Each radio stores a channel plan of pre-determined base transmit times, and calculates a worst case time drift between clocks and a propagation delay value between combinations of radios. At each base transmit time, if a radio has an outgoing message to transmit, it subtracts propagation delay from the base transmit time, and transmits only at that time. Also, for each base transmit time, each radio subtracts time drift, thereby determining a receive time window during which it listens for messages from other radios. |

Method for detecting particulate radiation
When detecting particulate radiation, such as electrons, with a pixelated detector, a cloud of electron/hole pairs is formed in the detector. Using the signal caused by this cloud of electron/hole pairs, a position of the impact is estimated.

Thin and flexible solid electrolyte for lithium-ion batteries
A lithium-ion conducting, solid electrolyte is deposited on a thin, flexible, porous alumina membrane which is placed between co-extensive facing side surfaces of a porous, lithium-accepting, negative electrode and a positive electrode formed of a porous layer of particles of a compound of lithium, a transition metal element, and optionally, another metal element. A liquid electrolyte formed, for example, of LiPF6 dissolved in an organic solvent, infiltrates the electrode materials of the two porous electrodes for transport of lithium ions during cell operation. But the solid electrolyte permits the passage of only lithium ions, and the negative electrode is protected from damage by transition metal ions or other chemical species produced in the positive electrode of the lithium-ion cell. |
