US Patent:

6511420, Jan 28, 2003

Filed:

Aug 6, 1999

Appl. No.:

09/370646

Inventors:

Richard A. Farrell - Laurel MD
Russell L. McCally - Columbia MD

Assignee:

The Johns Hopkins University - Baltimore MD

International Classification:

A61B 104

US Classification:

600167, 600162, 600200, 351205

Abstract:

A hand-held ophthalmoscope modified by the removal or augmentation of the focusing wheel and the addition of a manual or automatic focusing lens system. An electronic imager (CCD array or video camera) is placed optically conjugate to a viewing screen such that focus operations performed by the examiner to adjust the image seen by the examiner on the screen also focuses the image on the electronic imager. This is accomplished by an optical system which includes a straight path from the viewing screen to the patients eye with a beam splitter interposed to cause the image of the patients eye to be reflected onto the imager. As a result, when the examiner uses the focusing lens system, manual or automatic, positioned between the beam splitter and the patients eye, to affect the image viewed by the examiner, the focus of the imager is simultaneously affected as well. Alternatively, the image from the imager is sent to a liquid crystal display (LCD) in the instruments eye piece; when the examiner focuses the image on the LCD, the image on the imager is focused simultaneously. Also provided is an automatic focusing system for the imager that operates independently of the examiners focusing adjustments.

An automatic focusing system for the imager can also be incorporated in the other two embodiments. The output from the electronic imager can be in digital or analog form and can consist of a single frame or a video stream.

Appl. No.:

7/248824

Inventors:

Richard Soloway - Lido Beach NY
Richard Farrell - West Babylon NY

International Classification:

H01H 1370

US Classification:

200 5A

Abstract:

A modular snap-in keypad apparatus includes a planar frame member having a plurality of button accommodating apertures and a plurality of mounting posts extending therefrom. An elastomeric key button assembly has a planar surface containing a plurality of apertures which are positioned to receive each post. The button assembly comprises a plurality of raised elastomeric button structures which extend through an associated button accommodating aperture when said posts of said frame assembly accommodates the apertures in the button assembly. A planar switch assembly has a plurality of apertures which are congruently positioned with respect to the posts to enable the contact assembly to be positioned with respect to each button so that a conductive area of the button contacts the contact assembly when the button is depressed. The contact assembly is fabricated on a Mylar sheet and has a contact area which consists of an outer partial circular contact having inwardly disposed triangular projections and an inner T-shaped contact. When a button is depressed the inner T-shaped contact contacts the outer circular contact by means of the conductive area of the button.

International Classification:

A47B 8800

US Classification:

312201

Abstract:

A detection system is disclosed for a mobile storage system which causes the storage system to prevent movement of a storage element whenever a person is detected in an aisle between storage elements. The detection system uses a presence or motion detector for detecting the presence of a person in an open aisle without direct contact between the person and the detection system. Preferably, a radar transceiver operating in X-band is positioned to overlie each open aisle to detect presence of movement of a person in an open aisle, even slight movement such as breathing. The storage system in which the detection system is connected prevents any closing movement of a storage element adjacent an aisle in which a person is detected so as to avoid frightening the person in the aisle.

Appl. No.:

5/831807

Inventors:

Richard Farrell - Williston Park NY

International Classification:

B65D 6132

US Classification:

366192

Abstract:

The pneumatically operated apparatus includes a transparent, calibrated paint container to facilitate measuring of the required proportions of color and solvents. A vertically displaceable and rotatable member extends through and seals an opening in the bottom of the container. The member has a hollow body forming a paint passage. An agitator is sealingly mounted on the end thereof extending through the opening and into the container, the other end being opened. An aperture is provided in the wall of the member spaced a short distance from the agitator. A friction surface is provided for connecting a pneumatically operated drive to the member to rotate same. The member is vertically displaceable between a mixing position, wherein the friction surface is effective to engage the member and rotate same and the aperture is situated below the container seal to prevent paint flow and a dispensing position, wherein the friction surface is disengaged from the member and the aperture is at least partially situated above the seal in the container, so as to provide a passage to permit gravity to cause the paint to flow through the body and out the bottom opened end thereof.
