Abstract: A health care information provider system may provide information about health care objects managed by a health care provider. A name generating system may generate an object name for each of the health care objects which may include provider information indicative of the identity of the health care provider which manages the health care object, and object information indicative of the identity of the health care object. The object information may be devoid of any personal health information, even in a form which can be decrypted by a decryption key. A computer system appliance may protect the privacy of medical record information stored in a computer information storage system and may include a medical record distribution compartment, a medical record acquisition compartment, and a security compartment. The medical record distribution compartment and the medical record acquisition compartment may be configured to communicate with one another only thought the security compartment.

Abstract: Charge transfer is provided to or from an electrically isolated test body by AC modulation of the photoelectric effect. More specifically, a reference body is disposed near the test body without physical contact between the reference and test bodies. Facing surfaces of the reference and test bodies are illuminated by optical radiation having a sufficiently short wavelength that charged particles are emitted from the reference and test bodies. An electrical bias is established between the reference body and the test body. Both the optical radiation and the electrical bias are modulated at the same frequency. A magnitude and direction of a charge transfer rate between the reference and test bodies is set by selecting a phase relation between the optical radiation and the electrical bias.

Abstract: An angular magnification effect of diffraction is exploited to provide improved sensing and scanning. This effect is most pronounced for a normal or near-normal incidence angle in combination with a grazing diffraction angle, so such configurations are preferred. Angular sensitivity can be further enhanced because the width of the diffracted beam can be substantially less than the width of the incident beam. Normal incidence configurations with two symmetric diffracted beams are preferred, since rotation and vertical displacement can be readily distinguished. Increased sensitivity to vertical displacement can be provided by incorporating an interferometer into the measurement system. Quad cell detectors can be employed to provide sensitivity to rotation about the grating surface normal. A 2-D grating can be employed to provide sensitivity to angular displacements in two different planes (e.g., pitch and yaw).
