An example electronic device may include a first housing 102), a second housing (104), a hinge (106) to pivotally connect the first housing and the second housing between a first orientation and a second orientation, a hinge lock mechanism (108) to lock the hinge in the first orientation, a sensor (110), and a processor (112). Locking the hinge may restrain movement of the first housing relative to the second housing. During operation, the processor may receive, via the sensor, authentication information associated with a user. In response to authenticating the user based on the authentication information, the processor may generate an unlock signal to the hinge lock mechanism to unlock the hinge. Unlocking the hinge may enable movement of the first housing relative to the second housing from the first orientation to the second orientation.

Abstract

For each facial image of a wearer of a head-mountable display (HMD), preprocessed facial images corresponding to combinations of preprocessing parameters are generated. A machine learning model is applied to each preprocessed facial image to predict facial action units. The facial action units predicted from each preprocessed facial image are retargeted onto an avatar to render an avatar facial image. Avatar facial landmarks within each avatar facial image and wearer facial landmarks within each facial image are detected. The combination of preprocessing parameters yielding a highest similarity between the avatar facial landmarks and the wearer facial landmarks corresponding to the avatar facial landmarks is selected.

Abstract

For each avatar, testing images are rendered for different facial expressions that each have ground truth facial action units. An instance of a machine learning model is applied to the testing images to generate predicted facial action units for each testing image. A predictive performance of the instance is calculated for each avatar based on the predicted and ground truth facial action units for the testing images of the avatar. A first set of features common to the avatars for which the predictive performance was better than a first threshold, and a second set of features common to the avatars for which the predictive performance was worse than a second threshold, are identified. The features present only in the second set are identified, as difference features. New avatars having the difference features are generated.

A cleaning device includes a contact member that contacts a rotation surface and a lever device which displaces the contact member. The lever device includes a roller which contacts the rotation surface and a lever which supports the roller to rotate in response to a forward rotation of the rotation surface. The lever is displaced by receiving a force of the rotation surface through the roller and separates the contact member from the rotation surface, in response to a backward rotation of the rotation surface.

Abstract

A bicep muscle electromyographic (EMG) value is received from a bicep muscle EMG sensor and a tricep muscle EMG value is received from a tricep muscle EMG sensor. An intended flexion or extension angle of a forearm relative to an upper arm is calculated based on the bicep and tricep muscle EMG values. An arm avatar is rendered according to the intended flexion or extension angle of the forearm.

Abstract

An anisotropic coating composition can be combined with a dielectric layer to make a coated dielectric layer. In some examples, a coated dielectric layer can include a layer of solid dielectric material and an anisotropic coating layer adhered to the layer of solid dielectric material. The anisotropic coating layer can include a polymer matrix and electrically conductive ferromagnetic particles embedded in the polymer matrix. The electrically conductive ferromagnetic particles can be aligned in a plurality of conductive paths that are spaced apart throughout the anisotropic coating layer and that extend through a thickness of the anisotropic coating layer.
