Abstract: A frequency calibration (FCAL) circuit and a method for calibrating an oscillation frequency of a controllable oscillator are provided. The FCAL circuit includes the controllable oscillator, a divider, a time-to-digital converter (TDC) and a calibration logic. The controllable oscillator generates a controllable oscillation clock according to a calibration code. The divider divides the oscillation frequency of the controllable oscillation clock by a predetermined divisor to generate a divided clock. The TDC converts a first period between first edges of a reference clock and the divided clock into a first period code and converts a second period between second edges of the reference clock and the divided clock into a second period code. The calibration logic compares the first period code and the second period code to generate a comparison result for determining whether the first period is greater or less than the second period, and accordingly controls the calibration code.

Abstract: A foldable chair can be folded easily by pressing a control member disposed at a lateral side of the seat, and when the control member is released from being pressed, the chair can be returned to the locked position by a spring. In addition to the pivot connection of the corresponding interconnected components, the structure for controlling the pivot motion and locking is also very simple, which not only reduces material cost, but also make production and assembly easier.

Abstract: A chair with waist rest and armrests comprises a connecting element, a seat assembly, a chair back, a waist rest assembly, two armrest assemblies, a height adjusting apparatus and a leg assembly.

Abstract: A folding and fixing structure of a chair backrest, both sides of one end of the backrest are disposed with a pivotal member having a pivotal portion and a locking portion, respective. The pivotal portions are pivotally disposed on two armrests. The armrests are defined at a side of their opposite surfaces with a containing portion for containing a clutch structure, respectively. Since the backrest is rotated around and is moved with respect to the pivotal portions of the pivotal members, the locking portions of the pivotal members will be slid into the containing portions of the armrests and can be restricted by or disengaged from the clutch structures. Thereby, the backrest can be folded or unfolded stably, such that the chair will occupy less space after being folded and can be assembled quickly.

Abstract: An apparatus for simultaneously folding seat back and armrest, which comprises a seat assembly, a seat back assembly, a pivoting assembly, two armrests and an adjusting assembly. The seat assembly is mounted on a base of a chair. The seat back assembly is pivoted to the seat assembly. The crank is pivoted in the seat assembly in such a manner that both ends of the crank protrude out of the seat assembly, and the protruded ends are swingable along with the rotation of the crank. The two armrests are arranged at both sides of the seat assembly and the seat back assembly; an end of each of the armrests is pivoted to the crank, and another end of the armrests is pivoted to the seat back assembly. The adjusting assembly is disposed between the seat assembly and the seat back assembly for controlling the motion of the seat back assembly and the armrests.
