  • Publication number: 20240179029
    Abstract: Approaches in accordance with various embodiments enable communication functionality to be added to an existing hardware component, such as a network interface controller (NIC), data processing unit (DPA), or network switch, rather than requiring an additional component such as a Front Haul Multiplexor (FHM)-type for cellular communications. Such an approach not only avoids the cost and complexity of managing additional hardware components, but can also reduce bandwidth needed for signal transmission. For downlink communications, data can be copied to the relevant radio units of a cell in a single cell deployment architecture to be transmitted to a target client device, such as a cellular handset. For uplink communications, data received from a client device to multiple radio units can undergo decompression and channel estimation before combining the data into a single signal or data stream.

  • Publication number: 20240172882
    Abstract: A vibrational cup device is disclosed that prevents a drink from spilling as ice readjusts within. The vibrational cup device comprises a base component positioned on a bottom portion of a cup and sealed with O-rings. The base component is removable and comprises a rechargeable battery, a micro circuit board, a vibrational motor, a USB port with plug, and a motion sensor that tells the device when the cup is at a 45-to-60-degree angle. At these angles, the vibrational motor would engage for approximately 10 seconds to help break up the ice in the cup or to level out the ice to prevent the sudden release of ice cubes, thus spilling part of the drink.

  • Publication number: 20240173559
    Abstract: It is well understood in the medical industry that medical disorders can manifest as serious problems for the affected subjects, their families, and society. Today, psychiatrists, neurologists and other physicians treat these disorders with a variety of medications, many of which have significant negative side effects. The teachings provided herein are directed to a novel system and methods for treating certain neurological, psychological, psychiatric and medical disorders by delivering a “magnetic stimulation” to a subject's neural and perineural system using either a static or electromagnetic field to generate a modulated variable power multi-spectral magnetic stimulation on three axis; the modulated stimulation using methods that have predictable, controlled, modifiable, and repeatable characteristics.

  • Publication number: 20240173569
    Abstract: A system for delivering ultra-high dose rate irradiation to a target area of a patient, includes a pulsed charged-particle source along a beam axis; a collimator for shaping the beam of radiation; one or more cameras for imaging the target area of the patient; and a dosimetry controller for providing control signals to the charged-particle source one or more dosimeters positioned between an output of the charged-particle source and the collimator in beam fringes for measuring a radiation dosage provided by each pulse; and a beam scanning coil positioned between the collimator and the patient for directing the shaped beam. The dosimetry controller receives feedback from the one or more dosimeters and provides control signals to the particle source and the beam scanning coil that modulate final pulses in the series of pulses in real-time.

  • Publication number: 20240173031
    Abstract: Various systems and methods of delivering an implant to a target location of a body vessel are disclosed. A detachment system can include a tubular body including a lumen extending therethrough and a distal tube on a distal end of the tubular body. A loop wire can be affixed at a first end to the tubular body and can include a loop opening positioned approximate a distal end of the distal tube. A pull wire can extend through the lumen. A hook wire can extend radially through a sidewall of the distal tube and into the lumen. The hook wire can be positioned around a pull wire portion and tensioned such that the pull wire portion abuts the distal tube and provides frictional resistance between the pull wire portion and the sidewall of the distal tube. The frictional resistance can be effective to inhibit premature detachment of the implant.
