Remote monitoring of a subject wearing a sports helmet is enabled. In one aspect, an example system includes a safety helmet and a sensor integrated with the helmet for continuously gathering head acceleration force data, the head acceleration force data associated with the head movements of a subject. The system can also include a wireless transceiver coupled to the sensor for transmitting the head acceleration force data and a mobile device for receiving the head acceleration force data from the wireless transceiver. The system can further include a database engine for displaying the head acceleration force data to a user.

A system for assessing the stability of a person relative to a horizontal surface during an assessment session is provided. The system includes a platform having a stage upon which the person stands. A sensing configuration senses when the person is unbalanced on the stage, and conveys this information to a processor. The processor converts this information into meaningful graphics for viewing on a display.

Disclosed is a wearable device including a sensor array having a plurality of sensors each configured to detect a physical change in epidermis of a corresponding body area; and a body motion determination unit configured to determine movement of a body part based on sensing signals from the plurality of sensors, and determine whether the determined movement corresponds to one of at least one next motion which is able to be derived from a current motion state.

A connector (140) is provided with a holding component (141), a support component (148), a terminal (144) electrically connected to a contact of a guide wire (130) held by the holding component (141), and a guide component (147) rotatable around an axial line (130A) of the guide wire (130) with respect to the support component (148). The holding component (141) is provided with a body (150) having an insertion hole (150a) for the guide wire (130) and a holding piece (151) extending along an axial line of the insertion hole (150a) from the body (150) and capable of being elastically deformed inward in a radial direction with respect to the axial line. The guide component (147) has a guide surface (165a) guiding the holding piece (151) inward in the radial direction. The holding component (141) is slid along the axis line of the insertion hole (150a) with respect to the guide component (147), whereby the holding piece abuts on the guide surface (165a) to be elastically deformed inward in the radial direction.

An intravascular sensor device can be used to guide treatment of a diseased blood vessel in the body of a patient. In some examples, the intravascular sensor device includes a pressure sensor and an ultrasound transducer. The intravascular sensor device is used to measure a pressure within the diseased blood vessel and acquire an ultrasound image of the diseased blood vessel. The pressure may be measured during hyperemic blood flow that is caused by a pharmacologic vasodilator drug. The measured pressure can be used to calculate a fractional flow reserve value. The ultrasound image can be used to determine a physical dimension of the blood vessel, such as cross-sectional area. The fractional flow reserve value and physical dimensions of the blood vessel can be used to optimize patient treatment.

A pressure sensor includes a diaphragm having a first principal surface and a second principal surface, a semiconductor chip in which resistors constituting a strain gauge are formed, a first structural body having one end coupled to a center of a second principal surface of the diaphragm and the other end coupled to the other surface of the semiconductor chip, and at least two second structural bodies disposed in two straight lines, orthogonal to each other, that pass through the center of the diaphragm in plan view so as to be disposed separately from the first structural body, and having one ends coupled to the second principal surface and the other ends coupled to the other surface of the semiconductor chip, in which the resistors are formed in regions between the first structural body and the second structural bodies in plan view in the semiconductor chip.

A pressure sensor system with at least two absolute pressure sensors can have an external sensor with a pressure sensitive surface in contact with atmospheric pressure (proximal) and internal sensors each with a pressure sensitive surface in contact with one or more regions at an unknown pressure (distal). The unknown pressure is determined by a means to calculate the difference between the first sensor and the internal sensors.

A motion-sensing floor mat, an assembly of such floor mats, and a monitoring system with such floor mats are provided; wherein the floor mat can be joined with another such floor mat and electrically connected to a monitoring device to form the monitoring system; the monitoring device stores a queue list and a topology matrix and uses a topological algorithm to store the identification tag of each such floor mat detected into the queue list in order, to gradually establish the topology matrix for the floor mats detected; and to thereby obtain the relative positions of the floor mats detected. When any of the floor mats is subjected to pressure (e.g., when someone falls on the floor mat accidentally) and generates a sensing signal, the monitoring device can pinpoint the position of that floor mat (i.e., the location of the fall) rapidly according to the topology matrix.

A wireless circuit includes a housing having at least one opening, and sensor connected to the housing at the opening. The sensor includes a first layer having a first dimension and a second layer having a second dimension shorter than the first dimension. The second layer may be positioned entirely within the housing and a surface of said first layer may be exposed to an exterior of the housing.

A radiological imaging device configured to analyze a limb includes a first module that includes a source configured to emit radiation, a second module that includes a detector configured to receive radiation from the source that has passed through the limb, a control station connected to the first and second modules for controlling movement of the first and second modules and acquiring images from the second module, and a platform having an outer support surface to support the first and second modules. The control station includes a casing and a connecting member that is connected to the casing to attach the platform. The platform is suitable to rotate around an axis approximately parallel to the outer surface.
