  • Patent number: 9550128
    Abstract: In an aspect, a toy character assembly is provided, and includes a housing, a toy character, at least one sensor and a controller. The toy character is positioned inside the housing and includes a breakout mechanism that is operable to break the housing to expose the toy character. The at least one sensor detects interaction with a user. The controller is configured to determine whether a selected condition has been met based on at least one interaction with the user, and to operate the breakout mechanism to break the housing to expose the toy character if the condition is met. Optionally, the condition is met based upon having a selected number of interactions with the user.

  • Patent number: 9095781
    Abstract: A pop action toy assembly having a disc with a top surface, a bottom surface, a peripheral edge. The disc is formed to have a first stable configuration and a second stable configuration, wherein the disc can be inverted between the two stable configurations. The disc assumes the first stable configuration when symmetrically bent around a first axis so that its top surface is concave. The disc assumes its second stable configuration when symmetrically bent around a second axis so that the top surface is convex. The first axis and second axis are in the same plane and are generally perpendicular to each other. The invertible pop action toy is manually set into its second stable configuration. The invertible pop action toy is then dropped against a hard surface. Upon impact with the surface, the invertible pop action toy snaps back into its first stable configuration.

  • Patent number: 8628372
    Abstract: An actuator assembly including a resilient substrate having one or more shape memory alloys secured to the substrate. The shape memory alloys are configured to move a portion or all of the actuator assembly between an at-rest configuration and an actuated configuration. The shape memory alloys are elastically bendable and can be contracted from an elongated length to a contracted length in response to transmission of an electrical current therethrough. The electrical current is of a magnitude sufficient to heat the shape memory alloys from a first temperature to a second temperature so that a portion of or the entire actuator assembly can move from the at-rest configuration to the actuated configuration. Termination or reduction of the electrical current allows the shape memory alloy to cool and thereby elongate from the contracted length to the elongated length.

    Abstract: A color-changeable toy having a toy body to which a quasi-reversible thermochromic material is applied in a pattern. This material stably holds either of two colored states in a range of ordinary room temperatures. However, the material reversibly changes to one of the states above this range and to the other below this range. Thereby, by using commonly available heat and chilling sources such as ice, hot water or breath, one of the colors can be selected. A breath blow pipe can be used in conjunction with the toy and have an external appearance associated with that of the toy, e.g., gun and soldier.

    Abstract: This invention provides a toy vehicle incorporating actuators made from a shape memory alloy material. These actuators may be in the form of a spring, wire or similar form that has a mechanical response upon the application or removal of heat. In particular, wires may be connected about hinges for doors, hoods, convertible roofs and other such items which, upon the application of heat to the wire of shape memory ally, causes contraction of the wire and rotation about the hinged joint of the body part. As such shape memory ally actuators are generally only operable in a single direction, they may be provided in pairs or in opposition to another biasing means to cause the opposed rotation about the joint when desired. The preferred source of heat to the shape memory alloy actuators is through the provision of electrical energy to the wire to create heat through the resistance of the shape memory alloy actuator itself.

The diver is weighted for near-neutral buoyancy. The upper portion of the column is shaded, and the lower portion is subjected to thermal radiation such as sunlight. When radiation strikes the diver, it heats the gas, thereby increasing the gas volume, displacing liquid and increasing the buoyancy of the diver. The diver therefore rises to the shaded region where the gas cools, causing the diver to sink. The cycle repeats.

In one embodiment, the ornament is configured as a pendent and resembles an Aladdin's lamp having a jewel at its center and a generally hemispherical hollow jewel cover coupled to the pendent body by an integrally molded hinge. In an alternate embodiment, the ornament is formed in a flower-like shape having a plurality of radially extending petals and is securable to the wrist of a toy figure. The petals are movable between an open bloomed position exposing the jewel and a closed bud-like position fully enclosing the jewel. The ornaments are thermally set in the closed position by manually forcing the ornament to the closed position after warming and temporarily immersing the ornament in a cold water bath.

  • Patent number: 5376772
    Abstract: An electrothermal color-varying instrument for inducing color change in a color-varying layer includes a heat generating element composed of a sintered barium titanate thermistor in face-to face contact with a heat transmitting member having a heating end portion for transmitting heat to the thermal color-varying layer. The thermistor has:(i) a positive temperature coefficient on the electrical resistance within a temperature range from 25.degree. C. to 70.degree. C.;(ii) a volume resistivity at 25.degree. C. (.rho..sub.25) within a range of 9.8.times.10.sup.-3 to 2.97.times.10.sup.5 .OMEGA..multidot.cm; and(iii) a ratio (.rho..sub.70 /.rho..sub.25) of the volume resistivity at 70.degree. C. to that at 25.degree. C. within a range of 5.ltoreq.(.rho..sub.70 /.rho..sub.25).ltoreq.400.The electrothermal heat generating element generates heat under the application of a voltage in the range of 0.8 to 40 volts and maintains a saturated heating temperature within a range of 30 to 100 degrees C.

  • Patent number: 5348300
    Abstract: A set of dice, each die being a transparent, six-sided cube. A number of extrusions or marking indicia are located on each of the outer surfaces of the dice and are numbered, lettered or otherwise designated. The interior of each die is hollow, with small impressions on the inner surfaces located directly opposite the extrusions. A ball is disposed inside each die and is free to move around the hollow interior. The interior impressions are sized so that the ball will settle in one of the impressions when the die comes to rest after being thrown. Each of the impressions lies directly beneath a an extrusion or marking indicia on the upwardly facing outer surface of the die, which is read to determine the outcome of the toss. Thus, each toss of the dice will generate different numbers for use in games of chance such as lotteries and the like.

  • Patent number: 5316513
    Abstract: There is disclosed an electrothermal color-varying device inducing color change in a thermally color-varying layer by heat generation in an electrothermal heat-generating member, in which the heat-generating member is composed of a non-metallic member having a positive temperature coefficient on the electric resistance at least in a temperature range 25.degree. C. to 65.degree. C. and a particular volume resistivity, is adapted to generate heat by the application of a low voltage and is capable of self-control of the saturated heating temperature at an arbitrary temperature within a range of 25.degree. C. to 65.degree. C., whereby improved safety is achieved without the danger of overheating or current leakage. Also there are disclosed toys utilizing such color-varying device.

  • Patent number: 5299971
    Abstract: An automatic passive interactive tracking device is disclosed which provides for the detection of intruders with a single quadruplex stationary passive infrared sensor covering a relatively wide field of view. Alternatively, two dual sensors may be incorporated. The stationary sensor or sensors provides a signal to a microcontroller, which drives a stepper motor to rotate additional sensors with narrower fields of view to more precisely determine the exact bearing of the intruder. By incorporating appropriate analog to digital conversion and algorithms in the microcontroller, approximate range may also be determined. When the intruder has been verified by all of the sensors, a camera and/or light is activated to record the intruder. A number of the tracking devices may be linked together to cover a larger area, and may provide signals to a remotely located monitor and/or security post.
