The present disclosure discloses a method and apparatus for testing vital capacity. The method comprises: measuring a static pressure P.sub.0 of a pressure hole inner cavity of a mobile device; wherein the pressure hole is communicated with the exterior and is purposely disposed on the mobile device or is an already-designed opening; obtaining an air pressure P(t) at each moment by blowing air towards the pressure hole; obtaining an air flow speed v(t) corresponding to each moment according to a correspondence relation formula between the air flow speed v(t) and a pressure differential P(t)−P.sub.0; and obtaining vital capacity Vc of the subject according to a correspondence relationship between a measurement time t and the air flow speed v(t). The technical solution obtains the vital capacity of the subject according to the correspondence relationship between the air flow speed and the measurement time, can effectively improve the vital capacity measurement precision, does not cause damages to related components of the testing apparatus, and is completely different from the solution of using a microphone to measure the vital capacity in the prior art.

A method, device and system are provided for remotely monitoring one or more parameters associated with a grazing animal. The method comprises the steps of: mounting a collar comprising sensor onto a grazing animal; detecting by said sensor movements of the grazing animal or lack thereof; classifying the detected movements into a group of pre-defined activity classes; and based detected movements and their classification into at least one of the pre-defined activity classes, determining at least one of the parameters being monitored.

A respiratory monitoring apparatus comprises at least one motion sensor and a processing device. The at least one motion sensor senses an angular motion of a measured part capable of indicating a respiratory motion, and outputs an angular velocity vector of the measured part; the processing device, connected to the motion sensor, extracts a respiratory angular velocity from the angular velocity vector, and acquires a respiratory wave according to the respiratory angular velocity.

An apparatus for patient position or motion monitoring includes: an energy source configured to emit energy from a first location to a second location, or vice versa, wherein the second location that is moveable relative to the first location in response to a movement by a patient; and a processing unit coupled to receive an input that is based on the emitted energy, and to determine a characteristic associated with the patient based on the input.
