Abstract: 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.

Abstract: 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.

Abstract: In a multi-track tape player, a motor driven capstan normally drives tape past a tape head shiftable between tape tracks by a rotatable cam. An idler member is actuable to engage a driving member on the capstan to be positively rotatably driven thereby through a predetermined rotational angle and then disengage. Geneva gear apparatus connects the idler member to the rotatable cam and comprises a geneva drive member with a circular cam having a concave excluded sector and a pin and a geneva driven member having a wing for each tape track, each wing having a concave peripheral surface for normal engagement with the circular cam to hold the cam in certain rotational position and a slot between each pair of adjacent wings adapted to be engaged by the pin upon rotation of the geneva drive member to rotate the cam to its next position and thereby shift the tape head between tracks.
