  • Publication number: 20250006478
    Abstract: A controller for a generator includes a feedforward control module. The feedforward control module is configured to generate an adjustment profile to control a parameter of a generator in accordance with a desired output signal. The feedforward control module generates a plurality of adjustment values in accordance with sub-regions of the output signal. Each sub-region includes a portion of the desired output signal.

  • Patent number: 11369449
    Abstract: A surgical robot can be configured for minimally invasive surgery (MIS) and other types of surgery with modular link geometry and disposable components. In some examples, the surgical robot includes a cable driver comprising at least one drive motor configured for tensioning a cable. The surgical robot includes an articulated surgical tool coupled to the drive motor by the cable. The articulated surgical tool comprises at least first and second articulated links and a joint coupling the first and second articulated links. The cable passes through the joint, and the joint comprises an elastic antagonist biased in opposition to tension from the cable to allow bidirectional actuation of the joint. The surgical robot includes a safety lock configured to lock the joint from allowing articulation of the first and second articulated links in response to a loss of tension in the cable.

  • Patent number: 10821542
    Abstract: A radio frequency (RF) power delivery system includes a first RF generator and a second RF generator. The first RF generator operates as a master RF generator, and the second RF generator operates as a slave RF generator. The slave RF generator includes a detector for sensing an electrical characteristic of the RF signal of the slave RF generator. The slave RF generator also includes a detector for sensing an electrical characteristic of the RF signal from the master RF generator. Operation of the slave RF generator is controlled by a host or controller. The host or controller operates the slave RF generator in accordance with electrical properties determined by the second detector.

  • Patent number: 9482179
    Abstract: A multi-layer cylinder head gasket is provided. The cylinder head gasket includes a plurality of layers of material, each of the layers has a plurality of openings including at least one cylinder bore opening and at least one pushrod opening. Each of the layers has an edge which surrounds the at least one pushrod opening, and the pushrod openings of the layers are aligned axially with one another. An eyelet extends axially in each of the pushrod openings and covers the edges of the layers for protecting a pushrod extending through the respective pushrod opening. The eyelet is made of a material that is softer than the material of the plurality of layers.

  • Patent number: 9041480
    Abstract: A radio frequency (RF) generation system includes an impedance determination module that receives an RF voltage and an RF current. The impedance determination module further determines an RF generator impedance based on the RF voltage and the RF current. The RF generation system also includes a control module that determines a plurality of electrical values based on the RF generator impedance. The matching module further matches an impedance of a load based on the RF generator impedance and the plurality of electrical components. The matching module also determines a 2 port transfer function based on the plurality of electrical values. The RF generation system also includes a virtual sensor module that estimates a load voltage, a load current, and a load impedance based on the RF voltage, the RF generator, the RF generator impedance, and the 2 port transfer function.
