Title: Integrated waveguide having an internal optical grating
Inventor: JOYNER CHARLES H
IPC: G02B6/136
Filed: 1996-05-23
Abstract: A method for forming an optical grating within a waveguide integrated on a substrate includes the step of depositing on a substrate successive layers of material constituting a waveguide such that the waveguide has a periodically varying width along a portion of its longitudinal axis. The deposition may be accomplished by depositing by selective area epitaxy at least some of the successive layers through a mask having a periodically varying width along at least one edge. The successive layers deposited through the mask may constitute a plurality of quantum well layers separated from each other by barrier layers which collectively form a multiple quantum well stack.

Abstract: A portable, baseball hitting, practise device which will return the ball to its original position after being struck. The device is comprised of a baseball with an elastic cord passing through it with slidable clamps on the cord at each pole of the ball. The clamps allow selective positioning of the ball to accommodate the height of the hitter. The cord is anchored at the bottom by a ground screw or indoors by a screw eye bolt to a base. The cord is attached at the top to a, steel or equivalent, ring on a swing bar which is arched to allow for a striking area and is inserted loosely into a verticle pole, which allows the curved swing bar to swing when the ball is struck, then return to its original position. The verticle pole is welded to a circular plate which is bolted to a base plate and both plates sandwich a rubber-like disc that will absorb the shock of the ball being struck. The base plate is anchored to the ground or base by ground screws or lag bolts.

Filed: 1995-05-11
Abstract: A crystal assembly (1) for optical analyzation of samples includes a first crystal member (5) and a second crystal member (6), the latter of which is preferably a diamond. The first and second crystal members, which have substantially the same index of refraction for infrared energy, are coupled together at an optically transmitting interface. This interface may be formed by crystal surfaces in intimate contact with one another or by a third crystal member (85) positioned therebetween. The first crystal member (5) has at least one circumferential sidewall focusing surface for redirecting infrared energy within the first crystal member (5) to and from a focal ring or focal plane at or near the optical surface. The focused infrared energy transmitted from the first crystal member (5) is internally reflected within the second crystal member (6) to obtain encoding specific to a sample in contact with a surface of the second crystal member (6). The encoded infrared energy is then reflected back into the first crystal member (5) for ultimate transmission to a detector (63).

Title: Sinus preference method and apparatus for cardiac pacemakers
Inventor: STROEBEL JOHN C
IPC: A61N1/368
Filed: 1995-11-13
Abstract: A dual chamber, rate-responsive pacemaker for pacing a patient's heart novelly allows tracking of the patient's sinus rate when the sinus rate is slightly less than the sensor rate; i.e., within a predetermined "Sinus Preference Window Maximum Rate Drop". Pacing at the sensor rate occurs when the sensor rate exceeds the sinus rate by more than the Sinus Preference Window Maximum Rate Drop. In the preferred embodiment a Sinus Preference Window, which occurs at the end of the ventricle-to-atrium interval, is decremented with successive heart beats by a programmable delta to increase the pacing rate until the Sinus Preference Window reaches zero, in which case the pacemaker paces at the sensor rate. The Sinus Preference Window is reset to its maximum value upon either the detection of an atrial sensed event, or upon the expiration of a programmable Sinus Check Interval. The pacemaker paces at the sinus rate or the maximum rate drop rate, whichever is faster, for a number of recovery beats, and then increments the pacing rate up to the sensor rate.

Title: Method for associating data bearing objects with user interface objects
Inventor: UPSON LINUS
IPC: G06F9/44
Filed: 1995-12-07
Abstract: The present method provides objects called association objects (350) that are interposed between a controlling object (340) and each user interface object (360). The association object for a particular kind of user interface object contains code that allows the association object to interact with the specific kind of user interface object. Each association object also presents a standard interface to a controlling object, regardless of the kind of user interface object with which the association object is associated. The association object takes care of any conversion or translation that must be performed to convert a data value sent by the controlling object into an appropriate value that can be displayed by the user interface object.  Accordingly, instead of requiring different interface code for each kind of user interface object used (360), a controlling object (340) requires only a single block of interface code for communicating with all association objects (350).
