11. A method comprising sensing a biological rate with a cellular phone, positioning a camera on the cellular phone in contact with or near a body part and sensing light variations on the camera, providing time intervals from a clock in the cellular phone, comparing the sensed light variations and the time intervals provided by the clock in the cellular phone and indicating a biological rate with one or more numeric display, graphic display, spoken words, audible alarm, visual alarm and remote reporting.

12. Biological rate sensor apparatus comprising:
-
a consumer electronic device having a camera sensing periodic light variations through or near a body part, a clock providing time periods, a comparator connected to the camera and clock comparing the light variations sensed by the camera with the time periods provided by the clock and providing a rate of light variations, an indicator connected to the comparator indicating results of the providing a rate of light variations as a biological rate. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
