Abstract: It is proposed to have the IFFT size information exchanged during the initialization of the modems. For a number of reasons different vendors may decide to generate the transmit signal (either the U/S or the D/S) through IFFT sizes greater than the ones specified by the Standard. Letting the receiver know the IFFT size of the transmitter can guarantee inter-performance between different pairs of modem. The receiver could in fact adapt its FFT size to match the IFFT size in the transmitter.

Title: Method and system for reducing the volume of audit data and normalizing the audit data received from heterogeneous sources
Inventor: WALKER JEFFREY H
IPC: G06F1/00
Filed: 1999-06-02
Abstract: A method of reducing the volume of native audit data from further analysis by a misuse and intrusion detection engine is disclosed. Typically, more than ninety percent of the volume of audit information received from heterogeneous operating systems does not need to be analyzed by a misuse and intrusion detection engine because this audit information can be filtered out as not posing a security threat. Advantageously, by reducing (eliminating) the volume of audit information, a misuse and intrusion engine can more quickly determine whether a security threat exists because the volume of data that the engine must consider is drastically reduced. Also, advantageously, the audit information that is forwarded to the engine is normalized to a standard format, thereby reducing the computational requirements of the engine. The method of reducing the volume of native audit data includes comparing each of the native audits against at least one template and against at least one native audit. By matching the native audits against templates of native audits that do not pose security threats, the native audits that do not pose security threats can be reduced out from further consideration. The native audits that are determined to pose potential security threats are transformed into a standardized format for further analysis by a misuse and intrusion detection engine.

Patent CA-2338042-A1 (CA)
Inventor: DUTT BIRENDRA
IPC: H04B10/118
Filed: 2000-03-22
Abstract: An optical CDMA system is implemented at least partially within a photonic integrated circuit. A broad-spectrum light source is modulated with data to be transmitted. The light source is spatially dispersed, for example using a diffraction grating, and passed through a spatial spectrum-coding mask embodied within the photonic integrated circuit. The dispersed frequencies of the encoded modulated light beam are then recombined to provide a modulated, encoded spread spectrum optical signal for injection into an optical fiber or another optical communication system. Received light is split into two components and provided to a pair of complementary decoders. Within each of the complementary encoders, the received portion of the light beam is spatially dispersed and passed through a spatial decoding mask. Both the dispersion element and the mask are embodied within the photonic integrated circuit. One of the decoders includes a spatial decoding mask that embodies the spatial encoding function U of the original transmitting mask and the other, complementary decoder includes a complementary function U*. Within each of the complementary decoders the spatially spread light signals are recombined after passing through the decoding masks. The signals passing through the complementary decoding masks are then provided to different inputs of a differential detector and the data originally modulated within the light is recovered.

Title: Protective recombinant haemophilus influenzae high molecular weight proteins
Inventor: LOOSMORE SHEENA M
IPC: C07K14/285
Filed: 1999-10-07
Abstract: Protective high molecular weight (HMW) proteins are produced recombinantly b y expression from E. coli by using a promoter effective in E. coli and a nucle ic acid molecule which contains a modified operon of a non-typeable strain of Haemophilus. The modified operon contains the portion only of the A region which encodes the mature HMW protein and the complete B and C regions of the  operon. Enhanced levels of expression of the HMW proteins can be achieved by  including the E. coli cer gene, a further copy of the portion of the A regio n of the operon encoding the mature protein or both, in the expression vector.  Nucleotide and deduced amino acid sequences of the hmw1 and hmw2 genes and HMW1 and HMW2 proteins, respectively, of several non-typeable Haemophilus influenzae strain have been identified.
