Abstract: A device for measuring a resistance includes a comparator. A D-type flip-flop has its D input connected to the output of the comparator and its latch input connected for receiving a pulse signal at a fixed pulse repetition rate. A reference voltage source is connected to a first of the inputs of the comparator and an integrator is coupled between an output of the flip-flop and the second of the two inputs of the comparator. The integrator includes a resistor whereby the integrator develops a voltage at the second input of the comparator that depends on the pulse repetition rate and on the resistance of the resistor. The comparator, the integrator and the flip-flop are connected in a negative feedback loop such that at steady state the voltage developed by the integrator at the second input of the comparator is substantially equal to the reference voltage.

Abstract: A method of screening for possible onset of sepsis in a patient includes providing the patient with a transducer that automatically and periodically measures a first physiological parameter of the patient and transmits a first signal that is encoded with the measured parameter value, and receiving the first signal and automatically comparing the measured parameter value with at least one alarm limit. The first physiological parameter is body temperature, heart rate, respiration rate or a clinical indicator of sepsis. A conditional warning signal is asserted in the event that the measured parameter value bears a predetermined relationship to said alarm limit and an alarm signal is issued in the event that a physiological condition other than the condition that gave rise to the conditional warning signal is indicative of onset of sepsis.
Abstract: A skin patch includes first and second layers of material and a telesensor sandwiched between the first and second layers. The first layer has a coating of skin-compatible adhesive material on its face that is remote from the second layer.

Abstract: Score values representing a user's subjective rating of a condition as recorded using a monitor worn by or secured to the user. The monitor includes a clock for generating a periodic timing signal, a user interface for entering score values and a transducer for prompting the user to enter a score value. A time storage device stores timing information and a data storage device for stores time values and related score values. A controller activates the transducer at times indicated by the timing information. The stored time values and related score values can be read from the data storage device.
