Abstract:
A system for measuring nutritional parameters of food items is provided. The system includes a holding cavity. The system further includes a sensor assembly that includes a transmitter antenna and at least one receiver antenna. The transmitter antenna is configured to transmit signals to a food item in the holding cavity. The receiver antenna is configured to receive response signals from the food item. The system includes at least one switch coupled to each antenna. The switch, in a first state, is configured to set the sensor assembly to an electric potential equal to that of the holding cavity. In a second state, the switch is configured to couple the sensor assembly to a power source. The system also includes a processing unit to process the signals received to determine the nutritional parameters of the food item.
Abstract:
Gas sensors are disclosed having an on-board, low-power data processor that uses multivariable gas classification and/or gas quantitation models to perform on-board data processing to resolve two or more gases in a fluid sample. To reduce computational complexity, the gas sensor utilizes low-power-consumption multivariable data analysis algorithms, inputs from available on-board sensors of ambient conditions, inputs representing contextual data, and/or excitation responses of a gas sensing material to select suitable gas classification and/or gas quantitation models. The data processor can then utilize these gas classification and quantitation models, in combination with measured dielectric responses of a gas sensing material of the gas sensor, to determine classifications and/or concentrations of two or more gases in a fluid sample, while consuming substantially less power than would be consumed if a global comprehensive model were used instead. Thus, the data processor is utilized for linear, nonlinear, and non-monotonic multivariate regressions.
Abstract:
A sensor system includes a first sensor to detect environmental conditions of an environment in operational contact with a subject, a second sensor to detect physiological parameters of the subject in operational contact with an asset, and a control unit comprising one or more processors communicatively coupled with the first sensor and the second sensor. The processors receive a first signal from the first sensor indicative of the environmental conditions, and receive a second signal from the second sensor indicative of the physiological parameters of the subject, and determine a relation between the environmental conditions and the physiological parameters based on the first signal and the second signal. The processors determine a responsive action of the asset based on the first signal indicative of the environmental conditions of the environment or the second signal indicative of the physiological parameters of the subject in operational contact with the asset.

Abstract:
The invention is focused toward enhancing a patient's mobility by providing seamless information/data transfer between medical monitoring devices such as a patient monitor, telemetry hubs, or another mobile monitoring system. The information or data, which are transferred among the medical devices include, but are not limited to, patient demographic information, wireless network, or pairing information. A set of wireless sensors (e.g. ECG, NIBP, Temp, SpO2), which are located on a patient's body, are connected wirelessly to a patient monitor, which is not a mobile device. When a clinician needs to move the patient from one location to a another location, the clinician brings the mobile monitor close to the fixed monitor to transfer the patient and wireless network information to the mobile monitor automatically. This enables the transfer of connected on-body wireless sensors from one medical device to another medical device without physically detaching them from a patient's body.
