Abstract: The present invention relates to a communication system for a helmet, comprising a docking station located in the rear portion of said helmet, and a detachable portion adapted to be connected to said helmet via said docking station, wherein said detachable portion comprises pressure-activated elements, which are located at a distance from the center of the rear portion of said helmet, such as to be easily reached by the fingers of the wearer.

Abstract: A user interface device for applying control signals to a communication system, comprising: at least one pressure-activated multidirectional tiltable/pushable plate with multiple pressureable areas, wherein each of said pressureable areas activates a corresponding pressure element that is located under said plate, wherein each activation of a specific pressure element defines an action which is respectively performed upon tilting-pressing of said plate towards the location of the respective pressure element.

Abstract: The present invention relates to a method of extending an intercom communication range, comprising: a) during the pairing process between a first headset communication device and a second headset communication device, providing cellular related parameters, to be stored in a memory module of each headset communication device, in addition to the common Bluetooth required parameters, such that the cellular related parameters of the first headset includes a cellular phone number associated with the second headset and vice versa; b) establishing an intercom communication between both headsets via a Bluetooth channel; and c) upon detecting intercom communication loss at said Bluetooth channel or unavailable Bluetooth link during said intercom communication, temporarily routing the intercom communication to an alternate cellular communication channel by initiating a cellular call using the stored cellular phone number of the second headset.
