A method includes receiving current location and heading information, receiving threshold range, and bearing values, receiving an incident report corresponding to a traffic incident at a location of interest, and selectively retaining the incident report if the point of interest is within the threshold range and bearing values.

Method and system for selectively processing traffic incident information

A control system automatically determines the presence of an auxiliary control. The system includes a controlled device and a main control. The controlled device includes a main control input and an auxiliary control input. If an auxiliary control is present, a discernible non-zero default signal is supplied on the auxiliary control input of the controlled device, when no inputs of the auxiliary control are asserted. This advantageously allows for the verification of correct assembly (i.e., determination of the presence or non-presence of an auxiliary control) without technician intervention.

Auxiliary control with diagnostic capability

A digital control device and method are provided for controlling functions such as volume and tuning for an electronic radio in response to a digital rotary switch. The apparatus includes a digital switch movable to a plurality of positions and which has a plurality of digital outputs to represent the positions. Control increments corresponding to an amount of rotation and rate of rotation of the switch are stored in a memory. The rotary switch output is periodically sampled to determine when switch movement occurs and to further determine the direction of switch rotation based on a sequence of the plurality of digital outputs. The rate of rotation of the rotary switch is then determined from counting changes in position of the switch over a sampling time A control increment is looked up in the memory that corresponds to the determined rate. The control increment is then used to change a digital output signal for controlling the electronic device. The digital output signal may control volume for an electronic radio or may include a tuner selector for selecting the tuning frequency of a radio. Accordingly, the present invention enables one to have variable control of radio functions in accordance with predetermined rates of rotation of a digital rotary switch.
