HEATED WRITING DEVICE FOR USE WITH THERMOCHROMATIC INK
20170274699 · 2017-09-28 ·

The present disclosure relates to a device for activating thermochromatic ink. The device may include a drawing tip, a heating element, which may include a positive temperature coefficient (PTC) heating element, communicably coupled to the drawing tip and configure to heat the drawing tip, and a power source configured to provide power to the heating element. The power source may be a lithium-ion battery. The battery may be rechargeable, and the device may have a charging port to recharge the battery from a power source coupled to the charging port. The device may have a regulator for regulating power from the power source to the heating element. The device may have a controller for directing power from the power source to the heating element. Further the heating element may be configured to heat the drawing tip to a temperature between 30-70 degrees Celsius.

Multifunctional illuminated lighting pad
11448887 · 2022-09-20 ·

A multifunctional illuminated lighting pad is an apparatus that enables a user to write with one hand, rather than requiring a hand to hold a clipboard or writing surface and another hand to write down information. The apparatus provides a mechanism by which to secure to a user, thus preventing difficulty or danger resulting from a loose clipboard. An illumination source provides ample light, allowing the user to read and write in otherwise poorly-lit areas. A portion of the opaque backing may be secured to a user's pocket and molded to the rough curvature of a leg. An exposed portion of a backing surface holds a writing surface, an LED, and a clip. A thumb-pull cut allows the user to insert or remove a reference sheet from between the plexiglass front plate and the backing, thus allowing the user to refer to information behind the plexiglass front plate while writing.
