Patent CA-2102756-A1 (CA)
Title: Universal display
Inventor: HARNELL RICHARD
IPC: G06F3/02
Filed: 1993-11-09
Abstract: A B S T R A C T A data terminal comprises a base module and a portable module. The base module is provided with a receptacle into which the portable module can be plugged by a simple sliding action. A lock is provided to mechanically lock the portable module to the base module. The actuation of the mechanical lock also serves to actuate an electrical switch to connect or disconnect power to the portable module, and a circuit to retain power in the portable module in the event that the switch is actuated prior to the appropriate closure of any program being run so as to avoid loss of data. The receptacle is hinged to the base module, and a detector is incorporated to provide a signal indicative of the angle of inclination of the receptacle, which signal may be used to alter the contrast of a video display screen in the portable module. The display screen is allied with a touch screen. Drift and parallax are monitored continuously, determining vector differences between central key areas mapped onto the touch screen and the area of touch within a key area, which differences are sampled and averaged to establish statistical trends, and an appropriate offsetting signal is provided to the touchscreen controller.

IPC: G06F12/0875
Filed: 1993-08-10
Abstract: ABSTRACT            CACHE ARCHITECTURE FOR HIGH SPEED MEMORY-TO-I/O                       DATA TRANSFERS            Computer   architecture   and   method   of   control   for accomplishing  low  speed  memory  to  high  speed  I/O  data transfers. An I/O cache is connected between the memory data bus and a system  I/O data bus,  and is responsive to  a storage control unit which manages data transfers over the system I/O bus.  The relatively lower speed of the system memory is offset by the larger size of the memory data bus in comparison to the system I/O data bus. The I/O cache is used to prefetch memory data  during  read cycles,  which prefetch  operates  in  concurrence  with the  transfer  of previously prefetched data from the I/o cache to I/O control units on the system I/O data bus. During the writing of data from I/O to system memory,  the  I/O cache buffers memory access  interferences  initiated  by  the  processor.  The invention permits the use of a conventional and relatively slow main memory in conjunction with a high speed processor and high speed I/O system.

IPC: B61D45/00
Filed: 1993-09-28
Abstract: An improved articulated railway spine car unit for carrying highway truck trailers and/or containers has a center sill which extends substantially the entire length of the car unit. The center sill has end portions with upper surfaces depressed with respect to the upper surface of a longitudinally extended center portion. A retractable fifth wheel or trailer hitch is located on the upper surface of at least one end portion of the center sill. The upper surface of the trailer hitch, when retracted onto the center sill, is at substantially the same level as the center portion of the center sill.      The raised center sill center portion both provides back-up support for the floors of containers carried on the car unit, and also increases the center sill's structural rigidity and resistance to bending deflection. Stowable container locks extending through trailer wheel decks on the car unit are provided with pivotable covers which cover the locks and associated wheel deck openings when the locks are stowed, and secure the locks in their upright position when a container is to be mounted thereon.

Title: Illuminator and method for photodynamic therapy
Inventor: ZARATE CARLOS E
IPC: A61N5/06
Filed: 1993-10-18
Abstract: An illuminator for photodynamic therapy includes a bulb, a condenser lens assembly and a filter assembly.      The filter assembly includes the following components in an optical path: (1) a high-pass filter to filter out light having wavelengths below a first wavelength value; (2) a low-pass dichroic filter to filter out light having wavelengths above a second wavelength value; and (3) a dichroic mirror which reflects light having wavelengths between the first wavelength value and the second wavelength value and which transmits infrared light. An exit lens assembly directs light transmitted through the high-pass filter and the low-pass dichroic filter and reflected by the dichroic mirror onto a patient for photodynamic therapy. The condenser lens assembly and the exit lens assembly scramble the beam to ensure that the patient is illuminated with light which is highly uniform in both intensity sand spectral characteristics (color) throughout the illuminated area.

Abstract: In an elevator system comprising an elevator car, a counterweight, a set of elevator suspension ropes on which the elevator car and the counterweight are suspended,  a traction sheave whose motion is transmitted via the suspension ropes  to the  elevator  car  and to the  counterweight,  a compensating system includes a set of compensating ropes connected to the elevator car and the counterweight via at least one diverting pulley.  A vertically adjustable buffer arrangement mounted in conjunction with the counterweight allows the system to compensate for changes in the length of the suspension and compensating ropes.  The suspension ratio of the compensating ropes is an integer multiple (i.e. 1, 2, 3 etc)  of the suspension ratio of the suspension ropes. Finally, the rope suspension ratio on the side of the elevator car can be the same as that of the counterweight, or it may be different.

Filed: 1994-06-27
Abstract: Abstract The invention relates to a novel process for producing a stick of adhesive, which has a rotatable base part with rotary spindle,  said spindle engaging in a holding device for the stick material (plunger,  small basket,  anchoring disc)  and the holding device being fitted into a sleeve surrounding the stick material. By means of the rotary spindle, the stick-shaped adhesive material can be moved up and down. According to the invention, the sleeve (2) together with the plunger (1) forms a one-part injection moulding which is joined, via predetermined breaking points (3), to the sleeve wall. For the assembly, the base part with rotary spindle is pushed through a recess, arranged so as to be centred, in the plunger until the lower periphery of the sleeve comes to rest against the upper part of the base part, then the stick material is poured into the unit thus formed, comprising sleeve, plunger and base part with rotary spindle, and, after the filling operation is complete, the rotatable base part is actuated and as a result the plunger is lifted into the intended end position (10) with tearing off of the predetermined breaking points.   The invention also relates to an arrangement for carrying out the process, consisting of a) a rotatable base part (7), a rotary element (7B) and a rotary spindle (7A), the base part having two support plates (9A, 9B), and b) a one-part injection moulding, comprising a sleeve part (2) which is open at both ends and a plunger (1) with predetermined breaking points (3) (Fig. 1)

Title: Comparative genomic hybridization
Inventor: PINKEL DANIEL
IPC: C12Q1/68
Filed: 1993-03-01
Abstract: Disclosed are new methods comprising the use of in situ hybridization to detect abnormal nucleic acid sequence copy num-bers in one or more genomes wherein repetitive sequences that bind to multiple loci in a reference chromosome spred are either substantially removed and/or their hybridization signals suppressed. The invention termed Comparative Genomic Hybridization (CGH) provides for methods of determining the relative number of copies of nucleic acid sequences in one or more subject ge-nomes or portions thereof (for example, a tumor cell) as a function of the location of those sequences in a reference genome (for example, a normal human genome). The intensity(ies) of the signals from each labeled subject nucleic acid and/or the differences in the ratios between different signals from the labeled subject nucleic acid sequences are compared to determine the relative copy numbers of the nucleic acid sequences in the one or more subject genomes as a function of position along the reference chromo-some spread. Amplifications, duplications and/or deletions in the subject genome(s) can be detected. Also provided is a method of determining the absolute copy numbers of substantially all RNA or DNA  sequences in subject cell(s) or cell population(s).
