Title: Feedback technique for wireless systems with multiple transmit and receive antennas
Inventor: CHUNG SEONG-TAEK
IPC: H04B1/04
Filed: 2001-11-09
Abstract: In a wireless communication system using multiple antennas at the transmitter and multiple antennas at the receiver, a so called multiple-input multiple-output (MIMO) system, a substantial improvement in capacity over the case of no feedback can be achieved using considerably less bandwidth than is required to feedback the channel estimate or channel statistics, by supplying as feedback for each data substream of an overall data stream an indicator of a rate and/or an indicator of a gain for transmission of that data substream. The indicator of the rate and/or the indicator of the gain may be the rate and/or gain directly or an encoded representation of the rate and/or gain. Typically, the best performance is achieved if indicators of both the rate and the gain are fed back. If the invention is implemented for wireless systems, then typically for each data substream there is a separate, independent antenna. The rate and the gain are computed as a function of a channel estimate which is developed at the receiver. Advantageously, the transmitter may employ only one-dimensional data coding for each of the data substreams.

The adhesive systems include an epoxy resin or other compoun ds such as terminal olefins which are known to react with thiols (polymerizable  material). Preferably, the compounds are used in combination with amine curatives as a two-component curing system for epoxy resins. Such a composition provides a two-stage cure which enables very quick achievement o f bonded parts with handleable strength at room temperature or below, or with relatively low bake temperatures. The materials can be used for coatings, adhesives, sealants, potting compounds, and the like.

Title: Coriolis flowmeter with reduced dimensions
Inventor: CRISFIELD MATTHEW T
IPC: G01F1/84
Filed: 2000-03-15
Abstract: A Coriolis flowmeter sensor (10) having a reduced flag dimension. Flag dimension is the length that a flow tube loop extends outward from a pipeline. In order to have a reduced flag dimension, the entire length of the flow tubes (103A-103B) must vibrate to make the flowmeter sensor (10) more sensitive to Coriolis effects. When the entire length of the flow tubes vibrates, a first set of brace bars (122-123) connected to the flow tube separates the frequencies of vibration in the flow tubes (103A-103B). A second set of brace bars (120-121) connected to the flow tubes enhances the zero stability of the flowmeter.

Title: Potable water circulation system
Inventor: POIRIER BLAIR J
IPC: E03B7/02
Filed: 2002-03-18
Abstract: The present invention relates to systems for circulating water in a potable water piping network to prevent the stagnation of water in this piping network. Several systems are disclosed wherein partitioned pipes, pumps, partitioned headers, check valves, and scoop inserts are used to keep the water in movement inside the pipes. The present invention comprises several pumping arrangements for circulating water inside fire hydrant laterals and inside the branch pipes along dead-end streets where most of the water stagnation occurs. Although partitioned pipes are used and opposite flows are induced in opposite pipe halves, full pipe flow to each hydrant is maintainable in case of emergency. Inside buildings, the water is kept in movement inside a loop pipe that extends close to each water outlet such that the water is maintained fresh at each outlet.

Title: Electro field sensor
Inventor: BRUN DEL RE RICCARDO
IPC: A61B5/0408
Filed: 2000-08-25
Abstract: An electric field sensor employs a capacitive pick-up electrode in a voltage  divider network connected to a body emanating an electric field. The system is relatively insensitive to variations in the separation gap between electrode  and body, reducing sensor motion artifacts in the output signal and stabilizing its low frequency response. The pick-up electrode may be positioned at a "stand off" location, spaced from intimate contact with the surface of the body. This is equivalent to providing low level capacitive values for the capacitive coupling between the pick-up electrode and the bod y whose electric field is to be monitored. Or a series limiting capacitor may be provided in the input stage. Human body-generated electrical signals may be acquired without use of conductive gels and suction-based electrodes, withou t direct electrical contact to the body, and even through thin layers of clothing.

Abstract: A control system (11) controls the motion of a physical subject (36) such as  a mechanical system via a single transducer (10) which alternates in a time- discrete manner between the task of reading a signal indicative of the state  of the subject and the task of influencing said state by the application of a force. Control of motion or vibration is achieved through a series of actuating pulses interleaved with sensing operations. The same single transducer (10) alternately acts as input to the control system (11) from th e subject and output from the control system (11) to the subject. The control system (11) provides full and individual control of all important harmonic modes of vibration of a subject mechanical system.

Abstract: The present invention discloses a method of calculating a static formation temperature in a reservoir penetrated by a wellbore. One embodiment of the present invention comprises estimating the static formation temperature and calculating a formation fluid temperature at the wellbore, the calculation based, in part, on the estimated static formation temperature. The temperature of a sample of formation fluid at the wellbore is measured. The calculated formation fluid temperature at the wellbore is compared with the measured temperature of the sample of formation fluid. The static formation temperature is predicted by altering the estimate of the static formation temperature until an error between the calculated formation fluid temperature at the wellbore and the measured fluid formation temperature is minimized.
