V2X messaging in 5G/6G with simultaneous GPS reception
Wireless communication in 5G or 6G, between vehicles (V2V) and other entities (V2X), offers vast opportunities for collision avoidance and improved traffic flow. Many of these opportunities depend on localizing and identifying particular wireless entities (vehicle, pedestrian, base station, toll booth, security gate, among innumerable others). However, due to vehicle motion, the spatial resolution achievable with satellite signals such as GPS, is generally too poor (several meters) to reliably localize a particular wireless entity, inhibiting many applications. Greatly improved localization may be achieved by arranging for multiple vehicles to acquire the satellite signals at the same time from the same satellites. They then transmit parameters of the satellite signals to a calculating entity (such as one of the vehicles) which then processes the data differentially, determining the relative distances between vehicles. Many errors and uncertainties may thereby cancel. The calculating entity can then broadcast a message indicating the coordinates and wireless addresses of the vehicles. With sub-meter spatial resolution, vehicle localization may be improved, cooperation between vehicles may be enabled, and many collisions may be avoided, saving countless lives, according to some embodiments. |

Efficiency is further enhanced by using a combination of single-precision and double-precision floating-point units to generate the samples of the transmitter signals with single-precision floating-point. All subsequent calculations are then computed in single-precision. |

A precise optical technique for measuring electronic transport properties in semiconductors is disclosed. Using tightly focused laser beams in a photo-modulated reflectance system, the modulated reflectance signal is measured as a function of the longitudinal (Z) displacement of the sample from focus.

System and method of using energy correlated timing spectra to locate subsurface objects
Multiple tagged neutrons are emitted from an associated particle imaging neutron generator. The tagged neutrons penetrate a target material and interact with the target material nucleus—which emits nucleus-specific gamma rays. A gamma ray detector detects all gamma rays—including the nucleus-specific gamma rays. An alpha-gamma timing spectrum is constructed for all detected gamma rays. For a specific energy level (MeV) corresponding with the target material nucleus, a peak in the alpha gamma timing spectrum indicates the presence of the target material. Based on the peaking time of the gamma rays (due to tagged neutrons interaction with the target material nucleus) in the alpha-gamma timing spectrum for the specific energy level, the distance from the neutron generator to the target material can be calculated. The nucleus-specific gamma ray spectrum data can be effectively collimated by programming the system to detect the gamma rays in a time window corresponding to the peaking time. |
