Abstract: Systems, methods, and devices for recording, sharing, and storing an audio segment are provided. A user's audio segment is recorded by a recording device, in response to an audible prompt generated by the recording device. In some embodiments, the recording device provides a signal to the user that a recording session is in progress. Having recorded the audio segment, the recording device provides a reply to the user's recording, simulating a conversation between the recording device and the user. In embodiments, the recording device transfers the recorded audio to a sharing device for playback of the recorded audio segment. Further, the recorded audio segment may be transferred to a storage device, for storage and retrieval of the audio segment at a later date. The components of the recording device may be housed inside a commercial embodiment, such as a stuffed toy, for concealed recording of the user's audio segment.

Abstract: A pump housing has a spiral housing and includes a suction channel (14) which runs out in a space (15). The space (15) is for arranging an impeller (6), rotatable about a rotation axis (5), and includes a spirally peripheral channel (16) open to the space (15) and running out into a pressure channel. A receiver (20) for a differential pressure sensor is provided within the pump housing. A first sensor channel (22) is provided, which connects the receiver (20) to a pressure-side interior of the pump housing. A second sensor channel (23) connects the receiver (20) to the pressure-side interior of the pump housing. The receiver (20) for the differential pressure sensor is arranged between the spirally peripheral channel (16) and the suction channel (14), so that the channels can be formed by way of simple bores.

Abstract: Aspects of the present invention enable a storage device (e.g., a recordable book, toy, computing device) to be controlled with a single control button that performs multiple functions. Different interactions with the button produce a different control input. In one aspect, the storage device is an audio recording device that can record, lock, unlock, transfer to a separate storage device, or play back one or more audio recordings. These five functions (i.e., recording, locking, unlocking, transferring, and playing back) are initiated or facilitated by depressing a single button located on the audio storage device for different lengths of time or in different patterns. Audio recordings may be played in response to user interactions with the button to help the user interact with the button properly and warn the user of action that is about to be taken.

Abstract: A modular display frame and system for hanging a plurality of modular display frames is provided. In embodiments, a modular display frame may be magnetically coupled to other modular display frames as well as a hanging bar component to create a plurality of display iterations. Each modular display frame includes two portions, each portion partially housing at least one magnet within a corner-located pocket, in embodiments. The modular display frame further includes a rounded side for creating a range of display angles when magnetically coupled to another frame along the rounded side, as well as a flat side for facilitating upright displays and vertically stacking magnetically coupled display frames, in further embodiments. A hidden hanging feature with auto-centering ability enables the modular frame to be hung on a wall, for example.

Abstract: Embodiments of the present invention use one or more audible tones to communicate metadata during a transfer of an audio file. Embodiments of the present invention communicate an audio file from a speaker in a recording device (e.g., a recordable book, toy, computing device) to a microphone in a receiving device. The audio file is transferred by audibly broadcasting the audio file content. The audio file may be a recording made by the user (e.g., the user singing a song, a child responding to a storybook prompt intended to elicit a response). The file transfer process uses one or more audible tones, such as dual-tone multi-frequency signaling (“DTMF”) tones to communicate metadata associated with the audio file. Audible tones may also be used to communicate commands that delineate the beginning and/or end of a file broadcast.

Abstract: Methods and devices for storing and associating audio tracks to user-defined touch zones on a photo frame are provided. In one aspect, the photo frame includes a capacitive sensor array that provides a platform for a user to overlie a photo thereon. The capacitive sensor is coupled to a microprocessor that permits the generation of user-defined touch zones based on the user selecting an object in the photo by encircling the object with a touch gesture. The frame also includes a microphone for recording an audio track corresponding to each user-defined touch zone. The audio tracks and corresponding touch zones are stored in a memory. In some embodiments, the microprocessor can determine a selected touch zone based on a location of the user's touch and, based on the location, playback the audio track corresponding to the selected touch zone.
