Abstract: In one embodiment, certain aspects of forces at a structural interface applied by one actuator are mitigated by a secondary actuator that applies a secondary force. In some embodiments the secondary actuator applies a static force. In yet another embodiment, an actuator is used to apply a force on a wheel assembly of a vehicle to detect and/or ameliorate the effect of certain tire incongruities.

Abstract: A toy includes a hollow soft plastic shell deformable by means of squeezing, first modeling piece configured on the hollow soft plastic shell and second modeling piece coupled pivotally to the first modeling piece; the hollow soft plastic shell has a top wall arched downward to form an accommodation concave chamber. The present invention is novel in structure, interesting, energetic and easy to be operated and controlled. In addition the toy of the present invention is easy to be produced and manufactured because of the simple structure thereof, very stable in use, and suitable for the promotion, production and application so as to meet entertainment, teaching, trick or other needs.

Abstract: An umbrella tip structure for vertical placement of an umbrella is disclosed, including a fixed pillar, a movable barrel, a spring, and at least two tip blades. The umbrella tip structure is mountable to an umbrella in such a way that tip blades can be automatically expanded and/or collapsed so that in use, with a movable barrel positioned against a horizontal surface, the tip blades may be opened automatically to make the umbrella tip structure a stable and firm support stand that stably and firmly supports the umbrella in a vertical, upright condition on a horizontal surface, achieving vertical placement of the umbrella. The operation and use of the umbrella tip structure is simple and easy.

Abstract: An eccentric wheel structure of a wind up toy car includes a base, a casing and a wind up motor. The wind up motor is disposed between the base and the casing. The wind up motor includes a wheel axle and two wheels. The wheel axle is inserted through the wind up motor. The two wheels are coupled to two sides of the wheel axle. Particularly, the two wheels are eccentric relative to the wheel axle. When the wheel axle is turned, the wind up toy car is staggered to move by the two eccentric wheels. Compared to a traditional wind up toy car that is erect to move, the present invention is more funny and special.

Abstract: A swing-type removable toy includes a casing and a motor disposed in the casing. An output end of the motor is connected with a gear unit. The gear unit is further connected with a wheel unit. The wheel unit includes a driven gear, a wheel axle and two wheels. The driven wheel meshes with the gear unit. The wheel axle is inserted through the driven gear. The two wheels are coupled to two ends of the wheel axle. The two wheels are eccentric relative to the wheel axle. When the wheel axle is turned, the toy is staggered to move by the two eccentric wheels. Compared to a traditional toy that is erect to move, the present invention can attract more consumers.

Abstract: An automotive radar device and an antenna cover are disclosed. The automotive radar device includes a base, an antenna disposed on the base, and the antenna cover. The antenna cover includes a main portion and an engagement portion connected to the circumference of the main portion. The engagement portion can be engaged to the base such that the main portion covers the antenna. Therein, a thickness of the main portion along a radiation direction of the antenna is equal to half-wavelength corresponding to a center operation frequency of the antenna under a dielectric constant of the main portion. Thereby, energy radiated from the antenna can mostly pass through the main portion without excessive signal attenuation, which solves the insufficient signal intensity due to a protection cover in the prior art. Further, the main portion can be made of flexible and weather resistant material to improve its physical and chemical properties.

Abstract: The present disclosure discloses a clamshell electronic device including an upper cap, a bottom lid, a first battery, a second battery, a sensing device and a control device. When the clamshell electronic device is under a working state, the first battery provides a system operating voltage to the clamshell electronic device, and the first battery provides a system operating voltage to the clamshell electronic device. When the clamshell electronic device is under a first state, the second battery provides a booting voltage to the clamshell electronic device, and the sensing device produces a first trigger signal according to the upper cap flipped up from the bottom lid. The control device is coupled to the sensing device, and enables the system operating voltage to be provided to the clamshell electronic device according to the first trigger signal, such that the clamshell electronic device enters the working state from the first state.

Abstract: A wireless signal transceiver for a blind spot detection system includes a first substrate, a radio-frequency processing unit formed on the first substrate for transmitting a wireless signal and receiving a reflecting signal of the transmitted wireless signal, and a complex programmable logic device controlled by a digital signal processor for controlling operations of the radio-frequency processing unit according to at least a control command of the digital signal processor, so as to detect whether an object exists within a specific range.

Abstract: A vibrating crawl toy includes a housing. The housing includes a vibration motor therein. The vibration motor is located at a front end or a rear end of the housing. The housing further includes at least two rows of legs at a bottom thereof. The housing includes the vibration motor which is located at the front end or the rear end of the housing and the legs which are located at the bottom of the housing and used to walk. The vibration of the vibration motor brings the housing to sway and the housing brings the legs to advance on a table or on the ground, imitating walking of an animal. In particular, the present invention imitates an insect to crawl, enhancing amusement and fun.
