Granted: 2012-04-24
Abstract: An apparatus and method for causing necrosis of tissue and specifically intended for thermal ablation of the uterine cavity to cauterizing the endometrial tissue. The apparatus includes a liquid-tight, liquid filled system having a distal flexible member (14); a proximal flexible member (26);  and a catheter (16) joining and providing a liquid path between these distal and proximal members. The apparatus further includes a pressurizable pneumatic chamber into which the proximal flexible member is inserted and a means to controllably heat the contents of the pneumatic chamber. The system operates to: first withdraw substantially all of the liquid into the proximal flexible member contained within the pressurizable pneumatic chamber; second to heat this liquid to a temperature such that it can cause tissue necrosis; and third to force the heated liquid from the proximal flexible member into the distal flexible member where it is maintained for a predetermined time and at a predetermined pressure. Where this distal member has been inserted into a uterine cavity or is otherwise in contact with living tissue, the presence of the heated liquid results in tissue necrosis and cauterization.

Title: Acoustic sounding
Inventor: MARTIN ANDREW LOUIS
IPC: G01S15/34
Filed: 2001-03-08
Granted: 2012-10-02
Abstract: Methods and apparatus for atmospheric sounding using acoustic chirps are disclosed, the transmitted and echo chirps being compared in a mixer that yields frequency sums and differences. Preferably, the mixing is performed as a complex multiplication in the Fourier domain. In one system (1) a signal generator (5) such as a PC sound card drives a loudspeaker (3) that serves as a transmitter and echo pulses are detedcted by a microphone (4) that serves as a receiver. Chirps transmitted by the loudspeaker (3) travel by different paths (7a and 7b) due to reflection from TILS or thermal inversion layers (2a and 2b) at different altitudes. The transmitted and echo chirp signals are compared in a mixer (6) from which various outputs (8 and 9) can be generated.  One output (8) might be the magnitude of the difference between the transmitted and echo chirp tones, instant by instant, which is indicative of the altitudes of the respective TILs. The other output (9) might be the phase shift in an echo tone with transit time, which is indicative of vertical wind velocity at different altitudes. Such sounding methods and apparatus are useful for weather research, prediction of plume dispersal and the design of microwave links to minimize multipath fading.

Abstract: Particles incorporating a surfactant and/or a hydrophilic or hydrophobic complex of a positively or negatively charged therapeutic agent and a charged molecule of opposite charge for drug delivery to the pulmonary system, and methods for their synthesis and administration are provided. In a preferred embodiment, the particles are made of a biodegradable material and have a tap density less than 0.4 g/cm3 and a mass mean diameter between 5 µm and 30 µm, which together yield an aerodynamic diameter of the particles of between approximately one and three microns. The particles may be formed of biodegradable materials such as biodegradable polymers. For example, the particles may be formed of poly(lactic acid) or poly(glycolic acid) or copolymers thereof. Alternatively, the particles may be formed solely of a therapeutic or diagnostic agent and a surfactant. Surfactants can be incorporated on the particle surface for example by coating the particle after particle formation, or by incorporating the surfactant in the material forming the particle prior to formation of the particle. Exemplary surfactants include phosphoglycerides such as dipalmitoyl phosphatidylcholine (DPPC). The particles can be effectively aerosolized for administration to the respiratory tract to permit systemic or local delivery of a wide variety of therapeutic agents. Formation of complexes of positively or negatively charged therapeutic agents with molecules of opposite charge can allow control of the release rate of the agents into the bloodstream following administration.

Inventor: ANDERSON JAMES J
IPC: G06T17/05
Filed: 2003-02-14
Granted: 2013-08-20
Abstract: A geographical information system and a method are disclosed for geospatially mapping at least one parcel polygon within a geographical region and for displaying at least one specific attribute of each parcel polygon, i.e. a topological area within the given geographical region, as an attached attribute of latitude and longitude coordinates. The centroid or center point of each of the parcel polygons is determined and stored into conventional computer storage means. The latitude and longitude point feature at the centroid of each parcel polygon is established and similarly stored. A unique tax identification number, e.g. the Assessor Parcel Number (APN) or Parcel Identifier Number (PIN), is assigned to each of the point features. A correlation is then made between the unique tax identification number of the point feature to a text list of at least one attribute, e.g., the physical address of the parcel polygon, of each of the point features. This attribute becomes attached to each point feature. The resulting parcel polygon map and point features with one or more of the attached attributes can then be displayed within a GIS or CAD system to provide the user, for example, accurate locations of street addresses for use in environments that require pinpoint accuracy, such as emergency response.

Title: Graphical display of an animated data stream between devices on a bus
Inventor: IWAMURA RYUICHI
IPC: G06F13/38
Filed: 1997-06-20
Granted: 2006-08-15
Abstract: A graphical user interface (GUI) displays graphical images representing devices coupled to a bus structure. The bus structure is also graphically represented and illustratively coupled to each of the graphical device images. Preferably, the bus structure is an IEEE  1394 serial bus. The system is preferably a computer system. Alternatively, the system is a television, monitor or other display system coupled to and capable of communicating over the serial bus and including a control processor and a display device. When a device is added to the serial bus, a graphical image representing that device is automatically displayed in the graphical user interface. Similarly, when a device is removed from the serial bus, the graphical image representing that device is grayed out, leaving a shadow of the graphical image until the device is either re-coupled or the system is powered off. Tasks performed by the devices coupled to the serial bus are also controlled and monitored by the user through the graphical user interface of the computer system. In order to control such tasks, a cursor control device is used to choose options displayed in the graphical user interface. One or more task windows are included in the interface which help the user select the task to be performed. Once selected, controls, commands and data related to that task are displayed within a control display window of the graphical user interface. When a task requires data to be sent between devices, the flow of data between the devices over the serial bus network is graphically represented by an animated data stream within the graphical representation of the bus structure. When the data stops flowing between the devices, the animated data stream disappears. When a device is added to the serial bus, an animated stream of data temporarily flows between the graphical image of the new device and the computer system.
