An Event-Based Neurobiological Recognition System with Orientation Detector for Objects in Multiple Orientations.

A new multiple orientation event-based neurobiological recognition system is proposed by integrating recognition and tracking function in this paper, which is used for asynchronous address-event representation (AER) image sensors. The characteristic of this system has been enriched to recognize the objects in multiple orientations with only training samples moving in a single orientation. The system extracts multi-scale and multi-orientation line features inspired by models of the primate visual cortex.

A 12-bit high-speed column-parallel two-step single-slope analog-to-digital converter (ADC) for CMOS image sensors.

A 12-bit high-speed column-parallel two-step single-slope (SS) analog-to-digital converter (ADC) for CMOS image sensors is proposed. The proposed ADC employs a single ramp voltage and multiple reference voltages, and the conversion is divided into coarse phase and fine phase to improve the conversion rate. An error calibration scheme is proposed to correct errors caused by offsets among the reference voltages.

[On-chip magnetic separation of microcantilever immunosensor based on the CdSe QDs-tagged magnetic microbead].

We designed a novel microcantilever immuosensor based on magnetic microbead, applying different-sized CdSe QDs as fluorescent probes and polystyrene magnetic microbead. The novel microcantilever immuosensor used fluorescent probes embedded polystyrene microbeads and specific antibodies on the surface of the polystyrene microbead. In addition, we studied the mechanism of the on-chip magnetic separation, the structure of micro-electromagnet and the microbead magnetization by the micro-magnetic field, the snake-shaped planar micro-electromagnet for the novel microcantilever immuosensor.

[Human-centered ergonomical study and applications in manned spacecraft project of China].

High G and weightlessness are two important environment factors that are unavoidable during spaceflight. They will bring key effects on astronauts' posture and working efficiency. In this paper, on the basis of experience of China first manned spacecraft project in the past 10 years, the concept of space ergonomics and its role in the project were reviewed.
