A device for facilitating financial account transactions is described which includes a processing unit including a cryptographic processor. The device also includes an input unit, a display unit and a memory device connected to the processing unit. The memory device contains a private cryptographic key, a first data element and a second data element. The processing unit encrypts the first data element using the private cryptographic key and the second data element, modifies the second data element, combines the encrypted first data element and the second data element to generate a single-use financial account identifier, and displays the single-use financial account identifier. This identifier is then transmitted to a central processor for authorization of the transaction. The central processor extracts and decrypts data elements from the transmitted identifier using the private cryptographic key, compares those data elements with data elements stored in a memory, and verifies the single-use financial account identifier in accordance with the comparison.

A method for controlling the cranking of an engine of a vehicle powertrain system having a rechargeable energy storage system that is adapted to provide electric power to an electric machine, wherein the system is adapted to exit from the engine crank state as a function of an output voltage of the energy storage system to the electric machine during the crank state, if the output voltage is less than a crank undervoltage threshold for a predetermined crank time. According to the method, the crank undervoltage threshold is a function of the number of failed start attempts, generally decreasing as a function of the number of failed start attempts. The predetermined crank time is a function of a magnitude of a difference between the output voltage and the crank undervoltage threshold.

An antenna end is formed at an upper portion of the post for installing antenna parts, and a support end is formed at a lower portion of the post for fixing the antenna device to the ground. At least part of an external body of the antenna end is formed of a material that transmits transmission and received radio signals and a ground support member is formed under the support end to make an external body of the support end stand erect on the ground. The external appearance of the antenna device may take the form of a conventional utility, lamp, or sign post or pole.

Security systems typically communicate with alarm monitoring centers using a telephone connection. Security systems will check in with the alarm monitoring center with a diagnostic signal at a predetermined interval—typically once per day. When a security system is connected to a Voice-over-IP service (using Broadband Internet), rather than a standard telephone line, the opportunity exists to poll in real-time the status of the connection, and alert the owner (or alert the alarm monitoring center) that the customer's connection has been broken. The present invention offers a system and technique for monitoring a security system connected using a Voice-over-IP connection, in real time, and alerting the owner of the security system, or the alarm-monitoring center, when the connection is broken. This alert can be used, for example, to issue a telephone call to the police, informing them of the breach of line integrity and possible compromise of the premise.
