Abstract: A nozzle for a fan assembly is described. The nozzle includes a first duct through which a first airflow moves, the first duct having a first outlet for emitting the first airflow. The nozzle further includes a second duct through which a second airflow moves, the second duct having a second outlet for emitting the second airflow. The first and second outlets are arranged such that the first and second airflows collide to generate a combined airflow having a direction defined by the relative flow rates of the first and second airflows. The first duct then includes a portion moveable to vary the flow rate of the first airflow.

Abstract: A fan assembly, including a fan body including first and second retention assemblies and an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly attached to the fan body includes one or more flexible filter media, a first engagement element positioned at first edge of the filter media, and a second engagement element positioned at a second, opposite edge of the filter media. The filter assembly is furlable, and the first and second engagement elements releasably engage with the respective first and second retention assemblies of the fan body to retain the filter assembly tautly over the inlet surface in an at least partially unfurled state, such that, in use, airflow drawn through the air inlet by the motor-driven impeller is drawn through the filter media. The fan body is cylindrical in shape and the filter assembly wraps around substantially all the fan body.

Abstract: There is provided a container maneuvering apparatus arranged to provide an interface between a container-conveying system and a container-storage system. More specifically, there is disclosed a container maneuvering apparatus arranged to load/unload a container into/from a carriage. Optionally, the carriage is a Magway carriage. The carriage can be made stationary before loading/unloading the container by the container-conveying system. The carriage and container can match velocities so that both are moving, but at the same velocity, whilst loading/unloading operations are performed by the container maneuvering apparatus.

Abstract: There is provided an air-treatment device including an airflow generator for generating an airflow, an adsorbent material for adsorbing one or more airborne contaminants, the adsorbent material being arranged such that at least a portion of the airflow passes through the adsorbent material, a heater arranged to heat a portion of the adsorbent material to desorb adsorbed contaminants, and a photocatalytic reactor arranged to receive air containing the contaminants desorbed from the heated portion of adsorbent material. The photocatalytic reactor includes a photo-catalyst for photocatalytic degradation of one or more of the contaminants, and one or more light sources for illuminating the photo-catalyst to facilitate photocatalytic degradation. The air-treatment device is arranged such that at least a portion of the airflow that has not passed through the heated portion of the adsorbent material contacts the one or more light sources.

Abstract: There is provided a photocatalytic reactor arranged to receive one or more airborne contaminants. The photocatalytic reactor includes a photo-catalyst for photocatalytic degradation of one or more of the contaminants disposed on a substrate, and a light-emitting diode circuit board comprising a circuit board with one or more first light-emitting diodes mounted to a first side of the circuit board and one or more second light-emitting diodes mounted to a second side of the circuit board. The substrate is arranged to be illuminated by both the one or more first light-emitting diodes and the one or more second light-emitting diodes in order to facilitate photocatalytic degradation.

Abstract: In one embodiment, a mobile data analysis system generates mobile reports. In this context, a mobile report represents information collected by a mobile device user and provided as input to a report form displayed by an associated mobile device. The collected information may, for example, include information relating to an activity or event, information relating to a particular person, entity, or location, or any combination thereof. A mobile report may be based on a report template. A report template defines one or more data fields and other property information to be included in a mobile report. A mobile report may be sent to a server to generate one or more data objects, and one or more data object links between the data objects from a first mobile report, the data objects from a second mobile report, and exiting data objects that are maintained at the server.

Abstract: A storage system as disclosed can maximize storage capacity whilst remaining scalable. A transporting device is arranged to form a cluster with a reconfigurable physical topology. A transporting device can cooperate with a portion of a surface, and with at least one other transporting device in a cluster with a reconfigurable physical topology. An item receiving space and a relocating unit permit relocation of the transporting device within the cluster by way of interaction with the portion of the surface.

Abstract: Aspects of the present disclosure address systems and methods for clock tree synthesis (CTS). A first iteration of CTS is performed to generate an intermediate clock tree for an integrated circuit (IC) design that includes one or more macros. Target pin insertion delays (PIDs) for the one or more macros are computed based on the intermediate clock tree using a linear program. A second iteration of CTS is performed using the target PIDs for the one or more macros to generate an optimized clock tree for the IC design.
