A physiological information detection system includes an image-capturing unit, an image-processing unit and a data-transmitting unit. The image-capturing unit is provided to capture a series of images of head portions and connects with the image-capturing unit to receive the captured images. The image-processing unit is operated to process the captured images and to trace a head portion area and a neck portion area thereof in the processed images. The image-processing unit is further operated to process the captured images to retrieve temperature data from the selected head portion area and the selected neck portion area. The image-processing unit is further operated to convert variations of the temperature data into estimated pulse data. The data-transmitting unit connects with the image-processing unit to transmit the estimated pulse data to a predetermined device.

Social networks have been regarded as a timely and cost-effective source of spatio-temporal information for many fields of application. However, while some research groups have successfully developed topic detection methods from the text streams for a while, and even some popular microblogging services such as Twitter did provide information of top trending topics for selection, it is still unable to fully support users for picking up all of the real-time event topics with a comprehensive spatio-temporal viewpoint to satisfy their information needs. This paper aims to investigate how microblogging social networks (i.e. Twitter) can be used as a reliable information source of emerging events by extracting their spatio-temporal features from the messages to enhance event awareness. In this work, we applied a density-based online clustering method for mining microblogging text streams, in order to obtain temporal and geospatial features of real-world events. By analyzing the events detected by our system, the temporal and spatial impacts of the emerging events can be estimated, for achieving the goals of situational awareness and risk management. © 2012 Elsevier Ltd.

A bug zapper including a body, a fan and a light source is disclosed. The body has a compartment, an opening, a channel arranged between the compartment and the opening, and a coupling portion arranged between the compartment and the channel. The channel is formed by an enclosed reflection wall and gradually expands from the coupling portion towards the opening. The fan is coupled with the coupling portion. The light source is mounted on a location of the body adjacent to the fan and irradiates light in the channel. As such, the efficiency in attracting the mosquitoes is outstanding and the negative effect to the human is reduced.
