Abstract: Various embodiments of the present disclosure provide an aircraft engine monitoring system. Generally, the aircraft engine monitoring system includes an engine monitoring device and one or more sensors configured to sense engine parameters of an engine of an aircraft and to generate and send signals representing the sensed engine parameters to the engine monitoring device, which stores them as engine performance data. An external device is communicatively connectable to the engine monitoring device to retrieve the engine performance data if both (1) the engine monitoring device determines that the external device is a trusted device and (2) the external device determines that the engine monitoring device is a trusted device, the engine monitoring device is configured to encrypt and securely transmit some or all of the engine performance data to the external device.

Abstract: Apparatus and methods for a temporary marker are described. The temporary marker can be made at home by a user having basic computer and printing capabilities, without the need for commercial printing or design equipment. The temporary marker consists of a synthetic sheet of paper that can be fed through a home printer and mounted between two sheets of hard, transparent material. The two sheets of hard, transparent material attach to one another with the sheet of paper secured between. A stake is then added to the two sheets of transparent material so that the temporary marker can be secured into the ground. Also, computer software may be provided that allows for easy formatting and input of various texts and images to be printed onto the paper.
