Appl. No.:

7/603502

Inventors:

John M. Stuart - El Toro CA
Michael H. Peterson - Glendale CA

Assignee:

Alcon Surgical, Inc. - Ft. Worth TX

International Classification:

G05D 1620

US Classification:

137102

Abstract:

A pressure control system is disclosed for closely regulating the pressure level of a controlled volume. The system comprises first and second sources, a throttled valve for controlling the flow rate of the fluid between each of the first and second pressure sources and the controlled volume, and a feedback control. The throttled valve comprises a rotationally mounted cam, a housing for receiving the cam and including a chamber, a first port coupled to the first pressure source, a second port coupled to the controlled volume, and a third port coupled to the second pressure source. The cam has first and second cam surface portions for defining corresponding first and second transfer functions of fluid flow through the first and second ports, respectively. First and second metering needles are associated with the first and third ports respectively for throttling the fluid flows therethrough. The first and second metering needles are disposed to engage respectively the first and second cam surface portions.

Assignee:

Mallinckrodt Medical, Inc. - St. Louis MO

International Classification:

A61M 3912
A61M 1604

US Classification:

12820717

Abstract:

A tracheostomy system having a neckplate, a tracheostomy tube having an end adapted for insertion into a patient's breathing passage and an end provided with a trach head for swivel connection to the neckplate and a connection mechanism for swivelly connecting the trach head to the neckplate without deformation of the trach head or neckplate and without thermal processing. The present invention also relates to a method for swivelly connecting a trach head to a neckplate without deformation of the trach head or neckplate and without thermal processing.

Appl. No.:

8/326645

International Classification:

G11C 506
H01L 2302

US Classification:

365 63

Abstract:

An electronic package is disclosed in which a plurality of stacked "same function" IC chips are designed to be used in lieu of a single IC chip, and to fit into a host computer system, in such a way that the system is "unaware" that substitution has been made. Memory packages are of primary interest, but other packages are also feasible, such as packages of FPGA chips. In order to "translate" signals between the host system and the stacked IC chips, it is necessary to include suitable interface circuitry between the host system and the stacked chips. Specific examples are disclosed of a 4 MEG SRAM package containing 4 stacked IC chips each supplying a 1 MEG memory, and of 64 MEG DRAM packages containing 4 stacked IC chips each supplying a 16 MEG memory. The interface circuitry can be provided by a single special purpose IC chip included in the stack, referred to as a VIC chip, which chip provides both buffering and decoding circuitry. Additionally, the VIC chip should provide power supply buffering.
