  • Patent number: 6800093
    Abstract: A spinal implant replaces excised tissue removed during spine surgery. This implant includes fasteners which firmly attach it to vertebrae adjacent to excised tissue so as to transmit tension and torsional loads to and from those vertebrae. The body of the implant has through cavities into which bone growth material is placed during surgery. The body of the implant also has a finite modulus of elasticity in compression so as to share compressive loads with emplaced bone growth material and with new bony growth facilitated by the emplaced material and the load sharing.

  • Patent number: 6782296
    Abstract: The invention relates to a method and a device, whereby a galvanometer actuator (7) that is connected to the element and a control unit are provided. Said unit generates a control signal for the actuator for adjusting the element according to a desired position time history that can be freely predetermined, whereby the control unit detects the control signal by means of the desired position time history and by considering a model (4) consisting of the unit of the actuator and the element. Said model is a time discrete state space model and is selected in such a way that said model can predict the position time history of the element for a time history of the control signal and with predetermined exactness, whereby said time history of the control signal can be freely predetermined. The predetermined desired position time history is verified by the control unit and by means of a preliminary filter and is modified with regard to the feasibility thereof if required.

  • Patent number: 6771829
    Abstract: A transform-based image compression framework called local zerotree (LZT) coding partitions the transform coefficients into small groups, each of which is encoded independently using popular zerotree algorithms. The LZT coder achieves similar coding performances as current state-of-the-art embedded coders. The advantage of this coding method is fourfold: (i) because of the reduction of memory buffering, LZT reduces the complexity of the codec implementation and increase the speed of the zerotree algorithm significantly, especially in hardware; (ii) LZT processes large images under limited memory constraint; (iii) LZT supports parallel processing mode as long as the transform in use has that capability; and (iv) LZT facilitates the coding/decoding of regions of interest. The penalty in coding performance is minute compared to global zerotree predecessors in that there are only a few extra bytes of side information.

  • Patent number: 6702774
    Abstract: A method for measurement of mass and energy transfer parameters (clearance and dialysance) in hemodialysis. A sensor is provided in the dialysate flow path downstream of the dialyzer and means are provided to add concentrate upstream of the dialyzer. A pre-determined amount of a substance whose dialysance is to be measured is added upstream of the dialyzer. The amount of substance riot dialyzed in the dialyzer is measured downstream of the dialyzer by said sensor by integrating the concentration over time. Dialysance is calculated from the amount added upstream, the amount measured downstream and the dialysate flow. In case the substance is part of the dialysate the base concentration is subtracted during integration. The addition of the concentrate upstream of the dialyzer can be done manually or, alternatively by the mixing pump of the dialysis machine. Instead of an increase of the concentration with a concentrate dilution with water can be used as well.

  • Patent number: 6701143
    Abstract: A system of advertising information on one or more mobile vehicles as a function of the vehicle's location. The system comprises mobile units and a central system for controlling the displays on the mobile units. The mobile units include displays visible from the outside of the vehicle, a controller, and a wireless communication system for repeatedly transmitting a locator signal to and receiving display-selection messages from the central system. The central system includes a wireless communication system for receiving locator signals from the mobile units, a memory and a processor. The central system determines a zone in which the mobile unit is located, selects a display to be shown by the mobile unit based on the zone that the mobile unit is located, and transmits a display-selection message to the mobile unit identifying a selected display message to be shown on the mobile unit's display.

  • Patent number: 6623443
    Abstract: Stenosis in a blood access circuit (graft, fistula) or in an extracorporeal circuit are detected by monitoring pressure pulses in the extracorporeal circuit created either by the heart or by the peristaltic blood pump of the extracorporeal circuit. By monitoring pressure pulses created by the. peristaltic blood pump loss of occlusion of the blood pump can be detected. Measurement of the pressure pulses is done either with sensors already built into the blood treatment equipment or, according to the invention, with sensors mechanically coupled to the wall of the blood tubing. The deviation of a pressure pulse amplitude proportional signal from a predetermined value indicates stenosis or loss of occlusion, respectively.

  • Patent number: 6542267
    Abstract: A passive fiber local access architecture and signaling plan is disclosed which enables the local exchange network to meet the need, as defined by the International Telecommunications Union(ITU) in References 7 and 8, for an economic means of providing a multitude of services to subscribers over a single medium. Integrating disparate signals compatibly and symmetrically over one medium dictates that all digital transmission and signaling at speeds in excess of 100 Mbps be used on the link. The additional bandwidth needed to support this expanded capacity demand points to glass fiber as the most suitable candidate for this role. A failure tolerant, diversely routed redundant ring cabling architecture provides a dedicated fiber or fiber pair to each premises from the local exchange carrier POP, eliminating the need for intermediate nodes. line power, signal splitters, amplifiers or metallic loops in the last mile.

  • Patent number: 6421464
    Abstract: This invention introduces a class of multi-band linear phase lapped biorthogonal transforms with fast, VLSI-friendly implementations via lifting steps called the LiftLT. The transform is based on a lattice structure which robustly enforces both linear phase and perfect reconstruction properties. The lattice coefficients are parameterized as a series of lifting steps, providing fast, efficient in-place computation of the transform coefficients as well as the ability to map integers to integers. Our main motivation of the new transform is its application in image and video coding. Comparing to the popular 8×8 DCT, the 8×16 LiftLT only requires 1 more multiplication, 22 more additions, and 6 more shifting operations. However, image coding examples show that the LiftLT is far superior to the DCT in both objective and subjective coding performance. Thanks to properly designed overlapping basis functions, the LiftLT can completely eliminate annoying blocking artifacts.
