Patent CA-2299837-A1 (CA)
Title: Electrical component for surface-mounting on a circuit board
Inventor: ISAC VICTOR
IPC: H01R12/57
Filed: 2000-03-02
Abstract: A novel surface-mount electrical component for mounting on a circuit board. The electrical component includes at least one pin and a retaining surface. The pin serves as both a point of electrical contact between the electrical component and the circuit board and as a solder-anchoring point. The retaining surface is remote from the pin and serves as an additional solder-anchoring point for restricting the movement of the electrical component on the circuit board. Both the pin and the retaining surface are coplanar, ensuring even soldering of the electrical component to the circuit board.

Title: Watermarking of digital image data
Inventor: MENG JIANHAO
IPC: H04N7/46
Filed: 1998-10-27
Abstract: Digital watermarks can serve to indicate copyright ownership of digitized video. When video images are transmitted as transformed by discrete cosine transformation (DCT) for compression, with or without motion compensation, it is advantageous to include a watermark after transformation. To this end, a DCT watermark is generated for optimal visibility based on the original image data, and the generated watermark is superposed on the transformed data.

Title: An acoustic ink jet printhead design and method of operation utilizing ink cross-flow
Inventor: HADIMIOGLU BABUR B
IPC: B41J2/045
Filed: 2000-07-11
Abstract: A droplet emitter with an array of droplet emitting devices constructed such that a flowing liquid used create the droplets can flow through the droplet emitter at higher flow rates. The higher flow rates prevent excess heat absorption during the droplet emission process and allow for excess heat generated by control electronics to be transferred to the flowing liquid after droplet emission but before it leaves the droplet emitter. This prevents excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.
Patent CA-2315119-A1 (CA)
Title: Centralized queuing for atm node
Inventor: OSTMAN MATTIAS
IPC: H04L12/56
Filed: 1998-12-08
Abstract: An ATM switching node has a queuing resource (230) connected to an ATM switch core (30). The queuing resource provides centralized queuing for ATM cells destined for routing through the ATM switch core to plural output links. The ATM switch core routes an ATM cell destined for any output link requiring queuing to the centralilzed queuing resource. ATM cells for output links not requiring queuing are not directed to the queuing resource. The queuing resource has a link multiplexer (280) for each output link which is handled by the queuing resource. Each link multiplexer has both a first stage (304) and a second stage (302). The second stage comprises plural queues (312) for storing ATM packets and a second stage multiplexer (314) for selecting the ATM packets stored in the plural queues of the second stage for transmission to the first stage. The first stage comprises plural queues (320) for storing ATM cells and a first stage multiplexer (330) for selection of ATM cells including ATM cells formed of multiplexed ATM packets of the second stage for discharge from the queuing resource. The centralized and selective queuing resource obviates the necessity for queuing at each terminal board connected to the ATM switch core.

Abstract: A vapor emanation system includes a plastic housing having a socket portion and an electric plug portion. A decorative miniaturize container containing liquid to be evaporated by heat, has a body for storing the liquid and a neck connected to the body for engaging the socket portion of the housing for supporting the container on the housing. The neck has a passage there through and a retaining ring is fixed in the passage. A hole extends through the ring. A wick having an upper portion extending through the hole of the retaining ring also has a lower portion extending down into the body of the container for absorbing liquid from the container and for moving the liquid into the upper portion of the wick by capillary action. A tangential electric heater in the housing heats the upper portion of the wick above the neck to evaporate liquid from the wick. A retaining pin extending through the wick below the neck, extends radially beyond the wick by an amount which precludes upward extraction of the wick from the retaining ring to prevent a child from removing the wick and being exposed to the liquid.

Pendant l'opération d'étalonnage, une fonction de mesure est dérivée afin de corréler les lectures des mesures de la jauge extensométrique avec le volume du liquide dans le récipient. La fonction est enregistrée dans un processeur qui relève des données à partir de la jauge d'extensométrie, et calcule le volume réel du liquide dans le récipient. Un composant de sortie affiche la mesure. Le dispositif (10) de l'invention peut être utilisé dans de nouveaux récipients et peut être facilement monté après coup sur les récipients existants, du fait que la forme intérieure du récipient est exprimée dans la fonction de mesure.
