Video processing unit for a visual prosthetic apparatus
First Claim
1. A video processing unit configured for communication with an implantable visual prosthesis and further configured to convert a video image to stimulation patterns for stimulating visual neural tissue and comprising a power button and other buttons and an indicator light, wherein the video processing unit is configured to be powered on and provide a first user notification to a patient after the power button is continuously activated for a first predetermined time interval, wherein the video processing unit is configured to be powered off and provide a second user notification to the user different from said first notification after the power button is continuously activated for a second predetermined time interval upon activation of the power button, and wherein the power button is differently shaped than the other buttons, and wherein the indicator light provides different signals to indicate the first predetermined interval, the second predetermined interval, a normal operation mode and an error mode, wherein when the error mode is activated the video processing unit will shut down automatically.

6. A method for providing artificial vision for use with an implantable visual prosthesis configured to communicate with a video processing unit, the method comprising:
- identifying a power button on the video processing unit by identifying a different outermost surface parallel to the direction of activation, powering on the video processing unit and providing a first user notification to a patient after the power button is continuously activated for a first predetermined amount of time, capturing a video image;
converting the video image to stimulation patterns for the implantable visual prosthesis using the video processing unit, stimulating neural tissue in the patient'"'"'s eye based on the stimulation patterns, and providing a second user notification to the patient, different from the first notification, to indicate an error mode wherein when the error mode is activated the video processing unit will shut down automatically. - View Dependent Claims (7, 8, 9)
