Disclosed herein is a housing for containing a laser and lens for use in a laser light projection display, and a lighting device incorporating the laser within the housing and other light sources, such as light-emitting diodes (LEDs). The laser and lens are secured within a housing and maintain a spaced distance using a spacer. The lighting device uses the laser in combination with LEDs arrayed around the laser to provide a dual source light.

A laser mount for fixedly coupling a laser pointer includes: a first layer; a second layer including a first end and a second end, a connection between the first layer and the first end forming a spring-tensioned hinge, such that deflection of the second end about the connection imparts a spring tension to the second layer, and the second end being spaced apart from the first layer; a first adjustment screw configured to vertically couple the first layer and the second end and to adjust a vertical spring tension between the first layer and the second layer; and a second adjustment screw configured to horizontally couple the first layer and the second end and to adjust a horizontal spring tension between the first layer and the second layer.

A head-mounted device (HMD) is structured to include at least one computer vision camera that omits an IR light filter. Consequently, this computer vision's sensor is able to detect IR light, including IR laser light, in the environment. The HMD is configured to generate an image of the environment using the computer vision camera. This image is then fed as input into a machine learning (ML) algorithm that identifies IR laser light, which is detected by the sensor and which is recorded in the image. The HMD then visually displays a notification comprising information corresponding to the detected IR laser light.

A meta projector includes an edge emitting device configured to emit light through a side surface thereof, a meta-structure layer spaced apart from the upper surface of the edge emitting device that includes a plurality of nanostructures having a sub-wavelength shape dimension smaller than a wavelength of the light emitted from the edge emitting device, and a path changing member configured to change a path of the light emitted from the edge emitting device so as to direct the path toward the meta-structure layer. The meta projector may thus be configured to emit a light pattern of structured light, based on directing the light emitted from the edge emitting device through the meta-structure layer, while having a relatively compact device size.

A system and method for enhancing laser contrast on a remote target utilizing an image processor and a laser power controller is provided. An image processor in an imaging device manipulates a laser power controller in a laser system so that a laser beam emitted from a laser system is ultimately synchronized with the imaging device. Firstly, the original laser signal is shifted one time frame relative to the plurality of time frames to create a shifted laser signal. Secondly, the shifted laser signal is subtracted from the original laser signal. Thirdly, the subtracted laser signal is magnified by a frequency band pass filter. The filtered laser signal is added to the original signal to become the finalized laser signal which has better contrast than the original signal.

A disclosed medical observation system includes a capturing unit operable to capture an image of an observation target; and a light projection unit operable to project light on the observation target, outside a capturing area that is captured by the capturing unit and in a periphery of the capturing area, the light enabling recognition of a capturing state of the capturing unit.

A type-c and USB two-in-one interface wireless radio frequency receiver, including a USB interface, a USB portion, a Type-c portion, an upper cover, a lower cover, a handle, and a connecting magnet. The USB portion is connected to the Type-c portion and placed on the lower cover. The USB interface and the type-c interface are fixed in the same storage device, but they are only physically fixed together, and the internal data is stored separately and is not mixed. When exporting data, the corresponding USB or type-c interface will be used, so that no matter which interface is used, this two-in-one receiver will meet the needs. A handle with a rotary design is further provided to protect the Type-c portion from damage. The upper side of the handle is fixed to a fixing rope via the fixing hole, so as to tie the device and facilitate to carry it around.
