Abstract

Support structures for positioning sensors on a physiologic tunnel for measuring physical, chemical and biological parameters of the body and to produce an action according to the measured value of the parameters. The support structure includes a sensor fitted on the support structures using a special geometry for acquiring continuous and undisturbed data on the physiology of the body. Signals are transmitted to a remote station by wireless transmission such as by electromagnetic waves, radio waves, infrared, sound and the like or by being reported locally by audio or visual transmission. The physical and chemical parameters include brain function, metabolic function, hydrodynamic function, hydration status, levels of chemical compounds in the blood, and the like. The support structure includes patches, clips, eyeglasses, head mounted gear and the like, containing passive or active sensors positioned at the end of the tunnel with sensing systems positioned on and accessing a physiologic tunnel.

Claims

1. A contactless detector comprising:

a brain tunnel radiation energy probe sized to fit between an eyebrow and an eye of an individual for remotely receiving radiation energy from the skin at a brain tunnel, said brain tunnel being located between the eyebrow and the eye of the individual, said probe including a column for receiving radiation energy, said column including a distal end and a proximal end,

a brain tunnel temperature sensor located at said proximal end of said column,

said distal end of said column being a window directly receiving all of the radiation energy from the brain tunnel at the distal end of said column and transferring the radiation energy from the brain tunnel to the brain tunnel temperature sensor located at the proximal end of the column, along an unobstructed path,

said radiation energy being transmitted to said brain tunnel temperature sensor located at the opposite end of the column in the absence of obstructions to avoid reducing an intensity of the radiation energy,

said column having a constant cross section with a largest cross section of less than 3.0 mm,

a ratio of a length of said column to the constant cross section of said column being at least 10;

1, and

an ambient temperature sensor mounted on an exterior of the brain tunnel radiation probe, said ambient temperature sensor measuring ambient temperature to adjust temperature measured by said brain tunnel temperature sensor.

2. The contactless detector as claimed in claim 1, wherein the length of said column is about 3 cm.

3. The contactless detector as claimed in claim 1, further comprising a separation distance detecting arrangement included with the probe for maintaining a separation distance between the radiation energy probe and the skin at the brain tunnel.
