Abstract: An exemplary system includes a processor communicatively coupled to a memory and configured to execute instructions to generate a modified audiogram for a user of a hearing device. The modified audiogram may be based on a frequency lowering scheme that maps at least some audio frequencies included in a first set of audio frequencies to relatively lower audio frequencies to form a second set of audio frequencies. The modified audiogram may indicate a set of modified hearing thresholds of the user at the first set of audio frequencies. The generating of the modified audiogram may include applying an inverse of the frequency lowering scheme to the set of modified hearing thresholds at the second set of audio frequencies to obtain the set of modified hearing thresholds of the modified audiogram at the first set of audio frequencies.

Abstract: A method of treating a mixture of microorganisms containing phosphorus and magnesium, by first inducing the mixture microorganisms to release phosphorus and magnesium. Next an emancipation or elutriation is performed. Phosphorus and magnesium-rich liquid is then tapped off as the mixture is thickened, to produce phosphorus and magnesium-rich liquid and phosphorus and magnesium-reduced treated mixture. This treated mixture is placed in an anaerobic digester where ammonia is formed but combines very little with phosphorus or magnesium as these elements have been reduced in concentration. Then the high-ammonia mixture is dewatered, to produce an ammonia-rich liquid, which is combined with the phosphorus and magnesium-rich liquid. In one preferred example a useable struvite product is harvested from this combination. Additionally, the production of nuisance struvite in the anaerobic digester is reduced, in comparison with prior art waste treatment methods.

Abstract: A method for operating a hearing device for a user having tinnitus includes converting an acoustic input signal into a corresponding converted input signal, applying a transfer function to the converted input signal for generating a processed input signal, generating a stimulation signal depending on characteristics of a perceived disturbing internal signal resulting from a tinnitus perceived by a prospective user of the hearing device, limiting the stimulation signal by applying a predefined limiting scheme thereby generating a limited stimulation signal, superimposing the limited stimulation signal onto the processed signal thereby generating an output signal, and feeding the output signal to an output transducer for generating a hearing device output signal.

Therein, the first hearing device has been, by means of a first fitting system, individually adjusted to needs and preferences of a specific hearing device user. The method comprises the steps of a1) providing data (165) related to the first hearing device; a2) providing data (155) related to the first fitting system; d1?) adjusting the second hearing device in dependence of the data (165) related to said first hearing device and of the data (155) related to said first fitting system. The corresponding apparatus is disclosed, too. A fitting can be transferred from the first hearing device to the second hearing device.

Abstract: A method of treating a mixture of microorganisms with readily biodegradable carbon compounds (RBCs) in the form of one or more volatile fatty acids (VFAs), by first inducing the mixture microorganisms to release phosphorus and magnesium which is then tapped o as the mixture is thickened, to produce a phosphorus/magnesium-nch liquid and a phosphorus/magnesium-reduced treated mixture This treated mixture is placed in an anaerobic digester where ammonia is formed, but combines very little with phosphorus or magnesium Next the high-ammonia mixture is dewatered to produce an ammonia-rich liquid, which is combined with the phosphorus and magnesium-rich liquid and reacted to form struvite In one preferred embodiment, VFAs are formed in situ via an upstream unified fermentation and thickening (UFAT) process and added to the waste sidestream to strip phosphorus and magnesium found therein In another preferred embodiment a usable struvite product is harvested.

Abstract: A thermal barrier coating for an underlying metal substrate of articles that operate at, or are exposed to, high temperatures, as well as being exposed to environmental contaminant compositions. This coating comprises an optional inner layer nearest to the underlying metal substrate comprising a non-alumina ceramic thermal barrier coating material in an amount up to 100%, and an outer layer having an exposed surface and comprising at least about 50% of a non-alumina ceramic thermal barrier coating material and alumina in an amount up to about 50% and sufficient to protect the thermal barrier coating at least partially against environmental contaminants that become deposited on the exposed surface. This coating can be used to provide a thermally protected article having a metal substrate and optionally a bond coat layer adjacent to and overlaying the metal substrate.

Abstract: The invention facilitates individual selection and even field replacement of individual component-carrying contacts in a multicontact electrical connector. On a modular circuit-by-circuit basis, each circuit can be individually guarded against overvoltages, undesired frequencies, etc.; and in event of damage to a protection component, the protection can be easily renewed for any individual circuit in just a few minutes. An overvoltage-bypassing diode or other electrical component is positioned within a central cavity that extends axially within the body of a cylindrical contact--i.e., either a male pin or female receptacle. The component is oriented axially in the cavity. Because the bypassing component is physically protected within the cavity, it is much less vulnerable to physical and electrical damage in installation and service than in prior component-carrying contacts.

Abstract: To prevent possible misalignment of the various parts of a plug and receptacle connector, if the coupling ring is inadvertently rotated before the receptacle is in full position, there is provided an interlock sleeve. This sleeve is spring-loaded and positioned between the coupling ring and the plug outer surface. Internal and external keys incorporated within the sleeve prevent inadvertent rotation of the coupling ring until the receptacle has made entry into the plug sufficiently to key both the coupling ring and plug shell.

Abstract: To insure proper alignment of a plug and receptacle connector so that only a correct plug and receptacle are being mated, a set of similarly coded keyways and keys on the connector parts require respective alignment before mating is possible. More particularly, the coupling ring and enclosed plug shell both have a set of keyways (optionally, keys) which must be respectively aligned before the receptacle can be received within the plug shell. A spring biased pawl within a slotted cavity in the coupling ring has parts which upon correct orientation of the ring and plug extend into a recess in the plug shell effectively locking the two together and preventing inadvertent rotation of the coupling ring with respect to the plug shell when the connector parts are unmated. In this way the keyways on the inner surfaces of the coupling ring and plug shell are maintained in properly aligned relation so that they may receive the receptacle.

Abstract: The invention is directed to a protective cover for the open face of the receptacle section of a multi contact electrical connector when the receptacle section and the plug section are not mated. The protective cover comprises a barrel and a cover plate closing one end of the barrel. Inside the barrel there is positioned a spring means so located that a disc placed over the spring means can be controllably moved longitudinally in said barrel to contact the end of said receptacle open face. At the outer end of said barrel are indexing means for polarized alignment with indexing means on said receptacle and locking means, for locked retainment of said cover to said receptacle socket.

Abstract: The invention is directed to an electrical connector with multi-pin/socket contacts suitable for use in locations where the receptacle assembly is attached to a support, such as the underside of an aircraft wing, and the plug assembly is mounted on a separate detachable structure, such as a pylon. The plug assembly engages the receptacle through collet fingertips. A separate, but not independent, capsule assembly is mated with the receptacle socket contacts by vertical movement imparted by a cam assembly. The mated/engaged connector is locked in that relation by balls juxtaposed between a capsule assembly channel and a plug housing sleeve. The plug housing is suitably floated on spring loaded mounts attached to the pylon skin.
