ALPS USB Keyboard

Windows device driver information for ALPS USB Keyboard

The ALPS USB keyboard device features ALPS’ advanced mechanical key switches and a comfortable ergonomic design. This USB keyboard device is fully compatible with the USB 1.1 specification. This device also makes use of ALPS’ simulation technology for achieving a completely comfortable and effective key touch. For keyboards to implement comfortable key operations, it is vital that the key touch hysteresis property, peak load and stroke have to be perfectly balanced. To address this issue, ALPS has optimized the rubber dome form used in the ALP USB keyboard by making use of simulation records from FEM analysis, 200 plus trial data and CAD technology. A keyboard contains a processor and circuitry. This circuitry is responsible for carrying information from and to the keyboard’s processor. A great portion of the circuitry comprises the key matrix. This key matrix is made up of circuits in a grid that is located under the keys.

In every keyboard with the exception of capacitive model type keyboards, every circuit is broken at a portion under every key. When users press a particular key, it will in turn press a switch which will complete the circuit and enable a small amount of current to pass through. The mechanical operation of the switch will cause a kind of vibration known as the bounce that will be filtered out by the keyboard’s processor. Pressing and holding a key will result into the processor recognizing the action as the equivalent of a key that is being repeatedly pressed. In the event that the processor identifies a closed circuit, it will compare the position of the closed circuit on the key matrix to that of the character map located in its ROM (read only memory). It is highly recommended you run a free registry scan for and ALPS USB Keyboard errors before installing any driver updates.
