Abstract: Methods and apparatuses for allowing mobile nodes to have access to mobility functions after being attached to their home networks. The invention allows a home agent to authenticate a registration request and validate a DHCP-acquired home address even if no mobile bindings currently exist. Typically, a home agent will not create mobility bindings if a mobile node attaches itself to a home agent network segment. By using either cached information or DHCP resources, the home agent can approve a registration request.

Abstract: Methods and apparatus for processing a registration request from a Mobile Node that has roamed to a Foreign Agent supporting Mobile IP are disclosed. In a first one of a plurality of Home Agents supporting Mobile IP, a registration request addressed to a virtual Home Agent address associated with the plurality of Home Agents is received. The registration request is then sent to a second one of the plurality of Home Agents such that the second one of the plurality of Home Agents creates a binding between the Mobile Node and the Foreign Agent. The first one of the plurality of Home Agents creates a temporary binding between the Mobile Node and the Foreign Agent. A registration reply is then received from the second one of the plurality of Home Agents. The temporary binding is then updated to create a permanent binding when the registration reply is received from the second one of the plurality of Home Agents. The registration reply is then sent to the Foreign Agent identified in the temporary binding.

Abstract: An image management system has an image database configured to store a plurality of image data files and a workstation coupled to the image database. The workstation includes a memory to store configuration data, a display, and a data processing device. The data processing device is configured to retrieve a selected image data file from the image database generate a scaling factor based on the configuration data, and generate a display signal based on the selected image data file and the scaling factor. The display is configured to receive the display signal and to generate indicia representative of the display signal.

Abstract: The invention provides for a timesaving method of determining whether a nickel cadmium (NiCd) battery is stricken with memory effect. A fully charged NiCd battery under test ("test battery") is subjected to a positive sloped current charge ramp and then a negative sloped current charge ramp while continuously monitoring the battery terminal voltage. The maximum measured terminal voltage of the test battery is compared to the measured terminal voltage of a NiCd battery of the same nominal voltage and capacity and known not to have memory effect ("normal"battery). A NiCd battery is determined to have memory effect if the maximum voltage of the test battery exceeds the maximum voltage of the normal battery.

Abstract: The invention provides for a timesaving method of determining the capacity of a nickel cadmium (NiCd). A fully charged NiCd battery under is subjected to a positive sloped current charge ramp and then a negative sloped current charge ramp while continuously monitoring the battery terminal voltage. The voltage is plotted and the maximum slope of the measured terminal voltage determines l.sub.gas. The value of I.sub.gas is compared to a temperature calibration curve to determine the capacity of the battery under test.
