A system and method provides for the identification and monitoring of carriers within a pneumatic carrier system. Each carrier which is to be employed within the system includes an identification device such as a radio frequency identification (RFID) chip which has stored thereon identification information for the carrier. Positioned throughout the system are communications devices such as antennas and readers which are employed to read and/or write identification information on the chip. When a carrier is put in the system, a destination location can be associated with the particular carrier ID. This associated information is then employed to, among many things, monitor and confirm identity of the carrier as it moves to its destination.

A display device and a method for regulating a viewing angle of a display device are provided and can realize the automatic regulation of angle. The display device comprises: a display main body (1); a base (2); at least three voice receiving devices (3) configured to receive voice information from outside of the display device and arranged on the display main body (1) and/or on the base (2), and projections, on a horizontal plane, of the voice receiving devices (3) being not located in a same straight line; a control device configured for recording a time point when it receives the voice information inputted by each of the voice receiving devices (3), calculating time difference between time points when any two of the voice receiving devices (3) receive the voice information, determining a location where the voice information is emitted according to the time difference and sending out a rotating instruction; and a rotation device (4) configured for rotating the display main body (1) according to the rotating instruction.

A de-icing system and method for mitigating the accumulation of snow and ice on components of a communication tower includes a de-icing assembly attached to a component of a communications tower, and an air supply. The de-icing assembly includes a backing member, a pneumatic tube affixed to the backing member, and a fastener for affixing the backing to the component of the tower. The pneumatic tube is configured to be periodically inflated and deflated by the air supply to dislodge any snow or ice accumulated thereon. A controller monitors signals from a plurality of sensors to initiate the cycling of the inflation and deflation of the pneumatic tubes upon a determination that an accumulation of snow or ice is present on the component of the tower or the de-icing assembly.
