Title: Range meter for a camera
Inventor: NAKAJIMA YUJI
IPC: G01S7/4911
Filed: 1990-12-24
Abstract: A range meter for a camera comprises an array of light-projectors IR1-IR5 which project irradiation beams towards subjects SB1, SB2 capable of being photographed and light-receiving moans PT which produces an output signal corresponding to the position or positions thereon at which reflected light is received. Arithmetic means OP calculates the distance to a particular subject, and light-quantity control means EM controls the light-projectors IR1-IR5 so that the quantity of irradiation light produced by an outer light-projecting means of the array is less than that produced by an inner light-projecting means. The light projectors are preferably IR LEDs and the different light quantities may be produced by varying the number or magnitude of pulses fed to each projector. To save time, adjacent projectors may be powered by simultaneous, antiphase pulse trains. The array of light projectors is preferably a row, and the light-receiving means may be a photodiode array. <IMAGE>

Title: Frequency error detecting apparatus
Inventor: KUME ATSUYA
IPC: H04L27/156
Filed: 1991-04-04
Abstract: A frequency error detecting apparatus for an FSK signal communication system in which data symbols are represented by frequencies displaced from a center frequency is adapted to detect a difference between the centre frequency of a received signal and the centre frequency generated by a receiver. The apparatus includes a counter 2 for counting the number of cycles of received signal over a certain time period, and means for correcting the counted number of cycles and producing an error signal. The correction to the counted number may allow for a deviation from the centre frequency of the received signal caused by unequal distribution of data symbols, and the error signal may be produced by comparing 4 the centre frequency represented by the corrected number with the centre frequency of the receiver. In a multivalue FSK system, switch means (81, Fig 8) may switch output between values corresponding to different shift frequencies, the counted number may be multiplied by the outputs of the switch means, and the results accumulated to produce an error signal equal to the difference between the received signal centre frequency and the receiver centre frequency. The error is applied to VCO 7 to correct an internal frequency used for demodulation. The input signal may alternatively be a PSK signal. <IMAGE>

Patent GB-2287162-A (GB)
Title: Transmitting information on a wired-OR bus
Inventor: SARANGDHAR NITIN V
IPC: G06F13/368
Filed: 1995-01-18
Abstract: A data transfer protocol exploits the generally shorter signal settling time occurring following high to low signal voltage transitions than occurs following low to high transitions. Thus the transmission of meaningful information on multiple-driver signal lines is restricted to the assertion of high to low transitions, and the clock period for the bus is based on the voltage settling time resulting from only high to low transitions. Consequently, the transmission of meaningful signals are all within the limits of incident wave switching and a high overall information transmission rate is achieved. For single driver lines, one unit of information per clock cycle is transmitted (302). For multiple driver lines which are correlated with commonly observable events, one unit is transmitted even two clock cycles (306). For multiple driver lines which are not correlated with commonly observable events, one unit per three clock cycles is transmitted (308). Embodiments relate to a multiprocessor computer system having a latched wired-OR bus. <IMAGE>

Title: Activation programming of cellular telephones
Inventor: SHIRAI KAZUHIKO
IPC: H04W8/26
Filed: 1996-05-24
Abstract: A programming code (P-code) module 24 provides parameter information to a Number Assignment Module (NAM) 25 by processing keypad-entered P-codes. The P-code employs variable length coding, using look-up tables, to shorten the number of keypresses necessary to input more frequently used parameter values. To activate the phone, the user provides product and serial number information to a dial-up access centre which then generates a scrambled P-code for entry by the user. The P-code module 24 descrambles, decompresses, and performs an integrity check on the sequence of digits entered by the user. The P-code module 24 simplifies the programming of phones purchased at retail level, enabling the user to perform the programming necessary for activating the phone on a local network. A security arrangement randomly generates two passwords when the phone is activated to prevent unauthorized reprogramming for use on other cellular telephone networks.
