Title: Distance measuring device
Inventor: GIACOTTO LUCA
IPC: G01S17/10
Filed: 2013-03-05
Abstract: The invention relates to an optoelectronic distance measuring device (99) having a transmitting unit having a driver stage (5) for a light source (6) for emitting optical pulses as pulsed-mode-intensity-modulated optical radiation (10), having a receiving unit for receiving a portion (12) of the optical radiation (10), said portion being reflected from a target object (11), and converting it into an electrical reception signal, by means of a photosensitive electrical component (1).  It also has an analogue-digital converter (3) for digitizing the reception signal, and an electronic evaluation unit (4) which is designed in such a way that a distance (13) from the target object (11) can be ascertained on the basis of a signal propagation time using the digitized reception signal. In this case, the driver stage is designed in such a way that at least two pulse durations (T1, T2, 13) of different length for the optical pulses can be set. A  longer pulse duration (T1, T2, T3) allows the attainment of an extension of a distance measurement range, as a maximum ascertainable distance (13).

Inventor: SOSULIN YURY
IPC: G01S19/22
Filed: 2012-04-24
Abstract: A navigation receiver mounted on a moving vehicle receives navigation signals transmitted from global navigation satellites. The navigation signals are separated into direct navigation signals, navigation signals reflected from an object, and navigation signals reflected from an environmental surface. The signal separation is based on algorithms including various combinations of signal strength, change in signal strength, delay time, spectral width, change in spectral width, and user-defined thresholds. The navigation signals reflected from an environmental surface are eliminated from further processing. The position of the navigation receiver is calculated based on the direct navigation signals. The object is detected, and the position of the object is calculated, based on the navigation signals reflected from the object. If the object is determined to lie in the path of the moving vehicle, a command can be generated to avoid collision between the moving vehicle and the object.

Abstract: Disclosed is a nanostructured device for the in-situ capture of fluid samples at selectable times. The device includes a porous anodic alumina substrate having a plurality of elongated pores and an erodible capping material covering the pores. The device is transported into and through a geological reservoir while suspended in an injected carrier fluid. The device can optionally include a polymeric coating to improve minimize flocculation and sedimentation and prevent adhesion to surfaces in the reservoir. Upon erosion of the capping material, the fluids can diffuse into and fill each exposed pore. After a period of time, the hot water of the medium causes swelling and closure of the pore, effectively locking the fluid sample inside the pore. The device may be retrieved and analyzed to determine the composition and properties of the captured fluids.
