Abstract: A self-propelled trolley and supporting track structure, the trolley forming a housing for a four wheel drive mechanism which is coupled to a driving motor attach-ed to the housing and to a pair of axles each equipped with a pair of driving and supporting-wheels adapted to engage transversely spaced track surfaces of the track structure. The track structure comprises a pair of transversely spaced channel section track members, each having upper and lower flanges terminating in guide surfaces and connected by a vertical web, the guide surfaces of one track member facing the guide surfaces of the other.  The track surfaces are formed by the upper flanges of the track members and the guide surfaces are engageable by pairs of guide wheels appended to the trolley below the housing.  A conductor bar assembly enclosed within the track members is engaged by collector shoes attached to the trolley.

Abstract: There is provided a sensing system using optical fibers having loss characteristics subject to variations for a signal light wave as a pumping light wave with a wavelength different from that of a signal light wave is coupled into said optical fiber.  Unlike conventional OTDRs that utilizes a light back scattering in an optical fiber, a sensing system using optical fibers according to the invention utilizes the light passing through an optical fiber as a detected signal in order to enhance the efficiency and effectiveness of the system and therefore it has a significantly improved S/N ratio and a dynamic range of measurement as compared with those of conventional OTDRs.  Moreover, continuous light may be used for the signal light wave (detected signal) to increase the rate of light emission for detection and to reduce the time required for measurement, providing remarkable advantages of the system when used for industrial applications.

Abstract: ABSTRACT OF THE DISCLOSURE         An image reading apparatus in which automatic gain control  is  performed  comprises  a  integral reading  unit, integrated with an optical system having a light source for irradiating an original, a rod lens array for focusing an image, and a line image sensor for reading the image, and a white reference plate, as a reference image upon reading of the image, being attached on one end of reading unit so as to move together therewith.  There is effect in that one and the same portion of the white reference plate is read by the line image sensor so that the gain control can be made on the basis of the output of the line image sensor.  Further even if a part of the white reference plate becomes dirty, an even output can be obtained throughout the whole surface of the original to thereby make it possible to prevent deterioration,  such as generation of transversal stripes, from occurring in the output picture.

Granted: 1997-01-07
Abstract: A method of mandatorily enforcing security protections to insure access to files of a computer system only to computer processes properly authorized foraccess. A separate security label is associated with each file and process of the system and defines authorized security classes pertaining to the associated file or process. Each security label contains information describing authorizations based on data secrecy and data integrity. A comparison is made on an attempted access of a file by a process of the security label associated with the process and the security label associated with the file. A verification is made based on the comparison that the process is authorized to access the file. The verification as to both secrecy and integrity aspects is accomplished in the single verification step.

Patent CA-2032413-C (CA)
Inventor: ENGELKE HELMUT
IPC: G03F1/20
Filed: 1990-12-17
Granted: 1996-03-05
Abstract: For the fabrication of semiconductor chips with an increasing number of electrical elements it is necessary that the geometry of the elements becomes smaller and smaller. For that purpose, lithographic techniques have been developed using x-rays, electron or ion beams. Especially for particle beams, self-supporting masks are stringent with the consequence that it is not possible to fabricate, for example, a ring-shaped structure with one mask. This mask stencil problem is solved by exposing the chip with two complementary masks. The present application relates to a method for automatically splitting one layout into two complementary patterns for the two masks. The method determines all corners of the layout which extend into a hole representing area of the masks. A stability criterion is carried out for the corners, with the consequence that only unstable corners are used for cutting the hole representing area into sections. Subsequently the sections are distributed onto the two patterns alternatively.

Title: Power conserving technique for a communications terminal time slot interchanger
Inventor: EAMES THOMAS R
IPC: H04Q11/08
Filed: 1991-07-10
Granted: 1997-04-01
Abstract: A communications terminal interfaces a large number of potential  individual telephone subscriber channels with a wide bandwidth, time multiplexed fiber optic  or other type of trunk line.   A time  slot interchanger within the terminal assigns each of the subscriber channel time slots to one of the time slots in the trunk line signal.  Data of the individual time slots of a frame of data of all channels is sequentially stored in a random access memory and then read out in a different sequence.  A uniquely addressed location is provided in the memory for data of each individual channel.   For cases where all channels are not being utilized, the system omits reading and/or writing data into the corresponding memory data locations not being used, thus saving power.
