  • Patent number: 11122356
    Abstract: An animal headphone assembly for soothing a canine when the canine is exposed to distressing sounds includes a pair of headphones. Each of the headphones has a diameter sufficient to cover ears of a canine for wearing over each of a canine's ears. A plurality of straps is each coupled between each of the headphones to extend around the canine's head for retaining the headphones over the canine's ears. A sound unit is integrated into the headphones to emit sound outwardly therefrom. The sound unit stores a database comprising a plurality of musical songs to emit pleasing sounds into the canine's ears. Each of the musical songs includes concealed binaural beats to soothe the canine.

  • Patent number: 10648133
    Abstract: Methods of reducing paper dusting in a papermaking process, and a low dusting tissue having increased strength are provided. Application of a polymer comprising at least one amine-containing vinylic or allylic monomer to at least one surface of a paper web during the papermaking process reduces the dusting tendency of the paper, and increases both the wet and dry strength of the paper product.

  • Patent number: 10575075
    Abstract: Various examples are provided for digital sound reconstruction using piezoelectric array elements. In one example, a digital loudspeaker includes a fixed frame and an array of transducers disposed on the fixed frame. Individual transducers of the array of transducers can include a flexible membrane disposed on a piezoelectric actuation element positioned over a corresponding opening that extends through the fixed frame. In another example, a method includes forming a flexible membrane structure on a substrate and backetching the substrate opposite the flexible membrane structure. The flexible membrane structure can be formed by disposing a first electrode layer on a substrate, disposing a piezoelectric layer on the first electrode layer and disposing a second electrode layer on the piezoelectric layer. A flexible membrane layer (e.g., polyimide) can be disposed on the second electrode layer.

  • Patent number: 10070722
    Abstract: A sliding storage compartment assembly for a motor vehicle includes a storage bin slidably received in a storage bin holder by a dual track assembly defined by opposed sets of rails and opposed sets of cooperating tracks. Each of the opposed sets of rails and opposed sets of cooperating tracks are vertically and laterally offset one from another. Each of the opposed sets of rails and each of the opposed sets of cooperating tracks may be vertically offset one from another in a vehicle z-axis direction and laterally offset from one another in a vehicle x-axis direction. The opposed sets of cooperating tracks may be disposed on opposed side walls of the storage bin holder and the opposed sets of rails may be disposed on opposed side walls of the storage bin, or vice-versa. Console assemblies including the sliding storage compartment assembly are described.

  • Patent number: 9764790
    Abstract: A transportation device includes a frame foldable between a bicycle configuration and a personal transporter configuration. A sensor configured to sense when the frame is in at least one of the bicycle configuration and the personal transporter configuration. A first wheel and a second wheel are each rotatably coupled to the frame. A first motor is coupled to the first wheel and a second motor is coupled to the second wheel. A controller is programmed to instruct the first motor to rotate in a first direction in response to a signal from the sensor that the frame is in the bicycle configuration, and to instruct the first motor to rotate in a second direction opposite the first direction in response to a signal from the sensor that the frame is in the personal transporter configuration.
