Abstract: Embodiments of a recombinant human Parainfluenza Virus (hPIV) F ectodomain trimer stabilized in a prefusion conformation are provided. Also disclosed are nucleic acids encoding the hPIV F ectodomain trimer and methods of producing the hPIV F ectodomain trimer. Methods for inducing an immune response in a subject are also disclosed. In some embodiments, the method can be a method for treating or inhibiting a hPIV infection in a subject by administering a effective amount of the recombinant hPIV F ectodomain trimer to the subject.

Abstract: Methods and apparatuses for athletic performance and technique monitoring are disclosed. In one example, a sensor output is received associated with a movement of a user torso during a running motion. The sensor output is analyzed to identify an undesirable torso motion.

Abstract: An apparatus for detecting a light scattering target includes a light source which illuminates a first area of an article with substantially collinear light and a second area surrounding the first area with substantially non-collinear light. An electronic vision system detects a position of a light scattering target within the second area to determine a compliance of said position with a desired position. The substantially collinear light is preferably directed upon the article in a direction substantially perpendicular to a plane along which the article is disposed. A shroud member is preferably disposed between the light source and the article, the shroud member having an aperture through which the light from the light source passes to reach the article, and through which at least a portion of the light is reflected back to the vision system. Preferably, the target is a laser textured index mark on a data storage disc.

Abstract: An apparatus and associated method for measuring vibration in an article having a rotating member. The device comprises a motion sensitive transducer attachable to the article comprising an output producing a time domain analog signal in response to the vibration. An analog-to-digital data acquisition member comprises an input connected to the transducer output for sampling the transducer signal and comprising an output producing a time domain digital signal from the sampling. A timing sensor is adapted to detect an instantaneous speed of the rotating member and triggers the data acquisition member to begin sampling when the rotating member is rotating. A processor comprises an input connected to the data acquisition member output for translating the time domain digital signal to a frequency domain digital signal and determining the magnitude and phase of the vibration signal at a frequency associated with the instantaneous speed of the rotating member.
