Tactile pin actuator
First Claim
1. A system comprising:
- a tactile pin;
a shaft movably coupled to the tactile pin;
a projection secured relative to the shaft, the projection adapted to rotate with the shaft;
a first surface; and
a second surface,wherein rotation of the shaft in a first rotational direction relative to the tactile pin causes the projection to rotate in the first rotational direction and the tactile pin to move linearly in a first linear direction away from the shaft, rotation of the shaft in the first rotational direction limited by the projection coming into contact with the first surface, andwherein rotation of the shaft in a second rotational direction relative to the tactile pin causes the projection to rotate in the second rotational direction and the tactile pin to move linearly in a second linear direction toward the shaft, rotation of the shaft in the second rotational direction limited by the projection coming into contact with the second surface.

Abstract
A tactile pin actuator comprises a tactile pin assembly that includes a tactile pin and a recess that has a first screw thread formed thereon. A stop assembly is rigidly coupled relative to the tactile pin actuator. A lead screw attached to a shaft is positioned in the recess and is mechanically engaged with the first screw thread. A projection extends axially from the shaft. Rotation of the shaft in a first rotational direction relative to the tactile pin assembly causes the tactile pin assembly to move linearly in a first linear direction away from the shaft. Rotation of the shaft in the first rotational direction ceases when the projection comes into contact with the stop assembly. Rotation of the shaft in a second rotational direction causes the tactile pin assembly to move linearly in a second direction toward the shaft. Rotation of the shaft in the second direction ceases when the projection comes into contact with the stop assembly.

14. A tactile pin module, comprising:
-
an external surface having a plurality of apertures formed therein; and a plurality of tactile pin systems, each tactile pin system corresponding to at least one of the plurality of apertures, and each tactile pin system comprising; a tactile pin; a recess having a first screw thread formed thereon, the recess rigidly coupled relative to the tactile pin; a shaft coupled with a second screw thread, the second screw thread mechanically engaged with the first screw thread; a projection extending from the shaft and secured relative to the shaft; a first surface; and a second surface, wherein rotation of the shaft in a first rotational direction relative to the tactile pin causes the tactile pin to move linearly in a first linear direction away from the shaft, rotation of the shaft in the first rotational direction limited by the projection coming into contact with the first surface, and wherein rotation of the shaft in a second rotational direction relative to the tactile pin causes the tactile pin to move linearly in a second linear direction toward the shaft, rotation of the shaft in the second rotational direction limited by the projection coming into contact with the second surface. - View Dependent Claims (15, 16, 17, 18, 19)

20. A braille display, comprising
a body; -
a retainer mechanically coupled to the body, the retainer adapted to form a frictional fit with an electronic computing device; a first recess formed in the body, the first recess adapted to receive a plurality of tactile pin modules; and a plurality of tactile pin modules positioned in the first recess, each tactile pin module, comprising; a tactile pin; a shaft movably coupled to the tactile pin; a projection secured relative to the shaft, the projection adapted to rotate with the shaft; a first surface; and a second surface, wherein rotation of the shaft in a first rotational direction relative to the tactile pin causes the projection to rotate in the first rotational direction and the tactile pin to move linearly in a first linear direction away from the shaft, rotation of the shaft in the first rotational direction limited by the projection coming into contact with the first surface, and wherein rotation of the shaft in a second rotational direction relative to the tactile pin causes the projection to rotate in the second rotational direction and the tactile pin to move linearly in a second linear direction toward the shaft, rotation of the shaft in the second rotational direction limited by the projection coming into contact with the second surface.
