A device for liveness detection is disclosed. The liveness detecting device has a simplest structure that principally comprises a light sensing unit and a signal processing module. Particularly, the signal processing module is configured for having a physiological feature extracting unit and a liveness detecting unit therein. The physiological feature extracting unit is adopted for extracting a first physiological feature from a PPG signal, or extracting a second physiological feature from the PPG signal that has been applied with a signal process. As such, through the first and second physiological features, the liveness detecting unit is able to determine whether a subject is a living body or not. The liveness detecting device does not use any camera unit and iPPG technology, such that the liveness detecting device has advantages of simple structure, low cost and immediately completing liveness detection.

A method for detecting estrus in sows where insemination is carried out when a determination has been made. In a first method images of a rear profile of each sow are analyzed to make a determination from features relating to a shape, size, and/or color of the vulva whether the sow is in estrus. The analysis can use a program where a large number of images showing the vulva area of a plurality of sows known to be in estrus and known not to be in estrus have been previously analyzed to generate data on the previous images to create a program which generates a signal using the data to make the determination. In a second method a boar is confined and brought into close contact with the sows where images and/or sounds of each sow are analyzed to make a determination whether the sow is in estrus.

Systems and methods of assisting a subject to reach a target state of sexual arousal include obtaining input of the target state of the subject; and generating a transcutaneous vibratory output to be applied to a portion of a body of the subject to assist the subject in achieving the target state of sexual arousal, the transcutaneous vibratory output having variable parameters comprising a perceived pitch, a perceived beat, and a perceived intensity wherein the step of generating the transcutaneous vibratory output further comprises the step of modifying the variable parameters to correspond to the target state.

A system and method for thought-based control of sexual stimulation devices using electroencephalography. The system and method involve a training phase and an operation phase. In an embodiment, the training phase comprises placing electrodes on the head of a person, measuring electrical signals produced by the person's brain via the electrodes while the user engages in one or more thought-based training tasks, associating patterns of electrical activity in the person's brain while performing the tasks with controls of the sexual stimulation device. In an embodiment, the operation phase comprises generating control signals for the sexual stimulation device based on the associations when the patterns of electrical activity are detected by the electrodes. In some embodiments, machine learning algorithms are used to detect the patterns of electrical activity and make the associations. In some embodiments, data from other biometric sensors is included in the associations.

The present invention discloses a home infotainment system having function of non-contact imaging-based physiological signal measurement. In the present invention, an image-based physiological signal (IBPS) measuring device is integrated with a television, and is configured for capture at least one image frame of a user who is watching the television. As such, after detecting detects a face portion from the image frame, the IBPS measuring device is able to subsequently extract at least one physiological signal from the face portion. Consequently, after the physiological signal is applied with at least one signal process by a display processor of the television or the IBPS measuring device, physiological indices of the user are hence calculated, and are subsequently applied with data processes of data storing, data transmitting, and/or displaying the physiological indices by a form of graphs, or diagrams, and/or numeric values.

An apparatus and methods for detection of estrus and optimal time for embryo transfer or artificial insemination in animals. An arched polycarbonate housing is attached to an animal. A circuit board is disposed within the housing. A rechargeable battery mounted on the circuit board provides power to the apparatus. A switch mounted on the circuit board is actuated when a breeding behavior occurs. A controller mounted on the circuit board detects actuations of the switch to generate data indicative of breeding behavior. A transmitter transmits data indicative of breeding behavior to a remote receiver.

Disclosed is a system for real-time detection and annunciation of blood associated with menstruation and surgical wounds. The system comprises a real-time, wide area blood detector, communication means for relay of blood detection information, and annunciation means to inform the user of the emanation of blood. Various system embodiments include local and remote as well as covert and non-covert annunciation to users or medical personnel, various forms of real-time blood detection sensors, blood analysis capability, and smart bandage telemetry.

Arousal events can be determined for a user associated with a wearable device, such as a user wearing a wearable computing device including one or more sensors. The one or more sensors may obtain EDA information that may determine a sympathetic nervous system response of the user, which may be responsive to an arousal event or an activation. Detection of events that increase the EDA response may provide information to the user regarding arousal events and provide recommendations to the user to address the arousal events to decrease their response.
