Home Blood Pressure Monitors: How to Properly Use A Monitoring Device

October 5, 2015

Checking your blood pressure doesn’t always require a trip to the doctor’s office. In fact, home blood pressure monitors make it possible to test your blood pressure from the comfort of your living room. These wearable devices make it possible to regularly monitor blood pressure for abnormalities, caused by hypertension or heart disease.

There are three main types of blood pressure monitoring devices: Arm band blood pressure monitors, wrist monitors and finger monitors. Arm band monitors provide the most precise measurements, while wrist and finger monitors provide a greater level of convenience for users. Whether you’re suffering from hypertension, heart disease or your doctor has recommended that you regularly monitor your blood pressure, a wearable monitor might be right for you.

How Often Should You Check Your Blood Pressure?

In general, healthy young people should have their blood pressure measured every five years, but as we age, it’s important to have our blood pressure monitored as regularly as once per year. Adults who have preexisting conditions like heart disease, hypertension or diabetes may be required by their doctors to monitor blood pressure as frequently as twice per week.

Early morning, before you have taken blood pressure medications, is the best time of day to test for more precise readings. Always be sure to check with your physician to ensure your monitor is properly calibrated and for a schedule for home monitoring your blood pressure.

How to read the numbers? The blood pressure monitor gives a reading of two numbers a systolic and diastolic number. A reading for instance would read 120-over-80 mm Hg, with 120 being pressure in the heart’s arteries when it is pumping and 80 referring to the pressure between beats. In general, optimal blood pressure is below 120 over 80 mm Hg. If either the number is above the optimal level, you may have abnormal blood pressure; above 140-over-90 is considered hypertension.

Questions to Ask When Choosing a Blood Pressure Monitor

Does the arm band fit? The band should fit properly around the arm or wrist. A band that is too tight may not provide proper readings.
Is this right for your needs? Consult with your doctor to determine which type of monitor will provide you what you need.
Is the monitor validated? Blood pressure monitors are validated by a variety of healthcare organizations. Non-validated monitors, though, may be more cost-effective while providing accurate testing.

Multichannel Video Recorders: NVR vs DVR and Installation

September 30, 2015 Leave a comment

Multichannel video recorders are commonly used in surveillance camera systems to record and capture video. All video capture by your home or business’s security cameras is routed to the multichannel recorder, and the recorder in turn stores the video so that you can re-watch it later. Depending on the type of cameras that you use, you will likely use an NVR (network video recorder) or DVR (digital video recorder) multichannel recording system.

So what are multichannel recorders and how do they work? Multichannel refers to the number of inputs – or the number of cameras – that a NVR or DVR can handle. If you use 4 home security cameras, for example, you would require at least a 4-channel NVR or DVR. Today, multichannel recorders can accommodate a growing number of cameras, with high-end models having 64 channels or more.

Here’s how multichannel recorders work: NVR systems work with IP security cameras. The data that is captured on the camera is then sent wirelessly to the NVR, where it is captured. DVRs are used with analog systems. The cameras must be attached via a VGA cable to the DVR. Once the video is sent to the NVR or DVR, it is typically stored on a hard disk, USB thumb drive, or on network storage.

NVR vs DVR: Advantages, Differences and Specifications

The biggest difference between NVR and DVR recorders is the process in which they capture and record video. NVRs are compatible with IP or TCP cameras, which are cameras that can connect to the Internet. In these systems, the video is decoded at the camera and then sent wirelessly to the NVR. With DVRs, the video signal is sent directly to the DVR where the analog video is converted to digital. DVRs require that the camera to be linked directly to the DVR hard drive via a video cable.

Remote Viewing: Both NVR and DVR accommodate online viewing, meaning the video from the camera can be watched remotely.
Compatibility: NVR systems are only compatible with IP cameras. DVR systems, on the other hand, are compatible with a wider range of cameras. A tip: Be sure the cameras you purchase are compatible with your NVR or DVR system.
Video Quality: With NVR systems, the video is compressed at the camera and then sent wirelessly. Because of this, IP cameras perform better and deliver more resolute pictures. Full HD is possible with NVR systems.
Camera Placement: NVR systems are more flexible for camera placement, as the only requirement is that the camera is on the LAN network. With DVR systems, cameras must be placed closer to the DVR – typically about 1,000 feet or less.
Consistency: Networked IP cameras do take up bandwidth, and they are connected to the Internet. So they are affected by Internet outages or overuse of the bandwidth. Conversely, DVR systems will always capture video, and they’re often capable of running on batteries in the event of a power outage. Thus, their recordings are more guaranteed.

