Patents by Inventor Jean-Francois Genat

Jean-Francois Genat has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8934593
    Abstract: The invention provides a device including a binary pulse input signal converter, the output of which is connected to a counter and to a delay line that includes a plurality of delay elements. The counter and the delay line also receive a clock signal as an input. The delay line is combined with a sampler and analog memory that includes a plurality of storage cells that receive the input signal as input. Each element of the a delay line includes an output connected to a corresponding storage cell of the analog so as to sequentially control the sampling and storage of the input signal in the storage cells.

  • Publication number: 20140183369
    Abstract: Large-area, flat-panel photo-detectors with sub-nanosecond time resolution based on microchannel plates are provided. The large-area, flat-panel photo-detectors enable the economic construction of sampling calorimeters with, for example, enhanced capability to measure local energy deposition, depth-of-interaction, time-of-flight, and/or directionality of showers. In certain embodiments, sub-nanosecond timing resolution supplies correlated position and time measurements over large areas. The use of thin flat-panel viewing radiators on both sides of a radiation-creating medium allows simultaneous measurement of Cherenkov and scintillation radiation in each layer of the calorimeter. The detectors may be used in a variety of applications including, for example, medical imaging, security, and particle and nuclear physics.

  • Patent number: 4719608
    Abstract: A chain of gates is formed on one and the same substrate of integrated circuit to enable the propagation along the chain of a starting signal received at one end of the chain, and a locking circuit formed for example by another chain of gates has outputs connected to the gates of the chain in order to be able to block the state thereof following the reception of a stop signal, so that the number of gates gone through by the starting signal is a linear function of the time elapsed between the reception of the starting signal and the reception of the stop signal.
