Abstract: A device for interfacing an input device and a computer includes a microprocessor in communication with a memory, the memory storing download instructions and having a re-writable memory area for storing input device driver data downloadable by the microprocessor using the download instructions. The microprocessor is programmed to use the input device driver data to enable data transmission between the computer and the input device. In an alternative device, the microprocessor is programmed to extract input device driver data from data transmitted to the device in a standard input device protocol and to save the input device driver data in the memory. An upgradeable KVMA and KVM switch and extender including such devices are described.

Abstract: Devices for reducing and determining the skew between colour video signals transmitted over at least two different video cables are described. A KVM extender including such devices is also described. The skew reduction device includes a plurality of video signal transmission tracks selectably connectable to each of the video cables to increase the video signal transmission path length so as to more closely matching the total video signal path length for each of the colour video signals. The skew determination device comprises a processing device, a signal generator for applying measuring signals to each of the video signal cables and signal detection circuitry to receive measuring signals transmitted over the video signal cables. Detection signals are output to the processing device which is programmed to determine an indication of the transmission path length difference between the video signal cables.

Abstract: A system converting seats into couches, characterized in that it comprises—with at least one set of seats (1, 2) comprising at least one base (d) and one backrest (f) connected by a linkage (e) allowing to move said seat into the seating mode, the base and the backrest assuming a first relative angular position or into the couch mode, the base and the backrest then assuming a second relative angular position—a support (3) for said seats, a conversion mechanism driving each linkage of each seat to convert each seat (1, 2) into a couch in such manner that at least two consecutive seats within a column of the set of seats shall be moved from the seating mode one behind the other into the couch mode one above the other.

Abstract: A system for transmitting electrical signals between a computer and peripherals along a twisted pair cable. The system includes a computer interface, a peripheral interface and a twisted pair cable in communication between the computer interface and the peripheral interface. Video and audio signals from the computer are transmitted via the twisted pair cable to the peripherals. Peripheral signals can also be communicated between the computer and peripherals via the twisted pair cable.

Abstract: A serial data routing device for use in routing serial data between a computer and a peripheral device. The data routing device includes a computer data converter which communicates data under the USB protocol with a computer and which converts data received from the computer into converted computer data. A peripheral data converter is also included which communicates data under the USB protocol with the peripheral device and which converts data received from the peripheral device into converted peripheral data. A data router is provided in communication with the computer data converter and the peripheral data converter and transfers converted computer data and converted peripheral data between them. It includes a data routing controller which controls the routing of the converted computer data and the converted peripheral data between the computer data converter and the peripheral data converter such that the computer and peripheral device operate as though directly connected by a USB bus.

Abstract: The movable class-partitioning divider for an illustrative airliner passenger cabin comprises in particular: a device to lock said divider into a mooring adapter selected during the translation of the divider along a guide rail configured longitudinally in said cabin and unlocking it before such translation takes place; a device connecting at least one first connector, which is firmly affixed to a movable support mounted on a longitudinal rail solidly joined to the cabin, to a second connector solidly which is firmly affixed to said mooring adapter; a device operating said locking and connecting devices during translational operation; a device to preclude actuating said operating devices as long as at least the first connector is outside a given connection zone to said second connector firmly affixed to said mooring adapter. Application: passenger transportation.

Abstract: There is provided video switching circuitry for use in a KVM switch and similar devices. Video signal switching circuitry can supply video signals from a one of a plurality of video sources connected to the circuit to a display device connected to the circuit. The high data signalling rate signals are converted into a greater number of lower data signalling rate signals for switching by a bus architecture. Also provided are video display systems in which analogue and digital video signals are switched synchronously to allow them to be displayed on common or separate display devices. Also described is a high-resolution monitor digital video data switching device.

Abstract: An air injection device for attachment to the exhaust manifold of an internal combustion engine is described. A one-way or check valve permits air to be drawn into the air injector to the exhaust manifold when the pressure inside is less than atmospheric to allow more complete burn of unconsumed fuel. On the pressure stroke, the valve closes and prevents untreated exhaust gases from exiting the injector. The valve is designed with mechanisms, such as small protrusions, on the valve and/or on the seat or circumferences that the valve contacts to reduce or prevent sticking of the valve. In one embodiment, the valve may be spherical, and in another embodiment, the air injector may be provided with a mechanism to manually adjust the air flow through the injector.
