  • Patent number: 6485486
    Abstract: The invention provides systems, methods for 14 treatment, and occlusion of the fallopian tube. An elongated catheter (22) is placed into the isthmic region (14) of the fallopian tube (16) in a trans-cervical trans-uterine fashion, and a mono-pole antenna (92) is disposed within a distal end of the catheter. The antenna radiates microwave energy in resonance to a drive frequency into tissue of the isthmic region without physical contact between the mono-pole antenna, and the tissue. This heating causes occlusion after a period of time. Typically, the catheter, and the mono-pole antenna are disposable after one treatment. In the preferred embodiment, the antenna is formed from an extension of the inner conductor of a coaxial cable coupled to a microwave generator. A power control section (24) can be used to control, and apply the appropriate microwave power to the fallopian tube tissue.

  • Patent number: 6448788
    Abstract: An improved method and apparatus for microwave imaging of an inhomogeneous target, in particular of biological tissue, compensates for the interactions between active antennae and nonactive antennae. Measured electric field data are processed in magnitude and phase form so that unwrapped phase information may be used directly in the image reconstruction. Initial finite element measurements and calculations are used to determine the perimeter dimensions of the target being examined, resulting in more accurate image reconstructions. An improved regularization technique is a hybrid of a Marquardt regularization scheme with a spatial filtering technique and a Tikhonov regularization scheme. An improved switching matrix enables simultaneous sampling of electric field data from a plurality of receiving antennae.

  • Patent number: 6427946
    Abstract: The invention includes system for modifying ice adhesion strength of ice adhered to an object. The system includes an electrode that is electrically insulated from the object and a DC source, e.g., a battery, coupled to the object and the electrode. The source generates a DC bias to an interface between the ice and the object when the ice completes the circuit. The object is conductive or is doped as a semiconductor so that the DC bias applies a voltage to the interface which modifies the ice adhesion strength selectively as compared to the ice adhesion strength with substantially zero bias voltage at the interface. The strength can be increased or decreased relative to its static state (i.e., the state without applied voltage). In this manner, ice such as ice on an aircraft wing can be removed with less work. The system preferably includes an electrically insulating material disposed between the object and the electrode; the insulating material is substantially conformal to the object and the electrode.

  • Patent number: 6408307
    Abstract: A user can access a common database from a remote communications port, at any qualified location, to generate a map or other positional information which locates selected items of interest, e.g., businesses, stores, architectural sites, and the like. The database contains information representing the items of interest, including, for each of the items of interest, positional coordinates, a geographic vicinity, and a selected category. The positional coordinates discretely locate the vicinity, while the vicinity specifies the exact locations of the items of interest in the selected category. For example, a user in New York can select the display of sporting shops in the area surrounding Chicago O'Hara International Airport selectively. A user can also access a port and display locations of items of interest within the same vicinity as the user and relative to the user's position. The database can be modified from qualified remote locations to change, or add to, the information therein.

  • Patent number: 6032299
    Abstract: A jockey jacket actuates upon sensing a particular event, such as the jockey falling from the horse during a race. A series of air tracks are inflated by a gas generator to pump up a series of air-pockets, mini-airbags, and a collar protection region, preferably with a series of concentric circular cylinders which expand and provide resistance to motions that are transverse to the concentric axis. A plurality of caps are telescopically disposed within the tracks and are forced upwards by the injected gas. These caps form a column that, together with the other columns and a support member Within the jacket collar, forms an exoskeleton around the jockey's neck. A base webbing provides support for the columns. The jacket includes microelectronics to control the jacket actuation. The jacket is usable for other activities, such as motorcycling.

  • Patent number: 5841288
    Abstract: The invention provides apparatus and methods for determining electric field properties of an inhomogeneous target. The electric property distribution on a coarse mesh discretization of the target is first estimated; and then the electric field on a fine mesh discretization of the target is computed. The fine mesh has finer discretization than the coarse mesh and is overlapping with the coarse mesh. The electric field is then measured at preselected measurement sites within a homogeneous region external to the target. A Jacobian matrix is also calculated which represents a sensitivity calculation relative to a change in the electric field at selected measurement sites due to a perturbation in the electric property distribution on the coarse mesh. A difference vector is formed between the computed electric field and the measured electric field, and an update vector is added to the electrical property distribution as a function of the difference vector and the Jacobian matrix.

