Abstract: A voice-activated light system that includes a microphone for receiving one or more voice commands (which may be referred to as a “voice microphone”), one or more light sources (such as LEDs) coupled to a controller and a light driver. The light driver is for driving the light sources and the controller is for detecting a voice command in order to control the mode of operation of the one or more light sources. The controller can have multiple control commands each for selecting a different mode of operation of the light source(s). The modes can be controlled by a common voice input term followed by a second voice command corresponding to a mode of operation of the light source. The system may include a second microphone which may be referred to herein as a “music microphone”. The commands can include “light show,” “slow pulse,” “steady on,” “blinking,” or “off”.

Abstract: A power supply module and a power supply judgment method thereof are provided. A power supply circuit supplies power to an electronic device coupled to the power supply module. A plugging detection circuit detects the connection state of the electronic device. A judgment circuit switches the electronic device to connect to a first signal channel or a second signal channel in response to whether the electronic device provides device information of the electronic device within a preset time since the electronic device is coupled to the power supply module. The power supply judgment method of the invention automatically sets signal channel configurations corresponding to different external devices, thereby greatly improving the convenience of use.

Abstract: The present disclosure relates to immunogenic compositions comprising a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen, and a toll-like receptor 9 (TLR9) agonist, such as an oligonucleotide comprising an unmethylated cytidine-phospho-guanosine (CpG) motif. The immunogenic compositions are suitable for stimulating an immune response against a SARS-CoV-2 in an individual in need thereof.

Abstract: A display arrangement includes a base, a decorative shell having a front cover and a back cover, an elongated central post that is rotatably coupled to the decorative shell and fixedly coupled to the base, a light source disposed on the elongated central post and within the shell, such that the light is visible though at least one opening in the shell, a stem coupled to the shell and coupled to the elongated central post, the stem having a magnet on one end, and a coil configured to receive energy from a power source to cause an arcing motion of the magnet, the stem, and thereby the decorative shell. The display arrangement can include a second shell disposed horizontally above the decorative shell and coupled to the decorative shell, and can also include a third shell disposed horizontally below the decorative shell, and that is coupled to the decorative shell.

Abstract: A projection apparatus includes a light valve, a lens module, a distance measuring module, a lens position detection module and a processor. The light valve forms an image beam. The lens module projects the image beam onto a display surface. The distance measuring module detects a distance between the lens module and the display surface to obtain a first distance value. The lens position detection module detects a position of the lens module to obtain a second distance value. The processor receives the first distance value from the distance measuring module, receives the second distance value from the lens position detection module and obtains an effective focus range according to the second distance value.

Abstract: A projection system and a keystone correction method are provided. The projection system includes: a projector projecting an image to a projection zone; an image capturing device capturing a captured image including the projection zone; and a processor. The processor divides the captured image into multiple focusing zones, and controls a stepper motor to shift focusing on the focusing zones at edges to obtain a step of the stepper motor and a distance for each of the focusing zones with a maximum clarity value. The distance is a projection distance between a lens module and the focusing zone. The processor calculates an included angle between the direction of a light axis of the projector and the projection zone according to the distances of the focusing zones at the edges, and performs a warping operation on a projection image according to the included angle.
