Apparatus and method for the treatment of computer vision syndrome using a computer including a screen, a processor, memory and an I/O device. A set of instructions for the computer that includes programs for conducting hand-eye exercises in preselected sequences are loaded into the computer and run. Alternately, a pair of hand wands having a handle at one end and an LED light positioned on the other end are held by a user in front of the computer and a plurality of slap switches having means for detachably attaching the slap switches to a surface are positioned relative to the user and the computer. The user through the use of the slap switches and the hand wands carry out sequences of exercises that will rehabilitate the user regarding computer vision syndrome. The results of the exercises are communicated wirelessly from the hand wands and the slap switches to the computer.

A laser energy microinscribing system, comprising a semiconductor excited Q-switched solid state laser energy source; a cut gemstone mounting system, allowing optical access to a mounted workpiece; an optical system for focusing laser energy from the laser energy source onto a cut gemstone; a displaceable stage for moving said gemstone mounting system with respect to said optical system so that said focused laser energy is presented to desired positions on said gemstone, having a control input; an imaging system for viewing the gemstone from a plurality of vantage points; and a rigid frame supporting said laser, said optical system and said stage in fixed relation, to resist differential movements of said laser, said optical system and said stage and increase immunity to vibrational misalignments. The laser energy source is preferably a semiconductor diode excited Q-switched Nd:YLF laser with a harmonic converter having an output of about 530 nm. The system may further comprise an input for receiving marking instructions; a processor for controlling said displaceable stage based on said marking instructions and said imaging system, to selectively generate a marking based on said instructions and a predetermined program; and a storage system for electronically storing information relating to images of a plurality of workpieces.

Methods and systems are presented for determining position and velocity information using angles-only measurements for a moving observer in a three-dimensional space, in which three or more observations are obtained by the observer of objects with known positions, line of position vectors are generated which correspond to the individual observations, and position and velocity vectors for a chosen time are determined using a closed-form least-squares minimization over the Euclidian distances between each line of position vector and the observer's estimated position at the time of the observation.

A diamond anvil of the type comprising (a) a pair of diamonds having a facing, plane parallel bearing surfaces and (b) a device for applying a force to the diamonds tending to press the bearing surfaces together. Both diamonds have a peripheral surface, extending outward from the bearing surface, which is tangent to the bearing surface at the interface thereto and which tapers away from the bearing surface with a continuous curved surface.
