Abstract: A method for optimizing data rates for video services to a subscriber that includes receiving an indication of whether incoming video signals to a set-top box corresponding to the subscriber are being recorded, receiving an indication of whether video content corresponding to the video signals being recorded is being simultaneously viewed by the subscriber, and reducing a data rate for storing the video content that is not simultaneously being viewed by the subscriber.

Abstract: Optimizing data rates for video services on a broadband network. Different data rates can be delivered to a subscriber premises depending on the size of the display screen connected to a set-top box, the type of content being requested, or whether there is real-time viewing. Therefore, the data rate can be optimized to maximize the number of video streams that can be delivered to any one subscriber without causing a perceived reduction in video picture quality.

Abstract: A refrigerated merchandiser (10) includes a cabinet (20) defining an interior product display space (100) and a refrigeration unit (50) is disposed in operative association with the interior product display space in a compartment (55) beneath the lower deck (24). An opening in the lower deck provides an air return inlet (102) establishing a flow passage from the interior product display space (100) to the compartment (55) beneath the lower deck. A cover (120) includes a top plate member (122) disposed superadjacent the return air inlet and a downwardly extending peripheral side flange (124) disposed about the periphery of the top plate member (122). A plurality of air intake ports (125) are provided in the peripheral side flange (124). The lower deck (24) has a recessed upper surface (124C) facing the product display space (100). A grille plate (130) extends across the air return inlet.

Abstract: A refrigerated merchandiser (10) includes a cabinet (20) having a top wall (22), a lower wall (24), a rear wall (34), and side walls (36, 38) defining an interior product display space (100) housing a product (110) in a refrigerated environment for consumer selection. A refrigeration unit (50) is disposed in operative association with the interior product display space in a compartment (55) beneath the lower wall (24). A first opening in the lower wall provides an air return inlet (102) establishing a flow passage from the interior product display space (1000 to the compartment (55) beneath the lower wall. A sealing member (58) is disposed between the under surface of the lower wall (24) and the upper surface of the refrigeration unit cassette (50) about the first opening; and a positioning apparatus (150) for raising the refrigeration unit cassette (50) unit into sealing relationship with the lower wall.

Abstract: Hydrogels intended for orthopedic applications, including repair and regeneration of cartilage, bone, joint surfaces and related tissues, must possess greater strength and toughness than hydrogels used in soft tissue repair. A hydrogel formulation is provided which has high strength, toughness, a suitable mechanical modulus and low equilibrium hydration. It may also have controlled porosity or degradation time. It can be made to polymerize in situ with high (“good” to “excellent”) adherence to target tissue or surfaces. A preferred formulation for forming such gels comprises 40 to 80% by weight of a low-molecular weight polar monomer and 30 to 10% of a hydrophilic macromeric crosslinker.

Abstract: Described herein are adhesive polymeric compositions and methods for using the compositions. The composition are adherent to the applied surface. The compositions, in certain embodiments, are biodegradable and biocompatible, and can be designed with selected properties of compliancy and elasticity for different surgical and therapeutic applications. The adherent polymeric compositions comprise a polymerized macromer network and an additive mixed or entangled in the polymerized macromer. The additive is bonded to a surface by at least one covalent bond or by secondary interactions and is not covalently bonded to the polymerized macromer network. Alternatively, the additive is bonded to the surface by at least one covalent bond and is also bonded to the macromer network. The disclosed compositions can be used as an improved barrier, coating or drug delivery system that due to the additive is highly adherent to an applied surface.

Abstract: Gel-forming macromers including at least four polymeric blocks, at least two of which are hydrophobic and at least one of which is hydrophilic, and including a crosslinkable group are provided. The macromers can be covalently crosslinked to form a gel on a tissue surface in vivo. The gels formed from the macromers have a combination of properties including thermosensitivity and lipophilicity, and are useful in a variety of medical applications including drug delivery and tissue coating.

Abstract: An infrared camera is used to detect leakages in a heat exchanger by an imaging process that indicates temperature differences between a heat exchanger and a pressurized gas therein. The temperature differences are created by cooling or heating either the pressurized gas or the heat exchanger, and any leakages are visually observable by the resultant image which is representative of the temperature differences. The process can be accomplished with the use of ambient air rather than the commonly used trace gases which are less desirable because of economical and environmental reasons.

Abstract: A process for recovering optically pure D(+)alpha-phenethylamine which comprises addition of the racemic mixture to a water/acid solution, and as a resolving agent, optically active D(-)mandelic acid. An optically pure D(+)alpha-PEA mandelate salt is formed, crystallized out of solution and washed with water. The salt is broken with sodium hydroxide, or a similar base, and the D(+)PEA liberated is extracted with toluene. The D(+) PEA recovered by vacuum distillation is recovered in high yield, shows high enantiomeric purity.
