Abstract: A method for synchronizing time in an Ethernet-based network having a master network subscriber and a slave network subscriber includes sending out a first telegram via the master network subscriber, where the slave subscriber receives the first telegram at a first receipt time value of a local system time and stores the first receipt time value. The method can also include reading out the first receipt time value via the master subscriber, sending out a second telegram by the master subscriber, where the slave subscriber receives the second telegram at a second receipt time value of the local system time and stores the second receipt time value, and reading out the second receipt time value via the master network subscriber. A speed parameter of the local system time can be calculated from the receipt time values via the master network subscriber, and transmitted to the slave subscriber.

Abstract: The present invention relates to a lightweight composite architectural panel assembly, comprising: a) at least a first and a second end joist spaced parallelly along a perimeter of the assembly, each having a length; b) at least one web plate spaced parallelly between the end joists; an upper surface arranged in parallel to a lower surface; and attached to the at least first and a second end joist and the web plate, forming one or more channels disposed vertically between the upper and lower surfaces and longitudinally extending along the upper and lower surfaces, thereby forming an open-ended boxlike body; and c) a structural vertically load-bearing sheathing layer enveloping and adherent to the outer surface of the open-ended boxlike body, wherein the sheathing layer comprises a composite skin comprising a fibre mesh and a crosslinked polymeric resin system.

Abstract: The present invention relates to a color display device comprising a color display tube (1) with a front portion having a truncated cone (3), an element (5) for generating a plurality of electron beams, a shielding (9) of ferromagnetic material extending substantially parallel to the truncated cone (3), and a demagnetizing device having at least two demagnetizing coils (11,12) extending along the outer circumference of the cone (3). The demagnetizing device is arranged to energize the coils (11,12) simultaneously and with a phase difference, resulting in the generation of a rotating magnetic field. As the magnetic field rotates, it can be arranged to substantially coincide with the shape of the shielding (9), resulting in a magnetic field that is parallel to the shielding (9) over a larger part of the shielding surface. This improves the demagnetizing procedure, leading to a better landing performance of the electron beams.
