A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

A method for adjusting an optical switch keyboard and an optical switch keyboard using the adjusting method are provided. The optical switch keyboard has a number of key units. The method includes the following steps. A scan signal is applied to one of a number of scan lines by a control unit at a first scan time point. A light is emitted by a light source according to the scan signal. A light emitted by the light source is detected by a detecting element to generate a detecting electric signal. The detecting electric signal is read by the control unit to obtain a first read signal voltage. When the first read signal voltage is outside the voltage range of the pressed state of the key unit, the period of the scan signal is increased by a first predetermined amount by the control unit to obtain an adjusted scan signal.

A keyboard having multiple layouts includes depressible keys. A light reflector is positioned under at least some of the depressible keys with light sources configured to emit light towards the light reflectors. The light impinges on one of a plurality of reflective surfaces of the light reflectors and is reflected towards a corresponding depressible key under which the light reflector is positioned to cause a character or symbol to appear on a surface of the depressible keys. A switch allows a user to selectively control the character or symbol appearing on the surfaces of the depressible keys, resulting in more efficient input for the multiple layouts that improves the user experience.

An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The light-emitting die package is disposed to illuminate the keycap through the base plate. The light-emitting die package comprises a warm color temperature light-emitting die and a cold color temperature light-emitting die, and the light-emitting dis package extends along an arrangement direction. Each of the two light-emitting dies has a short side arranged adjacent to each other, with a long side of each of the two light-emitting dies facing a same direction and configured proximate to each other. A gap between the two adjacent short sides of the two light-emitting dies is not greater than either one of the two adjacent short sides of the two light-emitting dies.

Example methods and apparatuses of controlling a user interface with a plurality of input mechanisms are disclosed. One example method includes causing a first set of input mechanisms in the plurality of input mechanisms to be visually emphasized via a first visual technique while a second set of input mechanisms in the plurality of input mechanisms is not visually emphasized via the first visual technique, receiving a user input via an input mechanism that is included in the first set, based on the user input, determining a third set of input mechanisms in the plurality of input mechanisms and a fourth set of input mechanisms in the plurality of input mechanisms, and causing the third set of input mechanisms to be visually emphasized via the first visual technique while the fourth set of available input mechanisms is not visually emphasized via the first visual technique.

An illuminated pushbutton for a pushbutton switch having a light transmitting pushbutton and an indicia cover that is attached to a front end of the light transmitting pushbutton. The indicia cover has non-light transmitting regions and light transmitting regions on its front surface, wherein the light transmitting regions provide visible, light-transmitted indicia on the light transmitting pushbutton. The indicia cover has an adhesive on its rear surface to attach the indicia cover to the front end of the light transmitting pushbutton. An LED in the pushbutton switch is constructed to transmit light to the indicia cover. The light passes through the light transmitting regions (symbols and letters) but not through the non-light transmitting regions. As the light passes through the light transmitting symbols and letters, the symbols and letters are lighted and visible in the dark.

At each step of a workflow performed by an operator that involves a plurality of input mechanisms in a radiation therapy system, the operator is assisted in the process of selecting the next input mechanism in a way that greatly reduces the number of possible input mechanisms that can be chosen. A first subset of input mechanisms is made visually prominent via a first visual technique and a second subset of the input mechanisms is made visually prominent via a second visual technique. The first subset includes input mechanisms that are available for selection at that particular step in the workflow and the second subset includes recommended input mechanisms that are the most likely to be the next input mechanism that should be actuated by the operator at that particular step in the workflow.

A keyboard having multiple layouts includes depressible keys. A light reflector is positioned under at least some of the depressible keys with light sources configured to emit light towards the light reflectors. The light impinges on one of a plurality of reflective surfaces of the light reflectors and is reflected towards a corresponding depressible key under which the light reflector is positioned to cause a character or symbol to appear on a surface of the depressible keys. A switch allows a user to selectively control the character or symbol appearing on the surfaces of the depressible keys, resulting in more efficient input for the multiple layouts that improves the user experience.

Touch sensitive mechanical keyboards and processes for detecting touch events and key depressions on the touch sensitive mechanical keyboard are provided. The touch sensitive mechanical keyboard can include a set of individually depressible mechanical keys having a touch sensitive surface. A touch sensor layer can be disposed on top of a key mechanism and flexible interconnections provided between key segments of the touch sensor layer can allow for depression of the key mechanism of individual keys. In some examples, the flexible interconnections can be formed by patterning a spring-like structure into the touch sensor layer. In some examples, the touch sensor layer can be transparent or include openings to allow a backlight to shine through. In some examples, addressable LED backlighting with buckling interconnects can also be provided to illuminate keycaps of the mechanical keyboard.

An input device is provided which includes: a first light source which emits light to cause a first design to be displayed on a display region: a second light source which emits light to cause a second design different from the first design to be displayed on the display region; a switch which receives an input from a user; and a control circuit which, according to the input received by the switch, (i) controls displaying of a design on the display region, by controlling a lighting state of the first light source and a lighting state of the second light source, and (ii) outputs a control signal corresponding to the input received by the switch, to an external device.
