A signal splitting device is to be installed in a CATV passive apparatus. The signal splitting device includes a circuit board that is disposed in a cover of the CATV passive apparatus, and a first connecting terminal and a second connecting terminal that are mounted to the circuit board and that are connected respectively to input and output terminals of the CATV passive apparatus. Each of the first and second connecting terminals includes a pin electrically connecting the circuit board and the corresponding one of the input and output terminals. The pin has a segment that is between the circuit board and the corresponding one of the input and output terminals and that has a length ranging from 4 to 15 mm.

An infinite rotation joint that allows members of a suspension arm assembly at the infinite rotation joint to have unlimited rotation relative to one another. The infinite rotation joint is configured to pass at least an optical signal therethrough. At least two portions of the infinite rotation joint are separable and can automatically form a unit when adjacent arms are connected together such that the infinite rotation joint can be separated into the at least two portions. The at least two portions are configured to be automatically connected to allow the optical signal to pass therethrough once the at least two portions are engaged.

Infrastructure electronics equipment incorporates infrastructure Local-Site Transports (LSTs). LSTs convey payload sampled signals over imperfect electromagnetic (EM) pathways whose physical properties are usually unknown when the equipment (e.g., Cameras, Displays, Set-Top Boxes) is manufactured. Prior LSTs hedge against EM pathway degradation in several ways: requiring high-quality cables (e.g., HDMI); restricting transmission distance, (e.g., HDMI); and/or reducing quality, via compression, to extend transmission distance somewhat (e.g., Ethernet). The subject of this disclosure is an infrastructure LST for sampled signals that causes the physical errors inevitably arising from propagation of sensory payloads over imperfect EM pathways to manifest in a perceptually benign manner, leveraging legacy infrastructure and reducing costs to achieve a favorable ratio of fidelity to transmission distance.

A system includes a downstream facing port (DFP) coupled to a video source, an upstream facing port (UFP) coupled to a video sink, and a cable. The cable includes a first end that is connected to the DFP and a second end that is connected to the UFP. The cable is configured to carry a differential auxiliary transmission signal and detect polarity in the differential auxiliary transmission signal.

A suspension arm assembly including at least two members relatively rotatable about each other at a joint, with at least one of the joints comprising an infinite rotation joint. The infinite rotation joint allows the members at the infinite rotation joint to have unlimited rotation relative to one another. The infinite rotation joint is configured to pass at least an optical signal therethrough. The infinite rotation joint includes a stator and a rotor. At least two portions of the infinite rotation joint are separable and can automatically form a unit when adjacent arms are connected together such that the infinite rotation joint can be separated into the at least two portions. The at least two portions are configured to be automatically connected to allow the optical signal to pass therethrough once the at least two portions are engaged.

An infinitely adjustable active digital television (DTV) amplifier with timing and displaying functions is connected between an antenna and a coaxial cable for detecting, adjusting, and displaying an amplification factor of the amplifier. The amplifier includes: a LNA amplifier unit having a source connected to a DC source, a RF input end connected to the antenna and a RF output end connected to the coaxial cable; an infinite adjustment unit connected to a DC potentiometer which has an output terminal connected to the source of the LNA amplifier unit for providing bias voltage; and a gain detection and a display unit having a control chip, a display driving circuit and a display screen. The control chip is connected to the infinite adjustment unit for collecting instantaneous voltage, and displaying an amplification factor corresponding to the instantaneous voltage on a display screen.
