Abstract: An optical space switch is used in a centralised switching system for an optical network and connects light from one of a number of inputs (1) to a selected one of a number of outputs (6). The switch includes a number of multiplexed phase volume holograms (4), a spatial light modulator (3) for imposing a selected phase change on light passing through it, distribution means (2) for coupling light from the inputs (1) via the spatial light modulator (3) to the multiplexed phase volume holograms (4), and collection means (5) for collecting light diffracted by the multiplexed phase volume holograms (4). Each multiplexed phase volume hologram (4) diffracts light to a selected output (6) in dependence upon the phase change imposed by the spatial light modulator (3) on the light incident upon that hologram (4).

Abstract: The invention relates to a method and to a device for comparing two ground-stationed clocks (1 and 2) that are linked with respective ground stations (2 and 4) via a satellite communications link (6.1 and 6.2). Both stations emit signals (S1 and S2) in coherence with their respective local clocks. Said signals are converted at the satellite (9) in a transponder (7) using the satellite-based local oscillator (8) and are returned to the ground. Each ground station receives the respective own signals (E 1-1 and E 2-2) and those of the counter-station (E 1-2 and E 2-1). For the purpose of measurement, the carrier phase ( phi  1-1,  phi  1-2,  phi  2-1,  phi  2-2) of the received signals is compared with the respective local clock and evaluated. The result of said evaluation are four independent measurements from which the unknown influences by the satellite-based local oscillator (8) and by the two different relative movements of the satellite with respect to the ground stations are eliminated. As a result, the frequency difference (5) of the clocks is determined.

Abstract: In a known device, an electrical contact is closed when an elastomer spring element associated with the drawbar coupling has sprung in to a prescribed extent or more under the action of the axial force. Upwards of the specific magnitude of the axial force, the device thus indicates only that such a force exists at all. This device is not suitable for applications in which the magnitude of the axial force is at issue. 
<??>In order to avoid this disadvantage, the invention proposes to measure the pressure produced by the axial force in the elastomer spring element and for this purpose to arrange a pressure sensor (2; 18 or 7) on a transfer shoulder (21 or 15; 20 or 17) between the elastomer spring element (5 or 16) and the housing (bearing parts 3 or 9) or the tension rod (6, 22) of the drawbar coupling. Alternatively, the pressure sensor (10) can be arranged on the elastomer spring element (5 or 16).
