Abstract: A blender tub for hydraulic fracturing operations and associated components are provided. A spinning proppant distributor located above the blender tub liquid level interrupts and redirects falling granular proppant material (e.g. sand) into the tub. A fluid intake channel wraps around at least part of the blender tub outside wall and introduces liquid (e.g. water) into the blender tub via a plurality of channels. The liquid is introduced with a force and angle which imparts a vortex within the blender tub. The above aspects facilitate blending of material within the tub.

Abstract: Techniques to improve the immunity of wireless battery systems by transmitting heavily-coded signals, e.g., using multiple chips of a sequence for each bit of information, to trade data rate for interference or jamming immunity as a response once a noisy environment is identified. The techniques provide the system with a noise immunity operating mode (or high-immunity transmit and receive mode) that can improve resilience to interference or jamming by reducing the data rate. One option for reducing the data rate is by slowing down the transmission bit rate to reduce the occupied transmit bandwidth to minimize the probability of collisions with interfering signals. Another option is though digital coding methods using Forward Error Correction such as Convolutional Coding, Reed-Solomon Coding and Turbo coding. A third option is with RF spread spectrum techniques such as Direct Sequence Spread Spectrum (DSSS) or Frequency Hopped Spread Spectrum (FHSS).

Abstract: Apparatuses (1) for mapping devices (21-29) to representations (31-39) of the devices (21-29) in models comprise displays (11) for displaying representations (31-39), memories (12) for storing triggering information defining triggering procedures for triggering the devices (21-29), inputs (16) for receiving identifying information comprising identifiers from devices (21-29) that have been triggered, and processors (14) for linking the identifiers and the representations (31-39) at the hand of the triggering procedures. The commissioning of devices (21-29) is done faster and more user-friendly. The triggering procedures may define the devices (21-29) to be triggered in a sequence.

Alternatively the triggering procedures may define unique codes to be allocated to the representations (31-39) and to be provided to the devices (21-29), with the identifying information further comprising the codes.

Abstract: Embodiments of the present disclosure provide systems and methods for maintaining timing precision in different operating modes of a device (e.g., a wireless node). A timing circuit may switch clock signals between two different modes (e.g., high power and low power) while preserving timing precision. In a high-power mode, the timing circuit may provide a high frequency clock signal, and in a lower-power mode, it may provide a low frequency clock signal. Moreover, the switching between the different clock signals may be synchronized to select edges of the low frequency clock signal.

Abstract: A medical instrument includes a handle, a trocar in communication with the handle, and a cannula in communication with the trocar and the handle. The cannula is engaged (locked) with the handle when linearly displaced proximally towards the handle and, the cannula is disengaged (unlocked) from the handle when linearly displaced distally away from the handle. The cannula is linearly reciprocated, between the locked position and the unlocked position, along a linear travel path defined parallel to a longitudinal axis of the trocar such that the cannula is prohibited and permitted to articulate about the longitudinal axis of the trocar, and relative to the handle, respectively. Advantageously, the cannula is locked and unlocked from the trocar by without requiring an external force exerted generally transverse to trocar and/or cannula, thereby permitting a user to lock/unlock the cannula, relative to the trocar, with one hand.
