摘要:
An automated gravimetric screening system and method controls soil moisture in a plurality of potted plants to perform water deficit experiments in a greenhouse using a stationary support platform and pot design that maintains the plants in a static location during the testing. By weighing and re-watering the pots from beneath the platform, the present system and method permits an upper gantry to capture high resolution images, temperature data, or other sensor data to quantify the plant stress level or plant canopy characteristics during the experiment.

摘要:
A sensor used to measure temperature or concentration of a combustible gas. The sensor includes an optical head that picks up infrared information emitted by the combustible gas. The infrared information is conveyed from the optical sensor through a diffracting device onto a strip of photodetectors. A processor receives the information garnered by the photodetectors and determines the concentration and temperature profile of the combustible gas based on a stored thermodynamic model, radiation behavior, varying the thermodynamic parameters, and comparing a calculated spectrum with the measured spectrum. The sensor additionally has elements, such as cooling devices and casing to make it suitable for use with aviation where altitude creates problems with known methods of gas temperature analysis.

A communication technique includes broadcasting a signal that indicates at least a plurality of protocols supported by the device that broadcasts the signal. In a disclosed example, the device that broadcasts the signal is also capable of receiving broadcast signals from other devices. In one example, the broadcasting device is a mobile station while in another example the broadcasting device is a base station. Devices that receive the broadcast signal can then establish a communication connection using one of the indicated protocols when desired. Disclosed examples include broadcast signals indicating available protocols for mobile station-to-mobile station communications, base station-to-base station communications and communications between mobile stations and base stations.
