At least one button is provided above the seat to control the nozzle's on/off modes when a user presses the button inwards. The button has a slot longitudinally defined therein and a locking key is movably received in the slot. The locking key has a finger extending downwards and blocked by the front housing. The button cannot be pressed when the locking key in a locked position, and can be pressed when the locking key is moved to an unlocked position to retract the finger.

摘要： A method and apparatus for masking data written to a memory device that reduces the effective write cycle time of the memory device is disclosed. Firing of the column selects is pre-empted, thereby masking data to be written to a memory device. By pre-empting the column selects, the margin required for disabling a write driver can be eliminated, thereby reducing the effective write cycle. Additionally, data masking can be performed on a per-byte basis by associating independent column selects with each data byte on multi-byte wide devices, e.g., x16 or x32.

摘要： A voltage regulator includes a power transistor receiving a drive current, and a current limit protection circuit connected to the power transistor. The current limit protection circuit includes a first resistance connected to the power transistor for sensing an output current, a limit switch transistor connected to the power transistor and to the first resistance, and a current generator and second resistance connected thereto. The current generator and second resistance biases the limit switch transistor to divert drive current from the power transistor based upon the output current through the first resistance exceeding a threshold. The first resistance has a value less than a value of the second resistance. The first resistance can be made considerably smaller than otherwise to thereby reduce power consumption. The temperature coefficient for the second resistance is balanced with respect to a temperature coefficient for the first resistance so that a output current from the voltage regulator is not sensitive to temperature variations.

摘要： An automatically adjusted magnifier for a display comprises a motor, two movable bases, two breakers, and a magnifier. The movable bases are located at either sides of the motor to connect with the motor by way of gears. Each of the movable bases has a transmission belt driven by the motor via one of the gears and a driving wheel to carry two opposite pulleys moving along a guide rail respectively. Two extensible levers in each movable base have an end thereof pivotally attached to the pulleys respectively and the other end thereof pivotally attached an engaging piece respectively so as to connect with the magnifying glass. Hence, the extensible levers may displace the magnifying glass to a best position to magnify a screen of the display.

摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.

摘要： A method and apparatus for synchronizing output data and data strobe signals uses internal interleaved clock signals in a double data rate (DDR) DRAM that are synchronized with an external clock. A delay-locked loop internal to the DDR DRAM is locked to an external clock signal and generates the internal interleaved clock signals. The internal interleaved clock signals are delay matched with the external clock signal as they propagate through timing circuitry coupled to latency and burst length selection signals. A data strobe signal is generated using clock signals from the delay-locked loop and is synchronized with the internal interleaved clock signals. The data strobe signal and the data are coupled via paths having comparable numbers and types of delay elements to provide output data and data strobe signals having predetermined delay relationships with the external clock signal.
