(1) Gravity assisted mechanical machine that uses a combination of stored mechanical energy plus the downward force of gravity, regulated by a motor and a sophisticated switch powered by a rechargeable battery. The mechanical switch is also assisted by a lever so the motor is more efficient in the use of the battery power. (2) Older types of fuel powered mechanical machines cause greater pollution and need an enormous amount of support to continue operating daily. (3) The gravity assisted mechanical machine can be used without air and operates longer and more efficiently and is less noisy and has no emissions to cause pollution. It will not heat up like a conventional mechanical machine only when attached to a generator for electrical energy. It will work without the need for the enormous weight of fuel to produce electrical energy. It can be used to power some electrical generators, example wind mill generators, for all uses of electrical energy.

An energy-saving power generator for generating a power by rotating a rotary member is described. A power generator 100 for generating a power by rotating a rotary member 10, comprising: opposing columns 20 (21, 22) for supporting the power generator 100; one or more movable inclined members 40 inclined from one column 21 to other column 22 for rotating the rotary member 10 and capable of ascending and descending along the columns by one or more roller members 30 arranged at opposite ends of the movable inclined members 40 and by roller receiving members 35 provided at the columns 20 (21, 22); and one or more fixed inclined members 60 inclined from the other column 22 to the one column 21 for rotating the rotary member 10 and provided at the columns 20 (21, 22) or at supporting members 50 for supporting the columns.

A patient interface comprises one or more electronic components for monitoring, diagnosing and/or treating a patient, the one or more electronic components being provided in, or on, one or more of a plenum chamber, a seal-forming structure and a positioning and stabilising structure of the patient interface; wherein the patient interface comprises and/or is communicable with a power system for powering the one or more electronic components.

The present invention provides systems and methods for production using manual labor. The present invention involves the transition of energies to perform labor. The transition involves manual labor energy turning into kinetic energy and further transition of the kinetic energy into mechanical or electrical energy used for performing designated labor.

The invention discloses a tension force stepless adjustment counterweight power generating mechanism and a fitness equipment with the same, comprising a pulling rope, a winding drum, a mounting seat, a central shaft, a spring, a generator, and a regulator; one end of the pulling rope is connected to the winding drum; a part of the pulling rope is wound on the outer peripheral wall of the winding drum; the winding drum is rotatably connected to the mounting seat; the outer end of the spring is connected to the winding drum, and the inner end thereof is connected to the mounting seat; the central shaft is rotatably arranged on the mounting seat. The mechanism organically combines the pulling force process with the power generation process, and uses a regulator to adjust the rotation damping of the generator motor shaft to adjust the pulling force in a disguised manner.

An implantable respiratory apparatus including an expandable/contractible element; wherein at least part of the element is configured to be anchored to the subject's chest bones.

Computer-processor controlled energy harvester system optimized for use on mobile platforms. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient acceleration as stored mechanical energy. The energy collectors are configured to move between a first position where the energy collector stores energy, to a second position where the energy collectors release stored energy to a geared electrical generator shaft, thus producing electrical energy, often stored in a battery. A plurality of processor controlled electronic actuators control when each energy collector stores and releases energy. The processor can use battery charge sensors, and suitable software and firmware to optimize system function. To facilitate use on mobile platforms, the processor also uses input from a 3-axis accelerometer to dynamically reconfigure the energy collectors according to the present major directions of ambient acceleration.
