Patent number: 11444805Abstract: A method of transmitting a block from a bridge to a mesh network includes transmitting the block to at least a first node of a plurality of nodes, for distribution through the mesh network. The block includes a plurality of packets. The bridge receives, from the plurality of nodes, a plurality of status packets. Each status packet indicates reception status of the plurality of packets at a respective node of the plurality of nodes. The bridge selects at least a first packet of the plurality of packets for retransmission to the mesh network, based on the status packets. The bridge generates a retransmission block including at least the first packet. The first packet is included in the retransmission block a number of times based on the status packets.

Patent number: 9729687Abstract: Wearable communication devices, e.g. implemented in a watch, using short range communication e.g. to a cell phone allow a user to talk and listen, place and answer calls, send and receive text messages, initiate voice commands to mobile search for information and find locations, and be notified of incoming calls, texts, and events, all while a phone is nearby but not visible. Notification is performed with vibration, an LED light or OLED text display of incoming calls, texts, and calendar events. It allows communicating hands-free. The watches can be directly connected to a smartphone allowing using the watch as “remote control” for home appliances or any other devices via voice and buttons. Motion sensors such as accelerometer, magnetometer and gyroscope, together with audio generation device can be used for gaming applications.Type: GrantFiled: August 12, 2013Date of Patent: August 8, 2017Assignee: SilverPlus, Inc.Inventors: Jeffrey Hsieh, Dennis Kwan, Suresh Singamsetty, Stanley Kinsey

Patent number: 8937554Abstract: A personal monitoring and communication system includes a monitoring and communication control device, at least one personal monitoring communication device coupled with a person and a personal monitoring communication device finder. The personal monitoring communication device includes a GPS receiver, cellular telephone circuits, and short-range wireless radio circuits for communicating with caregivers. The personal monitoring communication device finder receives an emergency beacon generated by one personal monitoring communication device and determines a location of the personal monitoring communication device. A dead reckoning circuit determines the position of the person from a reference location. A motion detection circuit determines that the person is moving, not moving, or has fallen. A battery power management circuit minimizes power consumption to increase battery life of a battery powering the personal monitoring communication device.Type: GrantFiled: September 28, 2011Date of Patent: January 20, 2015Assignee: SilverPlus, Inc.Inventors: Dennis Kwan, Suresh Singamsetty, Jeffrey Hsieh

Publication number: 20140161274Abstract: This disclosure provides a wired and wireless headphone device and method which supports the selective attachment to an audio source of one or more additional wireless headphones. The elements include a base headphone, an audio gateway device with transceiver, antenna controls, a battery, an audio connector for attachment to an audio source. In wireless mode, the base headphone operates as a single headphone. In audio gateway mode, the base headphone operates as a wired headphone and as an audio gateway for one or more additional wireless headphones receiving the same audio source as the base headphone. The key advantages of this device and method are the elimination of a standalone audio gateway box and ability to add more wireless headphones using dynamic audio coding selection.Type: ApplicationFiled: December 10, 2013Publication date: June 12, 2014Applicant: SilverPlus, Inc.Inventors: Suresh Singamsetty, Dennis Kwan, Jefferson Hu, Jeffrey Hsieh

Patent number: 8614963Abstract: A communication system that allows communication devices to synchronize the transfer of data to allow the devices to wirelessly and efficiently communicate in a star or mesh network. The communication system operates in the presence of other communication systems noise sources using a spread spectrum frequency hopping transmission scheme to efficiently generate adaptive frequency hopping patterns that are unique to the members of the wireless network based on a network identification code. The communication system employs a predictive retrieval of data for transmission from one device storing the data to a requesting device. A communication device transfers communication from a first network to a second network when the device has been moved beyond the range of the first network, where the second network is in communication with at least one other member device of the first network.Type: GrantFiled: April 25, 2011Date of Patent: December 24, 2013Assignee: SilverPlus, Inc.Inventors: Suresh Singamsetty, Dennis Kwan, Jeffrey Hsieh

Patent number: 8594346Abstract: A driver circuit for a piezoelectric speaker is described, wherein charge is transferred from a charge reservoir to the speaker. In a first embodiment a delta sigma circuit uses a pulse width modulated digital audio signal to control a push-pull circuit to drive the piezoelectric speaker. High frequency harmonics are introduced to the delta sigma drive signals to enhance the low frequency response of the speaker. A charge recovery mechanism recovers charge from the speaker to reduce the frequency of replenishing the charge reservoir and to provide additional drive current for the speaker. In a second embodiment the pulse width modulated signal is used to drive a voltage quadrupling circuit that drives the piezoelectric speaker, wherein the reservoir capacitor is integrated with the capacitors of quadrupling circuit, which provides charge recovery.Type: GrantFiled: June 13, 2011Date of Patent: November 26, 2013Assignee: SilverPlus, Inc.Inventors: Dennis Kwan, Suresh Singamsetty, Jeffrey Hsieh
