Described techniques receive location data with associated timestamps from one or more location sensors spatially associated with the vehicle. Each pair of consecutive location data defines a segment of the vehicle's trajectory. The system aggregates potential stay periods of consecutive segments into an aggregated stay interval as long as a predefined segment clustering rule is fulfilled by the consecutive segments. A potential stay of the vehicle with a potential stay period for a respective segment is detected if the time interval associated with the respective segment is longer than an expected driving time needed for driving a distance associated with the respective segment at a predefined expected speed. The potential stay period is computed for the respective segment as the difference between the associated time interval and the expected driving time.

Process for producing binderless formaldehyde-free fiberboard and coproducing fulvic acid from straw
A process for producing binderless formaldehyde-free fiberboard and coproducing fulvic acid from straw. All-element purification, activation, saccharification and separation are carried out on the non-wood fiber raw material through boiling and defibering to obtain primarily activated lignin, purified and activated fibers, monosaccharides of hemicellulose and non-wood fibers, and fulvic acid. Deep activation is carried out on activated lignin. The binderless formaldehyde-free fiberboard is produced by using sufficiently activated lignin and low-molecular-weight monosaccharides as a hardener and binder. By sufficiently activating the lignin, comprehensive utilization of straw fiber as resources is realized, and the special requirements of binderless formaldehyde-free fiberboard for high-quality fibrous raw material and high-activity lignin are met. The boiled dilute black liquor was subjected to extraction and concentrated to obtain fulvic acid, thereby avoiding pollution caused by pulping and board production. The distilled water obtained by carrying out evaporative concentration on the boiled dilute black liquor is reused. |

Composite control cables and stabilizing tendons for aircraft applications and method for manufacture of same
Control and stabilizing cables and tendons for high altitude aircraft and airships having lightweight, high strength and low CTE are disclosed, along with a method and machine for fabrication of same. The cable is comprised of a fiber prepreg tow encased in a polymer sleeve with one bobbin at each end to facilitate connections. Consolidating the fiber prepreg tow along the length of the cable using high temperature shrink tubing, such as polyvinylidene fluoride (PVDF), allows for eliminating the twisting of the fiber prepreg tow, thus reducing the number of wraps around the bobbins. Eliminating the twists in the fiber prepreg tow also reduces the length of fiber needed, and therefore the overall change in length of the control cable with temperature variations is reduced. Additional cable strength can be achieved by adding and holding significant tension on the fiber prepreg tow by applying weight during the curing process. |