  • Patent number: 5833601
    Abstract: The invention provides apparatus and methods for measuring oxygen tensions in biological systems utilizing physiologically acceptable paramagnetic material, such as India ink or carbon black, and electron paramagnetic resonance (EPR) oximetry. India ink is introduced to the biological system and exposed to a magnetic field and an electromagnetic field in the 1-2 GHz range. The EPR spectra is then measured at the biological system to determine oxygen concentration. The EPR spectra is determined by an EPR spectrometer that adjusts the resonator to a single resonator frequency to compensate for movements of the biological system, such as a human or animal. The biological system can also include other in vivo tissues, cells, and cell cultures to directly measure pO.sub.2 non-destructively.

  • Patent number: 5827425
    Abstract: A grease recovery system includes a basin with an inlet port to connect the system to a waste disposal network, e.g., a sink in a restaurant, and to an outlet port for draining substantially grease-free water into a sewer network. A grease outlet port provides for recovering grease from the system. The basin holds waste water to a level corresponding to the height of the outlet port above a floor of the basin. The inlet port is above that level so that incoming waste water drains into the basin. An inlet baffle is arranged within the basin and adjacent to the inlet port to force waste water entering the inlet port downwards toward the floor. A first blocking baffle, mounted to the floor, reduces waste water flow along the floor after the waste water passes through the inlet baffle, so that grease rises to the water level downstream of the inlet baffle. A motorized belt sub-system is mounted within the basin to rotate a belt which attracts grease to the belt's surface and along the water level.

  • Patent number: 5806980
    Abstract: A thermocouple is provided which measures the temperatures of structures at high RF potential, such as an RF electrode within a plasma CVD or plasma etch reactor. The thermocouple includes an outer conductive sheath that connects to the RF electrode at a first location, and a wire pair, connected to a second location of the RF electrode, that is used to sense the RF electrode temperature. The sheath--or a conductive member connected in circuit with the sheath--is wound into a coil to form an inductor with an impedance much greater than the impedance of the RF electrode. A large capacitor grounds the coil so that the thermocouple wires, extending through the sheath, and through and out of the coil, are available for diagnostic purposes. While RF current flows through the sheath, the wires experience the same magnetic field generated by the inductive coil, substantially grounding the thermocouple. Preferably, signal conditioning electronics remove any remaining DC bias voltages.

  • Patent number: 5798519
    Abstract: The invention monitors the driving range and tracks golf balls from users at the driving range and informs those users of characteristics such as driving distance. A solid state camera images the range, and preferably one or more tee-off positions, and collects frames of image data to track a ball's motion through space. Simulation routines augment that track and assist in isolating the start location as well as where the ball lands, or would have landed had it not been obstructed (e.g., by a net). Preferably, the invention also determines the ball's position in 3-D to increase the accuracy. In one technique, two or more solid state cameras are used, and synchronized, to specify stereoscopic imaging. In another technique, the ball's energy or physical extent is used to determine an absolute distance between the camera and the ball. A computer at the club house monitors the entire system and further manages a network including an array of displays at the several tee off positions.

  • Patent number: 5768719
    Abstract: A toilet seat includes a substantially rigid lid coupled to a pliant top. The seat seals against the rim of the standard toilet bowl and forms a pressure-adjustable cavity with the bowl and the surface of the water. Once sealed, the seat is pumped to inject air into the cavity, thereby increasing the pressure in the cavity to cause a flush operation. The lid and top each have one way pressure valves permitting air to flow into the cavity as the top is pumped. In another embodiment, the toilet has a standard toilet seat and is connected to a vacuum source via a selectively operable valve. The valve is selectively operable between an open state and a closed state, the open state creating a fluid communication path between the vacuum source and the void volume, the closed state providing a substantially airtight seal between the void volume and the vacuum source.
