Patent CA-2342502-A1 (CA)
Inventor: JOHNSON DOUGLAS RENE
IPC: F16H59/72
Filed: 2001-03-30
Abstract: A transmission with a mechanical cold start valve that dumps the pump output to the suction side of the pump to prevent oil pressure build up and thereby prevent pump toque loads from being applied to the engine during engine cranking. The oil eventually forces the valve closed after oil passes through a long orifice passage. The length of time for this to occur is dependent on the oil temperature and the length and diameter of the orifice passage. In colder temperatures, more time will be required for the valve to close, thus aiding in the cold starting of the engine.

Inventor: HILL LAWRENCE W
IPC: B65G1/04
Filed: 1999-11-18
Abstract: An inventory control (24) and communication system provides automated real-time polling of stock levels and ordering to allow stock levels to be maintained. A bin (12) is established for each stock item. Transducers (14) are associated with each storage unit to produce a signal (18) indicative of the weight of the stock items. The signals are transmitted at regular intervals to a central inventory server, which maintains information about transducer location and the corresponding stock item. Inventory logic in the central inventory server computes the quantity of each stock item from the transducer signals and the weight of the stock items. Iventory logic also includes threshold values for the minimum and maximum quantity of each stock item. When the quantity of a stock item reaches a minimum threshold, inventory logic sends and order to the supplier to restore the stock item to the maximum quantity threshold.

IPC: H04L12/70
Filed: 1999-12-31
Abstract: A device and a method are proposed in which the sender divides an amount of data to be sent into one or more data units and the receiver acknowledges the correct receipt of data units by returning acknowledgment data units to said sender.  The data units are sent by said sender in accordance with a flow control procedure that involves one or more adaptive parameters. After a given data unit is sent, the sender performs a data loss detection routine, and if a triggering event occurs, a corresponding response procedure is conducted, where this response procedure comprises at least two different modes for adapting said one or more adaptive parameters. Preferably, there is a first and a second mode, where the first mode is associated with the actual loss of a data unit, so that this first mode comprises the conventional data loss procedures, and where the second mode is associated with the recognition that an excessive delay has taken place and not a loss of a unit.

Abstract: A system for managing licenses for protected software on a communication network is disclosed. The system comprises at least one client computer and a pool of license servers coupled to the communication network. The pool of license servers is programmed for managing licenses to use the protected software. Within the pool of license servers is a current leader server, programmed for managing all license servers in the pool, and at least one follower server programmed for managing the distribution of authorizations allocated to that particular follower server. Each license server stores a status of the authorizations allocated to that particular license server, an d each follower server communicates the status of the authorizations allocated  to that particular follower server to the current leader server. The client computers request authorizations to use the protected software from a particular license server. When a particular license server does not have a sufficient amount of available allocations, the current leader server re- assigns, where possible, the allocations within the pool. The system may als o include at least one client computer that is capable of being coupled to or decoupled from the communication network. At least one of the license server s may be programmed for granting acommuter authorization in response to a request for a commuter authorization from a client computer if there is an available authorization. After a commuter authorization is received by a client computer, the client computer stores a commuter authorization lifetim e representing a time period for which the commuter authorization is valid. Th e client computer may then use the protected software while coupled to or decoupled from the communication network until the commuter authorization lifetime expires.
