Abstract: A combiner lens system includes a lens and a lightguide in stack with the lens. The lightguide carries one or more electrically conductive traces. A detector circuit is electrically coupled to the one or more electrically conductive traces to form an electrical circuit. The detector circuit monitors the electrical circuit for an open circuit or a short circuit and generates an output signal that is indicative of a state of the electrical circuit.

Abstract: In a general aspect, an electronic device can include a first battery cell, a second battery cell, a system power bus and a system load coupled with the system power bus. The device can also include a first bidirectional controller that is operationally coupled between the system power bus and the first battery cell. The first bidirectional controller can be configured to control a charging current and a charging voltage of the first battery cell, control a discharge current of the first battery cell. The device can further include a second bidirectional controller operationally coupled between the system power bus and the second battery cell. The second bidirectional controller can be configured to control a charging current and a charging voltage of the second battery cell, and control a discharge current of the second battery cell.

CPC classification number: H01S5/042 , G02B27/0172
Abstract: The present disclosure relates generally to a device, such as a wearable display device configured with a laser diode driver implementing dynamic voltage control for laser diodes. The laser diodes may include one or more of a red laser diode, a blue laser diode, and a green laser diode. The device may determine a load condition based on a frame to be displayed at the device, and determine a target voltage level for a laser diode operably coupled to the laser diode driver of the device based on the load condition (e.g., an image signal processor (ISP) frame buffer load). The device may generate the target voltage level for the laser diode based on a base voltage level. For example, the device may be configured with a voltage booster operably coupled to the laser diode driver to provide the target voltage level in addition to the base voltage level.
