Abstract: Acoustic sensing systems having improved vibration cancelation, and methods of achieving improved vibration cancelation. In one example, an acoustic sensing system includes an acoustic sensor configured to produce a sensor output signal representative of a response of the acoustic sensor to acoustic excitation and vibration excitation, at least one accelerometer configured to provide an acceleration signal responsive to the vibration excitation, and a controller, including an adaptive digital filter, coupled to the acoustic sensor and to the at least one accelerometer, and configured to receive the acceleration signal and to adjust coefficients of the adaptive digital filter so as to minimize coherence between a residual signal and the acceleration signal, the residual signal being a difference between the sensor output signal and a filter output signal from the adaptive digital filter.

Abstract: The present invention relates to an in-browser editor. Specifically, embodiments of the present invention provide a system and method of editing content in a browser without having to rely on the particular in-browser editing technology, such as “contentEditable” and “innerHTML.” The system includes a parser that converts an input string representing content edits in the browser into a data structure known as an Intermediary DOM (document object model). The Intermediary DOM provides a completely accurate representation of editor content in real time and operates in tandem with the Browser DOM to render the edited content in the Intermediary DOM back into displayable content.

Abstract: Embodiments relate to a cash card and associated systems and processes. An account structure is provided that allows a non-bank entity to indirectly provide direct deposit capabilities for funds representing pre-payments for negotiable instruments. When a direct deposit of funds into a first account associated with the individual and maintained by a first entity is detected, the total amount of the funds is transferred into a second account associated with the individual and maintained by a second entity. The first entity is a bank or other financial institution subject to federal banking regulations, while the second entity is not subject to federal banking regulations. The individual may withdraw the funds from the second account by requesting the issuance of negotiable instruments. Negotiable instruments may be issued in any dollar amount not exceeding the balance of the second account. A properly enrolled customer may make subsequent deposits into the second account.

Abstract: The systems and methods described herein include an acoustic sensor having piezoelectric material housed in a cartridge and sealed with a solid nonporous stainless steel cover. The systems include additional elements to tune the performance of the acoustic sensor for measuring shockwaves on the surface of an aircraft, such as a helicopter. In particular, the system includes several vibration isolating elements including foam pads and O-rings disposed between the cartridge and the cover for isolating the piezoelectric material from aircraft vibration and turbulence. Additionally, the systems and methods include circuitry for converting analog electrical signals generated by the piezoelectric material, in response to acoustic signals, to digital electrical signals.

Abstract: Anonymous transactions regarding prepaid negotiable instruments may be conducted. An anonymous account may be provided that is identified by an account number. Upon verification of a PIN and the account number, an individual is authorized to make an initial deposit of funds into the anonymous account, representing a pre-payment for negotiable instruments. The individual is thus authorized to request the issuance of negotiable instruments in an amount not exceeding the initial deposit of funds. When the issuance of negotiable instruments has depleted the initial deposit of funds, the anonymous account is closed. However, the anonymous account may be converted into a non-anonymous account, capable of accepting subsequent deposits, if the individual provides personal identifying information.

Abstract: The systems and methods described herein relate to an airborne shooter detection system having a plurality of sensors coupled to the body of an aircraft such as a helicopter. The sensors are arranged to receive shockwave-only signals. The received signals are analyzed to determine an unambiguous shooter location. The analysis may include measuring the arrival times of the shockwaves of projectiles at each of the sensors, determining the differences in the arrival times among sensors, computing a set of ambiguous solutions corresponding to a shooter, and clustering this set of solutions to determine the unambiguous shooter location. The systems and methods described herein may also be used to determine if multiple shooters are present, and subsequently determine the shooter locations for each of the multiple shooters.

Abstract: Systems and methods for issuing negotiable instruments by a non-bank entity such as a Licensed Money Transmitter, from direct deposits to a regulated financial institution. A customer arranges for direct deposit of funds to a regulated financial institution, such as a bank, that can receive direct deposits. When a direct deposit of funds into an account associated with the customer at the regulated financial institution is detected, the funds are swept into a second, transaction account maintained by the Licensed Money Transmitter. The customer requests issuance of a negotiable instrument from the Licensed Money Transmitter for withdrawing funds or directing that payments be made. The Licensed Money Transmitter, which maintains a network of agent terminals at various locations for disbursing funds to authorized recipients, is responsive to the request for a negotiable instrument for issuing a prepaid negotiable instrument or making payments for the benefit of the customer.

Abstract: Methods and systems of parasitic sensing are shown and described. The method includes, measuring, at a first time using one or more electrical elements native to a domain, a parameter of a circuit within the domain and measuring, at a second time using the one or more electrical elements native to the domain, the parameter. The method also includes, comparing the parameter measurement from the first time to the parameter measurement at the second time and determining, in response to the comparison, that an activity occurred within the domain.

Abstract: A method and apparatus of performing power line sensing is presented. The method and apparatus includes a three-axial vector magnetic sensor for detecting a magnetic field radiated from a power line. An active isolation system is used to determine the effects of noise and other magnetic fields on the three-axial vector magnetic sensor. Power line status information is then determined from data received from the three-axial vector magnetic sensor and the active isolation system.

Abstract: An active noise and vibration control system is constructed such that the residual signal from the residual sensor is fed back into the controller and used to generate the probe signal. Measurements of the residual signal are used to create a related signal, which has the same magnitude spectrum as the residual signal, but which is phase-uncorrelated with the residual signal. This latter signal is filtered by a shaping filter and attenuated to produce the desired probe signal. The characteristics of the shaping filter and the attenuator are chosen such that when the probe signal is filtered by the plant transfer function, its contribution to the magnitude spectrum of the residual signal is uniformly below the measured magnitude spectrum of the residual by a prescribed amount (for example, 6 dB) over the entire involved frequency range. The probe signal is then used to obtain a current estimate of the plant transfer function.
