| 103 | Pressure sensitive functionality for keyboard keys | US10236191 | 2002-09-05 | US06758615B2 | 2004-07-06 | Patrick Monney; Jean-Marc Flueckiger; Denis Pavillard; David Lee Sandbach |
| Embodiments of the present invention are directed to a computer keyboard having a key sensing device that provides two levels of sensing by generating electrical signals depending on the force applied on the keys. The different levels of key sensing can be used to provide different functions, for instance, in a software application. This key sensing functionality can be provided on all or only some of the keys of the keyboard. For example, the different pressure levels applied on the key can be used to control cursor movement or scrolling and to produce pressure-based shifting between lower case and upper case. A method of providing pressure sensitive key functionalities for a keyboard comprises producing a signal by applying a pressure to a key which is configured to produce different signals in response to different pressure levels applied to the key. A user interface response is generated based on the signal produced by the pressure applied to the key. The different signals are adapted to generate different user interface responses for the key. | ||||||
| 104 | Multidirectional control switch and multidirectional input device using the same | US10642672 | 2003-08-19 | US20040080395A1 | 2004-04-29 | Hiroyasu Okada; Masaki Sawada; Hiroto Inoue; Tamotsu Yamamoto |
| A multidirectional control switch of the present invention is used in a variety of electronic apparatuses including a portable telephone and a personal digital assistant. A first switch contact of this switch outputs a first signal continuously varying as a top surface of a substantially disc-shaped operating member undergoes a sliding press along a locus substantially in arc form. With a stronger press, a second switch contact outputs a second signal. The multidirectional control switch has a simple structure and can be reduced in size because these two switch contacts are integrally formed, eliminating the need to combine discrete elements. | ||||||

| In a pressure sensor, a first contact electrode is formed on a base board. A second contact electrode is formed on the base board such that a top face thereof is made flush with a top face of the first contact electrode. A deformable click rubber has a flat bottom face opposed to the first and second contact electrodes. The flat bottom face is in parallel with the top faces of the first and second contact electrodes.

Such a multi-stage switch can be produced cost-effectively with simple structural means, can be universally used, is easy to operate, maintenance free to the greatest extent and operates dependably. | ||||||
| 114 | Rocker member actuated switch assembly | US762399 | 1996-12-09 | US5753874A | 1998-05-19 | Thomas Kossakowski |
| A multi-stage electrical rocker actuated switch assembly is disclosed which basically consists of a rocker operating element which is pivotably mounted on a housing and four plungers which face the underside of the rocker operating element with one of their ends while the other ends engage with a movable contact part. In order to create a multi-stage rocker actuated switch in which two exactly definable functional positions in each direction can clearly be felt by the user because of a sharp change in the operating forces during operation of the rocker operating element, the two movable contact parts present in each functional group are so different in design that in order to switch over the one movable contact part, a force is necessary whose magnitude is definable different from the force which is necessary to switch over the other movable contact part and wherein for each functional group an intermediate element in the form of a two-armed lever is present which is situated between the ends of the two plungers belonging to each functional group and the underside of the rocker operating element, both intermediate elements being capable of displacement in the operational direction of the rocker operating element while at the same time they are mounted to as to be capable of tilting crosswise relative to the operational direction of the rocker operating element. | ||||||
| 115 | Sequentially operated membrane switches | US680623 | 1996-07-17 | US5717176A | 1998-02-10 | Jonathan Dahlstrom |
| An improved membrane switch includes multiple detents. A pair of electric circuits are completed by the membrane switch, and a pair of flexing portions are located on said membrane. A first flexing portion is overcome by a first lower insertion force to allow a first circuit to be complete, and a second flexing portion is only overcome by further insertion force. The second flexing portion is eventually overcome and completes a second circuit. The inventive membrane switch provides the operator with a clear indication and a detent feel for each of the two circuits. | ||||||

The two-stage movement seesaw switch includes a pair of operation plates disposed immediately below a manually operable knob. Two sets of push switches, each set including two push switches, are disposed such that a straight line interconnecting the push switches of each set extends obliquely with respect to a center axis of pivotal motion of the manually operable knob.

Each of the operation plates has an opening formed therein for passing light emitted from an LED therethrough and has a pair of projections formed thereon next to the opening. | ||||||
| 117 | Switch actuating mechanism for two sequentially activated switches | US639355 | 1996-04-26 | US5672857A | 1997-09-30 | Richard L. Frost; Edgar C. Kolb; James S. Robinson |
| A switch actuation mechanism is provided with a support structure that is shaped to hold two switches. Each switch is associated with a pivotable member that is rotatably attached to the support structure. The pivotable member can be moved into either a rest position or an actuating position. When in the rest position, an actuating surface of the pivotable member is placed in contact with a plunger of the associated switch. A resilient member, such as a spring, is used to urge the pivotable members into their rest positions. If an actuator, such as a plunger or latch, is move into contact with a protrusion extending from the pivotable member, the pivotable member is rotated clockwise and the actuating surface is moved out of contact with the plunger. This deactuates the switch. The two switches are arranged to provide a sequential deactuation as two actuators are moved into contact with their respective protrusions extending from the pivotable members. | ||||||
