摘要： A non-predictive tone-coded-squelch (TCS) frequency determination method of scanning a plurality of radio frequency channels in a radio receiver and determining the presence of a standard tone-coded squelch frequency on the radio frequency channel (205) that includes determining a mathematical average of a plurality of subaudible tone samples from a radio frequency channel (211, 217) and then removing out-lying samples that differ from the mathematical average by some predetermined amount (219). A determination is made if the number of remaining samples is at least some predetermined percentage of the total samples taken (223) and a predictive tone-coded squelch detector is used to monitor for a standard tone-coded squelch frequency nearest to the a frequency corresponding to the mathematical average of the remaining samples (225) if the number of remaining samples is at least some predetermined percentage of the total samples taken. The receiver then returns to the standard tone-coded squelch frequency if detected by the predictive detector (227, 229).

摘要： A control switch for a radio is formed using an electro-mechanical assembly (400) which includes an array of cantilevered beams (402) laminated with piezoelectric film. A movable surface (404) includes protrusions (406) positioned to deflect the cantilevered beams and generate pulsed signals in a coded manner. Electronic circuitry (410) stores the pulsed signals and associates the signals with a position of the switch.

摘要： The method of the present invention produces a plurality of bi-level waveforms on the ROW/common lines and COLUMN/segment lines of a passive multiplexed liquid crystal display (LCD). These waveforms drive the LCD display using binary data from display memory locations. At periodic intervals a counter is incremented while the counter value is then used to 1) look-up in a table the bi-level data to output on the ROW/commons; 2) look-up memory locations associated with the active COLUMN/segments; and 3) to provide inverted COLUMN/segments data before sending the bi-level data to the COLUMN/segment lines of the LCD. The counter increments from zero to four times the number of ROW/commons before being reset to zero and the waveforms repeated. Thus, an algorithm produces one ON/select voltage and one OFF/non-select voltage that are provided to the LCD.

摘要： A method of multiplex driving a passive liquid crystal display (LCD) using a bi-level LCD multiplex driver for providing one or more bi-level waveforms on the ROW/common lines and COLUMN/segment lines of a multiplexed liquid crystal display (LCD). These waveforms drive the LCD display using binary data from display memory locations. At periodic intervals the machine state is advanced with the present state used to 1) look-up in a table the bi-level data to output on the ROW/commons, and 2) look-up memory locations associated with the active COLUMN/segments; and 3) to provide inverted COLUMN/segments data before sending the bi-level data to the COLUMN/segment lines of the LCD. The states advance four times the number of ROW/commons before being reset to the initial state and the waveforms repeated. Thus, the machine produces one ON/select voltage and one OFF/non-select voltage are provided to the LCD according to predetermined formulas.
