Abstract: The invention relates to methods for enabling handover for Simple IP or Mobile IP in a CDMA2000 network. In one embodiment, the new PDSN (17) establishes contact with the old PDSN (16) to obtain information about its PPP connection with the MN (11). The new PDSN (17) then sets up a tunnel between the PDSNs (16-17) and copies the PPP connection, while the old PDSN (16) dismounts its own PPP connection. The traffic now goes from the MN (11) to the new PDSN (17) that tunnels it to the old PDSN (16) that in turn forwards it through its old connection to the HA (20) or the backbone (22).        In a second embodiment, the new PDSN (17) contacts the old PDSN (16) to obtain information about the connections associated with the MN (11), and uses the information to copy the connections, while keeping contact with the old PDSN (16) to update the same information.        Also provided are systems and PDSNs (16-17) for carrying out the methods according to the inventions.        Suggested publication figure: Figure 3.

Title: Simultaneous isolation and quantitation of dna
Inventor: TEREBA ALLAN M
IPC: C12Q1/68
Filed: 2000-08-18
Abstract: The present invention provides methods for isolating a defined quantity of DNA  target material from other substances in a medium. The method may be carried out using a known quantity of a silica-containing solid support, such as silica magnetic particles, having a definable capacity for reversibly binding DNA target material, and DNA target material in excess of the binding capacity of the particles. The methods of the present invention involve forming a complex of the silica magnetic particles and the DNA target material in a mixture of the medium and particles, and separating the complex from the mixture using external magnetic force. The DNA target material may then be eluted from the complex. The quantity of DNA target material eluted may be determined based on a calibration model. The methods of the present invention permit isolation of DNA target material which is within a known quantity range. The methods of the invention eliminate the step of quantitating purified biological samples prior to further processing, such as amplification, Short Tandem Repeat (STR) analysis, and DNA sequencing. Samples of the DNA target materials may be obtained from liquid or solid media, such as liquid blood or paper.

Title: Water flow activated switch
Inventor: TRACY WYETH
IPC: H01H35/40
Filed: 2002-06-11
Abstract: A water flow activated switch is adapted to emit a water flow, and which is operated by a user obstructing the water flow therefrom. The switch includes one or more water outlets of a size which permits at least partial blockage by the user. A primary conduit tube or passage is used to fluidly connect the water outlet to a water source and defines a flow path along which, under normal flow conditions, water moves from the water source to the outlet, and outwardly therefrom as the water flow. A sensor is provided in selective fluid communication with the primary conduit. The sensor is located out of the flow path that it remains substantially inactivated during normal flow conditions, and wherein the blockage of the outlet results in a redirection of water flow to activate the sensor. The sensor is electrically coupled to a controller operable to send control signals to operate one or more electrically operated elements, such as lighting apparatus, sound apparatus, and/or electromechanical valves which regulate water flow to a water play element.

Title: Vital "and" gate apparatus and method
Inventor: EGNOT JAMES R
IPC: H03K19/007
Filed: 2000-12-29
Abstract: A method for performing an "AND" operation on two independent inputs (16, 18) in a fail-safe manner includes cascading two charge pumps (CP1, CP2) to output a condition signal representing the "AND'ed" state of the inputs. Each independent input has an active state asserted by a waveform of predetermined frequency and duty cycle, and an inactive fail-safe state asserted by a zero voltage. The method includes supplying power to a first charge pump, (CP1) supplying power from the first charge pump (CP1) to a second charge pump, (CP2) and supplying each of the independent inputs to one of the respective charge pumps. A condition signal is output using an output from the second charge pump. (CP2) Additionally, the method verifies the correctness of the frequency and duty cycle of each independent input (16, 18) using a cross connection scheme. This method provides a high-power, low-loss, and low-cost electrical circuit for operating devices responding to specific voltages, for example, vital relays.

Title: Image processing system for estimating the energy transfer of an occupant into an airbag
Inventor: FARMER MICHAEL EDWARD
IPC: G06T7/00
Filed: 2002-10-15
Abstract: The present invention relates in general to systems used to determine whether an airbag should be deployed at full or only partial strength. In particular, the present invention is an image processing system that utilizes real-time streaming video-images from a video camera or other sensor to determine the mass, velocity, and kinetic energy of the occupant at the time that the occupant comes into contact with the deploying airbag. By predicting the kinetic energy of the occupant at the time of impact, an airbag can be deployed at an appropriate strength corresponding to the kinetic energy of the occupant. The kinetic energy of the deploying back at the moment of impact should be equal to the kinetic energy of the occupant. The invention captures the volume of the occupant from an image, and uses volume to calculate the mass of the occupant. A Kalman filter is used with respect to all measurements to incorporate past predictions and measurements into the most recent estimates and predictions in order to eliminate the "noise" associated with any particular measurement. The system predicts the position and shape of the occupant at a faster rate than the rate at which the camera collects data.
