Abstract
A visual feedback system for providing information to a user regarding aspects such as the status and operation of the systems and components of one or more electronic devices. The visual feedback system is preferably employed in the context of a PC card and includes one or more light sources, preferably light emitting diodes, configured for electrical communication with the electronic circuitry by which the functionality of the PC card is implemented so that certain events that occur with respect to the status and operation of the PC card cause the light source to emit light. The emitted light is received by a light reflecting member that, preferably, substantially encloses the light source and reflects the received light in a manner and form consistent with a desired application. The reflected light is then directed, by virtue of the geometry of the light reflecting member, to one or more predetermined locations, one of which is preferably proximate to the receptacle of a connector included in the PC card. Thus, light emitted by the light source is correlated with operations performed by, and/or in conjunction with the PC card, and is then directed to a location visible to a user…
