Publication number: 20080188159Abstract: There is illustrated and claimed the structure and method for performing a certain set of sequences of a toy character. Depending on the programming of a microprocessor and the functioning of various motor means the character can go from a standing position to a sitting position; a standing to a sitting position and a back position and back to a standing position, and a standing to a sitting position, a back position, a rollover position and, eventually, back to a standing position. The character is also capable of performing other functions.Type: ApplicationFiled: September 18, 2006Publication date: August 7, 2008Inventors: Bruce D. Lund, Michael D. Starrick, Paul N.

Patent number: 6736693Abstract: A doll that includes a pair legs pivotally attached to a torso. The torso having a front side and backside. A pair of motor mechanisms separately attached to each leg for pivoting the legs forwards and backwards in accordance to a set of pre-programmed positions that moves the doll from a first orientation to a second orientation. The movement may be defined as rolling the doll from its front side to its backside and vice versa, as well as moving the doll to a standing position and walking the doll while it is standing.Type: GrantFiled: December 28, 2001Date of Patent: May 18, 2004Assignee: Lund and CompanyInventors: Bruce D. Lund, Krishnan Srirangam, Michael Starrick, Sunil Moothedath

Patent number: 6672935Abstract: The present invention includes a toy figure that is hinged at the waist. The hinged waist permits the figure to pivot or move the top half of the body relative to the bottom half. A control mechanism controls the movement such that the figure will move from a standing position through a “somersault” ending back in a standing position again. In other embodiments the control mechanism can stop the movement or pose the figure in a position, such as a “headstand” or a position prior to a headstand. When the figure stops the movement prior to a headstand, the figure can prompt a user to assist the figure in completing the headstand. When the user helps the figure in completing the headstand, the figure could continue to perform a somersault or flip over.Type: GrantFiled: July 10, 2002Date of Patent: January 6, 2004Assignee: Lund & CompanyInventors: Bruce D. Lund, Krishnan Srirangam, Michael Starrick, Sunil Moothedath

Patent number: 6669484Abstract: An interactive microscope assembly wherein when a slide is placed on a holder a program will audibly identify the slide. A keypad is used to input the slide number and a built-in program provides relevant information. An indexing system is also provided which in conjunction with a series of buttons provides audio information relating the portion of the specimen to which the indexing system is directed.Type: GrantFiled: August 24, 2001Date of Patent: December 30, 2003Assignee: Lund & CompanyInventors: Bruce D. Lund, Krishnan Srirangam

Patent number: 6666745Abstract: The present invention includes a doll that has a torso hingedly attached to a pair of legs. Springs are attached to the torso and legs for exerting a spring force that keeps the torso and legs in a substantially planar position. A motor mechanism attached to the torso and legs for moving the torso and legs towards each other against the springs. A circuit board in communication with the motor mechanism controls the torso and legs such that the doll hops along a surface.Type: GrantFiled: August 27, 2002Date of Patent: December 23, 2003Assignee: Lund and CompanyInventors: Bruce D. Lund, Krishnan Srirangam

Patent number: 6645036Abstract: The present invention includes a toy figure having a torso connected to a first leg and a second leg. A first motor is secured in the torso and is in communication with a first gear train, which is meshed to a fastener in the first leg, such that when the figure is in a standing position, the first motor causes the torso to move in relation to the first leg. A second motor is secured in the second leg and is in communication with a second gear train, which is rotatably attached to the torso such that when the figure is in the standing position, the second motor causes the second leg to move in relation to the first leg along the axis. A circuit board has pre-programmed instructions that when the figure is in the standing position controls the motors such that the figure walks across the surface.Type: GrantFiled: January 22, 2003Date of Patent: November 11, 2003Assignee: Lund and Company Invention, L.L.C.Inventors: Bruce D. Lund, Michael Starrick, Krishnan Srirangam, Sunil William Moothedath

Patent number: 6537127Abstract: In one embodiment the kisses that the doll may perform are “raspberry kisses”, “eskimo kisses” and regular kisses. To simulate a raspberry kiss a motor mechanism in the mouth of the doll causes the lips to vibrate, which causes a child to feel a tingling sensation when the child presses against the vibrating lips. To simulate an eskimo kiss the motor mechanism alternatively causes the head of the doll to move side-to-side, which when a child places their nose up against the doll's nose causes a rubbing feeling. The doll also includes a speaker to emit various sounds that coincide with the kisses. The doll will also give regular kisses that do not use the motor mechanism and are simply a kissing sound that emanates from the speaker. Various sensors or mechanical switches are used to activate the various kisses and sounds.Type: GrantFiled: August 27, 2002Date of Patent: March 25, 2003Assignee: LUND and CompanyInventors: Bruce D. Lund, Krishnan Srirangam, Michael Starrick

Patent number: 6506095Abstract: The present invention includes a doll defined by an upper half hingedly attached to a lower half. A spring means attached to the upper and lower halves resiliently place the halves in a substantially planar position. A locking mechanism is included for retaining the halves in a substantially non-planar position, when the locking mechanism is engaged. A motor means is also attached to the upper and lower halves for moving the halves in a substantially non-planar position. When the motor means moves the upper and lower halves a predetermined distance, the locking mechanism engages and the upper and lower halves are maintained in the substantially non-planar position. The doll may be moved from a standing position into a sitting position; from a sitting position into a laying position; a laying position into a sitting position and a laying position into a laying position with the lower half angled upwardly.Type: GrantFiled: January 30, 2002Date of Patent: January 14, 2003Assignee: Lund & CompanyInventors: Bruce D. Lund, Krishnan Srirangam, Sunil Moothedath, Michael Starrick
