A system is provided for monitoring analyte in a host, including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor. In one embodiment, the device includes a single point analyte monitor, from which it obtains an analyte value, and is configured to display only single point analyte measurement values, and not any analyte measurement values associated with data received from the continuous analyte sensor. Instead, data received from the continuous analyte sensor is used to provide alarms to the user when the analyte concentration and/or the rate of change of analyte concentration, as measured by the continuous analyte sensor, is above or below a predetermined range. Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. In another embodiment, the device provides for toggling between two modes, with one mode that allows for display of glucose concentration values associated with the continuous glucose sensor and a second mode that prevents the display of glucose concentration values associated with the continuous glucose sensor.

A smart object may be used to monitor physiological parameters of a user. The object has at least one capacitive sensor to sense a change in capacitance when a tissue of the user comes into contact with the at least one capacitive sensor. The change in capacitance can be used to detect physiological parameters of a user such as heart rate, inter-beat interval and respiratory rate. The smart object may also be used with another smart object to determine the identity of the user or other physiological parameters of the user such as blood pressure.

A Wearable Cardiac Defibrillator (WCD) system is configured to be worn by a patient who carries a mobile communication device. The mobile communication device has a user interface that is configured to enable the patient to enter wireless inputs. The WCD system includes a communication module that is configured to establish a local comlink with the mobile communication device. The WCD system also includes a tethered action unit that has a user interface configured to enable the patient to enter action inputs. The WCD system can perform some of its functions in response to the action inputs or to the wireless inputs. Since the wireless inputs can be provided from the mobile communication device instead of the action unit, the patient is less likely to attract attention when entering them, and thus exhibit better compliance.

A method for establishing wireless communications connections between sensors and a computing apparatus of a motion tracking system include the steps: processing radiofrequency signals received by the computing apparatus and transmitted by each sensor, each radiofrequency signal including an advertisement package of the respective sensor; providing a number of RSSI per sensor based on the processed radiofrequency signals; computing and storing mean RSSI values based on the number of RSSI so that a number of RSSImean values is computed per sensor; computing velocities of change of RSSImean, vRSSI, based on the number of RSSImean values so that a number of vRSSI values is computed per sensor; establishing the wireless communications for which at least the following is fulfilled: the computing apparatus determines that at least some vRSSI values within a first period of the number of vRSSI values of each sensor has a modulus greater than a predetermined minimum velocity.

The user associated control device is configured to detect abnormal ECG in the at least one ECG recording. The user associated control device is configured to present an alarm by said indicator means in response to detecting at least one abnormal ECG. The measurement frequency of the sensor array is set based on any detected abnormal ECG.

A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

Data streams are received from each of the plurality of sensors. These data streams comprise varying values generated by in the sensors and characterize an associated physiological parameter. A parameter score is repeatedly determined for each physiological sensor that is based on whether the varying values for the associated physiological parameter deviate from at least one pre-defined threshold. A patient health index is repeatedly generated by combining each of the determined parameter scores to characterize an overall health of the patient. Data characterizing the patient health index is repeatedly provided. Related apparatus, systems, techniques and articles are also described.

A posture measurement apparatus and method is described. The posture measurement system includes a wearable sensor leader node comprising a UWB transceiver coupled to at least two antennas and one or more wearable sensor follower nodes each comprising a UWB transceiver coupled to one antenna. A first UWB signal is transmitted from the wearable sensor leader node to the one or more wearable follower sensor nodes. A second UWB signal is received by the wearable sensor leader node from each follower sensor node in response to receiving the first UWB signal. A time-of-flight value of a signal transmitted between the wearable leader sensor node and the wearable follower sensor node is determined from the first UWB signal and the second UWB signal. An angle of arrival value is determined from the second UWB signal. The body posture can be determined from the time-of-flight and angle-of-arrival value.

Assembly of harness and sensor substrate plates for monitoring vital signals of a patient is provided. More specifically, the present invention provides a harness, a sensor substrate plate, and related devices for non-invasively monitoring vital signals of a patient. The sensor substrate plate provides removable attachment to the skin of a patient to measure vital signals of the patient. The sensor substrate plate comprises an elongated main body comprising an upper surface and an under surface. The upper surface is configured to removably contact the skin surface of the patient. Further, a plurality of slots on the upper surface of the main body is mechanically and electrically configured to hold sensors or electrodes for monitoring biometric parameters of the patient. The upper surface also includes a first through hole mechanically and electrically configured to hold an electrical connector; and a first end and a second end of the main body.

The technology provides a multi-body earpiece suitable for use as an in-ear sensor system, which can be used for biometrics or a human-computer interface. The multi-body earpiece includes two body elements connected together by a flexure. These components provide at least 3 points of contact along different parts of the outer ear, in which the flexure is tethered to the two bodies and arranged to lock them in place during wear. In addition to having stability from moving while minimizing sound occlusion, this arrangement enables any electrodes for the on-board sensor(s) to remain in contact with the skin of the ear, and provide as many contact points in desired areas as the electronics dictate for the signals of interest.
