A method of communication in an elevator operating environment is provided. The method includes generating a Bluetooth low energy (BLE) distinguishable signal with a wireless signal generating device located in at least one location proximate to an elevator boarding area. The method also includes receiving the BLE signal with a mobile device when the mobile device is proximate to the wireless signal generating device. The method further includes initiating an elevator call with the mobile device. The method yet further includes initiating the mobile device to enter a connection mode with a BLE access point device.

A method for improving the alignment of the bi-directional scan lines of a resonant mirror imaging system is disclosed. The method includes sensing the position of the mirror and selecting a portion of each scan line, such as the exact middle 50% and the start points of the scan lines in both directions for displaying the image. Determine the specific number of pixels used to modulate the scan lines and the clocking rate at which the pixels are inserted on the light beam so that the pixels completely fill the selected portion of the scan lines. The clock rate is then adjusted to the determined rate.

Method to improve scan-line alignment by adjusting the pixel rate

System and method for synchronizing the low speed mirror movement of a mirror display system with incoming frame or video signals, and synchronizing buffered lines of video data to the independently oscillating scanning mirror. According to one embodiment of the invention, the peak portions of the low speed cyclic drive signal are synchronized with the incoming frames of video by compressing or expanding the peak portion or turn around portion so that each video frame begins at the same location on the display screen. The actual position of the high frequency mirror is determined by sensors and a 'trigger' signal is generated to distribute the signals for each scan line such that the scan lines are properly positioned on the display.

Method for maintaining the phase difference of a positioning mirror as a constant with respect to a high speed resonant mirror to generate high quality images

Method for synchronizing an image data source and a resonant mirror system to generate images

A mirror display system comprising a multiplicity of scan lines that are combined to generate an image. The multiplicity of scan lines are orthogonally positioned in response to a slow speed cyclic drive signal (for example, sinusoidal or repetitive triangular shape). To increase the brightness of the display, and unlike a typical raster scan display, scan lines are generated during both the positive going portion and the negative going portion of the cyclic drive signal.

Method for aligning bi-directional images in a mirror display

A method for aligning consecutive scan lines of a mirror based visual system produced by the bi-directional scan of a resonant mirror is disclosed. The actual position for the mirror is determined or measured by any suitable method. The measured position of the mirror is used to generate a first trigger signal to start a scan line in a first direction at a selected location and to generate a trigger to start a scan line in the reverse direction at a second location.
