The Power of Salt

Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to mechanical engineers at MIT. They evaluated an emerging method of power generation called pressure retarded osmosis (PRO) in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less-salty stream would cross the membrane to a pre-pressurized saltier side, creating a flow that can be sent through a turbine to recover power.

Prepping Advanced Driver Assistance for Mainstream Vehicles

Forward-facing cameras, integrated with vehicle controls, are being used to recognize pedestrians, signs, and other cars and motorcycles. Automatic brake mechanisms — often connected to a combination of radar, camera, and sensors — can halt a vehicle as it approaches an object ahead. New mounted cameras have the ability to register road markings and keep drivers within their own lanes.

Microscope Camera

The Imaging Source (Charlotte, NC) 13-megapixel microscope camera is equipped with a distortion-free 5.3-mm (35-mm equivalent) auto-focus lens, allowing capture through the ocular, not just a region of interest. The camera can take the place of the ocular or can be screwed into the Cmount. Other features include: Sony Exmor CMOS, 1/2.5” sensor; full image circle capture; full HD at up to 30 FPS; focal length of 5.3 mm; and USB 3.0 interface.

Microscope Confocal Module

Andor Technology Ltd. (Belfast, Northern Ireland), an Oxford Instruments company, has announced the Revolution DSD2, a compact, laser-free confocal module. With the addition of Andor’s CMOS camera technology, the module delivers a large field of view and high dynamic range. The DSD2 uses a broadband white light source instead of lasers, enabling the image of any fluor by selection of filters.
