Abstract: An apparatus and method for combining multiple materials into a stream. The multiple materials may include both a major material and one or more minor materials. The minor materials are added using inlet tubes. The major and minor materials are added at transient or steady state flow rates, depending upon a command from a control signal. The apparatus and method utilize a control system which does not have flow control valves, flow control feedback loops or a dynamic mix tank. The actual flow rates track the commanded flow rates, but deviate by an error. The claimed arrangement provides a time-based error believed to be unobtainable in the prior art.

Abstract: A multi-mode transmitter (301) is adapted to modulate a data packet (200) communicated by a wireless communications signal. The data packet includes a packet header comprising a preamble (201) and a start of frame delimiter (202), and a data payload comprising a payload data length portion (203) and a payload portion (204). The packet header is modulated with a spread spectrum technique. When transmitting a data payload in one mode, the data payload is also modulated with the spread spectrum technique. When transmitting a data payload in another mode, the data payload is modulated with a non-spread spectrum technique.

Abstract: A smart-card based system and methods to control access to a plurality of attractions within a geographical area. The system may include one or more reward terminals that are located at attractions and are configured to read smart cards presented to them and, assuming the card is valid for that location, allow the card holder to access the attraction. Each smart card may be programmed with a product code that defines the attractions at which the card may be used. Product codes may be stored in a central database along with a list of the attractions associated with the each product code. The list of attractions may be updated as desired, thereby updating and changing the attractions at which any given card may be used.

Abstract: An apparatus (200) and method (300) for receiving a communications signal. A spread spectrum signal demodulator (210) is adapted to demodulate a packet header (110) of a data packet (102) that is communicated by a wireless communications signal. The packet header (110) is modulated with a spread spectrum technique and the spread spectrum signal demodulator (210) produces a packet header detection signal (220) representing a successful detection of a predefined packet header value. A non-spread spectrum signal demodulator (212) is communicatively coupled to the spread spectrum signal demodulator (210) and demodulates, in response to the packet header detection signal (220), a non-spread spectrum modulated data payload within the data packet. A data output select (234) produces demodulated data produced by either one or both the spread spectrum signal demodulator (210) and the non-spread spectrum signal demodulator (212).

Abstract: The steering angle of a vehicle is monitored using position sensors of an electric motor of an electric power assisted steering (EPAS) system. A position of the electric motor corresponding to the straight-ahead, center position of the steering system is stored in non-volatile memory during a steering calibration procedure, such as an end-of-line calibration in a vehicle assembly plant. Following power loss due to a dead battery, a steering angle zeroing procedure performed in a vehicle stability control (VSC) system generates a center position with enough accuracy to be within one electrical cycle of the motor. The pre-stored electric motor position is then used to determine the electrical cycle where the center position was located, and accurate monitoring of steering angle is resumed.

Abstract: A method and apparatus for determining a fault in an electric motor (50) determines a calculated star voltage (Vstar—calc) of the electric motor. The calculated star voltage (Vstar—calc) is compared to a measured star voltage (Vstar—meas) of the electric motor (50) to determine a star voltage error (Vstar—err). The fault in the electric motor (50) is determined when the star voltage error (Vstar—err) exceeds a predetermined maximum star voltage error (Vstar—err—max).
