DETAILED DESCRIPTION

[0011] The invention is further described in detail referencing figures illustrating the systematic arrangement for ICDS interacting with an image capturing device associated with, or not associated with, a handheld wireless communication device.

[0012] Fig. 1 depicts an exemplary visual diagram of a ICDS, according to a first embodiment of the present inventions, h Fig. 1, the main image capture detection system 100 is monitoring the handheld wireless communication device with or without image capturing device 104. The main image capture detection system 100 can be hard wired or wirelessly connected to viewer/monitoring client 109. The control antennas 102 are hard wired 101 to the main image capture detection system 100. The control antenna 102 monitors the image capturing device 104 with or without handheld wireless communication device using radio frequency/Bluetooth/WLan protocols 103.

[0013] The signal beam 103 may cover no more than a predefined area. The signals beam 103 intercepts the image capturing device with or without handheld wireless communication device 104 through, a port 106 such as on the handheld wireless communication device 104. The port 106 may correspond to a WLAN or a Bluetooth or an IR port, where a WLAN system covers a diameter from 3 blocks to 30 miles, a blue tooth system covers a diameter range of around 330 feet and an "IrDA" infrared red system covers less than 5-10 feet in a direct line of sight.

[0014] WLan/Bluetooth/IR communication ports may be made available on most of the currently available handheld wireless communicating devices such as, without limitation, image capturing devices with or without cellular phones, PDA's, voice communicating PDA's and mobile PC's. Since many of the current and planned hand-held devices may be needed for performing a variety of other functions, such WLan/Bluetooth /IR ports on image capturing device with or without the handheld communication devices according to this invention would remain available for such other functions as well.

[0015] Fig. 2 depicts an exemplary breakaway of ICDS with an arrangement to ensure secure and safe communications according to a second embodiment of the present invention. In this embodiment, the main image capture detection system 100 is implemented at the operations center. The control antennas 102 are installed at regular intervals along the boundary of the restricted or prohibited zone. The main image capture detection system 100 consists of 9 major components: system bus 110, display unit 111, communication unit 112, storage device 113, auxiliary device 114, connectors 115, user interface 116, main controller

117, memory (RAM/ROM) 118, and system Application 119.

[0016] The main controller 117 is interfaced with a communication unit 112, a display unit 111, a auxiliary device 114 and user interface 116 which are shared by the same system bus 110. The system is mounted with a system application 119, which is stored on memory

118. An extra physical storage 113 and a set of connectors 115 are provided for further expansion.

[0017] The communication unit 112 comes mounted with a processor, a signal regulator, a transceiver adapter and a signal modulator/de-modulator.

[0018] Fig. 3 exemplary flow diagram of an image capturing device with or without the handheld wireless communication device according to a third embodiment of the present invention. In this embodiment, the image capture device 121 is connected to the user interface module 122. The device has an onboard central processing unit 125 and is interconnected to the various sub-components via a system bus 120. The system application runs on the processor 125 and provides control and coordinates the functions of the various components of the system. The system application is stored in Memory 124 which increases the overall performance of the communication system. The external storage 123 is provided where the sub-application components reside. The communication unit 126 is connected to receiver 127 and transmitter 128. The device is fully equipped with a display panel 131, a communication (I/O) port 130 and a signal enhancing antenna 129.

[0019] The I/O port may correspond to a RF, WLAN IEEE 802.1 lx & 802.16x standards, Bluetooth or an IR port, where the wireless 802. l lx covers the area of about 3 block, the wireless 802.16x covers the area of about 30 miles, a blue tooth system covers a diameter range of approximately 330 feet and an "IrDA" infrared red system generally covers less than 5-10 feet in a direct line of sight. This technology as is described in greater detail below.

[0020] The Bluetooth wireless specification includes both link layer and application layer definitions for product developers which supports data, voice, and content-centric applications. Handheld wireless communication devices that comply with the Bluetooth wireless specification operate in the unlicensed, 2.4 GHz radio spectrum ensuring communication compatibility worldwide. These radios use a spread spectrum, frequency hopping, full-duplex signal at up to 1600 hops/sec. The signal hops among 79 frequencies at 1 MHz intervals to give a high degree of interference immunity. Up to seven simultaneous comiections can be established and maintained. Further details can be viewed at www.bluetooth.org or www.bluetooth.com.

