Title: Dynamic mattress support and method of operation
Inventor: JAMIESON JOHN W
IPC: A47D9/02
Filed: 1997-10-17
Abstract: An infant environmental transition system provides an infant with controlled sim ulated movements encountered by an infant in an intrauterine environment. The system includes a suspension system having a plur ality of flexures (106) coupled between a base plate (112) and a moving mattress platform (104). A cam shaft assembly (230) includes a groo ve (235) that engages a linear follower (218) connected to the moving bed platform (104) so that the follower (218) moves along the groove (235) while the cam shaft assembly (230) rotates to move the linear follower (218), and thereby reciprocate the moving mattress platform (104) in a longitudinal direction. The cam shaft assembly (235) also includes an eccentric cam (236) coupled to a rocker (242) that is cou pled to one of the flexures (106) to angularly displace the moving mattress platform (104) support on the flexures (106), and thereby provid e the composite reciprocating and rotational movements that simulate the intrauterine environment. Pulses of variable width control op erating speed of a drive motor (256), and a proximity sensor (254) associated with driver cam shaft provide operational feedback for speed re gulation and safe shutdown under adverse operating conditions. Pulse width modulation techniques generates sounds and operate visua l indicators on control panel.

Abstract: A reflex algorithm for assessing cardiac patients, which does not require human decision-making in selecting assays to be performed. Performance of further biochemical marker tests on a patient is dependent upon the outcome of previously conducted tests. The reflex algorithm focuses on obtaining the most accurate test information as early as possible from several different tests run in very short intervals. The reflex algorithm may be implemented by a computer that can copy requests for the most appropriate test to the loadlists of automated clinical chemistry and immunoassay analyzers. Also provided is an integrated platform for executing clinical chemistry assays and immunoassays according to a reflex algorithm.

Abstract: Upstream timeslots are assigned to a network terminal in a time division multiplexed communications network, by means of queue grants, each of these queue grants corresponding to a storage queue within said network terminal and associated with a particular service category. The rate of the queue grant bitstream composed of succeeding occurrences of these queue grants is thereby determined from at least one parameter of a parameter set associated to the corresponding storage queue and from at least one other parameter of at least one other parameter set associated to at least one other storage queue within any of the network terminals within the communications network. The present invention relates as well to a medium access controller adapted to perform the method, to a central station including such a medium access controller and to a network terminal including these storage queues.

Abstract: The present invention relates to a mounting structure for self-aligned flip-chip with elastic contacts. This invention solves the problem to achieve non-permanent joints combined with auto-aligning structures. It offers a symmetrical elastic alignment ensuring continued centering of the parts. This is done by using a flip-chip structure (200), which is based on a substrate (202) with an elastomer bump structure (204), moulded by using anisotropically etched silicon as a mould. The pattern of elastic bumps (204) on the substrate corresponds to pad pattern (210) on a flip-chip (214). The bumps (204) can be coated with gold, and serve both as electrical contacts (206) and for vertical positioning. Around the bumps (204) there is a guiding frame (212) of an elastomeric material with inclined frame walls (220) the same shape as the inclined walls (222) of the flip-chip (214).

Inventor: WEIRICH ANDREAS
IPC: H04J1/02
Filed: 1999-07-13
Abstract: An integrated line card for providing an analog termination for both POTS and xDSL signals that present the appropriate impedance's at xDSL frequencies for the xDSL signals and appropriate impedance's at POTS frequencies for POTS signals. The line card comprises a front end for coupling combined POTS and xDSL transceiver circuits to a telephone line at a single termination and an impedance generator responsive to the frequency range of the POTS and the xDSL circuits for generating the appropriate impedances on the line at xDSL frequencies for xDSL signals and the appropriate impedances at POTS frequencies for POTS signals, such that the signals are coupled to the card without the use of a splitter. Preferably, the xDSL circuits and the POTS circuits share a common driver for driving signals onto the loop. An advantage of this arrangement is that the two circuits may be designed together thus ensuring out-of-band noise generated by either source does not interfere with the other. In a further embodiment the generation of the frequency dependent impedance is implemented by using a feedback circuit that feeds current sensed on the loop back into the transmit driver.

Title: Method for improving steel reinforced material for tires and product produced by the method
Inventor: HETZEL PETER D
IPC: B29D30/54
Filed: 1999-08-27
Abstract: The present invention improves the fatigue resistance of steel reinforced materials such as wires or cables in a tire by treating the steel reinforced material of a cured tire either during the retreading of the tire or while the tire is in service on the vehicle. The treatment method comprises the steps of: applying a tensile force to the steel reinforced material of a magnitude equal to that of a tensile force applied on the steel reinforced material when the tire is subjected to an inflation pressure greater than approximately one hundred and ten percent (110%) of the nominal inflation pressure, and less than a tensile strength of the steel reinforced material. The treatment method also includes the step of maintaining the application of the tensile force to the steel reinforced material for a predetermined period, which alters a characteristic of the growth of cracks in the steel reinforced material.

Title: A dispensing device and method for forming material
Inventor: COFFEE RONALD ALAN
IPC: A61K47/34
Filed: 1997-07-22
Abstract: A dispensing device and method for forming at least partially solid or gel-like material from a liquid are described. In one example, at least one liquid issuing from an outlet is subjected to an electric field causing the liquid to form at least one electrically charged jet which, after formation, forms a fibre (F) or breaks up into fibre fragments (FF) or particles (D). The thus formed at least partially solid or gel-like material may be directly deposited, by virtue of the energy in the electrical field, onto a surface area, for example an area of skin enabling, for example, formation of a dressing for a wound or bum which is of high specific area and extremely absorbent. A biologically active ingredient such as for example a pharmaceutical ingredient or biological matter such as DNA may be incorporated into the fibres (F), fragments (FF) or particles (D). In another example, fibrils, particles or microcapsules incorporating a biologically active ingredient may be supplied for oral or nasal administration to an animal such as a human being.
