Abstract: An avionics unit assembly for an aircraft can include an avionics unit (e.g., an underwater locator device, “ULD”), and a battery to power the avionics unit. The avionics unit assembly can further include a housing that encases the avionics unit and the battery. The housing includes a vent port for exhausting an emission from the housing during a failure of the avionics unit. The avionics unit assembly can further include one or more of a suppressor that filters the emission, a shield element that is resistant to chemical and/or thermal effects of the emission, and a bracket for mounting the avionics unit to a surface. A method integrating the avionics unit assembly onto a forward aircraft bulkhead at a mount location under an aircraft radome and for manufacturing the avionics unit, and an aircraft including the avionics unit are also described.

Abstract: A method, system, and computer program product for providing a return on an investment to an endowment that also encourages donations by investing in a vehicles that provide a benefit to the endowed institution. The method includes receiving principal funds from one or more investing entities and receiving data describing an obligation of an endowed institution to pay for goods or services from a supplying entity. The method also includes making a payment to the supplying entity using at least a portion of the principal funds. The method also includes receiving a payment from the endowed institution at a later date for a greater amount than the earlier payment. The payment received from the endowed institution is made at a date later than the payment made to the supplying entity and is an amount that exceeds the payment made to the supplying entity. The method also includes making a payment to an endowment.
