Abstract: Methods, apparatus, and computer-readable media are described herein related to recognizing a look up gesture. Level-indication data from at least an accelerometer associated with a wearable computing device (WCD) can be received. The WCD can be worn by a wearer. The WCD can determine whether a head of the wearer is level based on the level-indication data. In response to determining that the head of the wearer is level, the WCD can receive lookup-indication data from at least the accelerometer. The WCD can determine whether the head of the wearer is tilted up based on the lookup-indication data. In response to determining that the head of the wearer is tilted up, the WCD can generate a gesture-recognition trigger, where the gesture-recognition trigger indicates that the head of the wearer has moved up from level.

Abstract: A handling device for samples and reagents to be used in testing in a system. Carriers of samples and reagents are loaded on a platform which detects the presence of, and proper loading of, such carriers. The carriers are moved from the platform by a transporter to a bar code reader for identification. A reagent container is rotated during reading to facilitate identification. The transporter further moves identified reagent carriers to a carousel on which the carriers automatically secured for storage awaiting use in testing. The carousel rotates, and selected reagent containers rotate on the rotating carousel, during storage.

Abstract: A wearable computing device such as a head-mounted display (HMD) may be equipped with a magnetometer for detecting presence and motion of a hand-wearable magnet (HWM). The HMD may analyze magnetic field measurements of the magnetometer to determine when the HWM moves within a threshold distance of the magnetometer, and may thereafter determine one or more patterns of motion of the HWM based the magnetic field measurements. The HMD may operate in a background detection state in order to determine a background magnetic field strength and to monitor for magnetic disturbances from the HWM. Upon occurrence of a trigger event corresponding to magnetic disturbance above a threshold level, the HMD may transition to operating in a gesture detection state in which it analyzes magnetometer measurements for correspondence with known gestures. Upon recognizing a known gesture, the HMD may carry out one or more actions based on the recognized known gesture.

Abstract: Example methods and systems use multiple sensors to determine whether a speaker is speaking. Audio data in an audio-channel speech band detected by a microphone can be received. Vibration data in a vibration-channel speech band representative of vibrations detected by a sensor other than the microphone can be received. The microphone and the sensor can be associated with a head-mountable device (HMD). It is determined whether the audio data is causally related to the vibration data. If the audio data and the vibration data are causally related, an indication can be generated that the audio data contains HMD-wearer speech. Causally related audio and vibration data can be used to increase accuracy of text transcription of the HMD-wearer speech. If the audio data and the vibration data are not causally related, an indication can be generated that the audio data does not contain HMD-wearer speech.

Abstract: This disclosure relates to proximity sensing for wink detection. An illustrative method includes receiving data from a receiver portion of a proximity sensor. The receiver portion is disposed at a side section of a head-mountable device (HMD). When a wearer wears the HMD, the receiver portion is arranged to receive light reflected from an eye area of the wearer, the proximity sensor detects a movement of the eye area, and the data represents the movement. The method includes determining that the data corresponds to a wink gesture. The method also includes selecting a computing action to perform, based on the wink gesture. The method further includes performing the computing action.

Abstract: Example methods and systems activate and deactivate a voice interface based on gaze directions. A computing device can define a range of voice-activation gaze directions and, in some cases, define a range of social-cue gaze directions, where the range of social-cue gaze directions overlaps the range of voice-activation gaze directions. The computing device can determine a gaze direction. The computing device determines whether the gaze direction is within the range of voice-activation gaze directions. In response to determining that the gaze direction is within the range of social-cue directions, the computing device can activate a voice interface. In response to determining that the gaze direction is not within the range of social-cue directions, the computing device can deactivate the voice interface.

Abstract: Disclosed herein is a method and system for providing various alert notifications to individuals. More specifically, the embodiments disclosed herein are directed to obtaining an alert notification from an external source and determining a geographic area associated with the alert notification. Once the geographic area has been determined the methods and systems described determine one or more users in the geographic area that meet one or more alert criteria. An alert notification is then generated and is provided to one or more users in geographic areas that meet the one or more alert criteria.

Abstract: A head-mountable device configured to authenticate a wearer is disclosed. The head-mountable device can receive an indication of an eye gesture from at least one proximity sensor in the head-mountable device configured to generate sensor data indicative of light reflected from an eye area. The head-mountable device can capture biometric information indicative of one or more biometric identifiers of a wearer of the head-mountable device responsive to receiving the indication of the eye gesture. The head-mountable device can authenticate the wearer of the head-mountable device based on a comparison of the captured biometric information and a stored biometric profile.

Abstract: The electronic monetary transfer system uses a 2-Dimensional (2D) barcode. The service provider/inventors serve as a functionary for the transfer of monetary funds within the framework of several environments. One environment is defined as from one personal account holder to another personal account holder via a Smartphone. Another type of environment commonly referred to as point-of-sale (POS), is from one personal account holders Smartphone to a vendor/merchant account holder. The environments defined above don't represent the limits by which a monetary electronic transfer of funds using an electronic 2D barcode symbol will or could take place. The interface is a 2D time sensitive, pseudo-random barcode generated and uploaded to the requester's mobile device via a web-based application and is processed by an infrastructure similar to those used to support the processing of credit, debit and gift cards.

Abstract: The present description discloses systems and methods for changing the state of a device. One embodiment may include a device configured to provide a device in a first state, receive a signal indicative of first angular data of the device, and compare the first angular data to a first threshold. The device may then execute instructions to initiate a timer when the first angular data is greater than the first threshold, receive a signal indicative of a second angular data of the device, and compare the second angular data to a second threshold. When the second angular data is less than the second threshold and the time passed is within a pre-determined time period, the device may execute instructions to transition the device to a second state.
