Title: Apparatus and method for service of an automotive automatic transmission
Inventor: CAMACHO MICHAEL JOSEPH
IPC: B62D5/06
Filed: 1998-03-09
Abstract: A fail-safe transmission service machine (12) allows old ATF (32) to be pumped out of a transmission (10B) while the vehicle engine runs, and responsively pumps a matching volume of new ATF into the transmission so that dry running of the transmission can not occur. If the supply of new ATF (28) runs out or if power to the service machine (12) is interrupted, the machine reverts to closed loop fluid circulation for the transmission. A hydraulic rectifier (42) provides for universal connection of hoses (14, 16) between the transmission cooler (36) fluid circulation loop of the vehicle and the service machine (12). An alternative embodiment of the machine allows for similarly fail-safe exchange of power steering fluid (112) from a vehicle, and replacement of the old fluid with new power steering fluid.

Abstract: The invention relates to a suit for problems associated with orthostasis which is comprised of a pair of trousers made of a slightly stretchable textile material. A plurality of essentially linear or wavy strips (14, 15) are inserted along the entire length of the trousers.      Said strips are made of double-walled, liquid-tight, slightly stretchable textile material. The two layers of this material are connected to one another at connection points. This results in the production of cavities which are filled with a liquid.      Suspenders (11) hold the trousers and are simultaneously constructed as reservoirs (12) for the liquid. In order to increase the pressure on the abdominal region, a flat bladder (13) can be placed in the trousers and, like the strips (14, 15), can be supplied with fluid from the reservoirs (12). As a result, liquid columns are produced which extend over a large portion of the body height. Said columns build up a compensating pressure on the legs and the lower abdomen. The trousers are closed by two lateral zip fasteners (21). The knees and genital region are covered by elastic inserts (16, 17). The strips (14, 15) are either essentially straight or wavy on both sides.

Title: Rules-based queuing of calls to call-handling resources
Inventor: GABRIEL CAMILLE
IPC: H04M3/436
Filed: 2000-01-19
Abstract: Resolution of contention over resources -in an automatic call distribution (ACD) system is effected as follows. Call attributes are defined for arriving calls, and resource attributes are defined for available resources. Rules are defined that match calls having particular call attributes with resources that have corresponding resource attributes.      Priorities are assigned to rules, comprising an initial value and a time function that defines how the value changes over time. Each rule preferably defines a coverage path for calls, comprising one or more resource attributes required of resources that can handle the call if the primary resources identified by the rule cannot handle the call in a timely manner. Each resource has an associated call queue. When a call arrives, rules are matched to the call's attributes, and the matching rules determine the resources that are able to handle the call. A token for every matching rule for the call is placed in the queues of all of the resources that are able to handle the call. The position of the call's token in a queue is determined by the priority of the rule. The priority, and hence the call's position in the queue, changes over time according to the rule's time function. When one of the resources removes the call's token from its queue to process the call, all tokens for the call are removed from all queues. When a token with a priority higher by a threshold amount than the priority of the call being processed by the resource appears in the resource's queue, processing of the call is preempted by the token's call
