  • Patent number: 7138914
    Abstract: The present invention is directed to a method of asset location. Location data is received from a cellular transmitter associated with a selected asset, which location data includes data representative of a cellular receiver with which direct communication with the cellular transmitter is made. The location data is then communicated to a tracking service system, which tracking service system includes a database representative of geographic locations associated with a plurality of cellular receivers. The database is then queried with received location data so as to generate geographic tracking data associated with a location of the cellular receiver, the geographic tracking data including display data adapted to generate a map image including a representative of a location of the selected asset.

  • Patent number: 7135967
    Abstract: The present invention is directed to a method of asset location. The method includes the step of linking at least one portable transmitter system with a selected asset. A cellular communication is then initiated from the at least one portable transmission system to an associated device controller. Primary location information representing the cellular area from which the cellular communication is made is then communicated to the device controller. A secondary location system is then initiated in accordance with the location information. The secondary location information, from the portable transmission system, is then broadcast and received into a tracking system. The method of asset location includes the steps of simultaneously monitoring a plurality of portable transmission system communications, and generating fee data representing each of a plurality of monitored portable data transmissions.

  • Patent number: 5224947
    Abstract: The subject invention is directed to a vacuum bell assembly for assisting an obstetrician in controlling and accurately attaching the cranial traction cup to a predetermined attachment point on the infant's head during childbirth. The handle is typically designed to offer a measure of flexibility when pulling traction is applied during use so that even if the obstetrician is not pulling exactly on a straight axis, the cup will not be disengaged from it's attachment to the fetal scalp thereby interrupting the delivery process. The vacuum bell assembly has a cranial extraction cup fabricated from a soft, readily expandable material. This reduces the chances of injury to the fetal scalp and to the tender tissue of the vaginal walls in the birth canal. The cranial traction cup defines an internal attachment chamber having an outer opening for attaching the cup to a portion of an infant's head located within the internal attachment chamber.

  • Patent number: 4957629
    Abstract: A filter for obstetrical fluids and particulate matter having an enclosure containing a first chamber and a second chamber is disclosed. The first chamber has a solid partition forming first and second cavities in the first chamber. The first cavity has an inlet and the second cavity has an outlet. The second chamber contains a filter and the edge of the partition is pressed against the surface of the filter.

  • Patent number: 4273281
    Abstract: The specification discloses an improved internal surgical stapler in which staples are pushed by a comb-like ram out of a magazine of a frame and are clinched by an anvil hinged to the frame and releasably latched to the frame by a latch. The latch includes a latch rod having a thumb grip and also provided with a leaf spring catch. The rod normally is in a retracted position in which its forward end is in the magazine. Then, when the user grips the thumb grip and the anvil and squeezes, the anvil is swung toward the magazine to clamp layers to be stapled and the rod is pushed out of the magazine and into a leaf spring latch in the anvil and latches. The rod is splined to the magazine until the end of this latching movement. To release the latch, the thumb grip is turned to turn the rod to move barbs on the rod out of latching holes in arms of the leaf spring catch.
