Inventor: TOMLINSON CHARLES E
IPC: C23C22/34
Filed: 1999-03-11
Abstract: L'invention concerne des compositions et des procédés qui assurent une meilleure protection de l'environnement, une plus grande résistance à la corrosion et une meilleure adhérence de la peinture et qui sont destinés à des métaux tels que des alliages à base de fer, d'aluminium ou de magnésium ainsi qu'à d'autres surfaces de contact. Ces compositions et procédés consistent à utiliser un ou plusieurs métaux faisant partie du groupe IV-A tels que le zirconium, combinés à un ou à plusieurs métaux faisant partie du groupe III-A tels que le cérium, dans une solution acide avec un ou plusieurs anions oxy ou avec d'autres anions non fluo, et ce pour stabiliser et solubiliser les métaux pendant que les fluorures sont expressément exclus des procédés et des compositions à partir d'un certain niveau. Les procédés peuvent inclure des étapes de prétraitement pendant lesquelles on active une surface de substrat et/ou on favorise la formation de matrices d'oxydes de métaux mixtes, et ce grâce à l'utilisation d'un donneur d'oxygène. Les compositions ont un pH inférieur à environ 7,0, compris de préférence dans une plage entre 1,0 et 4,0. Les revêtements peuvent comprendre des surfactants, des chélateurs ou des additifs organiques destinés à une meilleure protection contre la corrosion et à une plus grande adhérence de la peinture. Le substrat peut être traité par immersion, par pulvérisation, par brumisage ou au moyen d'un rouleau.

Title: System for automatically routing calls to call center agents in an agent surplus condition based on service levels
Inventor: JENSEN ROY A
IPC: H04M3/523
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.

IPC: H01G5/019
Filed: 2001-01-02
Abstract: A capacitor has a polymer housing and a wound metallized film capacitive element received in the housing, with leads connected to terminals on the cover of the housing through a pressure responsive interrupter assembly. An air chamber is provided in the housing, confining a compressible volume of air, and insulating fluid fills the remaining volume of the housing, substantially immersing the capacitive element. The air chamber is advantageously defined by a piston slidably mounted in the housing. Upon a high pressure condition caused by failure of the capacitive element, the volume of air is compressed to cushion the onset of the high pressure, protecting the case from rupture prior to operation of the pressure responsive interrupter assembly.

Abstract: A method and apparatus for maintaining a determinate operational state for a controller (12) is provided that involves supplying an input voltage to the controller (12) via a main power supply (16) and periodically supplying a voltage step pulse to the controller (12) in addition to the input voltage being supplied to the controller (12) by the main power supply (16) so that the voltage step pulse does not affect the controller's operational state when that state is determinate and so that the voltage step pulse will cause the controller (12) to enter a reset mode when the state is indeterminate because of a low input voltage level being supplied via the main power supply (16).  The voltage step pulse is continuously and periodically supplied to the controller (12) via a low voltage reset circuit (10) regardless of the voltage level being supplied to the controller (12) via the main power supply (16).

Inventor: KEKKI SAMI
IPC: H04Q3/00
Filed: 1999-09-20
Abstract: A wireless telecommunications system comprises a radio network layer which provides the means to carry mobile-specific signalling, and a transport layer which establishes user channels between system nodes over a transport network. The transport network is visible to the radio network layer only via a primitive interface through which it can request transport services. The invisibility of the transport network to the radio network layer makes the radio network layer independent of the underlying transport network and enables the use of different transport network technologies. The radio network layer signalling procedures and connections are mapped with the underlaying transport layer signalling procedures and connections by using binding information. The binding information is provided in a system node (A) at one end of the connection leg, exchanged between the network and transport layers in addition to other necessary parameters through a primitive interface, and used to "identify" the radio network layer and the transport layer connection setup signalling carried out between the nodes.

Abstract: This invention is a method and system for a hybrid electric vehicle adaptive fuel strategy to quickly mature an adaptive fuel table. The strategy adaptively alters the amount of fuel delivered to an internal combustion engine to optimize engine efficiency and emissions using engine sensors.  Before the adaptive fuel strategy is permitted, an engine "on" idle arbitration logic requires the HEV to be in idle conditions, with normal battery state of charge, normal vacuum in the climate control and brake system reservoir; and, the vapor canister not needing purging, The strategy orders the engine throttle to sweep different airflow regions of the engine to adapt cells within the adaptive fuel table. In the preferred configuration, a generator attached to the vehicle drive train, adds and subtracts torque to maintain constant engine speed during the throttle sweeps.
