A film suitable for use in an ophthalmic system is provided. The film may selectively inhibit blue light within the wavelength range of 400 nm to 460 nm to reduce phototoxic light to the eye while maintaining photopic vision, and may be color balanced to allow for the system into which the film is incorporated to be perceived as colorless to a viewer observing and/or using the system. The system may have a photopic and scotopic luminous transmission of 85% or more and a phototoxicity ratio of less than 80%. When used in an ophthalmic system or other system disposed between an observer's eye and a light source, the film may reduce the flux of blue light to the internal structures of the eye while reducing or minimizing dilation of the pupil.

A physical quantity measuring apparatus includes an oscillation drive circuit that forms an oscillation loop together with a physical quantity transducer and excites a drive oscillation of the physical quantity transducer, and a detection circuit that detects an analog detection signal outputted from the physical quantity transducer using a detection circuit first and thence converts the signal that has been detected into a digital signal using an A/D converter to output the digital signal. The oscillation drive circuit has a drive amplitude detection circuit that detects amplitude of the drive oscillation. A voltage level of a reference of the A/D converter included in the detection circuit is controlled on the basis of a detection output signal of the drive amplitude detection circuit.

The device includes at least one electrode having a side surface normal to the input axis. A relatively large proofmass has at least one side surface normal to the input axis and extends along a width of the proofmass. The proofmass is movable against acceleration relative to the at least one electrode due to inertial force along the input axis to obtain a capacitive variation between the at least one electrode and the proofmass. The side surfaces are spaced apart to define a narrow, high-aspect ratio sensing gap which extends along substantially the entire width of the proofmass.

The invention provides a system and method for analyzing and classifying the losses of a photovoltaic array. The system and method compares expected power output and to actual power output and can determine a photovoltaic string, combiner, or inverter is generating less power than expected due to at least one of snow cover, soiling, and inverter clipping. The system and method can then determine an amount of power lost during a period of time the photovoltaic string, combiner, or inverter is experiencing snow cover, soiling, or inverter clipping and determine a value of the amount of power lost during the period of time. Various user interfaces enable a user to view one or more reasons why a PV string, combiner or inverter is generating less power than expected and the value of the amount of power lost.

An improvement in monopulse radar achieves nulling of a single mainlobe jammer and multiple sidelobe jammers while maintaining the angle measurement accuracy of the monopulse ratio by cascading a multiple sidelobe canceller and a mainlobe canceller, and imposing a mainlobe maintenance technique during the sidelobe jammer cancellation process so that the results of the sidelobe jammer cancellation process do not distort the subsequent mainlobe cancellation process. In this manner, the sidelobe jammers and the mainlobe jammer are cancelled sequentially in separate processes.

A method is provided for determining the activity of an enzyme which releases methylumbelliferone (MU) from an MU-containing substrate wherein the enzyme has a pH optimum below the pKa of MU comprising: contacting a sample suspected of containing the enzyme with the MU-containing substrate at a pH suitable for activity of the enzyme to allow release of MU by the enzyme; contacting the sample with light of a wavelength in the range of about 310 nm to about 350 nm; determining fluorescence produced by the released MU, thereby determining the activity of the enzyme. This real time method provides improved diagnostic methods, for example for diseases associated with an abnormal level of activity of a glycosidase. The real time assay also can be used to screen compounds for their ability to modulate enzyme activity using MU-containing substrates.

A low power super regenerative receiver and a method of reducing the power consumption of the low power super regenerative receiver are provided. The super regenerative receiver includes: an oscillator having a start-up time period starting oscillation that varies according to an existence of an input signal; and a power controller supplying power within the start-up time period of the oscillator.

An active medical device able to discriminate between tachycardias of ventricular origin and of supra-ventricular origin. Two distinct temporal components (UnipV, BipV) are obtained corresponding to two EGM signals of ventricular electrograms. The diagnosis operates in at least two-dimensional space to determine, from the variations of one temporal component as a function of the other temporal component, a 2D characteristic representative of a heart beat and, this, for a reference beat collected in Sinus Rhythm (SR) in the absence of tachycardia episodes, and for a heart beat in Tachycardia. The discrimination of the tachycardia type, VT or SVT, is then realized by a classifier operating a comparison of the two current and reference 2D characteristics.

The lower electrode is disposed on the substrate and is electrically connected to the integrated circuit. The photoelectric conversion layer is disposed on the lower electrode and has a submicron structure therein. The transparent upper electrode is disposed on the photoelectric conversion layer.

A hygienic glove having multiple removable layers. Each outer and successive layer has a tab means, whereby the outer and successive layers can be readily torn off or removed from the remainder of the glove, leaving the remaining layers, and finally the last layer, in place on the wearer's hand.

A glucose sensor for intravascular measurement of glucose concentration wherein the sensor is arranged to measure glucose concentration by monitoring the lifetime of the fluorophore, the sensor comprising:—an indicator system comprising a receptor for selectively binding to glucose and a fluorophore associated with said receptor, wherein the fluorophore has a life-time of less than 100 ns;—a light source;—an optical fibre arranged to direct light from the light source onto the indicator system; —a detector arranged to receive fluorescent light emitted from the indicator system; and—a signal processor arranged to determine information related to a fluorescence lifetime of the fluorophore based on at least the output signal of the detector.

An ambidextrous or hand specific glove with a widened cuff area to aid in donning or doffing the glove is disclosed, together with a former for fabricating the glove and a method of fabricating the same. The glove may further include a bead on the cuff to resist tearing when the glove is put on or taken off. The glove may be fabricated on a continuous, automated chain machine or a batch or semi-batch machine. While the cuff region on the former for fabricating the glove is elliptical in cross-section and is flared, the region of the former on which the end of the glove is fabricated is circular in cross-section and thus allows the beading process to be successfully undertaken. The thumb region and finger regions of the glove may each be provided with a flexible hinge region that enables a user to more easily bend their thumb and fingers.
