Abstract: A pipette tip container includes an elongate tube that includes a sidewall that defines an interior region and an open end of the elongate tube. The elongate tube further includes an annular protrusion that extends along an inner circumference of the sidewall, wherein the annular protrusion is configured so that a pipette tip contacts the elongate tube at the annular projection and at a point along the sidewall located near the open end of the elongate tube when the elongate tube is lying on its sidewall. The pipette tip container further includes a cap secured to the open end of the elongate tube and formed to allow passage of the pipette tip.

Abstract: A high quality real-time Turbo-Mud processing system that chooses between a high complexity multi-user detectors that results in better estimates of the bit streams and computationally low linear-based-MUD/Turbo-MUD at each MUD window in each Turbo Iteration. In one embodiment this technique optimizes both the BER and the computational complexity of the receiver by using low complexity MUDs to reduce the number of symbols that the high complexity MUDs need to process. The present invention also provides an efficient means of estimating symbols transmitted in a multi-user environment in overloaded or super-saturated conditions.

Abstract: A calibration system is provided for calibrating frequency domain reflectometers in the field by using both the scattering parameters of the multi-port junction determined at the factory and changing the offset and gain terms used in generating a complex reflection coefficient by using internal calibrated loads so that heavy, cumbersome external calibrated transmission lines are not required. In one embodiment the internal calibrated loads include RLC circuits and in another embodiment the internal calibrated loads include attenuators. Further, retesting or recalibration does not necessitate reconnecting the cable under test, which may remain connected to the reflectometer's test port throughout the procedure.

Abstract: A hand-held system adapted to assist stripping of an undulating outer jacket of a twisted pair wire. The system incorporates cutters to provide two longitudinal cuts through the outer jacket of the twisted shielded pair wire. The cutters are removable and replaceable.

Abstract: An implant for use in ankle arthroplasty is provided. The implant includes a first member for cooperation with the tibia and a second member for cooperation with the talus. The second member is operably associated with the first member. The implant also includes a third member rigidly removably connectable to the second member. The third member includes a portion of the third member for attachment to the calcaneous. The third member is adapted to provide for a first position in the calcaneous when said third member is in a first relative position with respect to the second member is adapted to provide for a second position in the calcaneous when the third member is in a second relative position with respect to the second member.
