A flow through photochemistry apparatus and methods of use are disclosed in the present application. One or more reactant materials are passed through a reaction chamber and are exposed to electromagnetic radiation. The reaction chamber has reflective walls arranged to reflect electromagnetic radiation across the volume of the chamber a plurality of times, thereby increasing the probability of the electromagnetic radiation interacting with the reactive materials. The reaction chamber may be used for sterilization and photochemistry applications.

Apparatus for reflecting an incident ray of electromagnetic radiation

A method is provided for positioning and orienting a platform such as a sample or workpiece relative to a frame of reference where the platform is a complex magnetic object that contains at least two magnetic domains with non-collinear magnetic moments and the method includes generating a spatially and temporally varying magnetic field so that each magnetic moment of the complex magnetic object interacts with the applied magnetic field. This can be used to performs an operation on a workpiece such as addition or removal of material. This can be used where the object includes a sample and, in each measurement configuration of the sample, radiation transmitted, reflected or scattered is measured from said sample material and analyzed to obtain information about the sample material.

Magnetic platform for sample orientation

A biological sample is analyzed for presence of a causing agent such as a virus, bacteria or cancer which generates a series of different states in the sample. The sample is separated into sub-samples where at least some of the sub-samples include portions of the sample at different states. Electromagnetic radiation interacts with the samples to obtain a spectrum of sub-sample properties which is compared with a plurality of reference spectra obtained from testing a plurality of sub-samples in respective ones of the different states to calculate a population distribution of the states of the sub-samples to obtain information about the causing agent. The population distribution can be analyzed at a single time or temporally over time to generate data relating to an effect of the causing agent. The population distribution is compared with a plurality of reference population distributions to generate data identifying the causing agent.

Spectral diagnostic system

A method for dynamically generating or interacting with an electromagnetic field includes providing a spatial array of conductive segments, a switching device operable on each of the conductive segments to either allow or block transmission of an electrical signal and a control device operable on the switching device. A sequence of the conductive segments are connected to form a conductive path where each segments intersects with at least two different ones of the conductive segments at a node. The switching device operates to connect a selected first one of the conductive segments with a selected second one of the conductive segments to form the sequence according to a logic signal from the control device. Power is supplied to the conductive path to produce an electromagnetic field which depends at least in part on the spatial arrangement of the connected sequence of the conductive segments.

Field programmable analog array

Particles are sorted into paths based on a measurable parameter by forming them into a stream in at least one duct carried on a body rotating around an axis where the duct is shaped so that the particles are accelerated to cause the particles separated into the duct to be aligned one after another in a row in the duct. The parameter of the particles are measured in the aligned stream one after the other and the particles are directed into one of a plurality of paths as determined by the measurement. In one arrangement the body comprises a disk member having a front face facing a supply conduit and the duct lies in a radial plane of the disk member. In one arrangement the measurement of the parameter is carried out by one or more measurement devices either carried on the disk or outside the edge of the disk.

Method and apparatus for singulating particles in a stream

A method to increase a probability of interaction of one molecule with a second molecule includes applying a sequence of temporally varying perturbations by acoustic forces and/or by electromagnetic fields or any combination thereof in at least two non-aligned directions to a volume containing the molecules. The sequence of temporally varying perturbations is chosen to produce a sequence of perturbed molecular configurations for the molecule in the volume and the sequence of perturbations is selected so as to cause the increase in probability. Initially data is obtained relating to orientations of the molecules and the sequence is selected based on the data. The data can be obtained by observation or by creating a known orientation using selected fields.

A method for growing plants includes both a seeder and a harvester both of which include arrangements for singulating the seeds and for measuring parameters of the seeds while singulated. This can be used for seeding selected seeds and for harvesting particular plants. The system operates by correlating information from the individual seeded seeds and from the harvested seeds in respect of a particular location on the growth medium and may include information relating the growth medium at the location. The location can be determined by seeding the plants in patterns which can be detected by a reader on the harvester. The system can be used to control selection of seeds to take into account soil conditions at the plant.

An optically thin sample of a sample material is analyzed by propagating probe electromagnetic radiation from a beam source along a plurality of different ray paths, directing each ray so that each ray path intersects upon the sample at a plurality of different locations where the rays interact with the sample material to cause a modification of the ray. The rays received at each of a plurality of detection spatial region are measured separately and the measurements analyzed to provide information about at least one property of the sample material at each interaction location. An analysis is carried out to trace the path of probe radiation from a location at the probe beam source to the detection spatial region on the detection surface so as to identify the interaction locations so as to provide information about the presence of target material at each interaction location.
