  • Patent number: 12241051
    Abstract: This disclosure describes methods and apparatuses for creating or using a fibrous cell substrate that is formed in a mold using temperature and wettability gradients and that upon which cells can be grown. The disclosed method can include utilizing a temperature gradient and a wettability gradient within a mold to form a porous cell substrate. In particular, the temperature and wettability gradients control nucleation and growth of crystals within the cell substrate solution to form parallel layers of cell substrate. The crystals can be sublimated by freeze drying and the porous cell substrate is seeded. More specifically, the disclosed method includes using pressure and an increased cell mixture viscosity to seed cells deep within the cell substrate. This disclosure also describes an apparatus for forming the structured porous cell substrate.

  • Publication number: 20240082472
    Abstract: A blood treatment system with pressure sensors may be configured to control blood flow to and from the patient and use readings of the pressure sensors to determine a change in a pressure drop across a flow restriction in the blood circuit to estimate a condition of the machine or the patient, or outputting data responsive to the estimation. Further embodiments employ measurement of pressure drop to detect abnormal viscosity or viscosity variations in order to detect possible infection.

  • Patent number: 11697965
    Abstract: A ladder safety mechanism comprises at least one clamp, preferably a pair of spaced apart clamps, attachable part way along a ladder, to secure the ladder to part of a structure. In some embodiments, the mechanism includes at least one manually operated actuator, such as a rope or cable, coupled to the at least one clamp to enable a user located at the bottom of the ladder to open the at least one clamp to receive the part of a structure. In some embodiments, the at least one clamp is automatically secured to the part of the structure by placing the clamp onto the structure. The at least one manually operated actuator also enables a user located at the bottom of the ladder to open the at least one clamp to release the part of the structure. The at least one clamp is oriented substantially perpendicularly to a part of the structure to which the ladder is to be attached.

  • Patent number: 11397083
    Abstract: Gyroscope data can be used to generate upsampled signal. Multiple mobile devices are spaced apart from each other in a spatial arrangement. Each mobile device includes a gyroscope sensor to detect mechanical vibrations caused by signals originating within a vicinity of a mobile device that includes the gyroscope sensor. Each mobile device includes one or more respective processors to receive representations of the mechanical vibrations sensed by the gyroscope sensor at a sampling frequency, and transmit the representations received at the sampling frequency as a respective vibration signal associated with sampling times. The signal processor is coupled to the multiple mobile devices. The signal processor generates a processed upsampled signal by interleaving the vibration signal received from each mobile device and processing the interleaved signal using one or more machine learning filters, and transmitting the processed upsampled signal.

    Abstract: A medical lead includes a lead body, an electrical connector, an electrical conductor, and a sleeve. The lead body includes a distal end and a proximal end defining a longitudinal axis of the lead body. The electrical connector is positioned near the proximal end of the lead body. The electrical conductor extends about the longitudinal axis of the lead body. The sleeve is coupled to an insulative material of the lead body and positioned around the electrical conductor. The electrical conductor is electrically coupled to the electrical connector. The sleeve is not fixed to the electrical conductor. In response to bending of the medical lead, the conductor may move within the sleeve to relieve strain created by the bending.
