Common-Emitter Current Gain
Common-emitter current gain or static current gain is expressed as hfe. It is defined as the ratio of the input dc current and the output dc current of the transistor. This parameter is also known as . The ratio of collector current to base current, ß is the fundamental parameter characterizing

Sensor Sense: Ultrasonic Double-Sheet Detectors
or more sensors used in the same vicinity may produce mutual interference, disrupting the operation of both sensors. Likewise, the ultrasonic signal should not pass around the detected material. The most common cause of pass around is via reflections of the ultrasonic beam from large surfaces

737 Spacious, Modern Replacement For EP-3
to the death of the Army/Navy Aerial Common Sensor contract offered by Lockheed Martin. Playing off the basic P-8A Multimission Maritime Aircraft (a 737-800 with a longer 737-900 wing), Boeing officials say they will already have a hot production line (ITAR compliant for classified military work), a proven

solid-state diode. As with a common diode, the material is classified as N-type and P-type. When placed in direct contact, the two different materials create a region called the PN junction. When an electric current of sufficient voltage and polarity is applied to this junction, electrons in the N-type

Sensor Sense: Ultrasonic Double-Sheet Detectors
. The most common cause of pass around is via reflections of the ultrasonic beam from large surfaces on the machine. Those surfaces may need a layer of sound-absorbing material. Other applications for these sensors include ultrasonic splice detection that senses a splice in high-speed web applications

Fundamentals of the Infrared Physical Layer
Infrared light, commonly referred to as "IR", is a common, easy-to-use, low power and low-cost media to transmit information. Among the few "wireless" communication choices, IR has the significant advantage of compatibility with hundreds of millions of electronic devices with IR ports (i.e., laptop
