  • Patent number: 9433886
    Abstract: A process for the separation of carbon dioxide from gas mixtures is disclosed in which a metal oxide sorbent, which is used to capture and release carbon dioxide, is recycled. The process incorporates the regeneration of the carbon dioxide capture capacity of the metal oxide to maintain a high capture capacity over many cycles. The regeneration involves hydrating the metal oxide and then heating the resulting metal hydroxide under a gas atmosphere that is effective to suppress the dehydration of the hydroxide so that dehydration occurs at an elevated temperature. The regeneration may also be used independently from the carbon dioxide separation process to produce, from a metal hydroxide, a metal oxide having an enhanced resistance to attrition and fragmentation.

  • Patent number: 9319794
    Abstract: A surround sound system for reproducing a spatial sound field in a sound control region within a room having at least one sound reflective surface. The system uses multiple steerable loudspeakers located about the sound control region, each loudspeaker having a plurality of different individual directional response channels being controlled by respective speaker input signals to generate sound waves emanating from the loudspeaker with a desired overall directional response. A control unit connected drives each of the loudspeakers and has pre-configured filters based on measured acoustic transfer functions for the room for filtering the input spatial audio signals to generate the speaker input signals for all the loudspeakers to generate sound waves with coordinated overall directional responses that combine together at the sound control region in the form of either direct sound or reflected sound from the reflective surface(s) of the room to reproduce the spatial sound field.

  • Publication number: 20130059696
    Abstract: The invention relates to an exercise system/device for exercising a user's upper limb. The exercise system/device is intended for use in rehabilitating patients suffering hemiparesis that causes one upper limb to be at least partially paralysed. For example, the exercise system/device can be used for neuroplastic retraining rehabilitation techniques for enabling patients to regain control of their paralysed upper extremities, including shoulders, elbows, wrists and fingers, but primarily their shoulders and elbows via larger arm movements. This is achieved through the use of an elongate handle and a motion sensing device associated with the handle for communicating the user's movements of the A handle to a gaming system. Although the exercise system/device is primarily for rehabilitation of patients suffering hemiparesis, it will be appreciated that it may also be used by any person for bilateral training and exercising upper limbs.
