Abstract: Tone reproduction of an image is improved by the use of error diffusion or dithering in the mapping of input pixel values on an input values scale to printer pixel values on a printer values scale, where the input values scale and the printer values scale both have more than two levels, to generate an image where a spatial average of printer values approximates a spatial average of the corresponding input values, as measured on the printer values scale. To improve the tone reproduction of reduced-resolution images, the printer pixel values are grouped into multi-pixel cells, printer pixel values within each cell are mapped to a font index value, and a font cell corresponding to the index level is printed at the location of the cell. The font set is chosen such that differences in total deposited ink between consecutive font cells is minimized.

Abstract: Devices are known for measuring a subject's respiratory rate based on the subject's pulse wave or level of electrocardiogram. When the subject is exercising or carrying out daily activities, however, an electromyogram becomes imposed on the cardiogram waveform, so that a body motion component is superimposed on the pulse wave. This leads to an incorrect measured result. To overcome this drawback, a portable portion in the form of a wristwatch worn by the subject and a personal computer comprising device main body 330 are provided. A photoelectric pulse wave sensor is attached to the base of the subject's finger, and the pulse waveform is measured. An acceleration sensor is provided to the portable portion, and employed to detect the subject's body motion spectrum. Device main body 330 performs a window function on the pulse wave, and removes the acceleration component, so that the body motion spectrum is removed from the frequency spectrum of the pulse wave.

A detection state of the pulse wave sensor is also displayed by providing a detection state evaluator for determining the presence of a pulse wave component based on the result output by the pulse wave component extractor.

Abstract: An add-on cartridge structure for electronic devices having a housing formed from upper and lower case sections. The upper case is typically made from plastic and has a conductive layer formed on inside surfaces, while the lower case is made from a metallic material such as aluminum. A wall-like mating member is disposed on an outer edge of the lower case, and mates with the sides of the upper case to form a nearly rectangular cross section housing. The double conductive layer formed by the outside surface of the mating member and the inside surface of the upper case prevents leakage of electromagnetic radiation from the cartridge. Furthermore, high frequency noise is prevented by grounding both the signal ground of the printed circuit board and the frame ground at multiple locations. The conductive layer has a surface break caused by a through-hole through which the printed circuit board plug protrudes to the outside.

Abstract: In a measurement device and a measurement method for determining output values by analyzing the frequency of cyclically changing detection data, such as pulse count, the output value indicating a peak in the analysis result is corrected using side lobe values that appear on both sides of said peak, and an output value having higher precision than the output value indicating the peak value is derived, such that a value closer to the original output value of the detection data can be obtained. Because the measurement device and measurement method according to the invention can improve the precision of the output value without increasing the sampling count, highly precise output values such as pulse counts can be obtained at high speeds without extending the data fetch time.
