Biological measurement systems and methods are described. In one embodiment, a biological function monitoring system includes a first monitoring device, including a first sensor, a first processor, and a first transmitter. The first sensor senses a first biological function measurement during monitoring a biological function and derives a first data symbol representing the first biological function measurement. The first processor accesses the first data symbol from the first sensor, and combines two or more chaotic waveforms from a first chaotic waveform ensemble, generating a first composite chaotic waveform. The first transmitter transmits the first composite chaotic waveform to a receiver over a communication channel. The biological function monitoring system may include a second monitoring device that is similar to the first monitoring device. The second monitoring device generates a second composite chaotic waveform and transmits the second composite chaotic waveform to the receiver over the communication channel.

Biological measurement systems and methods

Systems and methods for integrated communication security are described. One aspect includes a clock generator configured to generate a clock signal at a first frequency, and a circuit utilizing the clock signal. The circuit may include a port configured to receive an encryption sequence at the first frequency, and a first unidirectional data path between the port and a memory configured to permit data transfer from the port to the memory. The memory may be configured to access the encryption sequence from the port via the first unidirectional data path and store the data. The circuit may further include a clock divider configured to divide the first frequency by a divisor deriving another clock signal at a second frequency, and an encryption/decryption module configured to read a portion of the encryption sequence from the memory, process input using the portion of the encryption sequence, and generate output responsive to the processing.

Integrated communication security

Example routing systems and methods are described. In one implementation, a first set of routing systems is interfaced with a network connection via a network interface. A second set of routing systems interfaced with a secure system is configured to receive information from the first set of routing systems via a first unidirectional data channel. In some embodiments, the first set of routing systems is configured to receive information from the second set of routing systems via a second unidirectional data channel. The secure system is not visible from the network interface.

Routing systems and methods

Example inventory management and monitoring systems are described. In one implementation, an inventory management system includes a computing system that receives multiple images captured by multiple imaging devices wirelessly coupled to the computing system. The computing system also receives a spatial location of each imaging device as determined by a device positioning system. The computing system is configured to determine a spatial location of an object in each of the multiple images and monitor the objects in the images to determine changes in the location of the objects.

Inventory management and monitoring

Example communication systems and methods are described. In one implementation, a method receives a first chaotic sequence of a first temporal length, and a second chaotic sequence of a second temporal length. The method also receives a data symbol for communication to a destination. Based on the data symbol, the second chaotic sequence is temporally shifted and combined with the first chaotic sequence to generate a composite chaotic sequence. The first chaotic sequence functions as a reference chaotic sequence while the second chaotic sequence functions as a data-carrying auxiliary chaotic sequence.

Communication using chaotic waveforms

Example routing systems and methods are disclosed. In one realization, a first routing system and a second routing system are disposed within a vehicle. A computing system disposed within the vehicle is configured to communicate with a remote computing system via a network interface, with the first routing system being coupled to the network interface, the second routing system being coupled to the computing system, and the first routing system and second routing system being coupled via two independent, uncoupled, unidirectional data channels.

Example routing systems and methods are described. In one implementation, an apparatus includes a network interface, a secure system, and a routing system disposed between the network interface and the secure system. The routing system communicates with the network interface along a first data transmission channel and communicates with the secure system along a second data transmission channel. The secure system is not visible from the network interface. The routing system accesses data in the secure system and communicates the data to the network interface.

Communication systems and methods

Example chaotic communication systems and methods are described. In one implementation, a method receives a portion of a chaotic waveform that has a temporal length. The method also receives a data signal for communication to a destination. A chaotic data signal is generated based on the received data signal. The chaotic data signal includes the chaotic waveform inserted at periodic intervals based on the temporal length of the chaotic waveform.

Chaotic communication systems and methods

A system, processing structure and method for performing vehicle intercept includes target acceleration estimation or blocking via a filter prior to deriving an interceptor acceleration time history via a guidance law. In the processing structure where the unknown target accelerations are blocked from affecting estimates, a guidance law is generated, stored and retrieved accounting for worst case target acceleration. In the processing structure where the target acceleration is presumed constant with a constant bank angle, the guidance law is closed form, exploiting constant heading angular velocity, and thus generated online.
