  • Publication number: 20240091478
    Abstract: A mask system for delivery of respiratory therapy to a patient includes a nares portion and a mouth portion and an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas. The mask system is adapted to selectively utilize the nares portion and/or the mouth portion in a first mode utilizing both the nares portion and the mouth portion, and in a second mode utilizing the nares portion and not utilizing the mouth portion.

  • Patent number: 10549211
    Abstract: A bath book and a puppet combination and method of manufacturing a bath book and a puppet combination, wherein a first intermediate assembly is bonded to a second intermediate assembly to create a third intermediate assembly. A second jersey backing layer is secured to the third intermediate assembly to create a fourth intermediate assembly. The fourth intermediate assembly may be flipped inside-out through a hole opening in the second jersey backing layer. The hole may then be sealed. The second jersey backing layer may be pushed upwards into the further intermediate assembly. An adhesive film may be applied to the terry cloth ring and the non-woven material ring of the second intermediate assembly to create a puppet assembly. The puppet assembly is positioned into a center aperture in a book assembly and bonded therein.

  • Patent number: 8223626
    Abstract: A joint set of linear precoder designs is provided for single cell uplink multiuser space-time block coded multiple-input multiple-output (MIMO) systems with multi-packet reception by exploiting outdated channel state information. By deriving the pairwise error probability with respect to both minimum and average codeword distance design metrics, the technique solves an optimization problem subject to transmit power constraint for each user and dependent on the outdated channel state information. Due to the non-convex nature of the optimization problem, an iterative technique based on alternating minimization and projected gradient can be used to solve for a joint linear preceding structure for general space-time block coding. The linear precoding structure is then sent from the base station to various consumer premise equipment for use in later transmissions. For orthogonal space-time block code, a simplified distributed technique is provided to solve for a closed-form solution of the optimization problem.

  • Patent number: 7958712
    Abstract: A compact lawn mower that includes at least a shroud positioned a fixed distance from a lawn, by a common rear axle extended between and supported by a pair of rear wheels, is provided. The exemplary embodiment further includes a motor adjustment member confined within and supported by the shroud. The motor adjustment member interacts with a motor, which includes a cutting member attached to a motor shaft of the motor. By manipulating the motor adjustment member, the height of the cutting member relative to the ground surface is set. That is, the motor adjustment member is rotated in a first direction to move the motor closer to the lawn, and in the opposite direction to move the motor further from the lawn, allowing the grass to be cut to a desired length, while the shroud remains a fixed distance from the lawn.

  • Publication number: 20090183482
    Abstract: A compact lawn mower is disclosed. Preferably, the lawn mower includes at least a shroud positioned a fixed distance from a surface, such as a lawn, by a common rear axle extended between and supported by a pair of rear wheels. The preferred embodiment further includes a motor adjustment member confined within and supported by the shroud. The motor adjustment member interacts with a motor, which includes a cutting member attached to a motor shaft of the motor. Preferably, by manipulating the motor adjustment member, the height of the cutting member relative to the surface is set.
