  • Patent number: 10787273
    Abstract: An electrical architecture for an aircraft having a primary three-phase electrical network powering a transformer-rectifier unit serving to power two secondary DC electrical networks. Each of the two secondary electrical networks includes a contactor electrically connected to a generator-starter. The contactors are linked in pairs to prevent them from being closed simultaneously. The second secondary network powers the generator-starter to start a fuel-burning engine. The first secondary network can be powered by the generator-starter to power electrical components. A secondary voltage of the second secondary electrical network is greater than the voltage of the first secondary electrical network, thus making it possible to optimize the weight of the electrical architecture. The two secondary electrical networks may also be powered from autonomous sources of electricity as a replacement for the primary network to power the generator-starter and the electrical components.

    Abstract: Disclosed combination impact tool generates optimized linear hammering and vibrational impacts. Flow of pressurized fluid through an upper section of the tool generates linear hammering impacts, and flow of pressurized fluid through a lower section of the tool generates vibrational impacts. Flow of pressurized fluid through the lower section induces an eccentric arm to rotate and cause vibrational impacts. While frequency of hammering impacts can be controlled by varying pressure of the fluid flowing through the upper section, the frequency and amplitude of vibrational impacts can be controlled by varying weight of the eccentric arm and by varying pressure of the fluid flowing through lower section.

  • Patent number: 10232578
    Abstract: A method of compacting soil via a base machine, the base machine having ram material provided at at least one cable and having a regulation/control apparatus, includes raising the ram material from the land area to be compacted, with a zero point being stored at which no slackline is present. The method further includes raising the ram material to a lift height, carrying out a compaction procedure by dropping the ram material from a drop height onto the land area to be compacted, again raising the ram material from the land area to be compacted, with a further zero point being stored at which no slackline is present, determining and storing a compaction progress, and repeating the previous steps until the compaction progresses of each of a predefined number of consecutive compaction procedures are smaller than or equal to a predefined minimum progress.

  • Patent number: 10177700
    Abstract: In a surgical power tool that includes an electric motor positioned in a housing and a movable element extending from the housing and operatively actuated by the electric motor, a controller can repeatedly interrogate for faults a plurality of components in or on the housing, such as the electric motor, the controller, a battery, a trigger, and a mode switch. Upon finding a component in a fault condition, the controller can engage a critical error handler that disengages the electric motor, disables at least some of the plurality of components, and directs a microprocessor in the controller into a safe software state. Upon engaging the critical error handler, the controller can further write to a memory an error code corresponding to which of the plurality of components is in the fault condition. The error code can be accessible via a wired or wireless connection.

  • Patent number: 10160139
    Abstract: A method to control a power tool including the method steps: specifying the rotational speed of the drive at a first value, measuring a first amplitude of a signal, filtering the signal within a frequency range, measuring a second amplitude of the filtered signal, reducing the rotational speed of the drive to a second value if the first amplitude exceeds a first quantity and if the second amplitude exceeds a second quantity, and incrementally increasing the rotational speed of the drive to the first value, whereby each incremental increase of the rotational speed only takes place once the first amplitude remains below the first quantity for a time interval, and the second amplitude remains below the second quantity. A power tool that uses this method, includes: a drive, an acceleration sensor a filter, and a control unit.

  • Patent number: 10099353
    Abstract: An operation switch sends an ON signal to a control processor indicating the operation switch is triggered by a user. A magnetic sensor sends a sensor signal to the control processor based on a displacement of a chip rod in a rearward direction. In the case where the sensor signal has not yet been sent, the control processor performs a control in a first mode where a brushless DC motor is not driven. In the case where sensor signal is sent, control processor performs a control in a second mode wherein the brushless DC motor is driven. An output in the first mode is lower than in the second mode. Because of this manner of construction, even if an ON input is triggered and held by the user, electric power is conserved while the operation switch is switched on and a hexagonal nut is not fastened, improving power consumption efficiency.
