Abstract: A scanning probe microscope and method of operation for monitoring and assessing proper tracking between the tip and sample, as well as automating at least some aspects of AFM setup previously done manually. Preferably, local slopes corresponding to the acquired data are compared to determine a tracking metric that is self-normalizing.

Abstract: A bracket and nut assembly includes a first bracket, a second bracket and a captured nut. The first bracket includes a body with first end having with an aperture extending therethrough. The second bracket includes a first end with an elongated aperture and a second end moveably attached to the body portion of the first bracket. A captured nut is retained within the elongated aperture. The nut includes a first piece coupled to a second piece and is axially translatable and rotatable within the elongated aperture.

Abstract: An oil deflector assembly includes an oil deflector plate for attachment between a crankshaft and an oil pan. The oil deflector plate assembly further includes a plurality of nuts and washers rotatably captured and retained by the plate for attaching the plate with respect to an engine block. The captured nuts and washers are preassembled to the plate, thereby improving engine assembly efficiency. In a preferred embodiment, the threaded hole of each nut is tapered to improve alignment with a corresponding threaded stud, and the washer includes a tapered hole to facilitate washer deformation thereby to lock the washer against the plate.

Abstract: A method for electronically reserving a parking space at a parking facility through a computer network comprises the step of accessing by a user communication with a server computer on the computer network, the server computer operating a program for reserving a parking space at a parking facility and containing data relating to a plurality of parking facilities. Thereafter, the user identifies a parking facility and the time for which a parking space is required in the parking facility, and reserves the parking space in the parking facility. Payment is effected for the parking space by providing information to enable the server computer to directly or indirectly transfer funds for the parking reservation from a user designated payment source to target account. Then, confirmation from the server computer is received that the parking reservation has been made.
