Abstract
A security device is provided including a product presence sensor configured to sense a change in product presence relative to the product presence sensor and a directional element configured to direct the product presence sensor in a sensing direction.
Claims19
A security device comprising:
- an attachment coupling configured to attach the security device to product packaging, the product packaging having a product disposed therein;
- a product presence sensor configured to sense a change in product presence within the product packaging, the change in product presence being relative to the product presence sensor and indicative of an occurrence of a product being removed from the product packaging, the product presence sensor comprising:
- a capacitance sensor, and
- a driven shield;
- and
- a directional element configured to direct the product presence sensor in a sensing direction;
- wherein a first portion of the driven shield is disposed on a common plane with the capacitance sensor and a second portion, that is electrically connected to the first portion, of the driven shield is disposed in a plane between the capacitance sensor and the directional element and parallel to the common plane.
