The Direct Electric Resistance Liquid Heater comprises a liquid heating chamber containing a plurality of electrodes. The electrodes are spaced apart to create a plurality of channels through which the liquid to be heated passes. The electrodes are each connected to a power supply by one or more switches. A controller controls the switches based upon data received from a temperature sensor, sensing the temperature of the liquid, and / or an electric current sensor, sensing the current utilized by the liquid heater. Selection of the number and spacing of the electrodes, and the number of switches, provides the controller with various current levels options to apply to the liquid to be heated. The current levels available due to the number and spacing of the electrodes and the number of switches, span the range from minimum current to maximum current such that the controller can incrementally increase or decrease the current applied to the liquid to be heated without disrupting other users of the same power source.

A cardiac rhythm management system is capable of treating irregular ventricular heart contractions, such as during atrial tachyarrhythmias such as atrial fibrillation. A first indicated pacing interval is computed based at least partially on a most recent V-V interval duration between ventricular beats and a previous value of the first indicated pacing interval. Pacing therapy is provided based on either the first indicated pacing interval or also based on a second indicated pacing interval, such as a sensor-indicated pacing interval. A weighted averager such as an infinite impulse response (IIR) filter adjusts the first indicated pacing interval for sensed beats and differently adjusts the first indicated pacing interval for paced beats. The system regularizes ventricular rhythms by pacing the ventricle, but inhibits pacing when the ventricular rhythms are stable.

There is provided a matrix converter apparatus including both functions of outputting a step up voltage and outputting a step down voltage. In a matrix converter apparatus for directly connecting respective phases of a three phase alternating current power source (1) and respective phases of an output side by a bidirectional switch constituted by IGBT transistors or the like connected reversely in parallel therewith, controlling to output an alternating current power source voltage by a PWM control based on an output voltage instruction, and outputting an arbitrary direct current or alternating current voltage, respective reactors (61), (62), (63) inserted to be connected between the respective phases of the polyphase alternating current power source 1 and the bidirectional switches are included, and by controlling to ON / OFF the bidirectional switches, terminals of two or more of the reactors on a side of the bidirectional switch are shortcircuited, and thereafter opened to thereby step up an output voltage of the matrix converter apparatus. Further, when the terminals are switched from being shortcircuited to being opened, conduction paths of currents flowing in the respective reactors which have been shortcircuited are ensured by controlling to ON / OFF the bidirectional switch group (5) and a capacitor group (7).

An organic light emitting diode (OLED) display includes a display panel including data lines, scan lines crossing the data lines, and pixels which each include an organic light emitting diode and are arranged in a matrix form, a power generator which is enabled in a normal mode to generate a high potential power voltage for driving the display panel and is disabled in a low power mode, and a panel driving circuit which drives the data lines and the scan lines, disables the power generator in the low power mode to cut off an output of the power generator, and supplies an internal power less than the high potential power voltage to the display panel to reduce the high potential power voltage in the low power mode.

In a device for controlling an engine, comprising combustion noise suppressor for suppressing combustion noise of a combustion chamber and controller for controlling the combustion noise suppressor, the device further includes control amount setter for setting a control amount of the combustion noise suppressor so that target combustion noise characteristics corresponding to a required amount of acceleration or deceleration exhibit a slower change in combustion noise than combustion noise characteristics corresponding to output characteristics of the engine over before and after acceleration or deceleration, wherein the controller controls the combustion noise suppressor according to the control amount set by the control amount setter. On the event of a rapid acceleration, a rapid change in the combustion noise in the initial stage of the acceleration is prevented to improve driving comfort.

A method for regulating an actuator for a control surface is provided, which actuator has an angular position controlled by an autopilot on an aircraft with mechanical flight control. When the value of the torque exerted by the actuator is less than a threshold torque value, the actuator is regulated in terms of position and the maximum speed of movement of the control surface is limited to a value that is dependent on the torque value. When the value of the torque exerted by the actuator is greater than the threshold torque value, the actuator is regulated in terms of torque.
