One or more devices in an accident detection and recovery computing system may be configured to determine that vehicle accidents have occurred, collect and analyze accident characteristics and other related data, and providing customized accident recovery services. Mobile computing devices, alone or in combination with vehicle-based systems and external devices, may detect accidents or receive accident indication data. After determining that an accident has occurred, mobile computing devices and/or vehicle-based systems may be configured to determine accident characteristics, retrieve vehicle data and vehicle occupant data from one or external servers, determine the damages or potential damages resulting from the accident, and determine one or more accident recovery options or recommendations based on the accident damages. Various user interface screens may be generated and displayed via the user's mobile device and/or a vehicle-based display device to provide the user with accident information, damages, and recovery options or recommendations.

Sensors, devices, systems, devices, and methods for providing wireless modular self-contained units with battery power supply that can use radar, ultrasonic, and IR measuring techniques and sensors for directional detection of impeding objects, persons, or moving targets, and can be used with mobile smart phones and the like. The modular sensor units can be used as a displacement and motion measurement sensor for point of reference measurement applications. The displacement sensing method can use radar, ultrasonic, and IR measuring techniques for directional detection of impeding objects, persons, or moving targets. Upon the detection of the said target, algorithms make use of the direction, angle of ascent, and speed to provide real time position data represented in discrete format. The said sensors are modular in embodiment allowing for multiple sensors to be positioned in strategic regions on the person or system of interest to study the said frame using the method of moments to dissect the object in varying degrees of granularity. The sensor shall connect wirelessly to a mobile handheld (i.e. the end user's smartphone) device for real-time data acquisition along with seamless integration into an existing IMU only based system requiring information beyond six degrees of freedom as normally represented by gyros, and accelerometers.

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.
