Abstract: The invention relates to a substrate holding and locking system for chemical and/or electrolytic surface treatment of a substrate in a process fluid and a corresponding method. The system comprises a first element, a second element, a reduced pressure holding unit and a magnetic locking unit. The first element and the second element are configured to hold the substrate between each other. The reduced pressure holding unit comprises a pump to reduce an interior pressure inside the substrate holding and locking system below atmospheric pressure. The magnetic locking unit is configured to lock the first element and the second element with each other. The magnetic locking unit comprises a magnet control and at least a magnet. The magnet is arranged at one of the first element and the second element. The magnet control is configured to control a magnetic force between the first element and the second element.

Abstract: To reduce energy losses for a welding device when on stand-by and to enable a clean and controlled start of the welding phase, a DC-to-DC converter of the welding device converts an input DC voltage present at an input connection to an output DC voltage present at an output connection. At least one switch element of a branch of the DC-to-DC converter is switched with a switching frequency, and a welding phase is provided for the welding device, during which the switching frequency corresponds to a normal switching frequency.

Abstract: A method for controlling a power source is specified. The power source comprises a first converter (1) for converting an input voltage (UE) to an intermediate circuit voltage (UZK, UZK1), an intermediate circuit capacitor (2) and a second converter (3) for converting the intermediate circuit voltage (UZK, UZK1) to an output voltage (UA). A process is being controlled at the output of the second converter (3). A digital process controller predetermines at least one parameter and/or the value thereof to control the intermediate circuit voltage (UZK, UZK1) for the first converter (1) depending on an event at the output.

Abstract: The invention relates to a remote controller for a welding device (1) with a housing, a control unit (33) and several contact elements (27), wherein one contact element (27) is comprised of a workpiece contact (30) for establishing a connection with a workpiece (16), and wherein at least two further contact elements are comprised of electrode contacts (28, 32) for establishing a connection with an electrode (13) of the welding device (1), wherein the one electrode contact (28, 32) is designed for increasing the value of a welding parameter and the second electrode contact (28) is designed for reducing the same, the value of the welding parameter thus being changeable by contacting the electrode contacts (28, 32) with the electrode (13) of the welding device.

Abstract: Generating a target image having a target palette from a source image. In general, in one aspect, a technique for generating from a source image a target image comprising target pixels having colors limited to colors found in a target palette includes: determining a source color of a region of the source image corresponding to a location of a target pixel; generating two or more candidate colors for the source color, where the candidate colors are in the target palette; selecting one candidate color from the two or more candidate colors; and setting a target color of the target pixel to be the selected candidate color.

Abstract: A carrier assembly connects a memory storage device with electrical equipment having a slide. The carrier assembly includes a carrier adapted for holding a memory storage device and a folding handle. The folding handle has two arms which normally extend from the carrier. Each arm has an end rotatably attached to the carrier. Each end has a cam member, a biasing member and a locking member. The handle normally stands in an upright position with respect to the carrier, but can rotate to a folded position. The cam member is attached to the end of each arm to urge against the slide to move the carrier with respect to the slide and electrically connect the memory storage device with the electrical equipment when the handle is in the folded position. The locking member attaches to each cam member and engages with the side of the carrier to lock the handle when the handle is in the folded position.

Abstract: Disclosed herein is a bracket assembly for installing and removing an electrical device into and out of electrical equipment. The bracket assembly includes a slide and a mating carrier. The slide is semi-permanently mounted in electrical equipment, such as a computer work station or a shoe box or a personal computer. A compatible carrier includes the electrical device mounted thereon and engages and mates with the semi-permanently mounted slide. The slide is electrically connected to the electrical equipment and the carrier is electrically connected to the slide. In addition to being physically connected to the electrical device, the carrier is electrically connected to the electrical device by means of an electrical interconnect. Additionally, the carrier includes a configuration identification switch which allows the user to assign a device identification number while the electrical device is mounted on the carrier. The device identification number is visible to the user.

Abstract: The method of displaying multitone images beginning with a grayscale original image capable of displaying a specific number of gray levels, which includes the steps of: (1) selecting a plurality of colors from the image, one for each of the multitones, each having a color value; (2) selecting a plurality of transfer functions, one for each of the selected colors; (3) converting each of the shades of gray, using the respective color values and the transfer functions, into a new color value; and (4) displaying the resultant multitone image on a video display terminal using the new color values in place of the shades of gray. The displayed image may be printed using one printing plate for each of the selected colors, and using the same transfer functions to convert the shades of gray to new gray values which are subsequently converted into halftone dots for each printing plate.
