A file transfer application maintains a secure connection over the Internet with a file transfer gateway. A user selects a file and the file transfer application requests a unique ticket from the gateway. The ticket is stored in both the gateway and the file transfer application. Next, the ticket is then encoded in a URL that can be sent to potential recipients of the file via conventional methods. Upon entering the URL into a web browser, the recipient will navigate to the file transfer gateway. The gateway decodes the URL to recover the ticket and looks up the ticket in the database to determine the associated application instance and file description. The gateway will then request the application instance to start encrypting and streaming the contents of the file identified by the ticket to the gateway, which then retransmits the encrypted stream to the recipient's web browser.

A system and method for postage payment utilizes passive RFID tags as postage “stamps”, with the amount of the postage automatically billed to a previously-established customer account. The tags are stored in a separate stamp database and are “enabled” by linking the individual tag to a customer account.

The existence of a customer account with a proper return address reduces the likelihood of a dead letter. Also, a special category of stamps may be used for automatic reply mail. By virtue of using an RFID tag, the mailed item's progress through the postal delivery system may be tracked from dispatch to delivery.

A tool driver activates a telemetry tool when a predetermined threshold of accelerometer data measured by an accelerometer. The threshold preferably corresponds to an acceleration level expected while drilling mud is pumped at a slow pump rate through the well's drill pipe. When a fluid influx occurs during drilling, the well is shut-in, and the tool driver turns off the telemetry tool. The drill pipe and casing pressures of the shut-in well are obtained.

A signalling mechanism in an OFDMA-based wireless communication system in which the number of bits used to indicate the 2-D resource allocation in each frame are reduced, and optimised for the particular frame configuration. The numbers of bits within the MAP-IEs in at least the DL_MAP and optionally also the UL_MAP of each frame, used to represent the Symbol offset and No. of Symbols, are scaled to the frame duration and the subcarrier allocation scheme used for the zone to which the DL-MAP_IE is associated. Likewise, a variable number of bits is used for the subchannel offset and number of subchannels, which can be optimised based on the selected FFT size and subcarrier allocation scheme. The bit numbers in use can be TLV encoded and transmitted within a downlink channel descriptor following the DL_MAP and UL_MAP. Therefore, in subsequent frames each subscriber station knows the number of bits being used to represent these parameters, and thus the field sizes in the MAP_IEs, until such time as the DCD is updated. In this way, the signalling overhead incurred by the MAP_IEs, which can be very significant for a large number of users and with some frame and FFT sizes, is reduced.

Teachings herein include a base station for propagating system information changes from the base station to the relay node. Upon transmitting system information changes to the relay node, the base station defers data transmission between the base station and the relay node until a set time period. In many embodiments, the base station is configured to actually apply the system information changes during this time period, while the relay node applies the changes before then, e.g., by applying them immediately upon reception. The base station's deferral of data transmission until the set time period thus ensures that data transmission does not occur until both the base station and the relay node have applied the pending changes. This in turn prevents radio link failure from occurring due to use of different system parameters by the base station and relay node.

A metallic ring is made of two metals, wherein one metal forms a major arcuate portion and the other a minor arcuate portion of the ring, thereby forming a thermocouple-type structure as a result of the two inter-metallic junctions. The metallic ring supports a surface plasmon whose energy is matched to the energy, i.e. wavelength, of an incident light beam so that the oscillating electromagnetic field of the light resonates with the plasmon.

The system comprises: a plurality of portable access keys, each being provided to one of the users and having an associated variable access parameter; an access barrier, having an open state allowing passage through and a closed state denying access to the resource, and defining an access queue; a sensor that determines an access queue characteristic related to a number of users in the access queue; a controller, which sets an access criterion based on the determined access queue characteristic; and a detector, located at the access barrier and which determines the variable access parameter of a portable access key when it is brought into the vicinity of the detector. The controller sets the access barrier in its open state if the variable access parameter determined by the detector meets the access criterion.

A method of generating a first oscillator signal having a desired frequency in a first frequency range comprises generating in a voltage controlled oscillator unit a second oscillator signal having a frequency in a second frequency range of at least one octave. The method further comprises selecting said second continuous frequency range to have a lower endpoint in said first frequency range and an upper endpoint above said range; and selectively using the oscillator signal unchanged or dividing it by a division ratio selected from integer powers of the number 2 to obtain said first oscillator signal. By centering the VCO higher than otherwise required and using an additional divider, so that the VCO signal can selectively be used unchanged or divided, a sufficient margin below as well as above the desired range for e.g. drift and tolerances of the VCO is achieved. It also simplifies the VCO design.
