A measurement device and method that allows for precise placement, as well as more accurate measurement of various body parts, including vessels, lesions, and/or lumens of vessels of various body parts. The measurement device comprises one or more measurement tapes having (i) a plurality of measurement marks for measuring a distance and/or a length of a vessel and (ii) a plurality of circular indicators for measuring a diameter of a lumen of the vessel.

A ruler, steel square, combination square, try square, or the like has a surface partially or entirely covered with a polymeric film. The polymeric film has a writing surface upon which legible and erasable markings may be made with a standard graphite- or wax-based pencil.

An inspection apparatus configured to selectively couple to a receiver mount of a survey inspection assembly is disclosed. The inspection apparatus comprises an elongated body extending along a longitudinal axis from a proximal inspection portion to a distal inspection portion. The apparatus further comprises an inspection feature configured to slidably engage the longitudinal axis. The inspection feature is configured to extend a visual reference of at least one measurement reference disposed on the inspection apparatus.

Current techniques for measuring chemical expansion in thin film structures are too slow, too imprecise, or require synchrotrons. In contrast, nanoscale electrochemomechanical spectroscopy (NECS) can be used to make nanoscale measurements at time scales of seconds with simple contact or non-contact sensors. In a NECS measurement, a sample, such as thin-film oxide structure, is subjected to a temporally modulated stimulus, such as a sinusoidally alternating voltage. The stimulus causes the sample to expand, contract, deflect, or otherwise deform. A sensor, such as a contact probe or optical sensor, produces an electrical signal in response to this deformation that is correlated with the temporal modulation of the stimulus. Because the stimulus and deformation are correlated, the temporal modulation of the stimulus can be used to filter the deformation signal produced by the sensor, producing a precise, sensitive measurement of the deformation.

A measuring device having a flange extending from a rule portion at one end and an ergonomic module on the other end. The ergonomic module has side surfaces which angle at the same angle as side edges of the flange to permit the measuring device to be supported on the side surfaces during use. A magnet may be encapsulated in the ergonomic module for supporting the measuring device when not in use. A thumb depression is formed in the ergonomic module to facilitate use by the user

An apparatus comprises a pin, a stop, a spring, one or more flanges, a measurement device, and a transmitter. The pin comprises a first end configured for insertion in an aperture in a component. The stop is slidably engaged with the pin and configured to contact a first surface of the component as the pin is inserted into the aperture in the component. The spring couples the stop to the housing. The one or more flanges are located proximate to the first end of the pin. The one or more flanges are configured to contact a second surface of the component. The measurement device is coupled to the pin. The transmitter is communicatively coupled to the measurement device.
