Abstract: Embodiments provide a skimming detection device including a one or more sensors configured to detect characteristics that may be used to detect the presence of a skimming device. Sensor data generated by the sensor(s) may be compared to reference sensor data to detect the presence of a skimming device. An output that indicates whether a skimming device is not present, likely present (e.g., the consumer or user should assume the scanned device contains a skimmer or has otherwise been compromised), or confirmed to be present may be generated and presented to a user. Such capabilities may enable user to quickly scan a device (e.g., an ATM, a fuel pump, etc.) to determine whether a skimming device is present and take action to mitigate the use of any detected skimming devices.

Abstract: Sound suppression devices may include a baffle system or stack having a plurality of baffle disks where at least a first portion of the disks include a first set of gas ports and at least a second portion of the disks include a second set of gas ports. The baffle system may be configured to act as a compressing piston. When a bullet leaves a muzzle of a firearm and enters a suppression device, the baffle system acts as a compressing piston and moves forward with the gas pressure caused by the firing of the bullet. As the bullet begins to enter each baffle disk, the pressure starts to subside until there is a point where there is equalization between gas pressure and, for example, tension on a piston spring within the baffle system. After this point, the piston is driven back into place by the releasing of the spring tension.

Abstract: The present application relates to systems, methods, and computer-readable media for deterring video piracy. In aspects, a light source generates an infrared (IR) light spectrum that is projected onto a surface, such as a movie theatre screen. The IR light spectrum may form an watermark that is invisible to members of the audience that are viewing video content projected onto the surface, but that obfuscates at least a portion of video content captured by video recording device that is being used to capture a recording of the video content projected onto the surface. In aspects, a frequency of the IR light spectrum emitted by the light source may be periodically modified to make it more difficult to filter out the watermark.
