Title: Method and system for solving an optimization problem
Inventor: ERRAMILLI ASHOK
IPC: G06F15/18
Filed: 2005-10-21
Abstract: This invention provides a method and system for solving an optimization problem under a set of constraints. A set of solutions is evaluated under the set of constraints(202). Initial violation metrics and states are generated (204), based on at least one constraint corresponding to the solutions violating the constraints. A set of candidate solutions is generated from the existing set of solutions by a set of operators (206). The set of candidate solutions is incrementally evaluated (208) in a manner that is independent of the operators and the constraint. In case an evaluated solution is accepted (210), the violation metrics and states are updated (212) on the basis of the accepted solution. However, if the evaluated solution is not accepted (214), a next candidate solution is increméntally evaluated. This process is repeated till all the candidate solutions are not checked for acceptance. Finally, the method terminates if a stopping criterion is met . (216)

Title: Mould for the aluminothermic welding of rail tracks, at least one of which is worn out
Inventor: DELCROIX FREDERIC
IPC: B23K23/00
Filed: 2007-05-24
Abstract: The mold for aluminothermic welding of rails of longitudinally aligned railroad, comprises pieces of rigid refractory material such as an agglomerated sand susceptible to be temporarily assembled around two transversal ends of rail, a mold imprint opened towards the top, two continuous casting staves arranged for leaning against a second zone adjacent to the first zone of each rail, and a compressible coating in liquid form for sealing the support against the welding metal. The mold imprint is arranged to receive a welding metal at liquid state by casting and enclosing both ends. The mold for aluminothermic welding of rails of longitudinally aligned railroad, comprises pieces of rigid refractory material such as an agglomerated sand susceptible to be temporarily assembled around two transversal ends of rail, a mold imprint opened towards the top, two continuous casting staves arranged for leaning against a second zone adjacent to the first zone of each rail, and a compressible coating in liquid form for sealing the support against the welding metal. The mold imprint is arranged to receive a welding metal at liquid state by casting and enclosing both ends, a gap spared between them and a first zone of each rail. The compressible coating is limited at the parts of each casting stave corresponding to a bottom, a side and a top of a flange of the rail. The flange corresponds to the sides of a web of the corresponding rail. The rigid refractory material is directly exposed in the parts of the stave. A spacing is less than the spacing between the top and bottom of the head of the rail. The rigid refractory material is treated to facilitate its selective removal in the parts of each casting stave thus allowing an adaptation of the mold to rails. A localized lamination of each casting stave is used in its part corresponding to the bottom of the corresponding rail head. Markers are used for selective removal of the refractory material, and constituted by gradings in the localized lamination. The two casting staves are reciprocally symmetrical in relation to a plane coinciding roughly with a transversal plane of symmetry between the two rail ends. A third part is arranged below each rail, and constitutes parts of the staves corresponding to a bottom of the flange. The coating comprises a refractory fiber felt bound by a refractory binding that is adhered to the parts by a refractory glue.

Title: Perforated multi-layer optical film luminaire
Inventor: WHITEHEAD LORNE A
IPC: F21V5/00
Filed: 2006-01-11
Abstract: The light emitting surface (32) of an image display light box (30) is formed of multi-layer optical film having a reflectance greater than 95% and preferably about 99% or greater. This more efficiently utilizes light rays emitted by the light box's internal light source (36), since the multi-layer optical film reflects the light rays many times before the rays are absorbed and lost. Consequently, the light emitting surface (32) can have a light transmissivity characteristic which is macroscopically invariant as a function of position on the light emitting surface (32). Light boxes (10) utilizing prior art reflective materials require cumbersome, time-consuming, iterative trial and error techniques which must be customized for each light box (10) in order to compensate for light absorption losses by imparting a variable transmissivity characteristic to the reflective material.

Patent CA-2616220-A1 (CA)
Title: Method and apparatus for implementing soft switching in a class d amplifier
Inventor: MENDENHALL ERIC
IPC: H03F3/217
Filed: 2006-07-28
Abstract: The present invention provides lossless switching by configuring the output inductor so that the ripple current amplitude at load conditions results in small negative current during switching. The reconfigured output inductor results in increased ripple current amplitude. This increased ripple amplitude may be further controlled using zero ripple steering techniques to eliminate ripple at the output capacitor. A ripple steering technique involves adding a secondary output to the class D amplifier which steers the switching ripple away from the main output thus substantially relieving the main output from a major artifact of prior art Class D amplifiers.

Title: Methods for redefining patient, staff and visitor profiles used in monitoring quality and performance at a healthcare facility
Inventor: ROGERS MARK E
IPC: G16H10/60
Filed: 2006-12-08
Abstract: Methods, systems and computer program products are used in monitoring patients, staff, assets and visitors at a facility, initiating a response to prevent or mitigate harm, and assess and ensure overall quality and performance, and refine individual patient, staff and visitor profiles. A plurality of sensors throughout the facility provide multiple data streams relating to the locations of patients relative to at least one of caregivers, assets, other patients, visitors or one or more fixed locations. A computer system analyses the data stream and determines the location and/or movements of the patients relative to the caregivers, assets, other patients, visitors and/or fixed locations. A profile containing individual data for the patient is used to accurately detect events, including actionable events, ensure completion of prescribed care, assess patient wellness, and, in some cases, provides tailored patient specific responses to detected events. Patient profiles are periodically refined by means of an information feedback loop in order to more accurately predict (actionable) events, provide adequate care and ensure a desired level of patient wellness. Staff and visitor profiles can be used to measure staff and visitor performance at a facility.
