Abstract: An engraving system operable to engrave user-loaded items is provided. The engraving system may have a housing, an engraver located within the housing, and a carrier configured to receive from a user a cartridge holding then item to be engraved and to position the cartridge relative to the engraver. The carrier may be configured to engrave the item via windows in the cartridge, and to flip the cartridge relative to the engraver for engraving on multiple sides of the item.

Abstract: The present application is directed to a laser scribing system for scribing photovoltaic substrates and includes a support body, one or more positioning devices positioned proximate to the support body and configured to engage and position one or more photovoltaic substrates relative to the support body, at least one grate system positioned proximate to the support body, the grate system formed from one or more grate members, the grate members defining one or more scribing passages in the grate system, and at least one scribe system positioned proximate to the support body, the scribe system having at least one scribe system body disposing one or more scribe devices, the scribe devices positioned proximate to the scribing passages and configured to scribe the substrate supported by the support body.

Abstract: A bi-directional slide mechanism. A pair of master and slave disks engages opposite sides of the platform. Rotational drivers are connected to master disks so the disks rotate eccentrically about their respective axes of rotation. Opposing slave disks are connected to master disks on opposite sides of the platform by a circuitous mechanical linkage, or are electronically synchronized together using stepper motors, to effect coordinated motion. The synchronized eccentric motion of the pairs of master/slave disks compels smooth linear motion of the platform forwards and backwards without backlash. The apparatus can be incorporated in a MEMS device.

Abstract: An apparatus for positioning an item that provides two-dimensional, independent orthogonal motion of a platform in a X-Y plane. A pair of master and slave disks engages opposite sides of the platform. Rotational drivers are connected to master disks so the disks rotate eccentrically about axes of rotation. Opposing slave disks are connected to master disks on opposite sides of the platform by a timing belt, or are electronically synchronized together using stepper motors, to effect coordinated motion. The coordinated eccentric motion of the pairs of master/slave disks compels smooth linear motion of the platform in the X-Y plane without backlash. The apparatus can be a planar mechanism implemented in a MEMS device.
