A meal planning system that facilitates planning at least one meal includes at least one appliance configured to complete a physical cycle of operation on an article, memory in a non-transitory computer readable medium having appliance user domain data related to at least two user participants in the at least one meal, and control system domain data related to available cycles of operation for a set of appliances to complete a physical domestic operation on an article. A meal planner module configured to query the appliance user domain data and the control system domain data and select the at least one meal.

A technique is disclosed for facilitating editing of editable code in an interface device or similar apparatus. Properties of device elements are enumerated by a general purpose engine resident on the interface device. The general purpose engine enumerates the properties in response to a query in a design-time environment. The device element includes a specific property type and editable code consistent with the property type. A server module on the device serves the editable code and an editing environment from the interface device to a configuration station. The code can be edited on the configuration station in the editing environment and restored to the interface device. The technique alleviates the need for separate editing software or storage of the editable code in any location other than on the interface device itself.

A user interface system for a process plant includes a graphic display editor to configure a process graphic display having a graphic display element representative of a process plant element of the process plant. The process graphic display is specified via configuration information set forth in a declarative language. A graphics rendering engine generates a depiction of the process graphic display during runtime based on commands derived from the configuration information set forth in the declarative language. The configuration information for the process graphic display may be stored as an object, which, for instance, may include first and second portions to define a graphical parameter and identify a data source, respectively. The graphical parameter may be directed to defining a graphical depiction of the process plant element and, to this end, may be set forth in a formal in accordance with the declarative language. The data source may specify a location or path for data indicative of on-line operation of the process plant element to be displayed via the graphical depiction.

A direct digital drive audio system and method system and method are presented. The direct digital drive system and method utilizes a digital signal to directly drive the speakers. In one exemplary implementation, an audio system includes a sample register, an convergence adjustment component, an accumulated error register, a digital driver and a speaker. The sample register is coupled to the convergence adjustment component which is coupled to the accumulated error register and the digital driver which in turn is coupled to the speaker. The sample register holds an audio sample. The convergence adjustment component calculates the error for each sample. The accumulated error register stores an accumulated error. The digital driver determines whether to drive on a positive digital value, drive on a negative digital value or not drive. The speaker creates audio sounds based upon a signal from the digital driver.
