Abstract: A head-mounted wearable device incorporates a transducer into a nosepiece. Vibrations from the user's speech are transferred through the bridge of the nose and are detected by the transducer to produce an audio signal. In one implementation, a nose plate with a pair of attached nosepieces is mounted to a transducer, such as an accelerometer. The nose plate may be affixed to a front frame of the head-mounted wearable device using a motion limiter mechanism.

Abstract: Described are techniques for improving the functionality of a computing device by regulating the temperature of an energy storage device used to power the computing device. A housing that encloses the energy storage device may include a first portion having a thermal conductivity that exceeds that of a second portion. The first portion may be configured to contact or be positioned proximate to a user's body or other heat-producing object during use. Heat from the user's body or other object may be conducted through the first portion of the housing toward the energy storage device. The less-conductive second portion of the housing may reduce the rate at which heat from the energy storage device is transmitted into the ambient environment. As a result, the temperature of the energy storage device may increase, improving the performance thereof.

Abstract: A head-mounted wearable device incorporates a transducer that operates as a bone conduction (BC) microphone. Vibrations from a user's speech are transferred through the head of the user to the BC microphone. An air conduction (AC) microphone detects sound transferred via air. Signals from the BC microphone and the AC microphone are compared to determine if a common signal is present in both. For example, both signals may have a cross-correlation that exceeds a threshold value. Based on the comparison, voice activity data is generated that indicates the user wearing the device is speaking.

Abstract: A head-mounted wearable device utilizes electronics placed in one or more of a left temple or a right temple. The temples are joined to a front frame using hinges. The hinges provide passageways, slots, or other openings to permit passage of a flexible printed circuit (FPC) within an open core of the hinge. The FPC allows communication between the left temple and the right temple. During motion of the hinge, the FPC may twist such that the ends within the hinge are rotated relative to one another while remaining substantially parallel to one another. The overall length of the FPC passing through the hinge remains substantially unchanged between the hinge being open or closed. The FPC remains protected within the hinge and is minimally displaced, preventing the introduction of a crease in the FPC at a hinge line.

Abstract: A user interface for a head-mounted wearable device provides many functions to a user. Information about whether the device is being worn (donned) or not worn (doffed) may be acquired in several ways. Force sensing resistors in the device may provide output indicative of the pressure associated with wearing the device. Output from a bone conduction (BC) microphone may be analyzed to determine if the device is in use. Piezoelectric BC speakers typically used to present audio output to a wearer provide changes in voltage corresponding to a change in pressure associated with wearing the device. A BC speaker may emit a signal that is detected by the BC microphone, with changes in the signal strength being used to determine if the device is donned or doffed.

Abstract: A head-mounted wearable device provides many functions to a user. The functions may be provided based in part on whether the device is being worn (donned) or not worn (doffed). Force sensing resistors in the device provide output indicative of forces associated with wearing the device. A time series of values indicative of the magnitude of a force may be determined. An increase or decrease in force values measured at different times may indicate that the device has been donned or doffed, respectively. If a subsequent force value does not differ substantially from a previous force value, this may indicate that the device has remained donned or doffed.

Abstract: Described are systems and methods for facilitating communication between a user and other users, services, and so forth. A wearable device, such as a pair of glasses, may be worn and used in conjunction with another user device, such as a smartphone, to support communications between the user and others. Inputs such as motion of the head, orientation of the head, verbal input, and so forth may be used to initiate particular functions on the wearable device, the user device, or with a service. For example, a user may turn their head to the left and speak to send a message to a particular person. A display light in the field of view of the user may illuminate to a particular color that has been previously associated with the particular person. This provides visual feedback to the user about the recipient of the message.

Abstract: A head-mounted wearable device incorporates a channel inset into a front frame. A flexible printed circuit (FPC) is arranged within the channel and allows communication between a left side of the front frame to a right side. Using the FPC, electronics in a left temple attached to the front frame are connected to the electronics in a right temple attached to the front frame. A retention piece is used to maintain the FPC within the channel, provide protection from an external environment, and so forth. The retention piece may comprise an overmold of silicone plastic.
