A structure assembled from a combination of stackable modules, each module assembled from multiple prefabricated, transportable blocks. The blocks are typically reinforced cast concrete formed in reusable molds. Module framing blocks may include arched corner blocks, key blocks that interlock with a pair of corner blocks, and optional center blocks. Other structural elements include roof, floor, and wall components that interlock with the framing modules. Modules may be stacked or nested to form structures including buildings, elevated roadways, and parking garages. Utilities may be provided through optional conduits formed in the corner elements. The framing supports raised floor modules for ease in mechanical system installation and modification. The roof elements support usable terraces and rainwater collection. The blocks are demountable and reusable. The modules are self-supporting during erection, and may be assembled without fasteners.

A fluorescent tube retrofit luminaire includes a lamp, a light guide, and a heat dissipating frame. The lamp may include a bi-pin base, middle structure, and outer structure, which may include a light-emitting diode (LED)-based light source in thermal communication with a finned heat sink section of the middle structure. Light emitted from the light source may be distributed generally along the length and / or width of the light guide. A bi-pin connector in the light guide may attach the luminaire to a first fluorescent socket. The bi-pin base may be received by a mounting aperture in the light guide before anchoring the luminaire to a second fluorescent socket using a pin-lock. The heat dissipating frame may be in thermal communication with both the light guide and the heat sink section of the lamp.

An electric terminal (1) made of sheet metal having a contact portion (3) including a top wall (7), a bottom wall (8), a first side wall (9) and a second side wall (10) and a contact spring arm (6) having: a contact beam (14) for achieving an electric contact with a complementary contact element and being integrally connected to the top wall (7) and a reinforcement beam (15), wherein the contact beam (14) and the reinforcement beam (15) together form an L-shaped cross-section, wherein the reinforcement beam (15) is only connected to the contact beam (14).

The present invention provides a torque sensor device disposed between an input shaft and an output shaft and configured to detect a torque between the input shaft and the output shaft through a relative rotation displacement therebetween. The torque sensor device includes: a housing configured to accommodate an end of the input shaft and an end of the output shaft and fixed in position to be able to perform a relative rotation with respect to the input shaft and the output shaft: a magnet unit accommodated in the housing and including a magnet ring connected to one end of one of the input shaft and the output shaft so as to be rotatably accommodated in the housing; a collector unit fixed in position to the housing in such a manner as to be disposed at the outside of the magnet unit, and configured to focus a magnetic field generated from the magnet unit; a sensing unit including a torque sensor disposed at the outer circumference of the collector unit and configured to detect the magnetic field focused by the collector unit; and a shield ring unit interposed between the collector unit and the magnet unit in such a manner as to be connected to one end of the other of the input shaft and the output shaft, and configured to change the magnetic field from the magnet unit, which is focused by the collector unit, by means of the relative rotation between the input shaft and the output shaft.
