    Abstract: A mobile power system may include a bidirectional AC-DC converter configured to convert a grid AC signal to a power limited DC charging signal with a threshold level, a battery module configured to provide a DC power signal, and a controller coupled to the battery module and the bidirectional AC-DC converter and configured to selectively switch the bidirectional AC-DC converter between a first state and a second state. The first state may include, when a load power level is less than the threshold level, concurrently charging the battery module using the power limited DC charging signal and delivering the grid AC signal to a load. The second state may include, when the load power level is greater than the threshold level, concurrently converting the DC power signal with the bidirectional AC-DC converter into a battery AC signal for delivery to the load, and delivering the grid AC signal to the load.

  • Publication number: 20220105651
    Abstract: A food slicer assembly includes a housing defining a first opening and a second opening perpendicularly arranged. A slicing blade received at the second opening enters the first opening of the housing. A coupling releasably couples a food product or a food product packaging to the housing. The first opening receives a food product therethrough, the second opening receives the slicing blade therethrough, and the slicing blade slices the food product arranged in the first opening such that the food product is divided into multiple portions using the food slicer assembly. The slicing blade may pass into the first opening from a first end, and upon reaching the second end, the slicing blade seals the food slicer assembly at the first opening. The assembly may be a cheese slicer assembly for slicing a block of cheese so that a slice of cheese can be removed from the first opening.

  • Publication number: 20220104740
    Abstract: A hemodialysis patient data acquisition and management system resides on a host computer which receives information from one or more non-invasive, optical blood monitors associated with a hemodialysis system. When a patient is undergoing hemodialysis treatment, a sensor assembly monitors the patient's blood flowing through the hemodialysis system and a controller for the blood monitor generates data which includes at least an identification code for the patient undergoing the treatment on the respective system, and non-invasively determined blood data taken at the onset of the scheduled treatment, such as initial Hgb, HCT, and SAT values. A host computer communicates with the one or more optical blood monitors, preferably via a wireless network, and the patient's session commencement data is downloaded to the host computer.

  • Publication number: 20220109247
    Abstract: This document describes techniques and apparatuses for a plastic air-waveguide antenna with conductive particles. The described antenna includes an antenna body made from a resin embedded with conductive particles, a surface of the antenna body that includes a resin layer with no or fewer conductive particles, and a waveguide structure. The waveguide structure can be made from a portion of the surface on which the embedded conductive particles are exposed. The waveguide structure can be molded as part of the antenna body or cut into the antenna body using a laser, which also exposes the conductive particles. If the waveguide is molded as part of the antenna body, the conductive particles can be exposed by an etching process or by using the laser. In this way, the described apparatuses and techniques can reduce weight, improve gain and phase control, improve high-temperature performance, and avoid at least some vapor-deposition plating operations.
