摘要： A load control device may be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.

摘要： A membrane digital analog switch includes an input button surface adapted to receive an input pressure from a user, and a digital switch positioned below the input button surface to generate a digital switch activation signal when the received pressure on the input button surface is greater than or equal to a specified digital pressure threshold. The membrane digital analog switch also includes an analog switch adapted to generate an analog switch activation signal when the received pressure on the input button surface is greater than or equal to a specified analog pressure threshold. The specified analog pressure threshold is greater than the specified digital pressure threshold, the digital switch activation signal is a binary digital signal, and the analog switch activation signal is variable and corresponds to an analog sensed value of the received pressure on the input button surface.

摘要： A controlling device having an activity mode corresponding to a controllable activity in which activation of a command key within a logical group of command keys of the controlling device causes a transmission of command data to control one or more functional operations of an intended target appliance. For a controllable activity the controlling device has a memory in which is stored a plurality of predetermined appliance to logical group of command keys mappings. To configure the controlling device for the controllable activity one or more predetermined keys of the controlling device are activated to thereby designate one or more intended target appliances for the controllable activity. When the controlling device is then placed into the activity mode corresponding to the controllable activity, the controlling device will use the configuration to select one of the plurality of predetermined appliance to logical group of command keys mappings to determine which appliance command data to transmit in response to an activation of a command key within a logical group of command keys.

摘要： Described herein are methods and systems for performing functions associated with a non-functional key of a keyboard present on electronic devices such as cell-phones, telephones, ATMs, etc. The electronic device is operated in a non-functional key (NFK) coding mode using NFK codes (108) that are provided to a memory component (202) of the electronic device (102). In the NFK coding mode, a user is allowed to enter functional keys in a coded sequence. Based on the NFK codes (108), the coded sequence is used to identify a function associated with a non-functional key of the keyboard and the identified function is indicated to a processor (204) of the electronic device (102) for execution.

摘要： Disclosed is a bit-state mapping method of a flash memory system which maps m-bit data (m being a natural number more than 2) onto one of 2m states (voltage threshold distributions). The bit-state mapping method includes performing a subset partitioning operation during first to (m−1)th levels under a condition that two adjacent states are processed as one state; and distinguishing between the adjacent states while processing an (m)th level.

摘要： An apparatus, system, and method that initialize a capacitive sensing switch and detects a pushed button are described. The apparatus comprises a keypad, a logic component, an initialization threshold, a measured capacitive value, and a processor. The keypad comprises at least one capacitive sensing switch. The logic component is configured to determine a capacitive sensing range for each capacitive sensing switch, wherein the range corresponds to the difference between the maximum and minimum capacitance. Each capacitive sensing switch is initialized when the capacitive sensing range exceeds the initialization threshold. The measured capacitive value measures the capacitive value for each switch and a corresponding push-button threshold determines whether the button has been pushed. The processor is configured to process computer instructions that correspond to each switch when the capacitive sensing range exceeds the initialization threshold and when the measured capacitive value for each capacitive sensing switch exceeds the push-button threshold.
