摘要： A light driver having a primary side driver configured to convert an input from a mains power supply to a primary side output, and a secondary side driver coupled to the primary side driver and configured to rectify and filter the primary side output to provide a driver output current for driving a light load. A microcontroller controls the light driver at start-up so that the secondary side driver is powered-on and the primary side driver is in a non-powered state during a soft-start period, and subsequent to the soft-start period the secondary side driver is set to be in a low output state when powered-on and thereafter set to a state so that driver output current of the secondary side driver increases the light output from the light load from an initial dim level to a nominal dim level without flicker.

摘要： A system for implementing mains-voltage-based dimming of a solid state lighting module includes a transformer, a mains sensing circuit and a processing circuit. The transformer includes a primary side connected to a primary side circuit and a secondary side connected to a secondary side circuit, the primary and second side circuits being separated by an isolation barrier. The mains sensing circuit receives a rectified mains voltage from the primary side circuit and generates a mains sense signal indicating amplitude of the rectified mains voltage. The processing circuit receives the mains sense signal from the mains sensing circuit across the isolation barrier, and outputs a dimming reference signal to the secondary side circuit in response to the mains sense signal. Light output by the solid state lighting module, connected to the secondary side circuit, is adjusted in response to the dimming reference signal output by the processing circuit.

摘要： During a financial technique, electronic devices may exchange, using a first communication technique, information with each other to establish a secure connection between the electronic devices when they are proximate to each other. After the secure connection is established, the electronic devices may hand off communication with each other from the first communication technique to a second communication technique that supports communication at a higher data rate and over longer distances than the first communication technique. Moreover, the electronic devices may communicate, using the second communication technique and the secure connection, additional information associated with the financial transaction with each other to facilitate completion of the financial transaction.

摘要： Mobile payments and processing data related to electronic transactions. A near field communication connection is established between a mobile communication device of a consumer that serves as a mobile wallet and an electronic payment device of a merchant. Authorization data is shared between the mobile communication device and the electronic payment device without providing electronic payment instrument (e.g. credit card) data to the merchant. Authorization data is transmitted from the mobile communication device to a cloud computer or resource that serves as a cloud wallet and hosts respective data of respective electronic payment instruments of respective consumers, and from the electronic payment device a payment processor computer. The payment processor computer presents the authorization data to the cloud wallet, and in response, the cloud wallet transmits the credit card data to the payment processor computer, which processes the transaction.

摘要： A user registers with an automated transportation use and billing system. The user's geographical location/position is monitored and periodically compared with the geographical location/position of one or more public transportation systems. When a determination is made that the user's geographical location/position is the same as the geographical location/position of a public transportation system, an assumption is made that the user is making use of the public transportation system and once the user's geographical location/position data differs from the public transportation system's geographical location/position data, it is further assumed that the user is no longer making use of the public transportation system. Data indicating the users assumed use of the public transportation system, calculated as described above, is then recorded and credited to the user's account.
