Abstract: A combination lock includes various features that make the lock manipulation-resistant. The lock has a rocker arm with a curved underside section that contacts a roller on a cam that rotates when the lock dial is rotated. The smooth curve and an angled contact portion on the rocker arm causes the force applied to the rocker arm by the roller to be gradual rather than abrupt, ensuring that the contact point between the rocker arm and the roller is unpredictable. The lock may also include various spring-biased relocking devices that are biased away from the travel path of the bolt when the back cover is attached to the housing. The biasing force in the relocking device causes the device to move into the travel path of the bolt when the back cover is displaced or removed, preventing the bolt from moving to an unlocked position.

Abstract: Evanescent wave scattering by a scanning probe in a scanning probe microscope is utilized to determine and monitor separation between a scanning probe and a sample. A laser light is totally internally reflected at the interface between a more optically dense (incident) medium and less optically dense (transmitting) medium, exciting a decaying evanescent field in the less optically dense medium. A scanning probe, such as a colloidal probe, is dipped into the evanescent field, which scatters off the scanning probe. The portion of the scattered field propagates back into the incident medium and is then detected by a detector. A dependency between the intensity of the scattered evanescent field and the separation between the probe and the incident medium was measured and used in determining the separation. This dependency of intensity is used to prepare images or maps of interfaces. A particular application of determining the separation between the probe and the sample in an atomic force microscope is disclosed.

Temperature sensors are provided within the first and second cavities, respectively, to measure the gas temperatures within the cavities.
