Abstract: A rotary sprinkling head structure of a sprinkling gun including a gun body, an anti-detachment ring, an inner cap, and a rotary cap. The front end of the sprinkling head of the gun body is disposed with a variable water discharging head and an outer stop slope is adjacent to a rear side of the variable water discharging head. Several water exits are formed behind the outer stop slope and a slope guide face is formed behind the water exits. An anti-detachment ring groove is formed behind the slope guide face. An adjusting outer thread is formed at the rear end of the sprinkling head and several annular engaging ribs are formed on the outer circumference of the rear section of the inner cap.

Abstract: Improved calibration of optical wavelength measuring instruments. In a first embodiment, improved calibration is achieved in an optical wavelength measuring instrument by performing calibration measurements at a plurality of known wavelengths and using an average calibration constant derived from the plurality of measurements. In a second embodiment, improved calibration is achieved by performing calibration measurements at a plurality of known wavelengths and calculating a linear or higher order calibration model, or a periodic model. These approaches may be extended by segmenting the wavelength range and using different calculated calibration values, or different calibration models, for each segment.

Abstract: Wavelength reference standard using multiple gasses and calibration methods using same. A wavelength reference using absorption lines of multiple gasses provides stable reference wavelengths over multiple regions of interest of the optical spectrum. The gasses may be in separate cells or combined in one cell. Improved calibration using the reference is achieved by performing calibration measurements at a plurality of known wavelengths and using an average calibration constant derived from the plurality of measurements. In a second embodiment, improved calibration is achieved by performing calibration measurements at a plurality of known wavelengths and calculating a higher order calibration model, such as a least-squares linear fit. Both approached may be extended by segmenting the wavelength range and using calculated calibration values for each segment.

Abstract: Disclosed is a system for saving electrical power (II) comprising an external device, a control unit and a sensing device which is a directive switch and can sense the variation of angle. One end of the sensing device is connected to ground, another end of the sensing device is connected to the input of the control unit. The microcontroller will be switched to a power down mode from normal operation if the external device is not being accessed for a specific duration. Therefore, the PSEN pin of the microcontroller will be switched from a logical high state to a logical low state. At this time, the microcontroller will be triggered to recover the normal operation of external device if the sensing device senses angle change, thus reducing electrical power and prolonging the battery life.

Abstract: A drip type watering device for gardening use is disclosed; and more particularly it relates to a watering device which is inserted partially into soil to permit water, liquid fertilizer or chemicals for change of nature of soil of plants to be discharged drop by drop automatically without periodically watering by manual labor. It is made up of a container, an adjustment cap, a sealing lid and an insertion means. The adjustment cap adjustably engaged with the sealing lid is removably secured to the container is used either to precisely regulate the volume of water to be discharged with ease or to effectively seal a container associated with the watering device to prevent water from leaking out.

Abstract: An adaptor module allows an electrical connection to be established between a communication system and a communication card. Advantageously, the adaptor module can be configured to provide an interface between the communication card and various communication systems such as conventional telephone systems, cellular telephone systems, digital telephone systems, local area networks (LANs), personal area networks (PANs) and wireless systems. In addition, the adaptor module can provide an interface between a plurality of communication systems and the communication card. For example, the adaptor module may provide an interface for a plurality of connectors from the same type of communication system and/or the adaptor module may provide an interface for connector, from different types of communication systems. Advantageously, the adaptor module can provide simultaneous communication with these various communication systems.

Abstract: A telephone line state detecting device that is connectedly provided with a hardware detecting circuit when a telephone line is connected to a modem. The hardware detecting circuit is connected to a processing unit such that, in use, the hardware detecting circuit can detect pulses generated by voltages flowing through the telephone line. The pulses are being processed by the processing unit to judge whether the telephone is disconnected or the electrical contact thereof is deficient, or whether the telecommunications equipment used in conjunction therewith is busy or not in use.

Abstract: A rotary dimmer switch mounting structure for a floor lamp, comprising two tubes connected by a pipe connector and fastened in a floor to support a lamp, and a rotary dimmer switch received inside the pipe connector and the tubes and controlled by a revolving shaft to regulate the intensity of light produced by the lamp, wherein the pipe connector has an elongated slot longitudinally extending from either end edge thereof for receiving the rotatable control shaft and therefore, the diameter of the tubes can be smaller than the total height of the shaft.
