Abstract

A modular flashlight and a modular flashlight system are provided. In one example, the modular flashlight includes a base configuration that can be modified with a modular extension unit.

Claims

1. A flashlight system, comprising:

a housing with a first end and a second end;

a retention device configured to interface with and contain the housing;

a light source disposed at a first end of the housing;

a controller configured to toggle an output mode of the light source between at least an on state and an off state;

a first switch electrically coupled to the controller, configured to provide an input signal to the controller to toggle the light source between at least the on state and the off state; and

a sensor electrically coupled to the controller, wherein the sensor is configured to detect a presence of a component matched to the sensor by detection of a magnetic field of the component, the component positioned in the retention device such that the sensor does not contact the component, and wherein the sensor is configured to provide an input signal to the controller to store an operating on/off state into memory upon detection of a component matched to the sensor being in proximity to the sensor, and

upon removal of the housing from the retention device resulting in the component matched to the sensor being moved out of proximity to the sensor, the controller returning the light source to the stored operating on/off state.

2. The flashlight system of claim 1 wherein a retention device is configured to removably receive the housing so that the sensor is positioned proximate to the component matched to the sensor when the housing is received into the retention device.

3. The flashlight system of claim 2 wherein a tail cap is configured to removably couple to the second end of the housing, wherein a second switch is configured to toggle the light source between at least an on state and an off.

4. The flashlight system of claim 1 wherein the controller is additionally configured to toggle the light source to a user-defined on/off state and output mode upon removal of the component matched to the sensor.

5. The flashlight system of claim 1 wherein a tail cap is configured to removably couple to the second end of the housing, wherein a second switch is configured to toggle the light source between at least an on state and an off.

6. A retention device operable to interact with a flashlight having a sensor, comprising:

a receptacle for receiving the flashlight, the receptacle having a lip to prevent the flashlight from sliding through; and

a component matched to the sensor, for interacting with the sensor of the flashlight,

wherein the component matched to the sensor provides a magnetic field detectable by the sensor, such that the sensor can control at least one of an on state and an off state of a light source of the flashlight when in proximity to the retention device,

wherein the component matched to the sensor is positioned in the retention device such that the sensor does not contact the component matched to the sensor, and

wherein the sensor is configured to provide an input signal to store an operating on/off state into memory upon detection of a component matched to the sensor in proximity to the sensor, and, upon removal of the flashlight from the retention device resulting in the component matched to the sensor being moved out of proximity to the sensor, return the flashlight to the stored operating on/off state.

7. A retention device comprising:

a receptacle for receiving a flashlight, the flashlight including a sensor;

an electric current delivery system to charge a flashlight battery within the retention device;

a power receptacle for receiving power from a power source external to the retention device;

a component matched to the sensor, for interacting with the sensor of the flashlight, wherein the component matched to the sensor provides a magnetic field detectable by the sensor, such that the sensor can control at least one of an on state and an off state of a light source of the flashlight when in proximity to the retention device, wherein the component matched to the sensor is positioned in the retention device such that the sensor does not contact the component matched to the sensor, and wherein the sensor is configured to provide an input signal to store an operating on/off state into memory upon detection of a component matched to the sensor in proximity to the sensor, and, upon removal of the flashlight from the retention device resulting in the component matched to the sensor being moved out of proximity to the sensor, return the flashlight to the stored operating on/off state; and

a visual indicator for displaying a charging status of the flashlight battery.

8. The retention device of claim 7 further comprising:

a charging circuit board.

9. The retention device of claim 8 further comprising a female power output receptacle in a common Universal Serial Bus (USB) arrangement coupled to an internal battery.

10. A modular flashlight system, comprising:

a first housing with a first end and a second end;

a retention device configured to interface with and contain the first housing;

a light source disposed at the first end of the first housing;

a controller configured to toggle the light source between at least an on state and an off state; and

a first switch electrically coupled to the controller, configured to provide an input signal to the controller to toggle the light source between at least the on state and the off state;

a sensor electrically coupled to the controller, wherein the sensor is configured to;

detect a presence of a component matched to the sensor by detection of a magnetic field of the component, the component positioned in the retention device such that the sensor does not contact the component, and wherein the sensor is configured to provide an input signal to the controller to store an operating on/off state into memory upon detection of a component matched to the sensor being in proximity to the sensor, and

upon removal of the first housing from the retention device resulting in the component matched to the sensor being moved out of proximity to the sensor, the controller returning the light source to the stored operating on/off state; and

a modular extension unit having a second housing with a third end and a fourth end, wherein the third end is configured to removably couple to the second end of the first housing, wherein the second housing is configured to complete the circuit to provide power to the light source, wherein only one of a tail cap and the second housing can be coupled to the second end at a particular time.

11. A modular flashlight system, comprising:

a first housing with a first end and a second end;

a retention device configured to interface with and contain the first housing;

a first light source disposed at the first end of the first housing;

a second housing removably coupled to the first housing, and having a second light source;

a controller configured to toggle at least one of the first light source and the second light source between at least one of an on state and an off state;

a sensor electrically coupled to the controller, wherein the sensor is configured to;

detect a presence of a component matched to the sensor by detection of a magnetic field of the component, the component positioned in the retention device such that the sensor does not contact the component, and wherein the sensor is configured to provide an input signal to the controller to store an operating on/off state into memory upon detection of a component matched to the sensor being in proximity to the sensor, and

upon removal of the first housing from the retention device resulting in the component matched to the sensor being moved out of proximity to the sensor, the controller returning the at least one of the first light source and the second light source to the stored operating on/off state;

a first switch electrically coupled to the controller, configured to provide an input signal to the controller to toggle at least one of the first light source and the second light source between at least one of the on state and the off state; and

a second switch configured to toggle at least one of the first light source and the second light source between at least one of the on state and the off state independently of the first switch.
