Automotive Load Managers For Emergency Vehicles

Automotive load managers for emergency vehicles are designed to monitor and control the transfer of electrical energy in an automotive system. The most advanced load managers will incorporate load sequencing and load shedding functions. These two functions will help maintain the vehicles optimal electrical state, which is paramount for any emergency vehicle.

The load sequencing function is used to turn all selected loads ON or OFF from on central switch. Loads can be anything from, emergency lights, sirens, A/C, radios, etc. When electrical loads of the type encountered in an automotive application are switched ON or OFF they create large current and voltage fluctuations in the electrical system in which they are connected. The larger the current consumption of a load, the greater the impact the load has in the generation of electrical transients or line noise when the load is energized or deenergized (Turned ON or OFF).

These current fluctuations, in turn, contribute to the generation of voltage spikes of a magnitude that is high enough to damage sensitive electronic devices connected to the electrical system. This would be the last thing you want while riding in an emergency vehicle. The load sequencing function of a good load manager will allow you to turn all the selected loads ON or OFF from one location to minimize electrical disturbances and the effect this action may have upon the rest of the electrical system. The load shedding function is used to monitor the voltage level of the vehicles battery. If a decrease in the battery voltage is sensed, the load manager will start shedding loads. A good load manager will allow you to program what loads and in what sequence they will be shed. One the loads battery voltage returns to its normal value, the loads that were previously shed are switched on.

The examples in the previous paragraphs were for when a vehicle is in motion. If the vehicles alternator is not supplying enough power when the vehicle is idling, the load manager should have a high idle function which will send a signal the vehicles engine speed control to set the idle speed to a higher level. An action equivalent to pressing the accelerator while in park. The higher engine speed is maintained until the battery voltage returns to normal or until the engine is no long idling.

Do it Yourself Emergency Power

As we look toward the future, the ever looming signs of the failure of the electrical grid are becoming more and more irrelevant. The failure of the grid will cause widespread outages and will leave you in the dark without you have a plan. Remember the Northeast blackout of 2003?

A plan to circumvent the dark is priceless. Imagine for a moment what you could do with the barest of equipment. A household with a Deep Cycle battery, Inverter and a power strip has the makings of their own Power Plant. These items will allow you to have the light you will most respectfully seek when the lights go out and you do not know where your flashlights are. You do have a flashlight do not you? These 3 items are the beginnings of your own electrical grid.

Imagine the feeling you will have when you connect your inverter to your Deep Cycle battery and plug in your lamp and you produce light. You now have this convenience without the noise and smell of an external generator. You have now become your own electric company. The satisfaction of making your own electricity is akin to making fire for the first time.

Now that you have a small alternate power system you need a way to recharge your battery. Now add to your system a battery charger in the form of a small "Amorphous" solar panel and you have a renewable source of energy that is FREE! A 15 watt "Amorphous" solar panel will last for years without any upkeep other than brushing them off every now and then.

The process of making your own electricity is easy and you do not have to be a "techie" or a "geek" to understand it. A few simple pieces of equipment and you have the tools to make renewable energy. Now that IS a great feeling! You are helping the environment by offsetting your carbon footprint by a small amount and doing your share to bring forth light when you are in the Dark.

Home Emergency Kits to Prepare You for Anything

A disaster can occur at any time and without any warning whatever. There may also be other difficulties that can leave you and your family in harbors way and living without food, water and other necessities of life. That is why it is important to make sure that you have an emergency kit prepared so that you are able to weather the storm, so to speak. Here are some things that should be considered when building or purchasing an emergency kit so that you can be prepared for anything that might occur.

One of the most important things for you to consider when building an emergency kit are the basic necessities. You are going to need to have food and water available because without food and water, you could quickly get sick or may even end up losing your life. Although the amount of food and water that you need may vary, depending upon the kit that you are building, it is generally recommended that you have at least three days supply available. For water, you should have a gallon for every day and for every individual that is going to be using what is available in the emergency kit. The type of food should be nonperishable as you will want to be able to store it for a long time and you certainly may not have refrigeration available during that time.

First aid may be necessary during an emergency so it is important for you to have the first aid supplies that are needed in the kit as well. Of course, this is going to different, depending upon your specific needs and the type of problems that may exist. At the very least, you should have a first aid kit available, although it is never a bad idea for you to build on that specific supply.

