Abstract: Techniques for detecting a signal quality decrease are disclosed.  A sensor or probe may be used to obtain a plethysmograph or photoplethysmograph (PPG) signal from a subject. A wavelet transform of the signal may be performed and a scalogram may be generated based at least in part on the wavelet transform. One or more characteristics of the scalogram may be determined.    The determined characteristics may include, for example, energy values and energy structural characteristics in a pulse band, a mains hum band, and/or a noise band. Such characteristics may be analyzed to produce signal quality values and associated signal quality trends. One or more signal quality values and signal quality trends may be used to determine if a signal quality decrease has occurred or is likely to occur.

Abstract: Systems and methods make use of a view optimizing assembly having a deflector assembly with critical physical, pneumatic, and optical characteristics that make possible intra-operative defogging, surgical debris deflection, and cleaning of a laparoscope lens during minimally invasive surgery, while also maintaining visualization of the surgical site. The view optimizing assembly can incorporate a quick exchange feature, which makes possible a surgical method for maintaining clear visualization that includes the ability to make a quick exchange of laparoscopes having different operating characteristics (e.g., laparoscopes with different tip angles, lengths, or diameters) entirely on the sterile operating field and without interference with the preexisting surgical set-up on the sterile operating field. The view optimizing assembly integrates with the existing suite of minimally invasive instrumentation.    It does not interfere with the surgical set-up, and it requires minimal change in the process or practice of a surgical operating room (OR) team.

Abstract: Low rise, user friendly latex foams for sealing insulative cavities of a building are provided. The foams may be applied to the interface of the sheathing and the studs within the insulative cavities to reduce air leaks. The latex foams may also be applied to the face of the studs to obtain an additional seal against air infiltration. The foam can be used to affix fiberglass batts, batt flanges, and vapor barriers to the framing without mechanical fasteners.  A tackifier may be added to impart an adhesive quality to the foam. The tacky nature of the foam permits the drywall or vapor barrier to be repositioned without damage. Drywall is held onto the face of the studs by the tacky foam while mechanical fasteners are inserted to permanently affix the drywall to the framing. The compressive nature of the foam permits drywall to be attached without significant bowing or detachment.

Abstract: A round, hot fillable plastic container includes an upper portion defining an opening; a bottom portion; and a main body portion having a plastic sidewall that has a plurality of vacuum panels defined therein. The main body portion has a generally hourglass shape with a central portion that is narrower than upper and lower portions thereof. The hourglass shape optimizes grippability of the container. Grippability is optimized further by the presence of indentations that are formed between columns that define the hourglass shape and pillow portions that are provided for finger support. The indentations permit a consumer to gain finger traction and purchase with respect to the container body, even when a label is positioned between the container body and the user's fingers. The main body portion further has a first groove defined in the upper portion thereof, a second groove defined in the lower portion thereof and a third groove that is defined in the central portion thereof. The grooves provide dimensional stability during handling and when the main body portion is gripped by a consumer.
