Patent CA-2082065-C (CA)
Inventor: SITES RICHARD LEE
IPC: G06F9/44
Filed: 1992-03-04
Granted: 1996-09-03
Abstract: Information about the effects of calling each entry point in a program and information about external calls made by the program are recorded in an image information file. In addition to the addresses of the entry points and call destinations, the information may include any callback parameters and register usage associated with the entry points, and any definite values passed by the calls. When translating two separate but mutual-ly dependent programs that are not easily merged for simul-taneous translation, the image information files for the respec-tive programs permit the programs to be alternately translated with rapid convergence by an iterative method of checked as-sumptions and re-translation. By matching the addresses of the entry points of a first program with the addresses of the exter-nal calls for a second program, and by matching the addresses of the external calls in the first program with the addresses of the program entry points in the second program, the relevant externall calls and entry points in the image information file for the second program are identified. One program should be retranslated when a preceding retranslation of the other pro-gram changes the information for the matching calls and entry points in such a way that changed information might enable additional instructions to be discovered in the program under consideration for translation.

Abstract: A method of dispensing from a plurality of plastic shopping bags that are joined together in a series.  The method comprises rolling up the bags concentrically about a first axis to form a roll.  The formed roll has a pair of top straps of the outermost bag of the roll as the starting portion of the roll.  A pair of bars, spaced apart from each other one bar above the other, is provided.  At least one of the bars is provided with a snagging element transverse to a first direction of travel of the bags.  The snagging element permits passage of the panel portions of each bag past the snagging element in the first direction but it snags the transverse open top of each bag when pulled in the first direction by releasing the open top only when it is drawn between the bars in a second direction, transverse to the first.  Bags may be pulled in the first direction until the open top of the second bag reaches the snagging element where it is restrained.  The outermost bag is then pulled against the restraint to detach the bottom from the ensuing bag.  The transverse open top of the ensuing bag is pulled in the second direction, past the snagging element, and then in the first direction until the open top of the second ensuing bag is snagged by the snagging element for a repetition of the previous steps.

Title: Servocontrol for fiberoptic phototherapy pad
Inventor: KREMENCHUGSKY VLADIMIR
IPC: F21V8/00
Filed: 1994-02-09
Granted: 1999-03-23
Abstract: A system for controlling the amount of light radiation directed upon an infant from a fiberoptic phototherapy pad by feedback from a light detector that itself is afiberoptic pad. The fiberoptic detecting pad receives and detects the light density radiation over an area and is located intermediate the normal fiberoptic phototherapy pad and the infant and therefore is in the best position to detect accurately, the light impinging upon the infant. In some embodiments, the light detector pad is manufactured as part of the fiberoptic phototherapy pad itself as a unitary construction. Light readily travels through the light detector to the infant, yet the light detector senses the light intensity and density of the light passing therethrough.

Title: System and method for testing adequacy of human hearing
Inventor: ZUREK PATRICK M
IPC: A61B5/12
Filed: 1993-04-08
Granted: 2003-10-14
Abstract: Disclosed is a system and method for measuring hearing in which multiple single-frequency tones are presented by each of two transducer (64, 66), each transducer presenting only one single-frequency tone. One transducer is employed to present a plu-rality of f1 primaries, each in a different location of the range of audible frequencies, and the other transducer a plurality of corresponding f2 primaries, each having a frequency with respect to its corresponding f1 so as to make the ratio of frequen-cies suitable for the production of EDPs by that pair. By selection of an appropriate frequency far each primary in each set, a plurality of pairs may be presented to the ear simultaneously, without encountering the problems caused by the presence of numerous intermodulation products due to the interaction of the multiple primaries issued by the same transducer. This allows a single test to be performed that will simultaneously provide information about hearing function over a range of au-dible frequencies.

Title: Power supply circuit
Inventor: KONOPKA JOHN G
IPC: H05B41/392
Filed: 1993-07-15
Granted: 1998-05-05
Abstract: A power supply circuit (100) for use in driving fluorescent lamps (102, 104, 106) has a current mode control voltage boost IC (144) which produces a boosted voltage and has a power control input (pin 3) and a frequency control input (pin 4). The lamps are driven by a self oscillating inverter (178, 180, 196, 198) which is powered from the voltage boost IC and which operates at a frequency independent therefrom. In order to dim the lamps a D.C. bias voltage is applied to the power control input. At the same lime a commensurate D.C. bias voltage is applied to the frequency control input so as to provide power factor correction in dependence on the power produced by the voltage boost IC. The circuit thus provides a substantially constant, optimum power factor at both full and dimmed light levels.
