Abstract: Methods and systems consistent with the present invention provide an improved system that supervises the operation of a backup amplifier. The method comprises receiving an indication that a primary amplifier failed; determining a configuration of the primary amplifier; and configuring the backup amplifier to match the configuration of the primary amplifier.

Abstract: An approach for supervision of an audio path within an audio system that conserves power while operating in battery mode by temporarily turning off pre-determined audio components of the audio system when not performing supervision tasks and no audio is present on the audio path.

Abstract: A separating device for an energy-conducting electric lead includes a monitoring unit for checking the electric properties of a lead section of the lead adjacent to the separating device, an energy storage device that is coupled to the monitoring unit such that the function of the monitoring unit can also be maintained in case of a failure of the lead, and a switching element, which is coupled to the monitoring unit and which is equipped such that in case of a failure of the lead the adjacent lead section can be separated. The disclosure further relates to an energy supply system and to a method for providing electric energy from a control center to a plurality of electric devices via an energy-conducting electric lead having at least one such separating device.

Abstract: A limit indicator technology based detector line of a fire detection system has a line current applied to it during operation and has a final element formed by a TVS diode. At least one of the line current and the line voltage are monitored. Faults of the detector line are detected by a brief increase and a brief reduction in the line current.

Abstract: The invention relates to a disc-shaped counter, in particular a casino chip, essentially consisting of at least one ring-shaped plastic part and a filler piece held inside a recess in this plastic part, which is applied on to the filler piece in such a way that the plastic ring surrounds the rim of the filler piece radially and axially in an at least partly form-fitting fashion. The filler piece and/or plastic ring contain a material that is detectable in slot-machines. The plastic ring is preferably applied on to the filler piece by a plastic injection moulding process. The counter according to the invention has a more attractive design, is considerably easier and cheaper to produce, and has greater durability, than conventional counters with inserts.

Abstract: The invention concerns a disc-like plastic body with inlay portion, essentially consisting of at least one composite filler body holding the inlay portion between itself. A visually pleasing plastic body which is easy and cheap to make is provided according to the invention by the fact that the filler body is encompassed by two lid-like films, one film after the fashion of a cup surrounding the filler body on one side and the other, opposite film after the fashion of a lid being applied to the opposite side of the filler body.
