Abstract: An orthotic foot brace for a person wearing a footwear includes: a lower leg holder; a lower leg strut extending downwardly towards the footwear; a foot strut having a rear section secured to the vertical strut, at least one of a median section and a lateral section located on a respective side of the footwear and extending outwardly thereof, and a front section securable to an instep section of the footwear; and a brace retaining member secured to the foot strut juxtaposed to the footwear, and extending from the median side of the footwear to the lateral side of the footwear, outwardly thereof, and restraining a rearwardly pivotal movement of the brace.

Abstract: An analytical model simulates the propagation of radiation through a coated continuous web where layer thickness and refractive index, as variables, determine the speed and direction of transmitted radiation. The model predicts characteristics of transmitted radiation based on characteristics of incident radiation and initially assigned values for layer thicknesses. Coating thickness(s) are ascertained in a process whereby incident radiation of known characteristics is directed onto a coated web and thereafter, actual measurements of transmitted radiation are compared to predicted characteristics. Using a fitting algorithm, the assigned thickness(es) of the layer(s) of the model are adjusted and the process repeated until the actual and predicted values are within desired limits at which time, the assigned thickness(es) represent the measured calipers.

Abstract: An apparatus for incorporation into time-domain spectroscopy systems that creates a continuous reference whereby a sample pulses' phase and amplitude can be tracked and corrected employs a beam splitter to generate sample and reference pulses. A detector is positioned for receiving the reference radiation pulses that do not interact with the sample. The same detector is also positioned for receiving the sample radiation pulses that emerge from the sample. The apparatus can be readily implemented by being configured between the emitter and detector of a terahertz time-domain spectrometer. The reference pulse is used to trace the changes in time and amplitude of the sample pulse. Since any changes in the reference pulse will most likely manifest in the sample pulse, the reference pulse is monitored and used to correct the sample pulse and thereby reduce the effects of jitter.

Abstract: A method for compensating for errors in a spectrometer is provided that includes measuring at least a portion of a path length for a signal traveling through the spectrometer during a measurement scan of a material. A detector signal corresponding to the measurement scan is generated. Compensation for errors in the detector signal is provided based on the measurement of the path length.
