Abstract: A mechanical eyeball includes an outer housing shaped as an ocular surface configured to rotate about a first rotational axis and a second rotational axis that intersect at a fixed center point. The outer is housing is coupled to a mechanical assembly, and the mechanical assembly is contained within a volume associated with the mechanical eyeball. The mechanical assembly can include a stationary gear train and rotatable components that rotate relative to the gear train. The rotatable components are configured to cause rotation of the outer housing about one or more rotational axes. The volume may be substantially the same volume of a human eye. The mechanical assembly is coupled to one or more drivers configured to actuate rotation of the outer housing.

Abstract: A squeezable tongue-wagging toy figure with a squeeze mechanism which includes a squeaker provided within a space defined by four hinged panels in elliptical cylinder shape, and a toothed rack meshed with a gear chain that is coupled with a bar with a toy tongue. When the panels are squeezed, the rack drives the gear chain in one direction and in turn pivot the bar towards one side and the squeaker produces a sound, and when the panels are released, the rack drives the gear chain in an opposite direction and in turn pivot the bar towards an opposite side and the squeaker produces another sound.

Abstract: An artificial eye structure rotates an artificial upper eyelid via the attraction between a number of electromagnetic elements disposed in a line and a magnet. The rotation angle of the artificial upper eyelid can be controlled by selectively magnetizing the electromagnetic elements.

Abstract: Toy dolls include a head having a face having an alterable appearance and a mechanism for altering the appearance of the face. The mechanism may include a first element configured to pivot about a first axis between a first position and a second position, a second element operatively coupled to the first element and configured to pivot about a second axis between a third position and a fourth position in response to the first element pivoting from the first position to the second position, and a third element operatively coupled to the first element and configured to pivot about a third axis between a fifth position and a sixth position in response to the first element pivoting from the first position to the second position. Pivoting the second element may alter a first aspect of the appearance of the face, and pivoting the third element may alter a second aspect of the appearance of the face.

Abstract: An artificial skin system for use with a robotic assembly such as to provide an animated robot head with realistic skin movement. The skin system includes a receiving component for contacting the manipulator mechanism of the robotic assembly and also includes an exterior skin component that extends over the receiving component. An inner surface of the exterior skin component is integrally bonded to the receiving component such that the exterior skin component moves with the receiving component when a manipulator mechanism or robotics anchored to the receiving component moves or applies a force. The exterior skin component is formed of an elastic material with a second hardness that differs from a first hardness of elastic material of the receiving component, e.g., is less than the first hardness. The skin system includes a backing component bonded to the other components with a third hardness less than the first and second hardnesses.

Abstract: An artificial eye suitable for realistic use in dolls that replicate human beings, animals, and other creatures such as dinosaurs, aliens, monsters, and the like. The artificial eyes, according to some embodiments of the present invention, have a one-piece eyeball and lid that are integrally molded. The integrally molded eye and lid of the present invention reduces the part count of the eye when compared to conventional two-piece eye/lid combinations, which lowers the cost of production by eliminating high cost, labor intensive secondary operations. Furthermore, the process used to create these high-quality artificial eyeballs is a high volume, low cost operation. Each embodiment of the present invention has one or more of the following elements: a bowl-shaped member, an eyelid integrally molded with the bowl-shaped member, a pupil visible through the bowl-shaped member, an iris-like member visible through the bowl-shaped member, and an attachment member to attach the artificial eye.

Abstract: A puppet (10) or other character representation includes an inner tube (11), an outer tube (12) and an extra tube (13) located within the inner tube (11). The upper ends of the inner and outer tubes (11 and 12) are connected by a sleeve (23) of simulation hair. A moulding (16) is secured to the outer tube (12) and has the appropriate facial characteristics including an opening (19) corresponding to the mouth of the character. The extra tube (13) has an upper edge which is connected to the part of the moulding (16) which provides the lower jaw of the character.

