  • Patent number: 10804790
    Abstract: In some examples, a controller is configured to control a primary-side switch in a power converter circuit, and the controller includes a first node configured to receive a first signal indicating a current or a voltage through a primary side of a transformer of the power converter circuit. The controller also includes a second node configured to receive a second signal indicating a current or a voltage through a primary-side switch of the power converter circuit. The controller further includes processing circuitry configured to determine a target value for the second signal based on the first signal and generate the control signal for the primary-side switch based on the target value for the second signal.

  • Patent number: 9979299
    Abstract: In one example, a method includes activating, by a controller of a power converter, a switch of the power converter that controls an amount of energy provided by the power converter; receiving, by an input of the controller, a signal that represents an amount of current flowing through the switch; responsive to determining that the amount of current flowing through the switch is greater than or equal to a threshold amount of current, deactivating, by the controller, the switch; and responsive to determining that an amount of time elapsed since activation of the switch is greater than a threshold amount of time, deactivating, by the controller, the switch.

  • Publication number: 20140170922
    Abstract: Fibers that are formed from a thermoplastic composition that contains a polymer and high surface area nanostructures are provided. The fibers have a voided structure and low density while maintaining good strength characteristics. To achieve such a structure, a blowing agent in the thermoplastic composition is activated during extrusion to form bubbles in the fibers. The high surface area nanostructures in the formed fibers can be formed of or carry the blowing agent and can enhance the strength of the fibers and compensate for the non-load bearing voids of the fibers.

  • Patent number: 7171166
    Abstract: A wireless, programmable system for bio-potential signal acquisition (e.g., electrocardiogram (ECG) data) includes a base unit and a plurality of individual wireless, remotely programmable transceivers that connect to patch electrodes. The base unit manages the transceivers by issuing registration, configuration, data acquisition, and transmission commands using wireless techniques. Bio-potential signals from the wireless transceivers are demultiplexed and supplied via a standard interface to a conventional monitor for display.

  • Patent number: 6533729
    Abstract: A blood pressure sensor includes a source of photo-radiation, such as an array of laser diodes. The sensor also includes a two-dimensional, flexible reflective surface. The reflective surface is nominally positioned relative to the radiation source such that the radiation travels in a direction normal to the reflective surface. The reflective surface is placed adjacent to the location on the patient where the blood pressure data is to be acquired. Radiation from the source is reflected off of the reflective surface onto a two-dimensional array of photo-detectors. Systolic and diastolic blood pressure fluctuations in the patient are translated into deflections of the patient's skin. These deflections cause corresponding deflections in the two dimensional reflective surface. The associated movement of said flexible reflective surface due to blood pulsation causes scattering patterns from said reflective surface to be detected by the two dimensional array of photo-detectors.
