A novel blending stump pencil device that provides a user with one implement for both drawing and blending. The device comprises a wood-bodied pencil with a blending stump attached to a rear of the pencil via a securing apparatus. The device comprises a clear finish and a removable plastic sleeve that protects the blending stump from damage and debris. Further, the device can be included in a kit with multiple pencil types.

A computer-implemented method for audio to tactile enhancement comprising obtaining audio data comprising a sample of speech, generating at least one haptic cue definition by performing a first signal processing operation on at least one portion of the audio data, and actuating a haptic actuator comprised in a user device or a writing instrument according to the at least one haptic cue definition. Examples concern obtaining a pulse signal representing a pulse of a user of the user device or the writing instrument, wherein the pulse signal is obtained substantially simultaneously with obtaining the audio data and applying a second signal processing operation to the pulse signal, wherein the second signal processing operation calculates a heart rate variability signal of the user.

The present invention teaches that a custom designed tool might serve as a marker cap for a standard size and diameter of marker such as a Sharpie® or Revmark® brand marker, along with an LED or low light LED or dim red LED or even infrared LED, and a hex drive socket which could then be used with an appropriate size of hex bit (such as a BITHEX™ tool head) for the exact size of adjustment screw heads found on any particular laser gun aiming device. The LED serves to light the laser aiming device screw head and the hex bit tool head, and in embodiments may be quite dim or otherwise inconspicuous.

A housing element for a writing instrument includes a hollow, sleeve-shaped, elongated base body having an opening for receiving the writing instrument or a pencil lead of the writing instrument at a first longitudinal end. The base body has a second longitudinal end, which is opposite the first longitudinal end, and has a retaining recess that is formed with a polygonal cross section for directly or indirectly retaining a bit in a rotationally fixed manner. A writing instrument including the housing element is also provided.

A collapsible dual screwdriver assembly pliers or drive-pliers for short, comprises a pliers and two screwdriver assemblies, where the screwdriver assemblies are individually removably attachable in a stowed position and an extended position. In the stowed position each screwdriver assembly can provide compact storage of the tool as well as function as a portion of a handle for the other screwdriver assembly. In the extended position each screwdriver assembly can be used as an extended handle for the pliers, as well as, function as a multi-bit screwdriver individually.
