The invention relates to a method and a device for determining a return time of a returning light pulse by a Single Photon LiDAR scanner, in the following called SPL scanner, in particular in an aerial LiDAR surface scan, a terrestrial monitoring scan, a mobile mapping scan, or a construction or surveying scan, in particular for measuring the time between an outgoing pulse event and a return pulse event, the SPL scanner comprising of a low photon count detector for converting low amounts of photons or single photons to electrical signals, and a control and processing unit for processing the data and for determining the return time of the returning light pulse. The method is characterized in that the control and processing unit identifying a group of detected photons potentially representing a return pulse event and creating a return pulse signal based on a criterion involving a temporal probability distribution for the detected photons, in particular a defined minimum of consecutively detected low amounts of photons or single photons, identifying a rising edge and a falling edge of the return pulse signal based on the identified group of detected photons potentially representing a return pulse event, and determining the return time for each return pulse event based on the rising edge and the falling edge of the return pulse signal.

An improved slider for use with a parachute, particularly a ram-air type parachute, is provided. The slider includes a generally rectangular piece of material having grommets in the corners through which the suspension lines of the parachute run. At least one retaining structure is attached to or made in the slider material for securing one or more stiffening elements. The stiffening elements are flexible enough to allow for the packing of the parachute, but stiff enough to keep the material of the slider spread open in the fore/aft direction across the short axis of the slider and thereby prevent the slider from folding and flapping once the canopy has opened.


A method for monitoring a primary field dipole moment in a TDEM geological surveying system, including measuring a sign and amplitude of a primary field generated by a transmitter loop and sensed by a receiver in each of a plurality of sensitive axes, and in dependence thereon calculating a vector which represents orientation of the primary field at the receiver location in a receiver frame of reference; and determining, in dependence on the vector an orientation of the primary field dipole moment in a receiver frame of reference.

The invention relates to a method and a hybrid 3D-imaging device for surveying of a city scape for creation of a 3D city model. According to the invention, lidar data is acquired simultaneously with the acquisition of imaging data for stereoscopic imaging, i.e. acquisition of imaging and lidar data in one go during the same measuring process. The lidar data is combined with the imaging data for generating a 3D point cloud for extraction of a 3D city model, wherein the lidar data is used for compensating and addressing particular problem areas of generic stereoscopic image processing, in particular areas with unfavourable lighting conditions and areas where the accuracy and efficiency of stereoscopic point matching and point extraction is strongly reduced.

An aerial delivery platform comprises first and second modules (10a, 10b) each having a respective load-bearing surface (14). The modules (10a, 10b) are hinged together for relative flexing movement about an axis (24) between the modules (10a, 10b). A superstructure of interconnected struts (25, 26, 27, 28, 29) is connected to, and is upstanding from, the modules (10a, 10b) to hold the modules (10a, 10b) with the load bearing surfaces (14) coplanar when loaded and during descent but being elastically deformable to permit limited relative flexing movement between the modules (10a, 10b) under the loads applied by parachute opening and on landing to assist in the absorption the energy transferred to the platform.

A basketball training system includes a basketball training machine, a wearable physiological monitor, a wearable player motion monitor, and a ball motion monitor. Data from the training machine and the monitors is used to provide feedback to the player on shooting performance, shooting form and technique, and intensity level of the workout. The system can provide programmed workouts that include shooting drills and exercise segments to combine shooting practice with conditioning.

A basketball training system includes a ball delivery system in which a basketball is delivered to a ball ready holder located in front of a ball launch mechanism. A launch arm is grabbed and pulled backward against a spring force, and then is released to pivot forward and strike the basketball from the ball ready holder.
