Abstract:
A keyboard system having improved protection from electromagnetic interference includes a keypad and a printed circuit board assembly. The keypad includes one or more keys and one or more keypad conductive elements for at least one of the keys. The printed circuit board assembly is coupled to the keypad. The printed circuit board assembly includes a printed circuit board having at least one switch contact area for each of one or more keys on the keypad. The printed circuit board also includes, for at least one of the keys of the keypad, one or more first side vias in a switch contact area and one or more second side vias in the switch contact area. The first side vias are electrically coupled on a first side of a switch for the key. The second side vias are electrically coupled on a second side of the switch for the key.
Abstract:
Embodiments of the invention provide an effective keypad assembly and keypad layout for mobile computing devices. In particular, embodiments of the invention provide keyboard layouts and designs. Additionally, embodiments described herein provide for stack components to make keyboards 100 operable on small-form factor devices.
Abstract:
A keypad has both hill keys (12) that provide a corresponding output when individually pressed, and valley keys (14) are labeled to correspond with an output that results at least from the simultaneous or near-simultaneous manipulation of a predetermined set of two or more hill keys (12) adjacent the valley key (14). Pairs of hill keys (12) are joined to form elongated dual keys (16) that provide a nominal effective key width (H) substantially equal to a nominal effective key width (V) of the valley keys.
Abstract:
A keypad with both elevated (11) and non-elevated (22) key regions, and key switches (12) disposed beneath both types of key regions. The non-elevated key regions each provide corresponding character output based on an operation algorithm that considers activation of at least one adjacent elevated key region as well as activation of the switch below the non-elevated key region. The keypad includes a keymat (41) that is rigidly held at its perimeter in a stretched condition across a switch substrate (23). The key switches include metal snap domes (12) that have an elevated central region (212) forming a downwardly facing cavity (13) defined at its edge by a ridge (214) disposed above the switch contacts (21) that electrically engages multiple switch contacts in an annular contact zone (230).
Abstract:
A system, method and computer program product that permits a user, using the fingers of a single hand, to produce defined outputs such as generating characters for text input and executing commands. In a data processing system having plural input detectors, the invention comprises permitting the user to perform sequential gestures with the fingers of one hand to produce the defined outputs.
Abstract:
Ce dispositif électronique (10) comprend un clavier de saisie alphanumérique (14) et un gestionnaire de saisie (24) qui, en réponse à l'enfoncement d'au moins l'une quelconque des touches (28) du clavier de saisie (14), sélectionne un caractère alphanumérique (20) correspondant à ladite au moins une touche enfoncée. En outre, au moins un caractère alphanumérique (20) correspond à au moins une combinaison d'au moins deux touches (28) différentes enfoncées, et à chaque desdites au moins deux touches (28) enfoncées prise isolément correspond un caractère alphanumérique (20).
Abstract:
In one aspect, a telephone includes a keypad having a plurality of keys including a first array of keys carrying indicia representing numerical characters. At least two of the keys of the plurality carry indicia representing one or more diacritic marks.
Abstract:
An electronic device with a force sensing key (200) has a switch (280), a first force sensing region (290) for acquiring a first force value, a second force sensing region (290) for acquiring a second force value, and a processor for determining a selected function for the key (200) based upon the first force value and the second force value when the switch (280) is activated. The first force sensing pad (290) and the second force sensing pad (290) use a partially resistive material (250) that exhibits a force-to-voltage response value. By forming the switch (280) as a dome (225) switch, the force sensing key (200) provides crisp tactile feedback to a user. The force sensing key (200) can be configured for a variety of applications and user preferences by varying the architecture of the actuator (270).

Abstract:
A compact data entry system comprises functional zones (2) uniformly divided over an input surface and switches (6) organized in functional groups. Each functional group of switches (6) is associated with a functional zone (2). A functional zone (2) is activated when at least one of its associated functional groups is activated. The system further comprises a processing device (3). The processing device (3) detects the activation of said switches (6) and further detects the activation of a functional group of switches (6) after the member switches (6) of said functional group are activated. When activation of a functional group of switches (6) is detected, the processing device (3) activates a function corresponding to the activated functional group.
