  • Patent number: 10386383
    Abstract: A waveguide arrangement for measuring the speed of a projectile during passage through a weapon barrel arrangement includes a main waveguide and at least one auxiliary waveguide. The main waveguide has a cross-section suitable for the passage of the projectile. The auxiliary waveguide extends adjacent to the main waveguide and is connected to the main waveguide via an opening. An isolator is arranged in the auxiliary waveguide. The waveguide arrangement is particularly suited for large-caliber ordinance and has at least one coupler extending at least partially in the isolator. The speed of the projectile in the main waveguide is measured at a frequency below the limiting frequency. The transmitting coupler is arranged at a spacing distance from the muzzle in order to prevent an exit of the generated signal from the weapon barrel arrangement.

  • Patent number: 10197665
    Abstract: A radar detector suppresses alerts from vehicle guidance systems, by sweeping for a consistent radar signal; the center frequency of the signal is stored and the detector suppresses warnings of radar signals near that frequency. The detector uses an enhanced method for suppression of signals near a known location of a false signal source; in the event the detector detects a radar signal and finds a matching stored false signal, the detector will first compare the strength of the received signal to a threshold strength that is computed based upon the distance of the detector from the stored false signal, and will only suppress signals below threshold. The detector includes a camera directed to the road in the vicinity of the vehicle. Image data from the camera is processed to identify police vehicles as identified by flashing lights, a profile including a rooftop light bar and/or highly contrasting colored panels.

  • Patent number: 9261581
    Abstract: Static transmitter stations are used to determine the position of a mobile receiver unit. Each transmitter station transmits an ultrasonic signal including a transmitter-specific phase-shifting signature. The receiver unit receives a signal and identifies a transmitter station by its signature. It uses the received signal and the identity of the source transmitter station to determine the position of the mobile receiver unit. The signature may include two patterns phase-shift-key (PSK)-encoded on respective carrier signals of the same frequency but different phase, with the patterns being offset from each other by a transmitter-specific offset. The signal from the transmitter station may also include a PSK-encoded message.

  • Patent number: 9213085
    Abstract: The invention is related to phase detection in lidar systems using single photon detectors (SPDs). The frequency at which the SPDs are time gated is related to but not an integer multiple of the frequency of the transmitted optical pulses. Each return optical pulse arrives with a particular temporal position with respect to the nearest gate, and thus is detected with a related detection efficiency. The SPD output can be segmented into multiple time-multiplexed signals whose relative detection efficiency reveals the phase of the optical return pulses, and no such phases have negligible detection efficiency for all the time-multiplexed signals. To mitigate the impact of afterpulsing and other saturation effects, when a first optical pulse is detected with high detection efficiency the next optical pulse that is detected with high detection efficiency is separated by a time period about equal to or greater than the detector dead time.

    Abstract: Hydrocarbon fuel is sent to a reformer, which produces carbon and hydrogen. The hydrogen is sent to a fuel cell which uses it to generate electricity, and the electricity is used to actuate an electric motor that is coupled to an output shaft of a turbine to impart torque to the shaft. Additionally, hydrocarbon fuel can be provided to the turbine intake directly and/or carbon from the reformer can be mixed with steam from the fuel cell and sent to the turbine intake, in either case to impinge on the turbine blades and impart further torque to the output shaft.

  • Patent number: 9046607
    Abstract: A radar system includes an arithmetic processing unit, which sends a warning command to a warning device when a local minimum point of the intensity of the reflected wave from a target within a predetermined detection range is detected. By determining whether it is necessary to send a warning command based on whether there is a local minimum point of the intensity within the detection range, it is made possible to determine whether it is necessary to send a warning command more quickly as compared to the conventional system.

  • Patent number: 9041594
    Abstract: An RF beam is used to probe the presence or absence of a rotating blade in a known field of view. Timing of appearance or disappearance or “zero-crossing” of a reflected signal is correlated with timing of the blade movement. Blades which are leading or lagging versus other blades will produce different timing signatures representative of alignment of the blades.

That processor may also have a network interface media access controller, where the system operates at different ranges, the modulator may produce pulses of two pulse patterns differing in pulse duration and inter-pulse spacing, those pulse patterns are introduced and used to form two radar images with the two images being derived from data acquired in a duration not more than twenty times larger than the larger inter-pulse spacing, or for a radar system, larger than one half of the antenna resolution time. One or more look-up tables may be used to control the amplifier.
