Abstract: Methods and systems for managing inventory at a retail facility include an image capture device having a field of view that includes a product display shelf of the retail facility, an electronic database that stores a planogram of product display shelves at the retail facility and a computing device. The computing device obtains an image of a product display shelf, detects the individual packages of each of the different products captured in the image, defines different product display areas for the different products on the product display shelf captured in the image, and generates virtual boundary lines that surround each of the defined product display areas. The computing device also determines an identity of a product contained located in each defined product display area, and associates the virtual boundary lines surrounding each defined product display area with an identifier unique to the product contained in the defined product display area.

Abstract: Methods and systems for managing inventory at a retail facility include an image capture device having a field of view that includes a product display shelf of the retail facility, an electronic database that stores defined product display areas and assigned unique identifiers of the products on the product display shelves, and a computing device. The computing device obtains an image of a product display shelf, detects the individual packages of the different products captured in the image, identifies the products associated with the packages detected in the image by utilizing reference information stored in the database, determines whether one or more of the products on the product display shelf is associated with an out of stock event, and transmits an out of stock alert to an electronic device of a worker at the retail facility, notifying the worker to replenish the depleted products on the product display shelf.

Abstract: In a method of operating a hearing device, an input transducer of the hearing device generates an input signal. A preliminary output signal is generated from this input signal through signal processing. An expected direct sound that is expected to be heard at one ear of a user of the hearing device is ascertained based on the input signal. A propagation delay of the preliminary output signal is ascertained with respect to the expected direct sound. A masking signal is generated based on the input signal and/or the preliminary output signal, taking into account the expected direct sound and/or the propagation delay of the preliminary output signal with respect to the expected direct sound. An output signal is generated based on the preliminary output signal and masking signal.

Abstract: A method operates a hearing aid device, in particular a tinnitus treatment device. The hearing device has a microphone and a receiver, which can be inserted into an auditory canal of a user or is arranged at least in part in the auditory canal. Wherein active noise control of an acoustic environmental signal, which can be received by the microphone, is achieved at one or more tinnitus frequencies of a user by generating an acoustic cancellation signal from the receiver in the auditory canal of the user.

Abstract: A hearing system has a hearing instrument that may be worn in or on a user's ear, and a peripheral device or a control program that may run on a data processing device. A microphone signal detected by the hearing instrument is examined for the user's own-voice components and is processed by a signal processor of the hearing instrument as a function of predetermined signal processing parameters. When own-voice components are detected, a first parameter set of the signal processing parameters is applied; when own-voice components are not detected, a second parameter set of the signal processing parameters is applied. The first parameter set may be modified by the user via the peripheral device or the control program in order to adapt the own-voice components contained in the microphone signal to a user-desired perception of the user's own voice.

The catalyst composites have a two-metal layer on a carrier, the two-metal layer comprising a rhodium component supported by a first support comprising a refractory metal oxide component or a first ceria-zirconia composite; a palladium component supported by a second support comprising a second ceria-zirconia composite; one or more of a promoter, stabilizer, or binder; wherein the amount of the total of the first and second ceria-zirconia composites in the two-metal layer is equal to or greater than the amount of the refractory metal oxide component. Methods of making and using the same are also provided.
