Title: Computer display screen simulation for optometric examination
Inventor: SALIBELLO COSMO
IPC: A61B3/02
Filed: 1993-02-24
Abstract: COMPUTER DISPLAY SCREEN SIMULATION   FOR OPTOMETRIC EXAMINATION                        ABSTRACT OF THE DISCLOSURE   An improved vision tester apparatus and method are disclosed for use in conducting optometric examinations of patients who use video display terminals (VDTs). Specifically, the tester simulates images that are displayed to the patient by a typical VDT, so as to facilitate prescribing corrective lenses that will perform well for the patient when used with an actual VDT. The tester (10) includes a flat-panel electroluminescent light source (32) for illuminating a screen (14) without hot spots. The screen includes a colored ink layer (78,80,82) and an opaque ink mask (70) for forming pixel-like light elements (24). Lensing structures (52,56,58,60) degrade the image such that each light element exhibits a generally Gaussian light amplitude curve (FIG. 5B) characteristic of a pixel of an actual VDT. A rechargeable battery (34) coupled to a inverter circuit (30) provide portable power for the EL panel to complete a compact, portable tester.

Title: Condensing unit using cross-flow blower
Inventor: LIM ALEXANDER T
IPC: F24F1/38
Filed: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention involves split system air conditioners.   Specifically, the present invention provides a condenser unit with cross-flow blowers.  A single cross-flow blower may be used to draw air through a heat exchanger and expel the air adjacent to a cut-off portion.  Further, dual cross-flow blowers may be provided to enhance the performance of the condenser unit.  The combination of air streams from two cross-flow blowers provide better air circulation through the heat exchangers and a more uniform exhaust stream.   The condenser unit is more compact and can be mounted on the wall, on the overhang, or on the top of the building.  These various mounting locations take advantage of the air boundary layer near the building and thus the air conditioning system operates more efficiently.

Inventor: BENSON CARL L
IPC: A61M5/32
Filed: 1993-10-08
Abstract: A needle stopper for use with a hypodermic syringe such as an arterial blood gas syringe includes a shell having a bottom, an open top and a needle-receiving chamber therebetween. The bottom is configured to support the needle stopper in an upright orientation. The needle-receiving chamber is dimensioned to receive needle cannula and to engage a needle hub connected to the cannula. The chamber is at least partly filled with a sealing material that can occlude the tip of a needle cannula. The upright orientation of the needle stopper enables one-handed insertion of the needle cannula into the needle-receiving chamber for occluding the needle tip. Engagement of the needle stopper with the needle hub enables safe and convenient separation of the needle hub and cannula from the syringe barrel for disposal. The tip of the syringe barrel then may be capped and sent to a laboratory for analysis of fluids therein.

IPC: A61M25/10
Filed: 1992-04-21
Abstract: 2109095 9218195 PCTABS00016 A perfusion balloon catheter which permits blood flow through the balloon even when the balloon is inflated. The balloon catheter comprises a thin-walled, collapsible and inflatable tube (32) that has a proximal, generally straight portion, and a distal, helically coiled portion that is generally cylindrically shaped and defines an open lumen (34) therethrough. The successive turns of the coil are secured to one another (45) to maintain the balloon's configuration when inflated. The furled balloon catheter can be inserted to the desired location and then inflated. Because the helically coiled portion defines a relatively large open lumen (34), blood flow through the balloon can continue even as the inflated balloon remains in place, facilitating extended inflation periods.

Abstract: The invention relates to cap or booster sensitive explosives for application in bulk or cartridge form in boreholes. The oxidizing salt of the explosive is ammonium nitrate, sodium nitrate and/or calcium nitrate having untamped bulk density of 0.3-0.75 g/cm3.     The explosive according to claim 1 can be a w-i-o emulsion explosive where the discontinuous phase is an aqueous solution of the oxidizing salts and where low density ammonium nitrate comprises 10-30 weight% of the total explosive. ANFO, HANFO and water-gel explosives comprising said oxidizing salts having untamped bulk density of 0.3-0.75 g/cm3 are examples of explosives according to the invention. The above types of explosives are especially suitable in small and medium size boreholes without using sensitizing or density reducing agents.

Abstract: 2129346 9315496 PCTABScor01 A method and optical system auxiliary input calibration arrangement (10A) accurately and reliably discriminate between a user generated image and a video source generated image, such as one produced by a computer. The calibration arrangement includes amplifier devices (176a) for increasing the strength of a video information signal (178A) indicative of the video generated image, and a user generated auxiliary input signal (179A) indicative of an auxiliary input light image, without increasing spurious ambient light signals. A discrimination circuit (46A) generates a detection signal whenever the amplified information signals are greater than a predetermined reference level signal. The microprocessor (42A) controls the exposure time of the light sensing device and selects an appropriate level of amplification for the output signal from the sensing device to increase light sensitivity between the vieo source generated light images as compared to the user generated auxiliary light images. The optical auxiliary input arrangement (11B) accurately and reliably discriminates between user generated double click information without the need of the user being so steady of hand as to cause the auxiliary light information beam to illuminate the same precise location on the viewing surface during the double click operation.
