A method and system for evaluating and loading unmanned aerial vehicles (UAVs) are described. The UAVs are moved by a conveyance device. It may be determined whether the UAV passes at least one of a structural integrity test or a functionality test. The UAV may be removed from the conveyance device in the event the UAV fails at least one of the structural integrity test or the functionality test. A package may be loaded into a compartment of the UAV in the event the UAV passes the structural integrity test and the functionality test.

Various embodiments of the present invention provide systems and methods for managing fault codes triggered by one or more vehicles during operation. In general, various embodiments of the invention involve recording and analyzing fault codes triggered during a particular time period while a vehicle is in operation. As a result of the analysis, various embodiments of the invention may set a state for each of the identified fault codes, the state indicating a level of action to address the identified fault code. In particular embodiments, the states may be one of a caution state indicating one or more components or sub-systems of the vehicle should be monitored, a critical state indicating one or more components or sub-systems of the vehicle should be repaired, or an environmental state indicating failure or potential failure of one or more components or sub-systems of the vehicle may affect one or more environmental conditions.

An apparatus is adapted to be in electro-mechanically communication with a vehicle and configured to record information related to crash investigation and early warning. The device records and stores information as well as analyzes it to provide an occupant of the vehicle early warning as to potential hazards that arise.

In a method for detecting damage to a component of an aircraft, having an unpressurized first area and a pressurized second area, at least one theoretical pressure parameter, characteristic of a theoretical pressure in the unpressurized first area, a theoretical pressure in the pressurized second area or a theoretical pressure difference between the unpressurized first area and the pressurized second area, is determined. At least one actual pressure parameter, characteristic of an actual pressure in the unpressurized first area, an actual pressure in the pressurized second area or an actual pressure difference between the unpressurized first area and the pressurized second area, is recorded. The theoretical pressure parameter is compared with the actual pressure parameter. Damage to a component of the aircraft causing a compression of the unpressurized first area is detected when a difference between the theoretical pressure parameter and the actual pressure parameter exceeds a threshold value.

A driver history report may include many factors to express performance or quality of driver service. Vehicle event recorders are coupled to systems which form an association between collected data and the vehicle operator in command of the vehicle at the event moment. Systems provide means for long-term storage of data particularly data in a structure which preserves the association between a driver and event records attributed to him. Special recall operations executed against stored data yields operator performance reporting—including a single value performance score indicative of a vehicle operator's performance and safety history. An analyzer system operates to recall data, particularly data from a plurality of events all associated with a single operator but recorded over an extended period of time. Data is arranged such that mathematical analysis may be applied independently to various data elements or data “fields” to produce performance metrics and ratios which reflect performance.

Provided is a method for determining the urgency for repairing a diagnostic condition in a vehicle. Upon determining the repair urgency, a driver may decide to continue driving (in the case of a “low” urgency determination), or cease driving (in the case of a “high” urgency determination). The urgency status may also enable a driver to shop around for the repair (in the event of a “low” urgency status), or to seek immediate assistance (in the event of a “high” urgency status).

A device protecting an aircraft turbomachine computer against speed measurement errors, including: on a speed regulation channel: a speed sensor of a turbomachine gearbox shaft, a speed measurement circuit, and a speed regulation circuit; on a monitoring channel: a speed sensor of a turbomachine gas generator shaft, a speed measurement circuit, and a turbomachine stop control circuit. Each channel uses dissimilar characteristics eliminating common mode errors. Each speed sensor delivers a pseudo-sine frequency signal. On each channel, speed monitoring circuits compare the frequency signal with a minimum threshold, delivering an error signal when the measured frequency is lower than the minimum threshold. A common speed cross checking circuit detects exceeding a determined deviation between both frequencies, the monitored deviation being higher or lower than a maximum deviation corresponding to loss of a frequency period on either sensor. Analyzing the error signals, exceeding the determined deviation can control stopping the turbomachine.

A system for receiving a driving event comprises an interface and a processor. An interface is configured to receive a portion of data regarding a driving event. A processor is configured to determine whether more data regarding the driving event should be requested and, in the event that more data regarding the driving event should be requested, request more data regarding the driving event.
