Patent CA-2640992-A1 (CA)
Inventor: MULLIN RONALD C
IPC: G06Q20/40
Filed: 1997-04-14
Abstract: A digital signature scheme for a "smart" card utilizes a set of prestored signing elements and combines pairs of the elements to produce a new session pair. The combination of the elements is performed partly on the card and partly on the associated transaction device so that the exchange of information between card and device does not disclose the identity of the signing elements. The signing elements are selected in a deterministic but unpredictable manner so that each pair of elements is used once.  Further signing pairs are generated by implementing the signing over an anomalous elliptic curve encryption scheme and applying a Frobenius Operator to the normal basis representation of one of the elements.

Abstract: An inhaler (1) is proposed for inhaling a formulation (2) from capsules (3) that each contain a dose of the formulation. The capsules are preferably each emptied in a capsule chamber (4) by being set in motion by a stream of air flowing through the capsule chamber. The stream of air can be generated by the inhalation of a user or patient and/or can be generated actively by the inhaler. For simple handling, the inhaler has a means for, in particular, automatic filling, emptying and/or cleaning of the capsule chamber, if the latter is used more than once. Alternatively, the inhaler has a large number of capsule chambers that each preferably already contain a capsule and are preferably used just once.

Abstract: A method for communicating notifications from a server to a device includes sending a primary message including data indicating notification status information (e.g. version number, update, system state change); and sending notification messages or flows apart from the primary message addressed to specific groups of devices (broadcast; composite address). Another method for obtaining notifications in a device from a server includes monitoring the primary message or flow including current notification status information, comparing the current notification information status information with a previous notification status information to determine if a change in notification status information has occurred, and obtaining addressed notification information- when a change in the notification status information has been determined. By using a primary message with abbreviated information to communicate whether changes to notification information have occurred, system resources can be conserved.

Title: Method and apparatus for measuring pressure inside a fluid system
Inventor: BERR MIGUEL LUIS
IPC: A61B5/00
Filed: 2007-10-22
Abstract: A disclosed method determines fluid pressure inside a vessel without compromising the integrity of the vessel. A sensor is positioned in operative communication with the external wall of the vessel such that expansion of the external wall of the vessel exerts a force against the sensor that is directed substantially radially outward with respect to the vessel. A substantially radially inward force is caused to be directed against the sensor in response to the substantially radially outward force exerted by the external vessel wall. The sensor can thus be used to detect the magnitude of the substantially radially outward force. A disclosed apparatus determines fluid pressure inside a vessel without compromising the integrity of the vessel. The apparatus includes a sensor and a band operatively associated with the sensor and configured to at least partially encircle the vessel so as to retain the sensor in operative communication against the external wall of the vessel.

Abstract: A touch-free dispenser includes a dispenser controller coupled to a memory unit, which includes a database of previously-stored vein patterns. A vein-pattern sensor maintained by the dispenser images the unique vein pattern of a user's hand without contact. The imaged vein pattern is subsequently compared with stored vein patterns, such that if there is a match, the dispenser proceeds to dispense material, such as soap, from a refill container. Alternatively, if there is no match between the imaged vein pattern and the stored vein patterns, the dispenser enters a learn mode to allow the imaged vein pattern to be added to the database. Data associated with the use of the dispenser is also collected during its operation, which is stored and associated with the imaged vein patterns for subsequent analysis.
