The invention provides a magnetic inductive sensing system for sensing electromagnetic signals emitted from a body in response to electromagnetic excitation signals applied to the body. The electromagnetic signals are generated and sensed by the same loop resonator which comprises a single-turn loop antenna and a tuning capacitor. The loop antenna of the resonator and a signal generation means for exciting the resonator to generate excitation signals are together configured so as to optimize the value of a ratio between the radial frequency of the generated electromagnetic excitation signals and a reference frequency of the antenna, where the reference frequency is the frequency for which one wavelength of the generated excitation signals (waves) matches the circumferential length of the antenna. This ratio, which corresponds to a normalized radial frequency of the generated excitation signals, is maintained between a value of 0.025 and 0.50.

A diagnostic cassette includes a substrate, to physically and electrically connect the product to a computing device, a reservoir defined within the substrate to receive a fluid sample for processing by the diagnostic cassette, a reagent to react with the fluid sample deposited in the reservoir to form a solution to enable processing of the fluid sample by the diagnostic cassette, a channel to direct the solution, and a sensor to measure a number of parameters of the solution passing through the channel. A method for measuring microfluidic samples includes receiving, in a reservoir, a fluid sample to be measured, combining the fluid sample with a reagent to create a solution, moving the solution through a channel, and measuring the solution, using sensors, as the solution passes through the channel.

The invention provides a body-worn system that continuously measures pulse oximetry and blood pressure, along with motion, posture, and activity level, from an ambulatory patient. The system features an oximetry probe that comfortably clips to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. Analog versions of these signals pass through a low-profile cable to a wrist-worn transceiver that encloses a processing unit. Also within the wrist-worn transceiver is an accelerometer, a wireless system that sends information through a network to a remote receiver, e.g. a computer located in a central nursing station.

The present disclosure provides a system for active noise cancellation for a subject placed in a scanning bore of a medical imaging apparatus. The system may be directed to perform operations including detecting first noise signals by a first array of noise detection units disposed in the scanning bore, at least part of the first noise signals resulting from an operation of gradient coils of the medical imaging apparatus. The system may also be directed to perform operations including detecting, by a second array of noise detection units, second noise signals near a target position associated with the subject. The system may further be directed to perform operations including determining anti-noise signals based on the first noise signals, the second noise signals and excitation signals used for the operation of the medical imaging apparatus.

The invention provides systems for handling biofluids including the transport, capture, collection, storage, sensing, and/or evaluation of biofluids released by tissue. Systems of some aspects provide a versatile platform for characterization of a broad range of physical and/or chemical biofluid attributes in real time and over clinically relevant timeframes. Systems of some aspects provide for collection and/or analysis of biofluids from conformal, watertight tissue interfaces over time intervals allowing for quantitative temporal and/or volumetric characterization of biofluid release, such as release rates and release volumes.

The present it relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.
