Abstract: A method and apparatus for integrated ATM surveillance of an area of interest, such as an automated teller machine (ATM), is presented. An embodiment includes a surveillance system for an ATM utilizing multiple cameras aimed at the user, the card slot, the cash dispenser, the surrounding areas and internally in the card reader (to link the card used to the ATM user). The cameras are constantly powered and begin to record images after a sensor is activated. A buffer of recorded imagery is maintained such that when the sensors are activated, the video processing equipment can store a pre-defined amount of time before the sensor is activated. The buffer allows for the video capture of events just prior to the activation of the sensor. A time stamp and any other relevant data from the cameras may also be included with the stored recorded video.

Abstract: An apparatus and method is provided for measuring magnetic force response time due to the magnetic viscosity of materials and for measuring total energy exchanged due to relative motion of magnetic materials. Voltage and current versus time through an electromagnet is measured and recorded. Corresponding force versus time is measured for magnetic forces applied to a material under test in response to energizing the electromagnet to determine effects of magnetic viscosity of the material under test. A test system is also provided for measuring energy exchanged due to the relative motion of magnetic materials. Absolute values of transferred mechanical energy and electrical energy are combined to determine the total energy exchanged by interaction of a permanent magnet and an electromagnet.
