Abstract:
The disclosure relates to a transmission scheme for nodes in a network. More specifically, the disclosure relates to an acknowledgment scheme that minimizes energy requirements for an acknowledgment of a transmission between nodes. The disclosure describes that an energy constrained node may transmit to other nodes in a network and may only require that an acknowledgment of that transmission is received from at least one of the proximal recipients, which may or may not be the ultimate target. In order to minimize the complexity of the receiver in a node and its energy requirements, the acknowledgment scheme may employ simple on-off keying (OOK) irrespective of the modulation technique of the sending transmission. The acknowledgment comprises a series of OOK pulses sent at a specified time after receipt of the transmission. In addition, simultaneously received acknowledgments can be processed and verified without confusion.
Abstract:
The disclosed subject matter may provide a system and methods for commissioning a device or appliance into a network. A processor may detect the insertion of a removable device into a data receptacle of a first device. The first device may be an appliance or a network controller. Information may be retrieved from or delivered to the removable device. The information may be information specific to the appliance, such as model number, or may be information related to the network controller. For example, information delivered from the network controller to the removable device may include a network address assignment and network protocol to be used by an appliance when the appliance communicates with the network. The removable device may be removed from the first device and inserted into a data receptacle of a second device.

Abstract:
Multiple devices may be simultaneously programmed using JTAG circuitry or a JTAG operation. The output of a master device's programming may be used to verify the programming of one or more slave devices. The comparison of the master device's programming output to a slave device's programming output may be handled by a logic circuit. The logic circuit may signal the result of the comparison by, for example, a LED.
Abstract:
Systems and techniques are provided for transmitting a light towards a plurality of acousto-optic retro reflectors, arranged as an array, that are configured to physically react to an acoustic signal. The physical reaction modulates the transmitted light which is reflected back towards a light detector and analyzed. The analysis may include detecting an acoustic signal source location and/or reconstructing the acoustic signal. A light scanner may be configured to transmit the light towards the plurality of acousto-optic retro reflectors in a predetermined, continuance, or dynamically determined sequence.

Abstract:
Disclosed is a memory device in which the state of the memory may be set by a mechanical action, with or without mains power present. The memory state may be detected by a microcontroller. The state for the memory device may be reset by a microcontroller. The microcontroller may be external to an apparatus containing the memory device, adjacent to or within the apparatus.
