Abstract: Some embodiments include a game of poker in which player actions are fixed by game rules.

Abstract: A simulated eye is capable of being changed between a normal state and a dilated state. The simulated eye includes a circuit board, a controller electrically connected to the circuit board, a simulated iris electrically connected to the circuit board, and a simulated pupil. When the simulated iris is irradiated with light, the size of the colored area of the simulated iris is changeable by operationally powering on and powered off the simulated iris via the controller, whereby the simulated eye is changed between the normal state and the dilated state.

Abstract: A transmitter together with appropriate software are configured in the shape and form of a remote control unit for use with a handheld game player device. The transmitter may use a conventional radio frequency link to transmit commands to a radio controlled device such as a toy car. The remote control unit, consisting of the transmitter and a game cartridge, is inserted into the game device so that the game player device provides control input and display functionalities to and for the remote control unit. The game player may support synthesis, simulation and testing of a route to be traversed by the radio controlled device.

Abstract: A main rotor is provided for use in a rotary winged model aircraft. The main rotor includes a rotor hub assembly rotatable about a vertical axis and at least two main rotor blades. Each of the main rotor blades extends in a radial direction from the rotor hub assembly. The main rotor blades each include a tip end positioned to lie in spaced-apart relation to the rotor hub assembly and a root end coupled to the rotor hub assembly for pivotable folding movement from an initial horizontal position perpendicular to the vertical axis about a horizontal axis through a desired folding angle of about 90.degree.. Forces transmitted to the rotor hub by the rotor blade during a crash-landing of a rotary winged model aircraft including the main rotor are minimized due to movement of the rotor blades through the desired folding angle.
