Abstract

An impulsive communication activated device for connection to a computer input port for controlling a computer, is disclosed. The disclosed device includes an output connector for communicating with the computer input port, and includes a sensor for detecting an impulsive communication such as a hand clap or other predetermined input, to generate an impulsive signal. The disclosed device includes a comparator for responding to both a reference signal and to the impulsive signal, and to determine if the impulsive signal differs substantially from the reference signal to generate a start signal. The disclosed device includes a logic circuit responsive to the start signal for generating a predetermined computer command signal to control the computer.

Claims

1. A method for controlling a computer having an operating system via a USB port engageable device in a self-contained compact package having a USB output connector for connecting to a computer USB input port, the device including a microprocessor and a memory and having a housing being substantially smooth on all sides, comprising:

storing enumeration data in the memory to describe the device as a human interface device to the computer;

storing report descriptor data in the memory to describe the device as a keyboard to the computer;

storing in the memory a single byte sequence corresponding to preselected keyboard emulating signals to instruct the operating system of the computer to switch from an active program currently running to another desired program, each program having a respective active computer display;

detecting an impulsive communication in the form of a sharp sound;

generating an impulsive signal in response to the detected impulsive communication;

responding to the impulsive signal to generate a start signal;

retrieving and sending in response to the start signal the enumeration data to the computer identifying the device as a human interface device to the computer;

retrieving and sending the report descriptor data to the computer in response to a request from the computer to describe the device as a keyboard to the computer;

responding to the start signal using the microprocessor for retrieving and sending the stored single byte sequence corresponding to the preselected keyboard emulating signals to the operating system of the computer via the USB output connector to switch from the currently running active program; and

commanding the operating system of the computer via the USB connector to switch between the initial active computer display and the desired active computer display in accordance with the single byte sequence,

wherein the operating system of the computer remains in an active state with the active program associated with the desired active computer display being available to the user for immediate use,

wherein the number of preselected keyboard emulating signals being stored is substantially fewer than the number of conventional keyboard signals in a conventional keyboard, and

wherein the desired active computer display and its active program are stored externally from the device.

2. A method as recited in claim 1, further including:

generating a second start signal; and

responding to the second start signal via the microprocessor for retrieving and sending preselected keyboard emulating signals to control the operating system of the computer via the USB output connector to switch from the currently active running program.

3. A method as recited in claim 2, wherein the first start signal clears an active window on the computer and the second start signal restores the active window on the computer.

4. A method as recited in claim 1, further including receiving power from the USB input port of the computer via the USB output connector.

5. A method as recited in claim 4, wherein generating the start signal is responsive to receiving power from the USB input port of the computer.

6. A method as recited in claim 1, wherein generating the start signal includes using a sensor.

7. A method as recited in claim 1, wherein the generating of the start signal also includes operating a manually operable switch.

8. A method as recited in claim 1, further including:

detecting a signal from the computer indicating its unique state;

subsequently generating a second set of preselected keyboard emulating signals via the USB output connector upon generation of another start signal, the second set of preselected keyboard emulating signals being related to the unique state.

9. A method for controlling a computer having an operating system via a USB port engageable device in a self-contained compact package having a USB output connector for connecting to a computer USB input port, the device including a microprocessor and a memory and having a housing being substantially smooth on all sides, comprising:

storing enumeration data in the memory to describe the device as a human interface device to the computer;

storing report descriptor data in the memory to describe the device as a keyboard to the computer;

storing in the memory a single byte sequence corresponding to preselected keyboard emulating signals to instruct the operating system of the computer to run a desired program with a desired active computer display over an initial active computer display;

wherein the operating system of the computer begins in an initial active state, with an initial program associated with the initial active computer display being available to the user for immediate use;

detecting an impulsive communication in the form of a sharp sound;

generating responsive to the detected impulsive communication an impulsive signal;

generating a start signal responsive to the impulsive signal;

retrieving and sending in response to the start signal the enumeration data to the computer identifying the device as a human interface device to the computer;

retrieving and sending the report descriptor data to the computer in response to a request from the computer to describe the device as a keyboard to the computer;

responding to the start signal using the microprocessor for retrieving and sending the stored single byte sequence corresponding to the preselected keyboard emulating signals in response to the start signal via the microprocessor to the operating system of the computer via the USB output connector to run the desired program; and

commanding the operating system of the computer via the USB connector to open the desired active computer display over the initial active computer display,

wherein the operating system of the computer remains in a desired active state with the desired program associated with the desired active computer display being available to the user for immediate use,

wherein the number of preselected keyboard emulating signals being stored is substantially fewer than the number of conventional keyboard signals in a conventional keyboard, and

wherein the desired active computer display and the desired program are stored externally from the device.
