Abstract

A connector system is provided for coupling an ionization emitter to an high voltage (HV) supply. The connector system includes one or more contacts for distributing voltage from the HV supply to the emitter. The connector system further includes a detection device that detects an element of an emitter that provides one or more properties of the emitter. The connector system further includes a detection logic device that sets one or more operating parameters of the HV supply according the one or more properties provided by the element of the emitter.

Claims

1. A connector system for coupling an ionization emitter to a high voltage (HV) supply, the connector system comprising:

(a) one or more contacts for distributing voltage from the HV supply to the emitter;

(b) a detection device that detects a pin of the emitter that provides one or more properties of the emitter, the pin being physically and electrically separate from the one or more contacts, the detection device including a ground contact and a plurality of sensing contacts configured for contact with the pin, each of the plurality of sensing contacts being held to a logical high level when not in contact with the pin, and each respective sensing contact being grounded when connected to the ground contact through the pin; and

(c) a detection logic device that sets one or more operating parameters of the HV supply according the one or more properties of the emitter.

2. The connector system of claim 1 wherein the detection device is a receptacle for receiving the pin.

3. The connector of claim 2 wherein the one or more properties of the emitter are defined by the length of the pin, and the detection device detects the length of the pin.

4. The connector system of claim 2, wherein the ground contact and the plurality of sensing contacts are disposed in the receptacle.

5. The connector of claim 1 wherein the emitter is an ionizing bar, and the detection device is a receptacle for receiving the pin.

6. The connector system of claim 1, wherein the HV is configured to shut down automatically when the pin is not detected by the detection device.

7. An ionizer device comprising:

(a) a high voltage (HV) supply;

(b) at least two ionization emitters connected in parallel to the HV supply, each connected to the HV supply by a connector system, each connector system including;

(i) one or more contacts for distributing voltage from the HV supply to the emitter, and

(ii) a detection device that detects an element of the emitter that provides one or more properties of the emitter, the element of the emitter being physically and electrically separate from the one or more contacts, and

(c) a detection logic device that sets one or more operating parameters of the HV supply according the one or more properties of the emitters, wherein one of the properties of each of the emitters is an operating voltage, and wherein the detection logic device is configured to supply the at least two ionization emitters with a lowest of the operating voltages of the respective emitters.

8. An ionization emitter comprising a pin that provides one or more properties of the emitter that are used to set one or more operating parameters of a high voltage supply that provides power to the emitter, the pin being physically and electrically separate from one or more contacts of the emitter that distribute voltage from the high voltage supply to the emitter, the pin being configured to connect a ground contact of a detection device with at least one of a plurality of sensing contacts of the detection device, each of the plurality of sensing contacts being held to a logical high level when not in contact with the pin.

9. The ionization emitter of claim 8 wherein the one or more properties of the emitter are defined by the length of the pin.

10. The ionization emitter of claim 8 wherein the emitter is an ionizing bar.
