A portable audio input/output device may include one or more openings that extend through a cover of the device and allow acoustic signals outside a housing of the device to reach a microphone disposed within the housing. The opening(s) may be illuminated by a light guide disposed within the housing, which scatters light emitted from lights disposed within the housing. In some instances, a hole may pass through a printed circuit board to allow acoustic signals to be received by the microphone disposed below the printed circuit board. An input/output (I/O) interface module with multiple buttons and inputs may be installed in the hole. The multiple buttons and I/O ports of the I/O interface module may be aligned along an axis vertical relative to the housing and centered with respect to each other.

An assembling device includes a holding member and a processing device. The holding member is configured to hold a first assembly component and a second assembly component. The processing device is configured to process a first excess thickness portion and a second excess thickness portion. The first excess thickness portion is provided at the first assembly component and is configured to adjust a gap between the first assembly component and the second assembly component. The second excess thickness portion is provided at the second assembly component and is configured to adjust the gap.

Occlusive devices and associated methods of manufacturing are disclosed herein. Manufacturing an occlusive device can include conforming a mesh to a forming assembly and setting a shape of the mesh based on the forming assembly. In some embodiments, the forming assembly comprises multiple forming members, a mandrel, and/or one or more coupling elements. The method may include everting the mesh over the forming assembly such that the mesh encloses an open volume with a shape based, at least in part, on the shape of the forming assembly. According to some embodiments, setting a shape of the mesh comprises heat-treating the mesh and forming assembly.

A hub puller kit for pulling hubs off of power ends of frac pumps, and a method of removing a hub from a pinion shaft of a power end using the hub puller kit. The hub puller kit has an adapter flange formed out of a monolithic body with fastener openings, and a hydraulic actuator coupled to the adapter flange. The adapter flange has a stepped surface formed on a first surface and a recessed surface formed in a second surface, and a central opening having a threaded flange portion that extends from the stepped surface to the recessed surface. The hydraulic actuator has a hydraulic cylinder and a hydraulic plunger disposed at least partially within the hydraulic cylinder, and a threaded actuator portion that engages the threaded flange portion to couple the hydraulic actuator to the adapter flange.

Apparatuses for removing a circumferential seal from the internal wall of a pipe comprise a tool for forward movement into an entry end of the pipe towards and into contact with the seal in the pipe, the tool having means for engaging the seal with the forward movement and with further forward movement of the tool release of the seal from the pipe wall and means for capturing and retaining the released seal with still further forward movement whereby on subsequent rearward movement of the tool the seal is withdrawn from the entry end of the pipe.

Various embodiments of a storage system for use with weight distribution trailer hitches are disclosed. The storage system would be used by someone with a towing vehicle, a boat or RV, and a trailer hitch to link these two. During the times these items are not in-motion, these weight distribution hitches have large parts and take up a lot of space. Such a customer can put their extra hitch-parts in the storage system, which keeps the weight distribution system nicely stored for example on the trailers beams AKA the trailer's A-frame rails or frame.
