Abstract: To determine whether a received signal represents a dual tone multi frequency (DTMF) code, a characteristic of the received signal is repeatedly measured over a period of time, thereby obtaining a plurality of parameter measurements. This may include separating the received signal into low band and high band signals and for each of the low band and high band signals, determining a plurality of squared magnitude measurements over the period of time. A deviation value is then determined for each of the plurality of parameter measurements, and an average deviation value is determined from the plurality of deviation values. The average deviation value is compared to a threshold value, thereby obtaining a comparison result. The received signal as alternatively designated as representing or not representing a DTMF  code on the basis of the comparison result. The step of determining a deviation value for each of the plurality of parameter measurements may include, for each of the plurality of squared magnitude measurements, determining a deviation from a predefined (e.g., unit) circle only if the squared magnitude measurement is less than the radius of the predefined circle, and setting the deviation equal to zero for all other cases. The step of determining the average deviation value from the plurality of deviation values may include determining which of the plurality of deviation values is a maximum deviation value, and determining an average deviation value from the plurality of deviation values not including the maximum deviation value.

Title: Light flashing apparatus
Inventor: PIETRINFERNO UMBERTO
IPC: H01H9/54
Filed: 1999-08-18
Granted: 2003-07-29
Abstract: The light flashing apparatus of the present invention is a four-button control switch in conjunction with an electronic circuit which is installed within an existing light switch junction box and replaces conventional switches. In addition to the two conventional on and off modes of a light switch, the apparatus allows for two different flashing modes; slow and fast flashing of the same light. The selection of any of the four modes overwrites the previous mode of operation, thereby having only one operating mode at a time. Any operating mode is selected by pushing a corresponding one of the four buttons. The slow flashing mode is used, for example, to help someone find your address when there is no hurry (taxi, delivery and so on) while the fast flashing mode corresponds to an emergency situation. The fast flash mode may also be remotely activated by a radio frequency RF signal transmitter. The apparatus of the present invention also does not require any other external source of energy to be functional, other than the existing wiring system.

Abstract: The power levels of signals transmitted by base stations in a communication are controlled. Power level control commands are transmitted from a remote station to base stations. A determination is made whether the remote station simultaneously receives a first signal from a first base station and at least one second signal from at least one second base station that include substantially identical message information.  The base stations transmit first and second reports of power levels of the first and second signals, respectively, to the controller. The controller compares the first and second reports and transmits first and second commands for adjusting the power levels of the first and second signals to the first and second base stations, respectively. Also, the step size of the adjustment of the power levels of the first and second signals by the controller is reduced during macrodiversity to reduce the signalling requirements.

Abstract: According to the invention, liquid residual oil from processing crude oil, natural bitumen or oil sand is mixed in a mixer with hot coke as a heat carrier (heat-carrier coke) whereby 60 to 90 weight per cent of the residual oil is evaporated. The proportion of residual oil which has not evaporated, i.e. the part containing metalliferous asphaltenes is converted to oil vapour, gas and coke in the mixture with the heat-carrier.  The gases and vapours are extracted from the mixer separately from the granular coke and are subsequently cooled to obtain an oil product and gas. The coke extracted from the mixer is re-heated and returned to the mixer as a heat-carrier. The liquid residual oil is mixed with heat-carrier coke in the mixer according to a weight ratio of 1:3 to 1:30, said heat-carrier coke being at a temperature of 500 to 700°C. A residual liquid film forms on the granules of heat-carrier coke as a result of this mixing process. The majority of said residual film evaporates in the mixer at a lowest possible operating temperature of 450 to 600°C. The remaining residual liquid film on the coke is converted to oil vapour, gas and coke during a retention time of 6 to 60 seconds. Dry, pourable coke is extracted from the mixer, said coke being essentially free of any liquid constituents. The gases and vapours produced are extracted from the mixer after a retention time of 0.5 to 5 seconds.
