Abstract: Technology for asynchronous communication including a wired channel, a sender controller, and a receiver controller is disclosed. The sender controller can be configured to send multiple request signals up to a predefined limit on the output request port paired with multiple data blocks sent on the data before receiving an acknowledgment signal on the output acknowledge port. At least one combination of any of the input channel, the sender controller, the output channel, and the receiver controller can be configured to operate within at least one time constraint to avoid stalling an asynchronous flow control.

Abstract: A compact electronic timpani configured to provide substantially the same or better performance characteristics as a conventional full-size acoustic timpani while being substantially smaller in size. A compact electronic timpani consistent with the present disclosure provides a musician with a similar playing experience as that of conventional full-size acoustic timpani or set of timpani. The compact electronic timpani may allow a performer to perform conventional timpani playing techniques and experience substantially the same acoustical properties, physical sensations and tone production as the performer would encounter when playing a full-size acoustic timpani without the limitations commonly associated with size and/or cost of a full-size acoustic timpani.

Abstract: A system and method for measuring a frequency of a wire in a vibrating wire gauge. The system may include a signal generator for generating a signal at a frequency that matches a frequency of the wire vibration and an excitation unit for exciting the wire to increase an amplitude of the wire vibration. The excitation unit may excite the wire using the signal. The system may further include a signal gate for controlling when the signal is sent to the excitation unit.

Abstract: A well cement composition for plugging a bore at the location for initiating sidetracking to bore a lateral well is formulated as a slurry of hydraulic cement that contains at least two, but preferably all three of the following additives: (1) a source of silicon dioxide, (2) fracturing proppants and (3) an expansion compound selected from the group consisting of 1%-5% crystalline silica and 60%-99% MgO or CaO, and their mixtures.

Abstract: System and method for inducing rapid reentry of orbital debris including determining a spatial extent of the orbital debris, and deploying dust to the orbital debris to enhance the drag on the orbital debris.

Abstract: Circularly polarized resonant structures are obtained utilizing piezoelectric resonators made of materials and orientations selected in accordance with the teaching provided herewith. Further provided are radially polarized structures. Furthermore, the utilization of such resonators and structures as sensors, for frequency control application, for signal filtering, and the like, is also disclosed.

Abstract: A system and method of modeling a circulatory system including a regulatory mechanism parameter. In one embodiment, a regulatory mechanism parameter in a lumped parameter model is represented as a logistic function. In another embodiment, the circulatory system model includes a compliant vessel, the model having a parameter representing a change in pressure due to contraction of smooth muscles of a wall of the vessel.

Abstract: A method for removing and/or replacing tubes for generating ions in air flowing through an enclosed or partially enclosed structure. The method enables the tube to be removed and replaced without having to remove the device mounted to the structure that retains the tube.

Abstract: An assembly for use in a fully or partially-enclosed structures (such as an HVAC duct) includes a housing, a tube mounting member and a tube for generating ions. The housing has a cavity that can be accessed by removing a cover, and the tube may be removed from the tube mounting member without unscrewing or removing any components attached to the structure.
