摘要:
An apparatus is described for fixing floating bodies (1), in particular boats, to a landing body (2) with at least two holding booms (5) which are fixed to respective moorrings (4) by fittings (3) functioning as coupling elements, in each case at one end on the floating body (1) and at the other end on the landing body (2). In order to create advantageous conditions, it is proposed that at least one of the holding booms (5) be fixed, at least at one end, to the respective moorrings by the fitting (3) functioning as a coupling element so as to be rotationally fixed or rotationally resilient about an at least approximately vertical axis (7) with an adjustable and fixable angular offset (α).

A method and apparatus for carrying an ATM communication protocol on a hybrid fiber coax CATV system. Point to point communication is supported by use of synchronous code division multiplexing on the physical and by assigning on the MAC layer one or more orthogonal SCDMA codes exclusively for use by pairs of devices needing to communicate such the head end and any customer premises equipment. Quality of service or guaranteed bandwidth availability is implemented by controlling the code space at the MAC layer such that certain CPEs having in use peripherals which cannot tolerate interruptions in data flow may reserve one or more SCDMA codes for use exclusively by them. Standard ATM cells are modified by the addition of a two byte virtual link header which identifies to which CPE a particular ATM packet is destined. This virtual header also makes possible broadcast and multicast of packets from the head end to all CPEs. Each byte in each ATM cell has 8 bits of data and a 9th bit which is encoded with to indicate where the ATM cell starts and includes CRC data for error detection and correction. Bandwidth is allocated by the head end computer which executes algorithms on the MAC layer to collect actual bandwidth usage information and requests for bandwidth and prioritize them in accordance with the channel allocation/reservation scheme currently use. The channel allocation/reservation scheme can be changed on the fly and reallocation calculations to adjust bandwidth allocations are calculated every 10 milliseconds and the new allocations are distributed in downstream messages which are transmitted to all CPEs.

A frame element of an installation facility is fastened to a mounting plate of an electrical installation by a fastening element having at least two holding elements, arranged adjacent to one another in a shared plane, that can be elastically deformed relative to one another and each including at least one limb. The limbs are embodied such that they face one another along an imaginary straight line within the shared plane and include a segment of minimal spacing along the imaginary straight line. The spacings of the limbs from one another increase in all other segments along the imaginary line from the segment of minimal spacing.

An apparatus is described for fixing floating bodies (1), in particular boats, to a landing body (2) with at least two holding booms (5) which are fixed to respective mooring means (4) by means of fittings (3) functioning as coupling elements, in each case at one end on the floating body (1) and at the other end on the landing body (2). In order to create advantageous conditions, it is proposed that at least one of the holding booms (5) be fixed, at least at one end, to the respective mooring means by the fitting (3) functioning as a coupling element so as to be rotationally fixed or rotationally resilient about an at least approximately vertical axis (7) with an adjustable and fixable angular offset (α).

Setting information relating to mechanical settings of a digital x-ray imaging system, settings of a control variable or settings of an image processing system, as had been performed during the recording of the relevant digital x-ray image, are stored for a digital x-ray image. It is thereby made possible for an operator to read out the setting information and restore the x-ray image recording situation. The setting conditions can even be restored automatically. This also applies to at least the major part of the mechanical settings.

There is described a radiography device for recording dynamic processes and an associated recording method. The radiography arrangement is used to examine patients using an x-ray source, a digital flat detector with a single shot recording function and an operating console for controlling and recording purposes, with the flat detector also being able to display an image sequence at a rate of up to 5 Hertz, which allows the positioning of the region to be examined or the monitoring of pseudo-interventional interventions.
