A DLL clock control circuit determines whether or not an operating frequency is a low frequency satisfying a prescribed condition, based on signals received from a DLL circuit and a READ control circuit. The virtual rumble strip may include a sensor that detects location data for the vehicle, and an alerting mechanism that receives the location data from the sensor. The file system defines a configuration directory storing configuration data in a binary format and migration data. Tags, links, script code and other references that may cause a different page to be accessed or loaded fro the current page are transformed or replaced on the server before the page is distributed to the attendees. Also, other embodiments including an electronic device wireless communicable with an assist device and a system including an electronic device and an assist device are also provided. Upon raising the lever through a handle portion, a distance between tips of the forked engaging arm is increased through a first plate cam, thereby increasing a distance between an upper arm and a lower arm of the forked contact member.
