Systems and methods for interactive mobile fitting of hearing aids are provided. The method includes a mobile device receiving a reduced size fitting data set having a set of sampling points from a hearing aid. The method includes interpolating the reduced size fitting data set into a continuous fitting curve presented at a display of the mobile device with user interface objects that each correspond with one or more sampling points. The method includes receiving a user input manipulating a user interface object. The user input adjusts a value of sampling point(s) corresponding to the user interface object to generate an updated reduced size fitting data set that is communicated to the hearing aid. The method includes generating a substitute complete fitting data set based on the updated reduced size fitting data set for application to input audio to generate modified audio that is output from the hearing aid.

A liquid container tilting apparatus designed for household and commercial use; made from a resilient material, capable of automatically tilting to a maximum tilt angle to optimize the draining of the last 1-6 cups of liquid from the container. As the liquid from the container drains, the tilting angle increases. The tilting apparatus is made of a base, a platform lever and a basket. The platform lever is part of the base. The basket holds the liquid container securely to the platform lever. The liquid container tilting apparatus can be cleaned and stored inside the liquid container or hung.

An apparatus and method for collecting drips from a spout on a beverage dispenser has a table top base that is held in place by the weight of a beverage dispenser. The table top base supports a drip catch reservoir, and drips hit a back plate with guides before washing into the drip catch reservoir. The drip catch reservoir has an outlet allowing drainage into a disposal tank without moving the apparatus.

A reusable metal casket is configured to receive a tray supporting the deceased. The casket includes a base, having a head end, a first side, a second side, and a foot end, and a lid. The lid is rotatably coupled to the first side or the second side. The foot end is rotatable relative to a bottom of the casket to enable insertion and removal of the tray. The head end and the foot end include curved corners. Accordingly, the interfaces between the head end and the foot end and the first side and the second side are formed separately from the curved corners.

The present invention provides a switch method and apparatus that is switchable among a plurality of operational modes by attenuating an input audio signal detected by the apparatus. The apparatus includes a microphone which converts the input audio signal to an input electrical signal (IES), a first memory which stores a threshold value, a second memory which stores at least one parameter set, a selector which is responsive to the first memory and to the IES for selecting a first parameter set as an enabled parameter set, and a signal conditioner coupled to the IES, the signal conditioner being responsive to the IES and to an enabled parameter set for producing a conditioned electrical signal (CES). An alternative switch method and apparatus switchable among a plurality of operational modes by attenuating an input audio signal detected by the apparatus includes a microphone which converts the input audio signal to an IES, a signal envelope detector (SED) coupled to the IES, the SED having a first time constant, wherein the SED produces a SED output in response to the IES, a noise envelope detector (NED) coupled to the IES, the NED having a second time constant that is greater than the first time constant, the NED produces a NED output in response to the IES, a first memory which stores at least one parameter set, a selector which is responsive to the SED output and to the NED output for selecting a first parameter set as an enabled parameter set, and a signal conditioner coupled to the IES, the signal conditioner being responsive to the IES and to an enabled parameter set for producing a CES.

A method and an apparatus for minimizing latency in digital signal processing paths. One example is an active noise cancellation device. The system includes a digital closed feedback loop having a forward path and a feedback path. The forward path includes a compensation filter, a digital-to-analog converter, and an output transducer. The feedback path includes an input transducer, a feedback delta-sigma modulator, and a feedback sampling-rate converter. An input signal is processed in one of several ways into a processed digital input signal having a preselected intermediate sampling rate. Through the feedback path, an analog output signal is processed into a digital feedback signal having substantially the same preselected intermediate sampling rate. The processed digital input signal and the digital feedback signal are combined and processed through the forward path to produce an anti disturbance signal that is combined with a disturbance signal to form the analog output signal.

A method for fitting a hearing compensation device comprises selecting a plurality of loudness levels for a plurality of frequencies and comparing each loudness level for each frequency for perceived sameness. The loudness levels may then be adjusted as needed to achieve perceived sameness across the frequency spectrum. A gain curve for each frequency is calculated from the selected plurality of loudness levels.

A golf swing training apparatus including a waist belt to be worn about the girth of the user having a downwardly depending leg strap with one end adjustably attached to the waist belt while the opposite end terminates in a pair of retaining straps. The leg strap is trained between the legs of the user so that a flexible resilient member extends about the leg intended to be immobilized while the restraining straps extend across the front of the user and releasably extend above and below the opposite knee. The retaining straps are arranged in fixed spaced-apart relationship so that the knee comfortably is positioned between the straps. Swinging movement by the upper torso of the user is permitted in a normal way; however, the knee having the resilient member extended thereabout is immobilized since one end of the leg strap is secured to the waist belt while the other end of the leg strap is releasably attached to the opposite leg.
