    Abstract: A sensor package includes a packaging formed by a package bottom, first and second sidewalls extending upwardly from first and second opposite sides of the package bottom, and third and fourth sidewalls extending upwardly from third and fourth opposite sides of the package bottom, the sidewalls and package bottom defining a cavity. An integrated circuit is attached to the package bottom. A plate extends between two of the sidewalls within the cavity and is spaced apart from the package bottom. Sensors are attached to a top surface of the plate on opposite sides of an opening. Wire bondings electrically connect pads on a top face of the sensor to corresponding pads on a top face of the integrated circuit, for example by passing through the opening in the plate or passing past a side end of the plate. A lid extends across and between the sidewalls to close the cavity.

    Abstract: A method is for detecting one or more objects in a detection zone using a time-of-flight sensor. The method includes emitting optical radiation via the emission circuitry of the sensor and subsequently capturing the reflected optical radiation using the reception circuitry. This captured radiation is quantified in terms of photons, and measurement circuitry determines both the amount of these photons and the distance from the sensor to the object(s). An analysis of the photon count, combined with the calculated distance, is used to determine the presence or absence of objects within the detection zone.
