In this paper, a new measure method was suggested to examine the reaction time of visual attention of drivers using a new-style mechatronic visual attention measurement system. The system can control the peripheral environment illuminance and the present of stimulus at the start locations, and change the color of stimulus in terms of visual attention shift theory in three-dimensional (3D) space. The measurement system included the setting of observation location, stimuli location, moving speed, environment illuminance. The paper introduced the test method of visual function and the test procedures of the reaction time. The results demonstrated that this measurement system can be used to examine the reaction time and judgment response of drivers in three environmental illuminance conditions, and show that the response training for visual attention can improve the vision judgment ability of drivers.

This paper presents an integrated magnetic PDMS micropump for implantable drug delivery application. The micropump mainly consists of two structural PDMS layers: a PDMS functional layer that incorporates microchannels, a pump chamber and two planar check valves into a single layer, allowing for simple design and easy system integration, and the other PDMS membrane layer covering the pump chamber and holding a thin electroplated permalloy piece on top for magnetic actuation. The micropump can be driven by the interaction between the ferromagnetic permalloy and an external electromagnet, providing a remote and wireless operation method. Test results demonstrate that this micropump is able to produce a maximal flow rate of 0.15 μL/min at the driving frequency of 2 Hz with a volume resolution of approximately 1 nL per stroke, promising its application in various implantable biomedical systems.

This paper introduces the designs on visual attention measurement system based on the visual attention theory. The measurement system simulated the traffic environment and driving conditions, to examine the reaction time and accuracy of judge response of drivers. It applies to research the top-down and bottom-up controls of visual attention in three-dimensional (3D) space. It included the setting of observation location, stimuli location, moving speed, environmental illuminance and the design of software control interface. The paper describe how the stimuli can be presented by the control system and introduce the design of variable periphery environmental illuminance and obversion targets for detect tasks in detail. The results are demonstrated that this measurement system can be used to examine the reaction time and accuracy of judgment response in three environmental illuminance conditions.
