A fluid dispensing device includes a cartridge comprising a housing and a head coupled to the housing. The housing forms a first chamber configured to accommodate a fluid; and the head includes a nozzle; and an elastomeric wall that is spaced from the nozzle to form a holding chamber. The holding chamber is in fluid communication with the first chamber and configured to accommodate a portion of the fluid; and the nozzle forms one or more openings to eject the portion of the fluid from the holding chamber. The one or more openings form an oblong shape such that a length of the oblong shape is greater than a width of the oblong shape. The one or more openings can include two parallel slots that together form the oblong shape.

Systems and methods for detecting alertness of an occupant of a vehicle

Exemplary embodiments described in this disclosure are generally directed to systems and methods for detecting alertness of a driver of a vehicle. In one exemplary method, a driver alertness detection system determines whether a driver of a vehicle is susceptible to lagophthalmos. If the driver is susceptible to lagophthalmos, the driver alertness detection system may evaluate an alertness state of the driver by disregarding an eyelid status of the driver and monitoring biometrics of the driver such as, a heart rate and/or a breathing pattern. Alternatively, the driver alertness detection system may evaluate an alertness state of the driver by placing a higher priority on the biometrics of the driver than on the eyelid status. However, if the driver is not susceptible to lagophthalmos, the driver alertness detection system evaluates the alertness state by placing a higher priority on the eyelid status than on the biometrics of the driver.

METHOD FOR DELIVERING THE FLUID FORMULATION AS A SPRAY OR A JET OF DROPLETS TO A TARGET AREA ON AN EYE

A package (1) for a fluid formulation (2) to be delivered as a spray or a jet of droplets to an eye (4), comprising an enclosed container (5) a storage recess (6) containing a fluid formulation (2); and a delivery recess (7), adjacent to the storage recess (6). The storage recess (6) and the delivery recess (7) are separated by a fluid barrier (8). Package (1) further comprises a matrix of holes (9), for generating the spray and/or jet of droplets, the matrix of holes (9) opening into the delivery recess (7). The storage recess (6) is configured to expel, by application of an impulse thereto, a dose of fluid formulation (2). The matrix of holes (9) is configured to steer the spray and/or jet of droplets to the target area (3) on the eye (4). Also provided is a device (20) for delivery of the fluid formulation, and a method for delivering the fluid formulation (2) as a spray or a jet of droplets to an eye (4) of a user.

Drowsiness estimating device, drowsiness estimating method, and drowsiness estimating program recording medium
11589787 · 2023-02-28 · ·

This drowsiness estimating device estimates a subject's drowsiness from a time-series signal of the subject's eye-openness width. A filtering circuitry filters the time-series signal of the eye-openness width to eliminate signal changes due to the subject blanking and outputs the filtered time-series signal of eye-openness. A feature calculator calculates a feature from at least the filtered time-series signal of the eye-openness width. A drowsiness estimator estimates a drowsiness evaluated value from the feature and outputs an estimated result. The feature calculator includes at least a first feature calculation circuit that calculates a variation of the filtered time-series signal of the eye-openness width within a feature calculation window width and outputs the variation as a first feature.

Mobile terminal, fragrance generation device, server, fragrance determination method, and program

A fragrance suitable for a user can be provided. A mobile terminal includes: an acquisition unit that acquires a psychosomatic state from a physiological index of a user; an input unit that inputs future information of the user; a determination unit that determines a recipe including one or more types and a mixing ratio of one or more perfumes based on the psychosomatic state and the future information; and a communication unit that transmits the recipe to a fragrance generation device.

NON-CONTACT SYSTEMS AND METHODS FOR MONITORING AND ADDRESSING BREATHING EVENTS IN NEONATES
20230095345 · 2023-03-30 ·

System and methods for video-based neonatal patient monitoring are described. Methods for neonatal patient monitoring can generally include use of a non-contact detector, such as a depth-sensing camera, to obtain data pertaining to the neonate that can then be used to calculate or otherwise determine a neonate patient breathing parameter, such as respiratory volume. The method further includes monitoring the breathing parameter to identify the occurrence of a neonate breathing event, such as apnea, and initiating a neonate stimulation event when a breathing event is identified. The stimulation event can include, e.g., vibration, auditory signals, visual signals, and/or other types of tactile signals. The systems and methods can use additional monitoring apparatus to monitor additional neonate health parameters, and incorporate this additional information into the decision of when a stimulation event should be initiated.
