Abstract: A head-mounted display system includes a head-mounted display unit a display that, in use, is held in an operational position over a user's face. The head-mounted display system further comprises a flow generator configured to generate a flow of air, and an air guide arrangement coupled to the flow generator to enable the flow generator to direct air to, or draw air from, one or more selected areas in proximity of the head-mounted display system.

Abstract: A head-mounted display system includes a head-mounted display system, comprising a head-mounted display unit, comprising various pad options at various positions on the head including saddle shaped nose pads that deform under a reaction force applied to the apex of the nose to improve load distribution, forehead pads with an associated mounting structure and inserts that affect compliance and/or size, temporal pads configured to lie against the temporal bone which support some of the weight of the head mounted display system and, further stabilizing pads which are located on a rigid portion of the temporal arms and designed to extend along temporal regions of the users head.

Abstract: Tactile labels with raised touchable and readable projections extending away from a surface of a tangible good, container or package that allow people to quickly recognize and understand the content within the container, wherein the tactile labels may include data that can be extracted via image processing techniques.

Abstract: A distributed control system receives analysis data. The analysis data includes quality attributes of fluid samples and an indication of a plant location corresponding to the fluid samples. The system identifies one or more anomalies of fluid based upon the quality attributes of the plurality of fluid samples and attributes the one or more anomalies to one or more particular areas. The system triggers an alert, trigger control, or both, based at least in part upon the identified one or more anomalies and the attributed one or more particular areas.

Abstract: The invention provides a visibility aid for watercraft in the form a stream of water illuminated from within so that the stream of water is readily visible even in unfavorable conditions. A stream of water such as the telltale from the cooling system of an outboard motor is illuminated from within by light that exhibits total internal reflection. This makes the telltale easy to see, even at night, allowing a boat operator to know that the cooling system is functioning properly.
