Abstract:
A keyboard includes a key frame, a support frame, a circuit board, a buffer and noise reduction pad, and a plurality of keys. The key frame and the support frame are assembled with each other. The circuit board is mounted to the bottom surface of the support frame. The buffer and noise reduction pad is abutted against the bottom surface of the circuit board. The keys are inserted through the key frame and the support frame. As such, when the key is pressed, the vibrations and noise generated by the key are counteracted and absorbed by the buffer and noise reduction pad, thereby reducing the intensity of the vibrations and noise and achieving buffer and noise reduction effects.
Abstract:
A control device capable of providing rotational damping through a magnetic force is provided directly at the base of an electronic product and includes a supporting member, an adjusting member, and two magnetic members. The supporting member is provided at the base. The adjusting member is rotatably provided on the supporting member. The adjusting member has a bottom portion corresponding to a switch pre-installed in the base. The adjusting member further has a head portion outside the base. The two magnetic members are provided on the supporting member and the adjusting member respectively. The two magnetic members generate a magnetic force therebetween and thereby change the rotational damping between the supporting member and the adjusting member.
Abstract:
An electric wheel hub is provided. The electric wheel hub includes a shell, a motor assembly and a battery unit. The motor assembly is disposed in the shell and has a stator, a rotor and a shaft. The shaft is detachably inserted within the stator. The rotor is rotatable with the shell and rotatable relative to the stator. The battery unit is disposed in the shell and electrically connected with the motor assembly. The battery unit has a cartridge and batteries positionally received within the cartridge.
Abstract:
A press-key with a multiple-trigger mechanism includes a base, an alphanumeric key assembly, and at least two elastic members. The alphanumeric key assembly includes a coupling assembly provided on the base. The at least two elastic members are provided on the base and under the alphanumeric key assembly. One of the elastic members has a different height from the remainder of the elastic members. When the alphanumeric key assembly is moved toward the base, the elastic members are separately driven by the alphanumeric key assembly to press and thereby activate a switch such that different electrical signals are generated. The operability and trigger response of the press-key can be flexibly adjusted according to user needs so that the press-key can be operated rapidly and respond in real time.
Abstract:
A control device capable of providing rotational damping through an elastic force is provided directly at the base of an electronic product and includes an adjusting member and an elastic member. The adjusting member is rotatably provided at the base. The adjusting member has a bottom portion corresponding to a switch provided in the base. The adjusting member further has a head portion outside the base. The elastic member is provided between the adjusting member and the base. The elastic force of the elastic member acts between the head portion of the adjusting member and the base to change the rotational damping to which the adjusting member is subjected.
Abstract:
A vehicle-mounted device and a fleet management system are disclosed. The vehicle-mounted device is mounted in a vehicle equipped with an OBD module that provides vehicle status parameters, including a sensor module mounted in the vehicle, a sensor module mounted in the vehicle and used to detect the real-time driving status image and driver status image of the vehicle, a general control module electrically connecting the sensor module and the OBD module for receiving the vehicle status parameters of the OBD module and the real-time driving status image and driver status image of the vehicle, and a judgment module electrically connected to the general control module to judge whether the driving of the vehicle complies with the driving specifications according to the data received by the general control module.
Abstract:
A method for identifying and determining a physiological characteristic using invisible light includes the steps of: respectively activating at least two light-emitting units to emit an invisible light onto a human body to be detected in such a manner that only one light-emitting unit is activated at a time wherein each of the at least two light-emitting units is configured to emit a different wavelength of invisible light, then capturing a real-time image signal from the human body corresponding to the invisible light emitted by each light-emitting unit and reflected by the human body, and then analyzing each real-time signal and defining a skin area according to the analysis result, and finally calculating the change of reflected light intensity of the skin area to obtain a measured value corresponding to the physiological characteristic of the human body.
Abstract:
A pressure sensing device includes an elastic tube defming a chamber and an opening in one or each of two opposite ends thereof in communication with the chamber, and a pressure sensor component sealed in the opening in one or each end of the elastic tube for detecting a change in air pressure in the chamber when the elastic tube is compressed by an external pressure. The pressure sensing device can be used under a waterproof or dustproof environment, or embedded in a bed mattress or seat cushion and incorporated with a signal processor for detecting changes in the biophysical condition of the user, or embedded in a floor mat and incorporated with light and/or sound generating device for reminding your home or store that someone is coming in or going out. Thus, the pressure sensing device has the characteristics of simple structure, practical applicability and wide application range.
Abstract:
A user login method and system capable of analyzing user face validity is disclosed to request the user provide a digital authentication information containing the username and password and to simultaneously capture the user face instant video streaming, and then to analyze and obtain the valid physiological characteristic information of the user face instant video streaming, and then to get the valid face image from the captured user face instant video streaming, and then to output the valid physiological characteristic information, the valid face image and the digital authentication information for use as valid login credentials, improving the authenticity and accuracy of the login credentials.
Abstract:
A tablet computer protective case with a keyboard includes an outer cover, an inner cover, a zipper, a partition, and two elastic members. When in use, the protective case is placed on a support plane and the zipper is unzipped to open the inner and outer covers. The keyboard is placed in an inner bottom concave cover of the inner cover, and the tablet computer is placed in an inner top concave cover of the inner cover. After that, a third upper support portion of the inner top concave cover of the inner cover is folded outward relative to a third lower support portion. The first upper support portion of the outer top concave cover of the outer cover is also folded outward relative to a first lower support portion. A second upper support portion of the partition is folded outward relative to a second lower support portion. One side of the outer top concave cover of the outer cover, away from the outer bottom concave cover, leans against the support plane and is supported by the two elastic members, so that the tablet computer and the keyboard form an obtuse angle for the user to use the keyboard and the tablet computer conveniently.
