Providing an information processing terminal of a folded structure comprising a first housing portion having a form factor defined by PCMCIA and a second housing pivotally coupled to the first housing portion with an improved reliability of a cable passing through the coupling portion. The data processing part, which is a core part of the PDA function, is contained within the second housing portion which is not subject to restriction of shape and size. As a result, the first housing portion which has to conform to the PCMCIA/JEIDA specification may be relatively easily designed. For example, while the information processing apparatus is provided with a key input means in the first housing portion, it is possible to use a high function key board such as a keyboard of an excellent feel of key touch or a back lighted keyboard.
摘要:
A method executed in an information processing apparatus for controlling resource access by an application program running on the information processing apparatus is provided. A change in connection statuses or operating statuses of a device connected to the information processing apparatus is first detected. In response to the detection, a resource access condition to be applied to the information processing apparatus is selected based on certain criterion. The selected resource access condition is stored in a condition storage unit. Then, in response to capture of a function call for resource access issued to an operating system by the application program, the resource access condition is read from the condition storage unit, and it is determined on the basis of the resource access condition whether the captured function call is allowed. If it is determined that the captured function call is not allowed, the function call is rejected.

An external storage device for storing data comprises judgment means and access processing means. The judgment means determines whether or not a specified data pattern can be used as a replacement to record a data block. Namely, judgment means determines that a data block can be recorded by using a specific data pattern when the data block and the data pattern match. The access processing means stores identification information for identifying the specified data pattern used to record the data block rather than storing contents of the data.

An external storage device 110 includes a semiconductor memory 200, a hard disk 210 having an access speed lower than that of the semiconductor memory 200, a judgment part 275 for determining whether or not data can be stored in the semiconductor memory 200, and an access processing part 277 for compressing and storing data into the semiconductor memory 200 after it is determined that the data can be stored in the semiconductor memory 200, and for storing the write data into the hard disk 210 when it is determined that the data cannot be stored in the semiconductor memory 200. The storage capacity of the external storage device 110 is larger than the storage capacity of the semiconductor memory 200.

A transmitted illumination type meter comprises a transparent light transmitting board having both a light entering bore and a shaft passing bore formed therethrough; a translucent dial plate placed on a front surface of the board, the dial plate having a shaft passing opening mated with the shaft passing bore of the board; a movement positioned behind the board; a light source positioned within the light entering bore; a drive shaft extending from the movement to the outside of the dial plate through the shaft passing bore and the shaft passing opening; a transparent pointer connected to the drive shaft to move over a front surface of the dial plate; and an annular convex peripheral wall defining the light entering bore. The annular convex peripheral wall allows light beams from the light source to enter the board and travel in parallel in the same. A plurality of stepped annular light reflecting surfaces are formed on a rear surface of the board and arranged to be concentric with the light entering bore. The annular light reflecting surfaces reflect the light beams from the annular convex peripheral wall toward the front surface of the light transmitting board. A Fresnel lens is formed on the front surface of the board and arranged to be concentric with the light entering bore. The Fresnel lens projects the light beams from the annular light reflecting surfaces toward the dial plate.
摘要:
Screen interpolation is done without using an expensive line buffer, etc., to enlarge and display an original image without incongruity. Rather than computing an interpolated pixel value as an average of adjacent pixel values and displaying the computed average pixel value in each frame, in accordance with this invention a pixel to be interpolated assumes one of the adjacent pixel values in each frame, but in successive frames assumes different adjacent pixel values in a mix such that the average value of the interpolated pixel over many frames becomes the desired interpolated value. Since successive frames are displayed very rapidly, to the human eye the afterglow (or visual persistence) phenomenon causes the screen to appear as if an enlarged image is being displayed at all times without incongruity (i.e., the varying values of the interpolated pixels are not noticed by the human eye).
摘要:
This invention relates to a video graphic control method and controller for sending to a display device graphic data from a processing device, and the object thereof is to provide a video graphic controller that increases the bandwidth available to a graphic engine or CPU without increasing power consumption or manufacturing costs, even when used with a conventional frame memory. A video graphic controller for controlling video data by storing the video data from a CPU 4 in a frame memory 18 and causing the frame memory 18 to output the data to a display device 30 uses a video data comparison means 20 to compare a piece of video data stored in the N-th address of the frame memory 18 to another piece of video data stored in the N-1-th address in order to determine whether the two pieces of data match, and if the two pieces of data match, outputs to the display device 30 the piece of video data stored in the N-1-th address instead of the piece of video data stored in the N-th address.
