A system and method of use for attaching a safety rope to an elevated portion of a tower, e.g., an electric power transmission tower, so that the rope extends along the tower's leg from the elevated portion to a lower portion, e.g., the ground, to enable a worker may be secured to the rope by a safety device, e.g., a rope grab, to protect the worker from a fall. The system comprises an air rifle for shooting a projectile having a light weight flexible filament secured to it over the elevated portion of the tower, the safety rope, and plural rope-retaining gates. Once the projectile has been shot over the tower to carry the filament over the elevated portion the safety rope is connected to the filament and pulled over the elevated portion of the tower. The safety rope is then secured in place extending vertically between the elevated portion and the ground. Plural gates are mounted on the tower's leg at spaced locations therealong to hold the safety rope close to the tower leg so that it cannot flap or blow around in the wind. A worker can then attach a safety device on the rope and climb up the tower, while being protected from a fall therefrom.

An convertible overshoe for disposition on one primary shoe and being convertible for disposition on a larger primary shoe. Each of said primary shoes has an outer surface. The overshoe is formed as an integral unit of an elastic material, e.g., rubber, and comprises a sole and an upper. The sole includes anti-slip grit on its outer surface. The upper is in the form of a peripheral sidewall having an opening at the top edge thereof. The opening is of a sufficient size to enable a primary shoe to be extended therethrough so that it is received closely within the overshoe to prevent the overshoe from falling off. The sidewall of the upper includes a reinforcing strip in the form of a continuous thickened bead extending along a portion of the peripheral edge of the opening and spaced below that edge and an associated contiguous portion defining a trim line. The material of the sidewall at the trim line is readily severable so that it can be severed to remove the sidewall portion of the upper from it to the opening. This action forms an enlarged opening in the upper for a larger primary shoe to be extended through it into to overshoe. The reinforcing bead prevents the overshoe from tearing at the enlarged opening should that opening be stretched when the larger primary shoe is inserted therethrough.

Apparatus and methods for changing one or more functional or operational aspects of a wireless device, such as upon the occurrence of a certain event. In one embodiment, the event comprises detecting that the wireless device is within range of one or more other devices. In another variant, the event comprises the wireless device associating with a certain access point. In this manner, various aspects of device functionality may be enabled or restricted (device “policies”). This policy enforcement capability is useful for a variety of reasons, including for example to disable noise and/or light emanating from wireless devices (such as at a movie theater), for preventing wireless devices from communicating with other wireless devices (such as in academic settings), and for forcing certain electronic devices to enter “sleep mode” when entering a sensitive area.

摘要:
An access point that implements operating modes in which beacons may be selectively disabled. Beacons may be disabled when no device is actively associated through the access point. Beacons may be enabled in response to one or more triggers, which may include events such as a client forming an association through the access point following a probe request message identifying the access point. In addition, active beaconing may be triggered by user input or may occur during periodic brief intervals that allow client devices to discover the network identifier for the access point. Selective control of beaconing may lead to more effective wireless communication, particularly in areas where users congregate with computers implementing soft APs for personal networks.
