So your Areas of Focus should include both your strengths AND your weaknesses. However, we all have a tendency to focus on certain areas at the expense of other areas. The key is to determine the areas that are most important to you. How to Select Your Wheel of Life Categories Or anything else that might play a dominant role in your life. These are the basic categories of most people’s Wheel of Life.Īdditional Wheel of Life categories might include: Spirituality: This can be its own category or simply the driving force behind all of your Areas of Focus. Personal Growth: Although not everyone might have an Area of Focus for personal development, anyone interested in Self-Actualization does. Professional/Business: This is your work category, which can break out into a Wheel of Business. Social: Includes religious/spiritual communities and other group activities.įinancial: Your ability to manage your money effectively, save, budget, and invest. Relationships: Includes your primary intimate relationship, family, and friends. Health: Your physical health and well-being (can also include your emotional health). Drucker’s Big Three for the Wheel of BusinessĪlthough the name you give these Wheel of Life categories may vary, these areas themselves are generally the same for each of us.Before Your Start the Wheel of Life Exercise.Assess Your Current Level of Fulfillment.How to Select Your Wheel of Life Categories.(This diagram also shows the Hummer's run-flat feature, which allows the tire to continue supporting the vehicle even when it will not hold any air. The "quick disconnect fitting" allows the tire to be separated from the CTIS system for removal or servicing. The tubing runs from the vehicle's air compressor through the wheel hub and then to the tire valve. In this illustration, you can see the pathway that the air travels for inflation or deflation once it gets to the wheel. When the pneumatic control unit reads that the appropriate pressure is reached, the valve closes. If the tires are overinflated, the system applies a slight vacuum to the wheel valve. If the system determines that inflation is needed, it first checks to make sure that brake pressure reserves are where they should be if they are, it applies a slight pressure to the wheel valve to allow inflation. Here is what happens on the road: The electronic control unit tells the pneumatic control unit to check current pressure and either inflate or deflate the tire to the pressure selected by the driver. Hummer self-inflating tire system: At the wheel A pressure switch makes sure the brake system gets priority, preventing the CTIS from taking air from the supply tank until the brake system is fully charged. This type of system uses air from the same compressor that supplies air to the brakes. If the vehicle continues moving at a higher speed for a set period of time, the system automatically inflates the tires to an appropriate pressure for that speed. The CTIS includes a speed sensor that sends vehicle speed information to the electronic control unit. When vehicles are moving faster (like on a highway), tire pressure should be higher to prevent tire damage. When the driver selects a tire-pressure setting, signals from the control panel travel to the electronic control unit to the pneumatic control unit to the wheel valves. This dash-mounted panel displays current tire pressures, selected modes and system status. The pneumatic control unit also contains a sensor that transmits tire-pressure readings to the ECU.Īn operator control panel allows the driver to select tire-pressure modes to match current conditions. The ECU sends commands to the pneumatic control unit, which directly controls the wheel valves and air system. It processes driver commands, monitors all signals throughout the system and tells the system to check tire pressures every 10 minutes to make sure the selected pressure is being maintained. The wheel valve also enables on-demand inflation and deflation of the tires.Īn electronic control unit (ECU) mounted behind the passenger seat is the brain of the system. Part of the wheel valve's job is to isolate the tire from the system when it's not in use in order to let the pressure off of the seal and extend its life. For dual wheels, the valves are typically connected only to the outer wheel so the pressure between the two tires can be balanced. CTIS: InsideĪ wheel valve is located at each wheel end. Dana Corporation has two versions, the CTIS for military use (developed by PSI) and the Tire Pressure Control System (TPCS) for commercial, heavy machinery use. There are two main manufacturers of the CTIS: U.S.-based Dana Corporation and France-based Syegon (a division of GIAT).
