A type of multimedia keyboard device, designed with two positioning depressions at the bottom of casing of a keyboard device, between said two positioning depressions is the formation of a separating unit, said positioning depressions and separating unit will be properly positioned between the user's thighs and on his lap, on one side or two sides of the casing is the design of a handgrip, at somewhere suitable for operation on the left and two sides of the casing is the design of press keys; so designed that it will be suitable especially for applications to wireless remote control keyboard, and will achieve such purposes that the keyboard may be positioned on the user's lap, may be held in both hands and its keys may be conveniently pressed.
An improved keyboard structure comprises a base, a pan body, and a top cover. A user is supposed to turn a turnable functional pushbutton to a specified function item, then click the pan body for the computer to execute the related program.
A keyboard has a middle region that has upward longitudinal slopes rising to upper planes on both sides of the middle region. An alphanumeric section disposed in the keyboard housing generally in the middle region. The keyboard includes a first wing section and the second wing section in which each can be disposed at height of the keyboard housing at the upper plane. In one aspect, the alphanumeric section may be disposed below the height of the first and second wing section, and the alphanumeric section is laterally disposed between the first medial section and the second media section.
The disclosed game keyboard device comprising: a key matrix, a direction control mechanism, and a microprocessor. A switch key is used to change the direction control mechanism between the functions of a joystick and a mouse. The game keyboard device can selectively implement the function of the joystick or mouse through a single direction control mechanism. Therefore, the hardware manufacturing cost of the game keyboard device can be considerably reduced.
A method for supporting a base of a laptop computer on a user's lap. The base may have a lower surface with two concave depressions that extend from a forward edge to a rear edge of the base. The depressions are spaced apart from one another and configured to receive a user's legs to support the weight of the laptop computer. In one embodiment, the depressions have roughness elements or a skid-resistant material. In another embodiment, support members extending outwardly from the base provide extra support for the base and/or further restrict motion of the base relative to the user's legs.
An apparatus and a method for entering data into a computerized navigation system of an aircraft is described. The device is strapped to the thigh with a connection provided to the aircraft avionics. To facilitate safety, quick release of the device from the avionics is provided. Alternatively, instead of a hard wired connection, a wireless connection is disclosed utilizing radio frequencies or infrared light. Alternatively, a pull away release is provided on the strap. The device consists of the keyboard that is ergonomically designed to provide one handed operation. Key layout on the keyboard is ergonomically designed to facilitate operation of the avionics being controlled. Backlighting of the keyboard provides illumination so that operation in low light conditions is possible. The keyboard may be equipped with a cover attached by a hinge that may be removed. The cover provides a convenient writing surface for the operator.
