A display system includes an interface unit, a head worn display in wireless communication with the interface unit, and a first tracker sensor remote from a head of a user and configured to wirelessly sense a head pose and provide first head tracking data to the interface unit. The interface unit is remote from the head worn display. The display system also includes a second tracker sensor associated with the head of the user and configured to provide second head tracking data associated with the head pose to the head worn display. The interface unit is configured to receive the second head tracking data from the head worn display via at least one wireless link and provide video information for display on the head worn display via the at least one wireless link.

Monitoring devices and monitoring technology are disclosed for a number of applications. A monitoring device that attaches to a measurement site includes at least one of an optical sensor, a temperature sensor, or first and second electrical contact sensors. A monitoring device or a smart garment can be powered by one or more bio-batteries that is each formed by electrodes in contact with the user's body (e.g., skin) or an animal. Various method and algorithms can be used to process signals received from the optical sensor, a temperature sensor, and/or first and second electrical contact sensors. The signals received from the optical sensor, a temperature sensor, and/or first and second electrical contact sensors can be transmitted to a host device. An application program on a host device can process the signals to compute one or more physiological parameters, waveform data, trend data, and/or one or more reports.

A system and method simplify a Head Mounted Display (HMD) design employing an array of individual Transparent Organic Light Emitting Diode (TOLED) (or similar transparent emitter) elements or a group of sub-elements between dual microlens (ML) elements to create a transparent visual display. The ML elements present both the ambient imagery and synthetic TOLED symbology at the user eye. The user side ML array presents the TOLED image at a defined distance (e.g., several feet to infinity) (to prevent near focus eye strain) and the ML array on the subject side of the transparent visual display enables presentation of the ambient scene to the user eye. A spherical topography ensures that the transparent visual display optical path is along the user eye line of sight to optimize optical throughput and image clarity. A pixel pitch of the transparent visual display determines the visual acuity of the overlay.
