Claim Text:
1. A method, implemented by a user device programmed to perform the following, the method comprising: transmitting first data at a specified transmit power level using an antenna of the user device; receiving a first measurement from a first proximity sensor pad, wherein the first measurement is indicative of a first distance between the first proximity sensor pad and an object; receiving a second measurement from a second proximity sensor pad, wherein the second measurement is indicative of a second distance between the second proximity sensor pad and the object; receiving a third measurement from a third proximity sensor pad, wherein the third measurement is indicative of a third distance between the second proximity sensor pad and the object, wherein the first proximity sensor pad is located adjacent to a first end of the antenna, the second proximity sensor pad is located at an approximate center location of the antenna and adjacent to a longitudinal side of the antenna and the third proximity sensor pad is located adjacent to a second end of the antenna; determining a triggered state for reducing the specified transmit power level to a reduced transmit power level used by the antenna when any one of four proximity test conditions is met using the first measurement, second measurement and third measurement, wherein the four proximity test conditions are—defined by different combinations of distance thresholds for the first measurement, second measurement and third measurement, wherein the different combination of distance thresholds define distances of the object relative to the antenna, wherein at least one of the four proximity test conditions is met when the first measurement exceeds a first threshold and a ratio of the second measurement and the first measurement is less than a third threshold; and in response to the triggered state, transmitting second data at the reduced transmit power level.
