Abstract: A method for changing a binding relationship with a system resource involves creating a binding relationship between a process and a system resource, establishing a contract between the process and the system resource wherein a negotiation event is defined, obtaining the negotiation event in the process, and negotiating an exit from the binding relationship within a predetermined negotiation period when the negotiation event is obtained.

Abstract: A method for handling events in aggregate descendants including creating a process contract by a first process, executing a first operation in the first process, wherein a second process created by the first operation is added to the process contract, receiving a first event affecting the second process in the process contract, handling the first event in the first process, and killing the second process, if the first event is a fatal event.

Abstract: The invention is a dehumidifier comprising an adjustable float with a variable height cam surface that is in contact with the actuator of an interlock switch, which controls the supply of power to the refrigeration system of the dehumidifier. The float is rotatably mounted to the collection bucket of the dehumidifier and rotates as the bucket fills with liquid. At a sufficient amount of rotation, the cam surface will no longer be in contact with the actuator of the interlock switch, resulting in the removal of power from the refrigeration system. The float can be laterally adjusted so that a variable height cam surface is aligned with the actuator of the interlock switch to permit the user to vary the liquid level at which the interlock switch is activated to cut off power to the refrigeration system.
