Base32 (also known as duotrigesimal) is an encoding method based on the base-32 numeral system.It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (2 5).
IBM 80 Electric Punched Card Sorting Machine, model 1, Introduced by IBM in 1925, 450 cards per minute. [3] This sorter was almost twice the speed of the older Hollerith 70 vertical sorter and used an entirely new magnetically operated horizontal design. At the close of 1943, IBM had 10,200 of these units on rental.
Many incremental encoders have an additional output signal, typically designated index [2] or Z, [3] which indicates the encoder is located at a particular reference position. Also, some encoders provide a status output (typically designated alarm) [4] that indicates internal fault conditions such as a bearing failure or sensor malfunction.
ARINC 615 defines a high-speed data loader protocol layered upon the ARINC 429 physical layer. ARINC 629 defines a high-speed, multi-transmitter, TDMA extension to ARINC 429, superseded by AFDX . ARINC 664 Part 7 defines the use of a deterministic Ethernet network as an avionic databus in later aircraft like the Airbus A380 and the Boeing 787 .
For example, when used as an address decoder, the 74154 [3] provides four address inputs and sixteen (i.e., 2 4) device selector outputs. An address decoder is a particular use of a binary decoder circuit known as a "demultiplexer" or "demux" (the 74154 is commonly called a "4-to-16 demultiplexer"), which has many other uses besides address ...
Each individual light sensor in the CCD reader is extremely small, and because there are hundreds of sensors lined up in a row, a voltage pattern identical to the pattern in a barcode is generated in the reader by sequentially measuring the voltages across each sensor in the row. The important difference between a CCD reader and a pen or laser ...
For example: a 16-bit Short Serial Message Format transmits a 16 bit message across 16 Fast Channel message "frames". The message consists of: a 4 bit Message ID, 8 bits of data, and a 4 bit CRC code. It's encoded by bit 3 (the MSB) of the Status nibble being 1 for the first frame of the message, and zero for the following 15 frames.
Position sensors measure the location of an object, while acceleration sensors measure the rate of change of velocity. Velocity sensors provide real-time speed information, often used to track or control movement accurately. This capability makes them valuable in applications where speed monitoring is more critical than position or acceleration.
