CDC recommends that seasonal influenza vaccine be administered to all age groups as soon as it becomes available. Antibody to seasonal inactivated influenza vaccine declines in the months following vaccination. However, antibody level at a point several months after vaccination does not necessarily correlate with clinical vaccine effectiveness. There are no studies that compare vaccine effectiveness according to the month when the vaccination was given. The authors of a review on antibody declines among the elderly after vaccination reported, "In conclusion, we found no compelling evidence for more rapid decline of the influenza vaccine-induced antibody response in the elderly, compared with young adults, or evidence that seroprotection is lost at 4 months if it has been initially achieved after immunization." (See Skowronski, et al., Rapid Decline of Influenza Vaccine-Induced Antibody in the Elderly: Is it Real, or Is It Relevant? Journal of Infectious Diseases 2008;197:490-502).In addition, there is a lack of evidence for late-season outbreaks among vaccinated persons that can be attributed to waning immunity.

WE HAVE NOTICED THAT CDC RECOMMENDS BEGIN VACCINATING WITH SEASONAL INFLUENZA VACCINE AS EARLY SEPTEMBER OR EVEN EARLIER. DOES PROTECTION FROM DECLINE WANE WITHIN 3 4 MONTHS OF VACCINATION? SHOULD I WAIT UNTIL OCTOBER NOVEMBER TO VACCINATE MY ELDERLY MEDICALLY FRAIL PATIENTS?

Yes. You are referring to Afluria, which is manufactured in Australia by CSL Laboratories for the U.S. market. CSL's 2010 Southern Hemisphere influenza vaccine (Fluvax and Fluvax Junior) has been associated with increased post-marketing reports of fever and febrile seizures in children predominantly younger than age 5 years as compared to previous years. For this reason, on August 5, 2010, ACIP recommended that Afluria, 0.5 mL, licensed for use in people age 36 months and older, not be used in children younger than age 9 years. ACIP further recommended that Afluria could be administered to children ages 5 through 8 years who are at high risk for influenza complications if there is no other age-appropriate TIV available, after risks and benefits of using this vaccine in this age group have been discussed with the parent or guardian. The vaccine should not be given to children younger than age 5 years. For detailed information, go to www.cdc.gov/media/pressrel/2010/s100806.htm.

The child should always receive the dose appropriate for his or her age at the time of the clinic visit; at age 37 months that would be 0.5 mL.

There are several reasons why this misconception persists: (1) Less than 1% of people who are vaccinated with the injectable vaccine develop flu-like symptoms, such as mild fever and muscle aches, after vaccination. These side effects are not the same as having influenza, but people confuse the symptoms. (2) Protective immunity doesn't develop until 1–2 weeks after vaccination. Some people who get vaccinated later in the season (December or later) may get influenza shortly afterward. These late vaccinees develop influenza because they were exposed to someone with the virus before they became immune. It is not the result of the vaccination. (3) To many people "the flu" is any illness with fever and cold symptoms. If they get any viral illness, they may blame it on the flu shot or think they got "the flu" despite being vaccinated. Influenza vaccine only protects against certain influenza viruses, not all viruses. (4) The influenza vaccine is not 100% effective, especially in older persons.

BYCNC Response:
This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

Yes. Influenza vaccine commonly contains three influenza vaccine virus strains; two for A viruses and one for a B virus which are prepared based on circulating viruses from the previous influenza season. Infection from one virus type does not confer immunity to other types and it would not be unusual to have exposure to more than one type during a typical influenza season. By all means, vaccinate this person!

IF AN UNVACCINATED PATIENT HAS JUST RECOVERED FROM A DIAGNOSED CASE OF INFLUENZA COMES INTO OUR CLINIC, SHOULD WE VACCINATE HIM?

A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

It is never too early to begin planning for the coming fall's influenza vaccination program. The most important thing you can do initially is to place your order for vaccine from your usual source. Some manufacturers often stop taking pre-orders in mid-May. Be sure to include vaccine for pediatric patients needing two doses and also for your facility's healthcare workers as part of your overall campaign.

I would first check the mechanical parts to ensure smooth motion. Is your machine bogging down during cutting or jogging/rapids?

You can increase the voltage to gain a higher speed for rapids/jogging, but make sure the driver can handle this voltage. There should be a max voltage on the driver label.

If the bogging down is happening during cutting, either reduce the cutting depth or switch out the drive and motor for the axis that is giving the problem.

This will depend on the VFD you have to identify the correct terminal. The terminal on the VFD will be labeled AI1 typically (Analog Input #1). You will also need to make sure to complete the PWM circuit using the GND terminal on the VFD.

Additional Information:
I have wired my 0-10V signal to the AI1 and GND terminals as suggested. I have also set the PD-01 and PD-02 settings to 1. Still nothing. Is there something else that I am missing?

Additional Information:
Thanks for the information. Can you let me know the model of the VFD that you have?

Additional Information:
VFD Model # YL600-2S-2K20

Additional Information:
Thanks. I will check our resources and documentation to see if there is another programming setting that needs to be changed.

Additional Information:
Does your VFD have a VI terminal?

Additional Information:
No, it does not. The terminals for this VFD are as follows (seperated by dashes "-").

