A vehicle loading ramp (10) broadly comprises a first load-bearing platform (16), a second load-bearing platform (20) preferably substantially identical to the first platform (16), and a brace (20) that can be positioned between the platforms (16,18) in order to adjust and rigidly fix a distance between the platforms. In each of several embodiments, the brace (20) may be configured to adjust the distance between the platforms (16,18) in order to accommodate different offsets between wheels of different wheeled vehicles. The brace (20) can also fix the distance between the platforms (16,18), thereby providing rigidity and preventing the platforms (16,18) from moving with respect to one another, either laterally or longitudinally.

The invention relates to an electrochemical device with safety performance. Specifically, the invention provides the electrochemical device; the electrochemical device comprises a negative electrode piece, an isolation film and a polymer layer, wherein the negative electrode piece comprises a negative electrode active material layer; the polymer layer is arranged between the negative electrode active material layer and the isolation film; the polymer layer comprises polymer particles, wherein the degree of sphericity of the polymer particles in the embodiments of the invention is about 0.70-1.0. Non-conductive or poor-conductivity non-active materials (such as, non-conductive polymer particles) are arranged between the negative electrode active material layer and the isolation film, so that the negative electrode is effectively protected, and it is ensured that failure of the electrochemical device caused by internal short circuit generation in suffering from external force impact, nail penetrating or extrusion can be prevented.

A shield that protects high-value input resistors in a power meter against unwanted effects due to electromagnetic interference from a nearby power supply and / or due to crosstalk from adjacent phases. The shield includes multiple printed circuit board shields that are arranged between each of the input resistors on a main printed circuit board in the power meter. Each PCB shield has a conductive layer that provides the shielding against unwanted energy. The resistors are arranged in a diagonal or parallel manner between each pair of PCB shields to prevent the resistor from movement, which prevents pin fatigue and fixes the value of the parasitic capacitance that is produced in the resistor-PCB-shield combination. In another configuration, the PCB shield is made of a flexible material, and snakes between and over the top or around the side ends of each resistor in a serpentine fashion, protecting the resistors from unwanted energies from both the top and the sides. The PCB shields disclosed herein eliminate variations in the percent error of the measurement phases, which contributes to achieving a highly accurate meter with an overall accuracy of less than 0.1%.

Each of contact fittings is obtained by bending a die-cut member having a metal plate portion of substantially rectangular shape and a metal piece connecting to a long side of the metal plate portion. The metal piece is folded to be accommodated within a region directly above a surface of the metal plate portion opposite a surface in contact with a front-surface electrode or a back-surface electrode. Then, the metal piece is bent along the length of the metal plate portion to form a hook to be retained by a first housing or a second housing. Therefore, as compared to a structure in which hooks are orthogonal to the length of metal plate portions and bend outward from contact fittings, the arrangement width of the contact fittings arranged in a direction substantially orthogonal to the length of the contact fittings can be reduced.

A paper staging mechanism includes a picking mechanism, a separating mechanism and a detecting mechanism. The picking mechanism picks up papers and further transmits the papers rearward. The separating mechanism separates the papers from the picking mechanism and further transmits the separated paper rearward. The detecting mechanism is mounted to rear of the picking mechanism and the separating mechanism. The separated paper by the separating mechanism co-working with the picking mechanism passes rearward through the detecting mechanism. The detecting mechanism detects a relative distance between two adjacent papers which successively pass through the detecting mechanism so as to control the picking mechanism to adjust transmission speed of the papers for achieving a fixed distance between two adjacent papers.

A pendant sprinkler head includes a sprinkler body, with an orifice that forms an inlet and an outlet. A deflector is movably supported by a deflector support assembly and is movable between a retracted position wherein the deflector is adjacent the outlet and an extended position where the deflector is spaced from the outlet. At least a portion of the deflector support assembly is located in the orifice when the deflector is in its retracted position.

A packaged transmitter device includes a base member comprising a planar part mounted with a thermoelectric cooler, a transmitter, and a coupling lens assembly, and an assembling part connected to one side of the planar part. The device further includes a circuit board bended to have a first end region and a second end region being raised to a higher level. The first end region disposed on a top surface of the planar part includes multiple electrical connection patches respectively connected to the thermoelectric and the transmitter. The second end region includes an electrical port for external connection. Additionally, the device includes a cover member disposed over the planar part. Furthermore, the device includes a cylindrical member installed to the assembling part for enclosing an isolator aligned to the coupling lens assembly along its axis and connected to a fiber to couple optical signal from the transmitter to the fiber.
