A serial data interface includes a receive data terminal, a received serial data out terminal and an operating power supply terminal. A zero-power receive detector for the serial data interface includes a source for furnishing operating power to the interface. The supply of power from the source is controlled through a microcontroller for switching power to the interface. The microcontroller is coupled between the source and the operating power supply terminal of the interface. A light source portion of an optical isolator is coupled to the receive data terminal, and a light activated switch portion of the optical isolator is coupled to the microcontroller.

Zero power receive detector for serial data interface

A system is provided for adapting one of a number of different types of instruments to a common protocol. Each instrument has a serial input-output (I/O) port, a control for the serial I/O port, and an input for operating power to the instrument. The system includes a different type of housing for each different type of instrument. Each different type of housing includes openings through which selected controls and displays of a respective one of the instruments are accessible. Each different type of housing includes couplers for coupling to a respective type of instrument's serial I/O port, and to a respective type of instrument's operating power input, and a data processing module including a first multiple conductor. Each type of housing includes a complementary second multiple conductor connector for connecting to the first multiple conductor connector when a respective housing is mated to the data processing module.

Glucose test data acquisition and management system

A method and apparatus for verifying the operating accuracy of an instrument (10) for detecting the concentration of a medically significant component of a body fluid. The instrument (10) operates by determining the remission of a reacted chemistry contained on a substrate (106) after the chemistry has reacted with the medically significant component of the body fluid. The instrument (10) includes a radiation source (182), a radiation detector (300) and a pathway (164) from the radiation source (182) to the chemistry (106) and from the chemistry (106) to the radiation detector (300) when the substrate (106) is properly inserted into the instrument (10). The remission of the chemistry (106) determines the radiation detected by the radiation detector (300). The method and apparatus include inserting into the instrument (10) a verification substrate (106) having a known remission, a mechanism for energizing the radiation source (182), detecting with a radiation detector (300) the remission from the verification substrate (106), and displaying on a display (76) associated with the instrument (10) an indication that the known remission was detected by the radiation detector (300).
