  • Publication number: 20250142355
    Abstract: Optimizing beamforming overhead and improving coverage in a radio access network in a wireless communications system (WCS) is disclosed. Herein, a radio node(s) is configured to radiate multiple radio frequency (RF) beams in a coverage area. Notably, the RF beams can intercept a ground since the radio node(s) is mounted above the ground (e.g., on a ceiling) and facing downward toward the ground. As a result, some of the radiated energy may be wasted to degrade coverage and performance in the coverage area. In this regard, in embodiments disclosed herein, multiple reflector devices (passive and/or active) are provided in proximity to the radio node(s) to intercept the RF beams radiated from the radio node(s) and redirect the intercepted RF beams in parallel to the ground. By redirecting the RF beams horizontally, it is possible to reduce energy waste and enhance beamforming coverage in the radio access network.

  • Patent number: 12285265
    Abstract: A system has a body with a base having a top surface with a receiving region to receive the bottom of a single foot. Among other things, the base may be in the form of an open or closed platform with a plurality of temperature sensors in communication with the top surface of the receiving region. The plurality of temperature sensors is within the receiving region and configured to activate after receipt of a stimulus applied to one or both the platform and the plurality of temperature sensors. A comparator is configured to form a temperature range as a function of the temperature value distribution and compare a percentage of the range size of the temperature distribution to a threshold value. An output produces ulcer information indicating the emergence of an ulcer or pre-ulcer when the percentage of the range size equals or exceeds the threshold value.

  • Patent number: 12286839
    Abstract: A cutting element assembly includes a cutter support including a cutter bore. A cutting element is in the cutter bore and a resilient element is integral with the cutter support. The resilient element is longitudinally compressible and has a displacement of greater than 0.1 mm and optionally less than 2 mm. Another cutting assembly includes a cutter support coupled to multiple cutting elements. A resilient element of the cutter support is compressible based on a force applied to the cutter support through one or more of the cutting elements. The resilient element can include a slit in the cutter support. A slit may, for instance, extend perpendicular or transverse to an axis of the cutting elements and allow the cutter support to flex and close off or reduce a size of the slit when forces act on one or more of the cutting elements.
