Health and care are improved through monitoring health markers. In one example a method includes measuring repeatedly at different times a quantity of a biochemical marker in a patient, storing the measurements in a log as entries associated with the patient, analyzing the stored measurements by comparing the quantity of the marker across the plurality of log entries, and determining an illness condition when a recent entry is different from previous log entries, for example when the recent entry is different by more than a threshold or when a baseline level or regular pattern is established from the multiple stored measurements and the recent entry is a change from the baseline by more than a threshold. If a deviation is determined, then an alert condition regarding the patient is determined.

A system provides ultra-wideband (UWB) positioning. The system exchanges ranging signals at a first rate between a UWB beacon and a UWB tag. The system then determines movement or location information of the UWB tag; and select, based on the movement or location information, a second rate for exchanging subsequent ranging signals between the UWB beacon and the UWB tag. The system then exchanges the subsequent ranging signals at the second rate between the UWB beacon and the UWB tag.

Embodiments are disclosed for a method for restoring a wearable biological sensor. The method includes determining that a wearable biological marker sensor comprising a reference electrode is placed within a restoration apparatus. The restoration apparatus includes a correct reference electrode, a counter electrode, and a chloride solution. The reference electrode is in electrical contact with the correct reference electrode and the counter electrode through the chloride solution. The method additionally includes determining whether the reference electrode is degraded based on a voltage differential between the reference electrode and the correct reference electrode. The method also includes restoring the reference electrode, if the reference electrode is degraded, by applying a voltage to a circuit. The circuit includes the reference electrode and the counter electrode. Further, multiple chloride ions of the chloride solution bond with a plurality of silver atoms of the reference electrode.
