Abstract: A communication network for connecting a plurality of electronic processing units to one another, the network having at least one switch which has at least one input port and one output port for connecting it to the electronic processing units and which is arranged to transmit a data frame of a data stream between at least two of the electronic processing units, the switch having at least one electronic circuit that is arranged to control a transit time of the data frame between the two electronic processing units.

Abstract: A tree-type fastener includes one or more fin stabilizer bases disposed on a shaft of the fastener. When the fastener is subjected to a pull-out force, the fins may be prevented from stacking up, buckling or bending by the fin stabilizer base. The stabilizer base is configured to provide no interference with a work piece when inserted in a work piece aperture. The fastener of the invention provides a high removal force to insertion force ratio and a strong, single piece device. The fastener may also be adapted for modification of new and existing tree-type fasteners.

Abstract: A retainer for holding nuts, bolts and other components includes a pocket configured for retaining a portion of the component and having an entrance opening for insertion of the component into the pocket. A deflectable blocking element is disposed in the opening and yields to insertion pressure, allowing the component to enter the pocket. A tether secured near the distal end of the blocking element resists deflection of the blocking element in response to withdrawal force applied to a component in the pocket.

Abstract: A holding clip for tubes, hoses and the like has a pocket and deflectable arms protecting an entrance to the pocket. The arms extend one past another and interdigitate one with another. The arms deflect outwardly in response to force exerted thereagainst from outside of the pocket and interengage one against another to resist force exerted thereagainst from within the pocket.

Abstract: A clip device is disclosed for removably securing a tube, such as an air conditioning condenser tube, to a bracket, such as a radiator bracket, which includes a slot. The clip includes an annular body having a first and a second edge, the body defining an opening for the removable reception therein of the condenser tube. The body includes a flexible arm having a proximal end and a distal end. The distal end of the arm defines a tooth which lockingly cooperates with the slot. The arrangement is such that the condenser tube passes through the opening of the body and then the body is further moved axially along the condenser tube so that the bracket extends through the opening and next, the body is rotated about the condenser tube such that the tooth engages the slot for removably securing the condenser tube to the bracket.
