A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide variable controlled dose per pulse to permit scanning a portion of a vehicle at a dose safe for humans and scanning a cargo portion of a vehicle at substantially increased dose per pulse.

Scanning linear accelerator system for producing X-rays of variable controlled dose per pulse

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different dose.

Linear accelerator system for stable pulsing at multiple dose levels

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different doses.

Scanning linear accelerator system for producing X-RAYS of separately controlled energy and dose

Scanning linear accelerator system having stable pulsing at multiple energies and doses

A customer relationship management system wirelessly detects presence and identity of a customer when the customer enters a business establishment. The system captures a visit pattern of the customer based on communication from the wireless device. A relevant marketing message for the customer is determined based on the customer's presence, visit pattern, identity, and location. The marketing message is delivered directly to a wireless device carried to the customer upon a subsequent entry of the customer to the business establishment. Responses of the customer (e.g., purchasing patterns, etc.) are stored for subsequent use in presenting relevant offers.

Reader network system for presence management in a physical retail environment

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of interleaved pulses having different energy levels, for example alternating 4 MeV and 6 MeV pulses or other energies where the difference in levels is at least approximately 1 MeV and less than approximately 5 MeV. The pulse repetition rate can be 100-400 pulses per second or more. In an embodiment, a cool down calculation is combined with automatic frequency control to provide stable energy and dose per pulse even upon restarting of pulsing after an 'off' period of indeterminate duration.

Linear accelerator system with stable interleaved and intermittent pulsing

The circuitry introduced in this invention selectively slows down the functioning of an electronic circuit maintaining a particular state for a prolonged period of time. This circuitry is used not only to achieve the desired effect in maintaining security from electronic thieves trying to circumvent codes but also in other applications such as enabling a circuit to continue to function in the event of a brief loss of power. For example, in an RFID system, if a reader is frequency hopping, a tag loses power for as long as about 400 milliseconds when the reader changes to other frequencies. In a preferred embodiment, the disclosed circuitry is used in conjunction with a destruct sequence.

Integrated circuits with persistent data storage

A tag receives a first code transmitted by an RFID reader. The first code is compared with a second code stored within the tag. If the first code and the second code match, the tag transmits a third code to the RFID reader.

An identification system includes a reader and one or more tags. The reader identifies tags such as radio frequency (RF) tags. The system divides a number space into n bins, wherein each bin is associated with m unique bits of the number space, and the number space contains the identification codes of the tags. A command is issued to test v bits of the number space. A response is received from a tag, wherein the response occurs when a first portion of an identification code of the tag matches the v bits of the number space, a timing of the response corresponds to a particular bin and m unique bits associated with the particular bin correspond to a second portion of the identification code.
