20090075786 | SEATED EXERCISE APPARATUS - A seated exercise apparatus comprises a frame having a seat attached to the frame. A pair of opposed cranks are rotatably coupled to the frame such that they rotate about a first axis. A medial portion of each of a pair of elongated members are rotatably connected to the frame at a second axis. A first end of each elongated member has a handle and a second end of each elongated member is rotatably connected to a one end of a respective pedal arm. The other end of each pedal arm is in turn rotatably connected to a respective crank. Each pedal arm also has a pedal adapted to receive a user's foot. In operation, the apparatus provides the user with coordinated seated exercise of both the arms/hands and legs/feet. The feet move in a generally reciprocating up and down motion and the arms move in a coordinated generally arcuate motion. | 03-19-2009 |
20140038789 | SEATED EXERCISE APPARATUS - A seated exercise apparatus comprises a frame having a seat attached to the frame. A pair of opposed cranks are rotatably coupled to the frame such that they rotate about a first axis. A medial portion of each of a pair of elongated members is rotatably connected to the frame at a respective pivot joint. A first end of each elongated member has a handle and a second end of each elongated member is rotatably connected to a one end of a respective pedal arm. The pivot joints are located outside of a plane of motion of their respective right and left pedals, such that the apparatus can fit within a more compact form factor, especially in a longitudinal dimension. The pedals move in a reciprocating path having an elliptical shape, in which the major axis is more vertical than horizontal, giving a more up and down, natural, pedal motion. | 02-06-2014 |
20140051552 | ELLIPTICAL MOTION EXERCISER - An exercise apparatus includes a frame, a crank with left and right crank arms rotatably coupled to the frame and left and right exercise assemblies. Each of the exercise assemblies includes a pedal link, a foot pedal coupled to a rearward portion of the pedal link, a rocker link having a lower portion pivotally coupled to the forward end of the pedal link and an upper portion pivotally coupled to the frame, and a driver link having a forward portion pivotally coupled to a respective crank arm and a rearward portion pivotally coupled to the pedal link. A flexible connecting member is coupled to the pedal links or the driver links and to a pivoting assembly mounted on the frame. The left and right foot pedals reciprocate forwardly and rearwardly in coordination with rotation of the crank and reciprocate upwardly and downwardly in coordination with rotation of the pivoting assembly. | 02-20-2014 |

20150163002 | Wireless Fire System with Idle Mode and Gateway Redundancy - A method and apparatus that includes the steps of providing a plurality of wireless nodes including at least one parent node and at least one child node, a control panel sending instructions to and receiving data from the plurality of nodes through a primary gateway and a wireless subsystem of the gateway, the primary gateway synchronizing the plurality of nodes by periodically transmitting a synchronization signal and one of the plurality of nodes detecting failure of the gateway and transmitting an idle synchronization signal for so long as the one of the plurality of nodes detects failure of the gateway. | 06-11-2015 |
20150163758 | Synchronization of Outputs in a Wireless Fire System - A method and apparatus that including a control panel sending an activate output command, a gateway of the control panel receiving the activate output command and determining a time period until a wireless communication subsystem becomes available, the wireless subsystem adjusting the determined time period by determining a time until a node is available to receive the output command through the gateway and wireless subsystem, the wireless subsystem sending the output command and a value of the adjusted determined time period to the node and the node activating an output device based upon the output command and adjusted determined time period. | 06-11-2015 |
20150294509 | System and Method to Select and Characterize Building Floors Using 2D Representations - A system includes a two dimensional display device coupled to control circuitry. The control circuitry establishes a two dimensional representation of at least first and second floors of a building. Responsive to a selected input closed boundaries are established which surround the two dimensional representations of each floor. Responsive to at least one other input, first and second coordinate systems are established with one coordinate system associated with each boundary. Three dimensional information can be established relative to the various devices installed on each floor, and, simulations of operation can be carried out. An installer can move various of the devices and re-run the simulation to evaluate which configuration provides a better communication result. | 10-15-2015 |
