Abstract

An addressing device and method for addressing an addressed device configured to be removeably engaged with the addressing device. The addressing device includes a series of addressing device contacts that are individually and selectively configured to move from a first contact position to a second non-contact position via a respective switch. In the first contact position, an addressing device contact forms an electrical connection with a respective addressed device contact when the addressing device and the addressed device are in the engaged position. In the second non-contact position the addressing device contact does not form an electrical connection with a respective contact of the addressed device. The sequence of continuity provided to the addressed device by the selective contact or non-contact of the addressing device contacts is used to set an address of the addressed device.

Claims

1. An addressing device, comprising:

a mounting base configured to be removably engaged with a corresponding mounting portion of an addressed device, wherein being removably engaged includes being moveable from a non-engaged position to an engaged position;

a constant contact configured to contact a respective addressed device constant contact when the addressing device and the addressed device are in the engaged position;

a first contact that is electrically connected to the constant contact;

a first switch configured to move the first contact from a first position to a second position, wherein in the first position the first contact forms an electrical connection with a first addressed device contact when the addressing device and the addressed device are in the engaged position, and wherein in the second position the first contact forms an open electrical connection with the first addressed device contact when the addressing device and the addressed device are in the engaged position;

a second contact that is electrically connected to the constant contact and the first contact; and

a second switch configured to move the second contact from a third position to a fourth position, wherein in the third position the second contact forms an electrical connection with a second addressed device contact when the addressing device and the addressed device are in the engaged position, and wherein in the fourth position the second contact forms an open electrical connection with the second addressed device contact when the addressing device and the addressed device are in the engaged position.

2. The addressing device of claim 1, wherein an address of the addressed device is set by the addressing device when the addressing device and the addressed device are in the engaged position.

3. The addressing device of claim 1, wherein the addressed device comprises a sensor and the addressing device is a mount for the addressed device.

4. The addressing device of claim 1, wherein the first contact and the second contact are biasing members respectively capable of contacting a corresponding one of the first addressed device contact and the second addressed device contact.

5. The addressing device of claim 4, wherein the first switch is rotatable about a first axis and comprises a first portion and a second portion that extends further from the first axis than the first portion, wherein when the first switch is moved from the first position to the second position, the second portion makes contact with and presses against the first contact thereby preventing contact between the second contact and the second addressed device contact when the addressed device and addressing device are in an engaged position.

6. The addressing device of claim 5, wherein when the first switch is moved from the second position to the first position the first portion rotates out of contact with the first contact thereby causing the second contact to contact the second addressed device contact when the addressed device and addressing device are in an engaged position.
