Title: Method and device for detailed dithering of texture level
Inventor: PIAZZA THOMAS A
IPC: G06T15/04
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an efficient calculating method by a computer which minimizes the visual effect of texture LOD transition through a polygon. SOLUTION: The visual effect can be suppressed to a minimum by obtaining dithered pixel LOD(detailed level) values by adding a dithering offset value to LOD values calculated as to respective pixels 15 covered with a graphic element. The dithering offset can be generated by looking up a table based upon the locations of pixels 15 in a pixel span. The dithered pixel LOD values are used as indexes for selecting a single LOD texture map for taking textured pixel values. Values obtained by table look-up operation are modulated to adjust the range of the dithering offset value.

Small high frequency modulation current is added to injection current of the solid-state laser so that the solid-state laser can be modulated within one bit period. The injection current is can be modulated, e.g. in 100 MHz frequency due to the modulation current. As the result of the modulation of the injection current of the solid-state laser, frequency modulation in which spectral width is represented by a modulation index m or a laser output spectrum that is subjected to phase modulation is obtained. The index m almost corresponds to the number of lines.

Title: Hygrometer
Inventor: OHASHI KAZUHIKO
IPC: G01N27/04
Filed: 1989-05-24
Abstract: PURPOSE:To simplify circuit constitution by using one operational amplifier as a constant voltage source, a current detector and a gain controller. CONSTITUTION:The non-reversal input of an operational amplifier 12 is earthed and the output thereof is fed back to the reversal input thereof through a variable resistor 13. A humidity sensor 9 is connected between the reversal input and -Vcc. Since the reversal input is always held to the same potential as the ground by feedback, stable voltage can be supplied to both terminals of the humidity sensor 9. Since the current flowing to the humidity sensor 9 flows to the variable resistor 13 to become output voltage, the gain of a circuit can be controlled by the variable resistor 13. Therefore, it is unnecessary to consider the effect of the offset voltage of the operational amplifier.
