An electrical stator surrounds the electric rotor. The electric stator includes a seal configured to isolate stator windings from an outside, downhole environment. An inner surface of the seal and an outer surface of the electric rotor define an annulus exposed to the outside environment. A bearing couples the electric rotor to the electric stator. A lubrication system is fluidically coupled to the downhole-type device. The lubrication system includes a topside pressure pump and a downhole-type distribution manifold configured to be used within a wellbore. The distribution manifold is fluidically connected to the topside pressure pump and the bearing to receive a flow of lubricant from the topside pressure pump. |

Integrated accessible battery compartment for motorized window treatment
A battery-powered window treatment, such as a roller shade, may include a battery compartment that provides access to batteries while the window treatment is assembled and mounted to a structure. The battery compartment may be pivotally supported by a housing of the window treatment, and operable between opened and closed positions. The batteries may be concealed when the battery compartment is closed, and may be accessible when the battery compartment is open. The battery compartment may be operated opened and closed while a shade of the window treatment is at any position, such that removal of the batteries does not result in the loss of tracking information for the shade. The window treatment may include a fascia that is operably connected to the battery compartment, such that when the battery compartment is opened, the fascia does not obstruct access to the batteries, and does not interfere with the shade. |

In-vehicle device for controlling a movable barrier operator
In one aspect, an in-vehicle device is provided that includes a sensor configured to detect a vehicle characteristic indicative of the vehicle being in proximity to a location associated with a movable barrier operator. The in-vehicle device includes communication circuitry to communicate an open command to the movable barrier operator that causes the movable barrier operator to open a movable barrier connected to the movable barrier operator. A memory is configured to store a vehicle arrival condition indicative of whether the vehicle arrived at the location associated with the movable barrier operator. A processor is configured to determine satisfaction of the vehicle arrival condition and, upon the vehicle arrival condition not being satisfied, cause the communication circuitry to communicate a close command to the movable barrier operator that causes the movable barrier operator to close the movable barrier. |

Spindle drive assembly, vehicle flap with a spindle drive assembly and method for installing a spindle drive assembly
A spindle drive assembly for opening and/or closing a vehicle flap including a spindle drive assembly housing extending along a spindle drive axis and, between its axial ends, a stop section acting axially on both sides. A motor gear unit is arranged on a first side of the stop section and a spindle unit is arranged on a second side of the stop section. Furthermore, a vehicle flap with such a spindle drive assembly. In addition, a method of assembling a spindle drive assembly. |

Opening and closing body drive mechanism
An opening and closing body drive mechanism that drives an opening and closing body between an open position and a closed position; a drive unit to drive the opening and closing body; a detecting unit to detect movement of the opening and closing body; and a control unit to control driving of the opening and closing body. The control unit carries out a feedback control to control driving of the opening and closing body such that the movement of the opening and closing body, detected with the detecting unit, matches a predetermined target value when no abnormality occurs in the detecting unit or in wiring connecting the detecting unit and the control unit. |

Keyless access for commercial vehicles
A commercial vehicle used for parcel delivery is installed with a control module. The control module communicates wirelessly with a transmitter to give control to the vehicle operator. The vehicle operator can access the vehicle's cargo compartment through the bulkhead door and/or the rear door solely by using the transmitter as opposed to manually actuating the door latch. A door actuator is added to the bulkhead door such that when the bulkhead door is wirelessly actuated the door opens without operator assistance, and the process of the door opening does not damage the vehicle. Additionally, the vehicle operator can initiate the control module to allow a push-button start and stop of the vehicle's ignition system. Such elements contribute to time savings and cost savings for parcel delivery operators. |

Refrigerator
Disclosed is a refrigerator with a storage space. The refrigerator includes a main body including a storage space, a door configured to open and close the storage space, and a hinge provided under the door and configured to rotatably couple the door to the main body. The hinge includes a linear member accommodator configured to accommodate therein a linear member drawn out from the door, and a cut-out portion hollowed and configured to extend along a hinge axial direction to allow the linear member accommodator to communicate with an outside at one side. |

Systems and methods for improving window safety
A system for improved window fall prevention provides removable attachment of a window screen frame to a window frame. Systems according to the disclosure provide removable attachment of a window screen frame to an anchor positioned in the window frame by means of a plurality of cables. The cables attach to the screen frame or rest against an exterior portion of the screen frame at an exterior end, are threaded through the screen frame, and include on an interior end, opposite the exterior end, a releasable attachment to the window frame anchor. The releasable attachment may be between a loop of cable formed at the interior end and the window frame anchor, where the window frame anchor may be a T-screw. |
