A digicational smart book for facilitating providing education to a user includes a front cover comprising a first receptacle for receiving a front screen. Further, the digicational smart book may include a rear cover comprising a second receptacle for receiving a rear screen. Further, the digicational smart book may include an input device configured to receive a request from a user. Further, the digicational smart book may include a spine comprising a processing device configured for processing the request. Further, the spine may include a storage device configured for retrieving an educational module and a communication device configured for transmitting the educational module to the front screen and the rear screen. Further, the digicational smart book may include a power source configured to provide electrical energy to the front screen, the rear screen, the communication device, the processing device, and the storage device.

A mute-able input device with keystroke tactile feedback includes: a plurality of keys, each including a tactile structure and a sound-generating structure for respectively generating operational tactile feedback and operating sounds; a plurality of adjusting mechanisms, each including an adjusting portion corresponding to one of the keys; at least one switching unit including an operating portion and a switch member, the operating portion connecting the switch member and the adjusting mechanism, the switch member generating a switching signal involving a mode switching between different tactile modes or different sound modes for one or more keys. When the operating portion moves in response to a force, the switch member is triggered to achieve the mode switching; meanwhile, the adjusting portion moves to interfere with at least one of the tactile structure or the sound-generating structure along with the movement of the operating portion.

A shelf bracket is provided. The shelf bracket includes a shelf member and opposing side flanges extending from a back plate. A front flange extends from each of said opposing side flanges. The back plate, shelf member, side flange, and front flange define a cavity configured to receive an enclosure, such as by moving the enclosure in a vertical direction in and out of engagement with the cavity. The shelf member defines a bottom limit of the cavity such that movement of the enclosure into the cavity is limited to a first vertical direction and movement of the enclosure out of the cavity is limited to a second vertical direction, the second vertical direction being diametrically opposed to the first vertical direction. A support flange is optionally included, which is configured to engage with a support structure so as to provide support for the shelf bracket.

Methods and apparatus provide for: generating image data for an application to be displayed on an output device; recording the image data generated by the image generating unit; and receiving operation information from an input device, where the recording includes storing the image data for an application for a predetermined period of time up to the point in time at which operation information is received during the receiving operation information from a specific input unit provided in the input device while displaying an application image.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

A wearable device includes a wearable device main body, a sensor part configured to contact a skin surface of a user of the wearable device, and measure a bio-signal of the user, and a shock absorber that is interposed between the wearable device main body and the sensor part to mechanically connect the wearable device main body and the sensor part, and that is configured to reduce motion transmission between the wearable device main body and the sensor part to permit the wearable device main body to move independently from the sensor part.
