Clutching Is Not (Necessarily) the Enemy

open access: yesProceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems, 2015
Clutching is usually assumed to be triggered by a lack of physical space and detrimental to pointing performance. We conduct a controlled experiment using a laptop trackpad where the effect of clutching on pointing performance is dissociated from the effects of control-to-display transfer functions. Participants performed a series of target acquisition

Motor-driven rack-positioning device [PDF]

open access: yes, 1975
Ramped clutch plate prevents damage to gear traing and provides ample linear motion for actuation of microswitch. Operation of device is not affected by number of revolutions which pinion shaft must make to produce required translations.

Evolution of sociality in Anelosimus Spiders [PDF]

open access: yes, 2019
Most spiders are solitary and aggressive towards cohorts, but some have been found to live in groups and forage communally, even sharing in brood care. The benefits of group living outweigh the costs of inbreeding for these spiders, but how sociality has

SEASONAL INCIDENCE OF CAPTURE AND REPRODUCTION OF FIVE FOSSORIAL SNAKE SPECIES IN WEST VIRGINIA [PDF]

open access: yes, 2017
Museum specimens of five species of fossorial snakes collected in West Virginia during 1930–2000 were examined to determine monthly incidence of capture, adult body sizes, reproductive cycle, and clutch characteristics.

Adhesion-clutch between DCC and netrin-1 mediates netrin-1–induced axonal haptotaxis

open access: yesFrontiers in Molecular Neuroscience
The growth cone, a motile structure located at the tip of growing axons, senses extracellular guidance cues and translates them into directional forces that drive axon outgrowth and guidance.

Development of High Efficiency Dog Clutch with One-Way Mechanism for Stepped Automatic Transmissions

open access: yesInternational Journal of Automotive Engineering, 2019
In order to reduce drag losses and a clutch actuator load, the new dog clutch system for stepped automatic transmission is developed. Transmitting torque is converted to the engaging force because rotating shaft and dog clutch are connected with the ...
