Abstract: L'invention concerne un procédé et un dispositif permettant de faire bénéficier à des sociétés distinctes de la déduction pour perte autre qu'une perte en capital à la suite de l'acquisition du contrôle d'une société par une personne ou un groupe de personnes tel qu'édicté dans les lois fiscales. Ce procédé facilite la déduction d'une perte autre qu'une perte en capital en cas d'acquisition du contrôle d'une société. Ce procédé consiste à recueillir, à stocker et à systématiser des informations corporatives et fiscales auprès de sociétés constituées en personnes morales. Les informations sont recueillies à l'aide d'une interface utilisateur web ou autrement et stockées sur un disque dur ou un serveur. Ces informations ont trait à certaines caractéristiques inhérentes aux sociétés et à leurs activités. Les informations recueillies permettent de dresser, pour chaque société, une liste de critères. Ces critères traduisent les conditions imposées par le législateur et la jurisprudence. Ces conditions, lorsqu'elles sont respectées, permettent la déduction d'une perte autre qu'une perte en capital d'une société à la suite de l'acquisition du contrôle par une personne (physique ou morale) ou un groupe de personnes (physiques ou morales). Si les conditions ne sont pas respectées, la déduction n'est pas permise. Le procédé utilise l'information recueillie afin de repérer des sociétés qui, en fonction des conditions imposées par le législateur et la jurisprudence, sont mutuellement éligibles à une déduction d'une perte autre qu'une perte en capital. Par la suite, le gestionnaire du système exploite cette information afin de jumeler des sociétés qui sont susceptibles de bénéficier de la déduction fiscale.

Abstract: Systems and methods performed by a telephony device allow the telephony device to test the quality of multiple potential paths which can be used to conduct a telephony communication. By testing the conditions that presently exist, the telephony device can choose the path that is presently offering the best quality. A telephony communication may be setup over an initial path, and then subsequent testing may determine that it is best to switch to an alternate path offering better call quality. The initial path used for the telephony communication may be the one that offers the fastest initial connection. When multiple potential paths exist, the telephony communication may be conducted over a first path while keep-alive messages are communicated over a second path so that the telephony communication can be quickly switched to the second path.

Title: Dual-ring switch for rstp networks
Inventor: DITZEL GEORGE A III
IPC: H04L12/437
Filed: 2012-03-30
Abstract: A dual-ring computer network architecture for industrial automation systems includes a dual-ring switch for interconnecting two networks, such as Rapid Spanning Tree Protocol (RSTP) networks. The dual-ring switch may provide separate control planes between the two networks but a common data plane between the networks. The system topology may include amain ring and a sub-ring, which creates separate fault regions for isolation. Using this configuration, the standard RSTP practical limit of 32 devices is no longer a limit, as the use of the dual-ring switch provides a mechanism to expand the total number of devices up to 256 while maintaining the network recovery time to within a target of 50 milliseconds. This allows for the use of dual rings using the RSTP protocol on a single switch. In another embodiment, two dual-ring switches are configured in the same sub-ring for redundancy.
