Abstract: Certain aspects of the present disclosure provide measures, including apparatus, methods, circuitry, and computer program products for use in impact detection. Example apparatus comprises a plurality of sensors. The apparatus is configured to determine whether a user is wearing an item in which the apparatus is comprised, and in response to a positive determination, operate the apparatus in an active operating mode. The active operating mode comprises operating one or more sensors in the plurality to generate data associated with motion of the user at a first sampling rate.

Abstract: A flexible energy absorbing system comprising a material coated, impregnated and/or combined with a strain rate sensitive substance is disclosed. It is formed so as to define repeating adjacent cells, each cell having a re-entrant geometry such that, upon impact, the material locally densifies at the impact site.

Abstract: A component 2 for a bearing, the component 2 comprising a bearing surface 4, wherein the bearing surface 4 is formed so as to be tapered at rest, thereby offsetting deformation of the bearing during an operational condition which generates an induced angle in the bearing surface 4 or an opposing surface of the bearing. A method of manufacturing a bearing is also provided. The method comprises: determining an induced angle of a component 2 of the bearing caused by deformation of the bearing during an operational condition: and providing a surface 4 of the component 2 or an opposing component with a taper at rest so as to offset the induced angle generated during the operational condition.

Abstract: Disclosed herein are flexible energy absorbing systems and methods of manufacturing flexible energy absorbing systems. The systems include one or more cells of a strain rate sensitive material and having a re-entrant geometry. Some of the systems have an anisotropic geometry to provide a different response to impacts from different directions.

Abstract: The disclosure extends to systems and methods of labeling compounds of essential oils with a marker. In an implementation, the labeling of the compounds of essential oils may comprise using a fluorescent dye that covalently links the hydroxyl group to the fluorescent dye, such that the compound may be detected using a fluorescence microscope.

Abstract: Herbal compositions and techniques for suppressing appetite and managing weight are described. These compositions and techniques are based at least in part on beneficial results showing that benzylamine can suppress appetite. In at least one embodiment, a composition that includes an effective amount of benzylamine and an effective amount of at least one benzylamine enhancer may be utilized for appetite suppression.

Abstract: A tandem beam splitter for real-time polarization difference sensing, with at least one body having two faces that isolate two orthogonal planes of information from a common stimulus input in series, with a first of the two faces isolating a first plane of information and a second of the two faces isolating a second plane of information which is orthogonal to the first plane.

Abstract: A polarization filter utilizing Brewster's angle. The polarization filter includes a stimulus receiving body having more than one facet. At least two of the more than one facet being arranged at Brewster's angle (relative to the plane of polarization of the incident stimulus) and positioned in different radial orientations (relative to the incident stimulus) which are adapted to provide differential transmission or reflection of polarized electro-magnetic radiation coming from a common source.

Abstract: A method for polarmetric analysis of scattering media. A first step involves directing stimulus from a linearly polarized stimulus source at a sample. A second step involves directing the stimulus coming from the sample through a collimating system into a polarization segregation unit which causes the stimulus to be segregated into a linearly polarized unscattered component and a depolarized scattered component. A third step involves quantification of scattering processes through computationally comparing the unscattered component and the scattered component.

Abstract: A flexible energy absorbing material in which a dilatant material (6) is impregnated into or supported by a resilient carrier (1). The dilatant material remains soft until it is subjected to an impact when its characteristics change rendering it temporarily rigid, the material returning to its normal flexible state after the impact. The carrier can be a spacer fabric, a foam layer or modules or threads of dilatant material contained between a pair of spaced layers. Methods of manufacturing the energy absorbing sheet are also disclosed.
