  • Efficient detection of ranging code correlation function of a GNSS signal
    Patent number: 10884136
    Abstract: A ranging code correlation function detection system for use in a global navigation satellite system (GNSS) receiver includes a correlation block to correlate a digitized GNSS signal (e.g. at or above a critical sampling rate) with a corresponding ranging code at each of a plurality of different offsets from a current estimate of a code delay to generate a plurality of correlation data points; an interpolation filter configured to generate at least one estimated correlation data point that lies between two of the correlation data points based on the current estimate of the code delay. In some cases the ranging code correlation function detection system may also include a discriminator block configured to generate an updated estimate of the code delay based on the at least one estimated correlation data point.

  • Pig loader device
    Patent number: 10876673
    Abstract: A pig loader device can include a breech assembly having a chamber body, a ramrod compartment, a breech, and a neck. A ramrod having a push plate, a rod, and a breech plate may be disposed within the ramrod compartment and configured to slideably traverse the ramrod compartment and the breech. In use, the device can be connected to an ancillary pipe via the neck, and a pig may be placed within the breech and aligned be to be slid within the breech and neck upon engagement with the ramrod to facilitate pigging operations of a pipeline. The ramrod may then be forced forward to an extended position, thereby urging the pig through the neck to be seated within the pipe. The device may then be detached from the pipe to enable continued pigging operations.

  • METHOD AND DEVICE FOR VERIFICATION OF INTRA-LUMINAL PLACEMENT AND PATENCY FOR VASCULAR ACCESS DEVICES
    Publication number: 20200390340
    Abstract: Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. In one form, our device itself remains non-invasive, connecting at the vascular access device's hub outside the patient's body. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal is generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same.

  • DECODER FOR LOW-DENSITY PARITY-CHECK CODES
    Publication number: 20200358456
    Abstract: Methods and apparatus for decoding LDPC code provide that an LDPC code may be represented as a Tanner graph comprising bit nodes and check nodes and connections between them. A configurable LDPC decoder supporting many different LDPC codes having any sub-matrix size includes several independently addressable memories which are used to store soft decision data for each bit node. The decoder further includes a number P of check node processing systems which generate updated soft decision data. The updated values are then passed back to the memories via a shuffling system. If the number of check nodes processed in parallel by the check node processing systems is PCNB (where P?PCNB) and the soft decision data for a bit node is of word size q bits, the total width of the independently addressable memories is larger than PCNB*q bits.

  • Intelligent heterogeneous wireless handoff
    Patent number: 10750420
    Abstract: Provided are methods and systems of managing vertical handoffs in a wireless communication network. Embodiments include analyzing wireless device usage to determine usage patterns, which may include locations and times at which the wireless device is typically accessing the network. The network may recognize points in the usage patterns at which signal quality parameters are typically reduced. Such reductions in signal quality parameters may lead to inefficient vertical handoffs. The network may decrease adverse effects of inefficient vertical handoffs by reducing ping ponging, selecting links between wireless devices and network nodes, or indicating to a user of the wireless device that delays and/or data loss may occur.

  • IQ imbalance estimator
    Patent number: 10693513
    Abstract: An IQ amplitude balance estimator is described herein which uses a positive frequency mixer to generate two outputs. The first output is the standard output from a positive frequency mixer and the second output corresponds to a spectrum inverted output from a negative frequency mixer. The second output is generated, however, using the same partial products as the first output and no negative frequency mixer is used. An IQ amplitude imbalance metric is generated by taking the real part of the output from correlation logic which performs a correlation of the two outputs from the mixer. This metric may then be used in a closed loop to compensate for any IQ amplitude imbalance.
