Title: Protection switching architecture and method of use
Inventor: KERFOOT FRANKLIN W III
IPC: H04J14/00
Filed: 2004-01-21
Abstract: A protection switching architecture is used in a telecommunications system such as a wavelength division multiplexed (WDM) telecommunications system to replace a failed transmission line or a failed wavelength processing device. A spare wavelength processing device transmitter replaces a failed service wavelength processing device transmitter. A spare transmission line replaces a failed service transmission line. A spare wavelength processing device receiver monitors the optical signals, one wavelength at a time, on either the spare transmission line or the service transmission line and replaces one of the service wavelength processing device receivers. Wavelength selection equipment routes either the service transmission line or the service transmission line to the service wavelength processing device receivers and selects wavelengths to be monitored by the spare wavelength processing device receiver.

Title: Hydroelectric power plant producing electricity from potential energy of liquids in power plants on boats or on ground using small basin or pressurized in shallow water
Inventor: ABOU-RAPHAEL AFIF
IPC: F03B17/02
Filed: 2004-03-16
Abstract: This invention relates to the construction of power plants of the type described in the Canadian patent no 2328580. Each of these plants is placed in a shallow pressurised pool. A number of these plants are connected together with the same pneumatic circuit, in order to use the same flow of compressed gas that enters in the first power plant and exits from the last one of the same series while producing growing energy with the same volume of gas that expends at shallower depth and displaces more liquid for a bigger buoyant force. These pressurized pools when connected together they give conditions of deep depths that permits the transformation of almost all of the potential energy of compressed gases at any pressure. In addition, these pools can be built on the surface, or in recycled ships where the transformation of compressed air produced by compressors, using the abundant and renewable energy of the sea waves is possible.

Title: Method and apparatus for secure key management using multi-threshold secret sharing
Inventor: NADOOSHAN MEHRDAD
IPC: H04L9/08
Filed: 2002-09-19
Abstract: A method and apparatus are disclosed for managing components of a secret key according to a secret sharing scheme. The disclosed secret sharing scheme divides a secret value, R, into n secret components (Rl, R2, ..., Rn) and one super component, S, in such a way that R can be computed from (i) any k or more Ri components (k < n); or (ii) S and anyone component of Ri. The secret components (Rl, R2, ..., Rn) are distributed to a number of authorized users. A multiple threshold secret sharing scheme assigns various users in a group into one of a number of classes. Each user class has a corresponding threshold level that indicates the number of users that must come together with their assigned components to obtain access to the shared secret. The multiple threshold scheme divides the secret into n components each having an assigned threshold level (i.e., the number of such components that are required to obtain the secret). Any component having a lower threshold level can satisfy the role of a component having a higher threshold level. The multiple threshold scheme provides a hierarchical scheme that allows the secret, R, to be shared among different groups of people with different thresholds.

Title: A method for optimal microphone array design under uniform acoustic coupling constraints
Inventor: TETELBAUM MICHAEL
IPC: H04R1/40
Filed: 2004-09-15
Abstract: A method of designing a beamformer, and a beamformer made in accordance with this method, characterized by a uniform speakerphone response condition, resultin g in optimal beamforming directivity under a uniform coupling constraint. According to th e present invention, a finite number of individual beamformers are constrained to have the same response to a loudspeaker signal (as well as the same gain in their respective look directions) without specifying the exact value of their response to this signal. This results in beamformer weights that are optimal in the minimum variance sense and satisfy the uniform coupling constraint. The minimum variance condition combines all beamformer weights at once, and the uniform coupling constraint is expressed as a finite number of linear constraints on the weights of the individual beamformers, without specifying an arbitrary, a priori value for the actual value of the uniform response.
