Abstract: A buffer arrangement for providing pixel information in a Lissajous scanning projection system is provided. The projection system includes a memory, a MEMS mirror, a projection unit, and a data unit. The memory includes a projection buffer and a shadow buffer. An incoming stream of pixel information scanned from the MEMS mirror is written to the shadow buffer. The incoming stream of pixel information is forwarded to the projection buffer. The projection buffer forwards the incoming stream of pixel information to the projection unit. The projection unit projects the incoming stream of pixel information based on the Lissajous pattern through a mirror projector trajectory. The shadow buffer and the projection buffer operate at different frequencies.

Abstract: The present invention provides a flexible battery, including an electrochemical cell layer and a wrapping layer that wraps the electrochemical cell layer. The flexible battery further includes an energy absorbing layer. The energy absorbing layer is located between the wrapping layer and upper and lower surfaces, which are opposite to each other, of the electrochemical cell layer. The energy absorbing layer includes a plurality of supporting parts that protrude outward from the upper or lower surface of the electrochemical cell layer. The plurality of supporting parts are mainly made of a foam material or rubber. For the energy absorbing layer, a lower-modulus buffering layer or an empty part may be further disposed between the electrochemical cell layer and the wrapping layer, to complement a wavy surface of the supporting part to form a flat surface.

Abstract: The present disclosure provides a Lissajous dual-axial scan component (100) that includes an outer frame (102), a first pair of supports (104A-B), a second pair of supports (106A-B), an inner frame (108), a mirror (110), a sensing arrangement (112), a controller (114) and a memory (116). The memory (116) stores multiple tuples each including a first-axial bias frequency value, a second-axial bias frequency value, and a phase difference between actual driving frequencies (i.e. a first-axial bias frequency and a second-axial bias frequency) of the mirror (110). The controller (114) is coupled to the sensing arrangement (112) to receive signals indicative of current resonant frequencies of the mirror (110) and configured to select one of the tuples from the memory (116) based on the signals received from the sensing arrangement (112) and set the applied bias frequencies, and their phase difference, according to the selected tuple.

Abstract: A deflection device for Lissajous scanning is provided. The deflection device includes a frame and a mirror. The mirror is movably arranged in a recess in the frame by means of a suspension mount including one or more springs. The mirror may be configured to swing back and forth about each of two or three axes with a respective eigenfrequency for reflecting incoming light at different angles to form a two-dimensional Lissajous pattern. The deflection device may include a driving device configured to excite swing motion of the mirror about each of the two or three axes at or near the respective eigenfrequency. Each of the one or more springs has a shape of a path segment along a circumference of the mirror together covering more than 360 degrees. An arrangement of the one or more springs provides a compact suspension for the mirror and larger tilt angles.
