Abstract: A system for cost-effective and accurate reading of RFID tags is provided. The system includes an RFID reader and one or more booster modules connected to the RFID reader. Each booster module has its own power supply, allowing for an amplification of a portion of the RFID signal that is output by the RFID reader. Thereby, the total power output of the system can be increased, and a read range and read accuracy can be improved due to additional antennas provided in the booster modules. In addition, it also becomes possible to reduce the power output by the RFID reader in order to increase the read accuracy of the same.

Abstract: A multi-function sensor system comprises a camera and a sonar device to enable various measurements to be achieved in a single unit, or as multiple co-located units, thus reducing the cost of having such multiple functions. 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 marine system, and corresponding method of transmitting an electronic signal in a marine environment, includes at least one pair of mutually coupled antennas disposed physically apart from each other, such that a separation gap exists therebetween. At least one of a first and second antenna of a given pair of the at least one pair of mutually coupled antennas may be communicatively coupled with at least one of the first and second antenna of any and all other pairs of mutually coupled antennas via a non-coaxial medium. The non-coaxial medium may be a cable with antennas of the at least one pair disposed at opposing terminals thereof, to support a contactless connection between at least a first and second transceiver module.

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. According to the invention, the actuator (5a, 5b) further comprises: at least two permanent magnets (23a, 23b) respectively generating first (B1) and second (B2) opposite magnetic fields; and an electric coil (25) provided between said magnets (23a, 23b) such that the winding of said coil (25) extends successively through said first (B1) and second (B2) opposite magnetic fields so that, when a current flows through said coil (25), the actuator (5a, 5b) is submitted to a resulting actuation force in a common driving direction for translating said mobile part (11) in said air gap (e).

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.
