Abstract:
A programmable and input voltage independent reference voltage generator. Size of reference voltage can be adjusted by controlling size of current using current mirrors and MOS switches. No decoding circuit is necessary. By adjusting the resistance value, current mirror and dimensional ratio of MOS, a chip area smaller than a decoding circuit can be used to accommodate the reference voltage generator. The reference voltage generator is able to provide an adjustable and stable reference voltage to different types of electronic modules. By providing a highly flexible reference voltage, performance of any circuits using the generator is boosted.
Abstract:
The present invention provides a method of testing gas supply of a gas appliance, which includes the steps of: monitoring a flow rate of a gas flow through a gas regulator of a pipeline to have a detected gas flow rate; comparing the detected gas flow rate with the ideal range of gas flow rate; and providing an alarm when the detected gas flow rate exceeds the ideal range of gas flow rate. The present invention further provides a compensating method when an abnormal condition is detected. The compensating method will change the gas flow rate or the air flow rate to get a proper air fuel ratio of the mixed gas.

A separating device is put in the room, and the flame cover is connected to the burner member to cover the separating device The separating device has a main outlet and two side outlets right under the flame holes of the flame cover to generate main flames and side flames respectively.
Abstract:
The present invention provides a humidity sensor including a first conductor, a second conductor, a power supply unit, and a current sensing unit. The first and the second conductors are separated from each other for a predetermined distance and are placed at a predetermined place. The power supply unit supplies high voltage to the first conductor, and the current sensing unit senses a change of current in the conductor and generate a signal in association with the change of the current. Therefore, the humidity sensor may operate in any environment, such as high temperature and high pressure.

Abstract:
The sensor device has a casing housing a circuit board and a replaceable sensor on the circuit board. The casing has an opening corresponding to the sensor location and a manually removable cap is reliably positioned in the opening. Once the cap is removed, the sensor can be easily accessed and replaced. The cap is integrated with the casing smoothly so that the appealing of the outlook of the sensor device is minimally affected.
Abstract:
The oxygen sensing device contains a power circuit supplying the electricity required, an oxygen sensor for detecting the oxygen concentration in the atmosphere, an alarm system issuing an audible or visual alarm signal, and a controller. The controller is a computing device having a preset threshold value that continuously obtains the current oxygen concentration from the oxygen sensor. The controller then can calculate and obtain the variation rate of the oxygen concentration in a unit time. If the controller detects that the current oxygen concentration is about to drop below the threshold value, it will activate the alarm system to issue an alarm to alert people to take immediate and proper action.
