An analysis of forces and conditionswhich influence the successful passageof a carriage over an intermediate support jackduring downhill multi-span logging

In this paper, a catenary analysis of static skyline, mainline and haulback cable tensions just prior to an unsuccessful attempt by a carriage to pass an intermediate support jack is presented. Field tests were conducted for a range of skyline deflections and span chord slopes. Data collected during the field tests included static and dynamic cable tensions and cable geometry. The relationship between upper span skyline deflection, the percent change in span chord slopes, and their influence on successful carriage passage was determined. During the field tests it was observed that maintaining a taut haulback as the carriage passed the support jack prevented the carriage from surging out of control and reduced dynamic tension fluctuations. It was also observed that yarding the loaded carriage uphill over the support jack was prohibited by skyline deflections which still allowed successful carriage passage for the downhill yarding configuration

Sensors and actuators

This chapter addresses sensors and actuators for three main sensory modalities: hearing, vision, and touch. Technology in recent years was often focused on flat displays, e.g., or smartwatches. In contrast, the focus of this chapter is on wearable technologies of the post-smartphone area, allowing rich sensory input and output modalities. New approaches for tactile feedback include fiber-based sensors and actuators for e-textiles as well as complex 3D-fiber structures. Wearable sound sources and innovative sound-projection solutions using perceptual knowledge can replace complex distributed channel systems. One way to reduce latencies in vision are Organic Light-Emitting Diode (OLED) eyeables, that have the potential to significantly improving reaction time and power consumption. Combining the expertise of human perception and action with that on sensors and actuators contributes to augmented perception and interaction to exchange perceptual knowledge, which is needed for holistic sensor and actuator development. Moreover, sensors and actuators combined with tactile electronics in terms of flexible electronics and circuits for interfacing/processing explore new technologies for haptic and robotic systems
