     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The inventor commonly refers to the device of the present invention as the “Rock-a-Bye Hammock”. present invention is an automatic hammock for babies that can be activated and controlled electronically. When in use the child is placed securely in the hammock and softly rocked to sleep, without manual application. The hammock provides a soothing motion that is helpful in lulling a baby to sleep. 
     As it can bee seen from the figures essential elements of the motorized hammock object of the present invention include: a base stand generally describing the shape of an inverted U ( 1 ), mounted on a plurality of feet ( 2 ); a rigid sling supporting an hammock seat ( 3 ), said sling having two ends a first end and a second end, said first end connected to a first vertical arm of the base stand via a free swinging bearing mechanism ( 4 ), said second end connected to a motor ( 5 ) installed on the opposite side of said base stand; and a main power source electrically connected with said motor. The motor is controlled by an ON/OFF switch connected via an electrical circuitry. In a separate embodiment of the present invention it is possible to remotely control the motor via a remote control ( 7 ), or a voice or light activated mechanism. 
     For example in the voice activated control, a microphone ( 8 ) capture the pulse generated in the air by the pronunciation of a plurality of pre set words. That pulse is processed via a CPU programmed with a voice recognition software that translates the pulse into an electric signal that ultimately activates the motion of the motor. Various commands can be programmed other than ON and OFF, such as Slow or Fast, with reference to the pace of the swinging, or slower and faster, respectively to increase or decrease the rate of the swinging action without fully stopping the swinging motion. 
     In one of the preferred embodiments of the present invention said motorized hammock further comprises a roof cover ( 9 ), that in a separate embodiment of the invention it is adjustable. Various materials can be used to built the rigid structures of the device object of the present invention such as: Aluminum, plastic polymers, metal alloys, and others. 
     Generally speaking the rigid components of the device including said base describing an inverted U, said plurality of feet, and said slings are attached to each other via adjustable joints that can either be made or plastic, metal, or metal alloys, or other suitable material. 
     The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. Because the percentage of each constituent can be varied, with any mixture the entire range of possible variations is called a system. In this respect, all of the various forms of an alloy containing only two constituents, like iron and carbon, is called a binary system, while all of the alloy combinations possible with a ternary alloy, such as alloys of iron, carbon and chromium, is called a ternary system. Examples of alloys include pewter, bronze, stainless steel, 14 carats gold, and brass. 
     Aluminum alloys are alloys in which the metal Aluminum (Al) is the predominant metal. The typical alloying elements are copper, magnesium, silicon and zinc. About 85% of Aluminum is used for wrought products, for example rolled plate, foils and extrusions. The most important cast Aluminum alloy system is Al—Si, where the high levels of silicon (4.0% to 13%) contribute to give good casting characteristics. Aluminum alloys are widely used in engineering structures and components where light weight or corrosion resistance is required and therefore are suitable for the structural material of the device of the present invention. 
     One notable Aluminum alloy is the Scandium-Aluminum alloy. The addition of scandium to Aluminum creates nanoscale Al 3 Sc precipitates which limit the excessive grain growth that occurs in the heat-affected zone of welded aluminium components. This has two beneficial effects: the precipitated Al 3 Sc forms smaller crystals than are formed in other Aluminum alloys and the width of precipitate-free zones that normally exist at the grain boundaries of age-hardenenable Aluminum alloys is reduced. Scandium is also a potent grain refiner in cast Aluminum alloys, and atom for atom, the most potent strengthener in Aluminum, both as a result of grain refinement and precipitation strengthening. Titanium based Aluminum alloys, which are stronger but heavier, are cheaper and much more widely used in commercial applications. The most efficient of metallic Aluminum-Scandium by weight is alloys contain between 0.1% and 0.5% (by weight) of scandium. 
     In a separate embodiment of the device of the present application the motorized hammock of claim one whereas said baby hammock is made of a fire retardant or fire resistant fabric that can also be safely washed in a commercial laundry machine (i.e. the fabric material is washable). Examples of fire retardant material that could be used for the fabric of the hammock, include but are not limited to: Twaron, TARAMID (a TARASafe trademark), NEMEX (a DuPont trademark), ARSELON-(Khimvolokno trademark), coated nylon, Carbon Foam, M5 fiber, Kevlar, TARACOMFORT (a TARASafe trademark), Proban fr cotton, PYROMEX (a trademark of Toho Tenax), Pyrovatex fr cotton, Dale Antiflame, Indura fr cotton, Technora, Teijinconex, Lenzing FR (fire retardant Rayon), Carbon X, Kanox, Mazic, Modacrylic, Kermel, PBI, and Benchmark FR. NEMEX, ARSELON, TARACOMFORT, and PYROMEX are trade marks registered with the USPTO and will not be used in a negative or disparaging way in the course of the present application. 
     Various straps and belts ( 10 ) placed in the body of the hammock are designed to keep the body of the child in place. The hammock itself is made by a flame retardant, washable material and hold onto the rigid structures either via sturdy clips ( 11 ), zippers, or a plurality of VELCRO® straps. 
     VELCRO is a Registered Trademark (RT) with the USPTO directed to “All-purpose straps also including hook and loop fasteners, all sold as a unit” belonging to: Velcro Industries, a Limited Liability Company with its main office in Curacao in the Netherlands Antilles and will not be used in a negative or disparaging way in the course of the present application. 
     Power to the swinging motor is supplied by an electrical power supply such as a power cord ( 15 ) attached to an electrical outlet. Alternatively the motorized hammock of can draw electrical power from a solar panel ( 13 ) that convert via a photovoltaic process light (radiative) energy into electrical energy, or from both. A battery bank ( 14 ) can also be used as a secondary power source. Glass math batteries have historically shown good results when coupled with solar panels. 
     the Rock-a-Bye Hammock is mounted on an aluminum base with rods on opposite ends to support the hammock. For convenience, the hammock is attached with sturdy clips to allow for removal and washing purposes. An electrical motor will swing the hammock at variable speeds in back-and-forth motion. An awning is also attached overhead to keep the child in his or her own restful world with fewer distractions. The awning is also helpful as protection from the sun if this product is utilized outdoors. The awning is provided by an electrical motor powered by electricity from a power outlet. The motor is fastened to the body of the hammock. 
     Some of the materials considered for the manufacturing could be, but are not limited to, aluminum or light weight steel for the base. Materials for constructions include but are not limited to wood, wool, lead, aluminum, plastic, glass, ropes, cotton, fleece, micro fiber, or any other similar materials. Basic components are roof cover, motor, feet, hammock, and a power cord. 
     In a further embodiment of the device disclosed in the present application distance holder (spacers) ( 6 ) may be inserted to help maintaining the distance between the “legs” described by the downcoming sides of the inverted U base member. As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
