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: 4972566Abstract: A glass container inspection machine includes a head assembly, a console, and a cable connecting the two. The head assembly includes a measuring oscillator and a reference oscillator the outputs of which are applied to a Phase Detector Multiplier. A fixed resistance in the output circuit of the measuring oscillator is selected so that the output of the Phase Detector Multiplier is the same no matter what the frequency of the oscillation. The oscillation and the Phase Detector Multiplier are part of a Phase Locked Loop, the amplifier portions of which are in the console. The machine is comprised of four such data channels, each of which includes a head assembly operating at a different oscillator frequency. All components that are frequency dependent are included in the head assembly while all components in the console are frequency independent. Thus the output of any of the head assemblies may be connected via the cable to any of the data channels of the console.Type: GrantFiled: April 24, 1990Date of Patent: November 27, 1990Assignee: Emhart Industries, Inc.Inventors: Robert P. Andersen, Paul F. Scott, Edward F. Vozenilek

Patent number: 4723977Abstract: Method and apparatus for electronically controlling a servo motor drive for glass gob distribution apparatus, to provide accurate high speed motion of one or more scoops. At the set-up stage, the operator adjusts the scoop position with respect to each trough to align scoop and trough in a straight line. During automatic operation, upon receipt of a MOVE command a motion control computer provides digital output signals to move the scoops through a prescribed motion profile, such profile having suitable characteristics to move the scoops over various distances without vibration or overshoot. A digitalized cubic-parabolic-cubic (CPC) curve or similar cam profile is scaled to the amplitude and direction of the required motion, and the motion profile computer outputs command signals on a point-by-point basis over the time span of this stored motion profile. Such time span is designed to provide sufficient dwell time to allow the gobs to traverse the scoops.Type: GrantFiled: November 19, 1986Date of Patent: February 9, 1988Assignee: Emhart Industries, Inc.Inventors: Marty J. Grant, George T. Peterson, Robert P. Andersen

Patent number: 4687502Abstract: A gob distributor for directing glass gobs to glassware-forming sections. Most particularly, this relates to the automatic positioning of scoops receiving the glass gobs from the glassmaking apparatus and directing them into troughs of glassware-forming sections which are arranged in a bank. The gob distributor features an arrangement wherein the distributor may be converted to vary the number of scoops in a scoop group from one to three or more. Principal features of the gob distributor are the utilization of a servomotor which is a reversible DC motor for positioning a rack which controls the angle of the scoops, and a releasable ball screw drive.Type: GrantFiled: July 8, 1986Date of Patent: August 18, 1987Assignee: Emhart Industries, Inc.Inventors: Robert J. Douglas, Robert L. Doughty, John P. Mungovan, Robert P. Andersen, Vaughan Abbott

Patent number: 4551163Abstract: A glass feeder plunger operating mechanism driven by an electric motor controlled by a programmable computer programmed to drive the motor in a predetermined manner in order to generate a predetermined motion profile of one or more glass feeder plungers. The plungers are secured to the end of a cantilevered lateral support bracket which is cyclically and vertically reciprocated by cyclical oscillations of the electric motor. The output shaft of the motor is connected to a ball screw in threaded engagement with a ball nut which is secured to a member connected to the plunger support bracket. The plunger support bracket is attached to a moveable vertical support shaft which maintains plunger alignment during the range of motion. The operating mechanism is attached to a frame which is adjustable in two dimensions to facilitate alignment of the plungers with their respective orifices. Air cylinders are provided to counter-balance the weight of the members being vertically reciprocated.Type: GrantFiled: June 4, 1984Date of Patent: November 5, 1985Assignee: Emhart Industries, Inc.Inventors: Robert J. Duga, Constantine W. Kulig, Robert L. Doughty, Robert J. Douglas, Robert P. Andersen

Patent number: 4223676Abstract: Apparatus for the surgical removal of tissue is disclosed comprising a handpiece having a resonant vibrator with a magnetostrictive stack and connecting body encompassing a hollow elongated tool which is ultrasonically vibrated at its tip longitudinally to a peak to peak stroke of at least 0.005 inches at about 25,000 cps (25 KHz). A generator powers the vibrator and is automatically controlled at the frequency to maintain the resonant vibration. Aspiration is provided by suction through the hollow tool at its tip, and a manifold enclosing the tool end of the handpiece provides irrigation.Type: GrantFiled: December 19, 1977Date of Patent: September 23, 1980Assignee: Cavitron CorporationInventors: David G. Wuchinich, Alan Broadwin, Robert P. Andersen
