Abstract: An apparatus includes at least one sensor, a connector and a conversion unit. The sensor is coupled to a patient body so as to measure a physiological parameter of the body. The connector coupled to a patient monitor, which measures a value of the physiological parameter by applying a test signal via the connector and measuring a response signal on the connector in response to the test signal. The conversion unit is coupled between the at least one sensor and the connector, and is configured to determine a corrected value of the physiological parameter, to calculate an auxiliary signal that, in combination with the test signal produced by the patient monitor, causes the response signal on the connector to represent the corrected value of the physiological parameter, and to generate and output the auxiliary signal to the connector so as to cause the patient monitor to measure the corrected value.

Abstract: Thermometric apparatus includes at least one body-surface sensor, which is configured to be placed at a location on a body surface of a patient and generates a sensor output that varies according to a body-surface temperature at the location. Analog conversion circuitry is coupled between the at least one body-surface sensor and a connector for coupling to a patient monitor. The circuitry is configured to convert the sensor output into an output resistance across the connector that is indicative of a corrected temperature of the patient.

Abstract: Thermometric apparatus includes one or more temperature sensors, which are configured to provide respective temperature-dependent readings at two or more locations on a surface in a vicinity of a sub-surface heat source. A processing unit is configured to process the readings from the two or more locations so as to determine a temperature of the sub-surface heat source.

Abstract: A thermometric device includes a probe having a membrane configured to be applied to an external surface of a body of a subject and one or more temperature sensors located within the probe in thermal contact with the membrane. A processing unit is configured to receive temperature readings from the one or more temperature sensors, to determine time-dependent parameters of temperature change responsively to the temperature readings, to calculate a local temperature of the body using a function including the time-dependent parameters, and to calculate a core body temperature by correcting for a difference between the core body temperature and the local temperature.
