Design and evaluation of an automatic gear-shifting system for manual wheelchairs
Just like shifting gears on a bicycle, multiple gears on a manual wheelchair can make it easier to complete many tasks of daily living. We developed an automatic gear-shifting system (AGS) for manually propelled wheelchairs. The AGS has three speeds – first gear: for ascending slopes or traversing …

Design and effects on handrim kinetics of an automatic gear-shifting wheel for manual wheelchairs
… as a result of these conditions. However, geared wheelchairs have been shown to decrease shoulder pain in MWCUs. Therefore, prototypes of 5-speed automatic gear shifting (AGS) wheels for wheelchairs have been developed. The automatic transmission on the AGS system senses the translational …

Fast and strong lightweight robots based on variable gear ratio actuators and control algorithms leveraging the natural dynamics
… particularly for mobile robots. Multiple gear ratios, like in a powertrain, address this issue by allowing an effective use of power over a wide range of output speeds, by enabling significant changes to the reflected intrinsic actuator impedances and by making possible the leveraging or …

Mechanical design of an automated vehicle driving system for drive cycle testing
… vehicle which is Perodua Myvi with automatic gear shifting. There are several findings that related to vehicle control which eliminate human as the handler. From the finding and the requirement to work on a small space area, the new concept for mechanical design is needed. The flow for design …

Fuel minimization of a moving vehicle in suburban traffic
… into account the effects of acceleration and gear shifting. Also, we use an existing model for the fuel consumption which depends quadratically on the speed of the vehicle. For simple cases (one traffic light), we derive analytical results using basic optimization theory and the …

Digital communication receiver algorithms and architectures for reduced complexity and high throughput
… improved via two methods: (1) data reusing and gear-shifting LMS and (2) reducing the length of the equalizer by capturing the sparse structure of underwater acoustic channels. In addition, the sparse structure resulting from the underwater channel can be exploited to reduce the complexity of …

Effectiveness of Compensatory Vehicle Control Techniques Exhibited by Drivers after Arthroscopic Rotator Cuff Surgery
… and, in particular, difficulty with the gear shifting control. Additionally, when considering the performance of non-primary vehicle tasks as assessed through a prescribed visor manipulation, sling use was not a significant factor for the task duration or completion of the task in a fluid …
