Abstract: A wrist-worn device heart-monitoring device is presented. The wrist-worn heart-monitoring device includes a radial tonometer configured to output a pressure signal indicating a pulse pressure wave at a user's wrist, two or more electrodes configured to output an electrical signal indicating a user's heart has been commanded to contract, and a microphone configured to output an audio signal indicating a closing of a user's aortic valve. The wrist-worn heart-monitoring device further includes a pulse transit time monitor configured to calculate a pre-ejection period of the user's heart based on at least the pressure, electrical, and audio signals, and calculate a pulse transit time based on at least the pre-ejection period, the pressure signal, and the electrical signal.

Abstract: A system for transducing arterial pressure includes a one-piece flexible cap configured to fit around a flexible piezo-electric sensor that is configured to alter an internal resistance upon deflection. The flexible cap includes a deflection wall configured to deflect towards the flexible piezo-resistive sensor in proportion to pressure applied by the artery. A pressure-transducing medium is sealed between the one-piece flexible cap and the flexible piezo-resistive sensor, such that deflection of the deflection wall towards the flexible piezo-resistive sensor causes proportional deflection of the flexible piezo-resistive sensor.

Abstract: A wrist-worn pressure sensing device includes a pressure sensor. The wrist-worn pressure sensing device also includes a first strap that sets the position of the pressure sensor on a wearer's wrist and a second strap that engages with the first strap to adjust the overall length of the strap without moving the set position of the pressure sensor on the wearer's wrist.

Abstract: Techniques for ability enhancement are described. Some embodiments provide an ability enhancement facilitator system (“AEFS”) configured to enhance a user's ability to operate or function in a transportation-related context as a pedestrian or a vehicle operator. In one embodiment, the AEFS is configured perform vehicular threat detection based on information received at a road-based device, such as a sensor or processor that is deployed at the side of a road. An example AEFS receives, at a road-based device, information about a first vehicle that is proximate to the road-based device. The AEFS analyzes the received information to determine threat information, such as that the vehicle may collide with the user. The AEFS then informs the user of the determined threat information, such as by transmitting a warning to a wearable device configured to present the warning to the user.

Abstract: The present disclosure provides systems and methods for using two imaging modalities for imaging an object at two different resolutions. For example, the system may utilize a first modality (e.g., ultrasound or electromagnetic radiation) to generate image data at a first resolution. The system may then utilize the other modality to generate image data of portions of interest at a second resolution that is higher than the first resolution. In another embodiment, one imaging modality may be used to resolve an ambiguity, such as ghost images, in image data generated using another imaging modality.

Abstract: Embodiments of the present invention relate to systems, methods and computer storage media for detecting user input in an extended interaction space of a device, such as a handheld device. The method and system allow for utilizing a first sensor of the device sensing in a positive z-axis space of the device to detect a first input, such as a user's non-device-contacting gesture. The method and system also contemplate utilizing a second sensor of the device sensing in a negative z-axis space of the device to detect a second input. Additionally, the method and system contemplate updating a user interface presented on a display in response to detecting the first input by the first sensor in the positive z-axis space and detecting the second input by the second sensor in the negative z-axis space.

Abstract: A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, a display device, and/or a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The hands-free intercom may provide privacy to the user. The hands-free intercom may prevent an eavesdropper from hearing the user's vocal emissions, for example, by canceling the vocal emissions at the eavesdropper's ear. The directional sound emitter may deliver out-of-phase sound to cancel the vocal emissions. The hands-free intercom may also, or instead, cancel ambient noise at the user's ear. The hands-free intercom may measure or predict a filtration of the sound to be canceled and compensate for the filtration when canceling the sound.

Abstract: A method for facilitating physiological data acquisition includes scheduling a medical appointment between a patient and a medical provider. The medical appointment is to be conducted at a medical provider location on an appointment date. The method also includes selecting a medical device configured to acquire physiological data regarding the patient. The method further includes sending, to a fulfillment system, a request to provide the medical device to a patient location prior to the appointment date. The patient location is remote from the medical provider location.

The hands-free intercom may also or instead induce the user to face in a desired orientation. The directional sound emitter and/or the display device may induce the user by explicitly indicating the desired location, by adjusting an apparent source of the audio or video, by changing quality of delivered audio or video based on user position, by producing irritating audio or video, and/or the like.

Abstract: Techniques for ability enhancement are described. Some embodiments provide an ability enhancement facilitator system (“AEFS”) configured to enhance voice conferencing among multiple speakers. Some embodiments of the AEFS enhance voice conferencing by recording, translating and presenting voice conference history information based on speaker-related information, wherein the translation is based on language identification using multiple speech recognizers and GPS information. The AEFS receives data that represents utterances of multiple speakers who are engaging in a voice conference with one another. The AEFS then determines speaker-related information, such as by identifying a current speaker, locating an information item (e.g., an email message, document) associated with the speaker, or the like. The AEFS records conference history information (e.g., a transcript) based on the determined speaker-related information.

Abstract: Techniques for ability enhancement are described. In some embodiments, devices and systems located in a transportation network share threat information with one another, in order to enhance a user's ability to operate or function in a transportation-related context. In one embodiment, a process in a vehicle receives threat information from a remote device, the threat information based on information about objects or conditions proximate to the remote device. The process then determines that the threat information is relevant to the safe operation of the vehicle. Then, the process modifies operation of the vehicle based on the threat information, such as by presenting a message to the operator of the vehicle and/or controlling the vehicle itself.
