The filter housing assembly has a top portion with an ingress port and egress port extending therefrom, and a protrusion extending from the filter housing longitudinally axial center. The ingress and egress port are formed in an hourglass shape. A filter key having a base with a groove for mating with said projection, at least one finger extending from said base, and an electronic circuit component housing attached thereto for receiving a printed circuit board, is connected to the filter housing top portion by mating said top portion protrusion with the filter key groove. Both of said ingress and egress port have at least one cavity for the passage of fluid therethrough, where each cavity is exposed in a direction facing away from the printed circuit board.

Abstract: In a perforating gun, shaped charges can be configured to be rotatable with respect to each other and can be secured in a predetermined phasing by an alignment rod that can be helical with a pitch that defines the phasing. The shaped charges can be supported by holders, which can be directly connected to each other to be infinitely rotatable and can also be attached to and/or retained by the alignment rod via alignment connectors. The alignment connectors can also be configured to hold detonation and signal cords. This shaped charge alignment approach can facilitate manufacturing and assembly, for instance since a single design of holders and other components of the assembly can be used with various different alignment rods to provide the desired phasing based on well design criteria.

Abstract: Described herein are embodiments of a pressure hose having an improved reinforcement layer. In some embodiments, the reinforcement layer of the pressure hose has a reinforcement volumetric ratio (RVR) of greater than or equal to 110%. The reinforcement layer can include a plurality of braided beams, with each beam comprising a plurality of ends. In some embodiments, the plurality of ends within a beam are arranged in a multi-layer orientation. In some embodiments, the number of ends and the end orientation within each beam is identical amongst all beams in the reinforcement layer. The shape, size, and arrangement of the ends within a beam can all be adjusted to increase the surface area to volume ratio and, correspondingly, the RVR of the reinforcement layer.

Abstract: Wearable devices for sensing neuromuscular signals using a small number of sensor pairs are disclosed. One example wrist-wearable device includes eight pairs of neuromuscular-signal sensors. Each pair of neuromuscular-signal sensors is positioned over a portion of a wrist of a user while the wrist-wearable device is worn by the user. Each pair of neuromuscular-signal sensors further includes a first and second electrodes configured to be used as a differential sensor of neuromuscular signals travelling through the wrist of the user, and electrical signal-processing circuitry configured to amplify and filter neuromuscular signals received from the first and second electrodes to produce processed neuromuscular signals. The wrist-wearable device also includes a shared ground electrode configured to ground both the first and second electrodes.
