Check Digit
Binary digit. One bit is the basic unit of binary information.
Generally, eight consecutive bits compose one byte of data.
The pattern of 0 and 1 values within the byte determines its
meaning.
A unique 12-character hexadecimal, IEEE 48-bit address
(BT_ADDR) that represents a Bluetooth device.
A sub-system containing Bluetooth RF, baseband, resource
controller, link manager, device manager, and Bluetooth
HCI.
A device that is capable of short-range wireless
communication using the Bluetooth system.
Abbreviation for Bluetooth. Bluetooth protocol is a
predefined rule that sets out a specific system for devices
to communicate with each other and a protocol stack is the
layering of the protocols that are used in a specific
technology. The Bluetooth Radio protocol operates in the
2.4GHz ISM band.
Standard for Bluetooth radio transmission for a range of up
to 100m.
Standard for Bluetooth radio that restricts the transmission
range to 10m in order to reduce the effect of the radio on
neighboring wireless systems.
A sequential series of bits comprising one character and
handled as one unit. Usually encoded in the ASCII format, a
byte usually consists of eight bits and represents one
alphabetic or special character, two decimal digits or eight
binary bits.
Center for Devices and Radiological Health. A federal
agency responsible for regulating laser product safety. This
agency specifies various laser operation classes based on
power output during operation.
This is the lowest power CDRH laser classification. This
class is considered intrinsically safe, even if all laser output
were directed into the eye's pupil. There are no special
operating procedures for this class.
No additional software mechanisms are needed to conform
to this limit. Laser operation in this class poses no danger
for unintentional direct human exposure.
A pattern of bars and spaces which either directly
represents data or indicates a control function, such as a
number, letter, punctuation mark, or communications
control contained in a message.
Those characters available for encoding in a particular bar
code symbology.
A digit used to verify a correct symbol decode. The scanner
inserts the decoded data into an arithmetic formula and
checks that the resulting number matches the encoded
check digit. Check digits are required for UPC but are
optional for other symbologies. Using check digits
decreases the chance of substitution errors when a symbol
is decoded.
