Abstract: A biodegradable device for facilitating healing of structural voids in bone, cartilage as well as soft tissue is disclosed in the most preferred form including a porous macrostructure made from a biodegradable polymer and a chemotactic ground substance in the form of an RGD attachment moiety of fibronectin formed as a porous microstructure. For repair of articular cartilage, harvested precursor cells are secured to the biodegradable carrier which is shaped for press fitting into the articular cartilage lesion. In the most preferred form, the chemotactic ground substance enhances the attractiveness of the biodegradable device for cellular attachment at the site of repair and also facilitates the attachment of free, precursor cells such as chondrocytes and bone marrow to the biodegradable device.

Abstract: An anatomically specific, bioresorbable, implant device for facilitating the healing of voids in bone, cartilage and soft tissue is disclosed. A preferred embodiment of using the implant device for facilitating the healing of a human joint lesion includes a cartilage region invested with an alginate microstructure joined with a subchondral bone region invested with a hyaluronan microstructure. The alginate selectively dispersed in the cartilage region enhances the environment for chondrocytes to grow articular cartilage. The hyaluronan selectively dispersed in the subchondral bone region enhances the environment for mesenchymal cells which migrate into that region's macrostructure and which differentiate into osteoblasts. The microstructures can be invested at varying concentrations in the regions. A hydrophobic barrier, strategically positioned within the subchondral bone region macrostructure, shields the chondrocytes from the oxygenated blood in subchondral cancellous bone.

Abstract: The present invention relates to a method and device for filtering transmission addresses in Ethernet, more particularly, to a filtering method and device provided to reduce the network loads of different groups in Ethernet. The present invention solves the problems that a large amount of memory space is required and a packet can not be filtered effectively since the the memory contents are lost when power fails in the filtering method of the prior art. The filtering method of the present invention is only to store the flag of the corresponding source address rather than the entire address data. The work for data comparing only reads out the state of the flag of the corresponding address, then refers to the differences between the state of the "0" and "1" of the flag to determine whether the packet should be blocked or allowed to is pass. The memory space will be very small due to only storing the state of the flag.

Abstract: A mechanism (10) for actuating an electric circuit is disclosed including a cover (124) having a front wall including a broad surface and movably mounted by pins (126) extending through apertures (108) formed in a mount (90, 90') of a housing (12, 12'), with the cover (124) being biased by springs (130) located on the pins (126). Tongues (136) of the cover (124) engage the legs (118) of first and second actuating arms (112, 114) to pivot the arms (112, 114) to pivot an actuation lever (100). The lever (100) includes an actuation finger (104) which pushes against the toggle (38) of a switch (36) to de-energize the circuit. Thus, when any point of the cover (124) is pushed towards the mount (90, 90'), the switch (36) is moved to de-energize the circuit. A switch lever (70) is pivotably mounted to the housing (12, 12') and is pivoted by a slideable actuator (42) to move the switch (36) to energize the electric circuit.

Abstract: An improved method or process and device for treating and healing a bone void is disclosed, and in particular a method employing a surfactant for efficiently incorporating a biologically active agent into the interstices (voids or pares) of a porous hydrophobic biodegradable material wherein the biologically active agent is deposited on the internal surfaces defining the voids or pores of the biodegradable material. The biodegradable body or device, now containing surfactant and a biologically active agent in the body itself as well as on the external surfaces and the internal surfaces defining the voids or pores, is than applied into the bone void or cavity.

Abstract: An improved adjustable armrest for use on a chair is particularly related to an adjustable armrest in connection to a pneumatically operated cylinder permitting the armrest body to be vertically lifted up by actuation of a control stick or lowered down by a manual force against the armrest body. An armrest mount having tracks defined thereon for mounting of the armrest body permits the armrest to be slidably adjusted back and forth. The armrest mount with the armrest body is secured to a housing having a vertical hole for receiving the cylinder having one end engaged with the underside of a bottom bracket which is secured to the armrest mount. The cylinder housed in a tubular sleeve is fixed at the bottom end thereof to a support bracket and is engaged with a hand operated stick at the top end so that the actuation of the control stick results in the extension of the cylinder and the armrest body accordingly.
