Abstract: A system for providing continuous positive air pressure therapy is provided. The system includes a patient interface, a flow generator, a sensor, and a computing device. Wireless transceivers allow wireless communication between the computing device and the flow generator and/or patient interface. Sensor data is communicated to the computing device and a leak determination is made by the computing device based on the sensor data. If a leak is detected, then troubleshooting options for correcting the leak are displayed to the patient on a display of the computing device. The troubleshooting options may be selected based on the sensed data, the type of patient interface, the type of flow generator, or characteristics of the patient using the device.

Abstract: Impact resistant retractable safety barriers are disclosed. An apparatus includes a support member, a flexible elongate member to extend and retract through an opening in the support member, and a stop member including a region to interface with the flexible elongate member. The stop member engages with structure of the support member surrounding the opening to limit a distance with which the flexible elongate member extends through the opening. The stop member cooperates with the structure of the support member to maintain a gap between a surface of the region of the stop member and the structure of the support member. A width of the gap is equal to or greater than a thickness of the flexible elongate member.

Abstract: System and methods for variable annuity financial product illustrations are provided. A computer system generates user interface screen(s) allowing the user to specify information about a variable annuity financial product to be illustrated, and a desired start date for a financial illustration. An illustration server receives the information and desired start date from the computer system. Historical performance data relating to at least one portfolio of the variable annuity financial product is obtained, and the variable annuity financial product is modeled to produce a first illustration for the variable annuity financial product. The variable annuity financial product is also modeled with a benefit associated with the variable annuity financial product, to produce a second illustration for the variable annuity financial product. An illustration report is created, allowing the user to compare performance of the variable annuity financial product during the illustration period with and without the benefit.

Abstract: The invention provides synthetically and recombinantly-derived humanized antibody conjugates and related methods, diagnostic assays, reagents, and kits. In one embodiment, the invention provides humanized antibody conjugates comprising a human immunoglobulin fragment which is bound by a cross-linking functional group to a non-human antibody fragment (e.g., a non-human monoclonal antibody fragment) comprising an antigen-binding amino acid sequence.

Abstract: A gas turbine operational strategy is provided for the optimization of ISO-Day rated performance. The invention is realized by setting the nominal operating line equal to or slightly below the operating limit line, so that ISO full load performance is maximized. Thus, the first stage turbine nozzle throat area is sized such that, without inlet bleed heat addition, and at Base-Load pressure ratio and firing temperature, the compressor operates within its operational limits on a ISO day. As ambient conditions change, levels of inlet bleed heat and firing temperature are controlled and the inlet guide vane angle is set whereby the nominal operating line is equal to or slightly below the operating limit line.

Abstract: A three part edge seal for an integrated circuit semiconductor chip is disclosed. The edge seal includes two separate layers of metal one of which overlays the other in electrical contact. One of the metal layers is in ohmic contact with a highly doped region formed in the planar surface of the semiconductor body. The two metal layers serve as an electrical conductor to distribute power to various portions of the integrated circuit contained in the chip and electrically charge the highly doped region to prevent migration of ions into the active areas of the integrated circuits.

Abstract: A universal interface adaptor circuit (UIAC) for connecting any one of a plurality of either of two general microprocessor types to a peripheral device using the same interface connections to selectively generate and supply either a WRITE ENABLE signal or a READ ENABLE signal to a peripheral device. A first of the two general types of microprocessors is used in multiplexed-bus multiprocessor (MBM) systems and the second of the two general types of microprocessors is used in non-multiplexed-bus microprocessor (NMBM) systems, where the microprocessors used in both the MBM and the NMBM systems each supply three output signals for determining whether the function is a READ or a WRITE function and the time of occurrence of such READ or WRITE function. The UIAC comprises logic array having three input terminals X, Y, and Z for receiving the three output signals from each of the microprocessors employed in either the MBM systems or the NMBM systems.

Abstract: A bond region is provided on an integrated circuit chip wherein the bond region has two or more sets of closely spaced conductors, each of which is electrically connected to a different point of the integrated circuit. During the manufacturing of the device, at the time of assembly of the chip into the package one end of a connector wire may, optionally, be bonded to the bond region thereby effecting a multiple connection of these different points of the integrated circuit. Such a procedure will enable a specific mode of operation of a multi-mode device.
