A stroke detection system analyzes images of a person's face over time to detect asymmetric changes in the position of certain reference points that are consistent with sagging or drooping that may be symptomatic of a stroke or TIA. On detecting possible symptoms of a stroke or TIA, the system may alert caregivers or others, and log the event in a database. Identifying stroke symptoms automatically may enable more rapid intervention, and identifying TIA symptoms may enable diagnostic and preventative care to reduce the risk of a future stroke.

The present invention relates to a dispenser comprising: a) a reclosable opening on, or for fitment on and/or around an opening of, a container having a cavity for receiving at least one unit of a product to be dispensed; b) a controller adapted for controlling the opening of the reclosable opening; c) a receiver adapted for receiving a user authentication signal; d) a power source for powering the controller and receiver; and wherein the dispenser only permits the opening of the reclosable opening upon the receiver receiving a user authentication signal. The invention also relates to a dispensing system, method of dispensing and a kit of parts including such a dispenser. The inventions are particularly suited for dispensing pharmaceutical products to only the intended recipient and also to ensure compliance with dosage regimes.

The present invention relates to the field of medical monitoring, and in particular non-contact, video-based monitoring of pulse rate, respiration rate, motion, and oxygen saturation. Systems and methods are described for capturing images of a patient, producing intensity signals from the images, filtering those signals to focus on a physiologic component, and measuring a vital sign from the filtered signals. Examples include flood fill methods and skin tone filtering methods.

An occupant assist apparatus (12) has: a receiving device (121) for receiving an occupant information relating to an occupant of a vehicle; an estimating device (122) for estimating, on the basis of the occupant information, at least one of a desire of the occupant to urinate and a desire of the occupant to defecate in a future than a timing when the occupant information is received; and an executing device (123) for executing an occupant assist on the basis of a result of an estimation by the estimating device.

A system for authorization control and breath testing, comprising a management system unit and an authorization control and breath testing unit, wherein the authorization control and breath testing unit is configured to grant authorization to an individual seeking authorization without having access to any personal identification information about that individual.

Video of one or more people is obtained and analyzed. Heart rate information is determined from the video. The heart rate information is used in mental state analysis. The heart rate information and resulting mental state analysis are correlated to stimuli, such as digital media, which is consumed or with which a person interacts. The heart rate information is used to infer mental states. The inferred mental states are used to output a mood measurement. The mental state analysis, based on the heart rate information, is used to optimize digital media or modify a digital game. Training is employed in the analysis. Machine learning is engaged to facilitate the training.

Mental state data useful for determining mental state information on an individual, such as video of an individual's face, is captured. Additional data that is helpful in determining the mental state information, such as contextual information, is also determined. Intermittent mental state data is interpolated. The data and additional data allow interpretation of individual mental state information. The additional data is tagged to the mental state data. At least some of the mental state data, along with the tagged data, is analyzed to produce further mental state information. A mood measurement is a result of the analysis.

A method and system for monitoring a retail environment by performing video content analysis based on two-dimensional image data and depth data are disclosed. Accuracy in customer actions to provide assistance, change marketing behavior, safety and theft, for example, is increase by analyzing video containing two-dimensional image data and associated depth data. Height data may be obtained from depth data to assist in object detection, object classification (e.g., detection a customer or inventory) and/or event detection.

A magnetic resonance imaging system adaptively and dynamically adjusts color and brightness of illuminators mounted on the inside of a bore in response to a scan sequence used for magnetic resonance imaging or the state of a patient in order to relieve discomfort during magnetic resonance imaging. An illuminator control unit selects and determines optical characteristics of the illuminators in response to a scan sequence or the state of a patient.

A physiological monitoring system is provided. The physiological monitoring system includes a feature extraction device, an identifier, a processor, a physiological sensing device, and a vital-sign detector. The feature extraction device extracts biological information of an object to generate an extraction signal. The identifier receives the extraction signal and verifies an identity of the object according to the extraction signal. The processor receives the extraction signal and obtains at least one biological feature of the user according to the extraction signal. The physiological sensing device senses a physiological feature to generate a bio-signal. The vital-sign detector estimates vital-sign data of the object according to the bio-signal and the at least one biological feature.
