Title: Machine readable use once code
Inventor: ZHITOMIRSKY VICTOR
IPC: G06K19/18
Filed: 2006-02-02
Abstract: A machine readable code is arranged so that in order to successfully read the code, a user must alter the code structure in such a way that it cannot be read again. The code structure may include two superimposed codes, with one of the codes being provided on a removable label (7-3). In this case, the code structure has to be read twice with the user being required to remove the label (7-3) between the first and second readings. The code structures and code readers described can be used in a number of different applications, including a system that allows brand owners to reward consumers for brand loyalty. The codes may be optical, capacitive, magnetic, or printed with ink of differing electromagnetic characteristics. Only one code may be provided, covered with a removable opaque covering, which code must be read before reaction with the atmosphere or light readers the code unreadable after a predetermined time.

Title: Reducing d.c. offset by comparing two variable signals
Inventor: DAWKINS MARK
IPC: H04L25/06
Filed: 2006-03-03
Abstract: First and second variable signals are obtained from downconversion of the same received radio-frequency DAB signal, and may be varied by an amplification means. These variable signals are compared, and a feedback signal is produced in dependence upon the comparison, and fed back to the amplification means. One or both of the variable signals may then be varied in dependence upon the feedback signal so as to reduce any difference between the d.c. level of the first signal and the d.c. level of the second signal. In an embodiment, the feedback signal is increased if the first signal is higher than the second signal by more than a threshold amount, and decreased if the second signal is higher than the first signal by more than a threshold amount.

Title: Ion beam irradiation apparatus
Inventor: NAKAYA MAKOTO
IPC: H01J37/20
Filed: 2006-04-25
Abstract: Three axes that are orthogonal to each other at one point are taken as an X-axis, a Y-axis and a Z-axis. An irradiation angle setting motor (14a) holds a holder (4), and sets an irradiation angle   r  of an ion beam (58) by rotating this holder (4) around a center axis (60) that is parallel to the X-axis. A Y-axis linear motor (20) causes the holder (4) and the irradiation angle setting motor (14a) to ascend and descent in the direction of the Y-axis. A Z-axis linear motor (30) moves the holder (4), the irradiation angle setting motor (14a) and the Y-axis linear motor (20) in the direction of the Z-axis. A control unit (40) operation-controls synchronously the Y-axis linear motor (20) and the Z-axis linear motor (30) so that a substrate holding surface (6) of the holder (4) reciprocates and scans linearly along an S-axis that is parallel to the substrate holding surface (6) and orthogonal to the X-axis. A further embodiment shows the positions of the Y-axis and Z-axis linear motors swapped.

IPC: G06F21/64
Filed: 2007-07-18
Abstract: An authenticated encryption method and apparatus are described in which plaintext data, P, is encrypted, using a secret key, K, to form ciphertext data, C. A message authentication code, MAC, is also formed in dependence on a combination 44 of the ciphertext data, C, and data characteristic of the plaintext data, P', such as a hash 47 of the plaintext data, P. Preferably the combining method is concatenation, however it may also be an exclusive-OR operation. The ciphertext data and the MAC are then output, for example, for storage to a storage medium 46. In a preferred embodiment the data obtained by combining the ciphertext data and the data characteristic of the plaintext is input to a block cipher 45 operating in Galois / Counter Mode (GCM) mode to produce a stored message authentication code dependent on the plaintext data.
