A brush is secured at a first end thereof to the lower substrate and contacts at a second end thereof to the commutator to form a contact part.
Abstract:
A fluid-pressure regulator for regulating the pressure of a fluid. The regulator includes a variable-resistance fluid element and a variable-volume fluid element located downstream of the variable-resistance element. Pressure in the fluid at the outlet of the regulator is controlled by substantially simultaneously changing the resistance of the variable-resistance element and the volume of the variable-volume element. In one example, a decrease in pressure is effected at the outlet by simultaneously increasing the resistance of the variable-resistance element and increasing the volume of the variable-volume element. Some embodiments of the regulator are particularly useful to effect long-term and high-speed pressure changes in high-resistance fluidic channel networks.
Abstract:
A gigabit passive optical network (GPON) system for fiber to the home (FTTH) service must provide a down-stream data rate of an optical band to provide IPTV service with hundreds of channels to subscribers, and must be able to provide an upstream data rate of an optical band using a currently available BM-IC chip. A currently available BM-IC chip for a GPON has 1.244 Gbps and 2.488 Gbps modes. Accordingly, an optical network terminal (ONT) for a GPON that is capable of providing a downstream transmission band of 10-Gbps and an upstream transmission band of 1.244 Gbps or 2.488 Gbps, and a method for processing an upstream frame in the terminal, are provided. The GPON ONT can provide 20 Mbps, high-definition IPTV service with 500 channels and can provide both upstream data rates of 1.244 Gbps and 2.488 Gbps according to a user's selection without using an additional device.
Abstract:
A home appliance and home appliance system are provided which enable a portable terminal not to recognize an acoustic signal sound corresponding to product information output by the home appliance as noise. Thus, the acoustic signal corresponding to product information output by the home appliance may be transmitted to a service center through the portable terminal. The home appliance may include a controller that sets a dead time at a predetermined interval of time with respect to a signal corresponding to product information to avoid a noise detection section of a portable terminal, a converter that converts the signal into an acoustic signal of a predetermined band, and a sound output device that outputs the acoustic signal as sound.
