Patent number: 11958734Abstract: The invention concerns a bottle opener (101) for removing a cap (301) from a bottle (300). It comprises an image sensor (206) for capturing an image of the cap (301), a fulcrum surface (103) for contacting the cap and a hook (102,104) engageable under a flange (304) of the cap (301) for removing it from the bottle in response of a relative rotation of said bottle opener (101) with respect to the bottle (300) using the fulcrum surface (103) as a fulcrum. A removal detector (202, 204) is arranged to trigger a capture of an image by sensing a force between the fulcrum surface (103) and the hook (104) that exceeds a predefined threshold.Type: GrantFiled: June 12, 2018Date of Patent: April 16, 2024Assignee: WeCheer SAInventors: Karim Choueiri, Khoi Quc Anh Luong, Aurèle De Bosset, Minh Ly, Tai Le Tan Huynh

Patent number: 11210172Abstract: An information handling system includes a processor complex and a baseboard management controller (BMC). The processor complex provides boot status information in response to a system boot process of the processor complex. The BMC receives first boot status information from the processor complex in response to a first system boot process, compares the first boot status information to baseline status information to determine first boot status difference information, compares the first boot status difference information to baseline boot status difference information to determine that the information handling system experienced an anomaly during the first system boot process, and sends an alert that indicates that the first system boot process experienced the anomaly.Type: GrantFiled: March 19, 2020Date of Patent: December 28, 2021Assignee: Dell Products L.P.Inventors: Timothy M. Lambert, Andrew Butcher, Anh Luong

Patent number: 10833725Abstract: A method of providing wireless communications in a wireless network can include wirelessly receiving a chirp spread-spectrum modulated signal at a first gateway device, the chirp spread-spectrum modulated signal being transmitted by a remote client device. The chirp spread-spectrum modulated signal can be demodulated at the first gateway device to provide demodulated data at the first gateway device. The demodulated data can be processed to provide an indication that a decode of a packet including the demodulated data failed. Time adjacent chirps included in the demodulated data can be combined to provide combined data at the first gateway device. A message can be transmitted from the first gateway device to a remote server responsive to an amplitude of the combined data exceeding a threshold value and the indication that the decode of the packet including the demodulated data failed.Type: GrantFiled: June 2, 2020Date of Patent: November 10, 2020Assignee: Carnegie Mellon UniversityInventors: Adwait Dongare, Artur Balanuta, Akshay Gadre, Robert Iannucci, Swarun Kumar, Anh Luong, Revathy Narayanan, Anthony Rowe

Patent number: 9154241Abstract: A test system for testing a wireless electronic device is provided. The test system may include a test host and a tester. The test host may instruct the electronic device under test (DUT) to transmit radio-frequency test signals in a selected resource block of a desired channel identified by a channel number in the Long Term Evolution frequency band. The tester may measure harmonic output power levels of the radio-frequency test signals transmitted by the DUT at harmonic frequencies of the selected resource block. The test host may compare the measured harmonic output power levels to threshold power levels to characterize the radio-frequency performance of wireless circuitry in the DUT. The test system may test the radio-frequency performance of the DUT for radio-frequency test signals transmitted by the DUT in some or all resource blocks in the desired Long Term Evolution band.Type: GrantFiled: November 13, 2012Date of Patent: October 6, 2015Assignee: Apple Inc.Inventors: Anh Luong, Aristoteles D.

Patent number: 8983395Abstract: Wireless communications circuitry such as radio-frequency power amplifiers may be tested using a test station. A test station may include a test host and a test unit coupled to the test host. The power amplifiers may be configured to transmit radio-frequency signals in allocated resource blocks within a particular radio channel. The power amplifier circuits may be configured to transmit signals utilizing only an allocated portion of its total available resource blocks so that the transmitted signals are output at maximum power levels. The power amplifiers may transmit in resource blocks near a low channel edge during a first time period and may transmit in resource blocks near a high channel edge during a second time period. The test unit may receive the signals generated from the power amplifiers and may perform desired radio-frequency measurements (e.g., test unit may measure adjacent channel leakage radio, signal-to-interference ratio, error vector magnitude, etc.).Type: GrantFiled: December 12, 2011Date of Patent: March 17, 2015Assignee: Apple Inc.Inventors: Anh Luong, Daniel C.

Patent number: 8831529Abstract: A test system for calibrating wireless electronic devices is provided. The test system may include a test host, a radio communication tester, and a temperature chamber in which an electronic device under test (DUT) may be tested. The DUT may include a temperature sensor for monitoring an internal temperature of the DUT and may include power amplifier circuitry for outputting radio-frequency test signals. The tester may be used to measure output power levels of the radio-frequency test signals when the DUT is operating at a given reference temperature and when the DUT is operating at target operating temperature levels other than the given reference temperature. Power amplifier output level offset compensation values may be computed by comparing output power levels measured at each of the target operating temperatures to output power levels measured at the given reference temperature and may be stored in the DUT prior to normal operation.Type: GrantFiled: April 30, 2012Date of Patent: September 9, 2014Assignee: Apple Inc.Inventors: Yuping Toh, Anh Luong

Patent number: 8811192Abstract: An electronic device may include wireless circuitry such as cellular telephone transceiver circuitry and wireless local area network (WLAN) transceiver circuitry. The telephone transceiver may be used to establish long-range wireless connectivity, whereas the WLAN transceiver may be used to establish short-range wireless connectivity. The performance of the WLAN transceiver may suffer in the presence of heat-generating operations. The performance of the WLAN transceiver may be tested using test equipment while the electronic device is configured in a test mode and a normal user mode. During testing, the WLAN transceiver may be directed to transmit radio-frequency signals while the telephone transceiver is toggled on and off. The test equipment may be used to analyze the radio-frequency signals to measure the transmit power level, transmitter constellation error, transmit spectrum mask, and other performance parameters to determine whether that device under test satisfies design criteria.Type: GrantFiled: February 10, 2011Date of Patent: August 19, 2014Assignee: Apple Inc.Inventor: Anh Luong

Patent number: 8731493Abstract: A system for performing wireless local area network testing of wireless devices may include a wireless local area network tester and a device under test. The tester and device under test may communicate over a wireless link. To ensure that the tester accurately analyzes test data, a data rate table is used that specifies fixed data transmission rates to be used by the device under test under both high-quality link conditions and low-quality link conditions. This forces the device under test to transmit control packets at the same high data rate during packet loopback testing, regardless of link quality. When the captured control packets are analyzed at the tester, both low-link-quality data and high-link-quality data may be analyzed using a common test template, ensuring accurate results.Type: GrantFiled: October 27, 2010Date of Patent: May 20, 2014Assignee: Apple Inc.Inventors: Anh Luong, Justin Gregg
