Abstract: Echo detection and monitoring systems and methods are provided. According to the invention, the outgoing and incoming voice bearer channels of a voice communication are monitored. The outgoing and incoming signals are time aligned, and measures are then taken to determine whether echo is present in the signal. In accordance with an embodiment of the present invention, the outgoing signal is fed through an adaptive filter.

Abstract: An airship deployment system comprises an airship of unique shape having laminar flow over this shape to enable low power propulsion, capable remote control, comprising an inflatable body; a propeller assembly for station keeping and repositioning said airship and capable of being folded into a compacted position and unfolded into an operational position; and a payload, comprising gas for inflating said inflatable body; and means for transferring data between said airship and a remote location; and a missile for carrying said airship in a compacted state to a predetermined location and altitude, and releasing said airship at said predetermined location and altitude. When said airship is released from said missile said inflatable body is inflated and said propeller assembly is unfolded into said operational position.

Abstract: An apparatus for applying laser light to the retina of the eye comprises a retina image obtaining means for obtaining the image of a retina. A retina image display displays the required retina image, and reference data receiving means receives, from an operator, data relating to a treatment to be performed. Template generating means generates a reference template on the retina image, and target position receiving means receives data related to at least one target point to which light is to be applied based upon the received reference data. Current retina position detecting means acquires a current retina image, and laser light application means directs and applies laser light to a retina.

Abstract: A wearable hypermedium information retrieval system for displaying predetermined digitized data, having a computer having an I/O port; a large capacity information storage and retrieval device interfaced with the I/O port adapted to receive a memory medium containing the predetermined digitized data, the storage and retrieval device being adapted to access the data on the memory medium and to provide the data to the I/O port means, the predetermined digitized data being further organized in a hypermedium format for hypermedium access and retrieval; a virtually hands-free command control device presenting no interference to ordinary use of the hands of the user to provide input commands from the user to the computer via the I/O port means; and a headset adapted to be worn by the user and a head mounted image display supported by the headset having a virtual image display having an eye-piece adapted to be positioned in front of one eve of the user and to display video display information from the computer.

Abstract: A microbiocidal composition including a first component comprises a guanidine compound, a second component which comprises either prochloraz, propiconazole or iodocarb, wherein the weight ratio of first component to second component is in the range of from about 32:1 to about 1:16. The microbiocidal composition provides effective and broader control of micro-organisms in various industrial systems and for household products, agricultural products and biomedical products.
