Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Abstract: Aspects of this disclosure relate to one or more particles that move within a container in response to a magnetic field. A measurement circuit is configured to output an indication of the magnetic field based on position of the one or more particles.

Abstract: Aspects of this disclosure relate to particles that can move in response to a magnetic field. A system can include a container, particles within the container, and a magnetic structure integrated with the container. The magnetic structure can magnetically interact with both an external magnetic field and the particles. Related methods are disclosed including magnetic field detection methods based on detection of particles within a container.

Abstract: A method includes identifying a plurality of content types in a database of a social network, wherein members produce and request content of different content types from the database. Job types to be performed on each content type are identified, when requests for content are received from members of the social network. A sharding process for each content type is selected based on the job types to be performed on the content types. The database is sharded into first group of shards for content types having job types that are parallel processing efficient and into second group of shards for content types having job types that are linear processing efficient. The first and second group of shards define a multi-shard database. Requests for contents are serviced from the first group or the second group of shards from the multi-shard database depending on the job types associated with the requests.

Abstract: A system and method for scheduling tasks in a calendar of a user. Multiple task entries are received from the user, and the task entries are ranked based on a deadline of each of the task entries. A length of time required to complete each task entry is determined, and a time-consuming calendar entry for each task entry is created in the calendar of the user based on the ranking of each task entry, the determined length of time required to complete each task entry, and existing calendar entries in the calendar of the user. The created time-consuming calendar entries are provided to the user. Machine-readable media are also provided.

Abstract: Filtration apparatus (102) is provided for the treatment of waste water, sewage and/or effluent. The apparatus includes a housing (4) having at least a first filter layer (16) provided therein. The first filter layer (16) includes biological filtration-means including one or more organisms and a substrate material to filter waste water, sewage and/or effluent located thereon, passing thereover or therethrough in use. The apparatus includes at least a second filter layer (20) for filtering fluid that has passed through the at least first filter layer. The second filter layer (20) includes an absorbent material that is different to the substrate material of the at least first filter layer (16).

Abstract: The invention comprises a vehicle and seating arrangement having a central hub with four sides surrounded by four seats. The seats are arranged adjacent a respective side of the hub and facing substantially parallel to the side of the hub. In at least one embodiment, the arrangement provides access for each passenger to the aisle.

Abstract: This invention relates to a process for preparing zirconium oxide, in its various forms, including zirconium-based mixed oxides. There is described a process for preparing a zirconium oxide in the absence of a cerium salt which comprises precipitating a zirconium hydroxide from an aqueous solution of a zirconium salt by reaction with an alkali in the presence of a controlled amount of sulphate anions at a temperature not greater than 50° C. and then calcining the hydroxide to form an oxide, wherein the oxide thus formed is essentially sulphate free. Catalysts and ceramics can be produced from the product oxides having improved thermal stability and improved sinterability, respectively. A particular use of the product oxide is as a promoter or catalyst support in automobile exhaust systems.

Abstract: A process for preparing zirconium-cerium-based mixed oxides which comprises reacting an alkali with an aqueous solution of a zirconium salt containing 0.42-0.7 mole of sulphate anion (SO42?) per mole of zirconium cation at a temperature of not greater than 50° C., in the presence of a cerium salt to form a cerium-zirconium mixed hydroxide, and then calcining the cerium—zirconium mixed hydroxide to form a mixed oxide. The mixed oxides possess good thermal stability and are essentially single phase and are suitable as promoters and catalyst supports in, particularly, automobile exhaust systems.
