Abstract

A head wearable device includes a headpiece, a housing attached to the headpiece, a luminaire attached to the headpiece, the luminaire including a luminaire housing and at least one light source located within the luminaire housing, a duct system connecting the luminaire to the housing, a ball joint rotatably connecting the duct system to the luminaire, and an air moving device configured to induce a cooling air flow through an inlet in the luminaire housing, through the heatsink, through the ball joint, through the duct system, and out of an exhaust in the housing attached to of the headpiece.

First claim

The invention claimed is:

1. A head wearable device comprising:
a headpiece comprising:
a headband comprising a top strap and at least two lateral straps;
an occipital basket comprising a strap, the occipital basket being attached to the headband by at least one lateral extension strap pivotably attached by a hinge to a distal end of each respective lateral strap of the headband;

a first housing attached to an outer surface of the top strap of the headband;
a depth adjuster attached to the first housing, the depth adjuster comprising a first gear rotatably fixed to a first knob;
wherein the strap of the occipital basket comprises a slot with a plurality of teeth formed around a longitudinal edge of the slot;
wherein the first gear is captively held within the slot and engages with the plurality of teeth;
wherein the depth adjuster is configured such that a rotary movement of the first gear causes a longitudinal movement of the strap of the occipital basket to change a distance between the occipital basket and the first housing;
wherein a depth of the headpiece changes when the distance between the occipital basket and the first housing changes; and
wherein the strap comprises a first visual index comprising a first plurality of sequential characters, each of which correspond to one of a plurality of predetermined depth settings of the headpiece; and

a second housing attached to an outer surface of the occipital basket;
a headband adjuster at an outer surface of the occipital basket, the headband adjuster comprising a second gear rotatably fixed to a second knob;
wherein the lateral extension straps each comprise a slot with a plurality of teeth formed around a longitudinal edge of the slot;
wherein the second gear is captively held within the slot of each lateral extension strap and engages with the plurality of teeth of each of the lateral extension straps;
wherein the headband adjuster is configured such that a rotary movement of the second gear causes a longitudinal movement of the lateral extension straps to change a circumference of the headpiece; and
wherein at least one of the lateral extension straps comprises a second visual index comprising a second plurality of sequential characters, each of which correspond to one of a plurality of predetermined circumferential settings of the headpiece;

wherein the head wearable device is configured such that the lateral extension straps rotate about the hinge, relative to the lateral straps as the depth of the headpiece changes.

2. The head wearable device of claim 1 , wherein the first and second visual indexes comprise alphanumeric characters.

3. The head wearable device of claim 2 , wherein the first visual index and the second visual index comprise different ranges and/or types of alphanumeric characters.

4. The head wearable device of claim 3 , wherein the first visual index comprises a plurality of sequential letters and the second visual index comprises a plurality of sequential numbers.

5. The head wearable device of claim 3 , wherein the first visual index comprises a plurality of sequential numbers and the second visual index comprises a plurality of sequential letters.

6. The head wearable device of claim 1 , comprising padding on an inner surface of the headband and the occipital basket.

7. The head wearable device of claim 6 , wherein a notch is in a lower edge of the occipital basket and configured to prevent a wearer's hair or cap from interfering with proper fitment of the headpiece about a head of a wearer.

8. The head wearable device of claim 7 , wherein the padding on the occipital basket comprises a recessed area configured to prevent the wearer's hair or cap from interfering with proper fitment of the headpiece about the head of the wearer.

9. The head wearable device of claim 6 , wherein the padding is removably attached to the headband and the occipital basket.

10. The head wearable device of claim 6 , wherein the padding is configured to be positioned spaced on a head of a wearer of the head wearable device without covering or being positioned over a suture between adjacent plates of a skull of the wearer of the head wearable device.

11. A method of adjusting a size of a headpiece of a head wearable device to a head size of a wearer, the headpiece comprising a headband and an occipital basket, the method comprising:
attaching a first housing to an external surface of a top strap of the headband;
inserting a strap of the occipital basket at least partially into the first housing;
engaging a first gear with a plurality of teeth formed in a slot, which is longitudinally oriented along a length of the strap of the occipital basket;
turning a first knob, which is rotationally locked to the first gear, to adjust a depth of the headpiece;
attaching a second housing to an external surface of the occipital basket;
inserting an end of at least two lateral extension straps into the second housing, with the end of a first lateral extension strap being inserted from an opposite end of the housing from the end of a second lateral extension strap, wherein the two lateral extension straps are hingedly attached to lateral straps of the headband to define a circumference of the headpiece;
engaging a second gear with a plurality of teeth formed in a slot of each of the lateral extension straps such that the second gear is engaged with both of the lateral extension straps; and
turning a second knob, which is rotationally locked to the second gear, to adjust a circumference of the headpiece.

12. The method of claim 11 , comprising:
providing a first visual index along a length of the strap of the occipital basket, the first visual index comprising sequential alphanumeric characters to designate predetermined depth settings for the headpiece;
providing a second visual index along a length of at least one of the lateral extension straps, the second visual index comprising sequential alphanumeric characters to designate predetermined circumference settings for the headpiece;
determining a wearer preference for the depth and circumference of the headpiece corresponding to the first and second visual indexes;
placing the head wearable device on the wearer's head;
adjusting the first knob such that the first visual index indicates that the wearer preference for the depth of the headpiece has been achieved; and
adjusting the second knob such that the second visual index indicates that the wearer preference for the circumference of the headpiece has been achieved.

13. The method of claim 12 , wherein the first visual index and the second visual index comprise different ranges and/or types of alphanumeric characters.

14. The method of claim 13 , wherein the first visual index comprises a plurality of sequential letters, the second visual index comprises a plurality of sequential numbers, and the wearer preference is designated by one of the plurality of sequential letters and one of the plurality of sequential numbers.

15. The method of claim 13 , wherein the first visual index comprises a plurality of sequential numbers and the second visual index comprises a plurality of sequential letters.

16. The method of claim 11 , comprising attaching padding on an inner surface of the headband and the occipital basket.

17. The method of claim 16 , comprising forming a notch into a lower edge of the occipital basket to prevent a wearer's hair or cap from interfering with proper fitment of the headpiece about a head of a wearer.

18. The method of claim 17 , comprising forming a recessed a
