Abstract:
The present invention relates to a method for chlorination of silver materials in the forms of wire, thick film paste and metallic sheet/disc. The method is environmentally friendly since the process does not produce hazardous chemicals or flammable gas. The electrochemical setup includes position the electrode containing silver materials in the anode and a platinum wire at the cathode. A DC voltage supply between 1 to 5 volts oxidizes the silver surface which receives chloride from imidazolium chloride solution to produce silver chloride on silver wire, film or disc. The imidazolium chloride reagent can be in aqueous solution or polar organic solvents or naturally exists in ionic liquid form. The imidazolium radical cation decomposes to produce a stabilized organic radical and an imidazole molecule. The stabilized radical recombines to produce volatile organic compound that can be recovered by simple distillation. The chlorination reagent can be regenerated by re-introducing the stabilized group at N 1 .
Abstract:
A method (200) and system (100) for encapsulating multicast packets into unicast packets, the system comprises a TCP/TP communication stack having means for receiving a plurality of incoming multicast packets from an incoming wireless module (102), a first translation module (106) having means for translating the plurality of incoming multicast packets to a recognizable format for mapping, an intelligent hashing table (110) comprises means for storing a extracted subscriber IP address, a subscriber MAC address and a TTL period, a second translation module (114) comprises means for translating the unicast packets to a format recognizable for transmission, means for transmitting the unicast packets into an outgoing wireless module (116) and mapping modules comprises of a first mapping module (108) and a second mapping module (112). The mapping modules (108, 112) comprises the method of extracting the subscriber IP address, the subscriber MAC address and the TTL period from a plurality of incoming multicast packets (302), storing the subscriber IP address, the subscriber MAC address and the TTL period in an intelligent hashing table (304); encapsulating the plurality of incoming multicast packets into a plurality of unicast packets (306), forwarding the unicast packets for mapping (308) and multiplying the unicast packets in the presence of multiple subscribers (310).
Abstract:
The present invention discloses a method and system for providing or ensuring synchronization of cryptographic devices for transmission of data within a voice channel, particularly the GSM voice channel network. The transmission source (100) is configured to generate several cycles of 32-bit digital zeros data prior to transmitting the encrypted data to the reception source (200). Accordingly, the transmission of digital zeros data provides sufficient time for the reception source (200) to prepare for receiving the encrypted data from the transmission source (100) and thereby assisting in synchronization of devices initialization for data transmission.
Abstract:
A system for communication in a wireless backhaul environment having wireless mesh networks connected in part to the Internet comprising a communication topology. The communication topology comprises communication cells each having a relay station and mobile nodes communicating to each other using 802.16j wireless technology wherein the cells are arranged in a grid fabric within the communication topology.
Abstract:
An apparatus for solar tracking using minimal energy is described. A prismatic energy harvester (10) is positioned above a spring (20). The harvester has a pair of ears (14) at both side of the top portion of the harvester. The ear is moved by strings (16) from a reel (18) connected to a box of motor (12). At least two photo-resistive elements track the sun rays intensity to identify the position of the sun. Then, the motor adjust the reels to rotate the harvester using strings until the harvester and the sun is at right angle. The photo-resistive elements continuously track the sun so that the harvester can be rotated towards the sun at right angle.
