US Patent:

20010009416, Jul 26, 2001

Filed:

Mar 14, 2001

Appl. No.:

09/805617

Inventors:

Karl Robb - Fairfax VA, US

International Classification:

G09G005/00

US Classification:

345/179000

Abstract:

A pen cap stylus (or screen operator) is useful in combination with a conventional writing implement, such as a pencil or an ink pen. The manner in which the pen cap stylus screen operator engages to an end of a writing implement is analogous to how a pen cap engages either end of the pen for which it was designed. To form a hybrid instrument for use both as a computer stylus and as a writing instrument, the pen cap stylus is placed on the end of the writing instrument opposite the writing element. The pen cap stylus has a pointy tip for engaging a touch screen of a computer device to selectively actuate microswitches therein. The writing element disposed at the other end of the writing instrument maintains its conventional utility.

G06F 3/033

US Classification:

178 1901, 345179

Abstract:

A flexible stylus tip with a flat contact surface as disclosed herein can address the problems with touch devices and prior art styli. The flexible stylus tip can be formed of resilient material and dimensioned to grip the blunt end of elongated implements such as writing utensils or fingers so as to provide for increased user comfort and control. The stylus tip is hollow and formed of flexible material such as TPV. The tip has an open end with interior gripping rings to keep the stylus tip tightly secured on a pen or other elongated implement. The tip can be slightly graduated or tapered from base to end for optimal viewing of what is being activated on the screen. The contact surface of the stylus tip is flat and larger than other stylus tips to provide an increased activation area and improved ergonomics for touch devices.

Appl. No.:

9/579426

Inventors:

Karl Robb - Fairfax VA

International Classification:

G09G 500

US Classification:

345179

Abstract:

A screen operator or artificial finger tip for entering commands and data into a personal data device, such as an electronic notebook, by contacting the screen of the personal data device. The screen operator comprises a partially rigid base that encircles the finger, generally conforming to the finger, and a rigid tip member which projects forwardly from the base to contact the screen. The extreme tip of the tip member is of reduced diameter at the point of contact with the screen. The base is tubular (preferably with a gap) and resiliently grips the finger. A hook member extends downwardly and back from the tip member to engage the underside of the user's finger tip. The hook member functions to retain the screen operator on the user's finger tip.

Abstract:

An operator or artificial finger tip for entering commands and data into a personal data device, such as an electronic notebook, by contacting the screen of the personal data device. The operator comprises a partially rigid base which encircles the finger, generally conforming to the finger, and a rigid tip member which projects forwardly from the base to contact the screen. The tip of the tip member is of reduced diameter at the point of contact with the screen. The tip member has a snap fitting connector enabling it to be manually and removably attached to the base. The base is tubular and has a plurality of sockets, and the tip member has an equivalent number of male elements snap fitting to the sockets. Preferably, a plurality of tip members are provided, each differing from the others in diameter such that a selection of tip sizes varying in relative fineness at the point of contact with the screen is available to the user.
