  • Publication number: 20180078153
    Abstract: An apparatus includes one or more memories storing computer readable code and processor(s). The processor(s), in response to loading and executing the computer readable code, cause the apparatus to perform operations including receiving electrocardiogram data from an electrocardiogram sensor. The electrocardiogram data includes data from an electrocardiogram from a person. The operations also include receiving pulse wave data from one or more pulse wave pressure sensors. The pulse wave data includes data from one or more pulse waves from the person. The operations further include determining blood pressure using the electrocardiogram data or the pulse wave data from the chest and the pulse wave data from the wrist or finger, and outputting an indication of the blood pressure. Another apparatus uses pulse wave data from two pulse wave sensors (e.g., pulse wave pressure sensor(s) and/or PPG sensor(s)) and blood pressure determinations are made using these pulse wave data.

  • Publication number: 20170095166
    Abstract: An apparatus includes a wearable sensor structure that includes multiple individual sensor units placed in a row. Each individual sensor unit includes a first portion to contact a surface of skin under which arteries and/or veins are to be located, and a second portion that contacts the first portion and is configured to have a capacitance. The first and second portions are configured to create a capacitance change in response to a squeezing or bending between the first portion and a fixed part of the second portion caused by a pulse pressure and release of the pulse pressure. The apparatus includes circuitry configured to measure waveforms for the individual sensor units. Each waveform captures the capacitance change for its corresponding individual sensor unit. The apparatus includes a wireless interface configured to transmit the waveforms. A computing system is also disclosed that analyzes the waveforms and can provide alerts based thereon.

  • Patent number: 9393633
    Abstract: A method and apparatus for making chip assemblies is disclosed that prevent or reduce the cracking and delamination of ultra low-k dielectrics in the back-end-of-line in Si chips that can occur during the chip assembly process. The method and apparatus apply pressure to the top and bottom surfaces of a substrate during the chip bonding process so that the bending and warping of the assembled modules are reduced. The reduced bending and warping prevent or reduce the cracking and delamination of ultra low-k dielectrics.

  • Patent number: 9219035
    Abstract: Methods of forming an integrated circuit device include forming an interlayer dielectric layer on a first surface of a semiconductor substrate and then forming an interconnect hole that extends through the interlayer dielectric layer and into the semiconductor substrate. A first sidewall spacer layer is formed on a sidewall of the interconnect hole. The semiconductor substrate at a bottom of the interconnect hole is isotropically etched to define an undercut recess in the semiconductor substrate. This etching step is performed using the first sidewall spacer layer as an etching mask. The interconnect hole and the uncut recess are then filled with a through-via electrode. A second surface of the semiconductor substrate is removed for a sufficient duration to expose the uncut recess containing the through-via electrode.

  • Patent number: 9181947
    Abstract: A compressor is provided in which a rotary member suspended on a stationary member is rotated to compress a refrigerant. As the rotary member is suspended on a first stationary member and rotatably supported on a second stationary member spaced apart from the first stationary member, components can be easily centered and assembled with structural stability. In addition, oil stored in a hermetic container is supplied to a lubrication passage provided between the rotary member and the stationary member. This reduces friction loss between the components and achieves operational reliability. Moreover, the oil is easily introduced into a vane mounting hole in which a vane is linearly reciprocated. This reduces friction and abrasion of the vane and improves the operational reliability.
