Abstract: Ultrasonic audio processing circuitry and a method useful in ultrasonic presence detection. An ultrasonic burst generator produces an ultrasonic burst signal at one or more ultrasonic frequencies, and an equalizer equalizes that ultrasonic burst signal according to frequency response characteristics of the speaker and microphone at those ultrasonic frequencies. Driver circuitry drives a speaker with the ultrasonic burst signal, which may be combined with an audible audio signal. An ultrasonic separation filter separates an ultrasonic portion from a signal received at a microphone, and processing circuitry is provided to determine a delay time of an echo corresponding to the ultrasonic burst signal in that separated ultrasonic portion of the received signal. In another aspect, the equalizer equalizes an ultrasonic portion of the signal received at a microphone, according to frequency response characteristics of the speaker and microphone at the ultrasonic frequencies of the burst.

Abstract: Disclosed is a system for monitoring a boss of a composite structure for a boss cracking event. The system includes a first sensor located on an outer surface of a neck of the boss and configured to detect first deformation data associated with the boss. The system also includes a second sensor located on the outer surface of the neck of the boss at a location diametrically opposite of the first sensor and configured to detect second deformation data associated with the boss. The system also includes a controller communicatively coupled to the first sensor and the second sensor and configured to determine, based on the first deformation data and the second deformation data, whether a boss cracking event has occurred.

Abstract: Disclosed is a sensor for monitoring a composite structure. The sensor includes multiple sensing elements of different sizes, each configured for different respective monitoring tasks. Also disclosed are methods of fabricating the sensor, designing and manufacturing the sensor, and attaching the sensor to the composite structure.

Abstract: Methods, systems, and apparatus for monitoring a cylinder. The system includes a plurality of sensors connected to the cylinder and configured to detect deformation data associated with the cylinder. The system includes a controller communicatively coupled to the plurality of sensors. The controller is configured to determine a damage value based on the detected deformation data when the cylinder endures impact damage. The controller is configured to communicate a notification when the damage value exceeds an impact damage threshold. The system includes a filling controller communicatively coupled to the plurality of sensors. The filling controller is configured to control a valve for filling the cylinder with a fluid. The filling controller is configured to detect damage to the cylinder above a specified threshold as the cylinder is filled with the fluid. The filling controller is configured to automatically perform a safety action when the damage to the cylinder is detected.

Abstract: A pressure vessel assembly incudes a pressure vessel and a gas density gauge. The pressure vessel includes a vessel wall defining an interior cavity. The gas density gauge includes a parallel plate capacitor having a pair of plates. Opposing surfaces of the plates are separated by a distance across an open gap. A capacitance of the capacitor is related to a density of a gas within the open gap.

Abstract: A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.

Abstract: A Monte Carlo simulation engine configured to perform a primary beneficiary test to determine whether a variable interest entity holder is a primary beneficiary of a financial instrument. The engine includes a cash flow engine configured to generate a set of default/prepayment curves representing one or more discrete cash flow scenarios for one or more loans for the financial instrument, the default/prepayment curves representative of systemic risk associated with the financial instrument. The engine further includes an idiosyncratic risk module configured to convert the set of default/prepayment curves defined by the cash flow engine into a number of occurrences, which, at an aggregated level, mimic the default/prepayment curve from a systemic risk model.

Abstract: The present invention discloses a system and a method for providing and managing promotional and informational resources provided by drug manufacturers to HCPs. An HCP assistance system is disclosed having a static information repository with an information component that manipulates information recorded within the static information repository. HCP accessing the present invention are required to authenticate their membership in the system as well as their good standing with a licensing body. This authentication is performed within a presentation component that can be accessed via global computer network (GCN). An information component also provides an HCP with access to available drug samples, and any objective factual information related to a treatment, as well as any resources provided by pharmaceutical manufacturers to assist indigent patients.
