摘要： Apparatus and methods for adjusting the video display controls in a multi-frequency video display include an EEPROM that stores multiple sets of video display parameters for the video display. A microcontroller receives input from a user, changes the stored display parameters and outputs changes in the parameters to the video display. The microcontroller also controls video display apparatus that displays on-screen menus and value indicator graphs for facilitating user input. The video display apparatus incorporates a video clock synchronized to the horizontal synchronization signal of the multi-frequency display, to keep the displayed menus synchronized regardless of the current frequency. In addition, the video display apparatus elongates displayed characters at higher frequencies to control the absolute size of displayed characters across frequencies. The present invention provides for changes to video display parameters, and for resetting the display parameters to factory standards, without manipulating electromechanical devices such as potentiometers.

摘要： A keyboard membrane keyswitch assembly comprises a housing (13), a button (11), a compression piston (12) and a rubber element (14). The housing (13) holds the compression piston (12) and the rubber element (14). The compression piston (12) has a cylindrical shape with a vertical guider (121) along its longitudinal axis. The vertical guider (121) is used to connect the assembly to the button (11). A supporting ring (122) is linked to the vertical guider (121) by rib elements (123). The rubber element (14) is adapted to receive the supporting ring (122) of the compression piston (12) thereby maximizing the displacement of the button (11) and preventing the button from tilting when it is depressed.

摘要： A keyboard switch for use with a membrane switch array (20) to provide a tactile feeling and, optionally, a click sound comprises a housing (10) which is positioned on the membrane switch array (20). A plunger (13) is reciprocally mounted within the housing (10) and projects outwardly from the housing, the plunger having a cam portion (133). An actuating arm (14) is pivoted to the housing (10) and has a first portion (141) extending beneath the plunger (13) and a second, cam follower portion (142) which engages the cam portion (133) of the plunger (13). The first portion (141) of the actuating arm (14) has a boss (1412) on its surface facing away from the plunger (13) for engaging the switch array (20). A compression spring (15) extends between the plunger (13) and the first portion 141 of the actuating arm (14) to urge the plunger (13) outwardly from the housing (10). A leaf spring (16) is mounted to the housing (10) and has a portion (161) which normally engages the plunger (13) whereby when the plunger is depressed into the housing (10) the boss (1412) on the actuating arm actuates the membrane switch and the plunger flexes the leaf spring to a point at which the spring snaps back to a rest position thereby providing a tactile feeling and, in certain cases, a click sound.
