1. A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by “shifting” the signals between stages within the device one at a time. CCDs move charge between capacitive bins in the device, with the shift allowing for the transfer of charge between bins.
2. An airline meal or in-flight meal is a meal served to passengers on board a commercial airliner. These meals are prepared by airline catering services.
The first kitchens preparing meals in-flight were established by United Airlines in 1936.
These meals vary widely in quality and quantity across different airline companies and classes of travel. They range from a simple beverage in short-haul economy class to a seven-course gourmet meal in long-haul first class.
3. A paper cup is a cup made out of paper and often lined with plastic or wax to prevent liquid from leaking out or soaking through the paper. It may be made of recycled paper and is widely used around the world.
4. The trumpetis the musical instrument with the highest register in the brass family. Trumpets are among the oldest musical instruments, dating back to at least 1500 BC. They are played by blowing air through closed lips, producing a “buzzing” sound which starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have been constructed of brass tubing, usually bent twice into a rounded oblong shape.
