Digital Sun Sensor Multi-Spot Operation
The operation and test of a multi-spot digital sun sensor for precise sun-line determination is described. The image forming system consists of an opaque mask with multiple pinhole apertures producing multiple, simultaneous, spot-like images of the sun on the focal plane. The sun-line precision can be improved by averaging multiple simultaneous measures. Nevertheless, the sensor operation on a ...
متن کاملSpot Sizes on Sun-like Stars
The total area coverage by starspots is of interest for a variety of reasons, but direct techniques only provide estimates of this important quantity. Sunspot areas exhibit a lognormal size distribution irrespective of the phase of the activity cycle, implying that most sunspots are small. Here we explore the consequences if starspot areas were similarly distributed. The solar data allow for an...
متن کاملAn interesting case of aluminum phosphide poisoning
Ingestion and inhalation of phosphine are 2 forms of toxicity and their clinical manifestation is extremely wide. A 22-year-old girl was admitted with complaints of nausea, vomiting and epigastric pain after eating lunch. She had a history of celiac disease. On arrival, she was alert and hemody...
متن کاملSun SPOT Orchestra: Algorithmic Composition for Wireless Sensor Networks
A system for algorithmically composing music for wireless sensor networks (WSN) is proposed. The hardware and software requirements are outlined for the individual WSN motes and the network as a whole. Justification for the project proposal, background information on WSN and algorithmic composition, and overall project vision are presented. Finally, we concl...
متن کاملInferno in Embedded Space: Porting to the Sun SPOT
We report, here, on a project to port the Inferno operating system to the Sun SPOT sensor platform. The port provides support for the temperature and light sensors, the threeaxis accelerameter, LEDs, momentary contact switches, and GPIO pins. Communication among sensors is provided by an IPv6 implementation running over the integrated 802.15.4 radios.
