LED Flashlight on a Handheld Device

Disclosed is a method that places a low-power, bright LED light on a PDA device so that it can be used as a notification light or a flashlight. Benefits include expanding the usefulness of PDA devices.

Background

Currently, new low-power LED lights are not used within PDA devices; however, there is an industry-wide desire to explore further uses for PDA devices.

General Description

The disclosed method places a low-power, bright LED light on a PDA device so that it can be used as a flashlight. The LED light is powered by the same battery as the rest of the PDA, and controlled by a separate button on the side of the device. Both the standard buttons on the PDA and the built-in software control the LED light.

The disclosed method can be used as a visual cure to notify a user of incoming messages, meeting events, or other events; it can also be used by people with hearing impairments as a way to get notifications from their hand held device. In addition, the light can be seen up to one mile away, and may be used as a flashlight or to communicate information (via Morse code) over long distances.

Advantages

Some implementations of the disclosed structure and method provide one or more of the following advantages:

The disclosed method enables new PDA functionality, including a message indicator and a low-power bright LED flashlight.
