Title: Television capable of downloading WML data
Inventor: SANSOM PATRICK
IPC: G06F17/30
Filed: 2001-01-12
Abstract: There is provided a television receiver which comprises a browser for accessing a web site via the internet. The television receiver is arranged to download data represented by the Wireless Markup Language (WML). The television receiver processes the data to output a signal representative of an interactive television image allowing user interaction with the web site via a remote control. The television receiver supports an extended WML Document Type Defintion (DTD) which provides for the representation of additional layout and functional attributes pertaining to the interactive image. The layout of the interactive image is determined by metalevel information contained in broadcast television signals. Services from the interactive image can be selected by entering a set of numbers via the numeric keyboard on the remote control, wherein each of the numeric keys of the numeric keys is associated with a number of letters such that the set of numbers to be entered corresponds to a keyword descriptive of the service to be seletced. There is also provided an on-line server for connecting the television receiver with the web site. The server is arranged to perform authentication, authorisation, compilation, pre-processing and decryption/encryption as part of the connection process.

Title: Transmit / receive antenna system with higher receive gain
Inventor: DODD ALEXANDER
IPC: H04B1/48
Filed: 2001-04-06
Abstract: An antenna system, having application to low power license exempt wireless local area networks (WLAN), such as Bluetooth and IEEE 802.11A. The system has a first antenna 15 for transmitting and a second antenna 16 for receiving, the second antenna having higher gain than the first. A signal detector 18 may be provided which causes a transmit/receive switch 13 to operate. The effective isotropic radiated power output (EIRP) of the first antenna is preferably less than 100 mW. Alternatively, a common antenna may be used for both receiving and transmitting. In this case an attenuator limits the power of the transmission, but not the reception. Also disclosed is an apparatus for electromagnetically coupling an external antenna to an existing wireless device having an integrated antenna.

Title: Space time coded data transmission via inductive effect between adjacent power lines
Inventor: HONARY BAHRAM
IPC: H04B3/54
Filed: 2001-12-15
Abstract: Space time coded data is transmitted via electricity mains by sending data encoded with some redundancy ("time diversity") from one modem down one conducting line which interacts inductively with adjacent conducting lines to provide further replication of itself ("space diversity"). The effects of induction on parallel conductors will cause all receiving modems to receive some of the signal, necessitating an identifier (<I>eg</I>. header) of the intended recipient to form part of the signal. A handshake procedure employing test signals is used to establish the nonlinearity of the frequency response and time domain response of the link, and appropriate coding and selected combinations of frequency channels and time slots involving different conducting lines are chosen to optimise communication (fig 3), thus providing diversity in an analogous manner to mobile telephone communication via multiple antennas. A filter is used to minimise "mains hum", <I>ie</I>. signals at electricity supply frequencies.

Title: One-cylinder stack capacitor
Inventor: OH JUNG-HWAN
IPC: H01L21/8242
Filed: 2002-11-27
Abstract: An etch stop layer 120 is formed over a surface of an interlayer insulating layer 100 and over a surface of a conductive plug 115 extending at a depth from the surface of the interlayer insulating layer. A lower mold layer 130 is deposited over the etch stop layer, and a wet etch rate of the lower mold layer is adjusted by adding dopants to the lower mold layer during formation of the lower mold layer, and by annealing the lower mold layer. An upper mold layer 135 is then deposited over the surface of the lower mold layer, such that a wet etch rate of the upper mold layer is less than the adjusted wet etch rate of the lower mold layer. The upper mold layer, the lower mold layer and the etch stop layer are then subjected to dry etching to form an opening therein which exposes at least a portion of the surface of the contact plug. Then a wet etching of the upper mold layer and the lower mold layer is performed so as to increase a size of the opening at the lower mold layer and so at to expose a surface portion of the etch stop layer adjacent the surface of the conductive plug. A conductive material 150 is then deposited over the surface of the opening in the upper and lower mold layers to define a capacitor electrode, eg for a DRAM.

Title: Identifier-based encryption
Inventor: CHEN LIQUN
IPC: H04L9/30
Filed: 2003-05-22
Abstract: First data to be sent by a sender first party (20) to a recipient second party (30) is encrypted using an encryption key formed using at least a hash value generated using second data and a secret, shared with a trusted party (40), that serves as identification of the sender (20). The second data comprises, for example, one or more conditions that serve as identifiers of the recipient (30), and a hash-value element generated by hashing the first data. The encrypted first data and the encryption key is made available to the recipient (20) which forwards the encryption key to the trusted party (40) with a request for the corresponding decryption key to enable decryption of the received data by the recipient. The trusted party (40) carries out at least one check on the basis of data contained in the encryption key and, if this at least one check is satisfactory, provides a decryption key to the second party. The shared secret may be the private key generated by the trusted party, of a public/private key pair associated with the sender. In another embodiment the shared secret may be a symmetric key. The encryption process effected may be an identifier-based cryptographic process utilising quadratic residuosity or Weil or Tate pairings.

Title: One stage OFDM de-interleaver using a single memory
Inventor: FENG CHIH-CHUN
IPC: H03M13/27
Filed: 2003-09-29
Abstract: An apparatus and method having a de-interleaving memory and a controller is used for de-interleaving interleaved data in a coded orthogonal frequency division multiplexing receiver. The controller generates the correct access addresses of the de-interleaving memory for the data to be de-interleaved, and controls the read and write operations to the de-interleaving memory. The controller comprises an address generator having a plurality of base address generators, and a read/write control circuitry. By using the de-interleaving memory combined with memory address computation for the interleaved data, frequency de-interleaving, block de-interleaving and time de-interleaving are performed in one-stage approach in the COFDM receiver. The memory size is reduced and the circuitry complexity for performing the de-interleaving process is relatively low.
