Document	Document Title
US11446062B2	Vector compression system The present disclosure describes surgical anchors and related devices and methods that can be used for surgical bone fracture fixation. Some implementations use a polymeric cored braided suture held in place by anchors on each side of a fracture. In some implementations, the anchors are secured into bone while maintaining high tension (e.g., relative to certain prior art methods) in the suture during the deployment process. Some implementations provide for tensioning (e.g., using a polymeric cored braided suture) to compress the fracture and hold the bone in place, functioning as though the suture has sewn the bone (e.g., fragments or portions) together. This can, for example, provide rigid fixation of a fracture which may be important for healing to occur. The tension preload can provide compression to maintain fixation in the face of tensile and shear loads applied to the bone (e.g., as a result of movement and weight bearing).

The bias voltage generator is coupled to an output terminal of the output stage circuit to generate a bias voltage according to an output voltage of the output terminal. The first amplifier circuit is coupled to the output terminal, a first power supply terminal and the bias voltage generator, receives a first pre-driving signal, a first predetermined voltage and the bias voltage, and determines whether to transmit a first voltage to serve as the output voltage. The second amplifier circuit is coupled to the output terminal, a second power supply terminal and the bias voltage generator, receives a second pre-driving signal, a second predetermined voltage and the bias voltage, and determines whether to transmit a second voltage to serve as the output voltage.
US11451195B2	Amplifying apparatus An amplifying apparatus includes a transistor arranged on a substrate and constituting an amplifier, an input terminal for inputting a high-frequency signal to the amplifier, an output terminal for outputting the high-frequency signal amplified by the amplifier, a first inductor formed in or on the substrate and connected between a source of the transistor and a ground, and a second inductor formed in or on the substrate and connected between a gate of the transistor and the input terminal. When the substrate is viewed in a plan view, the first inductor and the second inductor do not overlap each other. The first inductor and the second inductor are magnetically coupled to each other.
US11451191B1	Systems and methods for solar forecasting The present disclosure provides a method for controlling a solar power plant comprising a plurality of solar modules. The method may comprise (a) obtaining irradiance data at a first time and a second time from a plurality of sensors disposed among or adjacent to the plurality of solar modules; (b) processing the irradiance data at the first time and the second time to generate an output that indicates whether one or more solar modules of the plurality of solar modules will be covered by a shadow or shade at a third time; (c) generating, based at least in part on the output, a power output prediction for the plurality of solar modules at the third time; and (d) adjusting a power output of the solar power plant based at least in part on the power output prediction.
US11451186B2	Power generation source and distribution system A renewable-energy electrical generation and distribution system including a first container and a second container. Each of the first container and the second container includes a power source disposed within the container and deployable therefrom, and generating energy from a renewable resource. A first compartment is disposed within the container, and retains a battery in communication with the power source. A power distribution system is disposed within the container and in communication with the battery and with the power source. A communications system is disposed within the container and configured to communicate data via an ad-hoc mobile communications network formed by the first container and the second container and configured to operate independent of any communication network not part of the first container and the second container forming the ad-hoc mobile communications network.
US11451185B2	Battery pack, power tool and battery pack charger system When providing alternating current (AC) power to operate AC powered devices such as power tools (such as drills, table saws, miter saws), equipment (such as lawn mowers), and consumer products (such as refrigerators, television, lights) without being tied to a fixed utility power supply typically requires a generator (such as an internal combustion engine based generator) or a battery powered inverter. In order to meet power and runtime needs for these devices, a battery powered inverter must be relatively large and expensive. This simple fact prohibits their use in many environments.
