Abstract: An integrated circuit includes an oscillator circuit, where a frequency of an oscillator output signal provided by the oscillator circuit is adjustable by either coupling a resistor to an input pin, or by applying an external clock signal to the input pin. The oscillator circuit includes a comparator, a follower, a current-controlled oscillator, and a switch circuit. The switch circuit is coupled between the input pin and a node that is coupled to the current-controlled oscillator. Also, the follower is arranged to cause the voltage at the node to be at a pre-defined voltage unless the voltage at the node is overdriven by an external clock signal. The comparator circuit is arranged to determine whether the signal at the input pin is a clock signal. If it is determined that the signal at the input pin is a clock signal, the switch circuit is opened.

Abstract: The present invention includes a smoking cabinet and a central air supply system. The central air supply system includes an air-draining pipe and an air supply pipe connected with the smoking cabinet. The other end of the air supply pipe is connected with an air supply unit to supply cooking smoke to the smoking cabinet. The air supply pipe is connected with a compression motor. The other end of the air-draining pipe is connected with an air-draining pump to drain cooking smoke from within the smoking cabinet, and the air-draining pump is connected with an air-recycling unit. Thus, the compression motor and the air-draining pump respectively supply and drain compressed cooking smoke repeatedly so the meat inside the smoking cabinet swells and shrinks repeatedly. The cooking smoke can penetrate the meat quickly so that it the time required to cook the meat is drastically reduced and keeps the meat fresh.

Abstract: Products and methods for treating fibrosis, liver cirrhosis and cancer, and for altering or modulating the expression of genes regulated by transforming growth factor—beta (TGF-?) are provided. Nucleic acid molecules comprising TGF-response elements have a high affinity for transcription factors modulated by TGF-?. In one embodiment, nucleic acid molecules comprising TGF-? response elements can be used as decoys to alter the expression of genes regulated by TGF-?

Abstract: A controller for a synchronous switching regulator is arranged to control a switch with a control signal, and to control a synchronous switch with a synchronous switch control signal. The controller disables the synchronous switch control signal at power-up so that the regulator operates with asynchronous rectification. Also, the controller is arranged to detect whether the regulator is in discontinuous or continuous conduction mode by determining whether a switch node voltage at the switch node a switch node stays negative. The regulator keeps operating with asynchronous rectification until the switch node voltage stays negative for the entire off period of the switch, which indicates the regulator is operating in continuous conduction mode. At this point, the controller enables assertion of the synchronous switch control signal, so that the regulator operates with synchronous rectification. The controller is arranged to enable the output voltage to rise monotonically when driving a prebiased load.

After the first PWM pulse or at the end of a soft-start, a gradual transition is made from asynchronous rectification to fully synchronous rectification. The gradual transition to synchronous rectification is made by gradually increasing the time that the synchronous switch is enabled to be on.

Abstract: A lighting device has a body for holding a battery cell and a connected head that has a lens having several light deflecting portions. A number of light sources, such as super LEDs, are mounted within the head for energization by the battery cell to emit light through the lens, with light from the individual light sources being merged together by the light deflecting portions. A switch on the body switches on and off the light sources. The light sources comprise two groups of different colours. The head is rotatable relative to the light sources for aligning the light deflecting lens portions with the light sources of either one group selectively for merging the light of the corresponding colour from that group.

Abstract: A method and apparatus is directed to generating an improved temperature coefficient for the current limit in a switching regulator/driver circuit. The current limit sense circuit includes a comparator that compares two signals to determine when the current limit has been exceeded. One signal is produced from a temperature independent voltage source, a trans-conductance cell, and a sensor resistor circuit. Another signal is produced by an active output circuit, such that the signal corresponds to the current associated with the switching regulator/driver circuit. The current sensed by the regulator/driver is temperature dependent due to the resistances in the active output circuit, the sensor resistor circuit, and the trans-conductance cell. Each of these resistances has a temperature coefficient. The temperature coefficients determine the amount of temperature dependence in the sensed switching/regulator current.

This device involves a servomotor and a inverter, for respective control of the revolutions of front, middle, and rear rollers of the ring spinning machine and the spindle, so the drafting rate and twisting of all areas of the ring spinning machine can change continuously with pre-defined settings, to produce yarns with variable number of counts and twisted conditions. The design of variable waveforms can also achieve different touch and visual feelings.
