An undercoat rake adapted for use in grooming a furred animal. The undercoat rake includes grooming teeth comprising at least two different types of grooming teeth, each having a base portion, a tip portion, and a shoulder between the base portion and the tip portion. First teeth of the two different types of grooming teeth may have a tip portion that is greater in length than the corresponding tip portion of second teeth to create a variable depth grooming profile. The disclosed structure advantageously removes undercoat fur of a furred animal that has been shed or is soon to be shed. The variable depth grooming profile has been found to be highly effective to rapidly and efficiently thin the undercoat of a furred animal.

An image processing method generates a halftone-dot image by forming a halftone dot, which is represented by a set of one or plural output dots and corresponds to an intensity of an input image signal, while making a part of the dots constituting the halftone dot to be an actual non-output dot so as to reduce an amount of a coloring material of the halftone-dot portion. When the intensity of the image signal exceeds a predetermined value and is in a predetermined range, while maintaining contour dots, which are output dots contribute to formation of a contour of the halftone dot, to be the output dot, the image processing method makes a part of dots inside the contour dots to be the actual non-output dot.

The invention discloses an optical fingerprint recognition device and a preparation method thereof, comprising a transparent substrate, a luminous light source and an optical sensor, the transparent substrate is provided with a finger touch area; the luminous light source is located in all or part of the area around the finger touch area , and is located below the transparent substrate; the optical sensor is arranged below the finger touch area, the light source is a plane light source, the light source is also provided with a light-shielding structure for limiting the angle of light emitted by it, and the light emitted by the light source After being shaded by the light-shielding structure, the part enters the finger touch area. The optical fingerprint identification device provided by the present invention adopts a plane light source, which can effectively thin the device, and at the same time, a light-shielding structure is arranged on the plane light source, and part of the light emitted by the plane light source will be blocked by the light-shielding structure, thereby avoiding light leakage interference of some light rays, The signal-to-noise ratio between the fingerprint signal and the light source signal is greatly reduced, and the ability to identify the fingerprint signal is improved.

The invention relates to a physical dryer for preparing a composite aerogel self-thermal-insulation template. The physical dryer comprises a first drying part and a second drying part, wherein the second drying part is configured to be a hollow outer shell to form a containing space capable of containing the composite aerogel self-thermal-insulation template, and the composite aerogel self-thermal-insulation template can be supported; and a negative pressure space in a negative pressure state in which the air pressure is smaller than the standard atmospheric pressure is formed in the first side, which is approximately perpendicular to the ground direction, of the composite aerogel self-thermal-insulation template, gas in the atmospheric environment can enter the containing space based on the negative pressure state, moreover, gas located on the second side, opposite to the first side, of the composite aerogel self-thermal-insulation template can move along the second side in the direction pointing to the first side on the basis of the negative pressure state, so that the gas positioned on the second side can enter the composite aerogel self-thermal-insulation template from the second side and is discharged out of the composite aerogel self-thermal-insulation template from the first side, and the gas penetrating the composite aerogel self-thermal-insulation template can be discharged out of the containing space through the negative pressure space.

A backlight module for a liquid crystal display (LCD) device includes a bottom plate, a plurality light sources, a light-premixing unit, and a light-mixing unit. The light sources are mounted on the bottom frame. The light-premixing unit is located above the bottom frame. The light-premixing unit includes a first diffuser. The light-mixing unit is located at a distance above the light-premixing unit. The light-mixing unit includes a second diffuser. The backlight module can effectively reduce the thickness of and meet the slim-line requirement of the LCD.

The invention belongs to the technical field of precision grinding, and particularly relates to a particle composition for grinding. The composition in the form of a solid columnar particle and acts on the surface of a to-be-machined workpiece in the thinning and polishing process of the to-be-machined workpiece to achieve grinding effect; so on the basis that the surface roughness of the workpiece is accurately controlled, grinding efficiency is improved, manpower and material resource input is saved, and the problems of high cost, production pollution discharge and the like are solved. In addition, directed at the requirements of rough thinning, fine thinning, different products, different product roughness and the like, the particle composition can accurately meet diversified requirements of products by using diamonds with different particle sizes and concentrations.

The invention discloses an optical sensing module, which comprises a light conducting element, a light source, a light blocking element, a plurality of optical sensors and optical elements.The light conducting element has a plane of light incidence and a plane of emitting light and the light source provides light.The light blocking element is arranged on a portion of the plane of emitting light and the plurality of optical sensors are arranged on the light blocking element.The optical elements are arranged above the plane of emitting light.The optical sensors and the light blocking element are arranged between the optical elements and the light conducting element.The optical elements have touch surfaces.Light discharged out of the plane of emitting light passes through the optical elements.When an object touches the touch surface, the light is reflected and is received by the optical sensors.
