Patent CA-2307443-A1 (CA)
Inventor: SVENSSON-HILFORD LENNART
IPC: B66B7/00
Filed: 2000-05-03
Abstract: Elevator installations are equipped with devices (12) for releasing aromatic substances in elevator cars and on the landings. Each of the aroma generating devices (12) has controllable valves to control the release of a number of different aromas and fragrances through outlet jets (13) which can be positioned at a limited distance from the device. The aromatic substances are released in doses of such small quantity that they are only perceptible within a maximum radius of approximately 0.5 m about the outlet jet and that this perceptibility lasts for only some seconds.      This makes it possible in an elevator car (5) or on a landing to release simultaneously from a number of jets (13) different fragrances and aromas without their combining with or negatively affecting each other.

Patent CA-2320974-A1 (CA)
Inventor: BINFORD THOMAS
IPC: G08B21/00
Filed: 1999-01-15
Abstract: In a process of detecting a person falling asleep, an image of the face of the person is acquired. Pixels of the image having characteristics corresponding to an eye of the person are selected and a histogram is formed of the selected pixels. The histogram is analyzed over time to identify each opening and closing of the eye, and characteristics indicative of the person falling asleep are determined. A sub-area of the image including the eye may be determined by identifying the head or a facial characteristic of the person, and then identifying the sub-area using an anthropomorphic model. To determine openings and closings of the eyes, histograms of shadowed pixels of the eye are analyzed to determine the width and height of the shadowing, or histograms of movement corresponding to blinking are analyzed. An apparatus for detecting a person falling asleep includes a sensor for acquiring an image of the face of the person, a controller, and a histogram formation unit for forming a histogram on pixels having selected characteristics. Also disclosed is a rear-view mirror assembly incorporating the apparatus.

Filed: 2000-10-23
Abstract: There is disclosed a fill-level detector, operating by the radar principle, for gaging the fill level of the lower of two substances filled into and layered one atop the other in a container. The detector incorporates a first electrical conductor and a second electrical conductor which conductors extend parallel to each other in an essentially straight direction and protrude into the lower substance with a generator mounted at the end of the first electrical conductor and, respectively, at the end of the second electrical conductor situated outside the lower substance and outside the upper substance for generating and transmitting an electromagnetic signal, and with a transducer mounted at the end of the first electrical conductor and, respectively, of the second electrical conductor outside the first substance and the second substance for capturing a reflected portion of the electromagnetic signal. The electromagnetic signal can be coupled into the lower substance at the end of the first electrical conductor situated in the lower substance and a portion of the electromagnetic signal reflected at the interface between the lower substance and the upper substance can be captured by the transducer. In this fashion, it is possible in the case of two substances layered one atop the other in the container to also determine the fill level of the lower substance even when the upper substance displays a very high dielectric constant.

Title: System for automatically predicting call center agent work time in a multi-skilled agent environment
Inventor: FISHER THOMAS S
IPC: H04M3/51
Filed: 2000-11-23
Abstract: The system for automatically routing calls to call center agents in an agent surplus condition provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center. Since the traffic load presented to the call center tends to be highly variable and of content that is difficult to predict, the present system provides several automatic agent assignment paradigms that each have a statistically different impact on the performance of the call center, based upon the quality and quantity of the incoming calls.

Patent CA-2330909-A1 (CA)
Inventor: MILETI ROBERT J
IPC: B29C65/22
Filed: 2001-01-11
Abstract: A heat sealing/severing device for heat sealing thermoplastic films together.  The device includes front and rear opposing jaws that are moveable between an open position and a closed position. The open position defines a zone for inserting the thermoplastic films between the front and rear jaws. In the closed position, the front and rear jaws are proximate each other to compress the thermoplastic films together. The rear jaw includes a resilient portion facing the front jaw. The heating element of the device may have a cross-sectional thickness no less than 0.55 times the cross-sectional thickness of the resilient portion. A front jaw release sheet (e.g., an unreinforced fluoroplastic) may be positioned between the insertion zone and the heating element. The front jaw release sheet may engage the heating element when the front and rear jaws are in the closed position and disengage from the heating element when the front and rear jaws are in the open position. The present heat sealer can form consistent heat seals with fewer leaks and is especially useful in sealing and severing relatively thin thermoplastic films.

Title: System and method for mobile terminal registration in an integrated wireless packet-switched network
Inventor: HERNANDEZ LAURA
IPC: H04M7/00
Filed: 1999-11-23
Abstract: A system and method of providing a dual registration scheme for a mobile terminal (112) in an integrated wireless telecommunications network (102) having a cellular network portion and a packet-switched network (PSN) portion (108). Upon detecting that the mobile terminal is moved into or powered up in the service area associated with a serving system, the serving system proceeds with the registration of the mobile terminal in the cellular infrastructure.  Thereafter, suitable messaging is provided by the serving system via a gateway (116) disposed between the cellular and packet-switched network portions to a mobility server (306) disposed in the PSN for facilating mobile terminal's registration therein. The mobility server maintains a directory for updating the location information of the mobile terminal pursuant to its registration or unregistration in the PSN. Accordingly, when a mobile terminal receives a call while roaming in a visited service area or located in a home service area, the call is routed using the registration information in the mobility server whereby the need for establishing an inter-MSC trunk is obviated.
