A computer provided with an intelligent batteryfor charging/discharging, the intelligent batterysupplying power to a main system unit, wherein the intelligent batteryincludes: a voltage measuring circuitfor measuring a battery voltage of the intelligent batterya current measuring circuitfor measuring a charging/discharging current of the intelligent batterya temperature measuring circuitfor measuring a temperature of the intelligent batteryand a CPUfor periodically reading the battery voltage measured by the voltage measuring circuitthe charging/discharging current measured by the current measuring circuitand the temperature measured by the temperature measuring circuitso as to manage a capacity deterioration of the battery due to a storage deterioration and a cycle deterioration, and wherein the main system unit includes an embedded controllerfor receiving information about the capacity deterioration from the CPUof the battery.

Electric device with intelligent battery system therein

The present invention provides an electrical apparatus, program and method for a user to display a preliminary charging state in a battery. In one aspect, the present invention provides an electrical apparatus that is capable of receiving a battery for supplying electric power to a main unit by discharging after charging, comprising preliminary charge judging means for judging whether or not the battery is in a preliminary charging state that is a recovery from over-discharge, and display means for displaying an indication of preliminary charging if the preliminary charge judging means judges that the battery is in the preliminary charging state.

Preliminary charging state apparatus, program and method

A method and apparatus for independently and dynamically performing smooth-scrolling a display line at a time is disclosed herein. An offset value for smooth-scrolling for each display line, is provided which shifts the image information of each display line by pixel. Rewriting of the screen according to the offset value is performed in synchronization with refreshing of the display screen. Selective smooth-scrolling can be performed for a displayed image in each display line, and complicated and various image display can be shifted by controlling the existence or nonexistence and speed of smooth-scrolling for each display line.

Method and system for smooth scrolling of a displayed image on a display

A raster scan type display apparatus for displaying characters having attributes. The attributes are, for example: (i) underlining, (ii) reverse video, (iii) high intensity, and (iv) blinking. The characters and attributes are stored in a refresh memmory. The display may be operated in either a field attribute mode or in a character attribute mode. In the field attribute mode, one field attribute byte in the refresh memory sets the attributes for at least one, but usually many characters which follow the field attribute byte in the refresh memory. In the character attribute mode, one character attribute byte in the refresh memory sets the attribute for only one character which precedes the character attribute in the refresh memory. In the character attribute mode, field attributes may be provided (in addition to the character attributes) for strings of characters following the field attributes.

Display apparatus

This invention features the use of two paralleled insulated gate depletion channel field effect transistors (FET) having their gates connected one to the source voltage and one to the drain voltage to provide a linear resistance element. The actual resistance value can be controlled by selecting design parameters and can be extended by using a plurality of such elements in series to provide greater resistances and/or higher voltage capabilities or in parallel to provide greater current capacity. The described resistor is used as a cost and space saving alternate to discrete resistor components and is particularly useful as a part of an integrated circuit in analog type devices.
