Assembly of harness and sensor substrate plates for monitoring vital signals of a patient is provided. More specifically, the present invention provides a harness, a sensor substrate plate, and related devices for non-invasively monitoring vital signals of a patient. The sensor substrate plate provides removable attachment to the skin of a patient to measure vital signals of the patient. The sensor substrate plate comprises an elongated main body comprising an upper surface and an under surface. The upper surface is configured to removably contact the skin surface of the patient. Further, a plurality of slots on the upper surface of the main body is mechanically and electrically configured to hold sensors or electrodes for monitoring biometric parameters of the patient. The upper surface also includes a first through hole mechanically and electrically configured to hold an electrical connector; and a first end and a second end of the main body.

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.

Provided herein is technology relating to measuring temperature and particularly, but not exclusively, to devices, methods, systems, and kits for doing measuring temperature at high resolution, e.g., in living organisms.

Implantable medical device configured to detect an atrial electric signal of a heart, and a ventricular electric signal of the same heart. Atrial events are evaluated in the atrial electric signal detected by a first detection unit and/or ventricular events are evaluated in the ventricular electric signal detected by a second detection unit for recognizing a condition of the device in which atrial electric signals are insufficiently detected.

Evaluation is done by applying at least one of: morphology of the detected atrial electric signals; lacking stability of atrial events; absence of atrial events over a period of time; an amplitude of the detected atrial electric signal being lower than a predefined threshold value; absence of atrial events during detection of ventricular electric signals simultaneously; comparison of atrial events sensed with first and second sensing profiles, the second being more sensitive than the first.

Described herein are systems and methods for monitoring an animal comprising: an electronic device configured to be implanted within an animal, the electronic device comprising: one or more sensors comprising at least one of an accelerometer, a gyroscope, or a magnetometer, the one or more sensors configured to determine location or movement information relating to the animal; a memory device configured to store the location or movement information relating to the animal; a communication interface configured to wirelessly communicate the location or movement information to an external device; and a battery device for providing power to at least one of the one or more sensors or the communication interface.

A current sensor may take measurements of electrical currents that flow between two limbs of a mammal through at least a portion of the mammal’s torso. The current measurements may be taken during a single diagnostic session while a ground electrode contacts the body at a preferably distal location on a limb and a probe electrode is sequentially placed at different locations on distal portions of other limbs. Each of the current delivery locations may be an acupuncture point. An electrical current state for the diagnostic session may be calculated. This state may consist of current ranges for one or more electrical currents that are measured during the session. A lookup table may be employed to determine one or more medical conditions that are indicated by the current state. Alternatively, a trained machine learning model may predict, based on the measured currents, one or more medical conditions.

A method for identifying causative ailments or conditions for health-related symptoms of an animal. Information from a pet profile database and symptoms are received. First-tier data options are selected by a user and an algorithm analyzes them using information from a medical knowledge database. Data options associated with each successive tier are determined by the algorithm, based on user-selected responses to data options of a prior tier and information from the medical knowledge database, presented and applicable data options selected. The algorithm conducts a statistical analysis of user-selected data options of each tier to determine numerical values indicating a likelihood that an associated ailment or condition is a cause of the symptoms. A machine learning model receives and further refines the numerical values. A report is presented setting forth refined numerical values and the ailment or condition associated with each one of the refined numerical values.

An apparatus for the uninterrupted administration of fluid to an animal body during clean blood collections is disclosed. Embodiments include an intravenous device defining a first fluid channel, wherein the first fluid channel is configured to selectively transport IV fluid to an animal body and draw a bodily fluid from the body, and a connection member configured to connect to a catheter to the first fluid channel and defining a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface is shaped to create a fluid flow pattern that quickly and completely removes residual bodily fluid remaining at the concave distal end. Embodiments include a concave surface defining an asymmetric funnel shape, a vertex of which is centered on the first fluid channel.

Systems, methods and devices are implemented for microscope imaging solutions. One embodiment of the present disclosure is directed toward an epifluorescence microscope. The microscope includes an image capture circuit including an array of optical sensor. An optical arrangement is configured to direct excitation light of less than about 1 mW to a target object in a field of view of that is at least 0.5 mm.sup.2 and to direct epi-fluorescence emission caused by the excitation light to the array of optical sensors. The optical arrangement and array of optical sensors are each sufficiently close to the target object to provide at least 2.5 μm resolution for an image of the field of view.

Systems and methods for improving limited-view photoacoustic tomography using an acoustic reflector are described. In particular, an acoustic reflector and ultrasonic transducer array are integrated to provide a virtual array that enhances the field of view of the ultrasonic transducer array, thereby improving the quality of photoacoustic tomography images obtained using the systems and methods described herein.
