Abstract: The present invention relates generally to wireless transceivers, and more particularly but not exclusively to radar detection and avoidance methodologies for wireless devices including transceivers. In one or more implementations, a method for detecting radar operating in the unlicensed 5.25-5.35 and 5.47-10.725 GHz radio bands, using wireless devices, such as WiFi AP, are provided. A WiFi AP is used to automatically detect the presence of radar on all channels in these bands, alert all of its clients, and move to another channel that is known to be devoid of radar using one or more implementations.

Abstract: A parking brake actuator for a cable-operated vehicle parking brake, comprises a mounting bracket on the vehicle, a sector gear mounted on the mounting bracket for rotation about an axis to variably tension the cable. A pedal lever is coaxially pivoted on the mounting bracket for independent rotation between a brake release position and a plurality of brake apply positions. A spiral-wound spring extends between the operating lever and the drive plate for rotating the drive plate relative to the lever to apply an initial tension on the cable. A drive clutch couples the drive plate to the lever upon initial rotation of the lever out of brake release position to enable rotation of the lever to increasingly tension the cable and apply the parking brake. The drive clutch includes a pinion gear mounted on the lever in engagement with the sector gear.
