Filed: 1998-10-16
Abstract: The present invention relates to a system of program objects and program components and communication between program objects and program components. The present invention provides a program component with an external or send interface which enables message passing communication between a program component and different program objects. When a program component is loaded, the send interface of the program component is automatically exported to the send interface of the host object. This means that the send interface of the object is modified to contain the send interface of the program component.      Therefore it is possible to communicate by message passing between program components of a program object and other program objects.

Title: One-way actuation release mechanism for a system for applying medicament
Inventor: PY DANIEL
IPC: B05B11/00
Filed: 1998-12-17
Abstract: A medicament-dispensing system includes a cartridge for housing and actuating an accordion-like vial--dispenser for dispensing a calibrated amount of medicament by means of a single actuation motion which sequentially loads the vial-dispenser and dispenses the loaded medicament. The vial-dispenser has a front bellows portion, a rear bellows portion, an internal piston mechanism, a medicament storage chamber and a dosage cavity. The cartridge has a trigger mechanism which acts in concert with a notched lever and a wedge-shaped arm internally located in the cartridge to sequentially load the dosage cavity with medicament and discharge it. Depression of the trigger mechanism simultaneously extends, by means of the notched lever, the front bellows portion and compresses the rear bellows portion to load the dosage cavity with medicament. Once the notched lever has extended the front bellows portion a predetermined distance, the notched lever is disengaged from the front bellows portion by the wedge--shaped arm extending from the rear wall of the housing, thereby releasing the front and rear bellows portions, along with the internal piston mechanism, to return to original position and force the medicament from the dosage cavity via a nozzle of the vial-dispenser.

Inventor: BAJIC STEVAN
IPC: H01J49/04
Filed: 1998-04-28
Abstract: An ion source for a mass spectrometer operating at a low pressure has an atmospheric pressure sample ioniser which provides a sample flow containing desired sample ions. These ions are usually entrained with undesired gas and droplets. An interface chamber is held by a vacuum pump at a pressure between atmospheric and the operating pressure of the mass spectrometer. Sample ions with entrained gas are collected through an entrance orifice forming a stream of gas into the interface chamber.      Sample ions exit the interface chamber through an exit orifice to the mass spectrometer. The interface chamber disrupts the stream of gas entering the interface chamber to provide a dead region having no net gas flow direction and the exit orifice is located in this dead region. The exit orifice should have no line of sight path to the entrance orifice or should be at least 30° off the flow axis of the stream entering the interface chamber through the entrance orifice. A flow disrupting pin is located in the interface chamber to disrupt the flow of the stream of gas entering through the entrance orifice.

Patent CA-2263530-A1 (CA)
Inventor: SCHAACK DAVID F
IPC: A61B1/01
Filed: 1997-08-08
Abstract: Spatial locations of individual points on an inaccessible object are determined by measuring two images acquired with one or more cameras which can be moved to a plurality of positions and orientations which are accurately determined relative to the instrument. Once points are located, distances are easily calculated. This new system offers accurate measurements with any convenient geometry, and with existing endoscopic apparatus. It also provides for the measurement of distances which cannot be contained within any single camera view. Systematic errors are minimized by use of a complete and robust set of calibration procedures. A standard measurement procedure automatically adjusts the measurement geometry to reduce random errors. A least squares calculation uses all of the image location and calibration data to derive the true three-dimensional positions of the selected object points. This calculation is taught explicitly for any camera geometry and motion.

Inventor: SMITH HAROLD R JR
IPC: H04W4/90
Filed: 1999-05-04
Abstract: The system for auxiliary monitoring of emergency access calls functions to identify the geographical location of the origination point of the emergency access call and interconnects the appropriate emergency response agency that serves this geographic location to the emergency access call. The emergency access system is programmed to divide the covered region into a plurality of cells, with each cell defining a serving emergency agency and/or serving auxiliary emergency agency. Upon receipt of an incoming emergency call from a telephone station, the switching system determines the location from which the emergency access call originated, and which cell(s) define the serving emergency agency for this location. The system directs the incoming call to the designated emergency service agency as well as any serving auxiliary emergency agency that would be involved in the emergency response to the incoming emergency call. The identified serving auxiliary emergency agency would then be alerted in one of a number of possible ways: simple alert alarm without further data, listen-only bridging on to the incoming emergency call, two-way voice connection on incoming emergency call. The selected mode of alert enables the serving auxiliary emergency agency to either prepare to enable access to the appropriate emergency response agencies and/or actively participate in the response.

Title: Laser based method and system for integrated circuit repair or reconfiguration
Inventor: SUN YUNLONG
IPC: H01L21/768
Filed: 1997-10-29
Abstract: The present invention provides a method and system for irradiating resist material from multiple target positions (150) on one or more IC chips (12) with individually directed laser output pulses (74, 94). In one embodiment, an IC (12), including one or more etch targets (104, 106) such as conductive links (72, 92), is coated with an etch protection layer (90) of photoresist material. Then, position data direct, toward multiple positions (150) on the photoresist material, individual laser output pulses (94) of predetermined parameters selected to expose the photoresist material. Because photoresist exposure requires less energy than link blowing, low-power UV lasers (120) can be employed, and their shorter wavelengths permit a smaller practical laser output spot size (98). Because the nonablative process does not generate debris, an optical component (148) can be brought within 10 mm of etch protection layer (90) to focus the laser output pulses (94) to a spot size of less than two times the wavelength of laser output (140). Thus, an advantage of this embodiment permits microcircuit manufacturers to decrease the pitch distance (28) between circuit elements (14). After the photoresit layer (90) is developed, the accessible etch target (92) can be etched to repair or reconfigure the IC device. In another embodiment, slightly higher UV power laser output pulses (74) can be employed to ablate an etch protection resist layer (70) so any type of etch protection coating such as nonphotosensitive resist materials can be utilized with substantial manufacturing and cost benefits.  Etching of the accessible etch targets (60, 62) follows this process.
