Facial skin analysis methods and systems for improving facial skin conditions using vehicle cameras of vehicles having onboard communication modules. Each vehicle is equipped to analyze the facial skin images over time periods and compare the images to determine skin conditions. Based on the facial skin conditions, a treatment recommendation can be transmitted to a seat occupant. Each vehicle is operatively connected to a facial skin analysis application in a data center. The facial skin analysis application includes a registration module which registers each vehicle. Additionally, a vehicle user may register with the facial skin analysis application to have his/her facial skin analyzed when travelling in any of the plurality of vehicles. The facial skin analysis application is operatively connected to a skin data AI analytics module and data lake and searches a plurality of databases for information related to the facial skin conditions to improve the treatment recommendation.

The instrument drive system is attached directly to the instrument channel of the endoscope assembly. operation of the instrument drive system is proximate to the endoscope assembly and an inputs-controls and a deflection control thereof.

Methods and apparatuses for heart rate detection are described. In one example, a headphones apparatus and method includes emitting a first light in a first light direction directed at a left ear location from a left ear light emitter, and detecting a detected first light at a left ear light detector following interaction of the first light with a left ear tissue. The method includes emitting a second light in a second light direction directed at a right ear location from a right ear light emitter, the right ear location different from the left ear location. The method further includes detecting a detected second light at a right ear light detector following interaction of the second light with a right ear tissue, and estimating a heart rate from the detected first light and the detected second light.

An apparatus for estimating bio-information includes a pulse wave sensor configured to measure a pulse wave signal from an object, for a predetermined period of time, a processor configured to extract DC components of the pulse wave signal measured for the predetermined period of time, normalize the extracted DC components, based on at least one of the extracted DC components of the pulse wave signal measured at a time when a reference force is applied by the object to the pulse wave sensor, and estimate the bio-information, based on the normalized DC components.

A system and/or method for measuring a human ocular parameter comprises a human-wearable face shield which has an eye sensor, a head orientation sensor, and an electronic circuit, and a face shield. The eye sensor comprises a video camera that measures horizontal eye movement, vertical eye movement, pupillometry, and/or eyelid movement. The head orientation sensor measures pitch and/or yaw of the wearer's face. The electronic circuit is response to the eye sensor and the head orientation sensor and measures an ocular parameter such as vestibulo-ocular reflex, ocular saccades, pupillometry, pursuit tracking during visual pursuit, vergence, eye closure, focused position of the eyes, dynamic visual acuity, kinetic visual acuity, virtual retinal stability, retinal image stability, foveal fixation stability, or nystagmus.

The present disclosure provides systems and methods for managing blood glucose in a subject. An insulin delivery cannula may comprise a hollow tube comprising a proximal end and a distal end, wherein the proximal end is in fluid communication with a source of a concentrated insulin or insulin analog formulation of at least about 150 units per milliliter. The distal end may be configured to deliver the concentrated insulin or insulin analog formulation into a subcutaneous space. A continuous amperometric or coulometric glucose sensor may located no more than a pre-determined distance away from the distal end. An insulin pump may be fluidically coupled to the proximal end, and may be attached to the insulin delivery cannula directly or via an intervening tube. The glucose sensor and the insulin delivery cannula may be configured to be inserted into the subcutaneous space simultaneously by a single insertion device.

A system for monitoring gas composition in a surgical cavity during an endoscopic surgical procedure includes an gas recirculation system including a main gas flow circuit for fluid communication with a surgical cavity. The system includes a sensor for monitoring a gas species in a gas flow from a surgical cavity of a patient. The sensor is positioned in a channel branching off from the main gas flow circuit coming from the surgical cavity.

An apparatus includes a base portion, a shaft, a colpotomy cup, and a colpotomy cup actuation assembly. The colpotomy cup is slidably attached along a length of the shaft and is configured to actuate along the shaft between a proximal position and a distal position. The a colpotomy cup actuation assembly is configured to drive the colpotomy cup between a proximal position and a distal position. The colpotomy cup actuation assembly includes an actuating assembly configured to operatively couple with a drive output of a robotic arm. The colpotomy cup actuation assembly further includes an elongated member extending distally from the actuating assembly and terminating into a distal end fixed relative to the colpotomy cup. The actuating assembly is configured to drive movement of the elongated member relative to the elongated shaft to thereby drive movement of the colpotomy cup between the proximal position and the distal position.
