The invention relates to a scaffold with vertical supports arranged spaced apart next to one another and/or behind one another, with horizontal carriers arranged between adjacent vertical supports and with scaffold decks which releasably lie at their end regions on oppositely disposed horizontal carriers another and preferably extending parallel to one another, preferably by means of hooks,. The invention consists of the fact that the scaffold decks have at least one laterally projecting guide s...

The invention relates to a method for monitoring at least one measuring signal, in particular for use in automation technology, production automation and process automation. Said method automatically determines and establishes an optimal time interval between measuring periods, by means of the course of a measuring signal. According to the invention, a computer system cyclically determines a characteristic value of the measuring signal in measuring periods, which are separated by a time interval...

A calendar for an electronic device includes suitable programming so that the calendar is displayed on two or more electronic devices, such as computers. Programming of the calendar is operable so that when someone at one of the electronic devices alters a calendar item, an animation corresponding to such alteration is displayed on the calendar displayed at another one of the electronic devices.

An electronic timepiece has an operating unit for switching between a time display mode and a demo display mode, a time measuring unit for measuring time, and a storing unit for storing a timing condition for switching between the time display mode and the demo display mode. A control unit outputs a time display signal representing time measured by the time measuring unit when the operating unit switches to the time display mode, outputs a demo display signal when the operating unit switches to ...

The control method allows execution of various functions in an electronic diary watch, which includes, in a case closed by a crystal, a time-keeping circuit and/or a watch movement powered by an energy source, and a dial on which the time is displayed in a digital and/or analogue manner. A determined number of sensors (C1 to C7) are provided with touch sensitive pads arranged on an inner or outer face of the crystal. These sensors are provided for carrying out the various controls of the method ...

The present invention provides a method for synchronizing timekeeping devices in a system of clocks using a master/slave system and expandable data packet transmission protocol, and an apparatus for implementing such synchronizing system. The method includes embedding a circuit and data packet for transmission into each timekeeping device in the system. Time is synchronized by transmitting time information contained in the data packet protocol from the master timekeeping device to other slave ti...

A method and device that controls one or more apparatus in relation to the expected time of sunrise and sunset at the location of the apparatus. The operator enters a geographic location identifier, such as a zip code or telephone area code, and the controller computes the expected time of sunrise and sunset at the corresponding geographic location. The controller is configured to translate the entered geographic location code into the offset times, based upon the latitude and longitude of the l...

A clock circuit for driving a clock movement such as a bipolar clock contains a memory which is programmed to automatically adjust the clock movement for standard and daylight saving time adjustments. The circuit is normally powered from the AC power line but includes a battery backup and is designed to run the clock circuit uninterruptedly for its entire life without needing used initiated adjusting or actuating.

A variable color optical device comprises three light emitting diodes for emitting upon activation light signals of respectively different primary colors and means for blending the light signals to obtain a composite light signal of a composite color. The light emitting diodes are substantially simulteneously activated by pulses of a substantially constant amplitude. Color control selectively controls the durations of the pulses to control the portions of the primary colors, to thereby control t...

Centrifuging apparatus having a light source shining through the samples being centrifuged is modified by providing a flash tube which flashes in synchronism with passage of the sample over a photoelectric pickup. The flash tube is controlled from a capacitive transducer, so that optical and inductive errors are avoided. More than one flash tube may be used, each flashed for a specific sample, and supplied with monochromators adjusted for maximum, or minimum absorption wave length.
