Techniques and apparatus to provide improved visibility to user input devices, such as keys, are disclosed. In low light conditions, keys can be difficult to distinguish. For example, often keys have legends on them to visually distinguish them from one another, but in low light conditions it can be difficult for users to visually distinguish the different keys. The legends can be textual and/or graphic. Hence, according to one embodiment, light from a nearby display device can be used to provide illumination to the user input devices (e.g., keys). More particularly, in one embodiment, some light from the nearby display device can be directed towards and reflected from the user input devices (e.g., keys) to enhance visibility of the keys or the legends thereon.

The invention discloses a method for determining a first-order echo spectrum boundary and a second-order echo spectrum boundary of high-frequency ground wave radar based on an azimuth angle, and belongs to the technical field of marine environment monitoring of the high-frequency ground wave radar. The first-order echo spectrum boundary and second-order echo spectrum boundary determining method isbased on the following characteristics of azimuth angles of ocean echoes: 1, for the first-order echoes, the closer the Doppler frequency is, the closer the azimuth angles of frequency points are; 2,in the vicinity of the boundary of the first-order echo spectrum and the second-order echo spectrum, along with the transition of a signal from a first-order echo signal to a second-order echo signal, the change trend of the azimuth angle of the signal is opposite to the change trend of the azimuth angle in the first-order echo spectrum; and 3, as long as a second-order spectrum exists in the echo spectrum, the two characteristics do not change along with the change of the sea condition. Therefore, the boundary of the first-order echo and the second-order echo can be determined by analyzing the azimuth angle of each frequency point between a first-order Bragg peak and a second-order singular peak. Compared with an existing method, the method has the greatest characteristic of being suitable for different sea condition conditions.
