Patent number: 11937037Abstract: A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.Type: GrantFiled: May 27, 2022Date of Patent: March 19, 2024Assignee: Apple Inc.Inventors: Zachary C. Rich, Kurt R. Stiehl, Arun D. Chawan, Michael B.

Patent number: 11592377Abstract: A sensor for measuring the fatigue life of a structure subjected to repetitive loads is disclosed. The sensor includes a backing material arranged for securement to the structure, and a foil arranged for securement to the backing material. The foil includes a conductive path along which electrical current flows at an initial resistance measured prior to the structure being subjected to repetitive loads. A crack initiation feature in the form of a notch is located on the conductive path. In response to repetitive loads applied to the structure, one or more cracks propagate from the crack initiation feature across the conductive path to cause electrical resistance to increase whereby the progression of fatiguing of the structure may be determined.Type: GrantFiled: April 20, 2020Date of Patent: February 28, 2023Assignee: Vishay Measurements Group, Inc.Inventors: Thomas P. Kieffer, James I. Hardy, Robert B. Watson

Patent number: 9797789Abstract: An electrical resistance strain gage includes a uniformly distributed electrical resistance of the active measuring area and a discrete electrical trim resistance within an active measuring are. The trim resistance may include an electrical conductor in an electrically parallel circuit such that the electrical conductor may be selectively electrically removed from the strain gage to trim the electrical resistance of the strain gage. The trim resistance does not modify the active strain sensing area or uniform grid length.Type: GrantFiled: January 3, 2014Date of Patent: October 24, 2017Assignee: Vishay Measurements Group, Inc.Inventors: Robert B. Watson, Thomas P. Kieffer, Rebecca L. Showalter

Patent number: 8161829Abstract: A methodology for selecting and properly placing foil strain gages on a transducer in a Wheatstone bridge, which provides a more consistent creep response, especially when the transducer temperature is changed. A transducer includes a counterforce subjected to a predetermined physical load that provides tension and compression strains (positive and negative, respectively). The transducer also includes a plurality of strain gage grids that are operatively attached to the counterforce in the tension and compression strain areas of the counterforce and generate electrical signals. The plurality of strain gages are electrically connected in a Wheatstone bridge circuit where their electrical signals due to creep are cancelled.Type: GrantFiled: July 28, 2010Date of Patent: April 24, 2012Assignee: Vishay Precision Group, Inc.Inventors: Felix Zandman, Robert B. Watson, Thomas P. Kieffer
