A walking support system includes: an information output device (260); a motion detector (220) which detects a motion of a user; a foot landing position detector (230) which detect a foot landing position of the user; a determiner (240) which determines a recommended foot landing position which is a landing position of the feet suitable for stabilizing motions of a gait of the user on the basis of motions of a gait of the user detected by the motion detector, the foot landing position detected by the foot landing position detector, and dynamics; and an output controller (250) which outputs information indicating the recommended foot landing position determined by the determiner to the information output device.

An on-person portable device and/or app that allows for constant location monitoring of dementia patients is disclosed. Such a device and/or app also includes automated communication of facial recognition of persons proximally near such a patient as well as possible generation of certain music in response to patient status and/or location. The patient is provided the device and/or app for handling or wearing, such as a phone or pair of glasses, in order to follow location through GPS monitoring, and a reactive program therein that automatically views another person and provides an identification thereof coupled with a voice modulator within an earpiece or like device for memory stimulation pertaining to loved ones or friends, and the like. The same program may also provide the music response to comments, movement, or any other external stimuli to the subject patient, again, to evoke a memory stimulus, as well.

Disclosed is an apparatus for diagnosing vertigo and balance related ailment using Craniocorpography (CCG) technique. The apparatus includes a helmet adapted to be worn over a head of a patient. The helmet includes a plurality of light emitting diodes (LEDs). Further, the apparatus includes a camera placed directionally above at a vertical distance from the helmet while the helmet is being worn over the head of the patient. The camera is adapted to track movement of the patient when the CCG is performed on the patient. Furthermore, the apparatus includes an interface card adapted to connect the camera. The interface card is adapted to relay images captured by the camera. A computing system in communication with the interface card is also provided. The computing system is adapted to analyze and present at least a plurality of patient alignment parameters based on the images captured by the camera.

The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

Embodiments of the presently-disclosed subject matter include methods and systems for measuring a level of a neurotransmitter in a subject. Embodiments of the present methods comprise displaying a fixation point, a reward target, and a non-reward target, and measuring one or more saccade movement parameters for reward saccades and non-reward saccades. The saccade movement parameters can include velocity, amplitude, reaction time, or a combination thereof. The present methods can further include determining a reward modulation of the subject, the reward modulation being equal to a difference between the reward and the non-reward values for a respective saccade movement parameter. Some embodiments further include identifying the subject as including a deficiency of the neurotransmitter if there is a statistically measurable difference between the reward modulation of the subject and a reference reward modulation and/or if the non-reward and the reward saccade movement parameters are statistically equivalent.

Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

An oral appliance includes: 1) a body defining a channel to accommodate an upper dentition; and 2) a motion sensor. The body includes a front portion defining a recess, and the motion sensor is affixed to the front portion.

A dynamic wake-up alarm is provided-for, including a clock, a contactless biometric sensor, a processor, memory, and a speaker. The processor may be configured to receive a wake-up rule based on at least two wake-up criteria including a time from the clock and data from the biometric sensor, and evaluate whether the criteria are met to activate an alarm.

Numerous aspects of communication devices, methods, and systems are described in this application. One aspect is an apparatus comprising a plurality of energy generators arrangeable on or adjacent skin. Each energy generator of the plurality of energy generators may be operable to output a plurality of different energy types in a signal direction toward the skin. The plurality of energy generators may be operable to communicate with nerves associated with the skin when arranged on or adjacent the skin by outputting an energy signal in the signal direction with one or more energy types of the plurality of different energy types.
