Title: Method and apparatus for processing digitally signed messages to determine address mismatches
Inventor: KIRKUP MICHAEL G
IPC: H04L12/54
Filed: 2006-06-05
Abstract: A method and apparatus for processing digitally signed messages in which address mismatch errors are detected. In at least one aspect, the number of address mismatch errors reported to a user for a message may be minimized for messages that properly incorporate message portions signed by someone other than the sender of the message, as may be the case where the message contains a conversation thread for example, by performing at least one pre-determined action for digital signatures corresponding to signed data appearing after a message separator. The message separator may indicate that the message contains data from an older forwarded message or from an older message that has been replied to, for example. The at least one-predetermined action may comprise bypassing verification of address matches for those digital signatures, or verifying address matches for those digital signatures but suppressing user notification of any address mismatch errors, for example.

Patent CA-2555005-A1 (CA)
Title: Digital x-ray camera
Inventor: TURNER D CLARK
IPC: A61B6/14
Filed: 2005-03-21
Abstract: Portable x-ray devices and methods for using such devices are described. The devices have an x-ray tube powered by an integrated power system. The x-ray tube is shielded with a low-density insulating material containing a high-Z substance. The devices can also have an integrated display component. With these components, the size and weight of the x-ray devices can be reduced and the portability of the devices enhanced. The x-ray devices also have an x-ray detecting means that is not structurally attached to the device and therefore is free standing. Consequently, the x-ray devices can also be used as a digital x-ray camera. The portable x-ray devices are especially useful for applications where portability is an important feature such as in field work, remote operations, and mobile operations such as nursing homes, home healthcare, or teaching classrooms. This portability feature can be particularly useful in multi-suite medical and dental offices where a single x-ray device can be used as a digital x-ray camera in multiple offices instead of requiring a separate device in every office.

Patent CA-2572799-A1 (CA)
Title: A syringe assembly
Inventor: MAGGENI YOHANAN
IPC: A61M5/24
Filed: 2005-06-30
Abstract: A syringe assembly consists of two basic types of assembly units: a dispensing unit, and a separate, independent plunger unit. The dispensing unit and the plunger unit are assembled together coaxially to form a two-unit syringe assembly for storage or prior to use. At least the dispensing unit is a container for a material to be dispensed and, by inserting one or more extension units between the dispensing unit and the plunger unit, additional compartments may be added. Each extension unit may contain a different component of a formulation in any predetermined quantity. The syringe assembly allows the user to store one or more components of a formulation in separate individual units that can be assembled easily into a single multi-compartment syringe assembly, which can store the multiple components separately until they are ready for use, at which time the components may be mixed to form the formulation.
