Abstract

Abstract A system includes a power supply unit adapted to provide power from a separate backup source of power to a computer in the event of an interruption in a primary source of power, the unit having a size and shape adapted to be set on a support surface in a position above a keyboard utilized to provide input to the computer. An illumination panel, including at least one lamp on the power supply unit, illuminates the keyboard when activated, and a control circuit activates the illumination panel utilizing the backup source of power when there is an interruption in the primary source of power.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 157 words
A system, comprising: a power supply unit adapted to provide power to a computer from a separate backup source of power in the event of an interruption in a primary source of power that otherwise provides power to the computer, the unit having a size and shape adapted to be set on a support surface in a position above a keyboard utilized to provide input to the computer; illumination means, including at least one lamp mounted on the power supply unit, for illuminating the keyboard; control means for activating the illumination means with power from the backup source of power when there is an interruption in the primary source of power; a case housing the power supply unit; and a forward portion of the case adapted to overhang the keyboard when the case is set on the support surface in a position above the keyboard and support the illumination means in a position to illuminate the keyboard.
Claim 2
Independent Claim 157 words
A system, comprising: a power supply unit adapted to provide power to a computer from a separate backup source of power in the event of an interruption in a primary source of power that otherwise provides power to the computer, the unit having a size and shape adapted to be set on a support surface in a position above a keyboard utilized to provide input to the computer; illumination means, including at least one lamp mounted on the power supply unit, for illuminating the keyboard; control means for activating the illumination means with power from the backup source of power when there is an interruption in the primary source of power; a case housing the power supply unit; and a forward portion of the case adapted to overhang the keyboard when the case is set on the support surface in a position above the keyboard and support the illumination means in a position to illuminate the keyboard.
Claim 3
Dependent Claim 42 words
A system as recited in claim 1, wherein: the illumination means is mounted on a lower portion of the forward portion in a position such that a substantial portion of light emanating from the illumination means is directed downwardly toward the keyboard.
Claim 4
Dependent Claim 60 words
A system as recited in claim 2, wherein: the illumination panel is mounted on the lower portion in a position such that light emanating from the illumination means covers a keyboard-size area at a distance approximately equivalent to the distance from a conventional keyboard tray to the top of a conventional personal computer supported on a conventional keyboard tray support.
Claim 5
Dependent Claim 25 words
A system as recited in claim 1, wherein: the case has a size and shape adapted to be supported by a conventional keyboard tray support.
Claim 6
Dependent Claim 24 words
A system as recited in claim 1, wherein: the case has a size and shape adapted to be supported atop a conventional personal computer.
Claim 7
Dependent Claim 23 words
A system as recited in claim 1, wherein: the case has a size and shape adapted to support a conventional computer display monitor.
Claim 8
Dependent Claim 16 words
A system as recited in claim 1, wherein the illumination means includes: a plurality of lamps.
Claim 9
Dependent Claim 20 words
A system as recited in claim 7, wherein: the lamps are adapted to be powered by a twenty-four volts DC
Claim 10
Dependent Claim 43 words
A system as recited in claim 1, wherein: the control means is adapted to activate the illimination means when there is an interruption in the primary source of power and deactivate the illumination means when the primary source of power is again stabilized.
Claim 11
Independent Claim 148 words
A system, comprising: a case having a size and shape adapted to house a power supply unit and be supported atop a conventional personal computer that is supported above a keyboard; a forward portion of the case adapted to overhang the personal computer; at least one lamp mounted on a lower portion of the forward portion in a position such that a substantial portion of light emanating from the lamp is directed downwardly toward the keyboard when the lamp is turned on; a power supply unit substantially within the case that is adapted to provide power to the computer from a separate backup source of power in the event of an interruption in a primary source of power that otherwise provides power to; and control means for turning the lamp on utilizing the backup source of power when there is an interruption in the primary source of power.
Claim 12
Independent Claim 148 words
A system, comprising: a case having a size and shape adapted to house a power supply unit and be supported atop a conventional personal computer that is supported above a keyboard; a forward portion of the case adapted to overhang the personal computer; at least one lamp mounted on a lower portion of the forward portion in a position such that a substantial portion of light emanating from the lamp is directed downwardly toward the keyboard when the lamp is turned on; a power supply unit substantially within the case that is adapted to provide power to the computer from a separate backup source of power in the event of an interruption in a primary source of power that otherwise provides power to; and control means for turning the lamp on utilizing the backup source of power when there is an interruption in the primary source of power.
