Title: Light source control system
Inventor: YOULE GORDON DAVID
IPC: G05F1/00
Filed: 2005-02-10
Granted: 2009-05-19
Abstract: A system and method for controlling an optical light source is provided. A current source drives the light source, while the voltage across and the current through the light source is measured. The voltage and current are converted to digital signals and sent to a neural network, which generates a modeled optical output power of the light source and a modeled value of the optical wavelength. A control circuit receives the modeled optical output power and wavelength and sends a control signal to the current source to minimize the difference between the desired power output and the modeled output power. In addition, a control signal is sent to a Pettier driver to control the temperature of a Pettier cooler in order to increase or decrease the wavelength emitted by a laser diode.

Title: Multi-antenna transmission for spatial division multiple access
Inventor: WALTON J RODNEY
IPC: H04J99/00
Filed: 2004-11-12
Granted: 2012-10-23
Abstract: An uplink channel response matrix is obtained for each terminal and decomposed to obtain a steering vector used by the terminal to transmit on the uplink. An "effective" uplink channel response vector is formed for each terminal based on its steering vector and its channel response matrix. Multiple sets of terminals are evaluated based on their effective channel response vectors to determine the best set (e.g., with highest overall throughput) for uplink transmission. Each selected terminal performs spatial processing on its data symbol stream with its steering vector and transmits its spatially processed data symbol stream to an access point. The multiple selected terminals simultaneously transmit their data symbol streams via their respective MIMO  channels to the access point. The access point performs receiver spatial processing on its received symbol streams in accordance with a receiver spatial processing technique to recover the data symbol streams transmitted by the selected terminals.

Abstract: The present invention relates to methods and arrangements for setting up a policy controlled bearer service for delivery of a service from an application function (304) to a mobile terminal (301). According to the present invention a terminal identity of the mobile terminal may be used to bind to applicable policy information when setting up the bearer service. Thus the present invention obviates the need to transmit specific binding information to the mobile terminal during application layer signaling for the purpose of policy controlled bearer service set-up. The terminal identity is registered (308) in a register of a policy decision function (303) along with policy identifying information. When a bearer service activation request is received from the mobile terminal (301) the request is mapped (313) to applicable policy information by means of the terminal identity and the matching registration in the register of the policy decision function (303).

Granted: 2012-12-04
Abstract: There is provided a filled paper containing a coated filler obtained by coating a filler with a acrylamide copolymer (composite PAM) comprising (A) an anionic polysaccharide and (B) a cationic and/or an amphoteric acrylamide copolymer. The composite PAM is obtained, for example, by mixing the component (A) and the component (B). Since the filler is treated with a combination of the components (A) and (B) different from each other in charge properties and structure, suitable coagulation effect can be attained and the coated filler has excellent affinity for pulp slurry. Therefore, even in the case of a highly filled paper, a large paper strengthening effect can be attained by using a small amount of the chemical agent.

Granted: 2010-12-21
Abstract: A quantitative visual test measures the rate at which an individual is able to complete a defined visual task, either on paper or on a self illuminated screen. The task involves comparing a plurality of similar appearing numbers to determine if they are an exact match within predetermined levels of time. Inability to complete the test within the predetermined level of time indicates the likelihood that the individual will exhibit visual stress and dyslexia. Individuals under such stress are then remediated by the use of adjusted lighting environments sometimes including other visual aids.
