Disclosed is a pen for writing, referred to as a palm pen herein because the body of the pen fits into the palm of a human hand. The palm pen can include a spherically shaped body, and an ink delivery system. The ink delivery system can include a tip having an end connected to the body and an opposite end comprising a nib, an ink conduit having an end coupled to the nib within the tip and an opposite end extending inside the body, and a first ink cartridge fluidly coupled with the opposite end of the ink conduit and contained within the body. The ink delivery system can additionally include a cartridge holder having an active cartridge slot for the first ink cartridge and cartridge storage slots for storage of additional ink cartridges.

A multi-function pen includes a cap; a metal body connected with the cap, where a first accommodating cavity is formed between the metal body and the cap, an outer wall of the metal body is provided with a gap for opening a bottle cap, and the gap is disposed below the first accommodating cavity; a light emitting structure accommodated in the first accommodating cavity; a nib in threaded connection with the metal body, where a second accommodating cavity is formed between the nib and the metal body; and a refill accommodated in the second accommodating cavity. The multi-function pen can meet the basic working demands of electricians and woodworkers, and is small, light, convenient to be put in pockets of operators and practical.

Aspects of the present invention relate to external user interfaces used in connection with head worn computers (HWC).

A writing instrument, comprising a tubular body having a longitudinal axis with a first and a second end, and with an opening arranged in the first end; a first building block having a body part with a substantially plane surface and one or more coupling knobs extending from the substantially plane surface, and where the first building block is fixed onto the outside of the tubular body so that the coupling knobs extend away from said longitudinal axis.

Provided are a mechanical-pencil cap serving as a touch-pen tip and a pencil-lead sharpener, and a mechanical pencil having the mechanical-pencil cap. The mechanical-pencil cap includes a front fixing part (11b) for the touch-pen tip formed in a shape of a truncated conical recess, and a pencil-lead sharpener functioning part (11c) provided to be opposite to the front fixing part (11b) for the touch-pen tip, and connected to the touch-pen tip (11f) formed to surround an outer circumference of a touch-pen tip fixing member (11e). This enables an input operation into a mobile terminal, such as a smartphone or a smart pad having a capacitive touch screen, to be performed in a touch manner, and allows a pencil lead inserted into a pencil-lead insert container and ejected out when in use to be conveniently sharpened without the necessity of separating the pencil lead.

Aspects of the present invention relate to external user interfaces used in connection with head worn computers (HWC).

A multifunctional pen includes a penholder and a refill provided in the penholder. A clip is provided on the penholder. The penholder comprises an upper penholder and a lower penholder hinged to each other. The lower penholder may bend and tilt toward the upper penholder through a hinged joint. The clip is arranged on the upper penholder and across the upper penholder and the lower penholder. A tail end of the clip is raised and a pressing raised strips for a mobile phone is provided thereon.

A clip comprised of removably attached components. The clip may be attached to a writing instrument, such as a pencil, or stylus. The surface of the clip has male elements that allow the components to snap on to the clip so that the clip may be adorned. The components are secured to the clip so that they may rotate freely around the male element. The components may be comprised of decorative elements, such as jewels, initials, logos, or pictures. The components may be comprised of a utilitarian element, such as a lanyard, or a flashing light to indicate an incoming email. The components may have a tactile surface comprised of bumps, or waves. The components may comprise of movable elements such as a rolling ball, or star that spins. The tactile surface and moving elements of a component may aid in the treatment of anxiety and attention deficit disorders.

A writing device with input unit includes a case and an input unit receiving in the case. The input unit includes a flexible main body, a sensing electrode layer and a protection layer. The flexible main body has a first face and a second face. The sensing electrode layer has a first sensing electrode and a second sensing electrode disposed on the second face of the flexible main body. The protection layer is correspondingly disposed on the second face of the flexible main body to cover the sensing electrode layer. The writing device with input unit has small volume and is lightweight so that a user can conveniently carry, store and use the writing device with input unit.

The present subject matter pertains to a device that allows two different items of daily use to be connected together as a single article for the day to day convenience of the user. The subject matter employs connecting element which has dual engaging means to secure two articles at a time. It is used as an engaging means and also as a closing means for respective articles. The connecting element has different geometric features at its either ends so that it is used as an engaging means and a closing means for the articles with different geometric features.
