## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. utility application entitled, “Rechargeable universal remote control assembly,” having Ser. No. 11/786,801 and original filing date of Nov. 15, 2002, and issued as U.S. Pat. No. RE42613, “Rechargeable universal remote control assembly,” having Ser. No. 10/295,627, filed on Nov. 15, 2002 and issued as U.S. Pat. No. 6,879,254, all of which are entirely incorporated herein by reference.


BACKGROUND
The use of universal remote controls is known in the prior art. U.S. Pat. No. 4,718,112 describes a remote control apparatus for programming a series of control commands for use at a later time. Another type of universal remote controls is U.S. Pat. No. 5,953,144 having a ROM-less microprocessor system. U.S. Pat. No. 5,790,021 discloses a remote control having a base unit and a remote control finder. U.S. Pat. No. 3,582,783 discloses a multiple function remote control unit. U.S. Pat. No. 5,412,377 also discloses a remote control unit that has a scheduling function. U.S. Pat. No. Des. 435,544 shows an ornamental design for a universal remote control.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a remote control system that will provide commands for multiple and various devices in combination with a base unit for recharging the remote control, a remote control finding function, and wherein the remote control has a light for outlining the housing of the remote control.

DETAILED DESCRIPTION
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new rechargeable universal remote control assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the rechargeable universal remote control assembly 10 generally comprises a base unit 20 having a charging port 22 and a remote control unit 30 having a battery 32. The remote control unit 30 is positionable on the base unit 20 such that the remote control unit 30 operationally engages the charging port 22. Thus, the base unit 20 charges the battery 32 of the remote control unit 30.
A transmitter 24 is positioned in the base unit 20 for transmitting a locate signal. A receiver 34 is positioned in the remote control unit 30 for receiving the locate signal from the transmitter 24.
A microprocessor 36 is positioned in the remote control unit 30. The receiver 34 is operationally coupled to the microprocessor 36. A speaker 38 is operationally coupled to the microprocessor 36 for producing an audio signal from the remote control unit 30 when the receiver 34 receives the locate signal from the transmitter 24.
A light source 40 is operationally coupled to the microprocessor 36 for illuminating when the receiver 34 receives the locate signal from the transmitter 24. The light source 40 is a tubular light extending around a perimeter 31 of the remote control unit 30.
An infrared transmitter 42 is operationally coupled to the microprocessor 36 for sending operational commands from the remote control unit 30 based on use of a plurality of operational keys 44. Each of the operational keys 44 is operationally coupled to the microprocessor 36 for sending a selectable operational command from the remote control unit 30 using the operational keys 44. The operational keys are configured into groups for controlling particular devices including TV, VCR, DVD, stereo and video receivers, satellite receivers, and audio equipment. The remote control unit may further include operational keys and programs to operate other household devices such as ceiling fans or appliances remotely using the remote control unit 30.
A plurality of indicator lights 46 are positioned on the base unit 20. One of the indicator lights is a positive charging light 48. The positive charging light 48 illuminates when the remote control unit 30 engages the charging port 22 of the base unit 20 to successfully charge the battery 32 of the remote control unit 30. A second one of the indicator lights is a negative charging light 50. The negative charging light 50 illuminates when the remote control unit 30 is disengaged from the charging port 22 of the base unit 20.
The remote control unit 30 has a plurality of battery charge indicators 52 operationally coupled to the battery 32 for indicating a charge level of the battery 32. In an embodiment, the battery charge indicators 52 are aligned next to each other and illuminate in sequence such that a number of illuminated battery charge indicators indicates a degree to which the battery 32 is charged.
The remote control unit 30 has a housing 33 having a bulbous forward portion 35, a neck portion 37, and a rear portion 39. The base unit 20 has a depression 25 for receiving the remote control unit 30. The depression 25 has a complementary shape to the remote control unit 30 to prevent movement of the remote control unit 30 within the depression 25.
In use, the remote control unit is placed into the depression of the base unit to charge the remote control unit. The remote control unit is used in similar fashion to existing remote controls to operate a variety of devices. When removed from the base unit, the remote control unit can be located easily by pressing a button on the base unit. In response to the button on the base unit being pressed, the remote control unit provides an audio signal via a speaker and a visual signal via the light source extending around the perimeter of the remote control unit.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
