This disclosure describes, in part, techniques for conserving power on an electronic device. For instance, at given time intervals, the electronic device may be sending input data to a network device and receiving audio data from the network device. The electronic device may then use one or more techniques to determine when to switch from operating in a first mode, where the electronic device sends and/or receives the data, to operating in a second mode, where the electronic device ceases sending and/or receiving the data. For example, the electronic device may make the determination based on an amount of data stored in a buffer, whether the electronic device receives data, using data received from the network device, and/or the like. Based on the determination, the electronic device may switch to the second mode in order to conserve power.

A computing device includes a base member, an input device attached to the base member and a display member connected to the base member. A sensor is attached to the base member and a controller adjusts input sensitivity of the input device when the sensor detects an object close to the display member.

It is provided it is provided a keypad comprising: a voltage bus configured to distribute power in the keypad; and a plurality of keys: a plurality of row key connections; and a plurality of column key connections: A wake-up signal causes a microcontroller to transition from a low-power state to an active state such that the microcontroller can detect which one of the plurality of keys was actuated. Each key is connected to a single row key connection and a single column key connection. Each row key connection and/or each column key connection is provided with a respective port circuit that is configured to connect the key connection with keys of the keypad when the wake-up signal is activated. Each port circuit comprises a respective port switch that is turned off in the low-power state to disconnect the column key connections/row key connections from the keys of the keypad.

Methods and apparatus for adaptive keyboard scanning are disclosed. A disclosed example apparatus to adaptively control operation of a keyboard includes at least one memory, instructions, and processor circuitry. The processor circuitry is to determine whether to operate the keyboard in a first mode or in a second mode different from the first mode, the first mode corresponding to a first number of keys, the second mode corresponding to a second number of keys less than the first number of keys, and set the keyboard to operate in the first mode or the second mode based on the determination.

A wireless keyboard, comprising a body, several keys, a first detection unit, a second detection unit and a control unit. The several keys are disposed on the body. The first detection unit is disposed on one side of the body. The second detection unit is disposed on the other side of the body corresponding to the first detection unit. The first detection unit and the second detection unit jointly detect a feedback signal therebetween. When the feedback signal corresponds to an activation signal, the control unit activates the wireless keyboard. In some implementations, the wireless keyboard can save power, and does not require users to switch on/off the power supply manually, thereby achieving the purpose of facilitating life.

A multifunctional upgradeable and expandable modular keyboard comprising a keyboard layout structure module having a plurality of keys and operatively coupled to a docking module via a docking module data and power connector and a releasable docking module fastener track and the keyboard layout structure module operatively coupled to a multifunctional modular peripheral input device via a peripheral input device fastener track and a peripheral input device data and power connector where the docking module houses a keyboard controller for communication of keystroke actuation to an information handling system and a keyboard battery. Plural sides of the releasable docking module fastener track slidingly couple the docking module and the keyboard layout structure module. Plural sides of the peripheral input device fastener track slidingly couple the multifunctional modular peripheral input device and the keyboard layout structure module. The docking module may further receive an interchangeable functional expansion module.

An electronic device, an electronic system, and an operating method thereof are provided. The electronic device includes a processor and a controller. The controller is coupled to the processor. The controller receives an input signal from an input device. The controller, based on a lookup table, performs a first control operation according to the input signal, alternatively, based on the lookup table, transfers the input signal to the processor, such that the processor performs a second control operation according to the input signal. Thereby, the electronic device is capable of increasing an efficiency of the control operation.
