-of-use toolkit including comprehensive information regarding the work tasks, and transmit the point-of-use toolkit to a front-end system associated with the technician. The apparatus may determine an occurrence of a delay associated with the schedule that impacts the assignment of the one or more work tasks, and transmit information associated with the delay to the manufacturing scheduling system. In response to receiving an update to the assignment of the tasks from the manufacturing scheduling system, the apparatus may compile an update of the point-of-use toolkit, and transmit the update of the point-of-use toolkit to the front-end system.

Abstract: A method, non-transitory computer readable medium, and host device that receives one or more transactions. A state is stored in a transaction log in a volatile memory wherein the state includes information associated with the one or more transactions. The transaction log is stored in a stable storage device when a failure is determined to a have occurred. The transaction log can then be retrieved and replayed subsequent to a reboot. Thereby, state can be preserved and transactions pending, but not yet committed to storage server devices, can be replayed and proceed with minimal or no impact on the client devices originating the write transactions.

Abstract: Quick-release control systems for architectural opening coverings and associated control systems and methods for rapidly deploying the coverings to extended positions. In one embodiment coupling assemblies are provided for controllably coupling and decoupling portions of lifting mechanisms in a variety of covering systems, including roller and cellular shade systems. In yet other embodiments, control systems for controlling a plurality of coverings are provided, which may be configured to remotely and simultaneously deploying each of the plurality of coverings to an extended position in response to a trigger signal.

Abstract: Acoustophoretic devices for separating particles from a non-flowing host fluid are disclosed. The devices include a substantially acoustically transparent container and a separation unit, with the container being placed within the separation unit. An ultrasonic transducer in the separation unit creates a planar or multi-dimensional acoustic standing wave within the container, trapping particles disposed within the non-flowing fluid and causing them to coalesce or agglomerate, then separate due to buoyancy or gravity forces.

Abstract: An acoustophoresis device which includes a substantially vertical flow path of the fluid mixture in order to improve separation of particles/secondary fluid from a primary fluid is disclosed. The vertical flow path reduces velocity non-uniformities in the acoustic chamber resulting from gravity forces. The device includes an acoustic chamber in which multidimensional acoustic standing waves are generated. The fluid can be introduced into the acoustic chamber using a dump diffuser in which a plurality of inlets enter near the bottom of the acoustic chamber such that flow symmetry reduces both, gravity driven flow non-uniformities, and any flow interference effects between inlet mixture flow into the acoustic chamber and the continuous gravity driven particle cluster drop out.

Abstract: An apparatus includes a flow chamber having at least one inlet and at least one outlet. At least one ultrasonic transducer is located on a wall of the flow chamber, which operates to create a multi-dimensional acoustic standing wave in the flow chamber. A reflector is located on the wall on the opposite side of the flow chamber from the at least one ultrasonic transducer. The reflector is formed from a thin structure that provides a pressure release boundary, such as a plastic film/air interface.

Abstract: An acoustophoresis device includes an acoustic chamber with a piezoelectric element located within its volume. The piezoelectric element vibrates and generates acoustic standing waves from both sides, so that particles can be separated from fluid passing through the acoustic chamber. This permits the element to be cooled more efficiently, reducing transient heat loads in the fluid traveling through the device.

Abstract: A single sheet has multiple separation lines arranged such that the sheet can be printed on by a standard printer such as a personal computer printer, and the sheet may thereafter be separated and/or folded in any one of three different configurations to form different possible compact disc jewel case inserts including both face labels and spine labels. One embodiment is of a sheet having at least four longitudinal lines of weakness extending across at least a major portion of the length of the sheet, and at least three latitudinal lines of weakness extending across a major portion of the width of the sheet, with at least one longitudinal line of weakness being a fold about which at least one portion is folded.

Abstract: The present invention is a synthetic speech encoding device that produces a synthetic speech signal which closely matches an actual speech signal. The actual speech signal is digitized, and excitation pulses are selected by minimizing the error between the actual and synthetic speech signals. The preferred pattern of excitation pulses needed to produce the synthetic speech signal is obtained by using an excitation pattern containing a multiplicity of weighted pulses at timed positions. The selection of the location and amplitude of each excitation pulse is obtained by minimizing an error criterion between the synthetic speech signal and the actual speech signal. The error criterion function incorporates a perceptual weighting filter which shapes the error spectrum.
