Abstract: A wireless wearable Push-To-Talk (PTT) device is disclosed which is capable of enabling three or more short-range communication accessories. In specific, the wearable Push-To-Talk device can be connected to multiple short-range communication accessories such as a hearing accessory, a visual accessory and a wearable Push-To-Talk control accessory through a heterogeneous communication unit provided therein. A Bluetooth radio transceiver and a cellular radio transceiver are configured in said heterogeneous communication unit to transmit or receive radio signals. The heterogeneous communication unit supports the Bluetooth communication between the Push-To-Talk system and other short-range communication accessories either simultaneously or individually. The Push-To-Talk device along with multiple short-range communication accessories assists the operator with an efficient and secured communication.

Abstract: The present invention proposes a multi-featured miniature camera. The components of the camera mainly comprise of an image capturing means, multiple activating means, an infrared radiating means, a microphone, multiple Bluetooth connection means, an identification chip means, a wireless power charging means, a wireless data transfer means, an image processing means and a location determination means. The camera provides wireless power and data transfer, image recognition, Push-To-Talk (PTT) function, multiple Bluetooth communication etc. This multi-featured camera is mounted on different application areas such as on the helmet of police officers, sport players, firefighters etc. The camera body is designed in such a way, that it easily fits on the helmet.
