Abstract: Various arrangements for establishing a link between two electronic devices are presented herein. A pairing mode may be activated to establish the link. A first electronic wireless device can determine that a distance to a second wireless electronic device meets a distance threshold criterion. In response to the pairing mode being activated and the distance to the second wireless electronic device meeting the distance threshold criterion, a graphic element, such as a glow effect, can be presented indicative of direction and distance to the second wireless electronic device.

Abstract: Systems and methods to distribute airflow in an internal space of a transport unit are described. The airflow distribution system may include an airflow distributor forming an airflow passage with a roof of the transport unit. The airflow distribution system may be also configured to allow airflow to discharge from a gap between the airflow distributor and the roof. The gap may be provided by at least one spacer between the airflow distributor and the roof. A back end of the airflow distribution system may be configured to provide a back pressure to the airflow passage while allowing the airflow to discharge. In operation, a front end of the airflow distribution system may be configured to receive airflow. The airflow can be distributed along the airflow passage and be discharged from the gap and the back end.

Abstract: Methods, associated products and apparatus are described for the production of biodegradable foam products using a controlled pressure increase due to compressed air and a controlled pressure decrease in pressure as key variables during a microwave heating cycle to produce a foamed product. The biodegradable product formed has improved characteristics including a density from 10 to 100 kg/m3; a soft and resilient structure; cushioning G-value characteristics to cushion an object with a fragility of 15 to 115; and a surface abrasion comparable to polystyrene.

Abstract: A method for the production of a biodegradable foamed product 7 from a base material and a blowing agent 1. The base materials are mixed with a blowing agent and any other required additives 1. The mixture 3, after extrusion 2, is placed in a microwave transparent mold 6 and processed in a microwave via distinct steps. The first step preheats the extrudate to a temperature just below the flash point 6. The second step 7 rapidly heats the extrudate beyond the flash point causing the extrudate to foam in the mold 7. By utilizing this method it is possible to produce shaped articles with uniform properties and with packaging properties such as compressibility, resilience and shock absorption.

Abstract: The method provided produces a bio-degradable foamed material with qualities of uniformity of mechanical and physical properties throughout the product including a foam thickness of up to one meter and a finished foam surface suitable for packaging applications. The parameters for producing such a product are selected from a range of variables which includes wall thickness, mold material, use of a susceptor and the type and composition of a susceptor, the number and arrangement of magnetrons and mold shape. Complex shapes produced by the process are also disclosed.

Abstract: A regulator system includes a power device and a sense device. During a normal operating mode, the power device is arranged to deliver current to a load, while the sense device is arranged to monitor the load current. An over-current mode is activated when the sensed load current exceeds a short-circuit current-limit. During the over-current mode, the power device is switched off such that the energy loss is minimized. Once the short-circuit condition is removed, the regulator system returns to the normal operating mode. The sense device is coupled to the load in such a way that the quiescent current of the regulator system does not rise with increasing load current. The regulator system is further arranged such that the short-circuit current-limit decreases automatically with increased operating temperature. The described regulator system has significantly reduced energy losses while also minimizing risks of thermal induced device failures during the short-circuit condition.

Abstract: A method for producing a material useful for forming a component for an electrochemical fuel cell is provided. More particularly, the component is formed of a sheet (10) of a compressed mass of expanded graphite particles. The component is treated with a water resistant additive sufficient to provide utility as a component in an electrochemical fuel cell. Preferably, the water resistant additive is a fluoropolymer material. More preferably, the water resistant additive is a polytetrafluoroethylene material. The treatment preferably occurs by coating and/or impregnating the water resistant material in the sheet of graphite particles.
