An apparatus for monitoring nutrition, especially fermentation in a rumen of a ruminant, is designed to be orally applied to the ruminant and to stay permanently in the rumen. The apparatus includes: a) at least one sensing unit for sensing a characteristic value of dissolved carbon dioxide in the liquor of rumen and/or reticulum; and b) at least one first communication unit for the wireless communication of data with a respective second communication unit outside the ruminant. The sensing unit includes at least one attenuated total reflectance (ATR) sensor.

The invention provides systems for characterizing a biological sample by analyzing emission of fluorescent light from the biological sample upon excitation and methods for using the same. The system includes a laser source, collection fibers, a demultiplexer and an optical delay device. All references cited herein are incorporated by reference in their entirety as though fully set forth. Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of-ordinary skill in the art in which this invention belongs.

Embodiments herein relate to devices and methods for assessing deep tissue temperature using optical sensing. In an embodiment an optical temperature monitoring device is included having an optical emitter, wherein the optical emitter is configured to emit light at a first wavelength from 100 nm to 2000 nm. The optical temperature monitoring device also includes an optical detector configured to detect incident light. The optical temperature monitoring device can be configured so that the light from the optical emitter propagates at a depth of at least 1 cm through tissue as measured from a surface of the optical temperature monitoring device and back to the optical detector and the incident light detected by the optical detector is used to determine a temperature of the tissue at depths of at least 1 cm as measured from a surface of the optical temperature monitoring device. Other embodiments are also included herein.

Systems and methods for visualizing ablated tissue are disclosed. In some embodiments, a system for imaging tissue comprising: a catheter having a distal end and a proximal end; an inflatable balloon disposed about the distal end of the catheter; and an optical housing extending from the distal end of the catheter into the balloon, the optical housing being configured to position inside the balloon a light source for illuminating a tissue outside the balloon and a camera for imaging the illuminated tissue.

An oximetry device sealed in a sheath directs a user to allow the oximetry device to make oximetry readings at a number of different tissue locations of a patient and average two or more of the oximetry readings by directing the lifts and placements of the oximetry device and sheath to and from the different tissue locations and detecting the lift and placements. The averages are generated and displayed on a display of the device for the oximetry readings if the lifts are made while use directions for the lifts are displayed on a display of the oximetry device. The averages are not generated if the lifts are not made while the user directions for the lifts are not displayed. The averages are simultaneously displayed with the oximetry readings which are instantaneous measurement for patient tissue.

Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

Embodiments herein relate to devices and methods for assessing pulmonary status using optical oxygenation sensing. In an embodiment, an oxygenation monitoring device can be included having a first optical emitter, wherein the first optical emitter can be configured to emit light at a first wavelength from 100 nanometers (nm) to 2000 nm. The oxygenation monitoring device and further include a first optical detector, wherein the first optical detector can be configured to detect incident light. The device can be configured so that emitted light from the first optical emitter propagates through a lung tissue and detected incident light can be used to determine an oxygenation status of the lung tissue. Other embodiments are also included herein.
