Abstract: A self-mixing interferometer configured to monitor particulate material within a monitored region of space comprising a laser cavity assembly (1A) and an optical assembly (1B) configured to bathe the monitored region with laser light of the interferometer. A laser monitoring unit (1C) is configured to acquire an interferometric signal generated by the interferometer in response to light returned to the laser cavity assembly from said wavefronts by said particulate material. A processing module (1D) is configured to determine a property of the particulate material within the monitored region according to a wavelet transformation of the interferometric signal at least a part of which comprises a waveform of changing frequency.

Abstract: The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand May be configured for use as a training hand.

Abstract: A self-mixing interferometer configured to monitor particulate material within a monitored region of space comprising a laser cavity assembly (1A) and an optical assembly (1B) configured to bathe the monitored region with laser light of the interferometer possessing wavefronts having different directions at different respective locations within the monitored region. A laser monitoring unit (1C) is configured to acquire an interferometric signal generated by the interferometer in response to light returned to the laser cavity assembly from said wavefronts by said particulate material. A processing module (1D) is configured to determine a property of the particulate material within the monitored region according to changes in the frequency of a waveform within at least a part of the interferometric signal.

Abstract: Systems and methods are for performing operational assessment of a facility. An example method includes providing a facility information management server system, which includes a server system processor, a server system communication interface accessible by the server system processor, and a server system memory storing server system executable program instructions accessible by the server system processor. The example method further includes receiving a request from a client device, in which the received request indicates a facility operational assessment is to be conducted in relation to the facility. In response to the received request, the facility information management server system retrieves facility operational assessment data from a facility information repository database relating to the assessed facility. A facility operational assessment result can be determined based on the retrieved facility operational assessment data.

An example method may comprise: providing a facility information management server system comprising: a server system processor; a server system communication interface accessible by the server system processor; and a server system memory storing server system executable program instructions accessible by the server system processor; receiving a request from a client device, the received request indicating a facility operational assessment be conducted in relation to the facility; in response to the received request, the facility information management server system retrieving facility operational assessment data from a facility information repository database relating to the assessed facility; determining a facility operational assessment result based on the retrieved facility operational assessment data; and transmitting the determined facility operational assessment result to the client device.

Abstract: A facility information access system, comprising: a housing positioned in a location proximate to a facility, wherein the housing is accessible to pedestrians at ground level. The housing defines an internal cavity and comprises an access cover to block unauthorised physical access to the internal cavity. A facility information device housed inside the housing and comprises: a processor; a communication interface accessible by the processor and configured to allow exchange of information with devices external of the housing; and a memory storing executable program instructions accessible by the processor.
