摘要： Methods and systems for efficiently embedding information in a keyboard membrane. Information can be embedded in the keyboard membrane by integrating an information embedding circuit with a switch matrix used to identify location of a key press event. The information is embedded by either hardwiring a column to a selected row, or a row to a selected column. In order to access the embedded information, the row (column) is asserted resulting in the hardwired column (row) to also be asserted. The identification of the asserted column (row) is used to point to the embedded information.

摘要： Methods and systems for providing stable and accurate low noise DC reference voltage are described. In the described embodiments, a feedback controlled DC reference voltage supply provides a stable and well controlled sense current. The sense current is in turn used to produce a stable and well controlled light output from a light emitting diode (LED).

摘要： The present invention can include three-dimensional remote control systems that can detect an absolute location to which a remote control is pointing in first and second orthogonal axes and an absolute position of the remote control in a third orthogonal axis. Remote control systems of the present invention can employ absolute position detection with relative position detection. Absolute position detection can indicate an initial absolute position of the remote control and relative position detection can indicate changes in the position of the remote control. By combining absolute and relative position detection, remote control systems of the present invention can track remote controls more precisely than systems that only employ absolute position detection. The present invention also can include methods and apparatus for zooming in and out of an image shown on a display based on the absolute position of the remote control in the third axis.

摘要： Remote control systems that can distinguish predetermined light sources from stray light sources, e.g., environmental light sources and/or reflections are provided. The predetermined light sources can be disposed in asymmetric substantially linear or two-dimensional patterns. The predetermined light sources also can output waveforms modulated in accordance with one or more signature modulation characteristics. The predetermined light sources also can output light at different signature wavelengths.
