A backlight apparatus includes a light-guiding plate, a light-shielding membrane, a light-reflecting sheet, a plurality of first translucent glue bodies, and a plurality of second translucent glue bodies. The light-guiding plate has a plurality of through holes. Each of the first translucent glue bodies corresponds to one of the through holes. Each first translucent glue body is placed on a front surface of the light-guiding plate, and surrounds a respective circumference of the corresponding through hole to bond the light-shielding membrane thereabove and the light-guiding plate therebelow. Each first translucent glue body has a respective breach. Each of the second translucent glue bodies corresponds to one of the first translucent glue bodies, is placed via at least one portion thereof in the breach of the corresponding first translucent glue body, and bonds the light-shielding membrane thereabove and the light-guiding plate therebelow.

A backlight module includes a circuit board, a light-shielding plate, and a light guide plate. The circuit board is provided with first and second light-emitting units. The light-shielding plate is disposed above the circuit board. The light guide plate is disposed between the circuit board and the light-shielding plate and includes first and second single-key light guide areas. The first and second single-key light guide areas respectively have first and second through holes respectively accommodating the first and second light-emitting units. A distance between the geometric center of the first single-key light guide area and that of the light guide plate is greater than a distance between the geometric center of the second single-key light guide area and that of the light guide plate. A current flowing through the first light-emitting unit is greater than a current flowing through the second light-emitting unit.

An information handling system and keyboard automatically coordinate wireless pairing when the keyboard couples to the information handling system to interface contacts exposed at the information handling system housing and the keyboard. The information handling system retrieves an identifier of the keyboard through a contact, determines if the keyboard is already paired, and if not initiates wireless pairing with a command through the contact. A pairing key is provided from the keyboard to the information handling system through the contact and applied by the information handling system to complete pairing. A confirm code is communicated through the contact to the keyboard for communication back to the information handling system by wireless signals. The contacts provide a charging path to charge the keyboard when coupled to the information handling system.

An input apparatus includes a reflection layer, a light guide plate, a first light source, a second light source and a light absorption member. The light guide plate is disposed on the reflection layer and includes a first light guide region and a second light guide region connected with each other by a junction, a first area of the first light guide region is different from a second area of the second light guide region. The first light source corresponds to the first light guide region. The second light source corresponds to the second light guide region, the light guide plate has a first opening structure disposed between the first light source and the second light source. The light absorption member is disposed at a position corresponding to the first opening structure.

A mobile phone device includes a housing having a substantially rectangular shape wherein its height dimension substantially corresponds to a distance between an ear and a mouth of a user and wherein its width dimension is less than its height dimension. A display unit is integrated within the front surface of the mobile phone device. The display unit substantially entirely covers the front surface of the mobile phone device. The mobile phone device does not include a physical key on the front surface.

A system for training animals includes a hand-held device and a remote device, where the remote device applies a stimulus when a user presses a button or trigger on the hand-held device. The amount of pressure applied is measured by a pressure sensitive transducer and transformed into proportional transducer signals. These transducer signals are transmitted to the remote device, which then applies a stimulus to an animal being trained. The amplitude of the applied stimulus corresponds to the amplitude of the transducer signals; a trainer can thus precisely control the intensity of the stimulus by applying and relieving pressure on the button. The type of stimulus applied is controlled based on the position of a rotary switch on the hand-held device. Sensor data generated by specialized sensors in the remote device may be transmitted to the hand-held device to provide the user with sensory feedback.

A haptic switch can be used to control one or more display screens. In an example embodiment, the haptic switch takes the form of a flooring sample—such as a sample piece or swatch of a flooring material, for example, ceramic tile, wood, or carpet—that is affixed or otherwise mechanically coupled to an electronic sensor, such as a proximity sensor, a touch sensor, or a pressure sensor. The haptic switch is communicatively coupled to a machine, and the machine stores or is otherwise able to access a database that correlates the haptic switch or its included flooring sample to corresponding texture map data that depicts the flooring sample. The haptic switch is thus usable to select its corresponding texture map data and cause the machine to use the selected texture map data in generating video content and displaying the generated video content on one or more display screens.

A computer input device includes a housing having an opening, a ball holder supported relative to the housing and being concentric with the opening, a ball positioned within the ball holder and extending through the opening in the housing, and a scroll ring concentric with and rotatable relative to the ball holder. The ball is movable relative to the ball holder. The ball holder has a track, and the scroll ring has at least one projection received in the track of the ball holder to guide the scroll ring.

Embodiments of this application disclose a wireless charging system. The wireless charging system includes a first electronic device, a wireless charging device, and a second electronic device. The wireless charging device is located between the first electronic device and the second electronic device. The wireless charging device is an auxiliary device of the first electronic device and is physically connected to the first electronic device, the wireless charging device includes a receiver circuit and a housing, the receiver circuit includes a receiver coil, and the receiver coil is located on an inner side of the housing. The first electronic device is configured to: charge the wireless charging device, charge the second electronic device through the wireless charging device, and receive power from the second electronic device through the wireless charging device.

An electronic device with a slot antenna comprises a surface C, which includes a keyboard area for inputting using a keyboard, a touch area for inputting using a touchpad, and a palm rest. The palm rest is made of a metal material, and a radiating slot is disposed in the palm rest to form the slot antenna.
