Abstract:
Techniques and apparatus for securing a structure to a support are described. A mounting device may releasably secure a structure to a support. The mounting device may include a first plate, a second plate proximate the first plate, and at least one frangible connection securing the first plate to the second plate. The frangible connection(s) may be adapted to break in response to application of a shear force or other loading above a predetermined value. The mounting device may further include a retention member connecting the first plate to the second plate. The retention member may be adapted to maintain coupling of the first plate and the second plate after breakage of the frangible connection.
Abstract:
Eine Verkehrsüberwachungsanordnung (10) mit einem Gehäuse (20), das ein erstes Gehäusebauteil (21) und wenigstens ein zweites Gehäusebauteil (22) aufweist, weist ein flexibles Anschlagmittel (40) auf, durch das das erste Gehäusebauteil (21) und das zweite Gehäusebauteil (22) miteinander verbunden sind. Darüber hinaus weist die Verkehrsüberwachungsanordnung (10) wenigstens eine Sollbruchstelle (222, 29) auf, die bezüglich eines durch das zweite Gehäusebauteil (22) bereitgestellten lokalen Verbindungsbereiches (221), an welchem das flexiblen Anschlagmittel (40) befestigt ist, auf einer dem ersten Gehäusebauteil (21) abgewandten Seite der Verkehrsüberwachungsanordnung (10) lokalisiert ist.

Abstract:
A personal communication structure (PCS) may include a frame, a display housing, and a mounting system coupling the display housing to the frame. The mounting system may include four-bar linkages, each four-bar linkage including two links, first pin joints coupling first ends of the respective links to the frame, and second pin joints coupling second ends of the respective links to the housing. Rotation of the links results in displacement of the housing relative to the frame along an arcuate path. Alternatively or additionally, the PCS may include a temperature control system including a ribbed heat sink and multiple air circulation controllers. The heat sink may be coupled to the PCS frame, adjacent to a back surface of the display housing. A first air circulation controller recirculates air in a cavity within the display housing and a second air circulation controller moves ambient air across the heat sink.
Abstract:
The safety mast (1) of the invention comprises a foundation (2) and a pole (3) connected thereto via a base plate (4). The connection consists of at least one breakaway bolt (6) mounted between the foundation (2) and the base plate (4).
Abstract:
A personal communication structure (PCS) may include independently accessible compartments at least partially enclosing respective subsystems of the PCS. The independently accessible compartments may include an electronics compartment, a communications compartment, and a display compartment. The electronics, communications, and display compartments at least partially enclose a power distribution subsystem, a communications subsystem, and a display subsystem, respectively. The electronics, communications, and display compartments may be disposed, respectively, along a lower portion of the PCS, proximate a top of the PCS, and along an upper portion of the PCS. The PCS may include an access controller operable to provide access to respective interiors of the compartments. Access to the interior of a compartment may be provided to authorized users without providing access to interiors of other independently accessible compartments.
