Abstract: A wearable iontophoresis system includes a control housing having a connector and an iontophoretic drug delivery patch for placement against the skin of a patient. The patch has a device for retaining the control housing connector which permits the connector to be removably attached to the patch. The control housing also has at least a power supply device and a current delivery device. The control housing has top and bottom surfaces wherein the top surface has raised, recessed and sloping regions. The thickness of the connector is tapered from a second end to a first end. Furthermore, the second end of the connector is attached to the control housing and oriented so that the first end is unattached to the control housing and proximate to the control housing bottom surface. The iontophoretic drug delivery patch includes top and bottom surfaces wherein mounted to the top surface is the device for retaining the control housing connector. The control housing connector retaining device has first and second open ends and a cavity for placement therein of the connector. The taper of the connector permits it to be easily inserted through one of the first and second open ends and into the control housing connector retaining device cavity.

Title: Acetabular cup
Inventor: SWARTS DALE F
IPC: A61F2/30
Filed: 1996-01-31
Abstract: The present invention is directed to an acetabular cup prosthesis for implantation into a pelvic bone. A cup having a cavity for receiving a femoral head is formed of a polymeric material having a predetermined tensile strength. A backing is disposed about and attached to the polymeric cup. The backing has a porous construction defining interstitial pores, with the pores being sized to receive a portion of the polymeric cup therein and adapted for allowing ingrowth of the bone therein.

Inventor: EICK STEPHEN GREGORY
IPC: H04N5/445
Filed: 1996-02-27
Abstract: An apparatus and method for presenting a viewer with an overall representation of the present number of entertainment programs available for selection given one week of program schedule data for 300 or more channels and one or morefiltering criteria to limit the number of items represented in the overall representation. Sequentially applied filters will filter the group of program schedule data items that has at least 100,000 half hour time slots offered by 300 channels each week into a smaller subgroup where individual consideration of each item of the subgroup can be made in a reasonable time. A set top box drives the display of overall representations or results of filtering criteria on a commercial TV set. Once a reasonable sizedsubgroup is obtained, other displays provide specific information of the programofferings of the subgroup. Selection of the filtering criteria and selection from within a subgroup is interactively made by a viewer through the use of a controller that looks and operates very much like a TV remote control. This makes the interaction familiar, easy and predictable.

Title: Apparatus and method for capture detection in a cardiac stimulator
Inventor: HOUSWORTH CRAIG M
IPC: A61N1/368
Filed: 1994-09-08
Abstract: A capture detection circuit for an implantable cardiac stimulator.  A signal detected by an electrode in the heart following delivery of a stimulating pulse is amplified, bandpass and highpass filtered, rectified, integrated over a selected window of time starting at a selected delay after delivery of the stimulating pulse, and applied to two comparators having different reference values. If the integrated signal exceeds the first reference value, the first comparator output goes high.   If the integrated signal exceeds the second reference value, the second comparator goes high.   If both comparators remain low, non-capture is indicated. If the first comparator goes high and the second comparator remains low, capture is indicated. If the second comparator goes high, an intrinsic contraction is indicated. The window of integration can be extended to distinguish capture from intrinsic contraction.

IPC: C12Q1/68
Filed: 1994-10-05
Abstract: Methods to screen for antagonists of steroid IR transcription as mediated by the PR-A isoform of the progesterone receptor are provided. Such cell-based methods include a cell in which PR-A is transcriptionally inactive containing a steroid IR other than PR, PR-A and a reporter vector that includes a promoter which is transcriptionally active in the presence of the steroid IR and an activator of said steroid IR, but is substantially transcriptionally inactive in the presence of PR-A. This cell is contacted with the activator of the steroid IR and a compound to be assayed, and the level of reporter product produced in the cell is measured and compared to the level of reporter product expressed in a similar cellular system absent PR-A as an indication of the potential antagonist activity of the compound being assayed. Also provided are an assay kit, a method of screening PR active compounds as ER antagonists and compounds that inhibit the transcriptional activity of a steroid IR in the presence of PR-A in a cellular context where PR-A is substantially transcriptionally inactive.

Patent CA-2184209-A1 (CA)
Inventor: BRUNO RICHARD FRANK
IPC: G06F13/00
Filed: 1996-08-27
Abstract: Internet access is provided to a multimedia terminal (101, 102, 103, 104) supporting the H.320 protocol through a gateway server (125) that is connected to the Internet. The data stream of the H.320 bearer channel (ISDN phone line or switched 56 kbps facilities) is used for the exchange of data between the accessing terminal and the gateway server, which outputs and receives such data onto and from the Internet, respectively. The gateway server is implemented to function to directly exchange on the H.320 data stream information requests and responsive data in the TCP/IP format used for Internet transport. Alternatively, the gateway server is implemented to function as a proxy to which requests are passed from the terminal over the H.320 data stream, and where function calls are made and locally converted to TCP/IP format for transport onto the Internet. For responsive data received from the Internet, the proxy gateway server removes the TCP/IP formatting and transmits the resultant data back to the terminal over the H.320 data stream.

Title: Narcotic containing aerosol formulation
Inventor: FARR STEPHAN J
IPC: A61K47/06
Filed: 1995-05-10
Abstract: An aerosol formulation is disclosed which is comprised of (and may consist essentially only of) an aerosol propellant and a base form of a narcotic drug selected from the group consisting of fentanyl, sufentanil, and remifentanyl. Such a formulation allows for the drug to be dissolved within the propellant and used within a device which dose not require the use of a lubricant. Formulations are also disclosed which include lubricants, wherein the lubricant and propellant are both either polar or both non-polar. Thus, the lubricant component does not act as a solvent or cosolvent, but rather acts as a lubricant for the valve used for dispersing the formulation to a patient. Typical non-polar propellants include chlorofluorocarbons which are typically used in connection with non-polar lubricants such as saturated vegetable oils, e.g. fractioned coconut oils. Typical polar propellants include hydrofluoroalkanes which are typically used in connection with polar lubricants such as polyethylene glycols.

Patent CA-2201410-A1 (CA)
Inventor: KURTYKA BOGDAN
IPC: G01N21/35
Filed: 1997-04-01
Abstract: In a method of matching a known product with one of a library of known products, training sets of the absorbance spectra of the known products are measured and stored.  The training sets of the known products are used to determine an expanded standard deviation spectrum for each known product wherein the expanded standard deviation spectrum combines the training set of spectra with shift replicated spectra into expanded training sets of spectra.   The absorbance spectrum of the unknown product is measured and the distance of the spectrum of the unknown product from the expanded training sets of spectra is determined by dividing the values of the expanded standard deviation spectra into the difference between the absorbance  spectrum of the unknown product  and the mean spectrum of the training set.