A flashlight is an essential part of any home emergency kit but you should make sure you also have extra batteries available. If possible, have a few flashlights available for an emergency. You should also have a hand crank radio or a battery-powered radio so that you can listen to NOAA weather alerts and get any other information that you may need during the time of an emergency.

It may be necessary for you to signal for help in an emergency so you should include a whistle in the emergency kit. Make sure that it is loud enough to be heard over a long distance.

There are also many other small items that should be included in an emergency preparedness kit. These include garbage bags, moist towelettes and other supplies that will be used for personal sanitation purposes. If you have any food in a can, make sure that you have a manual can opener available. Local maps may be necessary and you should have a cell phone for emergency purposes, including a solar charger or inverter so that you do not need to rely on the local power system to charge the cell phone, in case it should be down. Although it is impossible for you to plan for all emergencies, being as prepared as possible can make a difference in the survival of you and your family.


How to Pack a 72 Hour Emergency Kit

Pictures of families lined up for water after the recent Haiti earthquake prompted many Americans to organize emergency supplies, but with the plethora of information available it can be confusing to determine what should actually go into an emergency survival kit. The reason it is so confusing is that you actually need to address two emergency situations: if you're stranded at home, or if you have to evacuate. Essentially, you need to prepare two kits, the at-home kit and the go kit. Use this list to get you started.

What should go in an emergency survival kit?

A proper emergency survival kit (at home or go) should address the following needs:

· Water
· Food
· Warmth
· Shelter
· Light
· Communication
· First aid


The recommended guideline is one gallon of water per person per day for your at-home kit. Consider using commercially packaged water (including the kind that is good for 5 years) or water storage barrels. For your go kit, pack your emergency kit with any combination of the following: water pouches, water purification tablets, water filters or emergency water straws. A good guideline is to have at least 1 liter of water per person for drinking and plan to obtain the rest through use of your tablets, filters or straws.


For your at-home kit, you have more space, so you can pack food stuff that can be eaten cold, are self-heating or can be heated / cooked over a camp stove. MRE's, camping food, canned foods are all good choices. Make sure to pack a manual can opener and / or camp stove. For your go kit, you will need lighter food stuffs, so try packing 72 hours of MREs, energy bars, self-heating meals, or meals that just need water. These tend to be made out of dehydrated food stuffs, so are lighter and easier to carry.


If you're stuck at home without power or gas, it might get awfully cold. Add blankets or sleeping bags to your at-home kit to combat the chills. For your go kit, purchase a space blanket or emergency survival sleeping bag: they are tiny and compact, yet still will keep the chill away.


If you are stranded at home, your shelter needs are met. If you have to evacuate however and for whatever reason can not stay in a hotel / motel, car, or emergency Shelter, pack a tent in your go kit. You can use a regular camping tent if it fits in your go kit, or look into tube tents: a 2 person rope and tarp system. These fold up extra small, space savers for your go kit.


Nothing is as irritating as having the power go out in your house. Check your supply of flashlights and batteries to make sure they are still good and to determine if you need more. Camping lanterns can also be kept in your at-home kit. For your go kit, there are many rechargeable options, such as crank flashlights or solar flashlights. These are small and eliminate the need for batteries.


It never fails, during any disaster big or small we are all glued to the news, just waiting to see what happens next. Pack a radio in your at-home and go kits so you can hear the latest, including important information such as road or bridge closures and locations of nearest Shelters. A good choice are the radios that are crank powered and receive NOAA weather stations.

First Aid

Knowing that you will have to wait for emergency responders to arrive, empower yourself and your family by packing first aid kits in your at-home and go kits and by taking first aid classes. This way you can offer comfort and aid to yourself and your neighbors.

How should it be packaged?

Your at-home kit can be packed in plastic tubs, the ones with rollers are especially handy. Place the tub in an accessible location in your house, consider a ground floor location in case you can not manage stairs. Your go kit should be packed in a backpack and stored near your emergency exits (doors or windows). Practice walking around with your backpack go kit to make sure it is manageable for you and not too heavy.

Where do I get supplies?

Emergency supplies are just an internet search away. You can buy each item separately, or look into purchasing ready-made go kits . By buying in a package, you can often get a deal. Your local outdoor store is also a great resource for buying compact-sized items.
