Particular embodiments described herein provide for a privacy cover in an electronic device. The electronic device includes a camera facing a first direction towards a user, an illumination source facing a second direction, opposite the first direction, and the privacy slider. The privacy slider includes a camera cover, an illumination source reflector, and an indicator that is illuminated by the illumination source when the camera is covered by the camera cover, where the indicator is located in a plane that is perpendicular to a plane that includes the camera.

A mobile device allows transmission of additional outgoing application data requests in response to occurrence of receipt of data transfer from a remote entity, user input in response to a prompt displayed to the user, and a change in a background status of an application executing on the mobile device. Additional outgoing application data requests are foreground application requests.

A system for computing devices includes a central processing unit (CPU that is configured to perform in a plurality of power modes, each power mode being pre-defined to have a different code-execution performance capability than remaining ones of the plurality of power modes. The system further includes a sampling peripheral, an electrical output, and a memory device. The memory device is configured to select and execute a specific module from the plurality of modules based on the context-identifying input triggering the specific module. If triggered, each module is executed to receive the context-identifying input from the sampling peripheral, and to operate the CPU in a dedicated power mode of the plurality of power modes.

The present embodiment relates to a touch power management circuit and a touch driving system including the same, and more particularly, to a touch power management circuit that prevents unnecessary power consumption during a pen touch driving period in order to reduce power consumption of a display device, and a touch driving system including the same.

A method for generating mark information in a virtual environment includes displaying a target-perspective picture showing the virtual environment, a sight bead pointing to an aiming position, and receiving a mark operation triggered on a mark control interface. The method further includes, in response to receiving the mark operation, generating, according to the received mark operation, mark information on a virtual object to which the aiming position points. The virtual object on which the mark information is generated is a movable object, a virtual prop, a virtual building, or a virtual landscape object in the virtual environment. The generated mark information is visible at a position of the virtual object in the virtual environment to one or more teammates of the virtual character.

Passive Ethernet by-pass switches, methods of using the same, and systems including the passive Ethernet by-pass switches include a first connection configured to be coupled to a first Ethernet port, a second connection configured to be coupled to a second Ethernet port, and switching circuitry including at least one internal switch operable to allow network communication between the first connection, the second connection, and at least one Ethernet controller, the at least one internal switch including a depletion mode transistor operable to bridge the first connection to the second connection to establish communication between the first connection and the second connection.

A wearable device and a system that includes the wearable device is provided. The wearable device includes at least one sensor configured to sense a characteristic of a user, a communication interface configured to obtain a first identifier of a vehicle or equipment, and a controller. The controller is configured to monitor the user based on the first identifier or send the first identifier to a monitoring system; determine whether there is a harm possibly occurring to the user of the wearable device based on at least one output from the at least one sensor, or send the at least one output to the monitoring system via the communication interface; and output, after the harm is determined to be possibly occurring, an alarm based on receiving confirmation from the user, or based on not receiving any confirmation from the user within a predetermined amount of time.

An electronic device includes a short-range wireless communication circuit that performs first short-range wireless communication based on a first protocol and second short-range wireless communication based on a second protocol, and a processor that connects the first short-range wireless communication with a peripheral device through the short-range wireless communication circuit, transmits a service discovery frame including service information associated with the peripheral device to devices included in a cluster configured to include the electronic device through the second short-range wireless communication when a trigger event occurs, establishes a wireless data communication path with an external electronic device, which transmits a message in response to the service discovery frame to the electronic device through the second short-range wireless communication, from among the devices included in the cluster, and transmits input information received from the peripheral device through the short-range wireless communication circuit or control information corresponding to the input information to the external electronic device through the wireless data communication path.

This invention is a wearable device which helps a person to track their food intake as part of a system for nutritional intake monitoring and management. This invention can be embodied in a smart watch and/or wrist band with a camera, a display and/or camera viewfinder, a spectroscopic sensor, and an eating detector. The eating detector can be an accelerometer, a gyroscope, a magnetometer, a microphone, or an EMG sensor. The camera and/or the spectroscopic sensor can be automatically activated when the person eats food, but otherwise remain off to help maintain privacy.

The embodiments of the invention provide a signal transmission method and apparatus. The method comprises: a first apparatus determines a bandwidth and a quantity of subcarriers of a target channel, wherein the bandwidth and the quantity of the subcarriers of the target channel are determined according to a level and/or a type of terminal equipment using the target channel; and the first apparatus transmits, according to the bandwidth and the quantity of the subcarriers of the target channel, via the target channel, and to a second apparatus, a signal, or receives a signal sent from the terminal device via the target channel, wherein at least one of the first apparatus and the second apparatus is the terminal equipment. The embodiment of the invention can prevent resource wastage.
