Abstract
A computer system includes a wireless keyboard, a reader, and a computer. The wireless keyboard includes an antenna, an array of keys, a storage unit, a scanning unit, and a processing unit. The keys in the array are associated with tags. The storage unit stores a content of a pair of tags of each key. The scanning unit scans the keys to determine when one or more keys are pressed. When one or more keys are pressed, the processing unit acquires the tag content corresponding to each of the one or more keys and sends the content to the reader.
Claims8
A wireless keyboard comprising:
- an antenna;
- a key array, comprising a plurality of keys arranged in a matrix manner and a plurality of tags each connected to a row or a column of the keys, and each of the keys connected to a first and a second tags respectively connected to a corresponding row and a corresponding column the key belongs to;
- a storage unit to store a tag content of each key associated with the first tag and the second tag;
- a scanning unit to scan all keys in real time and determine whether one or more keys of the keys are pressed, and when one or more keys are pressed, to read signals from the first tag connected to the corresponding row and the second tag connected to the corresponding column of each of the one or more keys and generate a scanning signal;
- and
- a processing unit to acquire a tag content corresponding to each of the one or more keys from the storage unit according to the scanning signal and send the tag content of each of the one or more keys as a radio signal via the antenna.
A computer system comprising:
- a computer;
- a reader;
- and
- a wireless keyboard further comprising:
- an antenna;
- a key array, comprising a plurality of keys arranged in a matrix manner and a plurality of tags each connected to a row or a column of the keys, and each of the keys connected to a first and a second tags respectively connected to a corresponding row and a corresponding column the key belongs to;
- a storage unit to store a tag content of each key associated with the first tag and the second tag;
- a scanning unit to scan all keys in real time and determine whether one or more of the keys are pressed, and when one or more keys are pressed, to read signals from the first tag connected to the corresponding row and the second tag connected to the corresponding column of each of the one or more keys and generate a scanning signal;
- and
- a processing unit to acquire a tag content corresponding to each of the one or more keys from the storage unit according to the scanning signal and send the tag content of each of the one or more keys as a radio signal via the antenna;
- wherein the reader receives the tag content of each of the one or more keys and the computer processes the tag content and performs a function corresponding to the key.
