Abstract: Disclosed is a system and method for more secure card transactions. The security is generated by the use of a dynamic transaction number which is valid for only a single predetermined time interval. The transaction number is generated through a two step process. In a first step, time is used as an input to a transaction number function. The transaction number function outputs a plurality of digits. The second step uses the plurality digits for input and uses a ruleset to strip at least one digit to determine the transaction number valid for the predetermined time interval.

Abstract: Disclosed is a system and method for transmitting more data on the same bandwidth as current wireless and wired schemes use. A method for transmitting data can use orthogonal frequency domain multiplexing by identifying a lowest frequency subcarrier in an orthogonal frequency division multiplexing bandwidth that includes 64 subcarriers. The method can include receiving the second, fourth, eighth, sixteenth, thirty-second, and sixty-fourth subcarriers using a bandpass filter and decoding the set of orthogonal functions for each of the second, fourth, eighth, sixteenth, thirty-second, and sixty-fourth subcarriers. The method can further include combining the decoded data to recover the transmitted data.

Abstract: Disclosed is an Internet of Things system for allowing hub to device and device to device communication on the system. The system is built on a backbone of physical power lines and primarily relies on a power line communication protocol for sending messages between the hub and the devices or between devices. Each of the devices on the system, regardless of function is built on foundational architecture which guarantees that the device will be able to communicate on the system. A smart device, operating in conjunction with a universal device acts as the hub of the system.

Abstract: Disclosed is a method for creating one or more passwords, each in compliance with website or file requirements, from a single password containing only letters. Several parameters, including the total number of characters, any type of required character, including capital letters, digits, and special characters, and the number of each type of required character are entered in to a cipher algorithm. The cipher algorithm creates a set of possible characters from the letters of the alphabet, digits, and any special characters. According to the ruleset for the character position, the available characters from the set are made available for assignment for a predetermined period, and assigned by keystroke.

Abstract: Disclosed is a system and method for power line control of electrical fans. The system generates a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by routing the wave through a phase inversion circuit a predetermined intervals according to a protocol. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for controlling a fan motor.

Abstract: Disclosed is a method for communication between two devices or between an application and the device on which the application is running. The method uses a text or natural language based syntax in the creation of a library of text language elements. An approval computing device can approve the associations of the library. The library may be transmitted to a second computing device with a message. The text language elements are converted to computer executable code by a text language module or text language application running on the device.

Abstract: Disclosed is a system and method for a smart hydroponic system. The system includes a central controller and one or more smart hydroponic system modules. The smart hydroponic system modules automate a number of tasks required to maintain hydroponic agriculture. Further, these tasks are localized to provide greater precision to the agriculture, as even indoor environments can vary. The central controller sends commands which affect every smart hydroponic system module. This provides an efficient mix of central and local control.

Abstract: Disclosed is a system and method for increased security of files stored on local machines. The system and method include a number of checks to ensure that the file is being opened on the local machine where it was created. The checks may include a comparison to a CPUID of the machine on which the file is being opened to a CPUID stored in a script when the file was created. The checks may also include a review of a plurality of memory locations in search of artifacts indicating that the file is being opened on a virtual machine. A server may also check that any messages send from the local machine do not pass through an intermediate server.

Abstract: Disclosed is a system and method for more secure card transactions. The security is generated by the use of a dynamic transaction number which is valid for only a single predetermined time interval. The transaction number is generated through a two step process. In a first step, time is used as an input to a transaction number function. The transaction number function outputs more than 16 digits. The second step uses the more than 16 digits for input and uses a ruleset to strip at least one digit to determine the transaction number valid for the predetermined time interval.

Abstract: Disclosed is a smart home system for controlling peripheral devices. The smart home system allows a single computing device to control a plurality of peripheral devices. The system can include a crystal oscillator. The computing device connects to a universal device. The universal device connects to one or more system modules. The universal device and system modules communicate using a protocol stored, at least in part, on both the universal device and system modules. The use of the protocol and the system module to peripheral device interface allows for a universality of peripheral devices. That is, the smart home system allows for the extension of smart control to non-traditional smart devices.

Abstract: Disclosed is a sensor and method for detecting one or more gasses in a sample. The sensor includes two sample tube sections, which allow for a larger sample, and correspondingly, more accurate measurement. Having two sample tube sections increases the total length of the sample path. However, placing the sample tube sections in parallel allows for the performance of the sensor to be enhanced, but the footprint of the sensor to remain unchanged. Light pipe material may be used to transport the light between sample tube sections. Further, light pipe material may be used to move the IR lamp away from the first filter tube section, reducing problems in the thermopile by dissipating heat from the IR lamp away from the sample tube section.

Abstract: Disclosed is a sensor for detecting the proximity of smart devices previously connected to the sensor using the IEEE 802.11 protocols. Importantly, the sensor does not operate using a Bluetooth® connection, which would require the smart devices previously connected to the sensor using the IEEE 802.11 protocols to also have Bluetooth® protocols enabled. Enabling such Bluetooth® protocols uses more battery than having the IEEE 802.11 protocol adapter enabled. The sensor references a list of previously connected smart devices and attempts to connect with any in range, if none can be connected to, the sensor emits an audible alarm signal. Further, no application is required for the sensor to operate.

Abstract: Disclosed is an air filter and a method of manufacture for an air filter which is much more cost effective and provides greater operational effectiveness than state-of-the-art air filters. The air filter includes an outer metallic shell which may be used to attach the filter in line to ducting of a heating, ventilation, and air conditioning (HVAC) system. The filter may further include a filter unit made of activated carbon material. The filter unit may have one or more sections and may have a honeycomb cross section.

Abstract: Disclosed is a system and method for power line control of devices. The system operates in two modes. In mode one, the system operates on an open loop architecture with a controller generating a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by alternating the output of two phase shifted waves which have the same frequency and amplitude to form a control signal. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for the devices and data parameters for sensors. In mode two, the system operates on a hybrid open loop/closed loop architecture where devices are jointly controlled by the controller and the sensors.
