Abstract

A hand held device includes an oscillator driving a microcontroller having as a part of its program a counter actuable by a user to initiate a program count function, counting through a predetermined range of numbers until the program count function is terminated manually at any moment of the user'"'"'s choosing. A further feature permits the base frequency of the oscillator, and thus the counting rate of the counter, to be varied as a function of some external parameter such as a biometric parameter of the user, for example, by detuning the oscillator through a touch pad on the device housing. Visual and/or audible indicia provide a perceptible indication of the relative counting rate. A further, optional feature permits replacement game parameter data to be downloaded from an external source, and stored in nonvolatile memory for use by the microcontroller.

Claims

1. A handheld device for randomly selecting at least one number, comprising:

a sensor for detecting a biometric parameter of a user in proximity to said sensor and outputting an electrical signal that varies based on said biometric parameter;

a square wave oscillator for providing an output signal having a base frequency, wherein said oscillator is connected to said sensor so that said base frequency is at least partially dependent on said variable electrical signal;

a microcontroller connected to said oscillator to receive said output signal, wherein said microcontroller is programmed to increment through a sequence of numbers at a rate determined by said base frequency of said output signal.

2. The device of claim 1, further comprising a user interface connected to said microcontroller, wherein said user interface includes an input for interrupting said microcontroller when incrementing through said sequence of numbers to select a particular number.

3. The device of claim 2, wherein said user interface includes a second input for allowing a user to input a range of numbers to comprise said sequence of numbers that are incremented by said microcontroller.

4. The device of claim 3, wherein said user interface includes a third input for allowing a user to select one of a plurality of inputted ranges of numbers to comprise said sequence of numbers that are incremented by said microcontroller.

5. The device of claim 4, further comprising a display connected to said microcontroller.

6. The device of claim 5, wherein said microcontroller is programmed to display said particular number selected by said user on said display after said user interrupts the incrementing through said sequence of numbers.

7. The device of claim 6, wherein said microcontroller is programmed to display a user perceptible indicia corresponding to the base frequency of said oscillator.

8. The device of claim 7, further comprising a fourth user input for reinitiating incrementing through said sequence of numbers.

9. The device of claim 8, wherein said microcontroller is programmed to reinitiate incrementing through said sequence of numbers in response to activation of said fourth user input.

10. The device of claim 9, wherein said microcontroller is programmed to reinitiate incrementing through said sequence of numbers a predetermined number of times.

11. The device of claim 10, further comprising an interface connected to said microcontroller, wherein said microcontroller is programmed to receive instructions through said interface that define the predetermined number of times that said microcontroller can reinitiate incrementing through said sequence of numbers.
