Abstract:
A system for classifying tiny insects includes a cultivation tank, a detecting container, a detector, a gathering device, and a control unit. The cultivation tank is connected to the detecting container, so that the hatched tiny insects can enter the detecting area of the detecting container from the cultivation tank. The detector is used for detecting the characteristics of the tiny insects in the detecting area, and then the control unit controls the switching unit of the gathering device to switch the gathering containers for gathering the tiny insects according to the detecting results. The system of the present invention is capable of automatically classifying the tiny insects and then gathering them to different gathering containers according to their characteristics, so as to decrease the man power and time necessary for factitious classification.
Abstract:
A power switching device including a rectifier circuit and a control circuit is provided. A first terminal of the rectifier circuit receives an external voltage source and a second terminal of the rectifier circuit is electrically connected to a node. The control circuit is electrically connected between the node and a battery. Furthermore, during a power supply mode, the control circuit provides a power supply path, so that the battery provides a battery current to the node. Besides, the control circuit detects the battery current and determines whether or not to switch to a normal mode from the power supply mode according to the detection result.
Abstract:
A trigger device is mounted on a rivet gun. The rivet gun has a barrel, a handle and a pneumatic cylinder. The trigger device has an inlet channel defined in the handle, an outlet hole defined through the handle and communicating with the barrel, a valve-driving channel defined in the handle and communicating with the pneumatic cylinder, a space defined in the handle and communicating with the inlet channel, outlet channel and valve-driving channel. A trigger member is mounted on the handle. A two-step pressing assembly is mounted in the space and may be activated to control the rivet gun to eject a core pin of a used rivet or rivet pieces with an unused rivet. High-pressure air from an air source connected to the rivet gun is output only during the ejection operation of the rivet gun to prevent unnecessary air consumption and noise.
Abstract:
A multimedia data sharing system and method for a MOST network is disclosed. The system provides a service management module, a data link control module, and a protocol conversion module. The service management module provides state analysis and management for all services of the multimedia data sharing system and records analyzed service states and configuration results in a service management list. The data link control module performs a control and management process for system data streams based on information stored in the service management list. The protocol conversion module retrieves data from a channel register, based on the information stored in the service management list, to perform a MOST link management operation and implements a packaged or an unpackaged operation to data packets for access of the MOST network.
Abstract:
An integrated broadband antenna device with wide band function is disclosed. The antenna device comprises a ground plate, a feeding wire, a first metal radiator, a second metal radiator, a ground metal radiator and a parasitic metal radiator. The first metal radiator is connected with the positive ends of signals of the feeding wire for transmitting electric signals and producing a high frequency mode. The first metal radiator is coupled to and energizes the second metal radiator and the parasitic metal radiator, and then the two metal radiator producing a low frequency mode and a second high frequency mode along with the ground metal radiator obtains a wider bandwidth. The broadband antenna device integrating various kinds of antennas is able to have a enough bandwidth to meet the requirements of AMPS (824˜894 MHz), GSM (880˜960 MHz), GPS (1575 MHz), DCS (1710˜1880 MHz), PCS (1850˜1990 MHz), UMTS (1920˜2170 MHz) and Wi-Fi (2400˜2500 MHz).
Abstract:
A multi-frequency antenna with dual loops is provided. The antenna includes a T-shaped radiator having a first arm and a second arm of unequal lengths as a main body, and two grounded L-shaped radiators, so as to form dual loops. Thus, the antenna can operate in a high-frequency operation mode and a low-frequency operation mode. With the dual loops, the antenna obtains enough bandwidths at high frequency, and also meets the requirements of low frequency. More specific, the antenna meets the requirements of high-frequency systems, such as DCS/PCS/UMTS and those of low-frequency systems, such as AMPS/GSM.
Abstract:
An automatic suction and repelling device for rivet gun, which comprises a body and a handle, and the intake passages thereof are in communication each other; the rear center of the body is furnished with a regulation ring and a used-nail cylinder; the regulation ring can be adjusted to move by means of screwing so as to adjust the volume of pressure air to enter the body, and to adjust the vacuum suction force in the used-nail pipe; during rivet-pulling work, the rivet gun can automatically suck in, and can suck a used nail into the used-nail cylinder upon the rivet-pulling work done.
Abstract:
A structure of rivet nut gun having a body, a handle and a pressure cylinder. The top of the handle is furnished with a mounting base having a through cylindrical hole. The lower end of the handle is furnished with a base surface for mounting the fastening disk. The body has a connector mounted with a connecting rod to penetrate through the cylindrical hole of the handle. The fastening disk is fastened to one end of the connecting rod by a nut. The fastening disk is connected with two symmetrical screw rods, which penetrate through the piston and the pressure cylinder, and are fastened to the bottom of the pressure cylinder by two nuts respectively so as to have the piston cylinder fastened in place and to prevent the pressure cylinder from deformation during the rivet nut gun operating.
Abstract:
A scarifying and deburring tool includes a body, a handle mounted to the body, and a scarifying brush. The body has a fixing hole in an outer periphery thereof. A deburring scraper and a fixing block are mounted inside the body. The fixing block has a fixing hole in an outer periphery thereof.
