Abstract: A portable inflation device having a pump, a control device, a user interface, and an inflation indicator. The pump includes an elongated hose with an inflation nozzle. The control device controls operation of the pump and is configured to sense a current pressure of an object, calculate the estimated remaining time to inflate the object to a target pressure, and display the remaining time using the inflation indicator. The user interface is configured to allow a user to enter the target pressure into the control device.

Abstract: A voice discriminating system is disclosed which includes input circuitry for a pair of microphones, circuitry for detecting the presence of voiced sounds inputted to the microphones, selectively enabled circuitry for detecting the presence of unvoiced sounds inputted to the microphones, and a microcontroller which executes functions under the control of the presence or absence of voiced or non-voiced sounds inputted to the microphones. The disclosed system further includes a display circuit and a sound circuit that are controlled by the microcontroller for the purpose of playing games wherein the players provide spoken commands to the microphones.

Abstract: A toy car adapted to travel on a track assembly is disclosed. The toy car includes a motor coupled to a drive train which drives the car forwards regardless of a direction of rotation of an output shaft of the motor. The drive train includes a first set of gears coupled with a first one-way clutch to drive an axle of the car when the output shaft of the motor rotates in a first direction. The drive train also includes a second set of gears coupled with a second one-way clutch to drive the axle when the output shaft rotates in a second direction. The first set of gears represent a higher gear reduction ratio from the output shaft to the axle than the second set of gears whereby a speed of the forward motion of the car may be altered by reversing the direction of rotation of the motor. The motor of the car draws electric power from the track assembly.

Abstract: A toy oven assembly having a light bulb acting as a light and a heat source, is disclosed. The toy oven includes two identical component parts which are assembled to one another. In their assembled form they incorporate a substantially circular opening on a substantially horizontal top surface of the assembly. The circular opening is surrounded by a rim. A translucent or transparent dome shaped member is disposed above a heating chamber of the toy oven assembly and is held by the rim so that during operation of the toy oven assembly the dome shines with light giving the toy an interesting science fiction like appearance.
