Pulse width | 3 |
| 20130027192 | MOTOR CONTROL METHOD - A motor control method comprises: inputting a PWM signal into a control unit for the control unit to obtain a direction command and a speed command by an identification rule, and generating a control signal according to the direction and speed commands by the control unit; and generating a driving signal according to the control signal by the driving unit for driving a motor to operate according to the direction and speed commands. | 01-31-2013 |
| 20130229268 | TRANSMISSION OF POWER AND DATA AT MULTIPLE POWER LEVELS - In one embodiment, an apparatus includes a circuit coupled to a line, where the circuit may power a device, and where the power is transmitted to the device over the line as a pulse-width modulated signal. The circuit may set a duty cycle of the pulse-width modulated signal in order to transmit a determined power level to the device. The apparatus may vary a frequency of the pulse-width modulated signal to transmit data to the device while the duty cycle of the pulse-width modulated signal is fixed in order to continue to transmit the determined power level to the device. A variation in the frequency of the pulse-width modulated signal may be detectable by the device and represents at least a portion of the data. | 09-05-2013 |
| 20140139325 | PROCESS AND DEVICE FOR THE TRANSFER OF SIGNALS - A process for transfer of signals is provided between a first control unit and at least a second control unit, wherein the first control unit, based on the input data, selects at least a first signal that is to be transferred, and the first control unit has at least one signal output, at which a first PWM signal can be emitted, wherein a first PWM signal is encoded and assigned to each selected at least one first signal, and wherein the second control device has one first signal input, which receives the first PWM signal and the second control device evaluates the first PWM signal received and detects the first signal and, based on the first signal transferred, creates a subsequent control instruction. A related device is also disclosed. | 05-22-2014 |

Pulse spacing (e.g., pulse repetition rate, etc.) | 2 |
| 20120256735 | REMOTE CONTROL INTERFERENCE AVOIDANCE - Computer readable media, methods and apparatuses may be configured for determining a rate of signal pulses transmitted by a device and a transmission interval occurring between a first of the signal pulses and a second of the signal pulses, detecting selection of a command by a user, and transmitting at least a portion of the command during the transmission interval. | 10-11-2012 |
| 20130176117 | ELECTRONIC APPARATUS AND METHOD FOR DETECTING INFORMATION USING THE SAME - An electronic apparatus is provided. The electronic apparatus performs two-way communication with a remote control device, and includes a receiving unit which receives a data signal from the remote control device, a signal processing unit which performs signal processing to convert the received data signal into a pulse signal and a control unit which detects information included in the data signal based on a time interval between starting points of pulse periods which are in a row in the pulse signal. | 07-11-2013 |
