Abstract: A keyboard finger guide device includes an elongated divider this is positionable horizontally between two rows of a keyboard, and a plurality of curvilinear guides that are secured to the divider perpendicularly and are positionable vertically between a plurality of individual keys of the keyboard. The guides extend above the top surface of the keyboard keys to provide a constant guide for the first two fingers of a user's left and right hands in the typing position at rest. A keyboard with an integrated finger guide is also provided. The keyboard including a plurality of keys having protrusions along a top surface to act as a guide for receiving and aligning a users fingers according to a 10-finger typing method.

Abstract: A keyboard finger guide device includes an elongated divider this is positionable horizontally between two rows of a keyboard, and a plurality of curvilinear guides that are secured to the divider perpendicularly and are positionable vertically between a plurality of individual keys of the keyboard. The guides are constructed from a malleable and resilient material and can extend above the top surface of the keyboard keys to provide a constant guide for the first two fingers of a user's left and right hands in the typing position at rest. The guides can also extend level with the top surface of the keyboard keys at rest to selectively guide the first two fingers of a user's left and right hands while typing.

Abstract: A keyboard finger guide includes two or more elongated planar guides that are in a parallel orientation to each other. A plurality of curvilinear dividers is secured to the guides in a perpendicular orientation and provide a tactile guide to align fingers on a keyboard. The upper surface of the dividers can include a nonabrasive and malleable material, or the dividers can be completely constructed from a malleable material so as to allow the shape of the device to conform to variances in keyboard manufacture and designs.

Abstract: Recent invention of longitudinally chirped volume Bragg gratings has dramatically changed a design of high power femtosecond lasers. Replacing of bulky pairs of conventional surface gratings with compact and robust chirped volume Bragg gratings for stretching and compression of laser pulses in chirped-pulse-amplification systems enabled decrease of size and weight of those systems by several times. The methods and devices enable substantial increase of stretching time and compression to shorter pulses, enhancement of stretched and compressed beams quality by stationary or dynamic shaping of gratings, and shaping of laser pulses in both temporal and spectral domains.
