  • Patent number: 6315798
    Abstract: A metal backing for inclusion in the manufacture of a prosthetic component having a plastic bearing element on an upper surface and has a bottom surface portion with elements for attachment to a bone. The backing has an upper surface portion at least part of which is formed by a grill element having exposed front and rear faces and which is intended to be embedded within the plastic bearing member during construction. The plastic bearing material of the bearing element can be molded so that all the faces thereof exposed to the grill are covered and the grill is embedded within the plastic material of the bearing element. The grill is located on a metal support and is provided with spacers on its front face to space the front face away from the support. The grill is cast integrally into the metal support during manufacture.

  • Patent number: 6172743
    Abstract: A device for non-invasively measuring an analyte within the body uses a source of light to illuminate a tissue component, then detects and measures the light during more than one selected time period. The light source may be tuned or coupled with one or more filters to provide a selected light spectrum. The tissue component may be any extremity which contains blood and can conduct light, preferably a finger or ear lobe. The detector selects a wavelength or group of wavelengths. The light source may be varied, the source filters may be modulated, or the detector may be sampled at selected times. In general, it is desirable to take one measurement during maximum blood flow in the tissue component and a second measurement during minimum blood flow. The blood flow may be modified by pressure or temperature. The minimum blood flow measurement provides a reference to be subtracted from the signal for the analyte of interest in blood.

The grill is located on a metal support and is provided with spacers on its front face to space the front face away from the support. The grill is cast integrally into the metal support during manufacture. The casting process includes casting a grill on both outer surfaces of the metal backing with the grill element including cross-members spaced from backing surfaces.

  • Patent number: 5947257
    Abstract: An electronic coin counter for use with cash register drawers. Coins are poured from the cash register drawer through openings in the top of a housing into sleeves that correspond to the denomination of the coins. Internal sensor tips are then brought into contact with the resulting column of coins by forcing a bar outside the housing in toward the housing. This activates a switch to supply electrical power to internal electronics and to external digital displays. The sensor tips are oriented in staggered pairs to prevent counting errors due to the presence of worn thin coins. Mathematical addition and multiplication necessary to obtain the monetary value of each denomination of coin and the total value of all the coins is performed automatically by internal logic circuitry. The monetary totals are then sent to the external digital displays while the coins are automatically ejected through holes in the bottom of the housing underneath each sleeve.
