摘要:
A new photogate pixel structure for high performance CMOS Image Sensors is proposed. A new photogate structure is incorporated into the photodiode active-pixel structure. The proposed pixel structure exhibits the dynamic integration capacitance characteristics, which can be controlled by varying the control-voltage at the photogate node. Since the sensitivity is inversely proportional to the integration capacitance, the dynamic integration capacitance characteristics can provide the new functionality and controllability for high sensitivity and high dynamic range. At a low voltage level of the photogate, the pixel sensitivity of the new photogate pixel structure is maximized due to the minimum value of the integration capacitance. At a high voltage of the photogate, the dynamic range of the new structure can be maximized due to the increased well capacity. In addition, at an optimum bias voltage of the photogate, both the dynamic-range and the sensitivity can be simultaneously improved. Consequently, the new pixel structure allows performance tunability as well as optimization in both the dynamic range and the sensitivity of the image sensor cell.

A self-magnetized motor includes a stator adapted to rotate by electromagnetic interaction with a rotator, a plurality of slot teeth formed on and surrounding a through-hole of the stator, and an excitation pole adjacent at least one slot tooth having fewer projections than remaining ones of the slot teeth. The projections are formed on ends of the slot teeth facing the through-hole of the stator. According to one non-limiting embodiment, the excitation pole may be formed between two slot teeth having fewer projections.

The steam cooking apparatus includes a cooking compartment and a steam generating unit disposed at the outside of the cooking compartment and adapted to generate steam to be supplied into the cooking compartment. The steam generating unit includes a steam generating container to receive water therein, the steam generating container having a partitioned steam generating space, and a plate-shaped heater to heat the water received in the steam generating container. The plate-shaped heater includes a plurality of heating elements having different outputs from one another, thereby having the effect of enabling rapid and proper supply of steam required to cook different foods. The steam generating container is provided with an intercepting member, which divides the steam generating container into a water level sensing chamber and a steam generating chamber. The intercepting member prevents fluctuation of water level between the steam generating chamber and the water level sensing chamber.

The plate-shaped heater includes an insulating substrate, a heating element formed of a resistor pattern-printed on the insulating substrate to generate heat, and a PTC temperature sensor to sense a heating temperature of the heating element. The PTC temperature sensor is pattern-printed on the insulating substrate, and therefore, has the effect of eliminating the risk of unintentional separation thereof, and achieving a simplified manufacturing process and reduced manufacturing costs. The PTC temperature sensor is disposed on the insulating substrate in an axis of direction having a wide distance between neighboring temperature contour lines, to achieve accurate temperature sensing capability thereof.

A reformer that directly receives heat and performs an ATR catalyst reaction and an SR catalyst reaction. The reformer includes: a reforming reactor to reform hydrogen containing fuel into reformed gas having abundant hydrogen by performing an ATR catalyst reaction and an SR catalyst reaction; a heat source contacting one side of the reforming reactor and providing the reforming reactor with heat; and an air feeder to feed the reforming reactor with air by an air flow control unit. Thus, the ATR catalyst reaction featuring a relatively short preheating time is performed while the reformer is initially operated, so that hydrogen can be produced when the reformer is initially operated, thereby efficiently operating a fuel cell.

An apparatus provides computing sources of functionality, each computing source of functionality presents a service and exists in any computing environment of the apparatus. The apparatus associates a semantic service description (SSD) with the service. The SSD has a semantic description of the service, including a semantic description of a parameter of the service, according to a computer interpretable language, and, as a service grounding, a mapping between the computer interpretable language expressing the SSD and an interface, including an interface parameter, of the service. The apparatus dynamically discovers SSDs as available services through discovery mechanisms, filters the services based upon the semantic description in each SSD associated with each service, generates a user interface to dynamically compose a task based upon selecting the services and the filtering the services to continuously present possible tasks, and generates an executable semantic service workflow description of the composed task.
