CPC Class H04N

A method for generating an infrared (IR) beam for illuminating a scene to be imaged comprises providing at least two IR emitters, including a first IR emitter operable to emit a wide beam component of the IR beam, and a second IR emitter operable to emit a narrow beam component of the IR beam, wherein the wide beam component has a linear profile that has a lower standard deviation than a linear profile of the narrow beam component. The method also comprises selecting a desired linear profile for the IR beam, and selecting a power ratio of power directed to the first IR emitter and power directed to the second IR emitter that produces the IR beam with the desired linear profile when the narrow beam component and wide beam component are combined.

A camera system including an objective, an objective holder carrying the objective, an image sensor and a printed circuit board. The printed circuit board and the image sensor are connected to one another in an electronically conductive manner, and the image sensor and the objective are arranged such that an image is n focus on the image sensor. The printed circuit board has a circuit layer made of an electrically insulating material and a printed circuit board substrate, wherein the printed circuit board substrate is manufactured from a material with a coefficient of thermal expansion aL which deviates by no more than 30% from the coefficient of thermal expansion of a material from which the objective holder is manufactured.

A display device includes a curved display module which includes a signal receiver receiving an image signal from an outside source, an image display part displaying an image corresponding to the image signal and being curved, and a frame surrounding at least a portion of an edge of the image display part and a stand which includes a signal transmitter transmitting the image signal and a coupling part in which a curved groove is defined where a portion of the curved display module is accommodated in the groove.

A protective cover assembly includes a protective cover having a cover plate body with opposite inner and outer cover plate surfaces, and a through hole extending through the inner and outer cover plate surfaces and defined by a hole-defining wall having a stepped surface. An attachment member is removably embedded in the through hole, and includes a base plate, an outer flange extending outwardly from and surrounding the base plate, a main hole extending through the base plate, and an annular protrusion protruding from an inner peripheral edge of the main hole and extending out of the through hole. The outer flange has a first flange surface flush with a base plate surface of the base plate, and a second flange surface abutting against the stepped surface.
