Abstract:
A wireless transmission device, arranged inside a display object or connected with the display object, includes a power supply interface, an initialization setting button, a wireless transmission unit, a processing unit, and a storage unit. The input end of the power supply interface is connected with the power supply end of the display object, the output end of the power supply interface is connected with the wireless transmission unit and the processing unit respectively, and the initialization setting button and the storage unit are connected with the processing unit respectively. A unique identification assigned to the display object is stored in the storage unit. Initialization setting of the wireless transmission device is implemented by pressing the initialization setting button, and the processing unit transmits out the identification, orientation, and/or predetermined viewable angle of the display object constantly or regularly via the wireless transmission unit.
Abstract:
A light source apparatus for fluorescence photography of biomolecule sample gels is disclosed. The light source apparatus comprises a housing, a transparent plate disposed in a light transmission zone at the top of the housing, and at least one LED array disposed in the housing out of the range of the light transmission zone. The LED array irradiates obliquely to the light transmission zone for preventing the light spots from interfering in the observation. Each of LED array may comprises different colors of LEDs for different biomolecule samples.
Abstract:
Provided herein is a device for quantitative analysis of a micro-volume solution. The device comprises a base portion provided with a light-emitting fiber, a movable arm provided with a light-receiving fiber, and at least one positioning block disposed between the movable arm and the base portion so that an optical path with a constant length is formed between the light-emitting fiber and the light-receiving fiber when the positioning block is clamped by the movable arm and the base portion. The solution concentration related to the absorbance with respect to the standard optical path length may be evaluated based on the built-in database and the optical intensity of light having passed through the solution as detected by a light sensor.
Abstract:
A system and method for controlling an AC motor drive includes a control system programmed with an energy algorithm configured to optimize operation of the motor drive. Specifically, the control system input an initial voltage-frequency command to the AC motor drive based on an initial voltage/frequency (V/Hz) curve, receives a real-time output of the AC motor drive generated according to the initial voltage-frequency command, and feedback a plurality of modified voltage-frequency commands to the AC motor drive, each of the plurality of modified voltage-frequency commands comprising a deviation from the initial V/Hz curve. The control system also determines a real-time value of the motor parameter corresponding to each of the plurality of modified voltage-frequency commands, and feeds back a modified voltage-frequency command to the AC motor drive so that the real-time value of the motor parameter is within a motor parameter tolerance range.
Abstract:
An exemplary display device (2) includes a display body (22) and a support body (23) configured for supporting and moving the display body. The support body includes at least one trolley wheel assembly (28) capable of moving horizontally, and at least one stopper (380) corresponding to the trolley wheel assembly, which is capable of braking the trolley wheel assembly. The display body is moved horizontally when the trolley wheel assembly is moved horizontally.
Abstract:
The present invention relates to a cooling device, mainly comprises a carrying unit, a thermal insulation unit, and a temperature-lowering module. The thermal insulation unit is provided over a part of surface of the carrying unit for blocking heat transmission between the carrying unit and the outside. As the carrying unit is placed on the temperature-lowering module, a cooling chip in the temperature-lowering module is able to lower the temperature of the carrying unit and a biological sample. Furthermore, the thermal insulation unit is able to maintain the temperature of the carrying unit and biological sample, when the carrying unit is removed from the temperature-lowering module. Thereafter, a user can conveniently practice observation and experiment with respect to the biological sample, and avoid damaging the biological sample during experiment or transportation by the use of the cooling device.
Abstract:
An ultraviolet light source includes a casing holding therein UV lamp tubes and a translucent panel above the UV lamp tubes, a filter panel, a side frame surrounding the filter panel, and a hinge connected between the casing and side frame for enabling the filter panel to be turned with the side frame about the axis of the hinge relative to the casing. Moreover, the hinge and the side frame are made of metal material or metal alloy for avoiding breakage of the part of the filter panel connected with the hinge under long radiation of the emitted ultraviolet light. When in use, a bio-sample is placed on the translucent panel, and then the filter panel is closed on the casing over the bio-sample, so that the user can observe the bio-sample or pickup the image of the bio-sample without exposing the body to the emitted ultraviolet light.
Abstract:
