Provided is an electronic pen that includes a body portion housing of an electronic pen body portion has housed therein a refill body and a circuit board having a side switch formed by a push button switch mounted thereon, and has a pen-point opening portion through which a pen point of the refill body protrudes. A pressing member is provided in a side opening portion of the body portion housing such that the pressing member is disposed on the side switch in such a manner as to be prevented by an engagement portion from protruding outwardly from a side surface of the body portion housing. The side switch of the circuit board is operated through the pressing member of the electronic pen body portion when an operation unit of the outer housing having the electronic pen body portion installed therein is pressed.

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

Carpenter pencil caliper is a two-piece device that attaches to a carpenter's pencil with a scale, ruler imprint, or rule imprint on the carpenter's pencil wherein this three-piece assembly is then used as a caliper to measure the length, width, and/or height of a workpiece. This three-piece assembly may also be used to mark or scribe a line in a workpiece at a specific, precise, or measured location and/or mark or scribe a specifically sized or measured circle in a workpiece at a specific, precise, or measured location. The two-piece device is a specially designed and shaped to reversibly attach to a standard sized carpenter's pencil in order to perform the marking and/or scribing of the workpiece. A workpiece is a piece of building material such as wood, composite, or metal that is used to build a structure or a device.

A translator pen and a translation method using same are provided. The translator pen includes a housing and a pen head. The housing forms a first accommodation cavity adapted to accommodate an image collector. An outer contour of the pen head is formed into a tapered shape, an outer diameter of the pen head gradually decreases along a direction of the pen head away from the housing and forms a second accommodation cavity adapted to accommodate a pen core. At least a portion of the end of the housing, which does not form the pen head, forms an inclined surface. The inclined surface is inclined relative to the outer contour of the pen head toward an outside of the housing along a direction of the housing away from the pen head. The image collector is configured to face the inclined surface.

A writing system that includes a reusable notebook including a sheet having a working surface. The working surface includes a printed code and an operative control. The writing system includes a writing instrument configured to capture images of the printed code and a computing device configured to communicate with the reusable notebook and/or the writing instrument. The sheet includes a surface coating over the working surface configured so that a writing material of the writing instrument can be removed by applying a dry ancillary device.
