Abstract: A pump and mixing device for pumping a liquid from a container and mixing with a diluent. The pump and mixing device comprises a body member having an input body portion and an output body portion with a flexible wall defining a pumping chamber between the input body portion and the output body portion. The input body portion has an input aperture for enabling the liquid to flow from the container into the input body portion. The output body portion has an output aperture communicating with the flowing diluent. An input one-way valve is disposed in the input aperture for permitting the flow of liquid only from the container to the pumping chamber whereas an output one-way valve is disposed in the output aperture for permitting the flow of liquid only from the pumping chamber. A motive device reciprocates the output body portion relative to the input body portion between a first and a second position for causing liquid to flow from the container through the input one-way valve into the pumping chamber when the output body portion is moved into the first position and for causing liquid to flow from the pumping chamber through the output one-way valve to mix with the diluent when the output body portion is moved into the second position.

Abstract: A device for use in the control of mechanical forces. The device comprises first and second terminals for connection, in use, to components in a system for controlling mechanical forces and independently moveable. Hydraulic means are connected between the terminals and contain a liquid, the hydraulic means configured, in 4 use, to produce upon relative movement of the terminals, a liquid flow along at least two flow paths. The liquid flow along a first flow path generates a damping force proportional to the velocity of the liquid flow along the first flow path, and the liquid flow along a second flow path generates an inertial force due to the mass of the liquid, the force being substantially proportional to the acceleration of the liquid flow along the second flow path, such that the damping force is equal to the inertial force and controls the mechanical forces at the terminals.

Abstract: A Raman spectrometer including a laser excitation source, edge filters, and detection optics that direct light into a spectrograph. A spectrograph containing a dispersive element and optics that directs various wavelengths of light onto a segmented diffractive MEMS light modulator array.

Abstract: A reflective diffraction grating having grooves and ridges and providing high throughput efficiency in the minus-first diffraction order. All but the zeroth diffraction order and the minus-first diffraction order may be prevented from existence by directing the radiation onto the grating at an appropriate angle. The radiation having a TM polarization is eliminated from the zeroth order by destructive interference by appropriate selection of a the groove width of the grating, and radiation having a TE polarization is eliminated from the zeroth order by destructive interference by depositing an overcoat of an appropriate thickness. A dielectric material may be deposited in the grooves.

Abstract: A diffraction grating providing reduced polarization dependent loss. The elements of pixels of the diffraction grating are fixed or actuated such that some grating elements are actuated to correspond to a positive polarization dependent loss and others are actuated to correspond to a negative polarization dependent loss. The pixels may include multiples of three grating elements or multiples of four grating elements. An electrostatic beam structure providing increased actuation in a direction away from a substrate may be used in a diffraction grating providing reduced polarization dependent loss.

Abstract: A stress sensor having directional measurement capabilities based on the photoelastic effect in isotropic photoelastic materials. Directional measurement capability is achieved in the sensor by the incorporation of three different optical axes passing through the photoelastic element. This creates three independent stress sensors which utilize a single sensing element. Each of the three independent stress sensors are sensitive to applied stress in different directions. The response of each of the sensors is analyzed and the magnitude and direction of incoming stress is determined. The use of a sum-difference output detection scheme results in immunity to light source intensity variations, optical fiber microbending losses, and fiberoptic connector losses. The stress sensor is immune to electromagnetic interference (EMI) and electromagnetic pulse (EMP), and is compatible with fiberoptic data transmission and control lines.
