Abstract: Systems and methods are provided for detecting and analyzing changes in a body. A system includes an electric field generator, an external sensor device, a quadrature demodulator, and a controller. The electric field generator is configured to generate an electric field that associates with a body. The external sensor device sends information to the electric field generator and is configured to detect a physical change in the body in the electric field, where the physical change causes a frequency change of the electric field. The quadrature demodulator receives the electric field from the electric field generator and is configured to detect the frequency change of the electric field and to produce a detected response. The controller, coupled to the electric field generator, is configured to output a frequency control signal to the electric field generator and to modify the frequency of the electric field by adjusting the frequency control signal.

Abstract: Disclosed is an improved implementation of a flood fill mesh network that utilizes probability forwarding for rebroadcasting network messages. The forwarding probability may be determined based on analyzing a network topology map constructed by each network node relative to its neighbor nodes communicating on the network and derived from state information contained in synchronization frames broadcasted by the network nodes on the network. The forwarding probability may comprise a statistical probability that a message frame received by a network node will be forwarded to the intended destination network node by one or more of the network node's neighbor network nodes.

Abstract: Disclosed is an improved implementation of a flood fill mesh network that utilizes low power and does not require any network addressing or routing protocol for network message delivery. Network messages are only communicated to a network node's correspondents using broadcast network messages over a wireless network. Network messages propagate throughout the network based on each correspondent node rebroadcasting received messages to its correspondent nodes, and so on. Coordinated synchronization across network nodes can be achieved by each network node broadcasting synchronization frames to its correspondents within a synchronization window time period and thereafter adjusting its own start time for the next synchronization period to converge synchronization. A guard band may also be utilized to account for any clock drift and signal path delays between any two communicating network nodes.

Abstract: Disclosed is an improved implementation of a flood fill mesh radio network that utilizes message age disambiguation to prevent unnecessary propagation of repeated messages in the network. A digital counter may be used to generate a sequence of numbers based on counter values and the counter values may be associated with each message frame that is broadcast into the mesh network. The domain of generated sequence numbers can be divided up into low and high subdomains and the maximum number of message frames broadcast by a network node in the mesh network may be constrained so that no two messages broadcast by a network node remain circulating in the network longer than that required for the digital counter to wrap back to zero. Under this paradigm the counter values associated with each message can be compared to determine the relative age of the message frames to detect repeated messages.

Abstract: Disclosed is an improved implementation of a flood fill mesh radio network that utilizes probability forwarding for rebroadcasting network messages. The forwarding probability may be determined based on analyzing a neighbor topology map constructed by each network node relative to its neighbor nodes on the network and derived from state information supplied in synchronization frames. The forwarding probability may comprise a statistical probability that a message frame received by a network node will be forwarded to the intended destination network node by one or more of the network node's neighbor network nodes. The forwarding probability may also be based on constructing a heat map of hot nodes that are identified as those originating nodes in originating node/forwarding node pairs that are the first to forward message frames along paths in the network relative to duplicate message frames received from different originating/forwarding node pairs along different paths.

Abstract: Methods and systems for monitoring the well-being of a target are disclosed. In a method embodiment, data representing a signal is received by a computer system. The signal may be generated at least in part by one or more sensors in response to the detection of a change in an electrical field, electric potential, capacitance, and/or dielectric constant of a target spaced apart from the one or more sensors. The method may further include identifying, using the computer system and based at least in part on the data electronically received by the computer system, a recurring pattern in the received data. The method may also include determining, using the computer system and based at least in part on the received data, whether a deviation from the recurring pattern transgresses a threshold. The deviation may comprise a subset of the data electronically received by the computer system.

Abstract: Apparatuses, methods, and systems for tracking movements of golf clubs and alerting a golfer when one or more golf clubs are misplaced from a group of golf clubs. A peripheral unit is associated with and affixed to each of a number of golf clubs, and transmits signals that are detected and collectively processed by a base unit to determine the status of those clubs. A club may be designated as misplaced based on the sequence and timing of status events, upon which an alarm is activated to alert the golfer. Also the base unit may process signals regarding movement of golf clubs in conjunction with location data from a Global Positioning System device to obtain information regarding the user's golf performance.
