Title: System and device for multiplexing digital sound
Inventor: NAKAMURA SHINICHI
IPC: H04N7/08
Filed: 1993-04-23
Abstract: PURPOSE:To improve the quality of television sound when digital sound is orthogonally multiplexed on a television signal and to powerfully correct an error. CONSTITUTION:A bit stream obtained by compressing a two-channels sound signal in a sound compression device 11 is synchronized with a video field as a bit distribution sequence which is completed by 15 fields by a counter 13 and a control bit generation circuit 15. Then, the signal is accumulated in a memory 19 and an error correction code is added by a device 21 for the respective lines of a memory map. The exclusive OR of a data string after interleaving, which is read out by a read circuit 23, and a PN data string from a PN generator 27 is taken in a circuit 25. It is made random and the spectrum concentration of a multiplex modulation signal is suppressed. An orthogonal multiplex modulator orthogonally multiplexes it on the video signal so as to transmit it. Thus, the perfect periods of the compressed bit stream and the format in a video field unit can be realized, a control code is decoded after the error is corrected and resistance against the error can be improved.

Title: Device for collating finger print
Inventor: ISHIKAWA AKIHIKO
IPC: G06T7/00
Filed: 1989-04-17
Abstract: PURPOSE:To prevent the generation of an illegal input due to a copied finger print by providing the finger print collating device with a finger print input circuit for outputting finger print information to a finger print collating circuit when temperature information is within a previously set reference value. CONSTITUTION:A finger print reader 1 outputs finger print information 101 obtained by reading out the finger print of an operator to be a finger print collating object and a body temperature detector 2 outputs a temperature value 201 obtained by measuring the temperature of the operator's finger read-out by the finger print reader 1. When the temperature value 201 outputted from the detector 2 is within the previously set regulated value, a finger print input circuit 3 sends the finger print information 101 outputted from the reader 1 to a finger print collating circuit 4. The circuit 4 compares/collates the finger print information 501 registered previously and outputted from a finger print storing device 5 with a newly accepted finger print information 301, and at the time of coincidence between both the information, outputs a coincidence signal 401. Consequently, the generation of an illegal input due to a copied finger print can be prevented.

Title: White balance device
Inventor: SHIMADA MASAKI
IPC: H04N9/73
Filed: 1984-05-15
Abstract: PURPOSE:To adjust properly the white balance under iluminating light in flickering by executing the automatic control so as to transmit an appropriate signal to a chrominance signal circuit in accordance with the detected output from a color temperature detection means. CONSTITUTION:A reflected light 1 from a subject is converted into red (R) and blue (B) electrical signals by a red light receiving element 5 and blue light receiving element 6. Then both signals go to R/B signals in a divider 7, which are transmitted to an analog gate 10 and AC amplifier 8. The output of the AC amplifier 8 is compared with a voltage value Vi preset in a comparator 9. When said output exceeds the prescrbed value, the connection of the analog gate 10 is switched. Namely, when there is no flicker, an AC signal will not be detected; therefore the R/B signal added from a terminal 14 is transmitted to a white balance adjustment circuit through an LPF11. On the other hand, if there are flickers, a voltage set in accordance with the color and temperature of the illuminating light in flickering added to a terminal 13 is added to the white balance adjustment circuit.
