摘要： A keyboard device includes M driving circuits DC(1)˜DC(M), N transition circuits TC(1)˜TC(N), a control module, M column signal lines C(1)˜C(M), N row signal lines R(1)˜R(N) and M*N key units KU(1,1)˜KU(M,N). The control module performs a scanning process to sequentially scan the M column signal lines C(1)˜C(M) in M scan cycles scan(1)˜scan(M). If the key unit KU(k,x) connected with the k-th column signal line C(k) and the x-th row signal line R(x) is depressed, a scan voltage is transmitted from the k-th column signal line C(k) to the x-th row signal line R(x) through a switch sw(k,x) of the key unit KU(k,x). The transition circuit TC(x) connected with the x-th row signal line R(x) is turned on according to the scan voltage. Consequently, an output voltage Rout(x) from the transition circuit TC(x) has a first voltage level.

摘要： A capacitive keyboard that can detect a key that has been depressed and the depressed amount thereof with high accuracy is provided. The capacitive keyboard includes a drive circuit 11 that alternatively switches the voltage of each of drive lines M from an L-level to an H-level, a sensing circuit 12 that detects the voltage generated in each of sensing lines N, and a control circuit 15 that detects, on the basis of the voltage value detected by the sensing circuit 12, the key that has been operated and the operation amount of the operated key. The sensing circuit 12 includes a peak hold circuit 32 that holds the peak value of the voltage that is input from a sensing line N over a predetermined period and an A/D conversion circuit 33 that converts the voltage held by the peak hold circuit 32 into a multi-stage digital voltage value.

摘要： A keyboard assembly includes a plurality keycaps, a plurality of sensor units and a control unit. The sensor units correspond respectively to the keycaps, and each of the sensor units is to output a pressure signal indicating magnitude of a pressure applied to a corresponding keycap. The control unit is configured to receive the pressure signal, and to determine a current repetition rate according to the pressure signal. When one keycap is depressed, the control unit repeatedly outputs a key code corresponding to the keycap at the current repetition rate while the keycap was depressed, and outputs the key code once while the keycap was not depressed.

摘要： When an array of proximity sensors is used as a keyboard, it can provide an ambiguous output if a user's finger overlaps several keys or if liquid is spilled on the keyboard. This ambiguity is reduced by an iterative method that repeatedly measures a detected signal strength associated with each key, compares all the measured signal strengths to find a maximum, determines that the key having the maximum signal strength is the unique user-selected key and then suppresses or ignores signals from all other keys as long as the signal from the selected key remains above some nominal threshold value.
