Abstract: A method and apparatus for transmitting data from a monitoring station using frequency hopping and interval hopping as described. The output frequency of a transmitter in the monitoring station is hopped between selected output frequencies by retrieving random numbers from a table, generating a control voltage corresponding to the retrieved random number, applying the control voltage to an RF oscillator and transmitting a signal from a transmitter in the monitoring station using the signal from the RF oscillator as a carrier. The output frequency of the transmitter is limited between a maximum output frequency and a minimum output frequency by comparing the retrieved random number to data limits stored in a memory in the transmitter and rejecting retrieved random numbers outside of the retrieved limits. Interval hopping is realized by selecting a random number from the random number table, multiplying the random number by a fixed increment and adding the product to a minimum time interval.

Abstract: A flowmeter is based on the principle of injecting a pulse of microwave radiation into a flowing stream of material containing a substance having an absorption band for the radiation so as to heat a small quantity of the substance and continue its flow in a conduit to a downstream temperature sensor where the temperature of the quantity is sensed  for  enabling  determination  of the  time elapsed for the quantity to travel from the point at which  the  microwave  energy  is  injected  to  the sensor.  A microcontroller receiving  signals from the sensor determines when the peak temperature of the  quantity  is  sensed  and  uses  the  peak  to terminate measurement of a time interval.  The time interval starts when the microcontroller senses that the ac sinusoidal power has passed through zero at which  time  the  microwave  generator,  such  as  a magnetron, emits a pulse of microwave radiation for heating  the  quantity  of  the  substance  of  the material flowing in the conduit.  The microprocessor uses the known distance between where the microwave energy is injected, the cross sectional area of the conduit,  and   the duration of the time for the heated  quantity  of  the  substance  to  reach  the temperature sensor to calculate the volumetric flow of the material in the conduit.  The microcontroller transmits the results of the calculation in terms of digital numbers to various remote flow rate display devices.

Granted: 2004-03-16
Abstract: A method and apparatus determine whether reserved bits of a field are assigned a function; if not, the bits may be used for enhanced functions such as equalization and synchronization. An indication whether reserved bits have been assigned a function may be sent on a broadcast channel by a usage-information element. Decoding of the coded superframe phase/packet channel feedback (CSFP/PCF) field also is improved by reducing the number of possible codewords in the CSFP/PCF field, based on the superframe phase (SFP) information. The length of a codeword to be decoded may be reduced based on an indication in the usage-information element whether a CSFP/PCF field bit is reserved. Generally, the block code of any channel coded word, not necessarily packet data, may be effectively reduced based on knowledge of some information in the coded word.

Title: Free-flowable, directly compressible starch as binder, distinegrant and filler for compression tablets and hard gelatine capsules
Inventor: MICHAUD JACQUES LOIC MARIE
IPC: A61K47/36
Filed: 1999-02-02
Granted: 2006-05-30
Abstract: A directly compressible starch consisting in an intense white free-flowing powder showing both excellent compression profile and extremely good disintegration properties. This starch is especially designed to be used as a binder in direct compression processes where it yields very hard white tablets at relatively low compression forces. Tablets resulting from the compression of the above mentioned starch disintegrate in an aqueous medium at a very high speed and they additionally exhibit low friability pattern. This free-flowing starch also brings advantages when used as filler and binder in the filling of some hard gelatine capsules especially for these which are filled by pre-compression of the ingredients. This starch is characterised by regular and smooth partially swollen granules which can be either birefringent or non-birefringent. It can be prepared by spray-drying of a partially cooked starch.
