Abstract: Horizontal motion conveyors for moving material and methods for reversing such horizontal motion conveyors are disclosed. In some embodiments, the horizontal motion conveyor includes a motor such as a servomotor that is connected to the driveshaft that drives the horizontal motion of the conveyor. In some embodiments, the speed profile of the pan may be changed to reverse direction of the flow of material on the pan without slowing or stopping the drive motor.

Abstract: Various embodiments provide a cardiac mapping method including: generating an activation map of a heart based on electrocardiogram (ECG) data of a heart and a three-dimensional (3D) heart model; performing an electrophysiology (EP) procedure to determine a first pacing location; pacing the heart at the first pacing location using an EP catheter; determining whether the pacing at the first pacing location generates a desired cardiac response; displaying guidance information related to a second pacing location on one or both of the activation map and the internal surface map, when the first pacing location is determined not to generate the desired cardiac response; moving the pacing catheter to the second pacing location, based on the guidance information; and pacing the heart at the second pacing location.

Abstract: A firearm stock with barrel-centering feature has an elongated body defining an elongated receiver channel and an elongated barrel channel, the receiver channel defined in part by a flat floor surface facing in upward direction, the receiver channel defined in part by opposed sidewalls extending above the floor surface, a fastener facility at the rear of the receiver channel operable to connect to the tang of the receiver, and a lateral adjustment facility forward of the fastener facility and operable to secure the receiver in a selected lateral angle of pivot about the fastener facility, such that the barrel is centerable within the barrel channel to avoid the barrel touching the stock. The lateral adjustment facility may include a set screw having an axis parallel to the floor surface of the stock. A pair of set screws opposing each other may secure the action in a selected lateral position.

Abstract: A optical target assembly is disclosed herein. The optical target assembly is movable about orthogonal pitch, yaw and roll axes and includes a reflector, a pitch and yaw angular sensor assembly, and a roll sensor assembly. The reflector is configured to engage a source of laser light. The pitch and yaw angular sensor includes a laser light sensor and an angle detection sensor. The pitch and yaw angular sensor assembly is configured to measure 360 degrees of motion about the pitch and the yaw axes. The roll sensor assembly is configured to measure 360 degrees of motion about the roll axis. The reflector can include an aperture configured to permit a portion of laser light incident on the reflector to pass through the reflector and onto the laser light sensor. The roll sensor assembly can include a roll angle sensor and a roll level sensor coupled to a two-dimensional pendulum.

Abstract: A firearm sight assembly comprises a rear base. The firearm sight assembly comprises a rear sight element movable with respect to the rear base between a lowered condition and an elevated condition. The rear sight element has a first pair of upwardly projecting first rear posts defining a first notch therebetween when in the lowered condition. The rear sight element has a second pair of upwardly projecting second rear posts defining a second notch therebetween when in the elevated condition. The first rear posts extend to a first height above the rear base, and the second rear posts extend to a second height above the rear base. The second height is greater than the first height.

Abstract: Various embodiments include a catheter positioning device that may include a sled member, a sled base, an active damping system, a sensor, and a control system. The sled member may be configured to accept a handle of a catheter. The sled base may be configured to move the sled member along a length of the sled base for positioning the catheter within a patient. The active damping system may be configured to apply a force to the sled base to resist movement of the sled base in response to a control signal. The sensor may be configured to generate signals in response to a movement of the sled base. The control system may be configured to receive sensor signals from the sensor and transmit control signals to cause the active damping system to apply the force to resist movement of the sled base indicated in the received sensor signals.

Abstract: Various embodiments enable an introducer for a catheter to be rotated around an axis and/or traversed backward and/or forward along the axis. In various embodiments, positioning of an introducer may be enabled by an introducer support configured to be rotated around an axis and/or extended or retracted along the axis. The introducer may be manually operated and/or operated by motors in a nose cone of a catheter positioning system. In various embodiments, a portion of the introducer support may be configured to flex. In other embodiment, positioning of an introducer may be enabled by an adjustable nose cone of a catheter positioning system.

Abstract: Various embodiments provide a cardiac mapping method including: recording premature ventricular contraction (PVC) electrocardiogram (ECG) data during PVC of a heart; generating a PVC activation map of the heart, based on the PVC ECG data and a three-dimensional (3D) heart model generated based on two-dimensional (2D) images of the heart, the PVC activation map including an area of earliest activation; generating a reference image by modifying on one of the 2D images to identify the area of earliest activation; displaying both the PVC activation map and the reference image; and pacing the heart at a first pacing location disposed in the area of earliest activation.

Abstract: Apparatuses, systems and methods associated with an instrument for testing of an audio device are described herein. In embodiments, a module to be coupled to an analyzer may be described. The module may include an antenna, communication circuitry coupled to the antenna, and processor circuitry coupled to the communication circuitry. The processor circuitry may be to receive an indication of a configuration for the module, configure the module in accordance with the configuration, cause the communication circuitry to establish a wireless connection between the module and a device under test (DUT), and cause the communication circuitry to perform a test procedure for the DUT via the wireless connection. Other embodiments may be described and/or claimed.

Abstract: A gear box includes a casing having a partition portion, a supporting shaft fixed to the partition portion, and an output shaft supported so as to be rotatable around the supporting shaft and to which a pinion gear is fixed. The casing has a division wall that is positioned in the ?Z direction with respect to the partition portion and is capable of abutting against the supporting shaft. The division wall constitutes a portion of a motor accommodation portion for accommodating a motor.
