Title: Error-correcting code adapted for memories that store multiple bits per storage cell
Inventor: PATTI ROBERT
IPC: H04L9/00
Filed: 2001-03-13
Granted: 2002-08-21
Abstract: A memory [10] that stores a plurality of data storage words, each data storage word includes a plurality of data storage cells [15] arranged as a plurality of columns of data storage cells [15], at least one of the data storage cells [15] storing data specifying a data value having 3 or more states. The memory [10] includes a plurality of data lines, one such data line [13] corresponding to each column of data storage cells [15]. Each data storage cell [15] sets its state or provides a signal representative of its state via the data line [13] connected to that cell in response to control signals. The memory[10] also includes an error encryption circuit [l 1] for receiving a data word to be stored in the memory [10] and generating therefrom an encrypted data storage word. The encryption circuit [l 1] divides the encrypted data storage word into a plurality of sub-data storage words. The two least significant bits of the sub-data storage words are encrypted via a first error-encryption algorithm and the most significant bits of the sub-data storage words are either not encrypted or encrypted via a second error encryption algorithm, the second error encryption algorithm having a Hamming Distance that is less than the Hamming Distance of the first error-encryption algorithm. An error decrypting circuit [21] generates a corrected data word from the uncorrected sub-data storage words by generating an increment or decrement to be added to an uncorrected sub-data storage word to arrive at a correct sub-data storage word value.

Granted: 2002-04-11
Abstract: A kind of frequency divider circuit for high frequency is disclosed in the present invention, in which a frequency-divided multi-phase signal output that evenly divides a cycle according to the input signal is generated. The invention is composed of an N-series ring-shaped serial amplifier circuit and a bias circuit for modulating current.

Abstract: The invention relates to a method using the digit string grouped by several specified phone numbers sequentially to search specific e-mail address, which sequentially arrange and combine the country code, area code and local phone-no. in phone number as phone number digit string. After sender of e-mail sequentially keys in the country code-area code-local phone no. in the empty column of e-mail software or behind the empty column in the searching dynamic web page installed in specific website, then automatically initiate the search program in the e-mail software or specific website to transmit the sequentially combined phone number digit string to data block in specific website in connection with world wide web or to any data block of web server in connection with Internet for comparison. Thus, the specific e-mail address registered in any of the said data block corresponding to the phone number digit string, after comparison is successful, will automatically transmit two corresponding specific e-mail addresses matching with the phone number digit string to the SMPT mail server pertaining to the sender through Internet. The SMPT mail server automatically forwards the e-mail written by sender to POP mail server of sender through Internet. Sender can then go through Internet to pick up and view the e-mail contents forwarded by the sender from the POP mail server.

Title: Random number generator and method for generating a random number
Inventor: DICHTL MARKUS
IPC: G06F7/58
Filed: 2002-01-24
Granted: 2003-08-21
Abstract: A random number generator includes a noise signal generating device (10) for supplying a noise signal, a sampling device (16) connected between an output of the noise signal generating device and an output of the random number generator and sampling the noise signal in a sampling state and not sampling the noise signal in an idle state. The random number generator further includes a control oscillator (18) for supplying a control alternating signal, the frequency of the control alternating signal of the control oscillator not being rigidly coupled to the frequency of the noise signal. The random number generator further includes an enabling device (20) which puts the sampling device in the sampling state when the noise signal or the signal derived from the noise signal is in a first trigger state, and when, subsequently, the control alternating signal of the control oscillator is in a second trigger state. This is to ensure that the frequency of the output samples of the random number generator depends on the frequency of the noise signal, whereas the phase position is determined by the frequency of the control oscillator. Thus, the frequency of the output samples can be set and adjusted to existing requirements in a simple manner using the frequency setting functionality of the noise signal generating device.

Abstract: The invention is to provide a method of fabricating a rotor including a first rotor lamination and N second rotor laminations, where N is a natural number. Moreover in particular, the rotor is used in a micro-motor. The first rotor lamination and the second rotor laminations all meet a predetermined pattern on which multiple of riveted points are defined. First, the predetermined pattern is stamped on a first metal slice, and then the first metal slice is punched to form multiple of through-holes on the riveted points. Afterward, the predetermined pattern is stamped on a second metal slice, and then the second metal slice is punched to form multiple of protruding points on the riveted points. Next, the predetermined pattern on the first metal slice is aligned with a die meeting the predetermined pattern, and then the first metal slice is punched to form the first rotor lamination into the die. Afterward, the predetermined pattern on the second metal slice is aligned with the die, and then the second metal slice is punched to form the first second rotor lamination into the die such that the first rotor lamination and the first second rotor lamination are riveted together with the through-holes and the protruding points. The last punching step is repeated (N-1) times to form the other second rotor laminations into the die where i is an integer index ranging 1 to (N-1). During the ith repeated punching step, the ith second rotor lamination and the (i+1) second rotor lamination are riveted together with the protruding points thereof. Finally, the rotor laminations, riveted together, are pushed out from the die to obtain the rotor.
