Abstract: The technology relates to a medical system that includes a video laryngoscope, an endoscope connector removably attached to a housing of the laryngoscope, and a steerable endoscope having an electrical interface at the proximal end for receiving steering commands from the laryngoscope. The endoscope connector is attached to the video laryngoscope using one or more magnets and includes several additional mechanical features configured to inhibit lateral and vertical movement of the connector relative to the laryngoscope. The connector includes a port into which the proximal end of the endoscope is inserted. The connector includes an electrical interface that, when the connector is attached to the laryngoscope and the endoscope is inserted into the port of the connector, is in contact with both an electrical interface of the laryngoscope and an electrical interface of the endoscope, thereby providing an electrical connection between the laryngoscope and the endoscope.

Abstract: A large scale LED display system (12) is provided on a building structure (100). The system has a screen (12) formed of a number of side by side display panels (14) which may be foldable or rollable. Each panel has a number of equally spaced transparent polycarbonate tubes (80) which house pixel units (50) of LEDs (51) connected to printed circuit board (120) and a row controller (121) for controlling luminance of the LEDs. A bus member (54) convey power and video control signals from a panel controller (77) to each row controller. The panel controller has an initialising process adapted to allocate temporary addresses for the tubes and determine screen size accordingly. Video segments are extracted by the row controllers based on the addresses associated with the video control signals from the panel controller.

Abstract: A life raft or ocean survival unit (1) is capable of self-righting upon capsize, even when occupied by one or more survivors. The life raft (1) comprises a hull-shaped ballast chamber (5) which fills with water upon inflation of the life raft and provides added stability to the vessel and in part see self-righting capabilities to the life raft. Water is sucked in through membrane valves located at the rear of the ballast chamber. The life raft also comprises a canopy (4) and inflatable base section (3), wherein the inflatable base section may be compartmentalised to prevent sinking of the unit in the event of a puncture deflation.
