A staple refill which can be stored in a refill storing section in such a manner that the leading one of the sheet-like joined staples wound in roll form is on the upper side and which is adapted to lessen the load on a feeding mechanism for feeding the leading one of the sheet of joined staples in a stapler main body. The staple refill is removably attached to a cartridge installed in a stapler main body. A refill includes a storing section for storing a sheet of joined staples wound in roll form, a discharge port for discharging the sheet of joined staples, and a lead-out passage for leading out the leading part of the sheet of joined staples into the discharge port. The lead-out passage is upwardly bent from the discharge port toward the interior of the storing section, so that the leading part positioned on the upper side of the sheet of joined staples is lead out to the discharge port. The lead-out passage is provided with a retrograde motion preventive member which prevents movement of the sheet of joined staples to the storing section.

The invention discloses an oriented monitoring system with a radio-frequency signal identification function. The oriented monitoring system comprises oriented passage doors, an Ethernet module, a server module, a management module and a database module. Each of the oriented passage doors is provided with an RFID (radio-frequency identification device) and RFID antennae, and radio frequency identification signals emitted by the RFID antennae cover any sides of the oriented passage doors and are used for identifying EPCs (electronic product codes) of RFID labels when people and articles with the RFID labels pass through the oriented passage doors. The Ethernet module is used for transmitting the identified EPCs of the RFID labels to the server module. The server module is used for performing data analysis and data processing on the received EPCs, judging moving directions of the people and the articles, detecting retrograde motions, hover and retention of the people and the articles and emitting sound-light alarm control signals. The management module is used for setting the moving directions of the people and the articles allowed by the oriented passage doors and displaying moving tracks of the people and the articles in real time. The data module is used for storing the moving directions of the people and the articles allowed by the oriented passage doors and moving track data of the people and the articles passing through the oriented passage doors.

The invention belongs to the technical field of intelligent transportation, and provides a streaming monitoring analysis pre-warming system and method specific to vehicles based on fog calculation. The streaming monitoring analysis pre-warming method comprises the steps that state data of all vehicles is collected specific to the vehicles in travelling and uploaded to a distributed message queue module on fog equipment, according to the real-time data, real-time traffic information and driver behavior models are obtained by using a big data analysis method, the situations that present driver behaviors are abnormal and whether retrograde motion of the vehicles occurs or not are discovered in time, and the traffic information and the driver behavior models are stored in a local storage module and meanwhile transmitted to a history data storage module in a cloud calculation center; in addition, the vehicle position and the driver behaviors of future period of time are forecasted, and advanced warning of traffic accidents possibly occur in the future is facilitated. According to the streaming monitoring analysis pre-warming system and method specific to the vehicles based on the fog calculation, the defects that time delay is long, load of calculation center is heavy, network flow is large and network congestion is prone to occurring of a traditional vehicle safety monitoring system are overcome, and the safety of road traffic is improved.

Methods and apparatus are provided for forming an initiation flaw (111) in the surface (114) of a glass sheet or glass ribbon (13). The initiation flaw (111) is used in connection with a laser light beam (121) and a cooling area produced by a cooling nozzle (119) to from a score line (115) in the surface (114) of the sheet or ribbon (13). The initiation flaw (111) is formed by a mechanical scoring head (20) which is carried by moving carriage (14) and which undergoes retrograde motion (19) relative to the carriage (14) so as to increase the time available for forming the initiation flaw (111).

The invention relates to a one-way speed bump. The one-way speed bump is characterized in that the one-way speed bump for controlling a vehicle to perform one-way driving deceleration consists of a speed bump (2), a spring (3), a front fixed plate (4), a connecting shaft (5), a front fixing nail (6) and a rear fixing nail (7), the spring (3) is arranged in the arc-shaped rest front part, with a raised middle, of the speed bump (2) so that the bottom surface of the arc-shaped rest front part, with the raised middle, of the speed bump (2) leaves the ground (1), warps up and is separated from a triangle part under the condition that the raised arc front part is not pressed by external force, and a ridge for preventing the vehicle from making retrograde motion is formed; the front fixed plate (4) is connected with the arc-shaped front part, with the raised middle, of the speed bump (2) by the connecting shaft (5). The one-way speed bump creates an open innovation concept, can be widely applied to one-way streets and solve the problem of the retrograde motion of the vehicle in a one-way street due to the fact that the design of the traditional speed bump is not quite suitable for the one-way street.

The present invention discloses a vehicle abnormal behavior detection and tracking method based on DSRC. The method comprises: a road side personal communication unit is configured to obtain information from a vehicle device, a roadbed computer is configured to calculate the information to obtain the speed of the vehicle, the traffic flow of the road and the traffic density, perform speed abnormity determination through adoption of a threshold value comparison method by a abnormity detection module and determine the vehicle illegal parking and retrograde motion through a design algorithm. Through adoption of a DSRC communication technology between vehicles and roads, the vehicle abnormal behavior detection and tracking method based on DSRC provides a calculation method of microcosmic traffic volume, vehicle speed, macroscopic traffic volume, traffic flow and traffic density so as to solve the problem that the vehicle abnormal behavior is identified and tracked with low cost and accuracy in the car networking environment.

A method for determining the semi-major axis of the equatorial orbit of a sub-satellite point regular return, comprising: 1) selecting the forward and retrograde motion of the equatorial circular orbit; 2) selecting the return times of the satellite in a single day, and calculating the sub-satellite point return cycle hours N according to the formula; 3 ) Calculate the return period of the satellite in the inertial space according to the number of hours N of the return period of the sub-satellite point; 4) Calculate the semi-major axis corresponding to the prograde and retrograde equatorial return orbits according to the return period of the inertial space. The invention proposes a concept of an equatorial orbit capable of realizing sub-satellite point return at multiple specific times each day, and provides a method for determining the semi-major axis of the equatorial orbit. Equatorial satellites based on this orbit can realize hour-level revisiting of any region in the middle and low latitudes by a single satellite, and realize regular revisiting of the region multiple times a day.
