An apparatus for determining the validity of a data signal communicated between two microprocessors by a dual port RAM includes a sender for providing a data signal and an initialization status indicator and a dual port RAM in communication with the sender for receiving the data signal and the initialization status indicator. The RAM has a first location for storing the data signal and a second location for storing the initialization status indicator. The sender performs initialization on the RAM at the beginning of a data transfer cycle which includes a plurality of data transfer from the sender to a receiver. The sender updates the initialization status indicator as the initialization progresses. The receiver reads the initialization status of the RAM from the second location and subsequently reads the data signal from the first location in association with the initialization status of the RAM.

A system and method ( and ) for a user of a multichannel broadcasting service listening to a particular channel provides alerts about the content currently available on other channels which are of interest to the user. Auxiliary data streams of interest can be presented for display in conjunction with the audio transmission of a related or unrelated channel. The system and method include storing criteria associated with programming or auxiliary content of interest to a user and searching for unique identifiers within the broadcast signal signifying the availability of content which meets the criteria. Content of interest can be, for example, traffic information ( and ), sports games available on other channels, sports scores, stock or other trading instruments prices, news headlines or travel information.

A antilock brake system utilizes a microprocessor controller to monitor the rate of speed decay of a braked wheel of a vehicle and to cause release of braking force under incipient wheel lock-up conditions. The microprocessor receives a single digital wheel speed input signal and processes the latter in accordance with a program whereby a reference signal is generated and is periodically compared with the wheel speed signal to determine if a lock-up condition is in progress. The microprocessor compares the speed signal with the reference signal at frequent sampling intervals and when the wheel speed decreases at a rate exceeding a desired value, the reference signal is varied by the microprocessor to decrease at a predetermined first rate of decrement until the wheel speed signal and the reference signal correspond to each other, indicating that the wheel speed is dropping at a rate in excess of a desired rate of speed decay. The microprocessor adjusts the rate of decrement of the reference signal at a second maximum rate and generates a brake release signal to relieve the brake force applied to the wheel. When the wheel speed signal again crosses over the reference signal, the brake force is restored and the reference signal again tracks the wheel speed signal at a value less than the wheel speed signal.

A method and system for transferring pulse messages between remote-controlled modules in an automotive vehicle includes a single wire bus coupled to each of the modules for transferring the pulse messages between each of the modules. A receiver circuit associated with at least one of the modules and coupled to the bus provides a communication current to the bus. A transmitter circuit associated with at least one of the modules and also coupled to the bus transmits the pulse messages utilizing the communication current. The receiver circuit, thus, becomes active and accepts the pulse messages being transmitted by the transmitter circuit upon detecting the communication current being drawn from the receiver circuit.

A wakeup generator for generating an interrupt pulse to a microcontroller (10) of an electronics module in response to a switch position change of a multi-position resistance ladder switch (14) to awaken the microcontroller (10) from a low power sleep mode. The wakeup generator uses a low current constant current source (18) and a detector(12). The low current constant current source (18) provides sense current for the switch (14) with a voltage developing across the switch varying according to the switch position selected with each switch position developing a different voltage. The detector detects a change in the voltage across the switch due to a switch position change and generates the interrupt pulse to the microcontroller.

Systems and methods are provided for increasing the geospatial resolution of traffic information by dividing known location intervals into a fixed number of sub-segments not tied to any one map providers format, efficient coding of the traffic information, and distribution of the traffic information to end-user consuming devices over one or more of a satellite based broadcast transport medium and a data communications network. Exemplary embodiments of the present invention detail a nationwide traffic service which can be encoded and distributed through a single broadcast service, such as, for example, an SDARS service, or a broadcast over a data network. Exemplary embodiments include aggregating the traffic data from segments of multiple location intervals, into predefined and predetermined flow vectors, and sending the flow vectors within a data stream to users. Confidence levels obtained from raw traffic data can both (i) be disclosed to drivers/users to supplement a very low signal (or no signal) speed and congestion report, and (ii) can also be used in various system algorithms that decide what local anomalies or aberrations to filter out as noise, or to disclose as accurate information and thus more granularly depict the roadway in question (and use additional bits to do so) as an actual highly localized traffic condition.
