Abstract: A filter system having a filter media retainer seal includes: at least one underdrain block having a top wall, a bottom wall, and a pair of side walls extending between the top wall and the bottom wall; a filter media retainer mounted onto the top wall of the at least one underdrain block; and at least one rib positioned between the underdrain block and the filter media retainer. The at least one rib forms a seal between the underdrain block and the filter media retainer, and prevents filter media from entering the underdrain block. The at least one rib can be monolithically formed to the at least one underdrain block. Alternatively, the at least one rib is monolithically formed to the filter media retainer. The rib is crushable and/or it bites into a surface on the adjoining part to reduce or eliminate the need for a separate sealant.

Abstract: A filter system for filtering particles from a liquid includes an underdrain assembly having an underdrain defining at least one underdrain chamber and a media retainer assembly. The media retainer assembly includes an upper filter media retainer plate defining a plurality of hopper-shaped cavities and a lower filter media retainer plate defining a plurality of hopper-shaped cavities corresponding to the plurality of hopper-shaped cavities on the upper plate. The plates are in a nested arrangement such that the hopper-shaped cavities on the upper plate are in alignment with the corresponding plurality of hopper-shaped cavities on the lower plate to define a plurality of passages therebetween and allow for the passage of the liquid while preventing the passage of a filter media. During a backwash operation, the upper and lower plates are relatively moveable such that the backwash fluid releases any particles lodged in the passages between the plates.

Abstract: Methods of detecting and predicting ovulation and a period of fertility include determining a series of measures indicative of the basal body temperature of a female human user to identify a temperature change event. The method includes obtaining, within a first 24 hour period, a plurality of first readings of the temperature of the female human user at intervals over a first extended period of at least an hour. The plurality of first readings are then processed to determine at least one first representative temperature reading representative of the basal body temperature of the user for the first extended period and the at least one first representative temperature reading is stored. The method is repeated for at least second and third 24 hour periods and the representative temperature readings are provided for analysis to identify a temperature change event for the female human user.

Abstract: A method of providing information relating to the fertility of a female mammal comprising the steps of: (i) taking multiple temperature readings from the female mammal during an extended period; (ii) identifying and disregarding temperature readings having one or more characteristics of irrelevant or faulty data; (iii) obtaining one or several representative temperature values for the extended period; (iv) repeating steps (i) to (iii) over multiple extended periods; (v) analyzing the representative temperature values obtained over multiple extended periods for one or more patterns in the representative temperature values indicative or predictive of ovulation in order to provide information relating to the fertility of the female mammal to a user, wherein the representative temperature values are not the maximum or minimum temperature readings obtained for the extended period; and related uses and apparatus.

Abstract: Apparatus and methods for training a person in route management are based on a personal computer. The apparatus may be used for example to train a bus driver to follow a new or changed route. A data store stores data streams corresponding to different kinds of information of the route, including video of the route, audio data, sound data, GPS and time data, and vehicle engine management data. A VDU and loudspeaker are used as output devices to present the plurality of data streams to a user such that they are co-related to the route to be followed. Data streams corresponding to different route information are not combined in the data store, but comprise cross-referable data. The computer is programmed to present the first data stream and the further data stream in a co-related manner via the output devices and in dependence upon the cross-referable data.
