IPC: A61B5/055
Filed: 1997-04-18
Abstract: The invention provides a method for magnetic resonance imaging and spectroscopic analysis of a specimen which includes positioning the specimen within a main magnetic field and introducing an antenna having a loopless antenna portion in close proximity to the specimen.  Radio frequency pulses are provided to the region of interest to excite magnetic resonance signals, gradient magnetic pulses are applied to the region of interest with the antenna receiving magnetic resonance signals and emitting responsive output signals. A processor processes the responsive output signals to provide image information for display in a desired manner. The method in a preferred form involves employing a flexible antenna. The method in another preferred form involves employing an impedance matching circuit electrically interposed between the loopless antenna and the processor to enhance radio frequency power transfer and magnetic resonance signal-to-noise ratio from the loopless antenna to the processor. The method may be used on a wide variety of specimens and in a preferred use is introduced into small blood vessels of a patient to facilitate determination of atherosclerotic plaque.

Abstract: The invention is directed to a method of preparing a dough composition. According to the method, a batter comprising water, a leavening agent, and flour is formed. After the batter is formed, a complementary leavening agent, additional flour and other minor ingredients are added to the batter and mixed to form a dough wherein the leavening agents are distributed uniformly through the dough and the dough results in a higher specific volume upon baking. The invention is also directed to a dough composition formulated from a batter, wherein the batter comprises water, a leavening agent and flour. After the batter is formed, a complementary leavening agent, additional flour, and any minor ingredients are added to the batter and mixed to form a dough. Alternatively, the complementary leavening agent can be added in an unreactive form to the batter as long as it does not react with the other leavening agent until the dough is formed. The dough comprises from about 30 wt.% to about 60 wt.% flour; from about 20 wt.% to about 40 wt.% water; from about 0.1 wt.% to about 2.0 wt.% leavening acid; and from about 0.1 wt.% to about 2.0 wt.% leavening base.

Abstract: A system, device (214), and method for scheduling in a communication network separates each scheduling job into a committed-rate component (308) and a variable-rate component (310) according to a service class associated with the scheduling job. The committed-rate components are scheduled by creating a map of transmission opportunities that, when repeated at predetermined periodic intervals, provides each committed-rate component with its required number of transmission opportunities within its predetermined delay and jitter constraints. The variable-rate components are scheduled by assigning any unused transmission opportunities in the map to the variable-rate components according to a predetermined scheme.

Inventor: HO JOSEPH S M
IPC: H04W72/04
Filed: 1998-08-14
Abstract: A method is illustrated for reducing the call setup time of high priority calls such as voice or high speed user generated data without unduly wasting RF frequency resources on non priority calls such as short message calls. This is accomplished by ascertaining the call priority at the base station controller (BSC) level in a GSM system soon after call initiation and immediately changing the channel assignment for use by the remaining signalling type messages to a different operational speed where appropriate. The concept is further extended by supplying the call priority data to a called party's BSC such that all signalling messages after initial contact can be at the operational speed appropriate to the priority of the call.
