The invention relates to an electronic control device for a brake system of a motor vehicle, comprising at least one interface for an operating element, in particular a parking brake operating switch, and at least two actuating circuits for electrical actuators, in particular electrical parking brake actuators. According to the invention, the electronic control device comprises two or more independent processors, which are directly connected to each other via a data bus. A motor vehicle equipped with a control device or brake system according to the invention requires no transmission lock in an automatic transmission.

A control unit of an electric power converter, which is used in a three-phase motor having two winding wire systems, performs for a first duty instruction signal regarding a voltage applied to a first winding wire group a flatbed two-phase modulation process, and performs for a second duty instruction signal regarding a voltage applied to a second winding wire group a flattop two-phase modulation process. By phase-shifting the second duty instruction signal by 30° from the first duty instruction signal, a timing of maximum value of the first duty instruction signal is shifted from a timing of minimum value of the second duty instruction signal. Even when the maximum value is greater than a center output value and the minimum value is smaller than the center output value, overlapping of capacitor discharge is avoided, thereby reducing a ripple electric current.

The invention relates to a hydraulic brake system for a vehicle. Here, the hydraulic brake system has a force / pressure conversion element which is in hydraulic connection with at least one wheel brake cylinder of at least one wheel. Furthermore, the hydraulic brake system comprises a volume adaptation element in hydraulic connection with the at least one wheel brake and the force / pressure conversion element, and an actuating unit for actuating the force / pressure conversion element. Moreover, the actuating unit has an input element. The pressure in the at least one wheel brake cylinder, that is to say the brake pressure is set by operation of the volume adaptation unit and / or the actuating unit. To this end, it is provided that an actuating state of the input element is maintained by operation according to the invention of the actuating unit during operation of the volume adaptation unit.

A method and system for reviewing and recording approvals for a component requirements document (CRD). A document link to a CRD and a chart link to a condensed version of the CRD are inserted into a review database table. The CRD describes changes required for a software application component. Prior to a review meeting, reviewers activate the document link to display the CRD. During the review meeting, the reviewers activate the chart link to display the condensed version of the CRD for a review of the required changes. An annotation is inserted into the review database table in response to completing the review. The annotation indicates a readiness for an approval process in which the CRD is approved by approvers. A comment link to a sign off comment is inserted into a sign off database table. The sign off comment indicates an approval of the CRD.

A servo control apparatus which includes: a difference calculation unit that calculates difference between an integral value of speed deviation of a master axis and an integral value of speed deviation of a slave axis; a filter unit that performs filtering of the difference by way of a low-pass filter; and an addition unit that adds a result of the filtering to the integral value of the speed deviation of the slave axis, in which a current command for driving the master-axis motor is calculated for the master axis by using the integral value of the speed deviation of the master axis; and a current command for driving the slave-axis motor is calculated for the slave axis by using an integral value after addition by way of the addition unit.

First pulse width modulation control is a control of generating a first pulse width modulation signal for a plurality of switching elements by comparison of modulated waves of voltage commands in phases based on a torque command for a motor with a carrier voltage, and performing switching of the plurality of switching elements. Second pulse width modulation control is a control of generating a second pulse width modulation signal for the plurality of switching elements based on a modulation factor of a voltage and a voltage phase based on the torque command and the number of pulses per unit period of an electrical angle of the motor, and performing switching of the plurality of switching elements. An electronic control unit is configured to switch the plurality of switching elements between the first pulse width modulation control and the second pulse width modulation control at irregular time intervals.

The automatic board jointer comprises a rack, an upper heating mechanism, a lower heating mechanism, a board pressing mechanism, a turning mechanism and a pushing mechanism, and is characterized in that the pushing mechanism comprises a pair of pushing plate acting cylinders, a pushing plate and a pair of pushing plate synchronization devices, wherein the upper heating mechanism comprises a group of upper heating tubes and an upper heating tube heating medium lead-in and lead-out header pipe; the lower heating mechanism comprises a group of lower heating tubes and a lower heating tube heating medium lead-in and lead-out header pipe; a group of upper and lower heating tubes form a board line shifting passage; the board pressing mechanism is fixedly arranged on the upper heating tubes; the turning mechanism comprises a turning acting cylinder, a turning arm, a turning plate shaft and a turning plate. The pushing plate can achieve a good integral movement effect; the movement resistance of the pushing plate is obviously reduced; the turning plate can be reliably kept in a control state of the plate after turning, collapse of plates in a laminated state is avoided, and normal work of the board pressing mechanism and the pushing mechanism is guaranteed.

The present invention provides a play toy system using a remote-controlled traveling toy, which enables the remote-controlled traveling toy to make a movement that is more unexpected than before, for play. The remote-controlled traveling toy 1 includes one front wheel 5 and two rear wheels 7 and 9. The traveling toy is remotely controlled by remote control signals and is so constructed as to travel on a traveling surface of a play board. The diameter sizes of the two rear wheels 7 and 9 are different. With one front wheel 5 and two rear wheels 7, 9 having a different diameter, the remote-controlled traveling toy 1 can move most unexpectedly that anyone has ever experienced, according to the state of the traveling surface of the play board.

An aircraft includes a fuselage and a pair of channel wings which may vary incidence with respect to the fuselage and a pair of channel canards which can also vary incidence with respect to the fuselage and that can move independently of each other for the purpose of vertical takeoff and landing as well as forward and reverse flight. The wings may have multiple channels and may be powered by single propeller or contra-rotating propellers. The thrust to the propellers may be provided with an internal combustion engine or electric motors or a turbo prop or hybrid system. The channel wing allows the fuselage to maintain a level pitch with respect to the horizon. The aircraft will also have increased maneuverability in hover because it can independently vary the incidence of the wings and canards and be able to tightly turn about a point.
