  • Publication number: 20220132389
    Abstract: A method of operating a mesh network is disclosed (FIG. 6). The method includes receiving a data frame (600) having a header with plural addresses (FIG. 1) and determining that the data frame is not from an access point or a leaf node (602) of the mesh network. A next recipient address of the plural addresses is removed (610) when the next recipient is a final destination. The next recipient address is set (612) when the next recipient of the data frame is not a final destination. The data frame is transmitted (614) to the next recipient.

  • Patent number: 10750573
    Abstract: A BLE network includes a first piconet including a first master scanner and a first group of low-power slave/advertisers for transmitting wireless advertisements. Circuitry in the first master/scanner wirelessly scans to detect an advertisement transmitted by a first slave/advertiser of the first group and transmits a connection request in response to the detecting, and transmits a schedule for subsequent advertisements after an initial advertisement by the first slave/advertiser. Circuitry in the first slave/advertiser transmits the initial advertisement, receives an acceptance a resulting connection request, establishes association with the first master scanner, and then causes the first slave/advertiser to go to sleep, to wake up and transmit subsequent advertisements according to the schedule and accept resulting connection requests, and transmits available data to the first master/scanner, and goes back to sleep.

  • Publication number: 20160329183
    Abstract: The present disclosure provides a power switch for use in a power management system including a power source for supplying an electrical current, and a load for receiving the electric current upon establishing a circuit with the power source. The power switch includes a motion sensor, a timer, and a gate. The motion sensor is configured to sense a motion related to an operation of the load and generate an idle signal when the sensed motion is below a predetermined threshold. The timer is coupled with the motion sensor, and it is configured to activate a power-off signal upon detecting the idle signal for a predetermined time period. The gate is coupled with the timer, and it is configured to either complete the circuit when the power-off signal is inactive or break up the circuit when the power-off signal is active.

  • Patent number: 7634226
    Abstract: A method is provided for propagating data among multiple locations in an area. The method includes using a plurality of transponders distributed throughout the area, each able to receive, store, and transmit data. The method further includes using scanners moving relative to the transponders, and able to transfer data to and from these transponders over a wide or limited range. When a scanner encounters a transponder (becomes close enough for data communication), it reads data from the transponder and writes data to the transponder, including data read from prior encounters with other transponders. Data written to a transponder by a scanner may include data associated with that scanner, including but not limited to one or more of identification, speed, direction, and time stamp. The method thus propagates data among transponders and makes this transponder data available to scanners as they encounter these transponders.

  • Publication number: 20080143840
    Abstract: Deblurring digital camera images captured in low-light, long-integration-time conditions by capturing multiple short-integration images and fusing with on-the-fly motion estimation and alignment to limit the frame memory requirements. In one embodiment, an image stabilization system includes: (1) a frame memory and (2) a processor coupled to the frame memory and configured to store a first short-integration digital image in the frame memory, determine a displacement of a second short-integration digital image relative to the first short-integration digital image, combine the second short-integration digital image with the first short-integration digital image to form a fused digital image and overwrite the first short-integration digital image with the fused digital image.

  • Publication number: 20070263605
    Abstract: A system comprising a first communication device and a second communication device which transmits a text-based message to the first communication device. The message comprises an internet protocol (IP) address associated with the second communication device. If VoIP telephony is possible between the first and second communication devices, the first communication device automatically extracts the IP address from the message and uses the IP address to automatically establish a voice over Internet protocol (VoIP) call with the second communication device.
