US Patent:

20020147390, Oct 10, 2002

Filed:

Dec 20, 2001

Appl. No.:

10/034346

Inventors:

John Markis - Waban MA, US
E. Groener - Acton MA, US
Richard Baker - , US
William Oncay - Whitinsville MA, US
Anthony Marini - Clinton MA, US

International Classification:

A61B005/00

US Classification:

600/301000, 235/375000

Abstract:

A system for gathering, displaying and analyzing vital sign data hospital patient. A handheld computer including a touchscreen and a barcode scanner is linked via a WLAN network to a database server which stores patient data at a central location. The handheld computer includes a browser program for displaying HTML data entry forms transmitted from the database server which the nurse/operator uses to supply vital signs data such as the patient's current temperature, blood pressure, pulse rate, and respiration rate. Further data entry forms allow the entry of body intake and output amounts and the patients weight. A barcode scanner integrated with the handheld computer may be used to read patient and operatior identification values, as well as medication identification values, from printed media. The touchscreen controls allow current vital sign values to be incremented or decremented. A conventional PC secured to the patients room may be used when appropriate to perform the bedside data collection and display functions performed by the handheld device.

Abstract:

The present disclosure presents a circuit, a method, and a system to drive a half-bridge switch using depletion (D) mode compound semiconductor (III-V) switching transistors for a DC-DC converter using at least one driver to drive the switches of the circuit. Also included is at least one charge pump electrically connected to a gate of the transistor, to maintain a voltage that holds the transistor in an off-state. The circuit includes AC coupling capacitors to level shift a voltage and realize fast transistor switching.
