The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system includes features for adjusting the energy applied to an energy application tool to compensate for the physical characteristics or type of the object, and/or for orientation of the device relative to the horizontal during measurement. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.

The chassis also includes one or more outer walls extended at acute angles with respect to the base face and arranged around the inner perimeter wall. One or more light sources are disposed on the outer walls. The imaging device further comprises a lens, an optical filter, and an optical detector disposed within the interior region. The imaging device further comprises a control system and a low-voltage power source.

We disclose a portable wearable device for measuring electrocardiographic signals, the device comprising a first portion comprising at least two electrodes; a second portion comprising at least three electrodes; the first portion and the second portion being vertically spaced from one another; a controller configured to take: a first potential difference measurement using one of the electrodes of the first portion and one of the electrodes of the second portion; a second potential difference measurement using one other of the electrodes of the first portion and one other of the electrodes of the second portion; and a third potential difference measurement using one other of the electrodes of the first portion and one other of the electrodes of the second portion. The controller is configured to simultaneously take the first, second and third potential difference measurements at three independent positions of a user's body.

A method of screening a pupil of a subject to determine whether the pupil reflex resembles a canonical pupil reflex is disclosed. The method comprises the steps of stimulating the pupil with a stimulus source, such as a pupilometer and determining whether one of various pupillary response conditions is met.

A device includes a main body having a length, a first end, a second end, and an axis along the length. A first electrode is associated with the first end of the main body. A suspension structure is associated with the second end of the main body. The suspension structure is configured for displacement in a direction of the axis of the main body, and includes a flexible isolation ring defining an opening, and a second electrode that is associated with the opening and mechanically coupled to the flexible isolation ring. The device also includes an electronics assembly with a first subassembly that is electrically coupled to the first electrode and secured relative to the main body to prevent displacement of the first subassembly in a direction of the axis of the main body, a second subassembly that is arranged to electrically couple with the second electrode. A flexible coupling between the first subassembly and the second subassembly enables displacement of the second subassembly relative to the first subassembly and in a direction of the axis of the main body.

The present application provides a personal hand-held monitor for the measurement of a subject's blood pressure and, optionally, one or more other vital signs, comprising a housing located on a personal hand-held computing device or a hand-held component of a computing system; a blood flow occlusion means located in the housing; a pressure sensor adapted to provide an electrical signal indicative of the pressure applied; a means for detecting the flow of blood in the body part of the subject when pressure is applied; and means for receiving electrical signals from the pressure sensor and the blood flow detecting means and for transmitting electrical signals indicative of the pressure and blood flow to the processor of the personal hand-held computing device or the computing system, wherein the processor of the personal hand-held computing device or computing system provide at least a measurement of the blood pressure of a subject. The processor is further adapted to carry out a process to measure a diastolic blood pressure value and a systolic blood pressure value.

A device and a method used for self-detection of eye opacities. The novel device utilizes a light source, which illuminates an orifice, to self-detect, measure, and locate an opacity's shadow projected on the retina using a grid sheet. This device monitors the early onset of eye disorders, such as cataracts, as well as post-operative detection of opacities after cataract surgery or capsulotomy. It is also portable, inexpensive, and does not require special training to utilize it.

A sleeve or sheath includes a body having a top opening. The body covers a handheld oximeter probe or a portion of the probe. The sleeve has a shape that approximately matches the oximeter probe or portion of the probe, which is covered by the sleeve. The sleeve has a top opening that allows a user to slide the oximeter probe into the sleeve. The sleeve is transparent to radiation emitted and collected by the oximeter probe. The sleeve is formed of a material that prevents patient tissue, fluid, viruses, bacteria, and fungus from contacting the covered portions of the oximeter probe. The sleeve leaves the probe relatively sterile after use so that little or no clearing of the probe is required for a subsequent use, such as when the probe is covered with a new, unused sleeve.

An injector for transcutaneously introducing a sensor into a patient, including a cannula, a base element, a sliding element arranged displaceably on the base element, for transcutaneously introducing the cannula into the patient in an injection direction, and including an ejection element for automatically pulling the cannula out of the patient counter to the injection direction by the ejection element in an ejection operation. The injector has a locking element for the ejection element such that, in a delivery state, the ejection element is lockable in an energy-charged state, and the sliding element and the locking element are configured to interact indirectly or directly in order, in an injection state, when the cannula is introduced transcutaneously into the patient, to release the locking of the ejection element in order automatically to start the ejection operation.

Provided are location devices that identify the location for measuring physiological conditions, methods of operating the device, and computer program products for use with the device. The location device provides improved reliability in measurement data since it consistently provides the location for the measurements. In the context of a location device, an apparatus is provided that includes a structure configured to be attached to the skin of a user and configured to identify a location for physiological measurement. The structure has a shape configured to correspond to a portion of the user that is in a predefined positional relationship to the location for the physiological measurement. As such, the structure is configured to engage the portion of the user in order to identify the location for the physiological measurement. The location device may include one or more sensors for measuring physiological conditions or may work in conjunction with one or more sensors.