10V-AI1-AO2-PLC-DI5-DI3-DI1-COM
AI2-GND-AO1-DI6-DI4-DI2-FM-24V

Additional Information:
Do you have a PD070 parameter?

PD070 is the main Analog Input parameter.

The options for that parameter is:
0: 0-10V
1: 0-5V
2: 0-20mA
3: 4-20mA
4: 0-10V (4-20mA Stacked)
5: XIA
6: (VI+XIA)/2
7: (3VA+XIA)/4
8: (XIA_XIB)/2
9: Max (XIA, XIB)
10: Min (XIA, XIB)


Additional Information:
There is a PD-00 thru PD-09. PD-07 is currently set to 0.

Additional Information:
It appears that the manual I’m using “Titled YL600” is not the same as your unit. I will check our manuals and find the one that has only PD-00 to PD-09.

Additional Information:
For that VFD, the parameters are P0. The 0 may look like a D on the display.

ACIP's influenza recommendations for children age 6 months through 8 years have changed for the 2011–12 season. According to the new algorithm, certain children need 2 doses of influenza vaccine this influenza season, separated by at least 4 weeks. Here is a summary:

• Children age 6 months through 8 years who did not receive AT LEAST 1 dose of the 2010–11 vaccine should receive 2 doses, separated by at least 4 weeks, REGARDLESS of their previous influenza vaccination history.
• Children age 6 months through 8 years whose influenza vaccination status from the previous season is not known should also receive 2 doses at least 4 weeks apart.
• Children age 6 months through 8 years who received 1 dose of seasonal influenza vaccine during the 2010–11 season need ONLY 1 dose this season. This is because the vaccine strains are the same this season as last season.

WHICH OF OUR PEDIATRIC PATIENTS WILL NEED 2 DOSES INFLUENZA VACCINE FOR THE 2011–12 VACCINATION SEASON?

Peak influenza activity does not generally occur until February. Providers are encouraged to continue vaccinating patients throughout the influenza season, including into the spring months (e.g., through May), as long as they have vaccine in the refrigerator and unvaccinated patients in their office.

Because influenza occurs in many areas of the world during April through September, vaccine should be given to travelers who missed vaccination in the preceding fall and winter. Another late season use of vaccine is for children younger than age 9 years who were vaccinated for the first time in the current vaccination season but failed to get their second dose. For each of these situations, vaccine can be given through the month of June since injectable influenza vaccine customarily has a June 30 expiration date.

Strictly to the point. Assuming:
-You have a working linuxcnc install with a compatible parallel port
-You have wired Bread-Out Board V5 to the motor drivers so you know which pins are for which signals(watch video tutorials for that on this site)
-You have wired motors to motor drivers (watch video tutorials for that on this site)

a)We need to know the base parallel port addres, for that you need to input on a linux terminal the command:

#lspci -v

You can scroll up and down the result with page up and page down. Look for a "Parallel Port..." line, the value you are looking for is the "I/O Ports at.." Write them down

To get the Base Period Maximun Jitter, go to
applications - cnc - Latency Test

Now you should let that window running for a while, so it calculates an accurate jitter, go watch the tutorial videos for the connections between the Bread-Out Board and the motor controllers.

After its been running for half an hour or so with the machine in use, write down the calculated jitter values, mine was Servo Thread - 39000

Now close the Latency test dialog

b)Go to applications - cnc - stepconfwizard
"START" - Create a new config
Check - Create Desktop Shortcut to config files
Check - Create Desktop Shortcut to start linuxcnc with this config
FORWARD

c)"BASE INFORMATION"
Fill in a Machine Name that suits you
Bluechick is XYZ on inches
Fill in the Base Period Maximun Jitter with the value obtained in "a)"

FORWARD

d)If you watched the tutorials on a) and b) you know the pin numbers for your signals.
Parport Base Address you need to put the value obtained in a), mine was cf00
Output pinout presets I used Sherline

FORWARD
FORWARD

e)Axis X (chain and sprocket axis)
Data for bluechick from build yourcnc
Motor Steps per revolution 200
Microstepping 64 (that if you followed tutorials, change if you have different)
Pulley teeth 1 ; 1
Leadscrew Pitch 0.444444 (that value comes from 1rev / (.25 in * 9 teeth))
Maximun Velocity 10
Maximun Acceleration 0.5
Home location 0.0
Table travel 0.0 to 34.0 (maybe you want to change this later)

Now, you can do "Test this axis" and jog it (move it!) Try to position everything in the middle (you will be doing it axis by axis) and select
"+ 0.5 in" Hit run, I used a pencil held at the gantry and paper to draw a line, then confirmed that the measurement was 0.5 in. Also tried with "+/- 0.5 in" and confirmed 1" measurement

FORWARD when happy with your Axis X

Repeat for Axix Y but the table travel is 0.0 to 12.0

f)AXIS Z

Motor Steps per rev 200
Driver Microstepping 16 (as recommended for lead screw)
Pulley teeth 1 ; 1
Leadscrew Pitch 2
Max Vel 2.5

Table travel 0.0 to 3.5

Test, and FORWARD when happy

g)After configured you can go to
Applications - cnc - LinuxCNC, and there you go...
