The present invention has an object of providing a user interface execution apparatus and a user interface designing apparatus which can estimate the maximum size of a storage area for storing data to be prefetched when a user interface is designed and can present updated data to the user even when the prefetched data is updated after the prefetch. A user interface execution apparatus in the present invention includes a processor to execute a program; and a memory to store the program which, when executed by the processor, performs processes of: transitioning a state of the user interface execution apparatus; issuing a prefetch request for data; storing the data; generating the code from an interface definition and a state transition definition; and selecting, before transitioning the state, data to be prefetched based on a difference between a data obtaining interface to be used in a state before the transitioning and a data obtaining interface to be used in a state after the transitioning.

User interface execution apparatus and user interface designing apparatus

This relates to a technology capable of efficiently deciding a screen layer to which a user input event should be delivered even when screen layers that do not receive the user input event are displayed in an overlapping manner other than a screen layer that should receive the user input event. A user interface device includes an acquisition unit, a transmission unit, a determination unit, and a decision unit. On the basis of inquiry information from the transmission unit, the determination unit concurrently determines, for a plurality of screen layers, whether input information is accepted in each of the screen layers. The decision unit decides the screen layer based on a determination result.

User interface device and method for displaying user interface

A digital-to-analog converter includes a decoder, a full differential type low-pass filter, and first to fourth switches. The decoder has first and second inputs and first and second outputs. The low-pass filter has first and second inputs and first and second outputs. The first switch has a first terminal connected to a first reference voltage source, a second terminal connected to the first input of the low-pass filter, and a third terminal as a control terminal connected to the first output of the decoder. The second switch has a first terminal connected to the first reference voltage source, a second terminal connected to the second input of the low-pass filter, and a third terminal as a control terminal connected to the second output of the decoder. The third switch has a first terminal connected to a second reference voltage source, a second terminal connected to the second input of the low-pass filter, and a third terminal as a control terminal connected to the first output of the decoder. The fourth switch has a first terminal connected to the second reference voltage source, a second terminal connected to the first input of the low-pass filter, and a third terminal connected to the second output of the decoder.

An electronic system pocketbook apparatus includes a foldable and portable main body, an expansion card holder mounted on the main body, a necessary number of expansion cards held by the expansion card holder, and a communicating unit. The main body has a functions of right and left portions coupled by a cover, is folded upon carrying of the main body so that the right portion overlaps the left portion, a folded portion being fastened by a cover clip provided to the cover, and has basic functions of controlling arithmetic operations and display data processing by using an internal controller, data inputting means, and displaying data on a display unit. The communicating unit performs data transmission/reception between the held expansion cards and the main body via the expansion card holder.
