Abstract: A method and system for enrolling speed dial names includes providing speaker dependent templates and associated telephone numbers and providing a penalized garbage model for unrecognized speech. When a request for a new template is received it is determined if the list of speed dial names is full (Step 201) and is not it is determined if that name is too similar (Step 205) to a name already on the speed dial list. If so, that name is rejected but if not it is determined if the speed dial name is too short (Step 302), and if not too short or if the user wants to enter the short name the system asks the user to repeat the speed dial name and if a match it is entered. If not a match the system will swap the first and second utterance and compare to see if a match.

Title: Method for manufacturing one-piece tape tabs for use with disposable absorbent articles
Inventor: GOULAIT DAVID JOSEPH KENNETH
IPC: B31D1/00
Filed: 1995-06-09
Granted: 2000-10-24
Abstract: A method for the manufacture of one-piece tape tabs (40) to be used with disposable absorbent articles (20). The first step is to provide a backing substrate upon which the pressuresensitive adhesive of the tape tab (40) can be applied. Once the backing is provided, the pressure-sensitive adhesive is applied to regions of one side to the backing substrate. The backing substrate is then slit in a direction parallel to the machine direction forming tape tab stock that is preferably fed directly to the taper unit of the absorbent article manufacturing line. The taper unit cuts the tape tab stock comprising the pressuresensitive adhesive into individual tape tabs (40), each having a fixed end and releasable end. The fixed end of each tape (40) is joined to the chassis of an absorbent article (20) by means of mechanically bonding the fixed end to the absorbent article (20). The mechanical bonding not only joins the fixed end of the tape tab (40) to the absorbent article (20), but also forms a region on the outwardly facing surface of the fixed end of the tape tab (40) that acts as a release surface for the pressuresensitive adhesive. In preferred embodiments, an area of the absorbent article (20) adjacent to the fixed end of the tape tab (40) is also subjected to mechanical bonding. The mechanical bonding forms a region on the surface of the absorbent article (20) that acts a release surface for the pressure-sensitive adhesive disposed on the releasable end of each tape tab (40).

Abstract: A method for determining the transverse axis for flexion of a condylar ended bone comprises the steps of: conducting a computer tomographic (CT) scan from the end of the condyles inwardly, transverse to the transverse axis of the limb (or extremity) with the joint flexion plane facing forwardly.  One then selects the CT slice image exhibiting maximum epicondylar width and establishes a line between the epicondyles at the widest  extent.    A  line  is  then  established  joining  the posterior condylar tangents on the CT image.  Measured lines are established from the posterior condylar tangent line at right angles to the said line between said epicondyles; and then the transverse axis of motion as referenced from the transepicondylar line is obtained.
