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: 10422947Abstract: The rolled photonic fibers presents two codependent, technologically exploitable features for light and color manipulation: regularity on the nanoscale that is superposed with microscale cylindrical symmetry, resulting in wavelength selective scattering of light in a wide range of directions. The bio-inspired photonic fibers combine the spectral filtering capabilities and color brilliance of a planar Bragg stack compounded with a large angular scattering range introduced by the microscale curvature, which also decreases the strong directional chromaticity variation usually associated with flat multilayer reflectors. Transparent and elastic synthetic materials equip the multilayer interference fibers with high reflectance that is dynamically tuned by longitudinal mechanical strain. A two-fold elongation of the elastic fibers results in a shift of reflection peak center wavelength of over 200 nm.Type: GrantFiled: October 19, 2018Date of Patent: September 24, 2019Assignees: President and Fellows of Harvard College, University of ExeterInventors: Joanna Aizenberg, Mathias Kolle, Peter Vukusic, Robert D.

Patent number: 7255192Abstract: A self-actuating robot or vehicle tether capable of moving itself, remaining free while traversing around obstacles, and free itself is disclosed. In a preferred embodiment of the invention, a valve is mounted to the tether or robot. An inflow conduit attached to or in the tether is connected to the valve. A fluid flows through the tether and the valve is opened and closed to create a waterhammer effect in the inflow conduit. The forces created on the tether from the waterhammer effect result in motion of the tether and in freeing of the tether from obstructions. Closing and opening the valve further creates pressure changes in the tether, thereby causing momentary dimensional changes in the tether. In an alternative embodiment, a plurality of valves are placed along the tether. Pulsing of the plurality of valves while a fluid flows through the tether results in the tether effectively moving itself.Type: GrantFiled: October 26, 2004Date of Patent: August 14, 2007Assignee: President and Fellows of Harvard CollegeInventors: Douglas P.

Patent number: 5983727Abstract: An improved fluid pressure sensor/sensor array is shown to provide high resolution, sensitivity which can be easily controlled based on anticipated or detected pressure range, and reliable pressure measurements with easy installation and low fabrication cost. A fluid pressure sensor is provided having a substantially incompressible mounting structure with a cavity formed therein. An elastic membrane is attached to said mounting structure and across said cavity, separating the cavity from the fluid to be measured. At least one non-contact transducer is attached to the mounting structure in the cavity to detect deflection at a selected plurality of regions on the membrane. The sensitivity and pressure range of the sensor can be chosen by preselecting the elasticity of the membrane, stretching the membrane across the cavity under a preselected tension, maintaining a predetermined reference pressure in the cavity, and/or actively controlling the membrane tension.Type: GrantFiled: August 19, 1997Date of Patent: November 16, 1999Assignee: Pressure Profile SystemsInventors: Parris S. Wellman, Jae S. Son, Robert D. Howe

Patent number: 4865443Abstract: This invention comprises an optical displacement sensor that uses the inverse-square attenuation of light reflected from a diffused surface to calculate the distance from the sensor to the reflecting surface. Light emerging from an optical fiber or the like is directed onto the surface whose distance is to be measured. The intensity I of reflected light is angle dependent, but within a sufficiently small solid angle it falls off as the inverse square of the distance from the surface.At least a pair of optical detectors are mounted to detect the reflected light within the small solid angle, their ends being at different distances R and R+.DELTA.R from the surface.Type: GrantFiled: June 10, 1987Date of Patent: September 12, 1989Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Robert D.