[0021] The IrDA specifications, on the other hand, is intended for high speed short range, line of sight, point-to-point cordless data transfer - suitable for handheld communication devices. Since 1984, "IrDA Data" defines a standard for an interoperable universal two way cordless infrared light transmission data port. IrDA technology is already in over 300 million electronic devices including PC's, PDA's, cellular phones, cameras, toys, watches and many other mobile devices. Main characteristics of IrDA signaling include:

• Range: Continuous operation between two contacts for at least 1 meter.

• Bi-directional communication is the basis of all specifications.

• Data transmission starting from 9600 kbps primary speed going up to 4.0 mbps.

• Data packets are protected using CRC (from CRC 16 for speeds up to 1.152 mbps to CRC-32 at 4.0 mbps)

[0022] Radio waves are created due to the movement of electrical charges in antennas. As they are created, these waves radiate away from the antenna. All electromagnetic waves travel at the speed of light. The major differences between the different types of waves are the distances covered by one cycle of the wave and the number of waves that pass a certain point during a set time period. The wavelength is the distance covered by one cycle of a wave. The frequency is the number of waves passing a given point in one second. For any electromagnetic wave, the wavelength multiplied by the frequency equals the speed of light. The frequency of an RF signal is usually expressed in units called hertz (Hz). One Hz equals one wave per second. One kilohertz (kHz) equals one thousand waves per second, one megahertz (MHz) equals one million waves per second, and one gigahertz (GHz) equals one billion waves per second.

[0023] RF energy includes waves with frequencies ranging from about 3000 waves per second (3 kHz) to 300 billion waves per second (300 GHz). Microwaves are a subset of radio waves that have frequencies ranging from around 300 million waves per second (300 MHz) to three billion waves per second (3 GHz).

[0024] Basically WLAN is an ordinary LAN protocol, which is a modulated carrier of radio frequency waves. WLAN IEEE 801.11 is a natural extension to LAN Ethernet, and the modulated protocol is IEEE 802.3 (Ethernet 3).

[0025] Common WLAN Products, which are using IEEE standards, are based on IEEE 802.11 and 802.11b specification. 802.11b is a high rate extension to the original 802.11, and specific 5.5 to 11 Mbps data rate. The next HyperLAN2 generation using IEEE 802.11a, IEEE 802.1 lg standards, operates in a new band frequency of 5 GHz, and achieves a high data rate as 54 Mbps. The new networking technology WiMax IEEE 802.16x should provide higher speed, and more coverage than existing Wi-Fi standards.

[0026] Fig. 4 depicts an exemplary flow diagram of activation of surveillance mechanism and deactivation of the image capturing device by ICDS in at least one embodiment of the present invention. The main image capturing device detection system scans the area for all the operational image capturing device (whether associated with or not associated with a handheld wireless communication devices) - step 142. If there is no activity on the network, the system continues scanning for the operational image capturing device (associated with or not associated with a handheld wireless communication device) - step 143. If found, the system scans for the active profile on the image capturing device (with or without the handheld wireless communication device) - step 144.

[0027] The system scans for the "silent" profile on the handheld wireless communication device - step 146. If the "silent" profile is not active, the ICDS system activates the "silent" profile on the handheld wireless communication device - step 145. If the handheld wireless communication device is on the "silent" profile, the ICDS system scans the handheld wireless communication device for any active image capturing application - step

148. If there is any image capturing application 147 is activated on the handheld wireless communication device, the ICDS system deactivates the image capturing application - step

149. The ICDS system registers the user in the database - step 150. On successful completion of the transaction, the entire event is logged in the database - step 151, following which ICDS system resets itself on to a scan mode - step 143.

[0028] Fig. 5 depicts an exemplary flow diagram of restoration of the system application to a default setting by ICDS in at least one embodiment of the present invention. The main image capturing device detection system actively scans the area for all operational image capturing devices with or without the handheld wireless communication devices. If the user moves the image capturing device with or without the handheld wireless communication device out of the active zone - step 161, the ICDS system scans and matches the registered user with the database - step 162. If the register user identification data is found, the ICDS system checks for the active profile - step 163. If the active mode is in a "silent" profile the pre-existing profile is restored to the device and the "silent" profile is deactivated - step 165.

, [0029] The ICDS system checks if the image capturing application is deactivated - step 166. If the image capturing application is deactivated, ICDS system restores the image capturing application to the active mode - step 167. The restored settings are once again confirmed with the database - step 168. The ICDS system modifies the database - step 169 and returns to its scan mode.
