Abstract: A dishwasher includes an independent presoak system which may be activated by a user of the dishwasher. The dishwasher presoak system utilizes a storage tank, supply tubes, and set of nozzles which are independent from components used in a washing cycle such that a presoak detergent is applied to items placed within a washing compartment of the dishwasher without being diluted by a standard wash cycle. As part of the presoak system, the dishwasher features a detection system which allows the user to select an automatic presoak operating state whereby the dishwasher utilizes a sensor to determine if items placed into the washing compartment are sufficiently dirty to need a presoak cycle prior to a washing cycle. The dishwasher further relies on a control system to analyze samples taken of the dirtiness levels of items placed within the washing compartment and determine whether a presoak option is necessary or suggested.

Abstract: A domestic dishwasher includes a wire rack that does not include any rolling elements that would otherwise allow the rack to roll between an extended position and a retracted position. Instead of rolling elements, the rack includes sliding surfaces that slide along corresponding surfaces inside the dishwasher and/or on a dishwasher door. The rack may be a lowermost rack.

Abstract: A household appliance including a lower rack system, the lower rack system including a lower rack movable into and out of the household appliance along first and second tracks extending from a tub of the household appliance to an interior portion of a door of the household appliance. In an exemplary embodiment, the lower rack includes a rack stop structured to limit ingress and egress of the lower rack from the tub along the first and second tracks.

Abstract: A system whereby a receiving module, in a mixed network of hardware and software-emulated modules, requires an Interrupt before it can use a Get Message OP to access a message from a message queue and which also provides a Fast Empty of messages in a message queue by eliminating the need for an Interrupt before each succeeding message access.

Abstract: A method for message transfers between digital modules in a network where some modules are hardware implemented and some modules are emulated in software. An Auxiliary Message Arbitrator Unit utilizes Main Memory storage for messages destined for receiving modules. Algorithmic sequencing means maintains chronological transfer operations of messages and uses hard and soft Interrupt signal queues to inform respective hard and soft modules of pending messages for them to retrieve.

Abstract: A method and system of message transfers in a multiple sender-multiple receiver network provides a specialized sequence for a Sender to acquire a message slot and place a message in a message queue, and a retrieval sequence for the Receiving module that insures message transmission integrity and proper chronological sequence of message delivery.

Abstract: A hardware message transfer control unit designated as the Auxiliary Message Arbitrator Unit (AMA) manages message transfers and transfer protocols in a network of sending and receiving digital hardware modules. Flexibility of network expansion to include software emulated digital modules to the hardware modules is provided in RAM circuitry at the message transfer control unit.
