摘要:
Disclosed herein is a system comprising: a hydrogen fuel cell; a fuel storage tank; a regulator coupled to the storage tank and the fuel cell; an electronic auto pilot; a rechargeable battery; a power electronics module for delivering power from the fuel cell to the autopilot and the battery; and a heat exchanger coupled to the fuel cell. The fuel cell is characterized by: a minimum continuous power output of no more than 25 W; a maximum continuous power output of no less than 5000 W; a specific power of at least 200 W/kg based on the mass of the fuel cell and any control electronics, cooling components, air delivery components, and water management components; an ability to operate at least 2 psig of hydrogen at an inlet; and an ability to operate at temperatures up to 90° C.

This invention relates to systems and methods for managing livestock, such as cattle, from conception to consumption. More particularly, this invention relates to systems and methods in which users, such as producers, feedlot managers, packers, buyers, sellers, and consumers, are brought together through shared information and improved communication. Users may access one or more applications, tools, and/or systems to increase the value of each animal, monitor and track each animal, and improve the efficiency of their operation.

According to the present invention there is disclosed a system and a method for detecting the presence of human fecal contamination on objects, such as a protein source, a worker's hands, work surfaces, tools or utensils. In one embodiment, there is included a supporting structure which supports a diffuse light source, the light source emitting light having a wavelength from the blue portion of the electromagnetic spectrum effective to elicit fluorescence from the fecal matter at wavelengths in the 600 nm to 800 nm range. A third wavelength of interest in the 600 nm to 800 nm range is also used as a reference control. Thereafter the wavelengths are combined in a series of mathematical steps to develop an algorithm or process to detect the presence of the human fecal material. There is also disclosed a method of using such a device to detect the presence of such contamination, optionally including further steps to identify the source of any contamination and to modify any practices so that the spread of contamination may be reduced.

A method and apparatus for the detection of pits and abnormalities in various stone fruits. The apparatus transmits a first plurality of beams of light (18) across inspection zone (14) and transmits a second plurality of beams of light (22) across inspection zone (14) in a direction opposite to beams of light (18). As a stone fruit (10) passes through inspection zone (14), a first plurality of sensors (32) and a second plurality of sensors (34) detect the variations in the intensity of the transmitted beams of light. The light transmittance and reflectance characteristics of the stone fruit are analyzed to detect the presence of a pit or internal or external abnormality.

A fuel cell includes a catalyst coated membrane with a proton exchange membrane, a cathode layer disposed on a first surface of the proton exchange membrane, and an anode layer disposed on an oppositely disposed second surface of the proton exchange membrane. At least one gas diffusion layer is bonded to at least one of the cathode and anode layers of the catalyst coated membrane. At least one bonding layer substantially surrounds at least one of the catalyst coated membrane and the at least one gas diffusion layer. The at least one bonding layer is bonded to a portion of the proton exchange membrane. At least one circuit is bonded to a portion of the gas diffusion layer and a portion of the at least one bonding layer.
