US 2016/0109914 A1 · WEARABLE DEVICE WITHOUT A POWER BUTTON

Abstract

An example of a wearable device, such as a head mounted device, without a power button while still implementing the functions of a typical power button is provided. A sensor may be positioned adjacent to a hinge so as to detect the orientation thereof, such as detecting whether the hinge is in the opened or closed position. The sensor may output a signal that indicates the detected orientation of the hinge to a microcontroller. The microcontroller may then output a signal to a power management integrated circuit that alters the current state of the device. For instance, the signal sent to the power management integrated circuit may power on or off the head mounted device, or place the device in a sleep state. In this regard, the head mounted device is capable of switching between states without the use of a typical power button.

Dependent claims

A system comprising:

a sensor configured to detect an orientation of a device;
one or more processors in communication with the sensor, the one or more processors configured to:
receive a first input from the sensor;
determine, based on the first input, the orientation of the device;
based on the determined orientation, output a corresponding signal;
and
provide, via a safety circuit, interference for the outputted signal when a characteristic of the outputted signal deviates from a predetermined allowable characteristic;
and
a power management circuit in communication with the one or more processors, the power management circuit adapted to receive the corresponding signal from the one or more processors and deliver a predetermined amount of power to the device based on the corresponding signal.
