A fan module configured to be detachably connected to an electronic device includes an electrical connector and a circuit board assembly. The electrical connector includes a plurality of pins configured to be electrically connected to the electronic device. The circuit board assembly is embedded inside the electrical connector and is electrically connected to one or more of the pins. The circuit board assembly includes a circuit board and an integrated circuit disposed on the circuit board.

A motor-driven compressor includes a rotary shaft, an electric motor, a compression unit, an inverter, a housing, and an inverter case. The housing includes a housing end wall and a housing circumferential wall, which extends from a housing end wall in an axial direction of the rotary shaft. The inverter case includes a case end wall, which extends in the axial direction from the case end wall. The seal circumferential wall includes a proximal end connected to the case end wall and an end face located at a distal end. The housing circumferential wall includes an opposed surface that is opposed to the end face. An annular seal member is provided between the seal circumferential wall and the housing circumferential wall. The seal member extends in a radial direction of the rotary shaft between the end face and the opposed surface.

A system and kit for securing a high-volume low speed (HVLS) fan that secures the control panel to a structural support member and is in turn attached to a mount member. An extension tube extends between and is secured to the mount member and a fan motor shaft. The placement of the control panel near the HVLS system reduces the potential for inadvertent access to the control panel when placed closer to ground level. Inadvertent access can yield to electrocutions and create a fire hazard. Additionally, the aesthetics are greatly improved when the control panel is in alignment with the HVLS supporting structural members.

A ceiling fan remote control device includes a bracket, a remote control, at least one fixation element, and an engaging element. The bracket has at least one mounting hole, an engaging hole, and at least one positioning rod. The at least one mounting hole and the engaging hole are both disposed through the bracket. The at least one positioning rod protrudes from the bracket. The remote control has a receiving groove, a through hole, and at least one positioning groove. The receiving groove and the at least one positioning groove are both formed on the remote control. The through hole is disposed through the remote control. The at least one fixation element passes through the at least one mounting hole. The engaging element passes through the through hole and the engaging hole. The at least one positioning rod of the bracket extends into the at least one positioning groove.

A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.

An inflatable product includes an integrated axial-flow pump which produces a high rate of inflation. The pump includes a cover mounted to a body of the pump and selectively configurable between open and closed positions. In the open position, air is allowed to flow between the inflatable chamber and the ambient air through the pump body. When the cover is closed, the air chamber of the inflatable product is sealed with respect to the ambient air such that air is retained within the inflatable chamber when inflated. A power switch is positioned to be deactivated by the cover when the cover is mounted to the body of the pump, such that replacement of the cover during inflation or deflation of the inflatable product automatically deactivates the pump.

An electric air pump system includes a housing in fluid communication with an inflatable body, a first valve, a first air pump for inflating and deflating the inflatable body, a second air pump for inflating the inflatable body, an air pressure sensor configured to detect the inner pressure of the inflatable body, and first and second prompting devices. The system also includes a control device electrically coupled to the first and second air pumps, the air pressure sensor, and the first and second prompting devices. The first prompting device outputs a first indication signal when the inner pressure is less than or equal to a first air pressure threshold and the second prompting device outputs a second indication signal when the second air pump inflates the inflatable body.

A cooling fan includes: a fan housing; a rotation shaft rotatably supported in the fan housing; a stator fixed to the fan housing; a rotor, which is provided with a magnet that is disposed with a predetermined gap away from the outer circumferential surface of the stator, and which has an impeller connected thereto; and a printed circuit board (PCB) which is installed on a lower side of the stator, and is equipped with a circuit component for controlling the cooling fan and a Hall sensor for sensing the revolutions of the rotor. In order to increase the sensing power of the Hall sensor, the magnet is formed such that the length or the width of the magnet at the lower part thereof that is adjacent to the Hall sensor is larger than that of the other parts of the magnet.

A rotating machine includes a machine housing defining a housing interior, a shaft disposed in the housing interior, with the shaft having a length and an axis extending along the length. The shaft is rotatable about the axis. The rotating machine also includes an impeller wheel disposed in the housing interior and coupled to and rotatable by the shaft, with the impeller wheel having an angular position with respect to the axis. The rotating machine further includes a backplate coupled to the machine housing and having a first side facing the impeller wheel, at least one target element coupled to and rotatable with the impeller wheel, a circuit board coupled to the first side of the backplate and facing the impeller wheel, and at least one sensor disposed on the circuit board for detecting the at least one target element to determine the angular position of the impeller wheel.

A vapor cycle compressor includes a motor section and a compression section operatively engaged with the motor section. A refrigerant path is in the motor section and in the compression section. The refrigerant path includes: a compression refrigerant path, for a single phase compression refrigerant, in the compression section; an inner rotor shaft refrigerant path, for a single phase inner rotor shaft refrigerant, in the compression section and in the motor section; and a stator refrigerant path, for a two phase stator refrigerant, in the motor section.
