Patent number: 12003911Abstract: A first earbud configured to communicate with a user media device and a second earbud. The first earbud includes a battery, a battery monitor configured to determine a power level of the battery, a mode controller. The mode controller is configured to receive a first power level value from the battery monitor and a second power level value from the second earbud and make a determination that the first earbud is operating in a primary mode in which the first earbud receives audio data from the user media device and transmits the received audio data to the second earbud. The mode controller is further configured, in response to the determination that the first earbud is operating in the primary mode, switch the first earbud from the primary mode to a secondary mode based on at least one of the first power level and the second power level.Type: GrantFiled: November 18, 2021Date of Patent: June 4, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: John S.

Patent number: 11921179Abstract: Methods, computing devices, and magnetic resonance imaging systems that improve image quality in turbo spiral echo (TSE) imaging are disclosed. With this technology, a TSE pulse sequence is generated that includes a series of radio frequency (RF) refocusing pulses to produce a corresponding series of nuclear magnetic resonance (NMR) spin echo signals. A gradient waveform including a plurality of segments is generated. The plurality of segments collectively comprise a spiral ring retraced in-out trajectory. During an interval adjacent to each of the series of RF refocusing pulses, a first gradient pulse is generated according to the gradient waveform. The first gradient pulses encode the NMR spin echo signals. An image is then constructed from digitized samples of the NMR spin echo signals obtained based at least in part on the encoding.Type: GrantFiled: April 28, 2022Date of Patent: March 5, 2024Inventors: Zhixing Wang, Steven P.

Patent number: 7457544Abstract: A group delay compensation equalizer is disclosed that employs a single channel four-port WDM device for compensating the group delay experienced by a plurality of wavelengths transmitted over different paths. The transmission differential between two wavelengths is compensated by transmitting the two wavelengths through two different paths where the fiber length in reflecting the second wavelength is equal to the transmission time difference between the two wavelengths. The single channel four-port group delay equalizer effectively provides a unidirectional signal flow, as compared to the conventional equalizer that transmits optical signals bi-directionally. The present invention reduces the cost of a group delay equalizer by simplifying the use of multiple three-port WDM devices into a single channel four-port WDM device.Type: GrantFiled: November 16, 2004Date of Patent: November 25, 2008Assignee: Avanex CorporationInventors: John Feng, Xuehua Wu, Sanjai Parthasarathi, Giovanni Bararossa

Patent number: 7340130Abstract: The present invention describes a structure and method for a multi-ports WDM device for compensating the filter distortion while reducing insertion loss. The multi-ports WDM device comprises a 4-fiber collimator having a grin lens and a 2-fiber collimator having a lens where the focal plane of the second lens is shorter than the focal plane of the first grin lens Ands with aspheric surface. When a light signal travels through the first lens in the 4-fiber collimator to a filter, the film on the filter causes distortion to the light signal resulting in a large insertion loss. To compensate for the insertion loss, the lens on the 2-fiber collimator has a aspheric function and a shorter focal plane than the grin lens on the 4-fiber collimator. The type of grin lens used in the 4-fiber collimator is different than the lens used in the 2-fiber collimator. Effectively, the lens in the 2-fiber collimator operates to de-focus a light signal relative to the grin lens in the 4-fiber collimator.Type: GrantFiled: October 11, 2005Date of Patent: March 4, 2008Assignee: Avanex CorporationInventors: Xuehua Wu, Mingjun Zhao, John Feng
