Embodiment Construction

[0027] joint reference figure 1 with figure 2 , shows a system 100 for SAR testing a mobile communication device 150 . System 100 includes suitably programmed measurement controller / processor 105 , computer system 110 and positioning system 115 , and includes probe 120 , receiver 125 , communication unit 130 , simulated hand 160 and simulated head 170 . Measurement controller 105 communicates with probe positioning system 115 to place probes 120 in a series of spaced locations within the simulated head and in relation to mobile communication device 150 .

[0028] Probe positioning system 115 may be a robotic arm adapted to precisely move and position probe tip 128 (see figure 2 ).

[0029] One example of measurement controller 105 is the commercially available DASY4 system sold by Schmid & Partner Engineering AG. The system includes suitable software for performing the SAR test, including controlling the detector positioning system 115 , as well as suitable devices to ac...

Abstract

Embodiments relate to systems and methods for conducting specific absorption rate testing of a mobile communication device. A system includes: a simulated head; a simulated hand positioned proximate to the simulated head for supporting the mobile communication device during the testing; a probe positioned within the simulated head; and a processor. The processor is operatively coupled to the probe and configured to determine a field strength of a field radiated by the mobile communication device. A method includes: positioning the mobile communication device in supported relation to a simulated hand; causing a probe to be positioned within a simulated head, the simulated head positioned in proximity to the mobile communication device; and determining a field strength of a field radiated by the mobile communication device.

Description

technical field [0001] The described embodiments generally relate to methods and systems for Specific Absorption Rate (SAR) testing of mobile communication devices. Specifically, the method and system relate to using a simulated hand to support a mobile communication device during testing. Background technique [0002] Government safety standards strictly regulate the field strength of mobile communication equipment. The regulations specify a specific allowable absorption rate, that is, a safe amount of radio frequency energy that a person can safely withstand. Manufacturers must ensure their devices meet such standards; the regulations also specify testing requirements and processes to be used before new models are approved for public use. [0003] In order to meet the test requirements, the test results must be repeatable. Measurements obtained during SAR testing have a certain amount of inherent uncertainty. Accordingly, regulations specify that the uncertainty of the...
