Inventor: DENNO RODNEY G
IPC: G06F21/60
Filed: 1992-09-11
Abstract: ABSTRACT OF THE DISCLOSURE         A secure terminal is disclosed which has a single keypad and display which is suitable as a debit terminal, as both confidential and nonconfidential information can be entered.  Confidential information is entered in secure text mode whereas nonconfidential information is entered in clear text mode.  The terminal defaults to secure text mode where all information is encrypted.  In clear text mode all prompts are independently authenticated by a secure module prior to displaying of the prompt.  Prompts for clear text mode are preprogrammed preferably with an Authentication Parameter which is confirmed by the secure module whenever that prompt is used in clear text mode.  The invention is also directed to the methods for rendering a terminal and system secure for receiving confidential and nonconfidential information.

Patent CA-2094868-A1 (CA)
Inventor: MICHIKOSHI HISATO
IPC: G02B6/32
Filed: 1993-04-26
Abstract: An improved semiconductor laser module is provided herein which is used for transmitting signals by optical fibre in optoelectronic communication. This improved semiconductor laser module includes a semiconductor laser for emitting light beams; a lens for converging the light beams, a lens holder having an axial bore for keeping the lens in the axial bore and the semiconductor laser at an end of the axial bore, and an optical fibre. A ferrule holds an end of the optical fibre. A receptacle which has an axial hole therein supports the ferrule, the receptacle being connected to the lens holder. A transparent block having non-parallel front and rear surfaces is fixed in the axial hole of the receptacle, the transparent block being separated from the end of the fibre. In this way, the deviation of axes between the receptacle and lens holder is small enough, and assembly is easy. In addition, the coupling between the receptacle and lens holder has strong mechanical strength. This solves the existing problem of contamination of the transparent block by adhesion of dust which deteriorates the performance against noise induced in the laser by the return of the beam.

Title: Method and apparatus for detecting double fed sheets
Inventor: CHANG SUNG S
IPC: B65H7/12
Filed: 1993-10-06
Abstract: A method and apparatus for detecting double fed sheets.      A sheet passes beneath a roller which is mounted on a lever so that the opposite end of the lever is deflected by an amount proportional to the thickness of the sheet. A magnet is attached to the opposite end of the lever approximate to a Hall Effect sensor fixed to the frame of the apparatus so that the hall sensor produces a signal proportional to the thickness of the sheet. The output of the hall sensor is sampled by an A/D convertor and the signals are input to a computer for processing to detect double fed sheets. Average thicknesses for subsequences of samples distributed over the sheet are computed and compared to reference levels. The length of the sheet is also compared to a reference length.      If, for any of these comparisons the measured values are greater than the references a doubled detect signal is generated. In one embodiment leading and trailing edges of the sheet may be detected by detecting transitions in the sequence of signals which are greater than the design minimum sheet thickness. In another embodiment of the subject invention the reference levels are established by first measuring a selected, assured single, initial sheet. In another embodiment of the subject invention the references are updated after each sheet by combining a portion of the previous reference value, preferably 7/8th's, with a portion, preferably 1/8th, of the measure value multiplied by an appropriate scale factor.
Patent CA-2110343-A1 (CA)
Inventor: CHEH CHRISTOPHER H
IPC: B01D59/26
Filed: 1993-11-30
Abstract: A gas chromatographic method utilizes columns having either ascending or descending temperature profiles to effect separation even under column overloading conditions. A fixed ascending temperature profile column allows for good separation of components of a mixture under conditions of column overloading. A mixture to be separated is chromatographed on at least one such column prior to chromatography on a column maintained with a descending temperature profile. This latter column has surprisingly been found to greatly reduce tailing of less volatile species. The invention also includes a variable temperature descending column chromatography to provide an initial ordering of a large quantity of components prior to chomatography on the fixed ascending temperature profile column, or on the serial fixed ascending and descending temperature profile pair of columns.

Patent CA-2114374-A1 (CA)
Inventor: UMETSU MASAKAZU
IPC: G06F13/364
Filed: 1994-01-27
Abstract: When a first bus master device issues a bus request on a first request signal line, a centralized arbitration circuit in a system bus manage circuit issues a bus grant signal on a first grant signal line if the bus is available for use. This causes the first bus master device having gained the ownership of the bus to issue a read request to a first slave device. At this time a first signal line is designated. Even before the sending of the read data constituting a response to this read request to the first bus master device, a bus request from a second bus master device can be accepted if the data bus is unoccupied.   Thus, the centralized arbitration circuit in the system bus manage circuit issues a grant signal on a second grant signal line. This causes the second bus master device having gained the ownership of the bus to designate a second end signal line, and to issue a read request to a second slave device. After that, the first end signal line is activated, and read data from the first slave device is sent to the first bus master device. On the other hand, the second end signal line is activated, and read data from. the second slave device is sent to the second bus master device.

Filed: 1994-02-09
Abstract: ABSTRACT OF THE DISCLOSURE      A device, adaptable to a forklift, for grasping a storage drum by a lip formed in its top edge.  A lifting arm supports the lip from below while a mechanical linkage causes the spring-loaded support arm to be drawn against the inside surface of the lip as the device is raised by the forklift.  Further lifting by the forklift causes the drum to be raised while the force exerted by the holding arm against the lip is dictated by the weight of the drum.  Lowering the drum to the ground causes the mechanism to automatically release.
