Patent number: 9509143Abstract: A wide dynamic range charger module is configured to couple a variable power source such as a photovoltaic cell to a load. The module determines a maximum power point (MPPT) of the power source and based at least in part upon that MPPT selects one of a plurality of power converters to provide power to the load. The selection is such that the selected power converter is operating within its operating regime. The selected power converter may further be configured to a pre-determined input admittance which corresponds to the power source.Type: GrantFiled: March 16, 2015Date of Patent: November 29, 2016Assignee: Amazon Technologies, Inc.Inventor: David C.

Patent number: 9477306Abstract: Substrates for components such as a display, touch sensor, multifunction stackup, and so forth may incorporate one or more haptic actuators configured to generate haptic output. These actuators may be formed from a portion of a body of the substrate, or separate pieces bonded or otherwise affixed to the substrate. Audible output resulting from activation of the actuators may be minimized by coupling the actuators such that they produce a physical displacement of the body of the substrate within, rather than orthogonal to, the plane of the body of the substrate.Type: GrantFiled: December 16, 2010Date of Patent: October 25, 2016Assignee: Amazon Technologies, Inc.Inventors: Joseph J.

Patent number: 9148190Abstract: In some implementations, an electronic device includes an actuator having a coil and a magnet, at least one of which may be movable relative to the other. The coil may receive a drive current to cause movement of at least one of the magnet or the coil, such as to provide a haptic output, motivate a loudspeaker, or the like. A transceiver electrically coupled with the coil through a connection circuit may use the coil as an antenna for at least one of sending or receiving a radio frequency communication through the coil. Additionally, or alternatively, the coil may be placed into proximity to a source of a magnetic field to induce an electric current in the coil. The induced electric current may be passed from the coil to a power management system, such as to charge a battery or the like.Type: GrantFiled: January 17, 2012Date of Patent: September 29, 2015Assignee: Amazon Technologies, Inc.Inventors: David C.

Patent number: 9131623Abstract: Devices and methods for constructing low-profile, minimal-thickness electronic devices using existing production techniques are disclosed in this application. An electronic component and interposer form a sub-assembly. The sub-assembly is placed in an aperture in a circuit board with the interposer providing interconnections between the electronic component and the circuit board. The circuit board is coupled to the electronic component at least by one or more fluidic channels included in the interposer.

Patent number: 9030308Abstract: User interface experiences with electronic devices are enhanced with feedback cues such as haptic or vibrotactile output feedback. One or more piezoelectric actuators generate haptic output. The one or more piezoelectric actuators may be integrated onto a display substrate, a battery case, a device enclosure, or other component. Such integration may improve propagation of the haptic output to the user, reduce bulk of the electronic device, minimize parts count, and reduce production costs.Type: GrantFiled: July 2, 2010Date of Patent: May 12, 2015Assignee: Amazon Technologies, Inc.Inventors: David C. Buuck, Joseph J. Hebenstreit

Patent number: 9019720Abstract: Components within a portable device are arranged around a perimeter of a display component to reduce the height of the portable device. Components such as a battery, a main logic board, a wireless networking interface, and so forth may be distributed around a display component such as an electrophoretic display. Distribution of components around the perimeter of the display component rather than behind the display component reduces the height. Furthermore, the placement of components in the perimeter provides a structure for a user to grip the portable device or for placement of user actuable controls.Type: GrantFiled: November 12, 2012Date of Patent: April 28, 2015Assignee: Amazon Technologies, Inc.Inventors: David C.
