Patent CA-2180741-A1 (CA)
Title: Temporary medical electrical lead
Inventor: MEHMANESH HORMOZ
IPC: A61N1/05
Filed: 1995-01-20
Abstract: A temporary atrial defibrillation lead featuring a pad fashioned of a pliant bio-compatible material in which three parallel stainless steel defibrillation wire electrodes are mounted. The pad contains holes which expose the electrode wires in a discontin-uous fashion. The three electrode wires are merged into one polyurethane insulated lead body, proximal to the pad. At the proximal end of the lead body a stainless steel connector pin with break away nee-dle is mounted, for percutaneous exterior-ization of the lead pin, in an area separated from the surgical incision. The break away needle can be broken off to make the con-nector pin suitable to patient cable connec-tion. The pad is permanently implanted on the atria and remains implanted after re-moval of the temporary electrode sections. The temporary electrode sections may be removed by gently pulling them at their proximal end. In a preferred embodiment the pad is fashioned of PTFE felt. In an alternate embodiment the pad is fashioned of collagen and is thereby absorbed by the body tissues over time.

Patent CA-2184214-A1 (CA)
Inventor: WU TA-CHIN
IPC: B23B31/103
Filed: 1996-08-27
Abstract: The invention herein relates to a kind of high speed assembly connection structure that consists of a direction screw of a connector head that fits in the direction slot of a direction slot which causes the direction slot to be limited to a specified direction. The set screw of the connector head protrudes into the cambered groove of the handle, which limits the rotation of the handle within a specified range. The entry position notch of the handle holds the direction slot in a specified direction during assembly insertion and the mounting slot of the direction slot enables the tight engagement of the handle after the handle is rotated. Furthermore, in the operation of the aforesaid structure, no additional tools whatsoever are required to accomplish the rapid installation of a desired direction slot, and this among the primary objectives of the invention herein.

Title: Turbomachinery with variable-angle flow guiding vanes
Inventor: HARADA HIDEOMI
IPC: F04D29/46
Filed: 1996-09-05
Abstract: An impeller-driven turbomachinery for use in centrifugal and mixed flow pump overcomes operational difficulties, such as flow separation and generation of surge at low flow rates, often encountered in similar machines of the conventional design. The turbomachinery is provided with variable-angle inlet guide vane and variable-angle diffuser vanes, and the diffuser section is constructed according to a fluid dynamic principle, and the vanes having a wing shape are distributed tangentially so that the diffuser section acts as a centrifugal diffuser.    A convenient operational parameter, chosen from such variables as input current to drive motor, rotational speed or torque of the drive motor,  inlet/exit pressures,  and fluid velocity,  is monitored during the operation by means of sensors strategically attached to parts of the operating system.  Real time changes in the operating parameter is measured and the setting angle of the  inlet  guide  vane  is  adjusted  in  accordance  with  a predetermined relation between inlet flow volume rates and flow angle of the fluid exiting from the impeller so as to maintain the fluctuations in the monitored operating parameter below a threshold value.  If the targeted head value is not produced under this adjustment, the setting angle of the diffuser vanes can also be adjusted based on real time measurements of other operational parameters. If this adjustment fails to produce the targeted head value, then the rotational speed of the impeller can be adjusted to operate the system while avoiding surge and other problems  encountered at  flow rates.   The proposed turbomachinery and method of operations are highly cost-effective  because  the  control  methodology  is  based  on theoretical analysis of the flow pattern which is verified by trials, and it is not necessary to determine the operating characteristics of each production lot of fluid machines, thus saving the cost of software development for different machines.

Title: Brightness adjustment for images using digital scene analysis
Inventor: BOYACK JAMES R
IPC: G06T5/40
Filed: 1996-02-23
Abstract: A system and method for processing a digital image signal which represents an image can be made to optimally map luminance values versus a tonal reproduction capability of a destination application. Specifically, the system includes a device for partitioning the image into blocks, then combining certain blocks into sectors. An average luminance block value is determined for each block and a difference is determined between the maximum and minimum average luminance block values for each sector. If the difference exceeds a predetermined threshold value, then the sector is labeled as an active sector and an average luminance sector values is obtained from maximum and minimum average luminance block values. All weighted counts of active sectors of the image are plotted versus the average luminance sector values in a histogram, then the histogram is shifted via some predetermined criterion so that the average luminance sector values of interest will fall within a destination window corresponding to the tonal reproduction capability of a destination application.

Title: Assembled multi-layer shafts
Inventor: SWARS HELMUT
IPC: B21D26/047
Filed: 1996-02-27
Abstract: A hollow shaft (1) with external functional elements is assembled by radial expansion in given areas in the axial direction. The inner shaft tube (3) in the sections to be expanded is thus plastically deformed, and the external parts in the sections to be expanded are only deformed resiliently. The functional elements are disposed at least partially on multiple functional elements, the sections to be expanded lying between the functional elements.  The invention further concerns a process for producing hollow shafts constructed in this way and a process for producing multiple functional elements, in particular multiple cams. These multiple functional elements are used to produce assembled hollow shafts. The individual functional elements are produced from tubes with profiles corresponding to the functional elements, and are joined to form multiple cams. In the axial direction the non-circular functional elements comprise annular projections which are concentric to the base circle and whose internal diameter is slightly larger than the outer diameter of the shaft tube.
