Abstract: An encryption method is taught which chooses certain bytes of data, stored in a particular on-chip memory, as encryption keys. These chosen bytes are used to encrypt themselves, and all of the remaining data in the above mentioned particular memory. The chosen bytes do not have values specifically assigned for encryption, they are merely chosen, according to a rule, from the body of data to be encrypted. When this technique is implemented, each byte of data, stored in the mentioned memory, is combined (for example using an exclusive NOR gate) with one of the designated encryption key bytes prior to disclosure. The user is not required to provide, program, or safeguard a set of key bytes separately. Additionally, no silicon area is wasted in storing such bytes. An intruder would need certain pieces of the original data in order to decipher the results of this encryption technique. Additionally, this technique degrades gracefully. The keys are chosen such that encrypted data does not have a single common dependency. Thus, in the event a single key is discovered, only a very small portion of the encrypted data will be disclosed.

Abstract: A laser (10) provides an output beam to an interferometer (12). A portion of the output beam is directed by a beamsplitter to a receiver (18) as a reference beam while the remaining portion of the output beam passes through the beamsplitter and impinges on a plane mirror reflective surface (14a) mounted upon or integrally formed with or upon a surface of a body of interest, such as rotary actuator or arm (14). The arm has a fixed center of rotation O and rotates through an angular range indicated by theta-max. Phi is the angle of incidence of the laser beam with the arm in its original position when theta equals zero. | OC | and | CD | are distances which locate the intersection point between the arm and the laser beam relative to the center of rotation O when theta equals zero. A corner cube (16) is located at a convergence plane and returns all reflected beams back to the plane mirror and hence to the receiver via the interferometer. The interferometer and receiver operate to provide a determination of the position of the arm relative to a reference position, the determined position being used to cause a servo track or tracks to be written upon a medium at a desired position.

Abstract: A mechanical clutch (52,56) is provided to selectively interconnect a forward (66) or reverse (70) gear member to a transmission shaft (62). The clutch is operated by a servo piston (16) and fork (30) structure. The servo piston is slidably disposed in a housing (12) and urged in the forward select position by a spring (18). The housing and servo piston cooperate to define two fluid chambers (36,42) which are maintained in a separated condition when the forward select position position is established. One chamber (36) is in fluid communication with a fluid system (100,102) that is controlled to provide fluid at two distinct pressure levels, depending upon various vehicle operating parameters. The other chamber (42) is connected with a selectively engageable fluid operated friction clutch (94) which is effective to assist in establishing at least the reverse drive ratio within the transmission. The lowest level of fluid pressure in the one chamber is not sufficient to cause the piston to overcome the spring force and thereby move the clutch to the reverse select position. The second pressure level is, however, sufficient to cause such movement. In the reverse select position, the chambers are fluidly interconnected and the fluid clutch can be engaged by the fluid pressure supplied through the second chamber from the first chamber.

Abstract: Subtractive CDMA demodulation optimally decodes a coded information signal embedded in many other overlapping signals making up a received, composite signal. A radio receiver correlates a unique code corresponding to the desired signal to be decoded with the composite signal. Moreover, after each information signal is successfully decoded, it is recoded and removed from the composite signal. As a result, subsequent correlations are performed with greater accuracy. Subtractive CDMA demodulation is enhanced by decoding the composite signal in the order of strongest to weakest signal strength. Interference caused by the presence of the strongest information signal and the composite signal during the decoding of weaker signals is removed. The individual information signals are assigned a unique block error correction code which is correlated with the composite signal using Fast Walsh transforms. Correlated signals are recoded using inverted Fast Walsh transforms and removed from the composite signal.
