Abstract: A fluid coupling for fuel lines in motor vehicles, includes a housing having a receptacle for a counterpart, a blocking member in the receptacle and engageable behind a blocking rib of the counterpart to fix the counterpart in the receptacle, and a detection sleeve axially movable in the receptacle, and having a first engagement portion, which engages with the blocking rib to move the detection sleeve axially into a detection position, and at least one second engagement portion arranged behind the first engagement portion and, when the counterpart is pulled out, engages with the blocking rib to move the detection sleeve out of the detection position, into the initial position, and the detection sleeve includes at least one detection portion (64), received within the receptacle in the initial position so the detection portion is not visible from the outside and, in the detection position, visibly protrudes from the receptacle.

Abstract: A data processing system comprising a plurality of processing units that are configurable as different partitions of processing units. The system comprises a multicast communication network for routing cache communications within a partition of processing unit. A cache controller of one of the processing units within a partition is configurable as a master cache controller for a set of caches within the partition. The master cache controller is operable to issue requests over the multicast communication network to all of the caches in the set of caches at the same time. The multicast communication network is configured to combine response signals from the different processing units within the partition to provide a combined response signal to the master cache controller that represents an overall request-response status for the caches to which the request was issued.

Abstract: Embodiments of a circuit, a buffered crosspoint switch that includes the circuit and a computer system that includes the switch are described. In this circuit and switch, deep crosspoint buffers are replaced with smaller distributed buffers. This modification reduces the cost of the switch and improves the scaling properties of the architecture.
