Abstract: Embodiments of the present invention relate to a sensor for facilitating detection of a physiological characteristic of a patient. Specifically, one embodiment includes a detector configured to obtain signals from the patient, the signals being indicative of the physiological characteristic and to send the signals to a monitor, and a sensor memory coupled with the sensor and separate from the monitor, the sensor memory storing patient physiological data derived by the monitor from the signals, the patient physiological data being indicative of the physiological characteristic.

Abstract: A mechanism for storing and providing historical physiological data, such as blood oxygen saturation data, for a patient. In particular, the historical physiological data is stored in a storage medium that “travels” with the patient and is accessible wherever the patient is moved. This is achieved by storing the physiological data within a sensor assembly. At the destination site, a monitor or a device capable of interfacing with the sensor electronics can retrieve and display the data. The historical physiological data allows a clinician or medical personnel at the destination site to assess the condition of the patient for the entire time that the patient has been monitored. Various types of physiological data can be stored including, but not limited to, blood oxygen saturation, heart rate, and temperature data. Compression of the data can be performed to enhance the storage capability.

Abstract: A digital, differential signal processor for measuring, digitizing and storing a plurality of analog electrical potentials and for calculating selected potential differentials for display. Each analog, electrical potential is filtered and amplified in a signal conditioner and then its values at successive instants in time are converted to digital data by an analog to digital converter. The digital data that is output by the converter is stored for later recall. A computer calculates each selected differential potential by calculating the numerical difference between the digital data for the two potentials for which the differential is to be determined. The differential, as a function of time, may be displayed in real time or at a later time based upon the stored data. A multiplexer allows one analog to digital converter to process the signals output from a plurality of signal conditioners.

Abstract: A monolithic switching array integrated with control logic on a dielectrically isolated monolithic substrate is provided wherein individual components are constructed in abutment with the oxide walls of the dielectrically isolated wells to form a diffusion/wall interface. As a consequence, area of the wells can be optimally used, and undesired electric fields around the components are minimized, thus allowing for smaller overall chip dimensions as compared with comparable prior art dielectric isolation (d.i.) or junction isolated construction techniques. Moreover, d.i. construction eliminates undesired parasitic devices in a monolithic circuit and allows for improved system accuracy.
