Abstract: Presented herein are techniques for estimating skin flap thickness (“SFT”) of a recipient of an implantable medical device system. In particular, in accordance with the techniques presented herein, the implantable medical device comprises an external component having a magnet configured to magnetically couple the external component to an implantable component of the implantable medical device system through a skin flap of a recipient of the implantable medical device system. The SFT is estimated based on a strength of the magnet. One or more operational parameters for the implantable medical device system may be determined and/or set based on the estimated SFT.

Abstract: Examples disclosed herein are relevant to testing capacitors to identify potentially faulty DC blocking capacitors in implantable stimulators. In an example, the test includes selecting an active electrode, a return electrode, and a reference electrode. Short duration monophasic stimulation is used to charge up the DC blocking capacitors of the active and return electrodes. The electrodes are subsequently disconnected from all other nodes except a discharge circuit (e.g., a star circuit) and the tissue. The reference electrode is used to measure the voltage of the DC blocking capacitor of the active electrode during the charging phase and the discharging phase (via the discharge circuit). The characteristics of one or more of the capacitors charging or discharging can be sensed and then analyzed to determine whether the one or more capacitors are functioning properly. Faulty capacitors can be identified by comparing actual and expected characteristics.

Abstract: The present invention concerns a method for recovering phosphorus by thermochemical reaction of a phosphorus-containing material such as an alternative fuel, for example, in the presence of calcium-containing particles in a moving bed reactor and subsequent separation of fines enriched with phosphorus from the moving bed reactor. Furthermore, the present invention concerns the use of a recyclable material obtained by the method as a fertilizer or fertilizer additive.

Abstract: Presented herein are techniques for electronically locking an electronic device in response to detection of a safety critical fault. As used herein, a “safety critical fault” is a fault having a potential to cause harm to an individual using the device. In particular, an electronic device in accordance with certain embodiments presented herein is configured to determine when the electronic device has experienced a safety critical fault. In response, the electronic device automatically restarts itself and, following restart, is automatically forced into a locked mode. The locked mode prevents execution of a run-time program stored in the electronic device.

Abstract: A method, wherein the method includes obtaining data, wherein, the data contains audio content, visual content, or audio content and visual content processing data based on the audio and/or visual content using results from machine learning to develop output, and stimulating tissue of a recipient to evoke a sensory percept based on the output.

Abstract: An improved arrangement for detecting DC current leakage in implanted devices is disclosed. Currents are monitored, so that any unexpected imbalance indicates that a fault condition has occurred. The principle of the system is that if everything working correctly, the same current should be flowing into the tissue from VDDH-ELEC as is passing out of the tissue into VSS_ELEC. Any difference is indicative of current flowing into or out of the tissue from unknown paths, which is indicative of some fault. This replaces routine monitoring for specific faults.

Abstract: A method and device for measuring an evoked neural response comprising a sensor (25) for obtaining a sensed signal representing the evoked neural response, a high gain amplifier (30) having a signal input (31) for receiving the sensed signal and having a reference input (32), and means for altering or setting a reference voltage at the reference input (32) to prevent the amplifier (30) saturating with variations of the sensed signal.

Abstract: The invention relates to a method for easily and rapidly preemphasizing an optical multiplex signal transmitted by an emitter to a receiver consisting wherein signal-to-noise ratios are equalized by means of simple measurement or new adjustment of signal power on the bandwidth of the optical multiplex signal, at least in the receiver, instead of measuring the noise output power or the signal-to-noise ratio. Said invention is based on a balance of the signal-to-noise ratios which are authorized by a transmitting system, in which the spectral influences of gain profiles, noise effects and dampings are taken into consideration. In particular, when DWDM transmission techniques are applied, in which adjacent channel spacings of the optical multiplex signal are very low, the inventive method makes it possible to use a small number of sensitive and high-resolution measuring instruments for pre-emphasis control.

Abstract: According to the invention, in add-drop devices of an optical cross-connect device for wavelength multiplex signals, tributary drop signals to be dropped are pre-selected in the drop branch by means of pre-selection elements. Only these signals are amplified, thus reducing the number and/or power of the optical amplifiers. The tributary drop signals are individually selected by means of drop routing elements and adjustable filters. The add branch is created correspondingly.
