A fuel pump having a unique cellular telephone calling number operable in response to receiving a cellular message. The pump includes a cellular phone component and may include a SIM card slot and SIM card. A number of pumps may each be equipped with a cellular phone component each having a unique calling number and a cellular phone system provider configured to authorize sending of information representing a pre-authorized amount of fuel to be dispensed as a wireless cellular signal to one or any of the pumps. A method of selling fuel includes sending a cellular telephone signal to a unique telephone number associated with the fuel pump and assessing a charge to the cellular telephone of a user prior to authorizing the sending of the signal.
摘要:
A polarization mode dispersion compensator that includes two stages, one for reducing or eliminating first order polarization mode dispersion of an optical signal, and second stage for reducing or eliminating higher order polarization mode dispersion of the optical signal. In each stage, the polarization is adjusted so as to reduce polarization mode dispersion. Based on the power levels of various polarization states generated at the second polarization controller, the optical signal to noise ratio may be estimated. Furthermore, based on the amount of adjustment used to control the polarization controllers and the differential group delay, the polarization mode dispersion may be estimated.

A collating conveyor (4, 6) receives products (2) sequentially from a delivery point and collates them into groups (8). A pusher (9) transfers groups (8) of products from the collating conveyor (4, 6) to a receiving trough (10), where they are turned through a predetermined angle B. The collating conveyor (4, 6) is inclined to the horizontal and is provided with lugs (5, 7), each of which supports a stack (8) of products under the effect of gravity. A pick-and-place head (11) picks up a group (8) of products from the trough (10) by gripping and clamping the products (2) together.

摘要:
A system and method for processing a request by a first control service using a first control specification language, and a second control service using a second control specification language includes steps of: receiving the request from a requestor; providing the request to the first and second control services; receiving a decision on the request from each of the first and second control services; and comparing the decisions. The first control specification language is an access control policy.

An electric lock for remote access control to a container wherein a U-shaped latch is mounted on a door in alignment with a slot in a housing mounted in the container. Upon closure, the latch enters the housing to engage a slotted keeper therein and causes rotation of the keeper. Rotation of the keeper causes a release lever to engage a stepped protrusion on the keeper and secures the keeper and latch. Activation of a solenoid or drive motor coupled to the release lever permits withdrawal of the latch from the housing. The axes of rotation of the keeper and release lever are located to greatly reduce the impact of pre-release forces to the door.
摘要:
A feedforward controller for controlling the polarization state of an optical signal. The feedforward controller includes an optical input for receiving an optical input signal having an input polarization state, an optical output for transmitting an optical output signal having an output polarization state, a polarization controller coupled to the optical input and the optical output, and a transfer function determiner for determining a characteristic polarization transfer function of the feedforward controller from the input and output polarization states. The polarization controller is adapted to modify the polarization state of light passing therethrough in dependence on the characteristic polarization transfer function of the feedforward controller.
摘要:
A printhead is provided which has a plurality of types of printheads modules. Each type of module is determined by its geometric shape in plan so that the combination of the determined module types forms the printhead to extend and print across a pagewidth. At least one row of printhead nozzles defined across the determined types of modules includes at least one displaced row portion.
