    摘要: The present invention determines whether fingerprint ridgeline information is contained within the fingerprint image using a simple method by considering the properties of the fingerprint ridgeline. In this fingerprint image evaluation method, a density is obtained of a reference point provided within the fingerprint image and a density is obtained of a comparison point that is shifted from the reference point by a predetermined distance. The amount of fingerprint ridgeline information contained within the fingerprint image is evaluated based upon a difference between the density of the reference point and the density of the comparison point. In this fingerprint image evaluation method, the characteristic of the fingerprint ridgeline, in which a fingerprint furrow line exists proximally to the fingerprint ridgeline, is utilized. Therefore, erroneous determinations can be prevented in which an image, which is not in fact a fingerprint image, is determined to be a fingerprint image. In addition, it is only required to obtain the density of the reference point and the density of the comparison point, and to calculated their difference. Therefore, time consuming processing is not necessary, such as is required to extract characteristic points from a fingerprint image.

    摘要: A pressure- and temperature-sensitive transducer comprises a tubular housing, a resonator located within the housing and end caps closing the ends of the housing. The resonator is located in a radial plane with respect to the housing and is connected to the housing by two separate connecting regions. The housing, resonator and connecting, regions are formed from a single piece of double rotation cut quartz. The shape, dimensions and position of the connecting regions is chosen to optimize stress in an axis responsive to changes in pressure and temperature while minimizing stress in an axis responsive predominantly to pressure.

    摘要: The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve. The dispenser further includes a main body with a second outlet valve. When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves. The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap. As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir to the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilient release is preferably normally provided with a stop which must first be moved out of the way. This is to prevent the user from accidentally disconnecting the reservoir when what is really wanted is a dispensation of soap. Should the reservoir be disconnected, pushing in and releasing the plunger will not result in the first outlet valve to open, because pressure will not be lowered in the metering chamber when the plunger is released.

    摘要: A minute amplitude value emphasis device 2 has Fourier transformation devices 211, 212 which treat a two-dimensional original pictorial image 200 with a Fourier transformation to determine Fourier coefficients in x-axis and y-axis directions. Weight devices 221, 222 emphasize the respective Fourier coefficients in the corresponding directions so as to produce weighted Fourier coefficients. Inverse Fourier transformation devices 231, 232 treat the weighted Fourier coefficients with an inverse Fourier transformation in two directions to determine the corresponding minute amplitude value emphasis data 241, 242. A synthesizing device 250 synthesizes the corresponding minute amplitude value emphasis data 241, 242 to produce a minute amplitude value emphasis image 260. An obscure portion of the two-dimensional original pictorial image 200 is rectified to reproduce a clarified pictorial image.
