A lens assembly includes a first lens and a second lens. The first lens includes a first inner end surface, a first outer end surface and slots. The slots formed on the first inner end surface extends toward the first outer end surface, and each slot includes a trough and an inner engaging side portion. The second lens includes a second inner end surface, a second outer end surface and engaging blocks. The engaging blocks formed on the second inner end surface extends toward the first inner end surface of the first lens, and each engaging block includes a crest portion disposed next to the first inner end surface of the first lens and an inner engaging protrusion. A slit is defined by the inner engaging side portion and the trough portion of the slot and the inner engaging protrusion and the crest portion of the engaging block.

A surface mount resistor heating apparatus includes a heater including two copper foil plates electrically connected to two electric wires, and at least two surface mount resistors electrically connected between the two copper foil plates. When a low voltage electric power is applied onto the heater, the heater produces a temperature by an impedance of the at least two surface mount resistors to achieve a heating purpose. Thus, the two copper foil plates can change and diffuse a spot-type temperature distribution of each of the at least two surface mount resistors into a planar-type temperature distribution to distribute the temperature evenly and smoothly so as to instantly reduce the higher temperature produced by the at least two surface mount resistors to a determined temperature that is comfortable to a user.

A water recycling system for fuel cell includes a water trough, a first pump, a fuel tank, a mixing tank and a second pump. The water trough receives condensed water from the condenser and connects with a first throttle valve. The first pump is connected to the first throttle valve. The fuel tank is connected to a second throttle valve, and the second throttle valve is connected to the first pump. The mixing tank is connected to the first pump and the second pump respectively. A thickness sensor and a level sensor are arranged in the mixing tank to detect thickness of the fuel and liquid level of the mixing liquid in the mixing tank. The first throttle valve, the first pump, the second throttle valve, the second pump, the thickness sensor and the level sensor are electrically connected the to a micro control unit so as to actuate the first throttle valve, the first pump, the second throttle valve and the second pump under control for regulating and controlling thickness of the fuel in the fuel tank

A heating apparatus includes a carbon fiber heating layer placed in a positioning jacket which is mounted in a seat cushion, a conducting coupler electrically connected to the carbon fiber heating layer, and a control switch electrically connected to the conducting coupler. Thus, when the connector of the control switch is attached to the conducting coupler, and the plug of the control switch is inserted into the cigarette lighter of the car, the electric current from the car battery in turn flows through the control switch, the conducting coupler and the conducting cord into the carbon fiber bundles which produce an impedance to convert the electrical energy into a heat energy to heat the seat cushion to warm the user seated on the seat cushion, thereby providing a comfortable sensation to the user.
摘要:
A programmable system-on-chip (SOC) apparatus is disclosed. After connecting with a computer host, the apparatus temporarily stored boot loader codes into a volatile memory originally installed in the apparatus. Further, during the whole updating firmware procedure, no burner is required. Accordingly, the invention not only saves the hardware cost of both a non-volatile memory and the burner, but also simplifies the operation procedure.

A container system including cabinets, a main control unit connected to the cabinets and a heat dissipation zone is mentioned. The cabinet includes a plurality of serving zones each of which further includes a master server and at least one slave server. The heat dissipation zone is disposed at a side of the serving zone and coupled to the main control unit. Each slave server is coupled to the master server. The slave server includes at least one temperature sensor, and the temperature sensor is used for outputting temperature information to the master server when receiving the temperature demand. The master server collects the temperature information transmitted by each slave server. The master server forwards the temperature information to the main control unit. The main control unit drives the heat dissipation zone to dissipate heat of the serving zone according to the temperature information.

A method of reducing residual images of a liquid crystal display device includes generating multiple pulse width modulation signals corresponding to display blocks of a liquid crystal panel in turn; generating multiple driving signals corresponding to the display blocks according to the pulse width modulation signals; and correspondingly providing backlight to the display blocks according to the driving signals. During each frame period of the liquid crystal panel, each pulse width modulation signal has a first fixed width pulse voltage and a second fixed width pulse voltage. A period between a beginning of the first fixed width pulse voltage and an end of the second fixed width pulse voltage is longer than or equal to 16 milliseconds minus a predetermined time. A period between the end and a beginning of a first fixed width pulse voltage of a next frame period is shorter than or equal to the predetermined time.
