FCC IDs are usually shown on a label found on a certified radio frequency device and indicates that the device has received a FCC grant of certification. If a device has a built-in display, the FCC ID may be provided electronically. Check the instruction in the User Manual to find the FCC ID information. The FCC rules require that most devices be authorized before they can legally be imported or sold in the United States. These rules also require that labels with the information prescribed by the FCC be affixed or accompany the device. However, not all devices approved for sale and operation by the FCC rules require an FCC ID number.
Internal computer communications consists of digital electronics, represented by only two conditions: ON or OFF. We represent these with two numbers: 0 and 1, which in the binary system is termed a Bit.

Parity is a simple way to error-check. There are Even, Odd, Mark and Space indicators. You can also use no parity. For Even and Odd parity, the serial port sets the parity bit (the last bit after the data bit) to a value to ensure that the data packet has an Even or Odd number of logic-high bits. For example, if the data is 10010010, for Even parity, the serial port sets the parity bit as 1 to keep the number of logic-high bits Even. For Odd parity, the parity bit is 0 so that the number of logic-high bits is Odd. Mark parity simply sets the parity bit to logic-high and Space sets the parity bit to logic-low, so that the receiving party can determine if the data is corrupted.
Binary is the Base-2 numbering system. One byte of data consists of 8 binary digits, from 0000 0000 to 1111 1111. Hexadecimal is the base-16 system, which consists of 16 numbers: 0 to 9 and the letters A to F (decimal number 15).
The Hexadecimal numbering system is useful because it can represent every byte as two consecutive hexadecimal digits, and it is easier for humans to read Hexadecimal numbers than Binary numbers. Most of the manufacturers use Hexadecimal in their protocol documentation. It is simple to convert a value from Hexadecimal to Binary. Just translate each Hexadecimal digit into its 4-bit binary equivalent. E.g. Hexadecimal number F3 equals Binary number 1111 0011.
Decimal refers to numbers in base 10, which is the numbering system we use most in everyday life. It's not as easy as Hexadecimal and Octal to converter Decimal to Binary number, but it is easier for us to understand Decimal.
Octal refers to the base-8 numbering system, which uses just eight unique symbols (0 to 7). Programmers often use Octal format because it is relatively easy for people to read and can easily be translated into binary format: each Octal digit represents 3 binary digits. E.g. Octal number 73 equals to Binary number 111 011.
ASCII (American Standard Code for Information Interchange) is a character encoding based on the English alphabet. ASCII codes (both readable and unreadable) are widely used in communications, such as Modem communications. Letters A to Z and numbers 0 to 9 are readable ASCII codes. Some ASCII codes are unreadable, such as the control codes: XON and XOFF, which are used in Software flow control.
Many serial protocols use checksum (additional bytes added at the end of the data string) to check the data integrity, as errors might occur during data transmission. There are many types of checksum, from the simplest uses of it in Modula or BCC to sophisticated CRC calculation. Using Modula as an example, we learn that before data transmission, the sender adds all command bytes together then mod it by 255 (decimal) to get an additional byte. This is to be added at the end of the command string. When the receiver receives the command string, it will first check the added byte to see whether data remain unchanged or not. If that is the case, it will accept the data, and if not, it will ask the sender to resend the data.

* If your device doesn't have iOS 14 or iPadOS 14 or later and your AirPods are connected to your device, you can find the model number by going to Settings > General > About. Then scroll down until you see the name of your AirPods, and then tap the name.
If you can't use Settings to get your model number, you can find it on your AirPods. The model number is on the first line of the text printed on the underside of each AirPod, or underneath the left cushion of your AirPods Max.

The additional birefringence contrast of polarization-sensitive OCT (PS-OCT) [15,16] can improve the specificity and sensitivity of detection of BCC, as the birefringence properties of normal skin are altered by the onset of BCC tumors [17]. Strasswimmer et al. [17] were the first to report the appearance of aggressive BCC in PS-OCT images and noted smaller values of phase retardation (PR) as a marker for regions showing aggressive BCC characteristics; however, since their preliminary work only included a small number of patients (two), the discriminative power of the proposed marker remains unclear. We recently reported a fully automated support vector machine-based classifier that identifies BCC in ex-vivo mice skin samples from PS-OCT images with high sensitivity and specificity (92.5% and 94.4%, respectively) [18]. The results confirmed that a classifier for BCC based on combined intensity and birefringence features outperforms a classifier based on intensity alone.
Table 1 summarizes the final dataset after post-processing and adjustments. Note that 10 patients contributed both healthy and BCC data, while for a different group of 16 patients we only obtained healthy data, and for another group of 16 patients we only obtained BCC data. Thus in total we included data from 42 patients. Additionally, depending on the physical sample size, the number of collected PS-OCT images varied significantly among patients. However, to avoid biasing our dataset towards patients with a larger number of collected PS-OCT images, we only retained ten PS-OCT images per type (healthy or cancerous), per patient. The smallest number of labeled images for any patient was ten, which set the upper bound for all patients. For patients yielding more than ten labeled images, ten images were picked randomly to keep in the dataset.
Process for calculating all intermediate Ascan-based features from representative (a) intensity and (g) PR Ascans. In all images, dashed-red lines represent fitted lines, except in (h) where the dashed-red curve represents a fitted 5th-order polynomial. Vertical dashed-black lines represent the fitting ranges. Long-range intermediate features are calculated by fitting (b) a line to intensity and (h) a fifth-order polynomial to PR Ascans. Short-range intermediate features are calculated by fitting lines to data selected by an axially-moving window. The red rectangles represent the first window, and the window is translated axially (red arrows) in one-pixel steps. Peaks and valleys intermediate features are calculated from axially flattened (d) intensity and (j) PR Ascans. Blue and green lines represent peaks and valleys, respectively. Segment intermediate features are calculated by fitting lines to (e) intensity and (k) PR Ascans segments defined by local maxima (blue triangles) and local minima (inverted green triangles). Crossing intermediate features are calculated by counting the number of times (f) intensity and (l) PR Ascans cross predefined crossing levels (dashed horizontal lines). INT: intensity and Norm.: normalized.
Up to this point, the selected feature subset (i.e., SmRMR,100) had only been optimized with respect to the label vector and the original feature set, but not with respect to the selected machine-learning algorithm. Using the forward search algorithm we further optimized the feature subset by selecting only those features that were optimized for SVM_GS4 (Sfwd). This final future set should yield the most accurate classifier when used with SVM_GS4. We ran the forward search algorithm on SmRMR,300 with 94 and 206 intensity and PR features, respectively. 2ff7e9595c
