Title: Collagen-synthetic polymer conjugates having controlled fiber size distributions
Inventor: RHEE WOONZA M
IPC: C08H1/00
Filed: 1995-01-12
Abstract: Current commercially available fibrillar collagen compositions tend to have heterogeneous fiber size populations, including very large fibers, which are not conducive to efficient crosslinking using chemical crosslinking agents. The present invention discloses preferred methods for producing collagens having relatively homogeneous, controlled fiber size populations, which are then covalently conjugated to synthetic hydrophilic polymers, such as functionally activated polymeric glycols, to produce collagen-synthetic polymer conjugates having unique physical and chemical characteristics. The resulting conjugates are used to prepare formed implants or injectable formulations for use in a variety of therapeutic applications. Compositions of the conjugates may include additional components, such as pharmaceutically acceptable fluid carriers and/or biologically active molecules such as growth factors or cytokines.

Title: Best server selection in layered cellular radio systems
Inventor: KARLSSON BROR
IPC: H04W36/04
Filed: 1994-06-23
Abstract: A multi-level layered cellular radio architecture serves mobile subscriber stations moving within the system. Best server selection is performed for the mobile stations by assigning within each cell a preference value to each other one of the cells with which is associated by proximity of service area. The strength of the radio signal received by the mobile station from the serving cell as well as the radio channels of associated cells is measured. A decision as to the best serving cell for the mobile station is made based upon both the preference value of the associated cells and the signal strength of their respective radio channels.

Title: Valve assembly for the selective operation of a plurality of parallely connected liquid treatment apparatuses
Inventor: SCHENK RUDOLF
IPC: G05D16/10
Filed: 1995-06-21
Abstract: The valve assembly for the selective operation of a plurality of parallely connected liquid treatment apparatuses in dependence of the total consumption of treated liquid comprises a valve housing having an inlet and three outlets. Two of the three outlets are sequentially controlled  by valve body members which are biased by a spring into a rest position and which are axially displaceable along a valve chamber provided in the interior of the valve housing. In the rest position, the valve body members seal the two controlled outlets against the inlet.          The valve body members are displaceable in the valve chamber against the force of the biasing spring by a pressure difference observed between the outlets and occurring when the water consumption increases. Thereby, the controlled outlets are selectively and sequentially released when a threshold of pressure difference is passed.

Title: Optimization of adaptive filter tap settings for subband acoustic echo cancelers in teleconferencing
Inventor: DIETHORN ERIC JOHN
IPC: H03H21/00
Filed: 1995-11-08
Abstract: A subband acoustic echo canceler for a telecommunications teleconferencing room is equipped with subband adaptive filters and filter taps associated with said subbands. A data store is provided containing a weight list for controlling allocation of the filter taps among the subbands. An optimum tap profile as determined by the weights is a composite of room acoustic impulse response and weighting adjustments based on one or more measures of perceived human acoustic sensitivity experienced by far-end users. An active periodic adjustment of the weights responsive to detection of sibilant energy in the incoming path further improves echo cancellation. Active measurement and updating of the room acoustic impulse response provides further refinement.

Abstract: The invention provides a hardware attachment system for display and shelving units utilizing removable mounting studs which engage through the display panels into slots provided in the hardware. The studs are positioned at any desired location on the panels of the display or shelving unit, and concealed by the hardware when mounted while providing secure engagement of the hardware to the panel. In the preferred embodiment, the stud is inserted through the rear of the panel and projects slightly beyond the front face of the panel when fully inserted so the hardware does not contact the panel. The invention can also be used for affixing abutting sections of the display unit. Thus, the invention allows for the versatile positioning of hardware without detracting from the aesthetic appeal or sacrificing the load bearing capability of the unit.
