Patent MX-PA05003875-A (MX)
Title: Security door and frame construction.
Inventor: BRETT DUNSTAN
IPC: E05D7/14
Filed: 2003-10-08
Abstract: This security door construction is applicable to safes, factory doors and house doors. An offset hinge assembly allows the door to swing open and closed and also to slide in and out of a door slot in the door frame at the closing edge of the door. In the construction of a safe, hooks on the inside of the door enter slots in upstands inside the safe and engage and disengage through the sliding motion. House doors and screen doors use a hinge assembly which operates in the same way as the safe. One pair of hinges are fixed to the frame and the second pair of hinges are fixed to the door. The frame and door pairs are connected by a rod or tube which ensures that the hinge axis of the door pair remains parallel to the hinge axis of the frame pair. A door locking mechanism is actuated by a conventional pneumatic door closer. A gas strut supplies the thrust to cause the mechanism to slide the door into the door slot when the door closer brings the door into register with the door slot.

Patent MX-PA05006377-A (MX)
Title: Remote control system and authentication method.
Inventor: ROBIN J BLACKWELL
IPC: G08C17/02
Filed: 2003-12-09
Abstract: A radio frequency controlled system (10,20,30) is described in which a user's remote control (30) having a unique identifier is only accepted by a device (10, 40a) to enable remote control if authenticated. The authentication process causes the device (10, 40a) to generate and issue a key sequence which the user must input. Commands from a remote control unit (30) having the identifier are only accepted if the key sequence has been previously, and correctly input. The key sequence is issued so that only a user in close proximity of the device with direct line of sight/hearing can input it on the device. Hence, inadvertent control by a neighbours' radio frequency remote control unit is eliminated. The invention is described employing the ZigBee radio standard.

Title: Method for detecting failed combustion in an internal combustion engine by a combination of combustion irregularity indices.
Inventor: ROSSIGNOL ALAIN
IPC: G01M15/11
Filed: 2004-02-11
Abstract: A method for detecting failed combustion in a mixture of fuel and a combustive in any of the cylinders of an internal combustion engine. The inventive method is characterized in that it comprises the following steps: a) a current value of an index I (t), representing operational irregularity of said engine in time, is calculated at a moment (t) of said engine operation in at least some of the combustion phases in at least one cylinder; b) the current value at the same moment (t) of an observation function E (t) is calculated while the engine is in operation and on the basis of said current value at moment (t) of index I (t), such that E (t) = l (t) I (t+?t) wherein I (t+ ?t) is an estimated value of index I (t) at a moment (t+?t) which is different from (t); c) the current value of E (t) is compared to a given threshold, as a function of the load (C) and engine rpm, and d) combustion failure is diagnosed if the value of E (t) exceeds the threshold (S). The index I (t) is calculated on the basis of a linear combination of at least two elementary indices (I1, I2,I3) , each representing operational irregularities of the engine in a given operating domain (?C,?N) of the engine, the elementary indices (I1, I2,I3), being weighted in the combination by given coefficients of relevance (alphabetagamma) obtained in operating conditions which are substantially identical on an reference engine on a test bench.

Patent MX-PA05010421-A (MX)
Title: Optical disc and method of protecting same.
Inventor: KUCHMAN TODD J
IPC: G11B7/24
Filed: 2004-02-10
Abstract: An optical disc for storage and retrieval of digital data, and a system and method for protecting the optical disc is disclosed. The optical disc has projections or embossments on one or both major surfaces. When the optical disc is placed on a substantially flat surface such as a tabletop or a desktop, the projections act as pedestals that elevate the optical disc above the flat surface. The resulting gap or clearance helps prevent damage to the optical disc caused by contaminants on the flat surface or by defects in the flat surface. The projections are sized to provide adequate clearance between the disc and the flat surface, while minimizing interference between the projections and components of optical disc readers and drives. One or more projections or projection types may also be configured with a flat surface at a point of contact to an external surface to enhance weight distribution, for example. The projections or projection types that may be configured to enhance aerodynamics. The optical disc may also include one or more depressions that are sized and configured to receive projections from another disc, which facilitates stacking of the optical discs.

Title: Mechanism for controlling motion by friction.
Inventor: ARRIAGA MARISELA ROJAS
IPC: F16F15/00
Filed: 2005-10-13
Abstract: The present invention is related to a mechanism for controlling motion by rectilinear-movement friction useful for reducing movements and/or vibrations on the structure to be applied, which is easily applied and actuated by a load impulse. The inventive mechanism consists in a spring inserted into a tube in order to avoid deformations while the spring is elongated or compressed, said spring including a support located at the end portions thereof, which has at least a hollow located in at least one of the surfaces thereof useful for supporting and housing a friction bearing. The bearing has protruding outer surfaces having diverse coupling shapes such as edges and channels, amongst others, which are coupled to the predetermined motion travel of the structure where the mechanism is applied, thereby allowing said spring to be arranged at pressure between the predetermined motion travels, and the structure where the mechanism is applied to overcome the spring resistance after a load is lo cated over the mobile base of said structure, the bearing surface and the predetermined motion travel surface being therefore frictioned against each other upon continuous and constant contact caused by the sliding action, thereby reducing movements and/or vibration characteristic of said action(see figure 1).

Title: Alfavbeta3 and alfavbeta6 integrin antagonists as antifibrotic agents.
Inventor: POPOV YURY
IPC: C07D213/74
Filed: 2004-09-16
Abstract: This invention relates to inhibition of alphav integrins, especially alphavß3 and alphavß6 integrins, by specific antagonists, preferably non-peptidic antagonists, related compounds and compounds with comparable specificity, that downregulate fibrogenesis by inhibiting cell migration and production of pro-fibrogenic molecules (e.g., collagens, TIMP-1) and cytokines (e.g., CTGF) by activated hepatic stellate cells/myofibroblasts, activated epithelia and endothelia. These antagonists alone or in combination with other agents can effectively prevent, mitigate or even reverse development of advanced fibrosis, such as fibrosis/cirrhosis of the liver and fibrosis of other organs, such as lungs, kidneys, intestine, pancreas, skin and arteries.
