Abstract: A task dispatching method for EPD tag devices includes receiving a task command; the server system forwarding the task command to a target router to which the target EPD tag device is connected; the target router checking whether the target EPD tag device is currently connected thereto; when it is determined that the target EPD tag device is not currently connected to the target router, the target router notifying the server system that the target EPD tag device is offline; in response to receiving an online notification indicating that the target EPD tag device is connected to another router, the server system updating a connection list accordingly, and forwarding the task command to an updated target router; and when it is determined that the target EPD tag device is currently connected to the target router, the target router delivering the task command to the target EPD tag device.

Abstract: A sound wave receiving device including: an aerial vehicle having a rotor blade; an array sensor mounted on the aerial vehicle and including a plurality of microphones; a first shield installed between the rotor blade and the array sensor, the first shield being configured to suppress an influence of sound wave noise generated by the rotor blade on a sound wave received by the array sensor; and a second shield provided along a peripheral portion of the array sensor, the second shield being configured to suppress reception by the array sensor of external sound from outside a sound wave reception range set in advance for the sound wave.

Abstract: An abundance of specific species of phytoplankton in a phytoplankton group in which a plurality of kinds coexists is calculated in a simple manner. Based on a reference sample intensity ratio r0, a reference sample total fluorescence intensity I0, and an existing quantity K0 of specific species of phytoplankton, an intensity ratio rd of other species of plankton is calculated. An analysis sample that is expected to have similarity with the reference sample is irradiated with the excitation light, an intensity of fluorescence emitted from the analysis sample is measured in each of wavelength bands A and B, and an intensity ratio r is calculated. A total fluorescence intensity I is measured, and an existing quantity K of the specific species of the phytoplankton is calculated based on the intensity ratio rd of other species of plankton, the intensity ratio r, and the total fluorescence intensity I.

Abstract: A device for determining sound source direction includes an array sensor including a plurality of microphones that measures a sound wave, and a processor for calculating a sound pressure in each direction based on sound pressure information of the sound wave obtained by the array sensor and for determining a direction in which the sound pressure is maximum as a direction of sound wave arrival. The plurality of microphones is provided at vertices of two or more concyclic polygons that are on a same plane and that have a same center and are arranged so as to be non-rotationally symmetric as a whole array sensor.

Abstract: A circuit board heat dissipation system includes circuit board unit that includes a motherboard and a daughterboard, a base seat, and a fastening unit that includes a plurality of first and second fastening components. Each first fastening component extends through the daughterboard and is engaged with the base seat. Each second fastening component includes a long fastener that extends through the base seat and the daughterboard and that is engaged with the motherboard, and a flat washer and a resilient member that are sleeved on the long fastener. The resilient member is disposed between a head portion of the long fastener and the flat washer for biasing the base seat and the daughterboard against the motherboard.

Abstract: A mobile medication workstation comprises a platform module and a battery module. The battery module is disposed on the platform module. The platform module has an article placing platform and an accommodating portion. The platform has an article containing area. The accommodating portion is used to accommodate a storage box. The mobile medication workstation comprises a first wireless charging module and a second wireless charging module. The first wireless charging module is electrically connected to the battery module and is close to the placing goods area. The second wireless charging module is electrically connected to the battery module and is close to the storage box. When a handheld device is placed in the article containing area, the first wireless charging module supplies power to the handheld device, and when the storage box is placed in the accommodating portion, the second wireless charging module supplies power to the storage box.

Abstract: An improved structure of a interface card panel of a compact PCI system is disclosed. Wherein the panel of an interface card is assembled by welding an inner layered plate and an outer layered plate. The thickness of each layered plate is only half of the standard plate. The through holes of the inner layered plate have a radius only sufficient for receiving the screw rods of the fixing studs on the two ends of a D type connector, while the through holes for the outer layered plate have a radius sufficient for receiving the whole fixing studs, so that the fixing studs will completely pass through the outer layered plate, while the bodies thereof press the rim of the holes of the inner layered plate. Thus, other than the fixing points on the buckling bodies on the two ends thereof. By the fixing studs of the D type connector, a large fixing force is formed on the middle of the panel, and meanwhile, the strength of the panel is improved.

Abstract: A load cell comprises a column elastic body 11; a circle bore 12 formed on a center portion of a first end surface 11a of the column elastic body 11, a bottom wall of which constitutes a load acting surface 13; an annular concave groove 15 formed on a second surface 11b of the column elastic body 11 being coaxial with the circle bore 12, a bottom portion of which constitutes a strain occurrence portion 18, a outer portion of which constitutes a fixing portion 16 of thick cylinder configuration; and Strain gages stuck on the strain occurrence portion. A distance "y" from the load acting surface 13 to a surface of the strain occurrence portion 18 is 0.2 to 2 times shortest distance "e" from a center axis of the column elastic body to the strain gages.

Abstract: A communication system and method that reduces the number of converters required for communication between a personal computer and a plurality of instruments includes a master data transmission converter coupled to the personal computer and adapted to communicate with the personal computer and a plurality of branch data transmission converters. Each of the branch data converters being coupled to the master data transmission converter through an RS485 interface and one of the instruments through an RS232 interface. Each of the branch data transmission converters having a unique individual identity address code such that only one communication path is built between the master data transmission converter and a branch data transmission converter that has been addressed by an information signal from the personal computer via the master data transmission converter.

Abstract: A strip detecting apparatus comprising a plurality of measurement rings axially arranged around an outer circumference of a fixed shaft, characterized by a floating inner ring fitted to the fixed shaft via a load cell and an outer ring externally fitted to an outer circumference of the floating inner ring so as to rotate freely. A cell portion containing a strain gauge sealed with an inert gas in a load cell is arranged with a cooling means to detect a shape of a high-temperature strip.