Multichannel Recorders: Installation Tips

In general, DVR and NVR systems have detailed instructions for installation. The good news: They can be set-up by anyone. You don’t need advanced knowledge of technology to set up your systems, although NVR connections are a bit more of a challenge to set-up. Typical set-up includes:

Each system is different, yet typically the process begins with installing the NVR or DVR unit. Some IP cameras must be connected to a POE, or Power over Ethernet, switch. This provides power to the camera.

In an NVR system, each camera is connected via an Ethernet cable to the POE switch, which is connected to a wireless router. The router then connects to the NVR system, so the data from the cables can be captured. In a DVR system, each camera is connected directly to the DVR system via a wired connection.

Microstep Motors: How They Work

September 25, 2015 Leave a comment

Stepper motors – which are often called step motors – are small electric engines that are widely used in a variety of industrial and electrical applications. For example, stepper motors are often used in computer CD drives to move the laser reader. These motors have an attached spindle, which revolves when the motor is sent an electrical pulse. Within the motorhead there are small “steps,” between 200 to more than 50,000, which are small groves that direct the spindle. In effect, the spindle revolves “step-by-step” and can be stopped precisely at one of these steps.

One of the newest and most commonly used is a microstepper motor. Microstep motors are similar to step motors in the way that they are powered, i.e. the motor is sent an electrical pulse which powers the spindle. Yet, the biggest difference is that microstep motors are more precise. These motors, for example, further divide up the traditional motors’ 1.8-degree steps into 256 microsteps. This results in 51,200 steps per revolution, compared to just 200 with a full-step motor. This allows for much more accurate positioning and decreases the likelihood of motor resonance, which is a very common issue.

Common Uses and Advantages of Microstepping Motors

Microstep motors, due the preciseness of the spindle’s revolutions, are commonly used in industrial or electrical applications that require exact position. Further, because they have many more steps, compared to full-step motors, the movement of the spindle is more fluid, resulting in a decrease in resonance. Due to their exactness and fluidity of motion, micro step motors are commonly used in:

Printing and plotting machines
Robotics
Machining tools
Pick and place machines
Automated cutting devices
Automated packaging devices
Micro Stepper Motor – miniature

Step motors, in general, have a number of advantages over different kinds of electrical motors. For example, due to the frequency of the impulse that is sent to the motor, step motors can produce a wide variety of rotational speeds. They can also provide: Low-speed motion, long-lasting performance, greater control over stopping, starting and reversal, powerful torque at low speeds, and extremely precise positioning.

Access Doors and Access Panels: Types, Install, and Considerations

September 22, 2015 Leave a comment

Access panels are a commonly used building device that provide easy access to plumbing, electrical, HVAC or duct systems. An access door or panel is installed into the existing drywall, mortar, tile or ceiling, and they have concealed-hinge or snap-in-place doors that open to plumbing valves, wiring or duct systems encased in the wall.

Typically, access panels are installed during the initial construction of a home or commercial building. But often, due to plumbing, electrical or HVAC renovations, new access doors must be installed to provide electricians, plumbers or HVAC technicians with convenient access to concealed systems. There are many different types of access doors, and there are several considerations that installers must make to ensure the door they purchase works properly.

If you’re planning on installing an access panel in your home or office, here are a few things you should know:

Access Panels and Doors: Types and Considerations

Access panels are constructed from a variety of materials, including steel and aluminum, sturdy plastic, and gypsum board. They’re available in many different sizes and colors, which help installers match the access panel to the existing wall finish. Typically, steel, aluminum and wooden access panels can be painted to match the existing wall color, as well.

Aside from material, color and size, the biggest consideration is weight. Drywall and gypsum – a material often used in the construction of ceilings – aren’t the sturdiest building materials, which makes it difficult to attach an access panel made from heavy steel or aluminum. More lightweight options like gypsum ceiling panels or drywall-specific access doors are designed for these types of installations. When considering an access door for weight, determine the type of material it will be attached to, as well as the anchoring system. Types of access panels include:

How Do I Install a Drywall Access Door?

