摘要:
An optical device for measuring and inspecting a physical and optical characteristic of an object. In the preferred embodiment, the optical device comprises a light source emitting a beam of light rays along an optical axis, a light-sensitive electronic device, preferably a charge-coupled device, positioned along the optical axis converting an image formed from the beam of light rays being reflected from the object into an electrical signal. An image rotating device, preferably a Dove prism, is positioned along the optical axis between the object and the light-sensitive electronic device. A rotating device rotates the image rotating device at an angle of rotation. The rotating device, preferably a d-c step motor, converts the angle of rotation of the image rotating device into an electrical signal. The angle of rotation of the image rotating device is based on a step position of the d-c step motor. The optical device determines physical and optical characteristics of the object based on the strength of the electrical signal from the light-sensitive electronic device and the electrical signal from the d-c step motor.

Photochemical tissue boding methods for bonding neural tissues include the application of a photosensitizer to a tissue and/or tissue graft, followed by irradiation with electromagnetic energy to produce a tissue seal. The methods are useful for tissue adhesion, such as in wound closure, tissue grafting, skin grafting, musculoskeletal tissue repair, ligament or tendon repair, neural repair, blood vessel repair and corneal repair.

Photochemical tissue bonding methods include the application of a photosensitizer to a tissue, e.g., cornea, followed by irradiation with electromagnetic energy to produce a tissue seal. The methods are useful for wound repair, or other tissue repair.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transferring ownership privileges. In one aspect, a method includes identifying an ownership privilege in a system that permits users to acquire a write lock on one or more resources in a plurality of resources. The ownership privilege for a first plurality of users located in a first geographic region is revoked based at least partly on a determination that a current time of day in a different, second geographic region satisfies a criteria. The ownership privilege is granted to a different second plurality of users located in the second geographic location responsive to the determination.
