Abstract: This disclosure describes a zinc-free lubricating oil composition. The composition includes a major amount of an oil of lubricating viscosity having a kinematic viscosity at 100° C. in a range of about 1.5 to about 35 mm2/s and an anti-wear mixture having one or more ashless dispersants and an alkyl phosphonic acid having a structure given by wherein R is a C3-C20 hydrocarbyl group. The initial pH of the anti-wear mixture is between 5-9.5 as measured by ASTM D664.

Abstract: An image with a bright image plane can be photographed without deteriorating the yield. An object is photographed by a CCD (18) through each of plural filters (141-14N) that have optical films vacuum deposited thereon so that spectral transmission characteristics vary between the filters periodically. Image data obtained by photographing is converted into image data which corresponds to a band by using a plurality of coefficients for converting the spectral transmission characteristics of the filter into spectral transmission characteristics of the target band.

Abstract: A region-in object measuring system comprises a reference object (1) having two frames, i.e., an object surface frame (2) brought into contact with the surface of an object and a film frame (3) with which an X-ray film (7) is brought into contact, spaced from each other and a computing device.

Abstract: A given visual field is divided into a plurality of areas, and brightness information in the areas is detected at predetermined time intervals and stored as information of a mobile body in a memory of a motor vehicle monitoring apparatus on a motor vehicle. The bright information detected in the areas at different times is then read from the memory, and a motion of the brightness information between adjacent ones of the areas is detected as a one-dimensional optical flow. The detected one-dimensional optical flow is compared with a one-dimensional optical flow generated from a road due to the speed of the motor vehicle, for thereby detecting another motor vehicle which is moving toward the motor vehicle.

Abstract: In order to obtain a clear surface pattern of an object such as a fingerprint impression and the like, a surface of an optical element against which the object is impressed is made of an elastic and/or viscous material. Thus, a surface pattern with high contrast is available even if the surface to be imaged is dry.

Abstract: A method and apparatus for matching fingerprints is provided in which the collation rate is improved by using both characteristic and non-characteristic minutia for the collation process. An image processing unit used in the apparatus cannot determine whether the collation minutia searched are characteristic or non-characteristic since an IC card holds a list of collation minutia records, thus offering improved security. Further, random numbers may be utilized for accessing the collation minutia record list for further improved security.
