Abstract: Wind turbine blade comprising a lightning protection system, said lightning protection system comprising a first lightning receptor mounted near the tip of the blade and an electrical conductor electrically connecting the first lightning receptor and the base of the wind turbine blade. The lightning protection system further comprises a first aerodynamic fence attached to the wind turbine blade between the lightning receptor and the tip of the blade. In this way, a zone of smoother airflow is provided which makes a more effective target for lightning to strike, thereby avoiding damage to other parts of the blade.

Abstract: Methods, systems, and apparatuses for predicting a user field-of-view change and determining transmission regions of immersive video (IV) content for an IV device are presented. A field-of-view change of a user device may be predicted. A transmission region in one or more video frames of the IV content may be determined based on the predicted change.

Abstract: A wearable body harness has first and second shoulder straps arranged in an X-shape, a back plate on a rear portion of the shoulder straps with the first shoulder strap crossing over the second at the back plate. The back plate includes a pair of lower guide slots, having a first lower guide slot side and a second lower guide slot side contiguous with the first and arranged at an angle relative thereto, and a pair of upper guide slots, having a first upper guide slot side and a second upper guide slot side contiguous with the first and arranged at an angle relative thereto. A first of the pair of upper and lower guide slots route a webbing material of the first shoulder strap. A second of the pair of upper and the pair of lower guide slots route the webbing material of the second shoulder strap.

Abstract: Motion detection computing devices may have difficulty determining precise motions of a user who suffers from unintended movement, such as tremors, associated with a physical or medical condition. Aspects described herein relate to motion compensation for detected motion input, e.g., 3D motion, from such users. As described herein, a system may detect the presence of rhythmic motion and/or other input characteristics within captured motion input from a user. The system may determine one or more filters to apply to the captured motion input based on the rhythmic motion, other input characteristics, and/or information in a user profile. The one or more filters may be applied to the captured motion input in order to suppress or minimize the effects of the rhythmic motion and/or other input characteristics thereby resulting in an enhanced user experience in an interactive system, such as a 3D, virtual and/or augmented reality environment.

Abstract: Systems, methods, and mechanisms for sound beam focal point determination within an acoustic medium may include propagating a first sound beam to intersect a second sound beam, where the second sound beam converges at a focal point. Signals representative of sound pressure in the acoustic medium may be received from one or more sensors. A direction and/or focal length of the first sound beam within the acoustic medium may be adjusted, based, at least in part, on the received signals, to produce a maximum amplitude of signals generated from nonlinear mixing of the first sound beam and the second sound beam, where the maximum amplitude may correspond to the intersection of the first sound beam with the focal point of the second sound beam. A location of the intersection may be determined, at least in some instances, using a time-of-arrival analysis on the received signals.

Abstract: Systems, methods, and mechanisms for sound beam focal point determination within an acoustic medium may include propagating a first sound beam to intersect a second sound beam, where the second sound beam converges at a focal point. The first and second sound beams may originate from known locations. A direction of the first sound beam within the acoustic medium may be adjusted to produce a maximum amplitude of signals generated from nonlinear mixing of the first sound beam and the second sound beam, where the maximum amplitude may correspond to the intersection of the first sound beam with the focal point of the second sound beam. A location of the intersection may be determined, at least in some instances, based on the known locations, the adjusted direction of the first sound beam, and a direction of the second sound beam.

Abstract: A wearable body harness may include a first shoulder strap; a second shoulder strap; at least one adjustment mechanism having a first end connected to at least one of the first shoulder strap and the second shoulder strap and a free, second end opposite the first end; a belt strap connected to the first shoulder strap and the second shoulder strap via the at least one adjustment strap; and an adjustment mechanism configured for selectively raising or lowering a position of the belt strap relative to the first shoulder strap and the second shoulder strap. The adjustment mechanism may be connected to at least one of the first shoulder strap and the second shoulder strap. The second end of the at least one adjustment strap is connected to the adjustment mechanism.

Abstract: The invention introduces a new RF test and measurement methodology based on optical signal processing that has the capability to measure all of the RF parameters (both amplitude and phase) of an electronic component or system including transmission (S21) and reflection (S11). It can also be applied to measuring the electro-optic properties of electro-optic modulators, both phase modulators and intensity modulators. The basis of the invention is to use the RF information encoded in the optical sidebands generated by an electro-optic modulator to determine all of the relevant parameters of an electronic or electro-optic device. Optical carrier suppression techniques are used to isolate the information carrying optical sidebands from the dominant optical carrier.
