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.

First claim

What is claimed is:

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.
