A dispensing device (1) with multi-arm tubing assembly (10) connected to a single source pumping means (12) draws and mixes multiple fluids from plurality of flexible walled sealed supply containers (50a,b) then expels the mixture (60) through nozzle (58) to a target surface (62). Dispensing device (1) provides a closed system whereby no venting occurs, rather supply containers (50a,b) contract in size equal to the volume of fluid expelled. Unstable fluids thus remain protected from exposure to outside air. Additionally, a new use of a repressurization device is disclosed for maintaining the potency of unstable fluids like hydrogen peroxide and a kit is provided which allows user to choose from various components and accessories as needed to suit their multi-chemical dispensing needs.

When the conductive portion and the opening portion form a mesh pattern, the moire preventing part may be formed approximately at the center of the opening portion, and may be formed on an intersection of the mesh pattern.

The invention relates to a light management device in a monitoring system, in particular to a stroboscopic light management device which comprises a synchronous signal unit, a frequency multiplication unit and a trigger control unit, wherein, the frequency multiplication unit receives a standard reference signal sent from the synchronous signal unit and outputs a frequency multiplication signal. When receiving a trigger signal, the trigger control unit outputs a control signal with a given pulse width according to the obtained frequency multiplication signal. By adopting a synchronization technique, the device of the invention ensures stroboscopic lights emitted by a light source and a shutter of a camera to be synchronous, so that all luminous power is exerted during the action period of the shutter of the camera, while during the period of closing the shutter of the camera, no lights is emitted or the lowest brightness is kept. In addition, frequency of a strobe is increased to 100Hz, therefore, no influence is imposed on human eyes, and the illumination intensity of backlighting parts does not need to be considered when the camera shoots backlighting pictures. The light supplementation of the backlighting parts is realized by an impulse LED lamp and the shooting of backlighting objects moving at high speed can be realized.

The invention provides a detection system and detection method for a camera module group, and a method for providing a uniform light source for the camera module group. The detection system that is suitable for carrying out imaging performance detection on a camera module group consists of a light source and an integrating sphere having an output port; the light emitted by the light source enters the integrating sphere, so that a uniform light beam is obtained at the output port; and the output port is suitable for setting the camera module group, so that the light beam can enter the camera module group for imaging.

The invention relates to a hurdle lamp lens comprising a back end surface, a front end surface opposite to the back end surface and a side surface arranged between the front end surface and the back end surface, wherein the back end surface is provided with an accommodating groove, and the inner wall of the accommodating groove is an incident surface of the hurdle lamp lens; a first light emitting surface of the hurdle lamp lens is formed on the front end surface; the side surface comprises a first side surface near the top side of the hurdle lamp lens and a second side surface near the bottom side of the hurdle lamp lens, the first side surface is a first light reflecting surface of the hurdle lamp lens, and the second side surface comprises a second light emitting surface near the back end surface and a second light reflecting surface arranged between the second light emitting surface and the front end surface. The hurdle lamp lens foundationally enables rays emitted by a light source of a hurdle lamp to be used for irradiating a road surface and a hurdle, thus, rays emitted by the light source of the hurdle lamp can be efficiently utilized. The invention also relates to a hurdle lamp with the hurdle lamp lens.

A developing unit of the present invention includes a case which accommodates toner containing pigment, a developing roller, a supply roller formed of an elastic member arranged to be pressed against a surface of the developing roller in such a manner as to supply toner to the surface of the developing roller. The toner contains a first and second additive having a specific covering ratio to the surface matrices in the toner.

The invention discloses a vehicle control method and system based on a reversible lane of a car yard. The vehicle control system comprises a direction triggering component, a license plate recognition triggering component, a license plate capturing component, a display and control component and a monitoring platform. The direction triggering component is used for generating a first continuous triggering signal when detecting entry of a vehicle; the license plate recognition triggering component is used for generating a second transient triggering signal when sensing passing of the vehicle; the monitoring platform is used for judging the direction of travel of the vehicle on the basis of the received first triggering signal and second triggering signal, controlling the license plate capturing component to capture a vehicle head image based on the second triggering signal, obtaining a license plate number from the vehicle head image through analysis, and sending corresponding vehicle information to the display and control component; the license plate capturing component is used for capturing the vehicle head image comprising the license plate number; and the display and control component is used for displaying the corresponding vehicle information. The vehicle control method and system are advantageous in that, travel direction of the vehicle can be recognized, vehicle management is facilitated, and vehicle passing efficiency is improved.

The present invention provides a camera system including: an imaging unit which has an image-taking optical system and an image pickup device; and a main unit which receives image signals from the imaging unit and performs signal processing. The imaging unit includes an identification section for identifying the main unit. When the imaging unit is attached to the main unit and the power is supplied from the main unit to the imaging unit, the imaging unit issues to the main unit a request for the transmission of the identification code. In response to the request, the main unit sends the identification code to the imaging unit. The identification section of the imaging unit identifies the main unit based on the received identification code.

The embodiment of the invention discloses a video generation method and device. One specific embodiment of the method comprises the following steps: sending a video request to at least one second terminal; in response to determining that the first terminal is matched with the at least one second terminal, shooting a video, and receiving a to-be-synthesized video transmitted by the at least one second terminal, the to-be-synthesized video meeting the shooting parameter; and synthesizing the shot video with at least one to-be-synthesized video to obtain a panoramic video. According to the embodiment of the invention, the video shot by each terminal can be synthesized to realize the synthesis of the videos of multiple view field angles, so that the panoramic video with more comprehensive viewfield angles can be produced. Moreover, the first terminal and the second terminal are matched, so that unknown equipment is prevented from being added into the shooting and synthesis process of thevideo, and the information security of the equipment and the smooth video synthesis are ensured.

The invention application discloses an intelligent monitoring method, and relates to the field of the monitoring. The method comprises the following steps: step one, a monitor camera sends a shot monitoring image to a correspondingly connected display and server; step two, a face recognition module in the server recognizes a face image from the monitoring image; step three, when the face recognition module cannot recognize the face image from the monitoring image, the server defines the monitoring image which starts from this time until the monitored personnel leaves as the abnormal event image, the server sends the abnormal event image to a database to save; and step four, the server controls a prompt lamp corresponding to the display form displaying the abnormal event image to be lightened. The monitoring method disclosed by the application can remind the user when the monitor camera does not shoot the face of the monitored personnel.
