Title: Grooved phaco-emulsification needle
Inventor: BARRETT GRAHAM DAVID
IPC: A61M1/00
Filed: 1995-08-30
Granted: 2006-08-15
Abstract: A phase-emulsification needle (20) is provided for use with a plastic or elastomeric sleeve (17), the needle having a mid-region portion defining a plurality of outwardly extending projections (24) forming longitudinally-oriented grooves (30) that provide adequate irrigant flow rates to the anterior chamber of the eye, even when the entry wound compresses the sleeve (17) against the outer surface of the needle (20), thereby reducing the risk of collapse of the anterior chamber due to inadequate irrigant flow and reducing the risk of excessive heat transmission to the entry wound.

Abstract: A lighting control and dimming system 10 utilizes a single traveler conductor 28 for transmitting analog data signals corresponding to a particular light intensity level of dimmers DIM 1, DIM 2, DIM 3, DIM 4,  ..., DIM N in a dimmer group.   A predetermined binary data word is retrieved from the read-only memory of a controller 30 that may be remote from the dimmers, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit.  Each dimmer unit includes a microcontroller 78 and read-only memory (EPROM) 60 in which a group of binary numbers are stored.   The analog data signal received by each dimmer is converted to binary and is compared bit-by-bit with each binary number stored in the dimmer  EPROM memory  60.   A serial  bit  comparator  72 produces an enable signal 106 in response to a bit-by-bit identity match between the converted analog data signal and the preset binary number  stored in the dimmer EPROM.          Dimmers enabled by the transmitted analog data signal produce a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.

Abstract: A wearable eyetap camera having the appearance of ordinary eyeglasses yet providing a camera view approximately collinear with an eye of the wearer of the eyeglasses is described. Some embodiments look just like ordinary unifocal eyeglasses, while others have the appearance of bifocal eyeglasses. Because of the wearer's ability to constantly see the world through the apparatus, the apparatus behaves as a true extension of the wearer's mind and body, giving rise to a new awareness of photographic composition at all times, whether shooting or simply imagining the process of shooting. Moreover, the apparatus allows the wearer to alter his or her visual perception of reality, or to allow others to do so and thus establish a new form of communications or shared visual space.

Abstract: Lactose intolerance in humans is due to intestinal lactase deficiency. Lactase is a Sulfur-containing enzyme. A study was undertaken to determine whether lactose tolerance could be restored by Sulfur therapy in patients with lactose intolerance. 17 patients with severe lactose intolerance for an average of 13 years (range 1 to 43 years) were treated with Sublimed Sulfur 200 mg orally twice daily after meals until lactose tolerance was restored.  Sublimed Sulfur was then discontinued. Lactose tolerance was restored after 3 to 5 weeks of treatment with Sublimed Sulfur; the patients subsequently remained symptom-free for diarrhea, abdominal pain and bloating for an average of 26 weeks (range 18 to 62 weeks) on unrestricted intake of milk and milk products. The use of Sublimed Sulfur in the treatment of lactose intolerance resulted in restoration of lactose tolerance in humans.

Abstract: System and method for providing a customer with the ability to obtain temporary voicemail service in the Advanced Intelligent Network (AIN) for the customer's calling line by dialing a call to special access code, without the intervention of a service representative. The call is recognized as a request for an initiation of a temporary voicemail service with respect to the customer's calling line. On the basis of the recognition, an association may be retained between the calling line number and the service switching point serving the calling line number.      This retained association may be used later in the activation of the temporary voicemail service for the calling line number. The call is routed to a rental service interface through which rental information from the caller may be collected. This rental information may be compiled into a rental agreement that is used as the basis for activation of the temporary voicemail service with respect to the caller's calling line number. Confirmation of the activation may be provided to the communication.

Title: Packaging material processing apparatus and method of producing packaging containers

Abstract: An object is to prevent roughening of a rupture surface of a packaging material (12) that is formed upon opening of a spout (21) through application of an external force. There are provided transport means for transporting a layered packaging material (12) that is formed of a paper substrate and resin films and that has a rupture area (52) at a location corresponding to that of opening means; a seal unit for sealing the packaging material (12); and heating means disposed on the upstream side of the seal unit in the transport direction of the packaging material (12) such that the heating means is opposed to an innermost layer of the packaging material (12) in order to heat the packaging material (12). In this case, after being heated and melted, the resin film of the packaging material (12) is gradually cooled. As a result, thermoplastic resin that constitutes the resin film is crystallized and becomes brittle. Accordingly, when an external force is applied by use of the opening means to thereby open the spout (21), the resin film does not stretch. As a result, the packaging material (12) can be easily ruptured, and the rupture surface of the packaging material (12) is prevented from being roughened, because the resin film does not have ruptured and stretched portions coexisting in a mixed manner.
