Abstract
A proximity sensor system for use with mobile communication devices that reduces the incidence of false positives. The proximity sensor system includes a first sensor and a second sensor, each of which are configured to separately generate outputs indicative if the mobile communication device should operate in a handset mode or a speakerphone mode. The system further includes a processor configured to switch the operation of the mobile communication device between the handset mode and the speakerphone mode when both outputs indicate that the mobile communication device should be in one mode or the other. By relying on both first and second sensors, the incidence of false positives is reduced. In various alternative embodiments, multiple first sensors and/or second sensors may be used.
