摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Disclosed herein are systems and methods using power line communication to control light fixtures. The system operates in two phases. In the first phase, a control device generates commands which are encoded on a control signal. The control signal is generated by encoding data using two sinusoidal waves, the second sinusoidal wave being a phase-shifted copy of the first sinusoidal wave. The resulting control signal is sent on a power line. The control signal is received by light fixtures and/or sensors through an ultra-narrow band filter, decoded and converted to executable instructions for the light fixtures and data parameters for sensors. In the second phase, the light fixtures are jointly controlled by the control device and the sensors. The control in phase two is hybrid open loop/closed loop control.

摘要： 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.

摘要： 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.
