A computer implemented and automated method for detecting and measuring an allergic reaction is described. The method utilizes a server computer, an infrared module, a camera, and electronic devices connected through a network to measure allergic reactions as well as manage a patient's end-to-end allergic treatment.

The infrared (IR) module includes a temperature sensor to detect and read radiation and provide a temperature reading emitted from the wheal formed on patient's body in response to an allergen.

The camera captures an image of the wheal and provides its dimensions.

IR module and camera correlate data to verify accuracy and provide criticality of the reaction.

The method also provides other modules such as vaccination module, scoring module, allergen recommendation module, and a skin test result management module. All modules are provided on an electronic device and allow user input and changes to manage allergy treatment.

The apparatus includes a support frame, a fixation assembly for securing a first body segment of a joint, and a displacement assembly mounted to the support frame. The fixation assembly includes an axis of rotation moveable relative to the support frame. The displacement assembly includes a first frame pivotably mounted to the support frame and rotatably connected to a first end of the fixation assembly, and a second frame pivotably mounted to the support frame and rotatably connected to a second end of the fixation assembly.

Embodiments of the present invention provide an oral device. According to one embodiment of the present invention, a mouthpiece suitable to detachably engage teeth of an upper jaw is provided. The mouthpiece comprises an adhesive layer configured to attach a hermetically sealed chamber to the mouthpiece. The hermitically sealed chamber fits within a concave space created by the mouthpiece. The hermitically sealed chamber comprises two layers and embedded between those two layers are a pressure sensor, a microphone, an optical sensor, a temperature sensor, a communications module, a storage enclosure, and a biosensor. Each of the pressure sensor, the microphone, the optical sensor, the temperature sensor, the communications module, the storage enclosure, and the biosensor are operably connected within the hermetically sealed chamber.

A method for determining a muscle fatigue of a muscle includes the step of electrostimulating the muscle at different frequencies, wherein the electrostimulation includes, at each frequency, a repetition of pulses during a period of time lower than 5 s. The method further includes the steps of determining forces developed by the muscle in response to the electrostimulations of step (i); and determining a muscle fatigue on basis of the determined forces.

An in-ear optical sensor device sits deep within the ear canal of a subject such that is in the cartilaginous region and/or the bony region of the ear canal where effects from temporomandibular joint activity or other movement, and external light, are limited. The device has a lateral housing and a medial articulating head joined at an articulation joint so that the medial articulating head may be angled relative to the lateral housing to help the device fit within tortuous ear canals. The device also includes a seal configured to conform to the shape of the ear canal to physically support the device to further limit movement and block environmental light. An audio receiver is also included in the device.

A biometric information detection device according to one embodiment of the present disclosure is configured to be installed in a living body, and includes a sensor, a battery, a mechanical switch, a sealing member, and a holding member. The mechanical switch switches between a conduction state in which power is supplied from the battery to the sensor and a cutoff state in which supply of the power is blocked. The sealing member seals all of the sensor, the battery, and the mechanical switch. The holding member is attached to the living body and holds the sealing member.

A polymer holder for a biosignal processing device, wherein a wall of the polymer holder forms a pocket, and the wall follows an outer contour of the biosignal processing device. The polymer holder has a first aperture for inserting the biosignal processing device into the pocket and removing the biosignal processing device from the pocket. The polymer holder includes an electrically conductive contact structure, which is in a wired electric contact with electrodes that receive the at least one biosignal, at a rear section opposite to the first aperture, and the electrically conductive contact structure is at least partly attached inside the wall. The electrically conductive contact structure is electrically connected with a counterpart of the biosignal processing device in response to an insert of the biosignal processing device in the pocket.
