  • Patent number: 7332688
    Abstract: Control mechanisms and methods of use include the use of active materials as a blocking element. The control mechanisms generally include a tactile control in operative communication with an electrical circuit, wherein actuation of the tactile control closes the electrical circuit to activate a function. The blocking element includes an active material that is intermediate to the electrical circuit and the tactile control. The active material is adapted to change at least one attribute such as a modulus property in response to an activation signal. The change in the at least one attribute selectively changes a force level for actuating the tactile control.

  • Patent number: 7326870
    Abstract: A key module and its manufacturing method are provided in the present invention. The steps of the method include: providing a mold; forming a key body having multiple opening portions on the mold; jostling a combination of a display body and an elastic body to the key body; and finally, tightly attaching the display body to the key body and stuffing the display body into the opening portions of the key body. Therein, the elastic body has a lower end formed with a contact block contacting a circuit board. By compressing, injecting or infusing a silicone rubber material or an elastic material into the opening portions, the gap located between the key body and the display body or between the key body and the elastic body is smaller than 0.01 mm. Thus, the appearance of the key module of the present invention is almost seamless.

  • Patent number: 7326869
    Abstract: A tactile feedback switching mechanism having a plurality of switching states. The tactile feedback switching mechanism includes a plunger switch having a plunger. When the plunger is displaced a given distance the switch changes state. A covering lies at least over the plunger switch and includes a border section and a deformation section. The covering may be formed from an elastic material such as an elastomer. When a user depresses the plunger, confirmation of a change in the state of the switch can be tacitly sensed by a change in resistance provided by the covering. The resistance of the covering changes by deformation of the deformation portion of the covering while the plunger is depressed.

  • Patent number: 7205492
    Abstract: A push button actuator unit has a housing which defines a through passage that extends along an axis of the housing, and a slot that extends in a plane which transversely intersects the axis and communicates with the passage for supporting in the housing-defined slot a disc-shaped member having a central opening that aligns with the passage. Movable in the aligned passage and opening is a push button sub-assembly of the unit which includes a front element that, when depressed rearwardly, may cause a rear element of the push button sub-assembly to extend rearwardly from the housing to release a latch or to operate a switch or the like. If the unit is to be lockable, an optional locking mechanism is added to the elements of the push button sub-assembly to selectively drivingly connect the front and rear elements so that depression of the front element will cause rearward extension of the rear element only when the unit is unlocked.

  • Patent number: 7199320
    Abstract: A first bearing member is provided on one of an upper face of a board member and a lower face of a key top member. A first guide member is provided on the other one of the upper face of the board member and the lower face of the key top member. A first link member is disposed between the board member and the key top member, and has a first end portion rotatably supported by the first bearing member and a second end portion engaged with the first guide member. The first link member is pivotable in a first direction about the first end portion thereof to allow the key top member to move in a vertical direction. The second end portion of the first link member is slidable relative to the first guide member in a horizontal direction in accordance with the movement of the key top member.

  • Patent number: 7180024
    Abstract: An operating device includes a switch member having a shaft holding part for holding a base end of a shaft member, an operating member having a mounting part formed in a substantially cylindrical shape which is adapted to be engaged with an end portion of the shaft member, and a stopper member which is engaged for mounting with the mounting part. The stopper member restricts relative movement of the shaft member in a state where a gap is left for permitting displacement of the shaft member in an axial direction, and releases the restriction when a load beyond a predetermined load in the axial direction of the shaft member is applied and locking members is deformed, thus permitting relative movement of the operating member with respect to the shaft member.

  • Patent number: 7164088
    Abstract: A keyboard for an electronic device that incorporates a flexible carrier for the keys. The flexible carrier has cutouts or slots that aid in decoupling the actions of one from its neighbors. Moreover, in addition to or instead of cutouts or slots, the flexible carrier optionally has cutouts around its outer perimeter. In some embodiments, the keys are molded as part of the flexible carrier. In other embodiments, the keys are attached to or inserted in the flexible carrier during manufacture. Various embodiments of the invention employ various key shapes to aid the user's tactile experience while typing.

  • Patent number: 7157655
    Abstract: In an embodiment, a keyboard includes a barrier layer. The barrier layer may be mounted between an upper and lower housing portion of the keyboard so as to provide a substantially water impermeable pocket about a keyboard circuit. The barrier layer includes at least one key aperture that allows the barrier layer to attach to a key, the attachment providing a substantially water impermeable seal between the barrier layer and the key. Thus, the barrier layer acts to prevent liquids that are spilled on the keys from contacting and damage an electrical keyboard circuit provided below the barrier layer. In an embodiment the keyboard may be rinsed under running water without damaging the keyboard circuit.
