Abstract

A wireless headlight assembly for attachment to an eyewear frame is disclosed. The wireless headlight assembly comprises a battery pod containing a battery connected to a lower housing element, which controls the application of power from the battery to an attached headlight assembly containing a headlight.

Claims

1. A magnification eyeglass system comprising:

a frame comprising;

a pair of lenses joined by a bridge portion;

a telescopic lens incorporated within a corresponding one of said lenses; and

a pair of temples configured to extend substantially perpendicular to said lenses;

a headlight assembly removably attached to the bridge portion, said headlight assembly comprising;

a housing having incorporated therein at least one lighting element, and

a battery assembly comprising;

a lower assembly comprising;

a sensing element comprising;

 

a translucent window, said sensing element configured to;

 

transmit an infra-red (IR) signal through said translucent window; and

 

detect a reflection of the transmitted IR signal through said translucent window; and

an electronic system configured to;

 

receive an indication of the detected reflection of the transmitted IR signal; and

control an application of a voltage to the at least one lighting element based on the received indication;

a battery pod attached to the lower assembly, said battery pod containing a battery element therein, said battery providing said voltage to the at least one light element through the electronic system.

2. The magnification eyeglass system of claim 1, wherein a positive terminal of the battery element is configured to electrically contact a positive contact of electronic system and a negative terminal of the battery element is configured to electrically contact a negative contact, of the electronic system.

3. The magnification eyeglass system of claim 1, wherein the housing is pivotally attached to the lower assembly.

4. The magnification eyeglass system of claim 1, wherein the at least one lighting element comprises at least one light emitting diode.

5. The magnification eyeglass system of claim 4, wherein the at least one light emitting diode is arranged in an array.

6. The magnification eyeglass system of claim 1, wherein the control of an application of a voltage to the at least one lighting element comprises one of:

removing the voltage from the at least one lighting element and applying the voltage to the at least one lighting element.

7. The magnification eyeglass system of claim 1, wherein the control of an application of a voltage varies an intensity of light output of the at least one lighting element.

8. The magnification eyeglass system of claim 1, wherein the battery pod is attached to the lower assembly through one of:

a screw thread connection, a bayonet connection, a quarter-turn locking connection, and a snap-in connection.

9. A head mounted magnification system comprising:

a frame

a headlight assembly removably attached to the frame, said headlight assembly comprising;

a housing having incorporated therein at least one lighting element, and

a battery assembly, pivotally attached to the housing, comprising;

a battery pod containing a battery therein, the battery configured to output a voltage; and

a lower assembly, wherein the battery is connected to the lower assembly, the lower assembly comprising;

means for;

 

retaining the battery pod; and

 

receiving the battery voltage;

a sensing element configured to;

 

transmit an infra-red (IR) signal, wherein the lower assembly comprises a translucent window though which said IR signal is transmitted; and

 

detect a reflection of the transmitted IR signal; and

an electronic system configured to;

 

receive an indication of the detected reflection of the transmitted IR signal; and

 

control an application of the battery voltage to the at least one lighting element based on the received indication.

10. The head mounted magnification system of claim 9, further comprising:

a plurality of lens attached to the frame; and

a magnification lens in each of the lenses.

11. The head mounted magnification system of claim 10, wherein the battery comprises:

a positive terminal; and

a negative terminal on a single surface of the battery; and

said lower assembly includes a positive contact and a negative contact, the positive contact configured to contact the positive terminal and the negative contact configured to contact the negative terminal.
