The camera and sonar device may be calibrated individually and as a system to provide an accurate and correlated set of optical and acoustic data.

Abstract: A system and corresponding method perform underwater distance determination. The system comprises a hydrophone unit (HU) located at a reference point, a first sensor module (SM), and a second SM, each located underwater. The first SM sends a first sensor-to-hydrophone data signal and a first sensor-to-hydrophone synchronization signal to the HU and sends a first inter-sensor synchronization signal to the second SM. The second SM sends, responsive to receipt of the first inter-sensor synchronization signal from the first SM, a second inter-sensor synchronization signal to the first SM. The second SM sends a second sensor-to-hydrophone data signal to the HU. The first SM measures a time value representing a total travel time of the first inter-sensor synchronization signal from the first SM and second inter-sensor synchronization signal from the second SM and calculates a distance between the first SM and second SM based on the time value measured.

Abstract: A propulsion system includes a drive shaft movable in rotation about an axis of rotation, a low-pressure compressor driven in rotation by the drive shaft, the low-pressure compressor having a mean radius, a fan shaft, a fan driven in rotation by the fan shaft, a reduction mechanism coupling the drive shaft and the fan shaft, having a reduction ratio, and an inlet channel which extends between the fan and the low-pressure compressor, the inlet channel having an inlet adjacent to the fan and an outlet opposite the inlet and adjacent to the low-pressure compressor, the inlet having a mean radius. A first ratio between a ratio of a mean radius of the inlet channel and the mean radius of the low-pressure compressor, and the reduction ratio of the reduction mechanism, is strictly less than 0.35.

Abstract: The present invention describes a system and method for controlling interactive video, including a remote control device allowing the user to interact with the video. The method allows bringing the “lean-forward” hypervideo experience to a “lay-back” environment such as the TV screen. The method also allows for the creation of a single system that combines both the social aspects of the “lay-back” and the “lean-forward experience” into a new type of rich media viewing experience.

Abstract: The invention relates to an electromagnetic actuator to be mounted in a haptic-feedback control device (1) for transmitting a haptic feedback to a user, wherein said actuator (5a, 5b) comprises a fixed portion (9) and a mobile portion (11), said fixed (9) and mobile (11) portions forming a magnetic circuit defining at least one air gap (e) between said fixed (9) and mobile (11) portions.

Abstract: A viewer interaction system and method receives video data from a video source and identifies object content in the received video data. A video signal is generated that represents the video data. That video signal is communicated to a display device which displays a video image representative of the video signal. The system and method monitor user interaction with the displayed video image and selects an interactive activity based on the user's interaction with the displayed video image and the identified object content in the received video data.

Abstract: More and more personal or confidential information is stored in storage devices such as but not limited to, laptops, cell phones or USB keys, which are mobile per essence. Due to their mobility, such devices tend to be left unattended or even be lost, compromising the security of the data. This invention is a method to prevent access to the data on a mobile storage device when the intended recipient or user is not in closed range. The invention relies on the use of wireless communication protocol such as but not limited to RF, Bluetooth or Wi-fi to pair a security device with the storage device to enable its functionality. When the security device is not in communication range of the storage device, the data is made inaccessible. A data storage device may include a wireless communication interface used to secure the data, wherein the data storage is partitioned, with each partition having a different security profile.
