A transmissive optical element is fabricated by filling a mold with molten liquid that includes a transparent plastic and a phosphor additive, and allowing the molten liquid to solidify to produce the transmissive optical element having phosphor dispersed therein. Accordingly, a separate phosphor coating or phosphor-containing encapsulant need not be used. Transmissive optical elements include a shell made of transparent plastic with a phosphor dispersed therein. The phosphor may be uniformly and / or nonuniformly dispersed in the shell.

A configurable computer input device. A base is operable to generate and detect a radio frequency carrier signal. A plurality independently positionable input members are each operatively positioned in the vicinity of the base and individually operable to modulate the carrier signal responsive to its identity and status.

A keypad assembly utilizes touch-detecting apparatus such as force sensors or touchpad assemblies for registering key presses. In exemplary embodiments, the keypad assembly is suitable for use in electronic devices such as a mobile telephones, calculators, hand-held computers, or the like, having single piece molded housings wherein the keypad assembly is at least partially encapsulated within the housing.

Disclosed is a multi-directional activation button disposed on a protective case for activating a multi-directional control device on an electronic device. The multi-directional activation button has a flexible membrane with a top side divided into directional surfaces that are aligned with a plurality of directions of operation of said multi-directional activation button. A membrane supports an extension that engages the multi-directional control device. The membrane has a length from a pivot point that controls the direction and the amount of movement of an activation extension wherein movement from the pivot point simulates an extension of a user's finger depending upon which directional surface of the rubber membrane is depressed by the user's finger. The multi-directional activation button may be utilized for push button activation, toggle slide operations, dial wheel, or joy stick like operations.

A keyboard and methods of making the same. The keyboard comprises of a bottom conducting base plate, an illumination layer, a transparent top conducting layer, a light transmissive keyboard membrane, and a plurality of input keys. The illumination layer is deposited on the bottom conducting base plate. The transparent top conducting layer is deposited on the illumination layer. The light transmissive keyboard membrane is disposed on the transparent top conducting layer. And, the plurality of input keys is disposed on the light transmissive keyboard membrane wherein each of the plurality of input keys has a keyswitch mechanism and a keycap including an upper strike surface attached to the keyswitch mechanism.

The method of selecting a light redirecting film or optical panel includes the steps of providing a length of film or substrate having a pattern of optical elements that varies, then selecting an area of the film or substrate that has a pattern of the optical elements that best suits a particular application, and removing the selected area from the film or substrate to provide the light redirecting film or optical panel. The pattern may be a repeating pattern that varies at different locations on the film or substrate and may comprise a roll of the film or substrate from which the selected area(s) is removed.

A button assembly applied on an electronic device is provided. An electronic device includes a housing and a button assembly. The housing defines two through holes and includes a first latching member. The button assembly includes a button body and a sealing frame. The button body includes two keycaps and a waterproof layer. Each of the keycaps extends through one of the through holes and is external to the housing. The waterproof layer is made of elastic waterproof material. The sealing frame includes a second latching member and is fixed to the housing. The waterproof layer corresponding to the first latching member and the second latching member is deformed, which creates waterproof seal.

A transmissive key sheet using translucent resin, which is capable of effective illumination while ensuring the thinness of the entire key sheet as well as suppressing a decrease in light transmission, input keys using the transmissive key sheet, and electronic equipment with the input keys. A transmissive key sheet of input keys comprises a first key sheet unit and a second key sheet unit, the opposite side of the first key sheet unit from key tops and the opposite side of the second key sheet unit from pressure applicators being bonded together with a translucent adhesive. The key tops made of translucent resin are molded integral with a translucent resin film having letters on its under surface to provide the first key sheet unit. The pressure applicators made of translucent resin are molded integral with a translucent resin film to provide the second key sheet unit. The light from a light source on a substrate illuminates keys so that the letters printed on the under surface of the translucent resin film become visible form outside. The pressing of each key top presses a corresponding key switch through the pressure applicator, and the key switch is concavely curved to make a contact with an electrode on the substrate. Thus, key input is provided.

A keyboard comprising a plurality of transparent keys. In use, the keyboard is attached to a device such as a mobile device, to overlie a display screen of the device. One or more images displayed on the display screen are made visible to a user through the keys, which may be pressed by a user. User input is determined by identifying a pressed key, and the image or part thereof visible through the key when pressed.

The present invention discloses a metallic linkage-type keying device, which is installed to a casing, such as the casing of a camera, a mobile phone or a video camera. The metallic linkage-type keying device of the present invention comprises: a metallic linkage, having at least two joining portions; and at least one key, having at least two assembling portions. The key is installed to the metallic linkage via fixing two assembling portions to two joining portions. The metallic linkage-type keying device provided by the present invention can prevent ESD from attacking the interior of the casing via key gaps and has the advantages of compactness and low cost.

The specification and drawings present a new apparatus and manufacturing method for optical protrusions (e.g., dome pins or actuators) attached to a light guide for providing backlight, actuation function and / or tactile feedback in keypad modules of electronic devices. Spatially and spectrally selective out-coupling of light from the light guide (e.g., a planar light guide plate) can be accomplished using these optical actuators integrated with the light guide for keypad illumination to control out-coupling efficiency and / or spectra of the out-coupled light to enable modification of the visual appearance (intensity, colored / white) of individual keys of the keypad.
