Abstract: Methods and apparatus provide digital media with spatial audio to a blockchain. The blockchain network executes a decentralized application (Dapp) with a user interface (UI) that enables a user to select audio for spatialization and uploading to the blockchain. The spatial audio transmits to the blockchain network to reduce processing and transmission of network data.

Abstract: A method or apparatus provides binaural sound that originates to a person at a location inside a field of view (FOV) provided to the person by an electronic device. The electronic device determines when the location of the binaural sound moves outside the FOV and assists the person in determining the location of the binaural sound. A display of the electronic device displays a visual indication that shows a direction to the location of the binaural sound outside the FOV.

Abstract: A method expedites processing and playing of binaural sound during an electronic communication between a first user and a second user. An electronic device of the first user convolves sound into binaural sound for the second user before the binaural sound transmits to the electronic device of the second user. In this way, the binaural sound is already convolved and ready to play upon receipt at the electronic device of the second user.

Abstract: A method plays sound clips in binaural sound to users during an electronic communication between two or more users. A processor convolves the sound clips with HRTFs so the sound externally localize away from a head of the user listening to the sound clip. The sound clips play to users during the electronic communication without transmitting the sound clips to electronic devices of the users.

Abstract: A method provides binaural sound to a listener while the listener watches a movie so sounds from the movie localize to a location of a character in the movie. Sound is convolved with head related transfer functions (HRTFs) of the listener, and the convolved sound is provided to the listener who wears a wearable electronic device.

Abstract: In one aspect, a dialysis fluid cassette includes an inlet fluid line, multiple outlet fluid lines, and a valve including an actuation feature by which the valve can be rotated to fluidly communicate the inlet fluid line with a selected fluid line of the multiple outlet fluid lines.

Abstract: A method improves performance of a computer that provides binaural sound to a listener. A memory stores coordinate locations that follow a path of how the head of the listener moves. This path is retrieved in anticipation of subsequent head movements of the listener to improve computer performance of executing binaural sound.

Abstract: A firearm system includes a firearm and a computer. Electronics in the firearm determine data that includes a pathway between different points of aim of the firearm as the firearm moves. The computer receives this data and builds an image of the pathway between the different points of aim of the firearm.

Abstract: One or more electronic devices include one or more processors that process different segments or channels of an audio signal of sound for a user. The one or more processors process a first segment or channel of the sound with first HRTFs so the first segment or channel externally localizes in front of and to a right of a head of the user and process a second segment or channel of the sound with second HRTFs so the second segment or channel externally localizes in front of and to a left of the head of the user.

Abstract: In described examples, a spatial light modulator includes groups of pixels. Each group is arranged to transmit only a respective portion of a light spectrum. The respective portion has a respective dominant color. The respective portions of the light spectrum are distinct from one another, according to their respective dominant colors. Each group is controlled by a respective reset signal. The spatial light modulator is coupled to receive a selection from the integrated circuit and in response to the selection: cause a selected one of the groups to transmit its respective portion of the light spectrum; and cause an unselected one of the groups to block transmission of its respective portion of the light spectrum. A photodetector is coupled to: receive the respective portion of the light spectrum transmitted by the selected group; and output a signal indicating an intensity thereof.

Abstract: A home appliance can operate in a future time frame. Information is obtained from a power distributor in order to determine a time when to operate the home appliance in this future time frame. The home appliance then operates at the time determined with information from the power distributor.

Abstract: A method or apparatus switches between binaural sound and stereo sound in response to head movements of a listener. An electronic device provides the listener with binaural sound at a sound localization point (SLP) in a field-of-view of the listener. Binaural sound at the SLP switches to one of mono or stereo sound when head movements of the listener cause the SLP to move outside the field-of-view.

Abstract: A method provides binaural sound to a listener while the listener watches a movie so sounds from the movie localize to a location of a character in the movie. Sound is convolved with head related transfer functions (HRTFs) of the listener, and the convolved sound is provided to the listener who wears a wearable electronic device.

Abstract: Methods and apparatus improve a user experience during telephone calls or other forms of communication in which a listener localizes electronically generated binaural sounds. The sound is convolved or processed to a location that is behind or near a source of the sound so that the listener perceives the location of the sound as originating from the source of the sound.

Abstract: A smartphone displays an emoji that when activated plays sound that externally localizes in binaural sound to the listener. The emoji includes an indication that shows a location where the sound will externally localize as the binaural sound away from a head of the listener when the listener activates the emoji.

Abstract: A method processes binaural sound to externally localize to a first user at a first location. This location is shared such that an electronic device processes the binaural sound to externally localize to a second user at a second location. The first and second locations occur at a same or similar location such that the first and second users hear the binaural sound as originating from the same or similar location.
