Abstract: A lightweight portable probe or transducer containing a transmissive or reflective electro-optical emitter and receptor in the infrared spectrum is fitted on a subject's finger or toe. Associated electronics energize and monitor the probe, detect cardio-rhythmic fluctuations therefrom, and process digital data over a prescribed window to produce a non-invasive, qualitative or quantitative measure of the subject's circulation. In accordance with one embodiment of the invention, a simple tri-color LED array is used to indicate the subject's circulation as being normal, reduced, or borderline.

Abstract: The invented non-invasive vital signs monitor is in a flexible, nominally flat planar form having integral gel electrodes, a sticky-back rear surface, an internal flex circuit capable of sensing, recording and playing out several minutes of the most recently acquired ECG waveform data and a front surface that includes an outplay port. The invented non-invasive body composition ‘risk’ monitor includes a measurement device for monitoring one or more variables including body fluid mass, dehydration, respiratory rate, blood pressure, bio-impedance, cardiography such as cardiac output, and body conformation parameters. The risk monitor may be provided in a lightweight carrying case into which the vital signs monitor plugs. Finally, a lightweight portable probe or transducer containing a transmissive or reflective electro-optical emitter and receptor in the infrared spectrum is fitted on a subject's finger or toe.

Abstract: The present invention provides an ophthalmic lens comprised of two lens materials with a gap between them of less than about 5 mm. The gap is formed and maintained by particles on the perimeter of the surfaces of both lens materials. Methods are also provided for creating a gap between two lens materials and for producing an ophthalmic lens with a gap between two lens materials.

Abstract: A pressurised can (1) having a body (2) with an open end, through which a product (5) is inserted into the can, and a cover (3) arranged to cover and seal the open end of the body (2). The can is filled to a predetermined height such that the cover (3) is spaced from the product surface (55) to leave a headspace (7). The can (1) is adapted to minimise the volume of the headspace (7), whilst maximising the height (h) of the headspace (7) at the point at which the can (1) is first opened.

Abstract: A medical, electrically powered thermal cover for fitting predominantly the trunk and head of a person experiencing or potentially experiencing traumatic or cold-exposure hypothermia. The thermal cover encases all of the torso and neck, and portions of other body areas. Heating may be distinctly non-uniform, being applied to the body surface only in special regions where the body's capacity for heat uptake may be relatively high. In sum, the system may monitor deep body core temperature, direct heat to the body core where it may be most needed, and controls therapy over time to restore normothermia.

Abstract: Methods and apparatus (20 ) process noninvasively measured electrical bio-impedence values and perform a technique that indicates whether there exists a change from a homeostatic fluid condition, preferably with respect to blood loss, in mammalian tissue. Analyses can be performed to determine a presence or a change in volume of fluid in an anatomical space of a mammal. A preferred implementation of such technique is embodied in an instrument that carries out a method that may predict an onset of a hemorrhagic shock condition.

Abstract: A machine comprises a compression apparatus and a compression pad. The compression apparatus is capable of generating pressure onto an area of a subject's body. The compression apparatus comprises a cavity having an interior sidewall. The compression pad is disposed between the compression apparatus and the area of the subject's body. The pressure is applied onto the area of the subject's body through the compression pad. The compression pad has a first side and a second side. The second side is intended to be oriented toward the area of the subject's body. The first side is intended to connect to the compression apparatus. A post is located on the first side of the compression pad. The post has an exterior sidewall. The post fits into the cavity, contacts the interior sidewall of the cavity, and is retained in the cavity by friction.

Abstract: An easy open end for a pressurised food container, having an end panel and a conventional aperture score, surrounding the periphery of an aperture through which the contents of the container may be dispensed. A tab is provided to facilitate easy opening of the aperture. The easy open end also includes a vent score, which is arranged to rupture before the main aperture score, to vent the internal pressure in the container, before the container is opened. The end panel and/or tab also defines a shield to prevent the egress of product from the vent opening, when the vent score is severed.

Abstract: Diagnostic instruments, systems and methods for performing measurements on eyes are disclosed. In one embodiment of the instrument, a left ocular is disposed in a portion of a left visual path for the left eye, the left ocular positioned to permit the left eye to view a target, a right ocular is disposed in a portion of a right visual path for the right eye, the right ocular positioned to permit the right eye to view a target. The instrument can also include a wavefront sensor disposed on a translation stage, the wavefront sensor having an optical path to an imaging sensor, the translation stage being movable to position the optical path of the wavefront sensor in alignment with the portion of the left visual path in a first state and in alignment with the portion of the right visual path in a second state. One or more light sources are optionally provided for propagating light along a least part of the left and right visual paths to illuminate the left and right eyes.
