  • Patent number: 10487525
    Abstract: An electrically powered pool cleaner may include a housing defining an axial passageway. A rotatable sleeve impeller may be supported by the housing within the axial passageway. The axial passageway may include an unobstructed central portion for passage of fluid and pool debris therethrough into a filter bag removably connected to the housing. A motor may be operatively connected to the sleeve impeller and a power supply operatively connected to the motor. Rotation of the sleeve impeller may accelerate fluid flow through the axial passageway for drawing debris in the pool into the filter bag.

  • Patent number: 10328305
    Abstract: In an exercise machine, foot platforms may travel in inclined circular paths to establish three dimensional operational characteristics. Platform support members may be rotationally synchronized by connected mechanical components such that they are maintained out of phase with each other by one half of a cycle or 180 degrees in counter rotational directions. Crank synchronization in an inclined plane during operation of the exercise machine may provide three-dimensional foot travel in vertical, lateral and longitudinal directions.

  • Patent number: 8574130
    Abstract: An exercise apparatus includes a frame, a footpad for supporting a user's foot, and a sensor that generates a force indicating signal indicative of a force applied to the footpad in a horizontal direction by the user's foot. A mechanism couples the footpad to the frame and guides the footpad in a closed path having at least first and second mutually perpendicular dimensions in response to forces applied to the footpad by the user's foot, the first dimension being parallel to said horizontal direction. The mechanism resists movement of the footpad in the horizontal direction in response to an electrical control signal supplied as input to the mechanism. A control system receives the force indicating signal and generates the control signal such that the mechanism resists movement depending on the force indicated by the force indicating signal.

  • Publication number: 20130288858
    Abstract: An exercise apparatus includes a frame for residing on a horizontal surface, a pair of arm-supporting members for supporting the user's arms and a pair of leg-supporting members for supporting the user's legs. A linkage assembly couples the arm-supporting members and leg-supporting members to the frame and moves the arm-supporting members and leg-supporting members in closed paths relative to the frame in response to user forces applied to the arm-supporting members and leg-supporting members. The linkage assembly includes actuators for adjusting dimensions of the closed paths in response to control signal inputs. Sensors mounted on the linkage assembly generate force-indicating signals representing user force. A user interface receives and processes the force-indicating signals and supplies the control signal inputs to the actuators. A dimension of at least one of the closed paths is a function of at least one of the forces applied to the leg and arm-supporting members.

  • Patent number: 8292787
    Abstract: An exercise apparatus includes a frame, an arm supporting member, and a leg supporting member. A sensor is connected to at least one of the arm supporting member and the leg supporting member, and/or a resilient member is interconnected between the arm supporting member and either the leg supporting member or the frame. The sensor communicates with a user display and/or a resistance device to indicate the amounts of work performed by the arm supporting member and the leg supporting member, and/or to adjust resistance to movement of the leg supporting member as a function of user force applied against the arm supporting member. The resilient member encourages synchronization of the arm supporting member and the leg supporting member, while allowing some relative movement therebetween.
