The present invention relates to a method of calculating a surgical intervention plan. Based on surface data of the patient, a surface representation of a part of the patient's body is created. From a database, a plurality of surgical methods may be selected and the geometrical parameters of a surgical plan can be adapted based on each individual surgical method. Therefore, the surgeon may easily select, which of the surgical method is appropriate for the planned surgical intervention. Furthermore, the surgical intervention plan which has been adapted according to the finally selected surgical method may then be projected onto the skin of the patient such that a drawing of the incision lines is facilitated. Furthermore, the use of a remotely activatable pen based on the current position of the pen and based on the finally selected surgical plan is presented.

A multifunctional writing device includes a hollow body, wherein the hollow body comprises one or more cavities configured to store a mechanical pencil, a multifunctional drawing tool, a compass needle, a stylus, an eraser, a USB flash drive, an imaging system, a projector pen, a set of cameras, and attaches a projector stick. The first writing member comprises a mechanical pencil system being provided in a first portion of the hollow body and a touch ID sensitive barrel. A second projector member comprises a projector pen and attaches a projector stick. The first portion of the hollow body is at the opposite end of the second portion of the hollow body. The multifunctional writing device allows for projecting self-leveled and auto calibrated geometry drawing tools. A method for digitizing the written data on paper and a system for secure, auto proctored, and auto grading of examinations is provided.

An elongate hollow tube having two or more fidgets molded onto or attached to an outside surface of said tube is described. The tube can be slipped over a smooth elongated base object, such as a pencil or similar object, to provide manipulatives for students.

The present invention provides an electronic apparatus and an information processing method that allow a user who uses a writing tool to perform write actions such as writing a letter and drawing a picture to learn and improve skills while being highly motivated and having fun.

An electronic apparatus according to an embodiment of the present disclosure includes: a pen-type main body having a writing function or a main body attachable to a writing tool; a detection part provided in the main body for detecting frequency of a writing action of a user; a storage part for storing data including at least any of image data and numeric data; and a control part that performs control to select image data or numeric data from the storage part corresponding to the frequency detected by the detection part and to display an image based on the selected image data or numeric data on a display part.

A manual device including a first portion and a second portion. The second portion being at least partially fitted into the first portion and being moveable in translation relative to the first portion. The first portion having a first distal end while the second portion has a second distal end opposite the first distal end. The second portion also includes a locking device designed to prevent the first portion from moving in translation relative to the second portion only when, considered in the direction of gravity. The first distal end is arranged above the second distal end, and the locking device includes a chamber and a ball or equivalent accommodated in the chamber. The chamber is provided only in the second portion.

A germ-reducing pen container including a body having a hollow passageway extending therethrough from an insertion end to a distal end for receiving a pen, the hollow passageway having at least one ultraviolet C light operatively attached thereto, an indicator on an outer surface of the body, and a dispensing mechanism operatively attached at the insertion end for dispensing the pen. A method of reducing germs on a pen, by inserting a pen into a body of a germ-reducing pen container, applying ultraviolet C light to the pen, killing the germs on the pen, indicating that the pen has been cleaned, and dispensing the pen.

A scented flower writing utensil arrangement has a vase, an artificial floral arrangement, a quantity of simulated water medium, a scented core, a writing utensil holder, and a plurality of decorative writing utensils. The quantity of simulated water medium is a self-curing agent at the base of the vase within which the stems of the artificial floral arrangement are affixed. The scented core and the writing utensil holder are disguised within the artificial floral arrangement. The scented core is a sponge or similar material to which scented oil is applied. Each of the plurality of decorative writing utensils has a flower end opposite the writing end, and is placed into the writing utensil holder.
