New techniques are presented for providing proportional activation of model railroad functions with control keys. This permits for example a compact throttle device connected to a digital layout control system to provide for a "playable" or variable-pitch whistle sound effect where prior art was severely limited in providing this effect realistically. This invention allows multiple proportional keys in a cost-effective manner that is compatible with existing keyboard designs.

There is provided an electric keyboard assembly having a construction which is capable of reducing a height of a keyboard and at the same time facilitating key scaling to key-touch response while maintaining the degree of freedom in designing the keyboard. A key is pivotally moved by a key depressing operation. A seesaw-type mass member having a front extension and a rear extension each extending from a pivot-receiving portion thereof, and a tone-generating position adjustment screw fitted in the front extension is pivotally moved about the pivot-receiving portion by a driving force generated by depression of the key and received via the tone-generating position adjustment screw. The front extension of the mass member pops up to a level higher than the key when the key is depressed. A front weight and a back weight are arranged separately in the front extension and in the rear extension, respectively. A distance between the pivot-receiving portion and the front weight arranged in the front extension is set to be shorter than the distance between the pivot-receiving portion and the back weight member arranged in the rear extension.

The invention provides a keyboard controller which comprises a master module based on an MCU (microprogrammed control unit) and a slave module designed based on a CPLD (complex programmable logic device); a master communicates with a slave through a bus; the slave detects every key of an independent keyboard by adopting CPLD device design, implements shake elimination processing and also outputs an LED (light emitting diode) control state; each IO (input/output) interface of the slave can be designed to be a key detection port or an LED state output port; a reserved IO interface can be used for freely and selectively increasing or decreasing a key or an LED; the master communicates with the slave through the bus to acquire key information of the independent keyboard and controls the slave to output the state; furthermore, the master encodes the keys to realize a function of a protocol layer and sends codes to a computer through an USB (universal serial bus) interface and a PS2 (play station 2) interface. Keyboard designs with different distributions and different functions can be realized by increasing or decreasing the number of the slaves; the master can change the function and the code of each IO of each slave by modifying firmware of the master.

The invention relates to a method for generating a global positioning system (GPS) synchronous control signal suitable for electromagnetic method detection, which is used for the synchronization of the generation of the current of an electromagnetic method based transmitter and the reception of the signal of a receiver and suitable for the fields of geophysical exploration, engineering geological exploration, and the like. The invention adopts the technical scheme as follows: the transmitter and the receiver receive GPS clock information and second pulse signals, determine a time reference point and calculate sending signal synchronous control starting time, and start the output current of the transmitter through the second pulse narrowing signals when the clock is equal to the sending signal synchronous control starting time. The method has the advantages that the method can eliminate the setting of the synchronous control starting time; for a mixed field source transmitter not required for setting a sending current parameter, the method can omit the keyboard design and simplify the system with reliable use; and for other types of electromagnetic transmitters, a frequency selective switch is only needed to set a frequency, and the operation is quite convenient. The invention is also suitable for occasions where a plurality of transmitters are connected in series and in parallel and a plurality of receivers are combined for use.

There is a need to develop a more sophisticated and educational system of keyboard set ups for not only the disabled population from their worker's compensation injuries but for the entire continuum of keyboard users nationally and internationally. This is due to the rising medical costs associated but also for the days out of work as the Bureau of Labor Statistics report for upper extremity sprains and strains and more importantly, carpal tunnel syndrome. Design companies are making ergonomic changes in the mouse, keyboard design but not until now has a long term solution been invented. Smart businesses are not waiting for regulation or lawsuits to prompt action geared to preventing such repetitive motion injuries such as carpal tunnel syndrome. The dual system of keyboard/keypad, mouse or calculator set ups after training will have a decided impact on the reduction of computer related work force injuries or to provide dexterity training for other people with disabilities.

Embodiments of a backlit keyboard assembly are described. A keycap assembly is mounted into a case web having intersecting ribs.
