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 attached to 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;
wherein the depth adjuster is configured to change a distance between the occipital basket and the first housing; and
wherein a depth of the headpiece changes when the distance between the occipital basket and the first housing changes; and

a second housing attached to an outer surface of the occipital basket; and
a headband adjuster attached to the occipital basket, wherein the headband adjuster is configured to change a circumference of the headpiece.

2. The head wearable device of claim 1 , comprising, on at least a first portion of the occipital basket, a first visual index comprising a first plurality of characters, each of which correspond to one of a plurality of predetermined depth settings of the headpiece, and, on at least a second portion of the occipital basket, a second visual index comprising a second plurality of characters, each of which correspond to one of a plurality of predetermined circumferential settings of the headpiece, 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 formed in a lower edge of the occipital basket, the notch being configured to prevent hair or a cap of a wearer from interfering with proper fitment of the headpiece about a head of the wearer.

8. The head wearable device of claim 7 , wherein the padding on the occipital basket comprises a recessed area configured to prevent the hair or cap of the wearer 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/or the occipital basket.

10. The head wearable device of claim 6 , wherein the padding is configured to be positioned spaced about and/or over 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 a top strap of the headband;
inserting a first portion of the occipital basket at least partially into the first housing;
adjusting a depth of the headpiece to correspond to the head size of the wearer;
attaching a second housing to the occipital basket;
inserting at least a second portion of the occipital basket into the second housing to define a circumference of the headpiece; and
adjusting the circumference of the headpiece.

12. The method of claim 11 , comprising:
providing a first visual index along a length of the first portion of the occipital basket, the first visual index comprising alphanumeric characters to designate predetermined depth settings for the headpiece;
providing a second visual index along a length of the second portion of the occipital basket, the second visual index comprising alphanumeric characters to designate predetermined circumference settings for the headpiece;
determining a wearer preference for the depth and/or the circumference of the headpiece corresponding to the first and second visual indexes;
placing the head wearable device on the wearer's head;
adjusting the depth of the headpiece such that the first visual index indicates that the wearer preference for the depth of the headpiece has been achieved; and/or
adjusting the circumference of the headpiece 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 for the depth and the circumference of the headpiece is designated by one of the plurality of sequential letters and one of the plurality of sequential numbers, respectively.

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 in a lower edge of the occipital basket to prevent hair or a cap of the wearer from interfering with proper fitment of the headpiece about a head of the wearer.

18. The method of claim 17 , comprising forming a recessed area in the padding on the occipital basket to prevent the hair or cap of the wearer from interfering with proper fitment of the headpiece about the head of the wearer.

19. The method of claim 16 , wherein the padding is removably attached to the headband and/or the occipital basket.

20. The method of claim 16 , comprising positioning the padding such that the padding can be positioned about and/or over a head of the 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.
