    Abstract: Methods and systems for detecting an energy emission event are provided. In a method for detecting an energy emission event, a reference event signal is compared with a received event signal. In some embodiments, the reference event signal is associated with radiated energy having a predetermined temporal response. A detection signal is output when the received event signal corresponds to the reference event signal. In response to outputting the detection signal, imagery of a location in proximity to where the received event signal originated is captured or processed. Using the captured imagery and the detection signal, a determination of where the received event signal originated is made.

    Abstract: A position of a lens is detected by detecting, using a phototransistor, light that is emitted from a photodiode and that varies depending on lens position. A control unit divides a moving range of the lens into a plurality of areas, approximates a relationship between lens positions and current of the phototransistor for each of the areas, corrects a current of the phototransistor using the approximated relationship so as to obtain a corrected detection current having a linear relationship with respect to lens positions, and detects the position of the lens using the obtained corrected detection current.

    Abstract: A position detector includes a source of radiant energy, such as infrared light. A sensor is spaced from the source. The source and the sensor can be carried spaced apart from one another by a housing. Control circuits, carried by the housing, are coupled to the source and the sensor. Pulsed radiant energy, emitted by the source is incident on the sensor only when transmitted by a solid optical medium which has a predetermined orientation relative to the housing. When the medium has the predetermined orientation, the sensor receives transmitted radiant energy from the source. When the medium moves from the predetermined orientation, the sensor ceases to receive the transmitted radiant energy from the source, and the control circuits can generate an alarm indication.
