Title: Payment systems
Inventor: TYMM DAVID
IPC: G06Q20/00
Filed: 2009-09-01
Abstract: A method of processing a standards compliant payment system message to generate an electronic voucher via a portable electronic device. A payment request is made at a standards compliant POS terminal (105). The terminal forms a first concatenated string including (106) a card identifier, merchant identifier and amount, which first string is sent to a transaction processor as a message, wherein the first string is then sent to an acquirer for authorisation as a second message, which string is then amended to form a second string depending on whether the transaction has been accepted or declined. The first or second string is checked (107) to determine if the checked string contains a card identifier and a user identifier such that if a match is found, a further message is generated comprising the user identifier, which further message is transmitted for further validation (108) and in the event of further validation (109), a voucher (110) is transmitted to a user. The method enables a voucher to be sent to a user at the time of making a transaction so that the delivery of the voucher is associated with the transaction.

Title: Monitoring of replicated data instances
Inventor: MCALISTER GRANT ALEXANDER MACDONALD
IPC: G06F17/00
Filed: 2010-10-26
Abstract: Replicated instances in a database environment provide for automatic failover and recovery. A monitoring component can obtain a lease enabling the component to periodically communicate with, and monitor, one or more data instances in the data environment, where the data instance can be a replicated instance including a primary and a secondary replica. For a large number of instances, the data environment can be partitioned such that each monitoring component can be assigned a partition of the workload. In the event of a failure of a monitoring component, the instances can be repartitioned and the remaining monitoring components can be assigned to the new partitions to substantially evenly distribute the workload.

Title: Stent delivery and deployment system
Inventor: KOSS ALEXANDER K
IPC: A61F2/84
Filed: 2008-05-05
Abstract: A stent delivery and deployment system for use primarily with self-expanding stents, incorporation a traction tube extending over the length of the diametrically compacted and constrained stent and everting back over itself, with the outer everted portion of the traction tube preferably extending to the proximal end of the delivery system. A constraining sleeve is provided between the inner, non-everted portion and outer, everted portion of the traction tube, the constraining sheath extending over the length of the constrained stent prior to deployment and diametrically constraining the diametrically compacted self-expanding stent. The application of tension to the proximal end of the traction tube causes the constraining sheath to move in a proximal direction, freeing the constrained stent as it moves and allowing the stent to deploy against the wall of the body conduit within which it is located during the deployment process.

Patent CA-2793548-A1 (CA)
Inventor: PALKA KRZYSZTOF
IPC: E21B43/18
Filed: 2012-10-25
Abstract: A system and method are provided for improving hydrocarbon production from gaseous wells, and in particular improving hydrocarbon production using pumping systems employing artificial lifts. The pumping system of the well is controlled so as to cyclically decrease and increase gas pressure in the casing annulus, thus cyclically decreasing PBHP in response to the decrease in the casing annulus pressure and permitting the PBHP to increase in response to the increase in casing annulus pressure. Production of fluid from the reservoir is therefore increased during the cyclical decrease in casing annulus pressure, and production of fluid from the downhole pump is increased during the cyclical increase in casing annulus pressure. In addition, gas interference due to production of foam in the casing surrounding a downhole pump can be mitigated by forcing liquid from the foam during the period of increased casing annulus pressure.

Title: Lift shaft door unlocking mechanism
Inventor: HENSELER MARKUS
IPC: B66B13/12
Filed: 2011-05-01
Abstract: The lift shaft door unlocking mechanism operates with expander skates (4) on the door drive (3) which unlock the lift shaft door when entering the region close to an access level. A particular feature is that these expander skates (4) on the lift cabin door drive are designed to be flexible with respect to the lift cabin (1) such that, in the event of any touching of the lift shaft head at the upper end of the lift shaft, they are flexible over an adjustable distance, and, after the lift cabin (1) moves away from the lift shaft head (2), they assume their original position again. For this purpose, these expander skates (4) are displaceably mounted on the expander skate construction itself along respective guides (11). Here, they are held in the uppermost displacement position by means of tension springs (9), and can be displaced downwardly against the force of these springs (9) through application of force to their upper ends from above resulting from a collision with the lift shaft head. After their upper ends have been released, they are returned to the uppermost displacement position again by means of these springs (9).

Inventor: O'CONNOR MARTIN
IPC: G06Q40/02
Filed: 2012-12-28
Abstract: Various embodiments provide systems, methods, and computer-program products for fusing at least two scores. In various embodiments, each of the scores predicts the probability of an outcome associated with a particular unit and an angle with respect to a horizon at which an object would rest at a point on a frictionless spherical surface is calculated based on the scores. The object comprises characteristics of the particular unit at said point on the spherical surface and the scores represent a downward force of gravity that would be exerted upon the object. In particular embodiments a displaced force is calculated based on the angle and the downward force of gravity interacting according to laws of physics. The displaced force is that which would need to be exerted upon the object to compel the object to move down the spherical surface and is used as a fused score.
