Abstract: A display driving method drives a display to make a gradation display on a screen of the display depending on a length of a light emission time in each of sub fields forming 1 field, where 1 field is a time in which an image is displayed, N sub fields SF1 through SFN form 1 field, and each sub field includes an address display-time in which a wall charge is formed with respect to all pixels which are to emit light within the sub field and a sustain time which is equal to the light emission time and determines a luminance level. The display driving method includes the steps of setting the sustain times of each of the sub fields approximately constant within 1 field, and displaying image data on the display using N+1 gradation levels from a luminance level 0 to a luminance level N.

Abstract: A display apparatus displaying gray scale by using a subfield method has a gain control circuit, a sub gain control circuit, and an error diffusion circuit. The gain control circuit has the number of gray scale levels of an input signal and outputting a first intermediate image signal with a first number of gray scale levels, and the sub gain control circuit receives the first intermediate image signal, compresses the number of gray scale levels of the first intermediate image signal, and outputs a second intermediate image signal with a second number of gray scale levels. The error diffusion circuit receives the second intermediate image signal and increase the number of gray scale levels by simulating additional gray scale levels through error diffusion.

Abstract: A plate spring urges a base of a buckle device toward an anchor insertion opening side with respect to an anchor plate. Provided that urging force of the plate spring exceeds urging force of a spiral spring, the base is held, by the urging force of the plate spring, at a position at which a rivet contacts an insertion direction side end portion of a long hole. However, when the urging force of the spiral spring exceeds the urging force of the plate spring due to, in order to attach a child seat, pulling out of a webbing belt more than at a time when a body is to be restrained, the base moves against the urging force of the plate spring, and the plate spring pushes a transfer rod. Due to this pushing force being detected by a semiconductor diffusion strain gauge, it can be detected that the child seat is attached on a seat.

In the buckle device, a magnetic plate is provided at a leg portion which moves together with the tongue plate which is inserted into an interior of the case. Changes in orientation of a magnetic field of a magnet of a sensing section, which orientation varies due to the magnetic plate approaching and moving away from the magnet, are detected at an MRE sensor.

Abstract: A display has a panel, and first and second electrodes. The first and second electrodes define a matrix of cells on the panel. The second electrodes, which correspond to lines of the cells, are scanned to select the cell lines one by one. The first electrodes are driven to set display data for a selected one of the cell lines. The display also has a sequence setting unit for setting sequences of scanning the second electrodes, and a sequence selection unit for selecting one of the sequences that minimizes the current and power consumption of a first-electrode driver without deteriorating the quality of the displayed images.

Abstract: A position sensor has a magnet producing a magnetic field and a magnetic detector for detecting the magnetic field. The detector produces a resistance value variable according to the orientation of the magnetic field. The magnet and the magnetic detector are arranged to move relative to each other within a predetermined stroke so that the detector outputs a voltage signal with a predetermined waveform having a rate of change that prohibits the signal excessive of a predetermined value to return to the predetermined value.

Abstract: Power consumption control is performed that does not induce unnatural changes in brightness even when data causing an abrupt change in load ratio is input, and that can make the power consumption settle down to the desired value. The load ratio is calculated from data input to a display apparatus, and the load ratio is again calculated this time backward from the present brightness value; if the difference between the two calculated values is greater than a threshold value, a new brightness value is calculated from the load ratio, and the brightness is set to the newly calculated value. Thereafter, the brightness is controlled based on measured power consumption values.

Abstract: In a plasma display apparatus with power consumption control, a control method is provided that eliminates unnaturalness of images during power control and that holds power consumption to within a target value regardless of the type of image pattern displayed. Differences between power consumption PSA and target value PSET are summed to calculate power consumption sum value PSUM, and if PSUM is negative, brightness set value MCBC is set to its maximum value MCBCMAX. If PSUM is positive, the value calculated by the equation “MCBCMAX−PSUM×MCBCMAX/PSUM,MAX” is set as the MCBC.

Abstract: An intraframe time-division multiplexing type display device prevents prominent image defects, such as flicker, and affords a high-quality image display. A single frame of an image is displayed while changing a gray-scale level thereof by means of a number of sub-frames, each sub-frame comprising at least an address period and a sustained discharge period; further, the sub-frames have respective, mutually different sustained discharge periods. A gray-scale level adjustment unit arbitrarily sets the selection sequence of each of the number of sub-frames within an individual frame that is to be in a sustained discharge state.
