Abstract: A double-layer blade ceiling fan capable of adjusting the arrangement of blades includes a motor and at least two blades. The motor has a stationary part and two rotating parts. The rotating parts are spaced apart from the stationary part. The rotating parts each have a plurality of mounting portions that are arranged around a central axis of the motor. The stationary part has an upper connecting portion and a lower connecting portion. The mounting portion is configured for connection of one of the blades. At least one of the blades is fixed to each of the rotating parts. The blades mounted to the rotating parts are selectively arranged in a same or different pattern for regulating air flow. When the blades and the rotating parts are rotated, the upper connecting portion and the lower connecting portion are not affected.

Abstract: A motor and blade mounting structure of a ceiling fan, the ceiling fan has a motor, at least one bracket, and at least one blade. The at least one bracket has at least one mounting portion. The mounting portion of the at least one bracket is configured for mounting the at least one blade. The motor has a rotor. The rotor of the motor is fixedly connected to the at least one bracket. The motor and blade mounting structure enhances assembly convenience, safety, structural support and durability.

Abstract: An example portable computer disclosed herein includes a first housing, a keyboard carried by the first housing, a second housing pivotally coupled to the first housing, a display carried by the second housing, a wireless charger, and a pad to carry the wireless charger. The pad is pivotally coupled to the first housing. The pad is moveable relative to the first housing between a first orientation to position the wireless charger above the first housing and a second orientation to position the wireless charger adjacent the first housing. The pad to support a body part of a user adjacent the keyboard when the pad is in the first orientation. The pad is to support an external electronic device proximate the wireless charger when the pad is in the second orientation.

Abstract: For transformer fault detection, a method generates a transition region that separates a health region and a fault region in a two-dimensional feature space of two feature indicators for a plurality of operation conditions using a fault detection model for a power transformer type. The method determines the feature indicators of a given power transformer of the power transformer type. The method determines whether the feature indicators in the transition region satisfy a fault condition. The method predicts an inter-turn short fault for the given power transformer in response to satisfying the fault condition or the feature indicators being in the fault region.

Abstract: A quick assembling structure includes a first seat, a second seat, and two elastic plates. The first seat and the second seat are configured to be coupled to a ceiling fan body and a lamp. The first seat has two bars. The second seat has two bar entrances, two longitudinal grooves, and two guide grooves. The elastic plates are disposed in the respective guide grooves, and each have a contact portion and a holding portion. When in use, the bars of the first seat are inserted into the bar entrances, the longitudinal grooves and the guide grooves, the bars are pushed to pass through the contact portions of the elastic plates, and the bars are secured between the contact portions and the holding portions of the elastic plates and the guide grooves.

Abstract: A ceiling fan has blades spaced apart circumferentially about and extending outward radially from a rotating component of a motor. The blades include upper blades and lower blades. Each lower blade is between and extends below a pair of adjacent upper blades. The motor, when activated, rotates the rotating component, concurrently rotating the upper blades and the lower blades in the same rotational direction. Each of the upper blades leading an adjacent one of the lower blades is configured to generate and direct an air current rearwardly and downwardly therefrom in front of the adjacent one of the lower blades and each of the lower blades trailing an adjacent one of the upper blades is configured to intercept the air current from the adjacent one of the upper blades and accelerate it rearwardly and downwardly therefrom, when the motor is activated.

Abstract: There is disclosed in one example a heat dissipator for an electronic apparatus, including: a planar vapor chamber having a substantially rectangular form factor, wherein a second dimension d2 of the rectangular form factor is at least approximately twice a first dimension d1 of the rectangular form factor; a first fan and second fan; and a first heat pipe and second heat pipe discrete from the planar vapor chamber and disposed along first and second d1 edges of the planar vapor chamber, further disposed to conduct heat from the first and second d1 edges to the first and second fan respectively.

Abstract: Apparatus, systems, articles of manufacture, and methods are disclosed for physical keyboards with multi-display computing devices. An example keyboard includes a plurality of keys and a translucent backplate having a first side and a second side. The example keyboard also includes a coating between the first side of the backplate and the plurality of keys, the coating to pass light to illuminate the plurality of keys, and the coating to obscure the plurality keys when viewed from the second side of the backplate.

Abstract: A ceiling fan having double-layer blades includes a motor unit, a blade frame unit, a first blade unit, and a second blade unit. The blade frame unit has a blade frame body. The first blade unit includes a plurality of first blades. The second blade unit includes a plurality of second blades. The first blades and the second blades surround the outside of the blade frame body, so that there is no need for the motor unit to provide a motor housing for connecting the first blades and the second blades, thereby saving costs and installation costs. With the arrangement of the first blades and the second blades, the ceiling fan can increase the current of air for cooling.
