Abstract: An elevator drive cassette configured for use in driving the movement of an elevator car along a rail or rack, the elevator drive cassette including: a driven pinion and drive shaft configured to be driven by a drive motor associated with the elevator car; a mechanical coupling; at least one further pinion configured to be driven by the driven pinion or drive shaft via the mechanical coupling, wherein both the driven pinion and at least one further pinion are configured to engage the same rail or rack.

Abstract: Embodiments involve harmonising one or more geographically or temporally distributed renditions with at least one backing clip, comprising a calibration module for selecting a parameter of one or more aural or visual characteristics of the first rendition, a backing clip selector in communication with a backing clip database, a reference selector for selecting reference clip for modification of the first rendition, a modification module for applying a computational process to the first rendition or the backing clip to modify an aural characteristic of the first rendition or the backing clip to reduce the difference between the first rendition or the backing clip and the reference clip in the aural characteristic, and a mixing module to combine one or multiple renditions with the backing clip after modification.

Abstract: An apparatus for generating electrical power downhole comprises a housing located in a drillstring. A primary flow channel is formed through the housing. At least two secondary flow channels are located in the housing and arc laterally displaced from the primary flow channel, A fluid driven electrical generator is positioned in each of the at least two secondary flow channels. A controllable flow diverter is associated with each of the secondary flow channels to controllably divert at least a portion of a fluid flow m the primary flow channel to at least one of the at least two secondary flow channels to drive the generator therein.

Abstract: A method of monitoring the operation of a networked computing system as described, including the steps of obtaining configuration information that identifies at least one software module in the networked computing system and also identifies an instruction used to invoke that module monitoring network traffic at at least one point in the network to detect requests that include the instruction to invoke the module calculating operational information of the software module based on the detected requests.
