This is the "horizontal gaze nystagmus" test, a relatively recent development in DUI investigation. The officer attempts to estimate the angle at which the eye begins to jerk ("nystagmus" is medical jargon for a distinctive eye oscillation); if this occurs sooner than 45 degrees, it theoretically indicates a blood-alcohol concentration over .05%.

Police use these Field Sobriety tests against you in court to show that you were impaired to drive. They don't tell you that these tests are voluntary and that you do not have to take them. Of the three field tests, only the Horizontal Gaze Nystagmus (HGN) has been deemed scientific in Georgia. The theory behind the HGN is that a person who is impaired due to alcohol will have his/her eyes jerk (nystagmus) at certain points while following a pen or finger.

This is the horizontal gaze nystagmus (HGN) test. When conducting this test, the officer is watching for an involuntary jerking of the eye, which may, among other causes, by caused by consumption of alcohol. If the officer detects three clues in each eye, lack of smooth pursuit, nystagmus at maximum deviation, and nystagmus prior to 45 degrees, then he is trained to arrest.

The left and right ankle are anatomically different. Therefore, they require differently shaped supports for optimal fit and therapy. MalleoTrain also has 2 silicone inserts that are shaped differently to accommodate the inside and outside of the ankle bones. The silicone on the inside is thicker and shorter to fill in the more concave area on this side of the ankle bone.

The aim of all Ultralase vision correction is to improve your eyesight. Everything we do is targeted to achieve that, from the equipment we install to the recruitment of highly-skilled specialists, from the procedures we follow to the assessments we make. In a minority of cases, there is need for retreatment. Read the safety and risks section for more detail. Recent evidence suggests that stability of outcome is excellent for ten or more years post-treatment.

Yes, for vehicles that were designed to have them and in certain exotic applications. For example, some vehicles such as Toyota 4x4 trucks and 4Runners have front springs with different arches and heights on the left and right. Yet some spring companies make identical front springs and expect you to use a block or shim plate to make the truck sit level. However, in all such left/right cases, Alcan Spring makes the correct left and right springs without ever relying on blocks or spacers.

Over the years, I have made adaptive instruments thay people did not believe possible. Look here. So there is a very good chance that I can help you.

Yes, this is a type of FST. If you have a penlight moved in front of your face and the police officer asks you to follow it with your eyes, this is the "horizontal gaze nystagmus" test. With it the police officer is attempting to estimate the angle at which the eye begins to jerk ("nystagmus" is medical jargon for eye jerking); if the eyes jerk sooner than 45 degrees, it theoretically indicates an excessive blood-alcohol concentration.

This ain't a political blog... and both Sue and myself don't toe any party lines... we do vote, but we vote on issues and the abilities of our local representative... we're neither left nor right... not even really centre... we simply look at the issues and work from what we believe works and what doesn't... and there's good points to BOTH sides.

There is no pan control on the unit so this can only be accomplished with a semi-permanent modification. Removing the appropriate 4.02k ohm resistor from the board will prevent the signal from appearing on that bus output. (example: Removing R51 prevents the channel 1 signal from appearing on the left output connector.) The MLM 82a addresses this through the use of assign switches.
