  • Publication number: 20080021568
    Abstract: A modular prosthetic acetabular cup for use in restorative hip replacement has an augment which can be attached to an acetabular cup outer shell to provide an acetabular cup with a cross section of a desired configuration. The augment can be attached to the acetabular cup by a coupling element having an outer dovetail portion which slidably engages a groove formed within the augment preferably open to at least a first end thereof. The inner end of the coupling element can engage screw holes of the acetabular cup. The groove of the augment further includes a second end having a gradually increasing distance from the outer surface of the shell and the inner surface of the augment on moving towards the second end of the augment.

  • Patent number: 6983643
    Abstract: For assessing ground quality, such as a condition of a racetrack, a handheld device has a shaft, a plate mounted to its bottom end, and a sensor body also mounted to the bottom of the shaft, independently of the plate. A tine tip projects below the sensor body. The sensor body has compression sensors and shear sensors. The user pushes down on the shaft. The tine tip penetrates the ground until the plate abuts the surface. Continued pushing leads to a compression reading. The user then pushes the top of the shaft so that it tilts, pivoting about an edge of the plate. Shear forces are sensed by the shear sensors. The compression and shear data pass to a data processor that computes a single value indicative of the ground quality.

  • Publication number: 20050206392
    Abstract: Various systems, methods, and programs embodied in a computer readable medium are provided for determining a worst-case impedance and worst-case voltage of a power supply loop coupled to a power input of a die. In various embodiments, the worst-case impedance of a power supply loop is determined and a reference voltage at the power input of the die associated with an average current generated at a power supply included in the power supply loop. A maximum change in a current at the power input of the die is also measured and an estimate of a worst-case voltage at the power input of the die is calculated based upon the worst-case impedance, the reference voltage, and the maximum change in the current.

  • Publication number: 20040079141
    Abstract: For assessing ground quality, such as the ‘going’ of a racetrack a handheld device has a shaft (10), a plate (16) mounted to its bottom end, and a sensor body (27) also mounted to the bottom of the shaft (10), independently of the plate (16). A tine tip (20) projects below the body. The body has compression sensors (36) and shear sensors (34). The user pushes down on the shaft (10). The tine (20) penetrates the ground until the plate (16) abuts the surface. Continued pushing leads to a compression reading. The user then pushes the top of the shaft so that it tilts, pivotting about an edge of the plate. Shear forces are sensed by the shear sensors (34). The compression and shear data pass to a data processor (26) which computes a single value indicative of ‘going’.
