The present disclosure provides a compression hosiery designed to be worn on a human leg. The compression hosiery includes a first portion adapted for a lower portion of a human leg and having a first pressure gradient slope and a second portion adapted for an upper portion of a human leg and having a second pressure gradient slope. The pressure gradient slopes generally decrease in a direction from the first portion to the second portion such that the compressive forces at the first portion are greater than the compressive forces at the second portion when the hosiery is worn.

A power-factor-corrected power supply adapted to supply power to one or more light emitting diodes (LEDs), comprises: a triac dimmer electrically connected between an alternating current source and a bridge rectifier; a damping circuit electrically connected between the alternating current source and the bridge rectifier; a bleeder circuit configured to conduct current between a supply terminal of the bridge rectifier and ground only when a triac in the triac dimmer is not conducting current; a fast startup circuit configured to conduct current between the supply terminal of the bridge rectifier and a voltage supply terminal of a power-factor-corrected controller when the triac dimmer is initially turned on until a supply voltage capacitor coupled to the voltage supply terminal of the power-factor-corrected controller has charged; a dimming slope control circuit configured to reduce a first voltage sensed at a current sensing terminal of the power-factor-corrected controller, such that a reduced amount of current is supplied to the one or more LEDs at a given firing angle, wherein the first voltage is representative of a current flowing through a primary winding of a flyback transformer; and a dummy load circuit provided in parallel with the one or more LEDs to draw a holding current for the triac only after the triac is turned on.

The present invention concerns measures for the space-optimized determination of printing-related measured values. With the aid of a tone value and / or color gradient in a control patch and a suitable measuring device, it is possible to obtain, in a smaller amount of space, adequate or even detailed information about the printing process. Correcting values necessary for the automatic control of the printing operation can be determined on the basis of the information thus obtained, which can be also be continuously acquired due to the space-optimized tone value and / or color gradients.

At least one rotating component of at least one printing unit is regulated to a target value for a temperature, representing the component temperature, by a temperature controller. At least one drive of an assembly of the printing machine is regulated or controlled, on the basis of a target value for a rotational speed prescribed by a command level, with respect to a rotational speed to be maintained. For at least an operating phase transient, relative to the rotational speed, a target value prescribed by the command level, is modified. This is done by considering at least one member of a route and / or a control model characterizing the temperature controller and / or by using a rule (F2(θ)) for a dependence of a rotational speed on a temperature. The modified target rotational speed serves as a prescribed value for the rotational speed of the drives.

A magnetorheological actuator including a chamber, in particular a chamber at least sections of which are shaped like a hollow cylinder, containing a magnetorheological fluid, and further including a control element disposed in the chamber, wherein the control element suitable for applying the operating force of the actuator, wherein the control element is a threaded spindle or screw or threaded rod driven to rotate about its longitudinal axis, in particular about the screw axis, and including a spindle core and a thread disposed thereon, the thread surrounded by the magnetorheological fluid, is provided. A clutch having such an actuator is also provided.

A voltage controlled oscillator (VCO) includes a VCO unit having multiple VCO unit output terminals and an amplifier having multiple amplifier output terminals respectively connected to the VCO unit output terminals. The VCO unit generates first output signals having an oscillation frequency corresponding to a supply voltage. The amplifier amplifies a value obtained by performing n-th differentiation on a transconductance component of each first output signal (n being a natural number). Second output signals, corresponding to the first output signals, are output through the amplifier output terminals. Each second output signal includes the amplified value of the corresponding first output signal.

The invention provides a washing machine and a balancer. The washing machine includes an annular ball balancer in a washing tub about a vertical axis. The ball balancer includes a plurality of balls, a viscous fluid, a balancer case having an annular ring space defined therein, the ring space being partitioned into a bottom surface, top surface, inner circumferential surface, and outer circumferential surface, and a plurality of division plates to partition the ring space into a plurality of arc-shaped divided spaces. The viscous fluid and at least one of the balls are received in each divided space. Each divided space is provided at a portion thereof corresponding to the bottom surface with an inclined surface downwardly inclined from one end of each division plate to a deepest part in a circumferential direction. The deepest part of each divided space is located at a position where weight balance of the balls is achieved in a stop state.
