摘要： An apparatus to indicate unauthorized manipulation of at least one protected device enclosed in a housing is provided. The apparatus includes a structure attached to a first portion of the housing and a token switch attached to a second portion of the housing. The token switch is operably positioned with reference to the structure. The token switch includes a plunger, and a register programmed with a value. The register is communicatively coupled with a processor in a circuit. The circuit is communicatively coupled to drive the device. The structure, the token switch, and the circuit are internal to the housing when the housing is in a closed position. The plunger and the structure are positioned to generate a current when the housing is opened. The programmed value in the register is changed by the generated current and the processor takes an action responsive to the change in the programmed value.

摘要： Current control biasing of a ring laser gyroscope is employed to protect electrode seals. A frame of a ring laser gyroscope has more than one electrode attached to it. An electric field is created between the electrodes during the operation of the gyroscope, which causes ions in the frame to migrate towards a lowest electrical potential. Electrode seals are located between the electrodes and the frame. By providing a positive power supply voltage and connecting the current control to the non-ground side of the power supply, the mounting structure may be at the lowest electrical potential. The ions will then migrate towards the mounting structure, which significantly reduces migration to the electrodes.

摘要： A method for determining a surface quality of a substrate sample using a differential interference contrast microscope is described. The microscope includes an eyepiece, an eyepiece focus adjustment, a microscope focus adjustment, a light source, at least one of an aperture or reticule, a camera view, a prism and an eyepiece. The method includes calibrating the focus of the eyepiece with the focus of the camera and determining a peak response ratio for the microscope through adjustment of phase between differential beams of the microscope. The substrate sample is placed under the microscope, illuminated with the light source, and brought into focus with the microscope focus. Phase between differential beams is adjusted, at least one image of the substrate sample is captured and processed to determine a level of surface structure on the substrate sample.

摘要： A ring laser gyro having a high temperature seal. The ring laser gyro includes a laser block of known construction having a closed loop passage formed within the block in the shape of a polygon. Mirrors positioned at the intersection of each side of the polygon-shaped closed loop passage create an optical closed loop path through passage. A lasing gas is sealed within the closed loop passage, and electrodes mounted to the block and in fluid communication with the passage create at least one laser that traverses the optical closed loop path in the passage. The electrodes are mounted on the laser block with a high temperature seal comprising a washer having a low coefficient of thermal expansion and an optical bond between the washer and the laser block In a preferred embodiment, the laser block and the washer are formed from the same material to ensure that these structures expand at substantially the same rate when the ring laser gyro is used in a high temperature application.