Installing drywall access panels is a quick, convenient DIY job that requires just a few tools and very little carpentry expertise. The majority of access doors that are available come with installation directions, but often, installation steps are fairly similar:

Measuring – Access doors typically come with a template to help installers measure the hole. Doors can be installed flush or picture frame. Picture frame means the frame is installed on top of the existing drywall, while flush means the frame is installed within the wall. Flush installations require more accurate measurements.
Cutting – To cut drywall, you will need a jab saw. To cut around your outline, you can push the jab saw through the existing drywall or create starter holes with a drill.
Sanding – Once, you’ve cut the holes, it’s important to sand the edges. This will ensure your frame fits securely in the hole.
Anchoring the Frame – The frame can be anchored in one of three ways: Via an anchor screw in the drywall, with adhesive, or by a tape bead that comes prepackaged on the frame. Tape beads and adhesive are typically used for lightweight access doors, while anchor screws, which prevent screws from slipping from the drywall, are used for heavy duty frames.

Formaldehyde Monitoring: When to Use a Formaldehyde Monitor?

September 17, 2015 Leave a comment

Formaldehyde is a widely used industrial chemical, and when people are exposed to it in high volumes, it can be very dangerous. Because of this, workplaces that use the chemical require periodic formaldehyde monitoring to ensure workers safety.

Yet, formaldehyde exposure can also occur in the home, as well. Building and flooring materials, as well as furniture, foam insulation and gas stoves, may all release formaldehyde into the air. Fortunately, though, exposure is typically at a minimum. Yet, when formaldehyde-containing materials like composite woods and particle board are used in high volume and the home is poorly ventilated, the risk for exposure increases.

Formaldehyde monitoring is recommended when purchasing a new home, and this is especially important for owners of mobile homes. Mobile homes – due to the materials they are built with and poor ventilation– have been known to expose habitants to higher than normal levels of formaldehyde, resulting in health complications for residents. The CDC has found that formaldehyde levels in mobile homes are five times above normal levels.

Formaldehyde Monitors: Testing the Air in the Home and Workplace

Formaldehyde can be found in a range of products, including plywood, paneling, pressed wood, particle board, and some foam insulating materials. It is also released when materials are burned like when you use a natural or wood stove. Yet, just because you use a wood stove, or have cabinets made of pressed-wood, you aren’t necessarily at risk.

Typically, exposure in the home should be limited to .10 ppm. Below these levels, most people are at little risk for related health complications. For the workplace, the OSHA has specific guidelines. They state that .50 ppm calculated for an 8-hour shift requires action. For more information, see specific OSHA guidelines.

So when is formaldehyde monitoring necessary? Here are a few tips:

At home:

Are you moving into a new home? When moving into a new home, especially those that are new construction or have undergone extensive remodeling, it may be beneficial to monitor for formaldehyde. New materials containing the chemical release more of it, but overtime, materials off-gas most of the chemical and release it in much lower volumes. Thus, newly constructed homes are likely to release it in greater volumes.
Are you experiencing symptoms? Symptoms include respiratory issues, throat irritation and coughing, as well as dizziness, headaches and nausea. Plus, the eyes are particularly sensitive to exposure, which causes a burning sensation. If symptoms are chronic, you should monitor your home.
Have you remodeled recently? New construction materials release formaldehyde in greater volume. To prevent this from happening, you can “off-gas” the chemical by leaving new materials in an open-air space for an extended period. If you experience symptoms following a remodel, you should conduct a test.

In the workplace:

Do you suspect exposure? If workers are experiencing symptoms, employers should conduct testing to determine if they are being overexposed. Exposure might be caused by a faulty ventilation system, a chemical spill or industrial fire. In these cases, employers should conduct testing.
formaldehyde warning
Have you conducted initial tests? When formaldehyde is in use in industrial facilities, the OSHA requires that an initial test is conducted to determine baseline exposure levels. If they’re above OSHA guidelines, more regular testing may be needed.
Are you due for a yearly test? Following an initial test, the OSHA requires facilities to conduct regular testing. In general, the monitoring should happen annually. But if levels are above the .50 ppm threshold, testing is required more frequently.
