The FDA requires all sunglass lenses to be impact-resistant. If you play sports or wear sunglasses on the job, you might want to consider ultra-impact-resistant polycarbonate lenses for even greater eye safety.

How do I fix/reset code B0041


DTC B0041 will set when one of the following conditions occurs:
- The SDM detects the LF side impact module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.
- The SDM detects the voltage at LF side impact module high control is less than 2.4 volts and LF side impact module deployment loop resistance is 6 ohms or greater for 500 milliseconds. it will continue to reset till the fault is repaired.

2000 CHEVY IMPALA AIR BAG LIGHT ON


  • B0041
CIRCUIT DESCRIPTION
The inflatable restraint side impact module-LF deployment loop consists of the inflatable restraint side impact module-LF, the inflatable restraint side impact module wiring harness, and the side impact module-LF high and low circuits. A shorting bar used within the side impact module-LF connector shorts together the side impact module-LF high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) allows current to flow through the deployment loop in order to deploy the side impact module-LF. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.

CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.

CONDITIONS FOR SETTING THE DTC
  • DTC B0040 will set when the side impact module-LF deployment loop resistance is less than 1.3 ohms for 500 milliseconds .
  • DTC B0041 will set when one of the following conditions occurs:
  • Side impact module-LF high circuit is less than 2.4 volts and the side impact module-LF deployment loop is more than 6 ohms for 500 milliseconds .
  • Side impact module-LF deployment loop resistance is more than 4.8 ohms for 500 milliseconds .
  • DTC B0045 will set when one of the following conditions occur:
  • Side impact module-LF high and/or low circuits is short to ground or short to voltage for 500 milliseconds .
  • Side impact module-LF high circuit is less than 2.4 volts and side impact module-LF deployment loop resistance is less than 6 ohms for 500 milliseconds .
ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON via Class 2 serial data.

CONDITIONS FOR CLEARING THE DTC
  • The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
  • A history DTC will clear once 255 malfunction free ignition cycles have occurred.
DIAGNOSTIC AIDS
The following are possible causes of the malfunction:
  • A short between the side impact module-LF high and low circuits
  • An open or a high resistance in the side impact module-LF high or low circuits
  • A short to ground or a short to voltage in the side impact module-LF high or low circuits
  • The side impact module-LF connector
  • The SDM connector
  • A malfunctioning side impact module-LF
  • A malfunctioning SDM

How does stab- and puncture-resistant body armour work?


Stab- and puncture-resistant armours are made from a variety of materials. The most commonly used materials are made from extremely strong fibres, which can be either woven or laminated together. Other materials used are metals and composites. As the threat impacts the armour, the materials either deflect the threat or, due to their very high level of cut and/or tear resistance, they "stretch" and the impact forces are dissipated over a larger area of the armour.

Should I purchase a sunglasses with a glass lens?


Well, here are some facts about glass lenses that might help you reach a better decision.Glass is the only lens material that can be made into 100% optically correct sunglasses. For true vision, there is no comparison between glass and other lens materials.
Glass does not flex or compress. Whenever lenses are placed into an eyewear frame, they are held in place by pressure of some kind. Plastic lenses flex and that creates distortion; but that cannot happen with glass lenses.
Glass does not expand or contract in heat and cold in a significant way. No matter what the temperature outside, 100% optically correct sunglasses will remain 100% optically correct.
Glass is the hardest material, and the most scratch-resistant. Glass is the most durable, and longest-lasting sunglass lens material. However, it is not scratch proof. Sand can scratch glass, but it requires serious effort or trauma to scratch glass lenses.
Technology has made it possible to create a very lightweight glass lens. Today, it can be difficult to tell the difference between glass and plastic, even when holding a pair with glass lenses in one hand and a pair with plastic in the other hand. (Of course, the difference is clear when looking through the lenses. But the weight of the lens is no longer a dead giveaway as to which is which.)

The danger of shattering was once one of the major disadvantages of glass lenses. However, all glass lenses pass the "Drop Ball Test" for impact resistance - the same test that is administered to polycarbonate and CR-39 lenses. When today's polarized lenses tend to break in a similar pattern as a car windshield. The broken pieces of glass mostly stick to the polarizing film that is inside the lens.
These Spotters had been stepped on by the customer. Notice that the broken lens has retained its original curvature. The broken lens pieces were still so tightly held by the frame that we had to smash the broken lens out of the frame with a hammer (it took more than a few smacks, too!). This isn't to say in any way that glass lenses are equivalent to safety glasses. However, polarized glass lenses are much, much less likely to cause injuries today than they ever have been in the past.

What is so unique about Polycarbonate Lenses?


Polycarbonate lenses are the most-used alternative material for modern ophthalmic lenses. Consumer interest in thinner, more attractive spectacle lenses led to the development of special lens materials that would bend light differently than conventional plastic lenses. These materials are called "hi-index".
Among the high index materials developed for eyeglasses is one material that has a number of very unique properties and that also provides special benefits to eyeglass wearers. It carries the generic name "polycarbonate" but is sometimes called something different by other manufacturer trade names.
Great for sports protective eyewear
A "must" for kids
Comes with FREE Scratch and UV Protection
Impact Resistant - Polycarbonate Surpass AR lenses are 10 times more impact resistant than plastic lenses.
Lighter - Polycarbonate Surpass AR lenses are up to 35% lighter and thinner than standard plastic lenses for greater comfort.
UV Protection - Polycarbonate Surpass AR lenses shield your eyes from virtually 100% of the sun's harmful UV rays.
Scratch Resistant - PolyCarbonate Surpass AR lenses are hardcoated for excellent durability and scratch resistance.
Easy Care - PENTAX EasyClean™ treatment resists dust and smudges, making your Polycarbonate Surpass AR lenses easy to clean.
Polycarbonate was the first plastic high index lens and still has one of the highest index ratings (1.59). High index advantages are included with every polycarbonate lens so there is never any extra charge for high index when polycarbonate lenses are ordered. Originally used primarily for industrial safety glasses, now used for children, sports wearers, or anyone requesting greater impact resistance in their lenses.

Camera lense stuck in


Gear box problem ( not so expensive to repair ) or lens impacted ( this type of problem can be sorted out only by replacing the entire lens unit and is often uneconomical ).
