Patent CA-2509651-A1 (CA)
Title: Method and system for demonstrating the operability of secure wireless networks
Inventor: HALL ERIC P
IPC: H04L12/28
Filed: 2003-12-22
Abstract: Network demonstration techniques are disclosed which allow a fully-operational, secure wireless network (100) to be implemented at a customer location. Using only a portable authentication server (110), a laptop computer (105), and at least two access points (115, 120), a wireless network can be set up at the customer location within a matter of minutes, so that a user of a portable computing device (125) having an appropriate network interface card (127) is able to roam throughout the customer location with the benefit of a wireless connection to one of the access points. The laptop computer (105) contains software integrating the functionality of a security server (135), a user authentication database (130), and other components (140, 145) necessary to implement the wireless network. The user may also be able to communicate with the laptop computer (105) and authentication server (110) from locations external to the customer location, perhaps using a wireless wide area network or secondary wireless local area network. Using the network demonstration and related information about the customer, accurate cost estimates for installing a company-wide wireless network can be generated.
Patent CA-2511667-A1 (CA)
Inventor: KOSHY VETTITHARA C
IPC: C08J9/04
Filed: 2003-12-12
Abstract: L'invention concerne une mousse structurale à deux composants présentant une grande capacité d'expansion, qui peut atteindre environ le double de son volume initial en gardant une bonne structure alvéolaire. Cette mousse contient des résines époxydes. Chaque composant de ce système de mousse est stable au stockage, p. ex. n'est pas sujet à une séparation de phases, mais une fois combiné, réagit de manière à former un matériau traité présentant un module et une résistance à la compression exceptionnels. Le système de soufflage utilisé pour préparer la mousse permet de produire une mousse d'aspect uniforme, essentiellement exempte des grands vides fréquents dans les compositions thermodurcissables à deux composants classiques, même si la masse utilisée est relativement grande.

Patent CA-2540759-A1 (CA)
Title: High discharge capacity lithium battery
Inventor: MARPLE JACK W
IPC: H01M50/494
Filed: 2004-11-19
Abstract: A lithium/iron disulfide electrochemical battery cell with a high discharge capacity. The cell has a lithium negative electrode, an iron disulfide positive electrode and a nonaqueous electrolyte. The positive electrode mixture containing the iron disulfide contains highly packed solid materials, with little space around the solid particles, to provide a high concentration of iron disulfide within the mixture. The separator is thin, to allow more space within the cell for active materials, yet strong enough to prevent short circuits between the positive and negative electrodes under abusive conditions, even when swelling of the cathode during cell discharge places additional stressed on the separator. As a result, the ratio of the interfacial capacity of the positive electrode to the electrode interfacial volume is high, as is the actual capacity on low rate/ low power and high rate/high power discharge.

Inventor: KUCKUK ANDRE
IPC: F01L1/14
Filed: 2006-05-02
Abstract: The invention proposes a switchable cam follower (1) for a valve train of an internal combustion engine, said cam follower comprising two elements (2, 3) telescoped into each other and axially displaceable relative to each other. A bore (4) comprising at least one piston (5) extends in the inner element (2).  The piston (5) has, on a portion of its outer peripheral surface (7), a stepped entraining surface (8) that starts from the first front end (6) of the piston (5) facing the outer element (3). For achieving coupling, the piston (5) can be displaced with this entraining surface (8) onto a flat counter surface (10) of the other element (3). The entraining surface (8) of the piston (5) extends, starting from the first front end (6), toward a second front end (11) of the piston (5) while tapering into a conical shape generally in the direction toward a longitudinal axis of the piston (5). Besides this, an edge region (12) of the entraining surface (8) on the first front end (6) is additionally provided with a cylindrical, outwards arched (with reference to a starting point of the radius (R)) contour (13) that extends orthogonally to the longitudinal axis of the piston (5). In this way, during the coupled state of the piston (5) and its inevitable tilting, the edge abrasion feared in the prior art does not occur any longer. The manufacturing tolerances in the region of coupling can be coarsened, i.e. slackened.
