Abstract: A heat exchange system for an aircraft engine includes a heat exchanger, a main conduit directing fuel to a combustion chamber of the aircraft engine, and a pump connected to the main conduit. A return conduit receives excess fuel outputted by the pump and exceeding a fuel requirement of the combustion chamber. The return conduit, which is connected to a fuel conduit of the heat exchanger, has an inlet connected to the main conduit downstream of the pump and an outlet connected to the main conduit upstream of the pump. An actuator has an inlet connected to the main conduit downstream of the pump and an outlet connected to the main conduit upstream of the pump while bypassing the heat exchanger, wherein a pressure differential between the actuator inlet and the actuator outlet remains substantially unchanged with variations of a fuel flow through the heat exchanger.

Abstract: The heat exchanger system can have a first conduit extending from at least one first conduit inlet through a heat exchanger to at least two first conduit outlets; a second conduit extending from at least one second inlet through the heat exchanger to at least one second outlet, the first and second conduits disposed adjacent to one another in heat exchange engagement within the heat exchanger; and a bypass conduit extending from the first conduit between the at least one first inlet and the heat exchanger to the first conduit between the heat exchanger and at least one of said at least two first outlets.

Abstract: The liquid cooling system has a heat exchanger having a fluid inlet and an outlet; a fluid supply conduit leading to the inlet of the heat exchanger; a fluid return conduit extending from the outlet of the heat exchanger; a bypass conduit extending between the fluid supply conduit and the fluid return conduit; a thermal valve configured for selectively closing the bypass conduit, the valve having a temperature sensing element positioned downstream of both the heat exchanger and the bypass conduit, the temperature sensing element configured to selectively move the thermal valve in response to a temperature change of the liquid which the temperature sensing element is exposed to relative to a temperature threshold of the valve; and a deflector positioned between the temperature sensing element and at least one of the bypass conduit and the heat exchanger outlet.

Abstract: A memory device has a plurality of memory blocks utilized to store data. One of the blocks is used as a hidden memory block to store an operating system program, instead of data. The hidden memory block is designated as a bad block so that data will not be written into the hidden memory block, but a tag associated with the hidden memory block identifies that the hidden memory block contains the operating system program.

Abstract: A method for booting a system on a chip (IC) integrated circuit includes reading a warm boot flag stored in a persistent register of an analog portion of the system on a chip IC. A warm boot procedure is executed when the warm boot flag is set.

Abstract: A method, system and program product to simultaneously download and burn digital media files via the Internet, including audio, video, video games and other digital content and data, onto removable storage media on personal computer burners. Large media files can be downloaded by pushing files or portions of files to computer memory and simultaneously downloading and burning files selected by a user. Once a file is burned to disc, it is then deleted from the computer's memory. A lossless compression scheme is used for audio files to decrease file size, making the downloading process faster and requiring less hard drive space. Content files other than audio are downloaded and burned through the same one-step process, without using a lossless compression scheme. An alternative method delays the start of the burn process to ensure that the downloaded files are written continuously to the removable storage media.
