Patent number: 7351187Abstract: An exercise device includes pedals, a belt and a hydro-kinetic brake. A user applies muscular force to the pedals and the pedal belt transfers the motion of the pedals to a flywheel shaft of the fluid brake. The pedals may be configured to accept force from a hand, foot, arm, leg and/or neck of the user. The amount of work performed by the user is derived by measuring the relative rotational speeds of two radial-blade impellers of the fluid brake. The wattage exhibited by the fluid brake during the exercise session may be recorded and associated with an identified user, whereby records of the exercise performance of an individual may be updated.Type: GrantFiled: October 20, 2006Date of Patent: April 1, 2008Inventor: Joseph Seliber

Patent number: 7341545Abstract: Steel cables on fitness equipment, through repeated use, will build up undesired torque, due to irregular and unpredictable turns and spins. Such accumulated and undesired torque has a tendency to cause the cable to derail from the grooves on the gears it is supposed to stay and slide. The grab bar or handle bar, where a user grabs to start workout routine, likewise, has a tendency to turn or spin in an uncontrollable way and could potentially injure a user. Present invention effectively releases the undesired torque and restores the cable to its neutral and relaxed state, so that the fitness equipment will experience less malfunctioning, and user safety is enhanced.Type: GrantFiled: May 28, 2004Date of Patent: March 11, 2008Inventor: Guofang Cao

Patent number: 7325541Abstract: An adjustable primary air supply for wood burning device comprises at least one but preferably two thermostatic bimetal elements which, by bending with temperature variations, directly actuate a flap that opens and closes the air entry opening. Primary Air is the air used to control the burn rate and it is adjusted in order to achieve the desired burn rates and Secondary Air is the air used to complete the combustion and is not adjustable. Using these two sources of air, the invention consists of a device, which allows the primary air supply to remain open until proper burning is established. Therefore, when the temperature of the appliance rises, the combustion air gradually decreases to its preset value by having the primary air supply automatically shut off as temperature increases. A higher temperature indicates that the wood is sufficiently hot to decompose into flammable gases, so only secondary air is required to continue the combustion process.Type: GrantFiled: June 28, 2005Date of Patent: February 5, 2008Inventor: Emmanuel Marcakis
