Abstract: Automatic dispensers, proximity detectors and user-detection methods. A proximity detector can be used to trigger operation of the dispenser to dispense products such as towel, tissue, wipes, sheet-form materials, soap, shaving cream, fragrances and personal care products.

Abstract: Towel dispensing methods and automatic towel dispensers permitting conservation of the overall amount of towel dispensed. The towel dispensing methods and towel dispensers limit the amount of towel dispensed in dispense cycles which occur shortly after an initial dispense cycle. The user is provided with sufficient towel to meet the user's needs while reducing overall towel usage and limiting towel waste.

Abstract: Automatic dispensers for dispensing products such as towel, tissue, wipes, sheet-form materials, soap, shaving cream, fragrances and personal care products. A dispenser includes a housing, an electrical power source, a user input device, a dispensing mechanism, and motor control apparatus. The user input device generates a signal responsive to a user request for product. Motor control apparatus de-powers the dispensing mechanism based on a determination of dispenser conditions representing discharge of the product.

Abstract: A system includes a motor for producing motion when current is supplied to the motor and a motor controller coupled to the motor for receiving a motor current signal indicative of the current supplied to the motor. The motor controller has an analog-to-digital converter for converting the motor current signal to a sampled motor current signal. The motor controller is operable to detect pulses in the sampled motor current signal, count the detected pulses to generate a first pulse count, and determine a run parameter for the motor based on the first pulse count. A method for controlling a motor includes counting a first plurality of pulses in a motor current signal produced while the motor is activated to generate a first pulse count. A second plurality of pulses is counted in the motor current signal produced while the motor is deactivated to generate a second pulse count. A run parameter for the motor is determined based on the first and second pulse counts.
