Determining proximity of transmitter antennas of portable devices to a human body for limiting transmitter output power to meet specific absorption rate (SAR) requirements

A system, comprising:

• a transmitting device configured to determine whether a transmitting power of the transmitting device is to be adjusted based at least in part upon a state of an antenna of the transmitting device at least by further configure the transmitting device to perform a set of acts that comprises:
• receiving image data from an image capturing system physically separate from the transmitting device;
• and
• determining whether the transmitting device is proximate to a human body or a portion thereof by performing one or more analyses on the image data captured by the image capturing system;
• and
• determining, at the transmitting device, whether the transmitting power of the transmitting device is to be adjusted based at least in part upon a result of determining whether the transmitting device is proximate to the human body or the portion thereof.

A transmitting device, comprising:

• an antenna configured to transmit signals at a transmitting power, wherein the transmitting power is adjustable;
• a processor operatively coupled to the antenna;
• a memory storing thereupon a set of instructions which, when executed by the processor, causes the processor at least to:
• determine whether to adjust the transmitting power based at least in part upon a state of the antenna at least by performing, by the processor, a set of acts that comprises:
• receiving image data from an image capturing system physically separate from the transmitting device;
• and
• determining whether the transmitting device is proximate to a human body or a portion thereof by performing one or more analyses on the image data captured by the image capturing system;
• and
• determine whether the transmitting power is to be adjusted based at least in part upon a result of determining whether the transmitting device is proximate to the human body or the portion thereof.
