Title: Method and apparatus for cordless infrared communication
Inventor: GALLO STEVEN
IPC: H04B10/118
Filed: 1997-03-19
Granted: 2003-06-03
Abstract: A method and apparatus for communicating from a base unit (40) to a plurality of portable infrared devices (48.1-48.8) are described using established communication protocols. The signals are sent along cables from the base unit via stationary infrared receiver/transmitter (RT, 46.1-46.16) modules at infrared carriers in standard transmission and receiving slots to and from the portable devices. The RT modules are distributed throughout a space in the building. Control circuits are used to assure that different infrared carrier signals, originating from nearby RT modules, arrive at any one portable device with a phase difference that does not exceed an acceptable amount. The system also includes circuitry in the base unit to select the best infrared signal detected by several RT modules from any one particular portable device. A hub is described to expand the number of RT modules with which a base unit can communicate.

Granted: 2006-07-18
Abstract: The present invention provides multi-branched wellbore systems and methods f or forming and utilizing such wellbores. An access wellbore is formed substantially in a non-producing formation. From the acce ss wellbore are drilled one or more branch wellbores into producing formations and into non-producing formations. Additional branch wellbores may be formed from the access wellbore or the branch wellbores. Seals between the access wellbore and the production wellbores ar e formed outside the hydrocarbon-bearing formations. Flow control devices and other devices are installed outside the access wellbore, thereby utilizing the access wellbore primarily for transporting fluids during production of hydrocarbons. The distance between the access wellbore and any other desired formation, such as the producing formations, is determined during drilling of the access wellbore, preferably by utilizing acoustic sensors deployed in a drilling assembly. The distance between the access wellbore and the various formations is utilized for adjusting the drilling path of the access. The branch wellbores may be utilized for storing equipment, processing and/or treating fluids, compressing gas, and redirecting gas and water downhole to improve hydrocarbon production.

Granted: 2005-10-18
Abstract: Methods for treating neoplasia, by administering reovirus to a Ras-mediated neoplasm, and use of reovirus for manufacture of a medicament for the treatment of neoplasia, are disclosed. The reovirus is administered so that it ultimately directly contacts cells of the neoplasm. Human reovirus, non-human mammalian reovirus, and/or avian reovirus can be used. If the reovirus is human reovirus, type 1 (e.g., strain Lang), type 2 (e.g., strain Jones), type 3 (e.g., strain bearing or strain Abney), as well as other serotypes or strains of reovirus can be used. Combinations of more than one type and/or strain of reovitus can be used, as can reovirus from different species of animal.      Either solid neoplasms or hematopoietic neoplasms can be treated.

Abstract: The invention relates to a method for installing anchors on the bottom of the sea. Wires (4) and a suction anchor (2) are attached to a frame (1). Through the centre of the frame's vertical axle a mounting device (6) for an anchor holder (7) is placed. The frame (1) works as a driving ramp for different shaped anchor holders and anchors (5, 15, 20). With the mounting device (6) the anchor penetrates the bottom of the sea at a certain position. A remote operated vehicle (ROV) and/or a hydraulic motor and pump gives a hydraulic torque for boring, screwing, pressing and stamping effects. A helical screw-anchor is used for rotary screwing into the bottom of the sea (3). The span and the gradient are varied given to geological data for achieving holding forces.      After use the anchor is released with a releasing mechanism (13, 14) and is left on the bottom of the sea.

Abstract: A fluid condition monitor suitable for real time monitoring of a fluid in a fluid system such as on-board vehicle monitoring of engine oil and transmission fluid to determine contamination. A capacitive spaced array electrode probe is immersed in the fluid and an oscillating voltage is applied at a first hertzian frequency and the current IB measured as an analog of the bulk fluid impedance. The voltage is also applied to the probe at a second sub-hertzian frequency and the current IS measured as an analog of the electrode surface impedance. The difference in measured currents is determined electrically compared with a predetermined threshold value; and, the measured first frequency current IB is compared with an upper and lower limit value for IB determined empirically for the known baseline fluid. If is below the threshold or IB is not within the upper and lower limits, a fault condition is declared and an indicator is activated to warn that the fluid is not suitable for continued operation of the system. An alternate embodiment includes a fluid level sensor.
