Publication number: 20190109919Abstract: Devices are equipped with BLE modules that can scan, advertise, or both scan and advertise to form smart devices with beaconing capabilities. A cloud server can act as a bridge to allow a first user to remotely communicate with a second user based on the beacon generated by the smart devices. The cloud server, based on the beacon generated, can send commands to initiate one or more processes, such as to send reminders, to send open commands, or to send a digital key. Alternatively, the cloud server can act as a bridge between the first user and the second user based on the second user scanning and decoding a QR code using an app running on a smartphone used by the second user.Type: ApplicationFiled: December 4, 2018Publication date: April 11, 2019Inventor: Hoang Nhu

Patent number: 9980082Abstract: Systems, components, and methods for tracking, monitoring, and optionally reminding for use with hospitals, businesses, and office buildings. The components of the systems can include wearable advertising devices (WAD) that emit BLE signals, repeaters and/or gateways for receiving and relaying the BLE signals over a BLE Mesh network to a remote server. IR codes can be included to detect the presence of a WAD before the WAD is energized to emit a BLE signal.Type: GrantFiled: February 16, 2016Date of Patent: May 22, 2018Assignee: KOOLTECHS INC.Inventor: Hoang Nhu

Patent number: 9959242Abstract: Communication accessories, such as keyfobs (KFs) and/or transmitter/receiver dongles, which can transmit and receive signals to enable connectivity between owners of different portable devices even when the devices are off or when in a sleep mode, are described. In some examples, the keyfobs and/or the dongles are programmed with connectivity tokens, such as being programmed with Facebook (FB) information, FB accounts or FBIDs, LinkedIn ID, or generically social network user information, that can be used to authenticate different smart portable devices belonging to different users to facilitate networking. Once the keyfobs and/or dongles are authenticated, they will buzz, sound, or otherwise alert their respective owners that one or more social network users, such as a FB user or a LinkedIn user, are within the general vicinity and that further actions through smart portable devices may be needed to connect the users.Type: GrantFiled: May 7, 2013Date of Patent: May 1, 2018Assignee: Hoang NhuInventor: Hoang Nhu

Publication number: 20110211658Abstract: A system and method are disclosed for performing digital multi-channel decoding of a BTSC composite audio signal. Each subsequent stage of the digital multi-channel decoding process is performed at the lowest sampling rate that yields acceptable performance for that stage. Analog-to-digital conversion of the composite audio signal is performed first to generate a composite digital audio signal. After analog-to-digital conversion, all signal processing may be performed in the digital domain. The composite digital audio signal is digitally filtered to frequency compensate for variations caused by previous stages of processing, including IF demodulation. Digital channel demodulation and filtering are performed to isolate single channels of the composite digital audio signal such as SAP, L?R, and L+R channels.Type: ApplicationFiled: March 22, 2011Publication date: September 1, 2011Inventors: David Chaohua Wu, Hoang Nhu, Russ Lambert, Alexander G.

Patent number: 8005667Abstract: Methods and systems for sample rate conversion convert a sampled signal to a higher data rate signal. Conversion pulses are received, having a conversion rate that is higher than the sample rate of the sampled signal. Sample points are then reconstructed from the sampled signal, in real time, on either side of a conversion pulse. An interpolation is performed between the reconstructed sample points, at the time of the conversion pulse. The interpolation results are outputted in real time. The process is repeated for additional conversion pulses. The outputted interpolated amplitudes form the higher data rate signal having a data rate equal to the conversion rate. Sample rate conversion is thus performed in real time according to the higher data rate clock, rather than with fixed ratios. As a result, when the higher data rate clock is affected by, for example, jitter or other frequency variations, the higher data rate samples immediately track the lower data rate samples.Type: GrantFiled: August 4, 2008Date of Patent: August 23, 2011Assignee: Broadcom CorporationInventor: Hoang Nhu

Patent number: 7457420Abstract: A Japanese BTSC audio broadcast signal has three modes of transmission: mono, stereo, or dual mono. The control channel centering at 3.5 fH is one of the three channels in the J-BTSC signal, and contains information to indicate to the decoder which one of the three modes the audio transmission is in. The present invention uses a bandpass filter directly in the AM band, followed by envelope filtering and a decision circuit. Therefore, the need for AM demodulation and AM carrier detection is eliminated.Type: GrantFiled: August 15, 2003Date of Patent: November 25, 2008Assignee: Broadcom CorporationInventor: Hoang Nhu
