Abstract: An anti-skimming card reader device, and systems and methods for using the same, are provided. The card reading device can include a plate having a first surface and a second surface opposite the first surface. The device can also include a magnetic stripe reader disposed at the second surface. The magnetic stripe reader can include at least one sensor configured to acquire data from a magnetic stripe of a card disposed at the first surface and at least one proximity sensor configured to detect that the card is disposed at the first surface and to cause the at least one sensor to acquire the data from the magnetic stripe.

Abstract: Apparatus for controlling the output power of a laser diode the beam of which is directed in a selected direction toward a target so as to enable a missile or the like to be directed along the beam toward the target. The apparatus includes a circuit which supplies a variable amount of power to the diode, and a circuit which is responsive to the radiation emitted by the diode, and the latter circuit generates a signal which is proportional to the magnitude of the emitted radiation. A control circuit is provided which is initiated into operation at the time of firing of the missile and generates a signal which represents the desired increase in magnitude of the radiation emitted by the diode during the time of travel of the missile toward the target.