Abstract: A medical teaching doll is provided with devices for simulating the differences between normal organs, and organs which are physically altered by sickle cell or other disease. The devices simulate the normal and diseased conditions so that the differences can be clearly seen and/or felt. The doll is used to train parents to recognize the signs or symptoms of sickle cell disease so that they may seek medical care for their children before they become more acutely ill. The signs or symptoms which are simulated by the doll include change of color of eye sclera, enlargement of spleen, elevated temperature, labored breathing and/-or coughing, and change of color of skin.

Abstract: A doll with simulated physiological functions, in particular a toy doll in the form of a teddy bear, is described. The teddy bear has a head with eyes that can move and a mouth that opens and closes. A lower jaw pivots about a first axis to provide the opening and closing action of the mouth. A mechanical linkage means is provided to transmit a movement of the lower jaw to another part of the doll, for example to the eyes, whereby opening and/or closing of the mouth, for example when feeding the teddy bear, can produce a simulated physiological response from the doll, for example a responsive eye movement. The mechanical linkage means also actuates a sound generating means. The arrangement of the mechanical linkage means is such that there is a degree of unpredictability in the simulated physiological functions which enhances the long term play value of the doll and increases the enjoyment of a child. Incorporating other simulated physiological functions further enhances the play value of the teddy bear.

Abstract: An artificial eye that appears to look back at a plurality of observers simultaneously even while either change position.

Abstract: A child's toy is disclosed that provides for a character that is capable of both visually and audibly displaying a variety of emotional expressions and which is capable of providing these displays in combination with playing a "peek-a-boo" game with the toy character. The toy has a housing that is shaped like a teddy bear, with openings for the bear's eyes and mouth and a pair of paws that rotate to a position where both paws cover the eyes of the bear when mechanically activated by the child. The paws are mechanically interconnected to a disk mounted within the housing which contains different representations for the eyes and the mouth of the bear, each of which is configured to represent a different emotional expression, on its front surface. The representations for the eyes and the mouth of the bear appear through the eye and mouth openings in the bear's face.

Abstract: A device for bringing about the closure of one or both eyes of a doll composed of two rigid arms, one fixed and the other swinging. The arms pass through a mounting neck flange joining the head and body of the doll. The two arms are separated by a spring placed between them within the cavity of the body of the doll. A portion of the fixed arm within the head of the doll incorporates an axis for rotation of first ends of a pair of bent levers. The bent levers are equipped with slots through which a single pin is adapted to translate. The pins join to the end of an actuating lever affixed to the swinging arm. When manual pressure is applied to the body of the doll, the swinging arm is displaced toward the fixed arm causing the two bent levers to swing and their two free ends to move toward each other. The free ends are rotationally attached to portions above and below at least one eye, causing the eye to close.

Abstract: A toy figure having artificial eyes which when viewed by an observer, create, as a result of an optical illusion, apparent eyeball movement as the observer changes his orientation relative to the figure. Each artificial eye is constituted by a case formed of a transparent sphere or truncated sphere having a ball supported concentrically therein to simulate an eyeball. The artificial eye is mounted on the head of the figure to expose its convex frontal section, this being covered by a mask having a window therein which displays the eyeball and the regions above and below the eyeball and those on either side thereof. As a consequence, an observer looking at the artificial eye in a direction normal thereto in alignment with the eyeball center sees the eyeball in its centered position.

Abstract: A toy doll with arms and legs mounted for pivotal movement relative to the torso in response to rotational movement of a bottle nipple in the doll's mouth. One gear on a rotatable feed tube within the hollow head of the doll engages vertically oriented racks that then engage spur gears to rotate the arms. A bevel gear also carried by the tube engages a bevel gear on a depending drive shaft that has a crown gear driving a bevel gear for each of the legs. Both the arms and the legs are mounted on spools that freely rotate with respect to the torso. Frictional engagement of the limbs with respect to the spool permit the spool to pivotally drive the arms while also allowing selective, independent angular orientation of each of the limbs with respect to its respective spool.
