Abstract: The present disclosure describes methods and systems for facilitating the verification of a service provider (SP) by an end user (EU). The disclosed system allows an EU, which may be a person, system, or company, to verify the legitimacy of an SP or SP personnel before granting access to sensitive information or systems. The system supports multiple verification mechanisms, including SMS, email, and client portals, to ensure secure and reliable verification. The verification process involves the exchange of randomly generated codes between the EU and SP, which must match to confirm the SP's identity. The system also includes features for logging verification requests and responses, integrating with service desk platforms, and providing multi-factor authentication (MFA) to enhance security.

Abstract: Methods for reducing electromagnetic interference arising from use of multiple ultrasound transducers in an array, particularly inside a human body that is inside a magnetic resonance imaging device. Electrical signals driving the transducers are offset in phase with respect to one another so as to achieve maximum offset of electrical and magnetic fields arising from such signals and transducers. Phase offsets are dynamically adjusted to respond to changes in driving amplitudes and frequencies so as to maintain optimal reduction of electromagnetic interference.

Abstract: An aircraft lifting assembly includes a jack, a load cell, and a jack adapter. The jack includes an extendable arm having a distal end portion for exerting a force to lift an object. The distal end portion defines a cavity. The jack adapter couples the extendable arm to the load cell and includes a base portion, a cradle portion, and a projection. The base portion defines a jack arm support surface and a load cell support surface. The jack arm support surface opposes the distal end portion of the extendable arm and the load cell support surface opposes the load cell. The cradle portion extends from the base portion to circumscribe a portion of the load cell to secure the jack adapter to the load cell. The projection extends from the base portion into the cavity to secure the jack adapter to the extendable arm of the jack.

Abstract: A multi-frequency ultrasound therapy apparatus is configured to operate at its center frequency and at the higher harmonic of its center frequency. The center frequency can be for the entire apparatus or for each ultrasound source element. At least one source element can generate ultrasound energy at its center frequency while, simultaneously, at least another source element can generate ultrasound energy at the higher harmonic of its center frequency. In addition, the same source element can generate ultrasound energy at its center frequency and the higher harmonic of its center frequency, respectively, but at different times. A data storage unit that stores encrypted and encoded data is disposed on the apparatus. The encoded data includes a unique identification code of the apparatus, the condition of use of the apparatus, the center frequency of each source element, the ultrasound efficiency of each source element, and/or other parameters relating to the apparatus.

Abstract: A fuel drain engagement tool and a method for draining fuel from a fuel tank are provided. In one example, a fuel drain engagement tool includes a housing. An engagement mechanism is coupled with the housing and extending upward therefrom. The engagement mechanism is configured to engage a fuel drain valve and to move between a contracted state and an expanded state. A compression applicator is coupled with the housing and is positioned to engage the engagement mechanism when the compression applicator is compressed to apply a force to the engagement mechanism that causes the engagement mechanism to move from the expanded state to the contracted state.

Abstract: A tool for adjusting an orientation of a nose landing gear of an aircraft is disclosed herein. The nose landing gear has an axle to which a wheel is mounted. The axle has an opening extending therethrough. The opening is defined by an inner surface of the axle. The tool includes, but is not limited to, a unitary member having a handle portion at a first end of the unitary member and an axle-engaging portion at a second end of the unitary member. The handle portion is configured for engagement with a hand of an operator. The axle-engaging portion is configured to be inserted into the opening and to engage with the inner surface.

Abstract: Temperature uncertainty maps are calculated based on a rolling window of temperature maps, which is updated as new temperature maps are generated. The rolling window mitigates the effect of transient motion during a thermal therapy procedure. A clinician or an automated control system can then update a portion of an anatomical boundary or the thermal therapy applicator center based on the temperature uncertainty map.

In one example, a cradle assembly includes a first contoured board and a second contoured board that is spaced apart from the first contoured board. The first and second contoured boards are cooperatively configured to support outer sections of a first door. A third contoured board is configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door. The third contoured board is contoured to substantially match the first outer section of the second door. The cradle assembly is configured to be positioned proximate to the fuselage.
