Abstract: Disclosed are electrolyte compositions for electrochemical devices, where the electrolyte compositions comprise a microemulsion and where the microemulsion comprises an aqueous phase and a water-immiscible phase. Also disclosed are microemulsion electrolyte compositions for electrically rechargeable electrochemical energy storage devices, including ion batteries (such as lithium ion, sodium ion, magnesium ion, calcium ion, and aluminium ion batteries), redox flow batteries and supercapacitors.

Abstract: A quiet headspace for the passenger in a vehicle (car/train/bus/aircraft etc.) which comprises a canopy to provide some passive attenuation of the noise coming from the surroundings and within the canopy a noise reduction system comprising, in combination one or more loudspeakers and one or more microphones located close to the passenger's head, and one or more microphones located around the periphery of the canopy.

Abstract: A media content aggregation system retrieves media content from a user's device or off-device media server and services accessible by the user and organizes the retrieved media content into a media content list. A user can filter and/or select various content items from the media content list and store the selected items in a media collection. The aggregation system is configured to parse and optimize the content items for completeness and optimal display on specified devices in addition to optimizing the media content list for display. The user can select the content items from this list with one click before assembling a collection. The media content aggregation system is configured to handle and store authentication information from the media server or services to obtain access to their media content and communicates a media content application that provides a user interface to a user on a client device.

Abstract: An analgesic composition is disclosed comprising a sub-analgesic dosage of a &mgr;-opioid agonist, optionally in the form of a pharmaceutically acceptable salt, and a sub-analgesic dosage of a &kgr;2-opioid agonist, optionally in the form of a pharmaceutically acceptable salt. There is also disclosed a method for producing analgesia in humans and lower animals which comprises administering concurrently to a human or lower animal in need of such treatment an analgesic composition of the invention.

Abstract: An active control system for attenuating tonal noise in a defined region is described. In its most basic form the system includes sensors for generating signals indicative of the residual noise in the region after attenuation and the uncontrolled sound affecting the region, signal processing circuit for processing the generated signals differently depending on the tonal content thereof, an adaptive filter supplied with at least one of the generated signals whose characteristic is controlled by the processing circuitry, a transducer for producing tonal-noise-attenuating disturbance in the region and delay means for delaying signals relating to the uncontrolled noise before or after or during the adaptive filtering. The system finds direct application in a personal headset or ear defender.
