  • Patent number: 11589147
    Abstract: Systems, methods, and computer-readable media are disclosed for display devices with transverse planar microphone arrays. In one embodiment, an example voice-activated device may include a housing, and a display assembly coupled to the housing, where a first vertical axis associated with the display assembly is at an acute angle relative to a second vertical axis associated with the housing. Example devices may include a number of microphone openings disposed in a front face of the display assembly, a speaker coupled to the housing and oriented to direct a portion of sound towards a rear portion of the device, and a fabric disposed over the housing, the fabric comprising an aperture disposed along the rear portion of the device.

  • Patent number: 10462545
    Abstract: Voice activated electronic devices are described herein. In some embodiments, the voice activated electronic device may include a housing forming a cavity. An array of microphones, one or more speakers, and one or more cameras may be located within the cavity. Furthermore, the voice activated electronic device may include a display screen and a touch screen, which may both be coupled to the housing such that the housing is substantially enclosed. In some embodiments, the array of microphones is positioned about the housing such that audio input may be detectable from audio output by the speaker(s) while the speaker(s) are outputting audio. For instance, one or more vibration mitigators may be included to dampen vibrations that may affect a performance and functionality of the one or more components located within the cavity.

  • Patent number: 8701220
    Abstract: A jet powered toilet flushing system, including: a toilet bowl; a reservoir; a fluid conduit between the reservoir and the toilet bowl; a jet inside the reservoir, the jet having a nozzle directed toward an entrance of the fluid conduit; a fill valve that supplies water to the jet; and a flow diverter in the reservoir, the flow diverter positioned to divert water flow: (a) from the jet nozzle into the entrance of the fluid conduit when the reservoir is full, or (b) from the jet nozzle away from the entrance of the fluid conduit and into the reservoir when the reservoir is empty.

  • Publication number: 20120000858
    Abstract: A computer based method for generating a pulsating water flow through a faucet in response to a filter status, comprising the steps of: determining a water flow rate through a first filter; determining a duration of water flow at said water flow rate; determining the filtered volume of water filtered by said first filter based upon said water flow rate and duration of water flow; determining the filter status by comparing said filtered volume of water and an expected rated service life value of said first filter; and causing the faucet to expel pulsating water when the faucet is in the on state, when the filter status represents that remaining filter life is below a first threshold.

  • Publication number: 20120004778
    Abstract: A system and method for preventing damage and undesirable situations/conditions from occurring in point of use (POU) or point of entry (POE) water systems that are not in regular use. This invention may be implemented in residential, non-residential situations or constructions where it can add value, such as commercial properties that undergo seasonal and/or other periods of disuse. In cold climate areas, faucets should be turned on and run to prevent water in the pipes from freezing, which can cause pipes to burst or leak and result in significant property damage. In all climates rust, corrosion, particles, contamination, and biofilm, can develop and/or settle in the pipes if faucets are not turned on periodically, resulting in sub-standard water quality when the system is eventually used. Also, if water is left to sit in residential pipes, other effects/conditions can take place over time that generally effect color, taste and order of the water if it does not periodically move through the system.
